The invention relates to a magnetically coupled charging system and method. The magnetically coupled charging system comprises: a resonant inverter; a split core transformer configured to receive a resonant power from the resonant inverter; and a rectifier assembly configured to receive a transformed resonant power from the split core transformer and transmit the transformed resonant power to a to-be-charged battery; the split core transformer comprising a primary winding and a secondary winding, wherein the primary and secondary windings are split from each other, the resonant inverter and the primary winding of the split core transformer are arranged in an onshore charging system, the rectifier assembly and the secondary winding of the split core transformer are arranged in an onboard charger. The invention has the following advantages of: eliminating the risk of electric shock and short circuit fault at a connection point and eliminating an arcing or sparking problem.
