  Incidentally, there are cases where an electronic device such as an ECU that controls the power storage device or an ECU that controls the temperature control device is mounted around the power storage device. In this case, if the temperature of the heat medium is changed when adjusting the temperature of the power storage device, heat exchange may occur between the electronic device and the heat medium, and the temperature of the electronic device may change excessively. However, if the temperature change range of the heat medium is reduced, the temperature of the power storage device cannot be sufficiently adjusted.

Note that the above situation is not limited to the ECU, and is common to electronic devices arranged around the power storage device.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a power storage system capable of suppressing an excessive temperature change of an electronic device while adjusting the temperature of the power storage device.

  In order to achieve the above object, the invention according to claim 1 is an electronic device, a chargeable / dischargeable power storage device, a temperature control device that adjusts the temperature of the power storage device using a heat medium, and the power storage device. And a case for housing the electronic device, wherein the case includes a temperature-controlled space in which the power storage device is housed and temperature is adjusted by the heat medium, and the electronic device A partition section is provided for partitioning the storage space in which the storage space is stored.

  According to this invention, the internal space of the case is partitioned into the temperature-controlled space and the accommodating space. Then, the temperature of the power storage device accommodated in the temperature controlled space is adjusted by adjusting the temperature using the heat medium in the temperature controlled space. On the other hand, since the electronic device is housed in a housing space that is different from the temperature-controlled space, it is possible to avoid the influence of the heat medium directly on the electronic device. Thereby, the excessive temperature change of an electronic device can be suppressed. Therefore, it is possible to achieve both the temperature adjustment of the power storage device and the suppression of an excessive temperature change of the electronic device.

  The invention according to claim 2 is characterized in that the partition portion regulates inflow of the heat medium from the temperature-controlled space into the housing space. According to this invention, the direct inflow of the heat medium from the temperature-controlled space to the housing space is regulated by the partition portion. Thereby, it is possible to avoid the temperature of the housing space being directly adjusted by the heat medium. Therefore, the excessive temperature change of the accommodation space resulting from a heat medium can be suppressed, and the excessive temperature change of an electronic device can be suppressed.

  According to a third aspect of the present invention, the electronic device includes at least one of a power storage control unit that controls the power storage device and a temperature adjustment control unit that controls the temperature control device. According to this invention, for example, by storing the power storage control means in the storage space, the power storage device and the power storage control means can be arranged close to each other while suppressing the direct influence of the heat medium on the power storage control means. . Thus, the influence of noise and the like can be suppressed, so that malfunction of the power storage device can be suppressed.

Even in the configuration in which the temperature adjustment control means is accommodated in the accommodation space, the above-described effects can be obtained due to the relationship between the temperature adjustment device and the temperature adjustment control means.
According to a fourth aspect of the present invention, the partition portion thermally connects the first storage portion that forms the temperature-controlled space and the second storage portion that forms the storage space. Features. According to this invention, each accommodating part is thermally connected. Thereby, heat exchange occurs between the first housing part and the second housing part. Therefore, the heat of the heat medium is transmitted to the housing space via the first housing portion and the second housing portion, and the temperature of the electronic device is adjusted. In this case, an excessive temperature change in the storage space can be suppressed even when the temperature of the heat medium changes greatly by passing through each storage portion having a heat capacity. That is, in the accommodation space, it is possible to perform indirect temperature adjustment through each accommodation portion, not direct temperature adjustment due to the flow of the heat medium. Therefore, in a configuration in which the electronic device and the power storage device are housed in separate spaces, appropriate heat can be transmitted to the electronic device, and the electronic device can be brought to an appropriate temperature.

  According to this invention, an excessive temperature change of the electronic device can be suppressed while adjusting the temperature of the power storage device.

  Hereinafter, an embodiment of a power storage system according to the present invention will be described with reference to FIGS. 1 and 2. This power storage system is mounted on a vehicle (passenger car, industrial vehicle, etc.) and used to drive a travel motor. In FIG. 1, for convenience of drawing, a part of the case is shown in a cutaway manner, and a part of the configuration (wiring, part of a connector, etc.) is omitted.

  As shown in FIG. 1, the power storage system 10 includes various devices such as a battery module 11 that charges and discharges, a temperature adjustment device 12 that adjusts the temperature of the battery module 11, and the like, and a case 13 that houses these devices. ing.

  The case 13 includes a plurality of cases that divide the internal space into a plurality of spaces. Specifically, the case 13 houses a module case 21 (first housing portion) that houses the battery module 11 and the temperature control device 12. And a temperature control case 22. The module case 21 and the temperature control case 22 each have a rectangular parallelepiped shape, and the length dimension in the long side direction of both is set to be the same. The module case 21 and the temperature control case 22 are fixed (integrated) in a state where the side walls on the long side are in contact with each other.

  As shown in FIG. 2, the battery module 11 includes a plurality of secondary batteries 11a and a battery case 11b that accommodates each of the secondary batteries 11a. Each secondary battery 11a is connected in series with each other, and is connected to external terminals 11c and 11d provided on the battery case 11b.

  Incidentally, as shown in FIG. 2, each of the external terminals 11 c and 11 d is connected to a load (such as a travel motor) via a system main relay 31 provided in the module case 21 and a connector 32 provided in the module case 21. (Not shown). When the system main relay 31 is turned on / off, the power supply to the load is turned on / off.

  The module case 21 is provided with a service plug 33. The service plug 33 relays the electrical connection between the external terminal 11c and the system main relay 31, and cuts off the electrical connection when the module case 21 is opened.

  As shown in FIGS. 1 and 2, the temperature control device 12 takes in air as a heat medium from the outside of the case 13, and heats or cools the air to form a compartment in the module case 21, specifically, the module case 21. Is supplied to the temperature-controlled space 21a, and the air in the temperature-controlled space 21a is discharged out of the case 13. Specifically, the temperature control device 12 includes an intake pipe 41 and an exhaust pipe 42 that connect the outside air and the temperature-controlled space 21a. One end of each of the pipes 41 and 42 passes through the contact portion between the module case 21 and the temperature control case 22 and is connected to the temperature control space 21a, and the other end passes through the temperature control case 22 and connects to the outside air. Has been. Further, the temperature control device 12 includes an intake fan 43 provided in the middle of the intake pipe 41 and an exhaust fan 44 provided in the middle of the exhaust pipe 42. Thus, outside air flows into the temperature controlled space 21a via the intake pipe 41 and circulates in the temperature controlled space 21a. Then, the air in the temperature-controlled space 21 a is discharged out of the case 13 through the exhaust pipe 42.

  As shown in FIG. 2, the temperature adjustment device 12 includes a temperature adjustment unit 45 that adjusts the temperature of the heat medium. The temperature adjustment unit 45 is provided so as to straddle the intake pipe 41 and the exhaust pipe 42. The temperature adjustment unit 45 is configured to heat or cool the air passing through the intake pipe 41, and specifically includes a Peltier element and an application circuit that applies a voltage to the Peltier element. The air passing through the intake pipe 41 is heated or cooled by the temperature adjustment unit 45 and flows into the temperature-controlled space 21a. Specifically, the temperature adjustment unit 45 periodically varies the temperature of the air flowing into the temperature-controlled space 21a so that the temperature of the battery module 11 having a relatively large heat capacity is constant. Thereby, the battery module 11 is adjusted to an appropriate temperature. In the following description, the air heated or cooled by the temperature adjustment unit 45 is also referred to as temperature adjustment air.

  As shown in FIG. 1, a plurality of through holes 11e are formed in the battery case 11b, and ventilation is performed between the air in the battery case 11b and the air in the temperature-controlled space 21a. ing.

  As shown in FIG. 2, the power storage system 10 includes a battery ECU 51 that controls the battery module 11 as an electronic device, and a temperature adjustment ECU 52 (temperature adjustment control means) that controls the temperature adjustment device 12. The battery ECU 51 is configured to receive detection results of various sensors provided in the battery case 11b, specifically, a temperature detection sensor and a power storage detection sensor (not shown). Based on the detection result, each secondary battery 11a of the battery module 11 is controlled. The temperature control ECU 52 is configured to be able to receive information related to the temperature of the battery module 11 from the battery ECU 51, and controls the temperature control unit 45 based on the information, and flows into the temperature-controlled space 21a (temperature-controlled air). ) Periodically change the temperature.

  Here, each said ECU51, 52 is arrange | positioned in the space different from the to-be-temperature-controlled space 21a through which temperature-controlled air circulates. Specifically, the case 13 includes a first housing case 61 (second housing portion) that defines a first housing space 61a in which the battery ECU 51 is housed, and a second housing space 62a in which the temperature control ECU 52 is housed. And a second housing case 62 for partitioning.

  The first housing case 61 has a rectangular parallelepiped shape, and the length dimension in the longitudinal direction of the first housing case 61 and the length dimension in the short direction of the module case 21 are the same. Then, the side wall 21b on the short side of the module case 21 and the side wall 61b on the long side of the first housing case 61 are integrated with each other. In this case, assuming that the first housing case 61 and the module case 21 are one case, each of the side walls 21b and 61b, which are contact points, is divided into two cases (the module case 21 and the first housing case). 61). In the following description, the side walls 21b and 61b are collectively referred to as a first partition wall 71.

  The second housing case 62 has a rectangular parallelepiped shape. The second storage case 62 has a length in the longitudinal direction that is the same as the length in the short direction of the first storage case 61, and the length in the short direction is the width of the temperature control case 22. It is formed to be the same as the length dimension. The second storage case 62 has a short side wall 62 b in contact with the short side wall 22 a of the temperature control case 22 and a long side wall 62 c on the short side of the first storage case 61. It is fixed in contact with the side wall 61c. In the following description, the contact point between the temperature control case 22 and the second storage case 62 is referred to as a second partition wall 72, and the contact point between the first storage case 61 and the second storage case 62 is referred to as a third partition wall 73. say.

  As described above, the cases 21, 22, 61, 62 are integrated in a state where the adjacent ones are in contact with each other. That is, it can be said that the case 13 is composed of the respective cases 21, 22, 61, 62 that divide one space into four.

  As shown in FIG. 2, the battery ECU 51 and the battery module 11 are electrically connected via a connector 81 formed on the first partition wall 71. Further, the temperature control ECU 52 and the temperature control unit 45 are electrically connected via a connector 82 formed on the second partition wall 72. The battery ECU 51 and the temperature control ECU 52 are electrically connected via a connector 83 formed on the third partition wall 73. Thereby, in the structure where the space of the case 13 is divided into a plurality of spaces, the electrical connection of each device is ensured.

  Here, each case 21, 22, 61, 62 is formed of a heat transfer material having a predetermined heat capacity, and is formed of, for example, iron, aluminum, resin, or the like. In this embodiment, in each case 21, 22, 61, 62, heat can be transferred through the contact location. For example, since the module case 21 and the first housing case 61 are in contact with each other at the first partition wall 71, part of the heat applied to the module case 21 is transmitted to the first housing case 61. Yes. That is, it can be said that the first partition wall 71 thermally connects the module case 21 and the first housing case 61.

Next, the effect | action of the electrical storage system 10 of this embodiment is demonstrated below.
The battery ECU 51 is housed in the first housing space 61a, which is a space different from the temperature-controlled space 21a into which the temperature-controlled air flows while the battery module 11 is housed. Specifically, the temperature of the temperature-controlled air is restricted from flowing into the first storage space 61a by the first partition wall 71 that partitions the temperature-controlled space 21a and the first storage space 61a. It is a space where the flow of temperature-controlled air is blocked. Thus, the battery ECU 51 is not directly affected by the temperature-controlled air.

  Since the module case 21 and the first housing case 61 are thermally connected via the first partition wall 71, heat exchange is performed between the first housing case 61 and the module case 21. For this reason, the heat of temperature control air is transmitted to the 1st accommodation space 61a via module case 21 and the 1st accommodation case 61 (the 1st partition 71).

  Here, since the module case 21 and the first housing case 61 have a predetermined heat capacity, the temperature change of the module case 21 and the first housing case 61 changes when the temperature of the temperature-controlled air periodically varies. Smaller than temperature change of temperature-controlled air. Therefore, the temperature of the first accommodation space 61a to which the heat of the first accommodation case 61 is transmitted does not change excessively.

According to the embodiment described in detail above, the following excellent effects are obtained.
(1) The temperature-controlled space 21a into which the battery module 11 is housed and the air (temperature-controlled air) heated or cooled by the temperature control unit 45 flows, and the temperature-controlled space 21a is a first space that is separate from the temperature-controlled space 21a. A first partition wall 71 that partitions the housing space 61a was formed. And battery ECU51 was accommodated in the 1st accommodation space 61a. Thereby, it can suppress that the influence of temperature control air reaches the 1st accommodation space 61a directly, adjusting the temperature of the battery module 11 by temperature control air. Therefore, even in a situation where the temperature change of the temperature-controlled air is large, the temperature of the battery ECU 51 can be within an appropriate range.

  In particular, in general, the heat capacity of the battery module 11 is larger than the heat capacity of the battery ECU 51. For this reason, in order to adjust the temperature of the battery module 11, a large amount of heat is required. Therefore, the temperature change of the temperature-controlled air tends to be large in order to ensure a large amount of heat. When the battery ECU 51 having a relatively small heat capacity is exposed to temperature-controlled air having a large temperature change, the temperature change of the battery ECU 51 becomes large. However, disposing the battery module 11 and the battery ECU 51 apart from each other so as not to be affected by the temperature-controlled air is not preferable from the viewpoint of space. Further, from the viewpoint of suppressing the occurrence of malfunction due to noise, it is desirable that the battery ECU 51 that is the control subject and the battery module 11 that is the control object are arranged close to each other.

  On the other hand, according to the present embodiment, one space includes a temperature-controlled space 21a into which the battery module 11 is stored and temperature-controlled air flows, and a first storage space 61a in which the battery ECU 51 is stored. By forming the first partition wall 71 that is divided into two, the above-mentioned disadvantages can be avoided.

  (2) The 1st partition 71 was comprised so that inflow of the temperature control air from the to-be-controlled space 21a to the 1st accommodating space 61a might be controlled. Thereby, the situation where the temperature of the 1st accommodation space 61a is directly adjusted by temperature control air is avoided. Therefore, an excessive temperature change in the first accommodation space 61a can be suppressed.

  (3) The module case 21 and the first housing case 61 are thermally connected via the first partition wall 71. As a result, the heat of the temperature-controlled air is transmitted into the first accommodation space 61 a via the module case 21 and the first accommodation case 61. In this case, since the module case 21 and the first housing case 61 have a predetermined heat capacity, the temperature change of the module case 21 and the first housing case 61 is smaller than the temperature change of the temperature-controlled air. Therefore, the temperature change in the first accommodation space 61a is smaller than the temperature change of the temperature-controlled air. That is, in the first housing space 61a, indirect temperature regulation through the module case 21 and the first housing case 61 is performed, not direct temperature regulation using temperature-controlled air. Therefore, the battery ECU 51 can be maintained at a temperature within an appropriate range by suppressing an excessive temperature change of the battery ECU 51.

  In particular, the side wall 21b on the short side of the module case 21 and the side wall 61b on the long side of the first housing case 61 are in contact with each other. Thereby, the case 13 is compact as a whole without forming unevenness. Moreover, since the contact area is small compared to the configuration in which the first housing case 61 is in contact with the entire side wall on the long side of the module case 21, heat is hardly transmitted.

  (4) Similar to the battery ECU 51, the temperature adjustment ECU 52 is accommodated in the second accommodation space 62a, which is a separate space from the temperature controlled space 21a. Specifically, a second accommodation case 62 that accommodates the temperature adjustment ECU 52 and is in contact with the first accommodation case 61 and the temperature adjustment case 22 is separately provided. Thereby, also about temperature control ECU52, there can exist the effect of (1)-(3) mentioned above.

  In particular, by forming the first accommodation space 61a in which the battery ECU 51 is accommodated and the second accommodation space 62a in which the temperature control ECU 52 is accommodated, the effect of temperature change in one accommodation space is caused in the other accommodation space. It becomes difficult. Thereby, even if it is a case where temperature of one accommodation space changes excessively by some abnormality, it can suppress that the influence reaching the other accommodation space.

In addition, you may change the said embodiment as follows.
In the embodiment, the module case 21 and the first housing case 61 are thermally connected, but the present invention is not limited to this. For example, as shown in FIG. 3, the first heat insulating material 101 may be provided in the first housing case 61 so as to be in contact with the side wall 61 b constituting the first partition wall 71. Thereby, the heat from the module case 21 can be shut off. Similarly, the second heat insulating material 102 may be provided in the second housing case 62 so as to be in contact with the side wall 62 b constituting the second partition wall 72. However, if attention is paid to the fact that the temperature of the battery ECU 51 can be indirectly adjusted, it is preferable to thermally connect the module case 21 and the first housing case 61.

  In addition, about each heat insulating material 101,102, it is not restricted to the structure provided only in the location adjacent to a contact part, It is good also as a structure provided in the whole internal peripheral surface. Further, the configuration is not limited to the configuration provided in the first storage case 61 or the second storage case 62, and may be configured in the module case 21, for example.

Moreover, it is good also as a structure which replaces with the structure which provides each heat insulating material 101,102, and forms the site | part which comprises the 1st partition 71 (and site | part which comprises the 2nd partition 72) with a heat insulating material.
In addition, in the first housing case 61, a heat insulating material may be provided so as to be in contact with a wall portion other than the side wall 61b constituting the first partition wall 71. In this case, the heat transfer of the module case 21 can be allowed while blocking the heat transfer of the outside air. Thereby, in the battery ECU 51, indirect temperature control by the temperature control device 12 can be performed while suppressing the influence of outside air.

  In the embodiment, the module case 21 and the first housing case 61 are integrated in a state where the side wall 21b of the module case 21 and the side wall 61b of the first housing case 61 are in contact with each other. Although it was set as the structure which forms the temperature-controlled space 21a and the 1st accommodating space 61a which were made, it is not restricted to this. For example, as shown in FIG. 4, a power storage side case 111 that houses the battery module 11 and the battery ECU 51 is provided, and the internal space of the power storage side case 111 is partitioned into a temperature-controlled space 21a and a first storage space 61a. The first partition 112 may be formed.

  Similarly, a temperature adjustment side case 113 for accommodating the temperature adjustment device 12 and the temperature adjustment ECU 52 is provided, and the internal space of the temperature adjustment side case 113 is divided into a space for accommodating the temperature adjustment device 12 and a second accommodation space 62a. It is good also as a structure which forms the 2nd partition 114 divided into. In this case, each of the partition walls 112 and 114 may be formed of a heat transfer material or a heat insulating material.

  In embodiment, although battery ECU51 and temperature control ECU52 were employ | adopted as an electronic device, it is not restricted to this, Other electronic devices may be sufficient. However, from the viewpoint of placing the control subject and the control target close to each other in order to reduce noise, a configuration in which at least one of the ECUs 51 and 52 is housed as an electronic device is preferable.

  In the embodiment, the battery ECU 51 and the temperature control ECU 52 are housed in separate spaces. However, the present invention is not limited to this, and both may be housed in the same space. In this case, since it is not necessary to provide the connector 83 for connecting both, the configuration can be simplified and downsized.

  In the embodiment, the configuration related to the exhaust (the exhaust pipe 42 and the exhaust fan 44) is disposed on the side relatively close to the first partition wall 71, and the configuration related to the intake (the intake pipe 41 and the intake fan 43) is the first. Although it arrange | positioned in the side far from 1 partition 71, it is not restricted to this, You may arrange | position these conversely. In this case, the first partition wall 71 is easily exposed to the temperature-controlled air before circulating through the temperature-controlled space 21a. Thereby, the heat by temperature control air can be suitably transmitted to the 1st partition 71.

  However, if the configuration related to the exhaust is disposed on the side relatively closer to the first partition 71 and the configuration related to the intake is disposed on the side relatively far from the first partition 71, the temperature-controlled air and Air conditioned by heat exchange between the air in the temperature-controlled space 21a is supplied to the first partition 71, and an excessive temperature change in the first accommodation space 61a can be suppressed.

  In the embodiment, the temperature control case 22 and the second storage case 62 are provided on the sides of the module case 21 and the first storage case 61, respectively. However, the configuration is not limited to this and is stacked in the vertical direction. It is good. In this case, the intake pipe 41 and the exhaust pipe 42 are vertically penetrated.

  In addition, the first housing case 61 may be disposed so as to contact the upper and lower surfaces of the module case 21. In short, the specific arrangement of the module case 21 and the first housing case 61 is arbitrary as long as the module case 21 and the first housing case 61 are fixed in a state where they are in contact with each other.

  A connecting member that connects the cases 21 and 61 may be provided between the side wall 21 b on the short side of the module case 21 and the side wall 61 b on the long side of the first housing case 61. In this case, both can be thermally connected by forming a connection member with a heat-transfer material. That is, the mode of thermally connecting the cases 21 and 61 includes not only a mode in which both cases are in direct contact but also a mode through a connecting member.

  In embodiment, although the battery case 11b and the 1st partition 71 are not in direct contact, it is not restricted to this, It is good also as a structure which contacts both. Moreover, it is good also as a structure which forms one part or all part of the side wall 21b by the side of the short side of the module case 21 with the battery case 11b. In this case, since the temperature change of the battery case 11b is smaller than the temperature change of the temperature-controlled air due to the heat capacity of the battery case 11b, an excessive temperature change of the first accommodation space 61a can be suppressed.

In addition, the battery case 11b may be omitted if attention is focused on the temperature adjustment of the secondary battery 11a.
○ The arrangement mode of the battery ECU 51 in the first housing case 61 is arbitrary. For example, when attention is focused on reducing the influence of temperature change of the temperature-controlled air, the battery ECU 51 is connected to the side wall that forms the first partition wall 71. It is preferable to arrange it near the side wall opposite to 61b. On the other hand, from the viewpoint of reducing the influence of outside air, it is preferable to arrange the battery ECU 51 closer to the side wall 61b. The same applies to the temperature control ECU 52.

O It is good also as a structure which provides separately the temperature control part (for example, fan) which adjusts the temperature of the 1st accommodating space 61a. However, from the viewpoint of simplification of the configuration, the above embodiment is preferable.
In the embodiment, the first partition wall 71 completely blocks the flow of temperature-controlled air from the temperature-controlled space 21a to the first accommodating space 61a. However, the present invention is not limited to this. By forming, it is good also as a structure which accept | permits inflow of a part of temperature control air within the range in which the excessive temperature change of battery ECU51 does not generate | occur | produce.

  In the embodiment, air is used as a heat medium for temperature adjustment. However, the present invention is not limited to this. For example, a liquid such as water may be used. In this case, a pump is provided in place of each of the fans 43 and 44. The temperature adjustment ECU 52 may be configured to adjust the liquid temperature based on the temperature in the temperature-controlled space 21a.

In embodiment, although the electrical storage system 10 was mounted in the vehicle, it is not restricted to this, It is good also as a structure mounted in the other apparatus.
In embodiment, although the secondary battery 11a was employ | adopted as an electrical storage apparatus, it is not restricted to this, Other electrical storage apparatuses, such as an electric double layer capacitor, may be sufficient.
