Abstract: A drive train for an electric vehicle includes a traction battery, a power drive circuit, a main contactor for connecting and disconnecting the traction battery and the power drive circuit, a voltage detector across contacts of the main contactor, and a controller for controlling the main contactor to prevent movement of its contacts to the closed position when the voltage across the contacts exceeds a predetermined threshold, to thereby protect the contacts of the contactor. The power drive circuit includes an electric traction motor and a DC-to-AC inverter with a capacitive input filter. The controller also inhibits the power drive circuit from driving the motor and thereby discharging the input capacitor if the contacts are inadvertently opened during motoring. A precharging contactor is controlled to charge the input filter capacitor prior to closing the main contactor to further protect the contacts of the main contactor.
Abstract translation: 一种用于电动车辆的传动系包括牵引电池，动力驱动电路，用于连接和断开牵引电池和电力驱动电路的主接触器，在主接触器的触头上的电压检测器，以及用于控制主电动机的控制器 接触器，以防止触头上的电压超过预定阈值时，其触点移动到闭合位置，从而保护接触器的触头。 电力驱动电路包括电力牵引电动机和具有电容性输入滤波器的DC-AC逆变器。 如果触头在电动过程中意外打开，控制器也会禁止驱动电机驱动电机，从而对输入电容器进行放电。 控制预充电接触器在关闭主接触器之前对输入滤波电容器充电，以进一步保护主接触器的触点。
