GCE Series HV-BMS products are battery management systems developed for large-scale high-voltage battery energy storage systems. It adopts distributed architecture, modular design concept, high configurability, easy assembly, debugging and maintenance. It is suitable for various battery energy storage systems with DC voltage below 1000V. This product can be configured as a secondary architecture (BMU+RBMS) for 10KWh-500KWh. Cooperate with industrial computer and battery stack management software to form a three-level architecture (BMU+RBMS+SBMS) for 50KWh-2MWh applications. In conjunction with the server and plant battery management system software, it can form a four-level architecture (BMU+RBMS+SBMS+BBMS) for applications from 2MWh to 1000MWh to meet different project requirements.

GCE HV- BMS for Lifepo3,NMC,LTO battery packs applications:

1. BESS / solar farm

2. UPS (uninterpretable power supply)

3. power grid energy storage/ Microgrid power

4.Urban rail train

5. charging pile station energy storage

GCE HV-BMS features:

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.

working in the factory:

 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.

4S to 24s low voltage software BMS has a wide range of uses, rich product interfaces, strong scalability and secondary development compatibility; 30s to 75s BMS adopts 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.
