Vehicle-mounted storage battery power supply control circuit and vehicle

The utility model discloses a vehicle-mounted storage battery power supply control circuit and a vehicle, and the circuit comprises a detection unit which is used for detecting the opening and closing state of each vehicle door and the starting and stopping state of an engine, and outputting a timing starting signal when each vehicle door is in a closed state and the engine is in a shutdown state; the timing unit is used for starting timing when the timing starting signal is received and outputting a disconnection signal when the timing duration reaches a preset threshold value; the switch unit is used for enabling the vehicle-mounted storage battery to stop supplying power to the preset whole vehicle load when receiving the disconnection signal, and actively cutting off the power supply of the vehicle-mounted storage battery to the preset whole vehicle load when the vehicle is in a long-time parking state, so that the power supply control on the vehicle-mounted storage battery is automatically realized, the
