Company introduction:

Hunan Group Control Energy Technology Co., Ltd.(GCE) is a high-tech company specializing in the research and development of BMS and lithium battery peripheral equipment. The high-performance intelligent lithium battery management system produced by our company adopts the international leading technology, which greatly improves the battery management efficiency and prolongs the service life of lithium battery. The advanced BMS control strategy avoids the difficulties and instability faced by most competitors for our BMS.

We mainly have two BMS Categories, both applicable to Lifepo4 batteries, MnNiCo ternary batteries,

Lithium Titanate batteries.


The 30s to 75s BMS adopts a master-slave integrated design and relay solution to meet the lithium battery demand of multiple strings of small capacity batteries. Greatly reduce the use cost of users; 60s-270s adopts master-slave three-level architecture, which can meet the series and parallel requirements of high-capacity single lithium batteries within 1000V.

By mastering the core technology of BMS and inventing on this basis, our company has developed a variety of lithium battery peripherals to meet the high-quality needs of the market.
