<< First Embodiment >>

  FIG. 1 is a schematic diagram of a charging system including a charging device according to an embodiment of the present invention. FIG. 2 is a block diagram of the charging apparatus of this example. The charging system of this example is provided in a parking lot of a shopping mall, a parking lot of a facility that provides a car sharing service for electric vehicles, a parking lot of a company that uses an electric vehicle as a company car, etc. It is done.

  As shown in FIG. 1, the charging system in this example charges a traveling battery (not shown) of the vehicle 300 and includes a charging device 100. The vehicle 300 in the present embodiment is a vehicle having a motor generator as a power source and a battery such as a running battery that charges and discharges the motor generator, for example, an electric vehicle or a plug-in type hybrid car. Etc. can be illustrated.

  An operation panel 2 that is a touch panel is provided on the surface of the charging device 100. For example, a charging operator (for example, a driver or the like) who performs a charging operation touches a button on the operation panel 2 according to the guidance displayed on the operation panel 2 when charging the battery of the vehicle 300 to start charging. And operation for charge control, such as completion | finish of charge, can be performed. In addition, while the vehicle 300 is being charged, a guidance screen for receiving a charge reservation from another vehicle is displayed on the operation panel 2, and a person who wants to make a charge reservation touches a button displayed on the operation panel to charge the vehicle. Reservations can be made.

  The charging device 100 is a charging stand that charges the traveling battery of the vehicle 300 by supplying electric power to the vehicle 300. The charging device 100 includes a charger 1 including a power converter that converts AC power of the commercial AC power source 200 into DC power and boosts the DC power to a predetermined voltage. The charger 1 converts the AC power. The supplied direct current is supplied to the battery of the vehicle 300 via the charging cable 101.

  As shown in FIG. 1, a charging connector 102 is attached to the tip of the charging cable 101, and the charging operator attaches the charging connector 102 to a power supply inlet 301 of the vehicle 300 so that the charging cable 101 is attached. Via, the charging device 100 and the battery of the vehicle 300 are electrically connected.

  As shown in FIG. 2, the charging device 100 includes a charger 1, an operation panel 2, a temperature sensor 3, and a control unit 10. The charging device 100 is connected to an AC power source 200. A charging connector 102 is connected to the power output side of the charging apparatus 100 via a charging cable 101.

  The charger 1 has an inverter and the like, and is a charging circuit for charging the battery of the vehicle 300. Charger 1 is controlled based on a control signal from control unit 10, converts AC power supplied from AC power supply 200 into power suitable for charging a battery for traveling, and converts the power into vehicle 300. The battery is charged by supplying the battery. The operation panel 2 is a touch panel provided on the surface of the charging device 100, and displays a button for starting charging, a button for ending charging, a guidance screen, and the like. When the charging operator touches the button, the operation panel 2 transmits a signal corresponding to the button, for example, an operation signal for starting charging or an operation signal for ending charging to the control unit 10. .

  The temperature sensor 3 is a sensor for detecting the environmental temperature (ambient temperature) of the environment where the charging apparatus 100 is set.

  The control unit 10 includes a charging reservation receiving unit 11 and a charging time setting unit 12. The control unit 10 is a controller for controlling the charger 1, the operation panel 2, and the temperature sensor 3, and controls the entire charging device 100. The charging reservation accepting unit 11 accepts a charging reservation for charging using the same charger 1 from the vehicle other than the vehicle 300 being charged using the charger 1 after charging of the vehicle being charged is completed. The charging time setting unit 12 sets the charging time of the battery of the vehicle 300, in other words, the time during which power is supplied from the charger 1 to the battery. As will be described later, the charging time setting unit 12 sets the charging time according to the state of accepting the charge reservation by the charge reservation accepting unit 11.

  Next, control of the charging device 100 of this example will be described with reference to FIGS. 1 and 2. First, the charging control of the charger 1 will be described.

The charging device 100 of this embodiment are determined maximum time charging time (T _max) in advance, as a rule, once the power supply time per charge does not exceed the maximum charging time (T _max) . Then, as will be described later, the charging device 100 charges the battery with the charging time set by the charging time setting unit 12, and when the charging time is reached from the time when the charging of the battery is started, or the charging capacity of the battery When the battery reaches full charge, the charging is terminated.

  When vehicle 300 is connected to charging connector 102 and the charging operator presses a charging start button displayed on operation panel 2, control unit 10 controls charger 1 and is set by charging time setting unit 12. Charging starts at the specified charging time. The controller 10 monitors the capacity of the battery while the battery is being charged. And the control part 10 complete | finishes charge, when the capacity | capacitance of a battery reaches full charge before reaching the set charge time. Further, even when the capacity of the battery has not reached full charge, the control unit 10 also terminates charging when, for example, an operation for forcibly terminating charging is performed by a charging operator.

On the other hand, when the elapsed time from the charging start time reaches the charging time before the battery capacity reaches full charging, the control unit 10 ends the charging. When the charging is terminated, the control unit 10 displays that the charging is terminated on the display of the charging device 100.

  Next, charging reservation control by the charging reservation receiving unit 11 will be described. In this example, in order to determine whether there is a vehicle waiting to be charged by the charging device 100, a system that accepts a reservation is installed.

  The charging reservation receiving unit 11 controls the operation panel 2 to display a display screen for receiving a charging reservation from the user. For example, when the vehicle 300 is being charged by the charging device 100, the charging reservation receiving unit 11 displays a button for receiving a charging reservation on the operation panel 2. Then, when the user touches the button, a signal indicating that a charge reservation has been made is transmitted from the operation panel 2 to the charge reservation accepting unit 11, and the charge reservation accepting unit 11 accepts the reservation based on the signal, and the charge reservation It will be in a state that has been.

  In this example, the number of vehicles that can accept a charge reservation is limited, for example, one. Therefore, when a charge reservation is made, the charge reservation acceptance unit 11 displays on the operation panel 2 that the reservation is filled, and does not display a button for accepting the charge reservation. In addition, when charging is not performed by the charging apparatus 100 and it is not necessary to accept a charge reservation, the charge reservation accepting unit 11 does not display a button for accepting a charge reservation.

  That is, for example, when the three vehicles are charged in order by the charging device 100, the charging operator of the second vehicle touches a button indicating that the charging reservation is accepted during charging of the first vehicle. Then, the charging reservation receiving unit 12 accepts the charging reservation from the second vehicle, and the charging reservation of the second vehicle is confirmed. During the charging of the first vehicle, the charging reservation receiving unit 11 does not accept charging reservations from vehicles other than the second vehicle, so the third vehicle is charged until the charging of the first vehicle is completed. Can not do. When the first charging is completed, a frame for accepting a charging reservation is vacant, and the third vehicle can make a charging reservation.

  The control unit 10 determines that there is a vehicle waiting for charging when the charging reservation is received by the charging reservation accepting unit 11. If the charging reservation is not reserved by the charging reservation receiving unit 11, the control unit 10 performs charging. Judge that there is no vehicle waiting. And the control part 10 sets the flag for showing the state of a charge vehicle, and the state of the presence or absence of a charge reservation.

  First, in a state where the charging device 100 is not used and there is no charging vehicle or charging reservation vehicle, in other words, in the initial state of the charging control of this example, the control unit 10 sets the flag to “0”. When the vehicle 300 is being charged by the charger 1 and no charging reservation is made by the charging reservation receiving unit 11, the control unit 10 sets the flag to “1”. When the vehicle 300 is being charged by the charger 1 and a charging reservation is made by the charging reservation receiving unit 11, the control unit 10 sets the flag to “2”.

  After the charging reservation is made by the charging reservation receiving unit 11, if the vehicle that has made the charging reservation is being charged, the control unit 10 sets the flag to “3”. When the vehicle that has made a charge reservation is being charged and the charge reservation accepting unit 11 has not made a charge reservation, the control unit 10 sets the flag to “4”. When the vehicle that has made a charge reservation is being charged and the charge reservation accepting unit 11 makes a charge reservation, the control unit 10 sets the flag to “5”.

Next, control of the charging time setting unit 12 will be described. The charging time setting unit 12 is set with a coefficient (ratio) (R ₁ ) for adjusting the charging time according to the charge reservation acceptance state. The coefficient (R ₁ ) is a value smaller than 1. Charging time setting unit 12 to set the charging time to a time shorter than the maximum charging time _{(T max)} is multiplied by the coefficient to the maximum charging time _{(T max) (R 1)} . On the other hand, when the charging time is not set to be shorter than the maximum charging time (T _max ), the charging time setting unit 12 sets the maximum charging time (T _max ) as the charging time without using the coefficient (R ₁ ). To do.

  A specific example in which the charging time setting unit 12 sets the charging time short will be described. If a charging reservation is received from another vehicle during charging of a vehicle that has not been charged, the charging time setting unit 12 sets a shorter time than the remaining charging time immediately before the charging reservation is entered. Thereby, this example can advance the charge start time of the vehicle that has made a charge reservation by advancing the charge end time of the vehicle that has been previously charged, and shorten the waiting time for charging the vehicle. Can do.

When charging a vehicle that has been charged, the charging time setting unit 12 sets the charging time to a time shorter than the maximum charging time (T _max ). When a charge reservation is made, there is a possibility that a vehicle traffic jam for using the charging apparatus 100 has occurred, and there is a possibility that vehicles other than the vehicle that made the charge reservation are waiting for charging. Therefore, in this example, when charging a vehicle that has been charged, the charging waiting time is shortened by shortening the charging time.

In the charging time setting unit 12, a minimum charging time ( _Tmin ) of the charger 1 is set as a lower limit value of the charging time. As described above, if a charge reservation is made during charging of the vehicle, the remaining charging time may be shortened. However, for example, when a charge reservation is made just before the end time of the set charging time, the remaining charging time is multiplied by the coefficient (R ₁ ), even though the remaining charging time is short, and the remaining charging time is further shortened. Even so, the charging end time cannot be advanced sufficiently.

Therefore, the charging time setting unit 12 compares the calculated time calculated by multiplying the remaining charging time by the coefficient (R ₁ ) and the minimum charging time (T _min ), and calculates the calculated time to the minimum charging time (T _min ), the charging time is not shortened. On the other hand, when the calculation time is longer than the minimum charging time (T _min ), the charging time setting unit 12 multiplies the remaining charging time by a coefficient (R ₁ ) to shorten the remaining charging time. As a result, when the remaining charge time is short and the charge end time cannot be shortened even if the charge time is shortened, the charge time setting unit 12 shortens the charge time from the minimum charge time (T _min ). Prohibit that.

In addition, when a charging reservation is made from another vehicle while charging the vehicle that has been reserved for charging, the charging time setting unit 12 prohibits shortening the charging time of the vehicle that has reserved the charging. For example, in the case where three vehicles are charged in order by the charging device 100, and when charging reservations are made in order, when charging of the second vehicle is completed after charging of the first vehicle, The charging time setting unit 12 sets the charging time of the second vehicle as the time obtained by multiplying the maximum charging time (T _max ) by the coefficient (R ₁ ). If a charge reservation is made from the third vehicle during charging of the second vehicle, if the charge time of the second vehicle is further shortened, the charge time of the second vehicle can be sufficiently secured. There is a possibility that the battery of the second vehicle cannot be fully charged. For this reason, the charging time setting unit 12 prohibits shortening the charging time of the vehicle that has made a charge reservation when a charge reservation is made from another vehicle while the vehicle that has made a charge reservation is being charged.

In the following, the contents of control in the control unit 10 will be described after dividing the charge reservation acceptance state of the vehicle 300 into cases. First, a description will be given of charging control for a vehicle that has not been reserved for charging, where there is no charging reservation from another vehicle during charging (normal charging control). The control unit 10 sets the flag to “0” in the initial state, and sets the flag to “1” when receiving a signal to start charging from the operation panel 2. The charging time setting unit 12 sets the maximum charging time (T _max ) as the charging time. The control unit 10 starts charging at the set maximum charging time (T _max ) while managing the state of charge (SOC) of the battery. Then, the control unit 10 ends the charging when the elapsed time from the charging start time reaches the maximum charging time (T _max ) or when the battery reaches full charge.

Next, a description will be given of charging control for the first vehicle that has not been reserved for charging, in which there is a charging reservation from a second vehicle that is another vehicle during charging. From the start of charging until the reservation for charging is made, the control unit 10 sets the flag to “1”, and the charging time setting unit 12 charges the maximum charging time (T _max ). Charging control is performed by setting the time. In the middle of charging, when the control unit 10 receives a signal for reserving charging from the operation panel 2, the charging reservation receiving unit 11 receives the charging reservation based on the signal, and the charging reservation is completed. .

Since the vehicle that is being charged is a vehicle that has not been reserved for charging, the charging time is shortened according to the length of the remaining charging time. When the charge reservation accepting unit 11 detects that the charge reservation has been made, the control unit 10 causes the charge time setting unit 12 to calculate the remaining charge time by a coefficient (R ₁ ) and a minimum charge time ( T _min ). When the calculation time is longer than the minimum charging time (T _min ), the charging time setting unit 12 sets the calculation time to the remaining charging time, and the control unit 10 performs charging control. On the other hand, when the calculation time is equal to or shorter than the minimum charging time (T _min ), the charging time setting unit 12 does not change the charging time, and the control unit 10 performs charging control.

When the charge reservation accepting unit 11 accepts the charge reservation, the charge reservation accepting state changes, so the control unit 10 changes the flag from “1” to “2”. And the vehicle which reserved the charge is charged in time shorter than the maximum charge time ( _Tmax ) at the time of charge. For this reason, the control unit 10 changes the flag from “2” to “3” so as to identify the state of the charge reservation at the time of charge control of the second vehicle.

Next, a case will be described in which the charging control is performed for a vehicle that has made a charge reservation, and there is no charge reservation from another vehicle during charging. When charging the vehicle for which charging has been reserved, the control unit 10 changes the flag from “3” to the flag “4”, and the charging time setting unit 12 determines the maximum charging time (T _max) based on the state of the flag. ) Is multiplied by a coefficient (R ₁ ) to shorten the charging time. Then, the control unit 10 ends the charging when the elapsed time from the charging start time reaches the set charging time or when the battery reaches full charge.

Next, a case where there is a charge reservation from the second vehicle, which is another vehicle during charging, in the charge control of the first vehicle that has made a charge reservation will be described. From the start of charging until the charging reservation from the second vehicle is entered, the control is the same as the charging control of the vehicle that has made the above-mentioned charging reservation, so the control unit 10 changes the flag from “3” to flag “4”. The battery is charged with the time obtained by multiplying the maximum charging time (T _max ) by the coefficient (R ₁ ) as the charging time. In the middle of charging, when the control unit 10 receives a signal to reserve charging from the operation panel 2, the charging time of the first vehicle has already been shortened, so the charging time setting unit 12 is shorter than the charging time. do not do.

When the charge reservation accepting unit 11 accepts the charge reservation, the accepting state of the charge reservation changes, and therefore the control unit 10 changes the flag from “4” to the flag “5”. The second vehicle that has made a reservation for charging is charged in a time shorter than the maximum charging time (T _max ) during charging. For this reason, the control unit 10 changes the flag from “5” to “3” so as to identify the state of the charge reservation at the time of charge control of the second vehicle.

  As described above, the control unit 10 controls the charger 1 by setting the charging time according to the charge reservation reception state of the charge reservation reception unit 11. In addition, as described below, the charging time setting unit 12 sets the charging time according to the temperature detected by the temperature sensor 3, and the control unit 10 controls the charger 1 based on the charging time.

For example, when the temperature of the environment in which the charging apparatus 100 is set is low, such as in a midnight time zone in a cold region, the charging efficiency of the battery may be lower than in the daytime. And since the temperature sensor 3 has detected the external temperature of the charging device 100, the charging time setting part 12 sets the temperature coefficient ((alpha)) for adjusting charging time according to the detected temperature of the temperature sensor 3. The charging time is set by multiplying the maximum charging time (T _max ) by the temperature coefficient (α). The temperature coefficient (α) is a value greater than 1.

The controller 10 is preset with a threshold temperature for determining whether or not to change the charging time. The threshold temperature is a threshold set in advance based on the environment in which the charging apparatus 100 is set, the charging efficiency with respect to the environmental temperature, and the like. Then, the control unit 10 compares the detected temperature of the temperature sensor 3 with the threshold temperature. When the detected temperature is higher than the threshold temperature, the control unit 10 determines that the environmental temperature of the charging device 100 is high and it is not necessary to lengthen the charging time, and the charging time setting unit 12 sets the temperature coefficient (α). Control is performed so as not to multiply the maximum charging time (T _max ). On the other hand, when the detected temperature is lower than the threshold temperature, the control unit 10 determines that the environmental temperature of the charging device 100 is low and the charging time needs to be increased, and the charging time setting unit 12 determines the temperature coefficient (α ) _Is multiplied by the maximum charging time (T _max ) to control to increase the charging time.

Thereby, when the temperature detected by the temperature sensor becomes lower than the threshold temperature in a midnight time zone in a cold region, the charging time setting unit 12 performs charging longer than the maximum charging time (T _max ) based on the temperature coefficient (α). You can set the time. As a result, this example can provide a charging system that is more convenient for the user.

  A control procedure of the charging apparatus 100 of this example will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing the control procedure of the charging apparatus of this example. FIG. 4 is a flowchart showing charging time setting control based on the temperature detected by the temperature sensor 3 in the control process shown in FIG.

  When the main switch of the charging apparatus 100 of this example is turned on, in step S1, the control unit 10 sets a flag to “0” as an initial state. In step S <b> 2, based on the operation signal from operation panel 2, control unit 10 detects whether or not a charging start instruction has been issued by the charging operator. If an operation signal indicating a charge start command is detected, the process returns to step S3. If an operation signal indicating a charge start command is not detected, the process returns to step S2.

In step S3, the control unit 10 checks the state of the flag. When the flag state is “0”, the charging control is performed for the vehicle that has not made a reservation for charging. In step S4, the charging time setting unit 12 sets the maximum charging time (T _max ) to the charging time (T _m). ), The controller 10 sets the flag to “1” in step S5, and proceeds to step S8.

On the other hand, if the flag status is "3" is carried out charging control of the vehicle in which the charging reservation, charge time setting unit in step S6 12 is the maximum charging time (T _max) the coefficients (R ₁₎ Is set to the charging time (T _m ), the control unit 10 sets the flag to “1” in step S7, and the process proceeds to step S8.

In step S _< b _> 8, the charging time setting unit 12 sets the charging time (T _n ) by correcting the charging time (T _m ) according to the temperature detected by the temperature sensor 3. The calculation control of the charging time (T _n ) will be described later.

In step S9, the remaining charging time (T _r ) is measured by counting down from the charging time (T _n ) while starting charging the battery with the charging time (T _n ) set in step S8. Start. In step S <b> 10, control unit 10 detects whether there is a charge reservation from another vehicle during charging of the battery based on the operation signal of operation panel 2. If the charge reservation is not detected, the process proceeds to step S17 and the battery is continuously charged.

On the other hand, if a charge reservation is detected, in step S11, the control unit 10 checks the state of the flag in order to determine whether the vehicle being charged is a vehicle that has made a charge reservation. To do. When the flag is in a state of "1", at step S12, the charging time calculation unit 12 and the remaining charging time _{(T r)} to the coefficient _{(R 1)} a calculation time obtained by multiplying _{(T r} × _R 1) And the minimum charging time (T _min ). If the calculated time (T _r × R ₁ ) is longer than the minimum charging time (T _min ), in step S13, the charging time setting unit 12 sets the calculated time (T _r × R ₁ ) as the remaining charging time. Then, the control unit 10 changes the calculation time (T _r × R ₁ ) to the remaining charge time and continues charging the battery. In step S14, the control unit 10 sets the flag from “1” to “2”, and proceeds to step S17.

On the other hand, returning to step S12, if the calculated time (T _r × R ₁ ) is equal to or shorter than the minimum charge time (T _min ), the current remaining charge time cannot be shortened. Without changing, in step S15, the control unit 10 sets the flag from “1” to “2”, and proceeds to step S17.

  Returning to step S11, if the flag state is not “1”, that is, if the flag state is “4”, the currently charged vehicle is a vehicle that has been reserved for charging and has already been charged. Since the time has become shorter, the control unit 10 sets the flag from “4” to “5” in step S16 without changing the remaining charging time of the vehicle, and proceeds to step S17.

In step S <b> 17, control unit 10 determines whether the end of charging or the end of charging due to the battery reaching full charge is detected based on the operation signal of operation panel 2. If the end of charging has not been detected, the control unit 10 determines whether or not the current remaining charging time (T _r ) has become zero in step S18. If the remaining charging time (T _r ) is not zero, the process returns to step S10 to continue charging.

On the other hand, when the remaining charging time (T _r ) is zero, the control unit 10 stops the output of power from the charger 1, ends the charging of the battery, and proceeds to step S19. Moreover, returning to step S17, when the end of charging is detected, the control unit 10 stops the output of power from the charger 1, ends the charging of the battery, and proceeds to step S19.

  In step S19, the control unit 10 checks the state of the flag. If the flag is “1”, the next vehicle to be charged is a vehicle that has not been reserved for charging, so the control unit 10 sets the flag to “0” and returns to step S2. When the flag is “2”, since the next vehicle to be charged is a vehicle that has been charged, the control unit 10 sets the flag to “3” and returns to step S2. When the flag is “4”, since the next vehicle to be charged is a vehicle that has not been reserved for charging, the control unit 10 sets the flag to “0” and returns to step S2. If the flag is in the state of “5”, the next vehicle to be charged is the vehicle that has made a charge reservation, so the control unit 10 sets the flag to “3” and returns to step S2.

  In the control shown in FIG. 3, when the main switch is turned off, the control unit 10 ends the control process of this example, deviating from the control flow of FIG. 3.

  Next, the control procedure of the charging time setting control in step S8 of FIG. 3 will be described with reference to FIG.

In step S <b> 81, control unit 10 controls temperature sensor 3 to detect the environmental temperature of charging device 100. In step S82, the control unit 10 compares the detected temperature with the threshold temperature. When the detected temperature is higher than the threshold temperature, the charging time setting unit 12 sets the charging time (T _m ) calculated in steps S4 and S6 as the charging time (T _n ), and proceeds to step S6 in FIG. On the other hand, when the detected temperature is equal to or lower than the threshold temperature, in step S58, the charging time setting unit 12 multiplies the charging time ( _Tm ) calculated in steps S4 and S6 by the temperature coefficient (α), The charging time (T _n ) is calculated, and the process proceeds to step S9 in FIG.

  As described above, according to the present invention, the charging reservation receiving unit 11 that receives a charging reservation for charging using the charger 1 from a vehicle other than the vehicle that is being charged, and the charging reservation receiving state of the charging reservation receiving unit 11 And a charging time setting unit 12 that sets the charging time of the vehicle being charged and the charging time of the vehicle that has reserved the charging. Thus, in this example, it is possible to reduce the charging waiting time because the charging time is adjusted after determining whether there is a vehicle waiting for charging depending on whether there is a charging reservation.

Further, in this example, when the charging reservation is not made, the charging time of the vehicle 300 to be charged is set to the maximum charging time (T _max ), and when the charging reservation is made, the charging time of the vehicle 300 to be charged is set. _Is set to a time shorter than the maximum charging time (T _max ). As a result, if there is a vehicle waiting to be charged later, the charging time of the vehicle that has been charged earlier can be shortened, and the charging end time can be shortened. Can be shortened.

Further, in this example, the charging time of the vehicle that has made a charge reservation is set to a time shorter than the maximum charging time (T _max ). As a result, in this example, not only the charging time of the vehicle that has been charged first, but also the charging time of the subsequent vehicle that has reserved the charge is shortened, so that the fairness when the charging system is convenient can be maintained. .

  Further, in this example, three vehicles charge in order and make a charge reservation in order, and the charge reservation acceptance unit 11 accepts the third charge reservation during the second charge. When the charging reservation is made from the second vehicle, the charging time setting unit 12 prohibits shortening the charging time of the second vehicle. Thereby, this example can prevent further shortening the charging time of the second vehicle, which has already been shortened, and can secure the charging time for charging the battery.

In this example, the charging time setting unit 12 prohibits the remaining charging time of the vehicle being charged from being shorter than the minimum charging time (T _min ). As a result, if the remaining charging time is already short, and the charging end time cannot be sufficiently advanced even if it is shorter, the control process for shortening the charging time can be omitted, and is included in the control unit 10. Can reduce the burden on the CPU.

  Moreover, in this example, when the charge reservation reception part 11 receives the charge reservation from the 2nd vehicle during charge of the 1st vehicle, until the charge of the 1st vehicle is finished, the 1st vehicle and Charge reservations from vehicles other than the second vehicle are not accepted. Thereby, the number of vehicles which accept a charge reservation can be limited, and it can prevent that a control flow becomes complicated.

  In this example, the charging time is set according to the temperature detected by the temperature sensor 3. Thereby, it is possible to control the charging time in accordance with the external temperature of the charging apparatus 100, and it is possible to provide a charging apparatus that is highly convenient for the user.

In this example, the temperature coefficient (α) is set to a value larger than 1, but the temperature coefficient (α) may be set to a value smaller than 1. Thereby, when the environmental temperature of the charging device 100 is low, the rotation rate of the charging control can be increased. Further, in this example, when a charge reservation is made and the temperature detected by the temperature sensor 3 is equal to or lower than the threshold temperature, the maximum charging time (T _max ) is multiplied by a temperature coefficient (α) greater than 1. Thus, the charging time may be set. As a result, when the environmental temperature of the charging device 100 is low and there is a vehicle waiting for charging, the charging time can be shortened, so that the charge control rotation rate can be increased while shortening the charging waiting time. .

  The charging time setting unit 12 corresponds to a “charging time setting unit” according to the present invention, and the charging reservation receiving unit 11 corresponds to a “charging reservation receiving unit”.
