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

摘要

PROBLEM TO BE SOLVED: To accurately carry out offset learning of a current sensor during external charging in an externally chargeable vehicle.

SOLUTION: A vehicle 10 is configured to be able to charge an energy storage device 12 using an external power supply outside the vehicle. A charger 24 receives electric power supplied from the external power supply to charge the energy storage device 12. A current sensor 28 detects a current IB input to or output from the energy storage device 12. During external charging, when the charger 24 and the auxiliary load 20 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 28 is satisfied, the controller 26 carries out offset learning of the current sensor 28.
