The structure of the power battery seems simple, but there are many ingenious designs to improve performance, safety, and lifespan!
Its production includes two aspects of installation and testing.
1. Installation
1. Thermal pad, water pipe installation
2. Module installation

4. High voltage wiring harness
High voltage wiring harnesses are an integral part of enabling an electrified architecture. It can realize modules connected in series or in parallel, which makes the design and layout of modules and battery packs more flexible. Cooperating with the relay in the EDM, it is also possible to switch the voltage platform of the battery pack according to the demand.
5. Integrated casting molding
