The present disclosure provides "pre-charging via a bi-directional DC/DC converter and an auxiliary battery". A power control apparatus for a vehicle includes a bidirectional DC/DC converter and one or more controllers. After a request to activate the vehicle, a resistor connected in parallel with one of the main contactors is not connected and before all of the main contactors are closed. The one or more controllers command the bidirectional DC/DC converter to charge a DC side capacitor electrically between the main contactor and the bidirectional DC/DC converter to a target value.
本公开提供“经由双向DC/DC转换器和辅助电池进行预充电”。一种用于车辆的电力控制装置包括双向DC/DC转换器和一个或多个控制器。在激活所述车辆的请求之后,在不连接与主接触器中的一个并联的电阻器的情况下并且在闭合所有所述主接触器之前,所述一个或多个控制器命令所述双向DC/DC转换器将电气地介于所述主接触器与所述双向DC/DC转换器之间的直流侧电容器充电到目标值。
