The invention relates to an electric vehicle low-voltage battery charging control system which comprises a vehicle-mounted controller, an electric control switch, a low-voltage battery, a battery management system and a vehicle charging interface, wherein the vehicle-mounted controller is connected with the low-voltage battery in series through the electric control switch, and the vehicle-mounted controller is connected with the battery management system in series. The battery management system is in communication connection with the electric control switch and the low-voltage battery. The vehicle charging interface is used for being electrically connected with external power supply equipment. The vehicle charging interface comprises an A+ interface, an A-interface, an S+ interface and an S- interface which are electrically connected with the vehicle-mounted controller respectively; the power supply equipment comprises a power supply controller, a first connector terminal matched with the A+ interface, a second connector terminal matched with the A-interface, a third connector terminal matched with the S+ interface and a fourth connector terminal matched with the S- interface. The power supply controller is electrically connected with the first connector terminal, the second connector terminal, the third connector terminal and the fourth connector terminal. The low-voltage battery with insufficient power can be simply and conveniently charged.
