1. Advanced Battery Management System --- The highly integrated battery management
system enables seamless monitoring.
2. perfect self-test and operational status detection, with HMI display, system
operation information at a glance.
3. perfect and reliable system control and protection strategies to fully protect the
battery safety, and extend the life of the battery escort.
4. Modular design, configurable, scalable --- flexible combination of multiple energy
storage units can be expanded to a larger energy storage system, the maximum can support 272 (lead-carbon battery 400) battery
5. Rich communication interface --- multiple RS485, CAN, Ethernet, dry contact input and
output interfaces, support for most of the market with PCS, monitoring server communication.
6. Flexible communication interface protocol --- The company comes with the company's
communication protocol, but also according to customer needs to adapt to PCS of different manufacturers.
7. Capacity is large --- Built-in large-capacity memory chips can store a large number
of key operational data, but also can install an SD card for offline access.
8. PCS has a protocol control function, the choice of circuit breaker version.

10. Automatic circulation control and automatic parallel machine off-line control, can be easily parallel batteries. (Model suffix selection D).
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 batteries. 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.
