The invention discloses an electric automobile and a high-voltage protection device thereof. The high-voltage protection device comprises a battery protection shell, wherein an opening of the battery protection shell is fixedly connected with an aluminum seat; the aluminum seat is fixedly connected with a base; an oscillating bar type travel switch is mounted on the base; a protection cover is detachably mounted on the aluminum seat; when the protection cover is mounted on the aluminum seat, the oscillating bar type travel switch is closed to connect a high-voltage loop; when the protection cover and the aluminum seat is separated from the aluminum seat, the oscillating bar type travel switch is flicked off to disconnect the high-voltage loop; the protection cover is detachably and fixedly connected with a battery upper cover through a connection piece. Therefore, as the protection cover presses the battery cover, and is detachably connected with the battery upper cover, the battery upper cover can be only detached after the protection cover is detached, and the danger of electric shock caused by independent detaching of the battery upper cover is avoided; the mounting protection reliability is improved, and a potential safety hazard is reduced.
