Power control apparatus for vehicle
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.
1 . A power control apparatus for a vehicle, comprising:
a battery that supplies power to a drive unit of a vehicle;
a current sensor that detects electrical current of the battery;
a temperature sensor that detects temperature of the battery;
a cutoff element that cuts off a flow of electrical current from the battery and a flow of electrical current to the battery; and
a controller that, when a current detection function of 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 cutoff element to cut off the flow of electrical current from the battery and the flow of electrical current to the battery.
2 . The power control apparatus for a vehicle according to claim 1 , further comprising a cooler that cools the battery,
wherein the predetermined period of time is set based on a heat generation characteristic of the battery and a cooling characteristic of the cooler.
