Battery replacement system

The invention provides a battery replacing system, and relates to the technical field of vehicle new energy. A lifting mechanism of the battery replacing device is used for driving a battery replacing platform to do lifting motion relative to a fixed platform, the lifting mechanism comprises a cross lifting support, a sliding part and a driven part, the two ends of the cross lifting support are connected with the battery replacing platform and the fixed platform respectively, and the sliding part is slidably connected with the fixed platform and provided with a first inclined face extending obliquely and upwards. The inclination angle of the first inclined face is larger than the included angle between the crossed lifting support and the fixed platform when the crossed lifting support is located at the lowest position, the driven piece is connected with the crossed lifting support and makes contact with the first inclined face of the sliding piece, and the driven piece is arranged to move along the first incl
