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.
