CHARGING DEVICE FOR VEHICLE, VEHICLE EQUIPPED WITH CHARGING DEVICE, AND OFFSET CORRECTION METHOD FOR CURRENT SENSOR

摘要

A vehicle is configured to be able to charge an electrical storage device using an external power supply outside the vehicle. A charger receives electric power supplied from the external power supply to charge the electrical storage device. A current sensor detects a current input to or output from the electrical storage device. During external charging, when the charger and the auxiliary load are turned off and a determination condition for determining that the current (IB) is zero on the basis of the value detected by the current sensor is satisfied, the controller carries out offset learning of the current sensor.
