Description

本開示は、冷却装置の運転制御装置に関する。The present disclosure relates to an operation control device for a cooling device.

特許文献１には、外部電源により車載バッテリを充電する場合に、車載バッテリを冷却する冷却装置が開示されている。かかる冷却装置の運転制御装置は、充電地点の位置情報に基づいて充電地点の静寂性要求度を判定する判定部と、空調装置に対し、静寂性要求度が所定値以上の充電地点で充電する場合の空調装置（電動コンプレッサ）の回転数の上限値を、静寂性要求度が所定値未満の充電地点で充電する場合の空調装置（電動コンプレッサ）の回転数の上限値よりも低く設定する制御部と、を備えている。Patent Document 1 discloses a cooling device that cools an on-board battery when the on-board battery is charged by an external power source. The operation control device of the cooling device includes a determination unit that determines the required level of quietness at a charging point based on location information of the charging point, and a control unit that sets an upper limit of the rotation speed of the air conditioner (electric compressor) when charging at a charging point where the required level of quietness is equal to or higher than a predetermined value, lower than an upper limit of the rotation speed of the air conditioner (electric compressor) when charging at a charging point where the required level of quietness is less than the predetermined value.

かかる冷却装置の運転制御装置によれば、静寂性要求度が所定値以上の充電地点で充電する場合の空調装置（電動コンプレッサ）の作動音が、静寂性要求度が所定値未満の充電地点で充電する場合の空調装置（電動コンプレッサ）の作動音よりも小さくなり、周囲の不快感を抑制できる。With this cooling system operation control device, the operating noise of the air conditioner (electric compressor) when charging at a charging point where the quietness requirement level is equal to or higher than a predetermined value is quieter than the operating noise of the air conditioner (electric compressor) when charging at a charging point where the quietness requirement level is less than the predetermined value, thereby reducing discomfort to those around the vehicle.

特許文献１が開示する冷却装置の運転制御装置では、外部充電中に冷却装置の運転を停止できない。The cooling device operation control device disclosed in Patent Document 1 cannot stop the operation of the cooling device during external charging.

上述の事情に鑑みて、本発明の少なくとも一実施形態は、外部充電中に冷却装置の運転を停止できる冷却装置の制御装置を提供することを目的とする。In view of the above circumstances, an object of at least one embodiment of the present invention is to provide a control device for a cooling device that can stop operation of the cooling device during external charging.

（１）本発明の少なくとも一実施形態に係る冷却装置の運転制御装置は、所定電動車両以外の給電設備からの外部充電が可能な前記所定電動車両に搭載され、外部充電中に駆動用バッテリを冷却する冷却装置の運転制御装置であって、ユーザによって操作され、前記外部充電中に前記冷却装置の運転停止を可能にするオン・オフスイッチと、予め定められた条件に基づいて前記冷却装置を運転制御するオート冷却モードの選択を可能にするモード選択スイッチと、を備える。(1) An operation control device for a cooling device in at least one embodiment of the present invention is mounted on a specified electric vehicle capable of external charging from a power supply facility other than the specified electric vehicle, and is an operation control device for a cooling device that cools a drive battery during external charging, and is equipped with an on/off switch that is operated by a user and enables operation of the cooling device to be stopped during the external charging, and a mode selection switch that enables selection of an auto cooling mode that controls operation of the cooling device based on predetermined conditions.

上記（１）の構成によれば、オン・オフスイッチがオフされた場合に、冷却装置の運転が停止される。また、オン・オフスイッチがオンされ、かつ、モード選択スイッチによってオート冷却モードが選択された場合に、予め定めた条件に基づいて冷却装置が運転制御される。これにより、予め定める条件をユーザ又は自動車メーカが適宜設定することにより、ユーザが求める条件で冷却装置を運転制御できる。According to the above configuration (1), when the on/off switch is turned off, the operation of the cooling device is stopped. Also, when the on/off switch is turned on and the auto cooling mode is selected by the mode selection switch, the operation of the cooling device is controlled based on predetermined conditions. This allows the user or the automobile manufacturer to appropriately set the predetermined conditions, thereby allowing the operation of the cooling device to be controlled under conditions desired by the user.

（２）幾つかの実施形態では、上記（１）の構成において、前記外部充電は、家庭用の商用電源から充電される普通充電である。(2) In some embodiments, in the configuration of (1) above, the external charging is normal charging from a household commercial power source.

上記（２）の構成によれば、時間をかけて充電するため、バッテリへの負荷が小さく、冷却装置を停止することができるため、冷却装置による騒音や振動など、車両周辺の環境への影響を抑制することができる。According to the above configuration (2), charging takes place over a long period of time, which reduces the load on the battery and allows the cooling device to be stopped, thereby reducing the impact on the environment around the vehicle, such as noise and vibration caused by the cooling device.

（３）幾つかの実施形態では、上記（１）又は（２）の構成において、前記モード選択スイッチは、前記オン・オフスイッチがオンされた場合に、前記オート冷却モードの選択を可能にする。(3) In some embodiments, in the configuration described above in (1) or (2), the mode selection switch enables selection of the auto cooling mode when the on/off switch is turned on.

上記（３）の構成によれば、オン・オフスイッチがオンされた後に、オート冷却モードの選択が可能になるので、オン・オフスイッチがオフされた状態でオート冷却モードが選択されるのを防止できる。According to the above configuration (3), the auto-cooling mode can be selected after the on/off switch is turned on, so that the auto-cooling mode can be prevented from being selected when the on/off switch is turned off.

（４）幾つかの実施形態では、上記（１）から（３）のいずれか一つの構成において、前記所定電動車両に設けられた騒音検出装置から騒音レベルが入力される騒音レベル入力部と、外部充電時の時刻を管理する充電時刻管理部と、を備え、前記オート冷却モードが選択された場合に、前記騒音レベル入力部から入力された騒音レベル、又は前記充電時刻管理部で管理される前記外部充電時の時刻が含まれる時間帯の少なくとも一方に基づいて、前記冷却装置を運転制御する。(4) In some embodiments, in any one of the configurations (1) to (3) above, a noise level input unit to which a noise level is input from a noise detection device provided in the specified electric vehicle, and a charging time management unit to manage the time of external charging, when the auto cooling mode is selected, operation of the cooling device is controlled based on at least one of the noise level input from the noise level input unit or the time zone including the time of external charging managed by the charging time management unit.

上記（４）の構成によれば、騒音レベル又は時間帯のすくなくとも一方に基づいて冷却装置が運転制御される。例えば、騒音レベルが低い夜間や早朝に冷却装置の運転が停止される。これにより、騒音レベルが低い夜間や早朝において冷却装置の作動音（騒音）を低減できる。According to the above configuration (4), the operation of the cooling device is controlled based on at least one of the noise level and the time period. For example, the operation of the cooling device is stopped at night or early in the morning when the noise level is low. This makes it possible to reduce the operating sound (noise) of the cooling device at night or early in the morning when the noise level is low.

（５）幾つかの実施形態では、上記（１）から（４）のいずれか一つの構成において、前記所定電動車両に設けられたバッテリ制御装置から前記駆動用バッテリの電池温度が入力される電池温度入力部と、車両周りの外気温度が入力される雰囲気温度入力部と、を備え、前記オート冷却モードが選択された場合に、前記電池温度入力部から入力された電池温度、又は、前記雰囲気温度入力部に入力された前記外気温度の少なくとも一方に基づいて、前記冷却装置を運転制御する。(5) In some embodiments, in any one of the configurations (1) to (4) above, a battery temperature input unit to which a battery temperature of the driving battery is input from a battery control device provided in the specified electric vehicle, and an ambient temperature input unit to which an outside air temperature around the vehicle is input, and when the auto cooling mode is selected, operation of the cooling device is controlled based on at least one of the battery temperature input from the battery temperature input unit or the outside air temperature input to the ambient temperature input unit.

上記（５）の構成によれば、駆動用バッテリの電池温度又は車両周りの外気温度の少なくとも一方に基づいて冷却装置が運転制御される。例えば、車両周りの外気温度が高いほど駆動用バッテリの冷却効率が低下するので、車両周りの外気温度が予め定めた温度よりも低い場合に冷却装置の冷却効果が高められる。これにより、駆動用バッテリの冷却効率が高い外気温度で冷却装置の冷却効果が高められ、駆動用バッテリを効率的に冷却できる。According to the above configuration (5), the operation of the cooling device is controlled based on at least one of the battery temperature of the drive battery and the outside air temperature around the vehicle. For example, since the cooling efficiency of the drive battery decreases as the outside air temperature around the vehicle increases, the cooling effect of the cooling device is enhanced when the outside air temperature around the vehicle is lower than a predetermined temperature. As a result, the cooling effect of the cooling device is enhanced at an outside air temperature at which the cooling efficiency of the drive battery is high, and the drive battery can be efficiently cooled.

（６）幾つかの実施形態では、上記（１）から（５）のいずれか一つの構成において、前記所定電動車両に設けられたバッテリ制御装置から前記駆動用バッテリの健全性が入力される健全性入力部を備え、前記オート冷却モードが選択された場合に、前記健全性入力部から入力された前記駆動用バッテリの健全性に基づいて、前記冷却装置を運転制御する。(6) In some embodiments, in any one of the configurations (1) to (5) above, a health input unit is provided to which the health of the drive battery is input from a battery control device provided in the specified electric vehicle, and when the auto cooling mode is selected, the operation of the cooling device is controlled based on the health of the drive battery input from the health input unit.

上記（６）の構成によれば、駆動用バッテリの健全性に基づいて冷却装置が運転制御される。例えば、駆動用バッテリの健全性が高いほど駆動用バッテリが劣化しやすいため、駆動用バッテリの健全性が高いほど目標温度に近づくように冷却装置が運転制御される。これにより、駆動用バッテリの温度が目標温度に近づき、駆動用バッテリの劣化を抑制できる。According to the above configuration (6), the operation of the cooling device is controlled based on the health of the drive battery. For example, the higher the health of the drive battery, the more likely the drive battery is to deteriorate, so the operation of the cooling device is controlled so that the higher the health of the drive battery, the closer the temperature approaches the target temperature. This brings the temperature of the drive battery closer to the target temperature, and deterioration of the drive battery can be suppressed.

（７）幾つかの実施形態では、上記（１）から（６）のいずれか一つの構成において、前記冷却装置は、前記所定電動車両の車両周りの外気を取り込んで前記駆動用バッテリを空冷する冷却ファンを備え、前記オート冷却モードが選択された場合に、車両周りの外気温度が所定温度以上のときは、前記冷却装置の運転を停止し、所定時間経過後、前記車両周りの外気温度が前記所定温度未満となったときに、前記冷却装置の運転を開始する。(7) In some embodiments, in any one of the configurations (1) to (6) above, the cooling device includes a cooling fan that takes in outside air around the specified electric vehicle to cool the drive battery, and when the auto cooling mode is selected, when the outside air temperature around the vehicle is equal to or higher than a predetermined temperature, the operation of the cooling device is stopped, and when the outside air temperature around the vehicle becomes lower than the predetermined temperature after a predetermined time has elapsed, the operation of the cooling device is started.

上記（７）の構成によれば、車両周りの外気温度が所定温度以上のときは、冷却装置の運転が停止される。よって、所定温度を駆動用バッテリの冷却効率が低下する温度とすれば、駆動用バッテリの冷却効率が低下した状態で冷却装置の運転が停止される。一方、冷却装置の運転を停止し、所定時間経過後、車両周りの外気温度が所定温度未満となったときに、冷却装置の運転が開始される。よって、所定温度を駆動用バッテリの冷却効率が低下する温度とすれば、冷却装置の運転を停止し、所定時間経過後、駆動用バッテリの冷却効率が復帰した状態で冷却装置の運転が開始（再開）される。これにより、駆動用バッテリの冷却効率が高い状態で冷却装置が運転され、駆動用バッテリを効率的に冷却できる。According to the configuration of (7) above, when the outside air temperature around the vehicle is equal to or higher than a predetermined temperature, the operation of the cooling device is stopped. Therefore, if the predetermined temperature is set to a temperature at which the cooling efficiency of the driving battery decreases, the operation of the cooling device is stopped in a state where the cooling efficiency of the driving battery decreases. On the other hand, the operation of the cooling device is started when the outside air temperature around the vehicle becomes lower than the predetermined temperature after a predetermined time has elapsed since the operation of the cooling device is stopped. Therefore, if the predetermined temperature is set to a temperature at which the cooling efficiency of the driving battery decreases, the operation of the cooling device is stopped, and after a predetermined time has elapsed, the operation of the cooling device is started (restarted) in a state where the cooling efficiency of the driving battery has returned. As a result, the cooling device is operated in a state where the cooling efficiency of the driving battery is high, and the driving battery can be efficiently cooled.

（８）幾つかの実施形態では、上記（１）から（７）のいずれか一つの構成において、前記冷却装置の運転開始からの時間を管理する冷却運転時間管理部を備え、前記オート冷却モードが選択された場合に、前記冷却運転時間管理部が管理する前記冷却装置の運転開始からの時間に基づいて、前記冷却装置を運転制御する。(8) In some embodiments, in any one of the configurations (1) to (7) above, a cooling operation time management unit is provided that manages the time from the start of operation of the cooling device, and when the auto cooling mode is selected, the operation of the cooling device is controlled based on the time from the start of operation of the cooling device managed by the cooling operation time management unit.

上記（８）の構成によれば、冷却装置の運転開始からの時間に基づいて冷却装置が運転制御される。例えば、冷却装置の運転開始からの時間が夜間になると冷却装置の運転が抑制されるように制御される。これにより、騒音レベルが低い夜間において冷却装置の作動音（騒音）を低減できる。According to the above-mentioned configuration (8), the operation of the cooling device is controlled based on the time from the start of operation of the cooling device. For example, when the time from the start of operation of the cooling device becomes nighttime, the operation of the cooling device is controlled to be suppressed. This makes it possible to reduce the operating sound (noise) of the cooling device during the night when the noise level is low.

（９）幾つかの実施形態では、上記（１）から（８）のいずれか一つの構成において、前記所定電動車両に設けられたバッテリ制御装置から前記駆動用バッテリの充電率が入力される充電率入力部を備え、前記オート冷却モードが選択された場合に、前記充電率入力部に入力される前記駆動用バッテリの充電率に基づいて、前記冷却装置を運転制御する。(9) In some embodiments, in any one of the configurations (1) to (8) above, a charging rate input unit is provided to which a charging rate of the drive battery is input from a battery control device provided in the specified electric vehicle, and when the auto cooling mode is selected, the operation of the cooling device is controlled based on the charging rate of the drive battery input to the charging rate input unit.

上記（９）の構成によれば、駆動用バッテリの充電率に基づいて冷却装置が運転制御される。例えば、駆動用バッテリの充電率が１００％に近づいた状態で冷却装置の運転が継続されると駆動用バッテリが満充電になるまで時間がかかるので、駆動用バッテリの充電率が１００％に近づくと冷却装置の運転が停止される。According to the above configuration (9), the operation of the cooling device is controlled based on the charging rate of the drive battery. For example, if the cooling device continues to operate when the charging rate of the drive battery approaches 100%, it will take a long time for the drive battery to become fully charged, so the operation of the cooling device is stopped when the charging rate of the drive battery approaches 100%.

本発明の少なくとも一実施形態によれば、外部充電中に冷却装置の運転を停止できる。According to at least one embodiment of the present invention, the operation of the cooling device can be stopped during external charging.

以下、添付図面を参照して本発明の幾つかの実施形態について説明する。ただし、実施形態として記載されている又は図面に示されている構成部品の寸法、材質、形状、その相対的配置等は、本発明の範囲をこれに限定する趣旨ではなく、単なる説明例にすぎない。Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of components described as the embodiments or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention.

実施形態にかかる冷却装置１は、外部電源によって駆動用バッテリ１１０を充電できるプラグインハイブリッド自動車（ＰＨＥＶ，ＰＨＶ）や電気自動車（ＥＶ）等の電動車両１００に適用される。外部電源は、例えば、急速充電器、家庭用の商用電源等の給電設備であるが、これらに限られるものではなく、例えば、電源車であってもよい。The cooling device 1 according to the embodiment is applied to an electric vehicle 100 such as a plug-in hybrid vehicle (PHEV, PHV) or an electric vehicle (EV) that can charge a drive battery 110 by an external power source. The external power source is, for example, a power supply facility such as a quick charger or a commercial power source for home use, but is not limited thereto, and may be, for example, a power source vehicle.

図１に示すように、実施形態に係る冷却装置１は、駆動用バッテリ１１０を冷却するための装置であり、例えば、外部電源による充電（以下「外部充電」という）中に駆動用バッテリ１１０を冷却する。実施形態に係る冷却装置１は、例えば、コンプレッサ１１、熱交換器（コンデンサ）１３、エキスパンションバルブ（図示せず）及び熱交換器（エバポレータ）１５によって構成される。これらコンプレッサ１１、熱交換器１３、エキスパンションバルブ及び熱交換器１５は、冷媒が循環する冷凍サイクルを構成する。本実施形態では、コンプレッサ１１は駆動用バッテリ１１０から電気が供給される。また、コンプレッサ１１はエアコン（図示せず）と共用され、エアコン制御装置（エアコンＥＣＵ：Ｅｌｅｃｔｒｏｎｉｃ Ｃｏｎｔｒｏｌ Ｕｎｉｔ）２１によって制御される。また、熱交換器１３にはラジエータファン１７が対向配置され、熱交換器１５には冷却ファン１９が対向配置され、駆動用バッテリ１１０の近傍に設置される。ラジエータファン１７及び冷却ファン１９には補機バッテリ（図示せず）が接続され、補機バッテリからラジエータファン１７及び冷却ファン１９に電気が供給される。As shown in FIG. 1, the cooling device 1 according to the embodiment is a device for cooling a driving battery 110, and cools the driving battery 110 during charging by an external power source (hereinafter referred to as "external charging"). The cooling device 1 according to the embodiment is composed of, for example, a compressor 11, a heat exchanger (condenser) 13, an expansion valve (not shown), and a heat exchanger (evaporator) 15. The compressor 11, the heat exchanger 13, the expansion valve, and the heat exchanger 15 constitute a refrigeration cycle in which a refrigerant circulates. In this embodiment, the compressor 11 is supplied with electricity from the driving battery 110. The compressor 11 is also used in common with an air conditioner (not shown), and is controlled by an air conditioner control device (air conditioner ECU: Electronic Control Unit) 21. A radiator fan 17 is disposed opposite the heat exchanger 13, and a cooling fan 19 is disposed opposite the heat exchanger 15, and the cooling fan 19 is disposed opposite the heat exchanger 15, and is installed near the driving battery 110. An auxiliary battery (not shown) is connected to the radiator fan 17 and the cooling fan 19, and electricity is supplied to the radiator fan 17 and the cooling fan 19 from the auxiliary battery.

そして、コンプレッサ１１で圧縮された冷媒は、高温高圧の冷媒ガスとなって熱交換器１３に送られる。熱交換器１３に送られた冷媒ガスはラジエータファン１７によって冷却（液化）され、高温高圧の液冷媒となってエキスパンションバルブに送られる。エキスパンションバルブに送られた冷媒液は急激に圧力が下がり、低温低圧の冷媒液となって熱交換器１５に送られる。熱交換器１５に送られた冷媒液は、熱交換器１５の周囲から熱を奪い気化する。熱交換器１５の周囲は冷却され、熱交換器１５の近傍に対向配置された駆動用バッテリ１１０も冷却される。The refrigerant compressed by the compressor 11 becomes a high-temperature, high-pressure refrigerant gas and is sent to the heat exchanger 13. The refrigerant gas sent to the heat exchanger 13 is cooled (liquefied) by the radiator fan 17, and becomes a high-temperature, high-pressure liquid refrigerant and is sent to the expansion valve. The pressure of the refrigerant liquid sent to the expansion valve suddenly drops, and it becomes a low-temperature, low-pressure refrigerant liquid and is sent to the heat exchanger 15. The refrigerant liquid sent to the heat exchanger 15 absorbs heat from the surroundings of the heat exchanger 15 and vaporizes. The surroundings of the heat exchanger 15 are cooled, and the driving battery 110 arranged opposite and near the heat exchanger 15 is also cooled.

実施形態に係る冷却装置１は、車両制御装置（ＥＶＥＣＵ）３によって制御される。例えば、冷却装置１が、コンプレッサ１１、熱交換器１３、エキスパンションバルブ（図示せず）及び熱交換器１５で構成される場合に、コンプレッサ１１を制御するエアコン制御装置２１、ラジエータファン１７及び冷却ファン１９が車両制御装置３に接続され、車両制御装置３によって制御される。The cooling device 1 according to the embodiment is controlled by a vehicle control device (EVECU) 3. For example, when the cooling device 1 is composed of a compressor 11, a heat exchanger 13, an expansion valve (not shown), and a heat exchanger 15, an air conditioner control device 21 that controls the compressor 11, a radiator fan 17, and a cooling fan 19 are connected to the vehicle control device 3 and controlled by the vehicle control device 3.

また、車両制御装置３には、駆動用バッテリ制御装置（ＢＭＵ：Ｂａｔｔｅｒｙ Ｍａｎａｇｅｍｅｎｔ Ｕｎｉｔ）２２及びメータ／ナビ２３が接続されている。駆動用バッテリ制御装置２２では、駆動用バッテリ１１０の電池温度、駆動用バッテリ１１０の健全性（ＳＯＨ:Ｓｔａｔｅ Ｏｆ Ｈｅａｌｔｈ）、及び駆動用バッテリ１１０の充電率（
ＳＯＣ：Ｓｔａｔｅ Ｏｆ Ｃｈａｒｇｅ）が管理され、図２に示すように、車両制御装置３には、電池温度入力部３１、健全性入力部３２及び充電率入力部３３が設けられる。 In addition, a drive battery control unit (BMU: Battery Management Unit) 22 and a meter/navigation system 23 are connected to the vehicle control device 3. The drive battery control unit 22 monitors the battery temperature of the drive battery 110, the state of health (SOH) of the drive battery 110, and the charging rate (
As shown in FIG. 2 , the vehicle control device 3 is provided with a battery temperature input unit 31, a battery health input unit 32, and a charging rate input unit 33.

図４および図５に示すように、メータ／ナビ２３には、オン・オフスイッチ４１とモード選択スイッチ４３とが設けられている。オン・オフスイッチ４１は、ユーザによって操作され、外部充電中に冷却装置１の運転停止を可能にするスイッチである。これにより、ユーザによってオン・オフスイッチ４１が操作され、オン・オフスイッチ４１がオフされた場合に、冷却装置１の運転が停止される。4 and 5, the meter/navi 23 is provided with an on/off switch 41 and a mode selection switch 43. The on/off switch 41 is a switch that is operated by a user and enables the operation of the cooling device 1 to be stopped during external charging. Thus, when the on/off switch 41 is operated by the user and turned off, the operation of the cooling device 1 is stopped.

例えば、オン・オフスイッチ４１は、メータ／ナビ２３の画面に表示される操作画像で構成され、デフォルトでオンに設定されており、外部充電中に冷却装置１の運転を可能にする一方、オフを選択することで外部充電中に冷却装置１の運転を停止する。For example, the on/off switch 41 is configured as an operation image displayed on the screen of the meter/navigation 23, and is set to on by default, allowing operation of the cooling device 1 during external charging, while selecting off stops operation of the cooling device 1 during external charging.

モード選択スイッチ４３は、ユーザによって操作され、予め定めた条件に基づいて冷却装置１を運転制御するオート冷却モードの選択を可能にするスイッチである。これにより、ユーザによってモード選択スイッチ４３が操作され、オート冷却モードが選択された場合に、予め定めた条件に基づいて冷却装置１が運転制御される。The mode selection switch 43 is a switch that is operated by a user and enables selection of an auto-cooling mode that controls the operation of the cooling device 1 based on predetermined conditions. Thus, when the user operates the mode selection switch 43 and selects the auto-cooling mode, the operation of the cooling device 1 is controlled based on the predetermined conditions.

例えば、モード選択スイッチ４３は、オン・オフスイッチ４１と同様、メータ／ナビ２３の画面に表示される操作画像で構成され、デフォルトでノーマル（冷却モード）に設定されており、外部充電中に冷却装置１を通常運転する一方、オート冷却モードを選択することで、予め定めた条件に基づいて冷却装置１を運転制御する。For example, the mode selection switch 43, like the on/off switch 41, is configured with an operation image displayed on the screen of the meter/navigation system 23, and is set to normal (cooling mode) by default, so that the cooling device 1 is operated normally during external charging, whereas the auto cooling mode can be selected to control the operation of the cooling device 1 based on predetermined conditions.

例えば、オン・オフスイッチ４１及びオート冷却モードスイッチは、メータ／ナビ２３に設けられたマルチインフォメーションディスプレイスイッチを操作することで表示される「設定モード」画像Ｇ１を選択することにより表示される。例えば、図４に示すように、オン・オフスイッチ４１は、「ＯＦＦ」と「ＯＮ」を示す操作画像Ｇ３３で構成され、モード選択スイッチ４３は、「ＯＮ」を選択した場合に選択可能となる「Ｎｏｒｍａｌ」と「Ａｕｔｏ」を示す操作画像Ｇ３５で構成される。また、例えば、図５に示すように、オン・オフスイッチ４１とオート冷却モードスイッチは、「ＯＦＦ」「ＯＮ」及び「Ａｕｔｏ」を示す操作画像Ｇ５で構成されてもよい。この場合に、「ＯＦＦ」と「ＯＮ」を示す操作画像Ｇ５３がオン・オフスイッチ４１の機能を発揮し、「ＯＮ」と「Ａｕｔｏ」を示す操作画像Ｇ５５がモード選択スイッチ４３の機能を発揮する。For example, the on/off switch 41 and the auto cooling mode switch are displayed by selecting a "setting mode" image G1 displayed by operating a multi-information display switch provided on the meter/navigation system 23. For example, as shown in FIG. 4, the on/off switch 41 is configured with an operation image G33 indicating "OFF" and "ON", and the mode selection switch 43 is configured with an operation image G35 indicating "Normal" and "Auto" which become selectable when "ON" is selected. Also, for example, as shown in FIG. 5, the on/off switch 41 and the auto cooling mode switch may be configured with an operation image G5 indicating "OFF", "ON", and "Auto". In this case, the operation image G53 indicating "OFF" and "ON" performs the function of the on/off switch 41, and the operation image G55 indicating "ON" and "Auto" performs the function of the mode selection switch 43.

また、車両制御装置３には、騒音検出装置２４、ＥＶリモート制御装置２５、車載充電器制御装置２６及びエンジン制御装置２７が接続される。車両制御装置３には、騒音レベル入力部３４、充電時刻管理部３５、及び雰囲気温度入力部３６が設けられている。騒音検出装置２４は、例えば、マイクロフォンを含み、電動車両周辺の騒音レベルを検出する。そして、騒音検出装置２４で検出された騒音レベルは、騒音レベル入力部３４で管理される。ＥＶリモート制御装置２５には、スマートフォン等の携帯端末によって、外部充電開始時間、及び充電開始から冷却装置１の運転開始までの時間が設定される。そして、ＥＶリモート制御装置２５に設定された外部充電開始時間、充電開始から冷却装置１の運転開始までの時間は充電時刻管理部３５で管理される。車載充電器制御装置２６には、普通充電ガン（図示せず）の接続情報が入力される。そして、車載充電器制御装置２６に入力された普通充電ガンの接続情報は充電時刻管理部３５で管理される。エンジン制御装置２７には、吸気温度（車両周りの外気温度）が入力される。そして、エンジン制御装置２７に入力された吸気温度は、車両周りの外気温度として雰囲気温度入力部３６で管理される。Further, the vehicle control device 3 is connected to a noise detection device 24, an EV remote control device 25, an on-board charger control device 26, and an engine control device 27. The vehicle control device 3 is provided with a noise level input unit 34, a charging time management unit 35, and an ambient temperature input unit 36. The noise detection device 24 includes, for example, a microphone, and detects a noise level around the electric vehicle. The noise level detected by the noise detection device 24 is managed by the noise level input unit 34. The external charging start time and the time from the start of charging to the start of operation of the cooling device 1 are set in the EV remote control device 25 by a mobile terminal such as a smartphone. The external charging start time and the time from the start of charging to the start of operation of the cooling device 1 set in the EV remote control device 25 are managed by the charging time management unit 35. The connection information of a normal charging gun (not shown) is input to the on-board charger control device 26. The connection information of the normal charging gun input to the on-board charger control device 26 is managed by the charging time management unit 35. The intake air temperature (outside air temperature around the vehicle) is input to the engine control device 27. The intake air temperature input to the engine control device 27 is managed by an ambient temperature input unit 36 as the outside air temperature around the vehicle.

上述した車両制御装置３は、例えば、演算装置、命令や情報を格納するレジスタ、周辺回路等から構成されるプロセッサ（図示せず）、ＲＯＭ（Ｒｅａｄ Ｏｎｌｙ Ｍｅｍｏｒｙ）やＲＡＭ（Ｒａｎｄｏｍ Ａｃｃｅｓｓ Ｍｅｍｏｒｙ）等のメモリ（図示せず）のほか入出力インターフェース（図示せず）によって構成される。The vehicle control device 3 described above is configured by, for example, a processor (not shown) consisting of an arithmetic unit, a register for storing instructions and information, peripheral circuits, etc., memories (not shown) such as a ROM (Read Only Memory) and a RAM (Random Access Memory), as well as an input/output interface (not shown).

車両制御装置３は、外部充電中に、オン・オフスイッチ４１がオフされた場合に冷却装置１の運転を停止する。冷却装置１の運転が停止される外部充電は、例えば、家庭用の商用電源から充電される普通充電であり、例えば、急速充電器による急速充電の場合には冷却装置１の運転を継続する。尚、普通充電は、家庭用の商用電源から充電されることのほか、電源電流が交流であることや、車載充電器を介して充電されること、急速充電よりも遥かに小さな電圧で充電されること、によって急速充電と区別される。The vehicle control device 3 stops the operation of the cooling device 1 when the on/off switch 41 is turned off during external charging. External charging in which the operation of the cooling device 1 is stopped is, for example, normal charging in which charging is performed from a household commercial power source, and in the case of rapid charging using a rapid charger, for example, the operation of the cooling device 1 is continued. Note that normal charging is distinguished from rapid charging in that, in addition to charging from a household commercial power source, the power source current is AC, charging is performed via an on-board charger, and charging is performed at a much smaller voltage than rapid charging.

車両制御装置３は、オン・オフスイッチ４１がオンされ、かつ、モード選択スイッチ４３によってオート冷却モードが選択された場合に、予め定められた条件に基づいて外部充電中に冷却装置１を運転制御する。これにより、予め定める条件をユーザ又は自動車メーカが適宜設定することにより、ユーザが求める条件で外部充電中に冷却装置１を運転制御できる。The vehicle control device 3 controls the operation of the cooling device 1 during external charging based on predetermined conditions when the on/off switch 41 is turned on and the auto cooling mode is selected by the mode selection switch 43. In this way, the user or the automobile manufacturer can appropriately set the predetermined conditions, thereby enabling the operation of the cooling device 1 during external charging to be controlled under conditions desired by the user.

例えば、図６に示すように、車両制御装置３は、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、騒音レベル入力部３４に入力された騒音レベル、又は充電時刻管理部３５で管理される外部充電時の時刻が含まれる時間帯の少なくとも一方に基づいて外部充電中に冷却装置１を運転制御する。For example, as shown in FIG. 6 , when the on/off switch 41 is turned on and the auto cooling mode is selected, the vehicle control device 3 controls the operation of the cooling device 1 during external charging based on at least one of the noise level input to the noise level input unit 34 or the time period including the time of external charging managed by the charging time management unit 35.

図６に示す例では、騒音レベル入力部３４から入力された騒音レベル及び充電時刻管理部３５で管理される外部充電時の時刻に基づいて制御仕様（電池冷却のレベル）が設定され、当該制御仕様に基づいて冷却装置１が制御される。例えば、騒音レベルと時間帯で区分けされた電池冷却のレベルを実現するように、車両制御装置３は冷却装置１を運転制御する。例えば、騒音レベルが低い夜間や早朝に冷却装置１の運転が停止される。このようにすれば、騒音レベルが低い夜間や早朝において冷却装置１の作動音（騒音）を低減できる。In the example shown in Fig. 6, a control specification (battery cooling level) is set based on the noise level input from the noise level input unit 34 and the time of external charging managed by the charging time management unit 35, and the cooling device 1 is controlled based on the control specification. For example, the vehicle control device 3 controls the operation of the cooling device 1 so as to achieve a battery cooling level classified by noise level and time period. For example, the operation of the cooling device 1 is stopped at night or early in the morning when the noise level is low. In this way, the operating sound (noise) of the cooling device 1 can be reduced at night or early in the morning when the noise level is low.

また、例えば、図７に示すように、車両制御装置３は、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、電池温度入力部３１から入力された電池温度、又は、雰囲気温度入力部３６で管理される車両周りの外気温度の少なくとも一方に基づいて外部充電中に冷却装置１を運転制御する。Also, for example, as shown in FIG. 7 , when the on/off switch 41 is turned on and the auto cooling mode is selected, the vehicle control device 3 controls the operation of the cooling device 1 during external charging based on at least one of the battery temperature input from the battery temperature input unit 31 or the outside air temperature around the vehicle managed by the ambient temperature input unit 36.

図７に示す例では、雰囲気温度入力部３６で管理される車両周りの外気温度に基づいて制御仕様（電池冷却のレベル）が設定され、当該制御仕様に基づいて外部充電中に冷却装置１が運転制御される。例えば、車両周りの外気温度で区分けされた電池冷却のレベルを実現するように、車両制御装置３は冷却装置１を制御する。7, a control specification (battery cooling level) is set based on the outside air temperature around the vehicle managed by the ambient temperature input unit 36, and the operation of the cooling device 1 during external charging is controlled based on the control specification. For example, the vehicle control device 3 controls the cooling device 1 so as to achieve a battery cooling level classified according to the outside air temperature around the vehicle.

例えば、駆動用バッテリ１１０の雰囲気温度が高いほど駆動用バッテリ１１０の冷却効率が低下するので、駆動用バッテリ１１０の雰囲気温度が予め定めた温度よりも高い場合に冷却装置１の運転が停止される。このようにすれば、駆動用バッテリ１１０の冷却効率が高い雰囲気温度で冷却装置１が運転され、駆動用バッテリ１１０を効率的に冷却できる。For example, since the higher the ambient temperature of the driving battery 110, the lower the cooling efficiency of the driving battery 110, the operation of the cooling device 1 is stopped when the ambient temperature of the driving battery 110 is higher than a predetermined temperature. In this way, the cooling device 1 is operated at an ambient temperature at which the cooling efficiency of the driving battery 110 is high, and the driving battery 110 can be cooled efficiently.

また、例えば、図８に示すように、車両制御装置３は、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、健全性入力部３２から入力された駆動用バッテリ１１０の健全性に基づいて外部充電中に冷却装置１を運転制御する。健全性は、ＳＯＨで評価される。尚、ＳＯＨは、初期時（新品時）の満充電容量に対する劣化時（現在）の満充電容量を百分率で表したもので示される。8, when the on/off switch 41 is turned on and the auto cooling mode is selected, the vehicle control device 3 controls the operation of the cooling device 1 during external charging based on the health of the drive battery 110 input from the health input unit 32. The health is evaluated by the SOH, which is expressed as a percentage of the full charge capacity at the time of deterioration (present) relative to the full charge capacity at the initial time (when new).

図８に示す例では、健全性入力部３２から入力されたＳＯＨに基づいて制御仕様が設定され、当該制御仕様に基づいて冷却装置１が制御される。例えば、ＳＯＨで区分けされた電池冷却のレベルを実現するように、車両制御装置３は冷却装置１を制御制御する。例えば、駆動用バッテリ１１０の健全性が高いほど駆動用バッテリ１１０が劣化しやすいため、駆動用バッテリ１１０の健全性が高いほど目標温度に近づくように冷却装置１が運転制御される。このようにすれば、駆動用バッテリ１１０の温度が目標温度に近づき、駆動用バッテリ１１０の劣化を抑制できる。In the example shown in Fig. 8, a control specification is set based on the SOH input from the battery health input unit 32, and the cooling device 1 is controlled based on the control specification. For example, the vehicle control device 3 controls the cooling device 1 so as to achieve a level of battery cooling classified by the SOH. For example, since the higher the health of the driving battery 110, the more likely the driving battery 110 is to deteriorate, the operation of the cooling device 1 is controlled so as to approach the target temperature as the health of the driving battery 110 is higher. In this way, the temperature of the driving battery 110 approaches the target temperature, and deterioration of the driving battery 110 can be suppressed.

また、例えば、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、冷却開始時間入力部（図示せず）から入力された外部充電の開始から冷却装置１の運転開始までの時間に基づいて外部充電中に冷却装置１を運転制御する。Also, for example, when the on/off switch 41 is turned on and the auto cooling mode is selected, the operation of the cooling device 1 is controlled during external charging based on the time from the start of external charging to the start of operation of the cooling device 1, which is input from a cooling start time input unit (not shown).

また、例えば、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、車両周りの外気温度が所定温度以上のときは、外部充電中に冷却装置１の運転を停止する。そして、所定時間経過後、車両周りの外気温度が所定温度未満となったときに、外部充電中に冷却装置１の運転を開始する。車両周りの外気温度が所定温度以上のときは、冷却装置１の運転が停止される。よって、所定温度を駆動用バッテリ１１０の冷却効率が低下する温度とすれば、駆動用バッテリ１１０の冷却効率が低下した状態で冷却装置１の運転が停止される。一方、冷却装置１の運転を停止し、所定時間経過後、車両周りの外気温度が所定温度未満となったときに、冷却装置１の運転が開始される。よって、所定温度を駆動用バッテリ１１０の冷却効率が低下する温度とすれば、冷却装置１の運転を停止し、所定時間経過後、駆動用バッテリ１１０の冷却効率が復帰した状態で冷却装置１の運転が開始（再開）される。これにより、駆動用バッテリ１１０の冷却効率が高い状態で冷却装置１が運転され、駆動用バッテリ１１０を効率的に冷却できる。Also, for example, when the on/off switch 41 is turned on and the auto cooling mode is selected, if the outside air temperature around the vehicle is equal to or higher than a predetermined temperature, the operation of the cooling device 1 is stopped during external charging. Then, after a predetermined time has elapsed, when the outside air temperature around the vehicle becomes lower than the predetermined temperature, the operation of the cooling device 1 is started during external charging. When the outside air temperature around the vehicle is equal to or higher than the predetermined temperature, the operation of the cooling device 1 is stopped. Therefore, if the predetermined temperature is set to a temperature at which the cooling efficiency of the driving battery 110 decreases, the operation of the cooling device 1 is stopped in a state in which the cooling efficiency of the driving battery 110 decreases. On the other hand, when the operation of the cooling device 1 is stopped and the outside air temperature around the vehicle becomes lower than the predetermined temperature after a predetermined time has elapsed, the operation of the cooling device 1 is started. Therefore, if the predetermined temperature is set to a temperature at which the cooling efficiency of the driving battery 110 decreases, the operation of the cooling device 1 is stopped and, after a predetermined time has elapsed, the operation of the cooling device 1 is started (restarted) in a state in which the cooling efficiency of the driving battery 110 is restored. As a result, the cooling device 1 is operated in a state where the cooling efficiency of the driving battery 110 is high, and the driving battery 110 can be cooled efficiently.

また、例えば、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、冷却運転時間管理部が管理する冷却装置１の運転開始からの時間に基づいて、外部充電中に冷却装置１を運転制御する。例えば、冷却装置１の運転開始からの時間が夜間になると冷却装置１の運転が抑制されるように制御される。これにより、騒音レベルが低い夜間において冷却装置１の作動音（騒音）を低減できる。Also, for example, when the on/off switch 41 is turned on and the auto-cooling mode is selected, the operation of the cooling device 1 is controlled during external charging based on the time from the start of operation of the cooling device 1 managed by the cooling operation time management unit. For example, when the time from the start of operation of the cooling device 1 becomes nighttime, the operation of the cooling device 1 is controlled to be suppressed. This makes it possible to reduce the operating sound (noise) of the cooling device 1 during the night when the noise level is low.

また、例えば、オン・オフスイッチ４１がオンされ、かつ、オート冷却モードが選択された場合に、充電率入力部３３に入力される駆動用バッテリ１１０の充電率に基づいて外部充電中に冷却装置１を運転制御する。充電率は、ＳＯＣで評価される。尚、ＳＯＣは、満充電状態を１００％、完全放電状態を０％とする。例えば、駆動用バッテリ１１０の充電率が１００％に近づいた状態で冷却装置１の運転が継続されると駆動用バッテリ１１０が満充電になるまで時間がかかるので、駆動用バッテリ１１０の充電率が１００％に近づくと冷却装置１の運転が停止される。Furthermore, for example, when the on/off switch 41 is turned on and the auto cooling mode is selected, the operation of the cooling device 1 is controlled during external charging based on the charging rate of the driving battery 110 input to the charging rate input unit 33. The charging rate is evaluated by the SOC. The SOC is defined as 100% for a fully charged state and 0% for a fully discharged state. For example, if the operation of the cooling device 1 is continued when the charging rate of the driving battery 110 approaches 100%, it will take time for the driving battery 110 to become fully charged, so the operation of the cooling device 1 is stopped when the charging rate of the driving battery 110 approaches 100%.

図９に示すように、車両制御装置３は、高電圧開始モードにおいて、普通充電開始条件が成立すると普通充電が開始される（ステップＳ１：Ｙｅｓ，ステップＳ２）。普通充電開始条件は、例えば、普通充電口への普通充電コネクタ（普通充電ガン）の接続であり、普通充電口に普通充電コネクタが接続されると、車両制御装置３が、普通充電を開始する。普通充電開始条件が成立しない場合には（ステップＳ１：Ｎｏ）、車両制御装置３は、待機状態となる。9, in the high voltage start mode, the vehicle control device 3 starts normal charging when a normal charging start condition is satisfied (step S1: Yes, step S2). The normal charging start condition is, for example, the connection of a normal charging connector (normal charging gun) to a normal charging port, and when the normal charging connector is connected to the normal charging port, the vehicle control device 3 starts normal charging. If the normal charging start condition is not satisfied (step S1: No), the vehicle control device 3 goes into a standby state.

車両制御装置３は、普通充電を開始すると、オート冷却モードの開始条件が成立しているか否かを判定する（ステップＳ３）。オート冷却モードの開始条件は、例えば、オン・オフスイッチ４１がオフされていないこと、電池温度入力部３１に入力された駆動用バッテリ１１０の電池温度が所定温度（例えば２７°Ｃ）以上であること、及び、普通充電中であること、である。When normal charging is started, the vehicle control device 3 determines whether or not the conditions for starting the auto cooling mode are satisfied (step S3). The conditions for starting the auto cooling mode are, for example, that the on/off switch 41 is not turned off, that the battery temperature of the driving battery 110 inputted to the battery temperature input unit 31 is equal to or higher than a predetermined temperature (e.g., 27° C.), and that normal charging is in progress.

車両制御装置３は、オート冷却モード開始条件が成立すると（ステップＳ３：Ｙｅｓ）、予め定められた条件に基づいて冷却装置１を運転制御する（ステップＳ４）。車両制御装置３は、予め定められた条件に基づいて冷却装置１の運転制御を開始すると、電池冷却の終了条件が成立しているか否かを判定する（ステップＳ５）。電池冷却の終了条件は、例えば、普通充電中でないこと、及び、電池温度入力部３１に入力された駆動用バッテリ１１０の電池温度が所定温度（例えば２２°Ｃ）以下であること、又は、充電率が所定値（例えば９５％）以上であること、である。車両制御装置３は、電池冷却の終了条件が成立すると（ステップＳ５：Ｙｅｓ）、電池冷却を終了する（ステップＳ６）。電池冷却の終了条件が成立しない場合は（ステップＳ５：Ｎｏ）、車両制御装置は冷却装置１の運転制御を継続する。When the auto-cooling mode start condition is satisfied (step S3: Yes), the vehicle control device 3 controls the operation of the cooling device 1 based on a predetermined condition (step S4). When the vehicle control device 3 starts the operation control of the cooling device 1 based on the predetermined condition, it determines whether or not the end condition of the battery cooling is satisfied (step S5). The end condition of the battery cooling is, for example, that the battery is not being charged normally, and that the battery temperature of the driving battery 110 inputted to the battery temperature input unit 31 is equal to or lower than a predetermined temperature (e.g., 22°C), or that the charging rate is equal to or higher than a predetermined value (e.g., 95%). When the end condition of the battery cooling is satisfied (step S5: Yes), the vehicle control device 3 ends the battery cooling (step S6). When the end condition of the battery cooling is not satisfied (step S5: No), the vehicle control device continues the operation control of the cooling device 1.

車両制御装置３は、電池冷却を終了すると、普通充電終了条件が成立しているか否かを判定する（ステップＳ７）。普通充電終了条件は、例えば、普通充電口から普通充電コネクタ（普通充電ガン）の接続解除である。普通充電口から普通充電コネクタが取り外されると（ステップＳ７：ＹＥＳ）、車両制御装置３が、普通充電を終了する（ステップＳ８）。普通充電終了条件が成立しない場合は、（ステップＳ７：Ｎｏ）、車両制御装置３は、ステップＳ３へ戻り、オート冷却モードの開始条件の判定を繰り返す。また、オート冷却モードの開始条件が成立しない場合は（ステップＳ３：Ｎｏ）、車両制御装置３は、ステップＳ７へ進み、普通充電終了条件の判定を行う。When the battery cooling is ended, the vehicle control device 3 determines whether or not the normal charging end condition is satisfied (step S7). The normal charging end condition is, for example, disconnection of the normal charging connector (normal charging gun) from the normal charging port. When the normal charging connector is removed from the normal charging port (step S7: YES), the vehicle control device 3 ends normal charging (step S8). If the normal charging end condition is not satisfied (step S7: No), the vehicle control device 3 returns to step S3 and repeats the determination of the start condition of the auto cooling mode. Also, if the start condition of the auto cooling mode is not satisfied (step S3: No), the vehicle control device 3 proceeds to step S7 and determines whether or not the normal charging end condition is satisfied.

実施形態に係る冷却装置１の制御装置（車両制御装置３）によれば、オン・オフスイッチ４１がオンされ、かつ、モード選択スイッチ４３によってオート冷却モードが選択された場合に、予め定められた条件に基づいて外部充電中に冷却装置１を運転制御する。これにより、予め定める条件をユーザ又は自動車メーカが適宜設定することにより、ユーザが求める条件で冷却装置１を運転制御できる。According to the control device (vehicle control device 3) of the cooling device 1 according to the embodiment, the operation of the cooling device 1 is controlled during external charging based on predetermined conditions when the on/off switch 41 is turned on and the auto cooling mode is selected by the mode selection switch 43. This allows the user or the automobile manufacturer to appropriately set the predetermined conditions, thereby enabling the operation of the cooling device 1 to be controlled under conditions desired by the user.
