The present disclosure provides a system and method for selecting a battery pack for pre-charging a high voltage DC bus of an electric vehicle. Disclosed is a cycle structure that prevents repeated selection of a battery pack to prevent burnout of a resistor of the battery pack due to a rapid subsequent pre-charge event. The systems and methods provided include an easy solution that is scalable to a system having any number of battery packs, does not require any additional hardware, and is an inexpensive technology to protect expensive components of an electric vehicle.

    本公开提供了一种用于选择用于对电动车辆的高压DC总线进行预充电的电池组的系统和方法。公开了一种防止重复选择电池组以防止由快速后续预充电事件导致的电池组的电阻器烧毁的循环结构。所提供的系统和方法包括容易的解决方案,该解决方案可扩展到具有任何数量的电池组的系统,不需要任何额外的硬件,并且是保护电动车辆的昂贵组件的廉价技术。
