Abstract
An onboard-battery temperature controller to be disposed inside a vehicle, near a battery including a plurality of battery cells, is configured to control the temperature of the battery cells. The onboard-battery temperature controller includes a fluid heater, a heat generating body, and an arithmetic and control unit. The fluid heater is configured to heat the battery cells through heat exchange between a heating fluid circulating therein and the battery cells. The heat generating body is configured to be energized and generate heat, to be conducted to the battery cells to heat the battery cells. The arithmetic and control unit is configured to control operations of the fluid heater and the heat generating body on the basis of the temperature of the battery.
