The disclosure provides a system and a method for charge contactor weld check. A power distribution system for a vehicle includes contactors that selectively electrically couple a charger to a high-voltage bus. The contactors are closed at the start of a charge event in an order that alternates for successive charge events. Upon completion of the charge event, the last closed contactor at the start of the charge event is opened first and a weld check is performed. If the weld check is indicative of a welded contactor, then the weld check is performed on the other contactor.

    本公开提供“用于充电接触器焊接检查的系统和方法”。一种用于车辆的配电系统包括接触器,所述接触器将充电器选择性地电耦合到高压总线。所述接触器在充电事件开始时以交替用于连续的充电事件的顺序闭合。在完成所述充电事件后,在所述充电事件开始时最后闭合的所述接触器第一个断开并且执行焊接检查。如果所述焊接检查指示焊接接触器,则对另一个接触器执行所述焊接检查。
