Abstract: A thermal management system for a vehicle includes a high-temperature side pump that draws and discharges a heat medium, a compressor that draws and discharges a refrigerant in a refrigeration cycle, a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the high-temperature side pump, a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the high-temperature side pump and outside air, and a pump control unit that controls an operation of the high-temperature side pump such that the operation of the high-temperature side pump is continued even after the compressor is stopped. Thus, the cycle efficiency exhibited when restarting the compressor can be improved.

Abstract: A heat medium discharge side of a first pump and a heat medium discharge side of a second pump are connected to a first switching valve in parallel with each other. Respective heat medium inlet sides of a plurality of temperature adjustment devices are connected to the first switching valve in parallel with each other. Respective heat medium outlet sides of the temperature adjustment devices are connected to a second switching valve in parallel with each other. A heat medium suction side of the first pump and a heat medium suction side of the second pump are connected to the second switching valve in parallel with each other. Each of the temperature adjustment devices is switched between a state in which the heat medium circulates between the device and the first pump, and another state in which the heat medium circulates between the device and the second pump.

Abstract: A refrigeration cycle device includes an air heat exchanger that heats air to be blown into an interior of a vehicle compartment using refrigerant discharged from a compressor, a high-stage side expansion valve decompressing the refrigerant flowing out of the air heat exchanger, and a battery heat exchanger that heats air to be blown to a battery using the refrigerant decompressed by the high-stage side expansion valve. In an air heating-warming up mode of heating the air for the interior and the air for the battery, a refrigerant discharge capacity of the compressor is controlled such that an air temperature for the interior approaches a target air temperature, and an opening degree of the high-stage side expansion valve is controlled such that a battery temperature becomes within a predetermined reference temperature range. A selector switch allows a passenger to select which operation of air conditioning or warming-up is prioritized.

Abstract: A battery temperature regulating device includes batteries, inter-battery passages, and a fluid driving device. The batteries are connected to be capable of energization and arranged in a stacking manner. Each of the inter-battery passages is defined between corresponding adjacent two of the batteries. The fluid driving device is configured to flow temperature regulating fluid for regulating temperature of the batteries through the inter-battery passages. Each of the inter-battery passages includes a first inter-battery passage and a second inter-battery passage. Between the corresponding adjacent two of the batteries, a direction in which temperature regulating fluid flows into the first inter-battery passage and a direction in which temperature regulating fluid flows into the second inter-battery passage are different from each other. A flow direction of temperature regulating fluid flowing through the first inter-battery passage is opposite from a flow direction of temperature regulating fluid flowing through the second inter-battery passage.
