Problems solved by technology

[0003] The existing electric vehicle chassis mainly removes the traditional power system such as the engine on the traditional vehicle chassis, and mounts the battery box with the battery on it, and the connection of the single battery in the battery module in the battery box mainly consists of bolt connection and welding. Bolt connection is to screw the single battery to the manifold. This kind of battery module has a large number of manifolds. The positive and negative directions of each single battery have a strict correspondence with the design of the manifold, and the structure is complex. , the installation is difficult, and the maintenance operation is complicated; welding is mainly divided into resistance welding, laser welding and ultrasonic welding. The cost is also high, it is not suitable for production line assembly, and the disassembly and maintenance of the battery module after welding is also inconvenient
