The invention discloses an electric automobile charging system, an electric automobile and an automobile charging control method. The electric vehicle charging system comprises: a linked switch whichcomprises at least one first switch and at least one second switch, and the states of the first switch and the second switch are opposite; a high-voltage battery; a high-voltage distribution box, wherein the battery connecting end of the high-voltage distribution box is electrically connected with the high-voltage battery; a vehicle-mounted charger, wherein the output end of the vehicle-mounted charger is electrically connected with the vehicle-mounted charger connecting end of the high-voltage distribution box; an alternating current charging interface which is used for being electrically connected with an alternating current power supply, and the alternating current charging interface is electrically connected with the input end of the vehicle-mounted charger through a first switch; anda direct-current charging interface which is electrically connected with the direct-current charging connecting end of the high-voltage distribution box through a second switch, wherein the direct-current charging interface is used for being electrically connected with a direct-current power supply. The situation that two charging modes of direct-current charging and alternating-current charging occur at the same time is avoided, the safety of the high-voltage battery is protected, and then the charging safety of the electric automobile is improved.
