The invention relates to a method for quickly charging a low-voltage battery platform of a pure electric vehicle, which comprises an alternating-current input EMI (Electro-Magnetic Interference) filter circuit, a bridgeless PFC (Power Factor Correction) circuit, a direct-current charging interface circuit, a pre-stage filter circuit, a DC/DC (Direct Current/Direct Current) conversion circuit, a post-stage rectification filter circuit and a main control chip control and communication circuit, and is used for carrying out alternating-current charging or direct-current charging. By upgrading the function of the vehicle-mounted charger on the miniature electric vehicle, the output power of the miniature electric vehicle is increased, and the problem that the miniature electric vehicle uses a direct-current charging pile for rapid charging is solved. And the direct-current charging circuit interface receives the direct current with the fixed voltage value output by the direct-current charging pile and internally converts the direct current into low-voltage power to charge the low-voltage power battery pack.
