Abstract
An IPU for a vehicle includes a battery that supplies power to a drive unit of a vehicle, a current sensor that detects current of the battery, a temperature sensor that detects temperature of the battery, contactors that cut off the flow of electrical current from the battery and the flow of electrical current to the battery, and a battery ECU that, when a current detection function by the current sensor has been lost, measures a period of time for which a temperature detected by the temperature sensor reaches a second predetermined value from a first predetermined value and, when the measured period of time is less than a predetermined period of time, operates the contactors to cut off the flow of electrical current from the battery and the flow of electrical current to the battery.
