Abstract

A battery-temperature raising apparatus includes a battery, a transmission, an oil pan, a heat-retaining oil tank, a heat exchanger, a first valve, a temperature sensor, and a control unit. The transmission includes a transmission mechanism that converts torque and a clutch capable of braking a wheel. The oil pan and the oil tank are disposed in the transmission and are in communication with the heat exchanger that exchanges heat between the battery and oil. The first valve opens and closes a path joining the oil tank and the heat exchanger. The control unit generates braking force by controlling engagement force of the clutch depending on an amount of depression of a brake pedal. The control unit supplies the oil stored in the oil tank to the heat exchanger by opening the first valve when a temperature of the battery detected by the temperature sensor is below a predetermined temperature.
