The invention discloses a low-voltage charging device based on motor multiplexing and a control method, and belongs to the technical field of motor multiplexing low-voltage charging. The device comprises a pre-charging loop module, a BOOST loop module, a charging pile main relay Ks, a direct current charging pile DC and a BUCK loop module; the pre-charging loop module is connected with the BOOST loop module, one end of the DC charging pile DC and the BUCK loop module. The BOOST loop module is connected with the moving end of the charging pile main relay Ks and the BUCK loop module. The fixed end of the charging pile main relay Ks is connected with the other end of the DC charging pile DC. Through the control method of the low-voltage charging device based on motor multiplexing, the low-voltage charging device based on motor multiplexing provided by the invention solves the problem that an electric vehicle direct-current charging economical solution of a low-voltage platform and direct-current charging pile compatibility are lacked at present.
