GCE high voltage BMS features:


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

Perfect self-checking and running status checking function, with HMI display screen,3.5inch and 7 inch touch screen optional .system running information is clear at a glance.

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

Modular design, configurable and expandable-----multiple energy storage units can be

flexibly combined and expanded into 1GWh as a larger energy storage system.


Abundant communication interfaces---multiple RS485, CAN, Ethernet, dry contact input

and output interfaces, supporting communication with most PCS/inverter and monitoring servers in the market.


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.

7 The built-in large-capacity memory chip can store a large amount of key operating data, and an SD card can be added to realize battery historical data storage

Automatic circulation control and automatic parallel/offline control can easily realize the

parallel connection of battery packs.
