The invention discloses a power supply system of a power chassis domain and a related method, redundant power supply is realized through a high-low voltage power conversion unit, a buck-boost power conversion unit and a redundant input switching unit, the power supply stability of the power chassis domain can be ensured under the condition of voltage fluctuation or fault of a low-voltage battery, and the reliability of the power chassis domain is improved. And the output monitoring and management unit is also arranged, so that when the power utilization of the controller fails, the power supply of the failed power utilization controller can be cut off and isolated, and the failed power utilization controller is effectively prevented from influencing other controllers.

    本发明公开了一种动力底盘域的供电系统及相关方法,本发明通过高低压功率变换单元、升降压功率变换单元和冗余输入切换单元实现了冗余供电,在低压电池电压波动或故障情况下,也可保证动力底盘域的供电稳定,并且本发明还设置了输出监控与管理单元,在控制器用电故障时,可对故障用电控制器进行供电切断和隔离,有效防止故障用电控制器影响其他控制器。
