Abstract

A battery temperature control system includes a battery temperature control circuit, a high temperature refrigerant circuit radiating heat from a refrigerant, a low temperature refrigerant circuit absorbing heat into the refrigerant, a refrigeration cycle circuit used for an air conditioner of the vehicle, a first valve mechanism switching between a high connection state where the battery temperature control circuit and the high temperature refrigerant circuit communicate with each other and a high disconnection state where those circuits are disconnected, a second valve mechanism switching between a low connection state where the battery temperature control circuit and the low temperature refrigerant circuit communicate with each other and a low disconnection state where those circuits are disconnected, a first heat exchanger transferring heat from the low temperature refrigerant circuit to the refrigeration cycle circuit, and a second heat exchanger transferring heat from the refrigeration cycle circuit to the high temperature refrigerant circuit.
