Abstract
A converter includes one chip constituted a switching device and a diode. An electronic control unit is configured to calculate a temperature estimated value of the switching device from control conditions of the converter, restrict a control upper-limit value of charge power or discharge power of a battery, when a detection value of a temperature sensor is higher than the temperature estimated value of the switching device, and the detection value of the temperature sensor exceeds a protection temperature of the diode, and restrict a control upper-limit value of charge power or discharge power of the battery, when the detection value of the temperature sensor is lower than the temperature estimated value of the switching device, and the detection value of the temperature sensor exceeds a protection temperature of the switching device.
