A power supply system for a vehicle and a method thereof are disclosed. The system 100 comprises a high voltage (HV) battery pack 106, a battery management system (BMS) 102 connected to the HV battery pack 106, a battery disconnect unit (BDU) 108 comprising a high power contactor 110 connecting the HV battery pack 106 to a plurality of HV loads 122, characterized in that the BDU 108 comprises a low power contactor 120. A low power contactor 120 connects the HV battery pack 106 to a plurality of low voltage (LV) loads 124 through a DC-DC converter 112. Power supply systems 100 and methods provide particular designs and solutions to eliminate LV battery from an electric vehicle (EV) and to supply LV power through the HV battery pack 106 itself. The system 100 and corresponding operating strategies for the BDU 108, the DC-DC converter 112, and the BMS 102 replace the LV battery.
公开了用于车辆的电源系统及其方法。系统100包括高电压(HV)电池组106、连接到HV电池组106的电池管理系统(BMS)102、包括将HV电池组106连接到多个HV负载122的高功率接触器110的电池断连单元(BDU)108,其特征在于,BDU 108包括低功率接触器120。低功率接触器120通过DC‑DC转换器112将HV电池组106连接到多个低电压(LV)负载124。电源系统100和方法提供了用以从电动车辆(EV)消除LV电池并且通过HV电池组106本身供给LV功率的特定的设计和解决方案。系统100和用于BDU 108、DC‑DC转换器112和BMS 102的对应操作策略取代了LV电池。
