Abstract: An electric vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit includes a compressor, an outdoor heat exchanger, a first indoor heat exchanger, a first expansion valve, a second expansion valve, and a second indoor heat exchanger. The control device repeats an operation of performing the other of a first operation and a second operation after performing one thereof when a remaining capacity of a power storage device is equal to or larger than a predetermined value. In the first operation, the first expansion valve is not decompressed and the second expansion valve is decompressed. In the second operation, the first expansion valve is decompressed and the second expansion valve is not decompressed.

Abstract: A motor-driven vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit has a compressor, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. The indoor heat exchanger exchanges heat with the refrigerant compressed by the compressor. The refrigerant which passes through the indoor heat exchanger is decompressed by the expansion valve, and the outdoor heat exchanger exchanges heat with the decompressed refrigerant and allows the refrigerant to return to the compressor. When the remaining capacity of the power storage device is equal to or more than a predetermined value, the control device operates the compressor and decreases a passing-through air volume of a first air guide device that controls a passing-through air volume of the outdoor heat exchanger.

Abstract: An electric vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit includes a compressor, an outdoor heat exchanger, an expansion valve, a first indoor heat exchanger, and a heating decompression valve. The heating decompression valve changes a passage resistance between the compressor and the outdoor heat exchanger. The control device increases the passage resistance by the heating decompression valve when the remaining capacity of the power storage device is equal to or larger than a predetermined value.

Abstract: An electric vehicle includes an electric motor, an electrical storage device, an air-conditioning apparatus and a controller. A coolant circuit of the air-conditioning apparatus has a compressor, an outdoor heat exchanger, an expansion valve for cooling, and an evaporator. The evaporator has a heat storage member. In a case in which regenerative braking by the electric motor is performed when the state of charge of the electrical storage device is the predetermined value or more, the controller controls the air-conditioning apparatus such that a temperature of the evaporator is decreased so as to be lower than a temperature of the evaporator when a state of charge of the electrical storage device is less than a predetermined value.
