GCE BMS features:


1.From kWh to GWh, GCE Energy High-Voltage BMS manages up to 1000 VDC per battery stack and no limit stacks in parallel with the addition of a Multi Stack Controller.
2.Connects and disconnects a battery stack to the DC Bus of the ESS in response to requests from system controllers. Will also report the resulting capacity change to the PCS and other energy management systems.

3.Atomatically Measures cell- and stack-level voltage, temperature, and current. Calculates State of Charge (SOC), and Depth of Discharge (DOD) and provides this information to the PCS to enable precise charge/discharge control.

4.Provides battery information thresholds to the PCS/inverters, triggers warnings when approaching safety limits, can activate battery cooling fans.and this is editable according to customer's request.

5.Alter current limits to protect the battery from overcharge and over-discharge as well as to reduce battery temperature and to prevent over-voltage.

6.pre-charge circuit when connecting the stack to the DC bus, to prevent current surges and voltage mismatches that could damage cells.

Disconnects batteries from the power path if safety thresholds are exceeded during ESS/UPS operation.

7.short-circuit protection is necessary

8.Advanced battery management system---The highly integrated battery management system can realize seamless monitoring.

9.Perfect self-checking and running status checking function, with HMI display screen,system running information is clear at a glance.

10. Complete and reliable system control and protection strategies, comprehensively guarantee battery safety, and escort to extend the life of battery packs.

11.Modular design, configurable and expandable---multiple energy storage units can be flexibly combined and expanded into a larger energy storage system.

12.Rich communication interfaces---multiple RS485, CAN, Ethernet, dry contact input and output interfaces, supporting communication with most PCS and monitoring servers on the market.

13. The communication interface protocol is flexible---the factory comes with the company's communication protocol, and it can also be adapted to the PCS of different manufacturers according to customer needs.

14.Automatic circulation control and automatic parallel/offline control can easily realize the parallel connection of battery packs.
