Abstract
An IPU includes a battery that supplies power to a drive unit of a vehicle, a temperature sensor that detects temperature of the battery, a current sensor that detects electrical current of the battery, a voltage sensor that detects voltage of the battery, contactors that cut off the electrical current flow from the battery and the electrical current flow to the battery, and a battery ECU that, when a temperature detection function by the temperature sensor has been lost, calculates a value of the power of the battery based on a detection result of the electrical current and a detection result of the voltage, and operates the contactors when a calculated value of the power exceeds a predetermined value for a predetermined period of time to cut off the electrical current flow from the battery and the electrical current flow to the battery.
