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. The low-voltage power transmission system, the DCDC converter, the control method, the device, and the medium according to the embodiments of the present application can improve the safety of the battery pack.
