According to the new energy automobile battery replacing device, when a to-be-replaced vehicle 12 drives into the vehicle battery replacing station 11, the positioning device ensures that the vehicle is aligned with the rail guided trolley 41. Subsequently, the lifting assembly 60 on the track guided vehicle 41 is raised and drives the locking and unlocking mechanism to be raised to unlock the battery pack 50 of the vehicle, and the battery pack 50 after unlocking is dropped onto the lifting platform 61 and is lowered along with the lifting platform 61. Subsequently, the control device controls the rail guided vehicle 41 to transport the battery pack 50 to be charged to the battery pack exchange station 21 according to the current position of the cavity detected by the sensor. Meanwhile, the control device controls a driving component corresponding to the storage rack 70 with the cavity to drive the storage rack 70 to slide right above the rail guided trolley 41, so that the rail guided trolley 41 is aligned and then the battery pack 50 to be charged is placed in the cavity through the lifting component 60 and the locking and unlocking mechanism. Subsequently, the driving assembly drives the current storage rack 70 to reset, and charges the battery pack 50 to be charged by a charging device (not shown). After the guided vehicle 41 on the rail unloads the battery pack 50 to be charged, the control device controls the driving assembly corresponding to the storage rack 70 where the fully charged battery pack 50 is located to drive the storage rack 70 to move to the battery pack exchange station 21 according to the position of the fully charged battery pack 50 detected by the sensor, and the lifting assembly 60 resets. If the front rail guided vehicle 41 is located just below the moving storage rack 70, the fully charged battery pack 50 is removed by the lifting assembly 60 and the locking and unlocking mechanism and then placed on the lifting platform 61. If the current rail guided vehicle 41 is not positioned right below the moving storage rack 70, the control device controls the rail guided vehicle 41 to move right below the storage rack 70, and then the fully charged battery pack 50 is detached through the lifting assembly 60 and the locking and unlocking mechanism and then placed on the lifting platform 61.
