Battery replacing device and battery switch system of electric passenger vehicle

The utility model relates to a battery replacing device applicable to an electric passenger vehicle. The battery replacing device comprises a cell box rotating disc set, charging rack battery pick-and-place equipment and electric passenger vehicle battery pick-and-place equipment, wherein, the cell box rotating disc set comprises a string of cell box rotating discs, angles of the cell box rotating discs can be pre-set on the basis of the axes rotation of the cell box rotating discs; the charging rack battery pick-and-place equipment is arranged between the cell box rotating disc set and a charging rack; and the electric passenger vehicle battery pick-and-place equipment is arranged between the electric passenger vehicle and the cell box rotating disc set. The utility model further relates to a battery switch system including the battery replacing device. The battery replacing device utilizes two kinds of battery pick-and-place devices to be matched with the cell box rotating discs, so that the replacement of a cell box of the electric passenger vehicle is more smooth. The entire battery replacement process is smooth, the replacement time is short, and since the battery replacement efficiency is improved, more times of battery replacement can be completed within a unit time, and the battery replacement cycle is shorter, so that a battery charger can more adequately charge, and the utilization ratio is higher.
