The disclosure provides a battery temperature control device of an electric vehicle capable of efficiently heating a battery for vehicle driving while executing V2G in a low temperature environment. A battery temperature control device of an electric vehicle controls the temperature of a battery of the electric vehicle, and the electric vehicle participates in V2G which allows bidirectional power exchange between the battery for vehicle driving mounted on the electric vehicle and a power system. When an aggregator on the power system side starts execution of V2G by transmitting to an ECU a start instruction for the charge and discharge of the battery, the ECU controls a four-way valve to connect a battery cooling circuit and a charger cooling circuit when a battery temperature is less than a predetermined temperature.
