The invention relates to a battery electric vehicle. A battery electric vehicle is provided with: a battery; the inverter is provided with three bridge arm circuits; a motor having three coils electrically connected to the neutral point and the three legs; a relay; a ground wire; and a controller. The controller is capable of selectively performing a normal charging action and a hot charging action. In a normal charging operation, in all the three coils, an equal current flows in a forward direction from the neutral point to the leg circuit. In the thermal charging operation, a first current flows in the forward direction in at least one of the three coils, and a second current flows in the reverse direction from the arm circuit toward the neutral point in the other coils. The total value of the first current is greater than the total value of the second current.

    本发明涉及电池电动汽车。电池电动汽车具备:电池;逆变器,具有三个桥臂电路;马达,具有与中性点和三个桥臂电路连接的三个线圈;继电器;接地线;以及控制器。控制器能够选择性地执行通常充电动作和创热充电动作。在通常充电动作中,在全部的三个线圈中,相等的电流向从中性点朝向桥臂电路的正向流动。在创热充电动作中,在三个线圈中的至少一个线圈中第1电流向正向流动,在其他线圈中,第2电流向从桥臂电路朝向中性点的反向流动。第1电流的合计值比第2电流的合计值大。
