Abstract

A vehicle includes a vehicle interior, a first temperature adjustment circuit, a battery, a second temperature adjustment circuit a heat exchange part, and a control device. During charging of the battery by the external power supply, the control device is configured to cool the battery by controlling the second temperature adjustment circuit. During charging of the battery by the external power supply, the control device is configured to cool the vehicle interior by controlling the first temperature adjustment circuit when a state of charge of the battery is equal to or greater than a predetermined value and a vehicle interior temperature-related value related to a temperature of the vehicle interior is equal to or greater than a threshold.

First claim

What is claimed is:

1 . A vehicle comprising:
a vehicle interior; a first temperature adjustment circuit including a compressor, a condenser, an expansion valve, and an evaporator, the first temperature adjustment circuit being configured to cool the vehicle interior; a battery configured to be charged by receiving electric power from an external power supply; a second temperature adjustment circuit configured to cool the battery; a heat exchange part configured to perform heat exchange between a first medium flowing through the first temperature adjustment circuit and a second medium flowing through the second temperature adjustment circuit; and a control device configured to control the first temperature adjustment circuit and the second temperature adjustment circuit, wherein during charging of the battery by the external power supply, the control device is configured to:
cool the battery by controlling the second temperature adjustment circuit; and
when a state of charge of the battery is equal to or greater than a predetermined value and a vehicle interior temperature-related value related to a temperature of the vehicle interior is equal to or greater than a threshold, cool the vehicle interior by controlling the first temperature adjustment circuit.

2 . The vehicle according to claim 1 ,
wherein when cooling the vehicle interior during charging of the battery, the control device assigns cooling capacity of the first temperature adjustment circuit to cooling of the battery in preference to cooling of the vehicle interior.

3 . The vehicle according to claim 2 ,
wherein the cooling capacity of the first temperature adjustment circuit assigned to cooling of the battery is determined based on a threshold temperature at which output of the battery is limited and based on a temperature of the battery during charging.

4 . The vehicle according to claim 3 ,
wherein when the vehicle travels after charging of the battery, the control device assigns the cooling capacity of the first temperature adjustment circuit to cooling of the battery in preference to cooling of the vehicle interior so that the temperature of the battery does not exceed the threshold temperature.

5 . The vehicle according to claim 1 ,
wherein the control device ends cooling of the vehicle interior when charging of the battery ends.

6 . The vehicle according to claim 1 ,
wherein the control device cools the vehicle interior during charging of the battery only when permission is given by a user.

7 . The vehicle according to claim 1 ,
wherein the control device cools the vehicle interior during charging of the battery when an interval between a scheduled end time of charging of the battery and a traveling start time is equal to or less than a predetermined time based on a charging schedule and a traveling schedule.

8 . The vehicle according to claim 1 ,
wherein the battery is charged by constant current control until the state of charge of the battery reaches the predetermined value, and is charged by constant voltage control when the state of charge of the battery is equal to or greater than the predetermined value.

9 . A vehicle comprising:
a vehicle interior; a first temperature adjustment circuit including a compressor, a condenser, an expansion valve, and an evaporator and the first temperature adjustment circuit being configured to cool the vehicle interior; a battery configured to be charged by receiving electric power from an external power supply; a second temperature adjustment circuit configured to cool the battery; a heat exchange part configured to perform heat exchange between a first medium flowing through the first temperature adjustment circuit and a second medium flowing through the second temperature adjustment circuit; and a control device configured to control the first temperature adjustment circuit and the second temperature adjustment circuit, wherein during charging of the battery by the external power supply, the control device is configured to:
prohibit cooling of the vehicle interior by controlling the first temperature adjustment circuit while charging of the battery is under constant current control; and
permit cooling of the vehicle interior by controlling the first temperature adjustment circuit after charging of the battery is shifted from the constant current control to constant voltage control.

10 . The vehicle according to claim 9 ,
wherein the vehicle interior is cooled by using electric power from the external power supply.
