Abstract

A battery electric vehicle includes a battery, an inverter having three arm circuits, a motor having three coils connected to a neutral point and three arm circuits, a relay, a ground wire, and a controller. The controller can selectively perform a normal charging operation and a heat generation charging operation. In normal charging operation, equal current flows in all three coils in the positive direction from the neutral point to the arm circuit. In the heat generation charging operation, a first current flows in the positive direction in at least one of the three coils, and a second current flows in the opposite direction from the arm circuit toward the neutral point in the other coils. The total value of the first currents is greater than the total value of the second currents.
