BATTERY REPLACEMENT ROBOT WITH MOBILE STORAGE RACK AND BATTERY REPLACEMENT METHOD

A battery replacement robot (1) with a mobile storage rack and a battery replacement method. The battery replacement robot (1) comprises a mechanical part and an electrical control part. The electrical control part controls a battery replacement device to place, in one step, all battery boxes required by one side of an electric bus (3) that needs battery replacement onto a battery box storage rack (12). A horizontal moving unit (101) moves to a position where a battery needs to be replaced. A battery box replacement device takes down a spent battery box from the electric bus (3); the battery box replacement device rotates towards one side around a Y axis, and raises or lowers the spent battery box so as to put the spent battery on the battery box storage rack (12); then the battery box replacement device takes down a charged battery box from the battery box storage rack (12), rotates to the original position, and installs the battery box in the electric bus (3). This operation is repeated to complete the battery box replacement on the electric bus (3). Battery boxes required by one side of an electric bus are prepared in one step, which avoids long-distance and repeated operations of the battery replacement robot in a large space. The structure is simple, the battery replacement time is reduced, space occupied by a working area is reduced, and the utilization of land resources is effectively improved.
