EV power battery management integrated training system automotive educational equipment

1.1.Product Description

The Power Battery Management Integrated Training System is a teaching application platform that demonstrates the structure of a pure electric vehicle's power battery pack, as well as power battery testing and troubleshooting operations. It showcases components of the pure electric vehicle's power battery system, such as power battery modules, current sensors, main contactors, pre-charge contactors, positive contactors, charging contactors, and battery management systems. The training system simulates the high-voltage energization process of the power battery.
