Abstract
An electric vehicle automatic charging system includes an electric vehicle including a receiving cavity with an opening and a shutter for closing the opening, a battery assembly receiving in the receiving cavity and a charging device. The battery assembly includes a battery pack including an electrode connecting member and a movable bracket including a magnetic member. The charging device includes a support table, a support plate, an electromagnetic fitting member being capable of generating a magnetic force for attracting the magnetic member, and a charger. When the shutter comes into contact with the support plate, the shutter changes from a closed state to an open state, the movable bracket drives the battery pack to move away from the receiving cavity along the support plate by the magnetic force until the electrode connecting member is electrically connected to the charger. An electric vehicle automatic charging method is also provided.
