ON-BOARD DISTRIBUTED POWER SUPPLY SYSTEM AND ON-BOARD POWER SUPPLY CONTROL METHOD AND APPARATUS

This application provides an on-board distributed power supply system and an on-board power supply control method and apparatus. The on-board distributed power supply system includes at least two low-voltage battery pack groups. Each low-voltage battery pack group includes at least one low-voltage battery pack. Each low-voltage battery pack includes a plurality of battery cells. Each low-voltage battery pack group is correspondingly electrically connected to at least one power train in an on-board distributed drive system to provide electric energy for each power train in the on-board distributed drive system. In embodiments of this application, power is supplied to the on-board distributed drive system by using at least two low-voltage battery pack groups. When some low-voltage battery pack groups are faulty, remaining low-voltage battery pack groups may continue to work. Therefore, this can avoid a failure of the entire power supply system and improve power supply reliability and safety of the power supply system.
