More specifically, front and rear sensors may be mounted at the front and rear ends of the RGV102, respectively. The front side sensor and the rear side sensor can adopt laser sensors to ensure detection accuracy.

Wherein, rear wheel fine adjustment mechanism 105 supports in rear wheel centering roll table 104 below. The control component of the rear wheel fine adjustment mechanism 105 is communicatively connected with the front side sensor and the rear side sensor to fine adjust the rear side height of the electric vehicle based on the front side sensor and the rear side sensor detection data. More specifically, when the rear side height of the battery-change vehicle is lower than the front side height, the rear wheel fine adjustment mechanism 105 adjusts the rear wheel centering roller table 104, and when the rear side height of the battery-change vehicle is higher than the front side height, the rear wheel fine adjustment mechanism 105 adjusts the rear wheel centering roller table 104. The rear wheel fine adjustment mechanism 105 may employ an electric motor or a hydraulic cylinder.

The power exchange station combines the detection data of the front side sensor and the rear side sensor, and utilizes the rear wheel fine adjustment mechanism 105 to finely adjust the height of the rear wheel centering roller way 104, so that the rear side height of the power exchange vehicle is changed until the rear side height of the power exchange vehicle is consistent with the front side height, the purpose of leveling the power exchange vehicle is achieved, and compared with the traditional leveling mode by lifting the power exchange vehicle, the leveling speed is higher, the power exchange beat can be accelerated, and the power exchange efficiency is improved.

In a specific embodiment, as shown in fig. 1, a first opening 106a, a second opening 106b and a third opening 106c are sequentially provided on the parking platform 106 from front to back, the front wheel alignment roller way 103 is exposed from the first opening 106a, the RGV102 is exposed from the second opening 106b, the rear wheel alignment roller way 104 is exposed from the third opening 106c, and the second opening 106b is not provided with an opening door.

The arrangement can effectively prevent the spread of fire after fire in each area while fully utilizing the internal space of the charging container B, so that the power exchange station has higher safety. More specifically, the personnel attendant room 207 may be provided with an observation window, so as to observe the external condition of the power exchange station in real time, thereby further improving the safety of the power exchange station. More specifically, the personnel duty room 207 may be equipped with a manual starting device, a deflation no-entry indicator light, an audible and visual alarm, etc. for external emergency starting and warning, so as to further improve the safety of the power exchange station. More specifically, sliding doors may be provided between the charging cabinet 205, the PLC control cabinet 206, the personnel attendant room 207, and the battery access unit, to facilitate inter-area observation and access maintenance operations.

In one embodiment, as shown in FIG. 4, the power plant includes a fire module 400. The fire module 400 comprises a fire detector 401 and gas fire-fighting equipment, and the fire detector 401 can be a smoke detector or a composite detector.
