The invention provides an expanded high-voltage battery pack for an electric vehicle. The expanded high-voltage battery pack is arranged in a trunk of the electric vehicle. The electric vehicle comprises a main battery pack, a vehicle body cross beam and a rear floor. A set of lower guide rails are fixed to the top of the rear floor in the length direction of the vehicle body. A group of upper guide rails are detachably mounted at the bottom of the expanded high-voltage battery pack of the electric vehicle, and the group of upper guide rails and the group of lower guide rails are correspondingly arranged and are in sliding connection. A first quick-connection socket is formed in the side wall of the rear end of the vehicle body cross beam, and the inner side of the first quick-connection socket is connected with the main battery pack. The side wall of the front end of the expanded high-voltage battery pack of the electric automobile is provided with a second quick-connection socket, and the outer side of the second quick-connection socket is detachably connected with the outer side of the first quick-connection socket through a high-voltage wire so that electric energy in the expanded high-voltage battery pack of the electric automobile can be provided for the electric automobile. The expanded high-voltage battery pack of the electric automobile can be quickly replaced, and additional endurance mileage can be provided for a pure electric automobile type.
