AI Technical Summary

Technical Problem

Existing energy storage battery management systems suffer from slow response speed, low accuracy, and poor safety in power control, failing to meet the grid's rapid frequency regulation requirements. Furthermore, the lack of multi-level safety protection mechanisms leads to poor battery consistency and shortened lifespan.

Method used

A power control circuit is adopted, including a main control chip, a battery cluster-level contactor control circuit and a precharge contactor control circuit, combined with a fuse protection circuit and a status monitoring circuit. Fast response and precise control are achieved through optocouplers and Darlington arrays, and real-time calculation and protection are performed in conjunction with a coprocessor.

Benefits of technology

It achieves millisecond-level fast power response capability, significantly improves the grid frequency regulation capability of energy storage system, extends battery life, and ensures safe and reliable system operation through multi-level protection mechanisms.
