Abstract

The embodiments of the present application provide a low-voltage power transmission system, a DCDC converter and a control method, a device and a medium, relating to the field of battery power. The control method includes: acquiring a charging signal; acquiring a vehicle start signal; acquiring an enabling signal; when each of the charging signal, the vehicle activating start signal, and the enabling signal is at a low level, and no communication message sent by a battery management system (BMS) is received, determining that a vehicle is in a power-off state and enters a sleep mode; when a duration of the sleep mode reaches a preset duration, performing self-awakening, and outputting, to the BMS, an awakening signal for awakening the BMS and making the BMS enter a working mode.
