The invention relates to a switching control device for a vehicle-mounted power supply line. The switching control device comprises an ES control chip, a main loop current access end, a redundant loopcurrent access end, an emergency loop current access end, an ES main branch, an ES emergency branch and an ES pre-charging branch. The invention further relates to a switching control method of the vehicle-mounted power supply line. The switching control method comprises the steps that main loop voltage data, main loop current data, redundant loop voltage data, redundant loop current data and emergency loop current data are monitored in real time; a protection mode is set to be an under-voltage protection mode, or an over-voltage protection mode, or a main loop over-current protection mode, or a redundant loop over-current protection mode, or an emergency loop over-current protection mode; monitoring is conducted in real time; when each piece of information is empty, pre-charging protection is conducted; and the switching control device for the vehicle-mounted power supply line is connected. According to the invention, a main loop and a redundant loop can be isolated to ensure continuous normal work; and MOSFET state, connection state recovery, fault diagnosis and data sampling information can be sent at any time, so vehicle state management is facilitated.

    本发明涉及车载供电线路的切换控制装置,包含ES控制芯片、主回路电流接入端、冗余回路电流接入端、应急回路电流接入端、ES主支路、ES应急支路、ES预充电支路。本发明还涉及车载供电线路的切换控制方法,包含步骤:实时监控主回路电压数据、主回路电流数据、冗余回路电压数据、冗余回路电流数据和应急回路电流数据;置为欠压保护模式,或过压保护模式,或主回路过流保护模式,或冗余回路过流保护模式,或应急回路过流保护模式;实时监测;各信息中都为空,预充电保护;接通车载供电线路的切换控制装置。本发明可将主回路和冗余回路隔离,保证继续正常工作;可以随时发送MOSFET状态、恢复接通状态、故障诊断、数据采样信息,便于车辆状态管理。
