[0002] In recent years, with the worsening environmental degradation, the new energy electric vehicle industry has shown great development potential, the new energy market has risen rapidly, and new energy trucks have gradually entered the public eye. In the traditional automobile industry, most OEMs adopt a modular approach to purchase parts from component suppliers and then assemble them. The main difference between new energy trucks and traditional vehicles is that they use electric power instead of fuel engines. With the development of new energy technology, on-board chargers (OBC) and high-voltage distribution boxes (PDU) have become essential modules for new energy trucks.

[0003] Currently, people's demands for new energy vehicles are increasing. However, charging infrastructure is still inadequate, and the concentrated charging population leads to excessively long charging wait times. Against this backdrop, battery swapping technology has emerged. With its unique advantages, it can complete battery replacement in minutes, allowing vehicles with depleted power to be used quickly, significantly reducing waiting time and meeting the needs of a fast-paced lifestyle.

[0004] However, in practical applications, there are many technical challenges, such as the compatibility between the battery swapping device and the truck's structure, how to efficiently supply vehicle energy to various electrical devices at the rear end of the vehicle, and the dustproof and waterproofing issues of the battery swapping device's casing, all of which urgently need to be addressed.
