Problems solved by technology
The traditional electric vehicle chassis is mainly connected by bolts and welded to install the battery cells. The copper nuts of the positive pole of the battery and the copper bolts of the negative pole of the battery are connected to each other and fixed on the copper plate for confluence. The internal monitoring circuit and the modules are connected by wires. Confluence design, high requirements on welding level and bolt surface quality, many battery lines, complex wiring, bolts are easy to fall off during long-term operation, poor line reliability, complicated line installation, inconvenient maintenance, heavy copper bolts and copper plate confluence, Not conducive to the lightweight of the vehicle
