Battery production process
Its production includes two aspects: installation and testing.
1. Thermal pad and water pipe installation
2. Module installation
3. Air tightness test of water cooling system
The air tightness of the water cooling system is tested by pressurizing and maintaining pressure.
4. High and low voltage wiring harness installation
5. High voltage insulation test 6. Flame retardant heat insulation protective layer installation
Further reduce the risk of thermal runaway.
7. Top cover installation 8. Pack air tightness test
9. EOL offline testing
10. Power battery off the production line
The structure of a power battery may seem simple, but to improve performance, safety, and lifespan, there are many ingenious designs involved!
1. Battery Management System BMS
2. Flame retardant and heat insulation protective layer
3. Thermal management system
4. High voltage wiring harness
The high-voltage wiring harness is an essential component for realizing the electrification architecture. It can realize the series or parallel connection of modules, making the design and layout of modules and battery packs more flexible. In conjunction with the relay in the EDM, it can also realize the switching of the battery pack voltage platform according to demand.
5. Integrated casting
