BMS Features：

• Advanced battery management system — highlyintegrated battery management system can realize seamless monitoring.

• Perfect self inspection and operation status detection function, combined with HMI display screen, the system operation information is clear at a glance.

• Perfect and reliable system control and protection strategies to fully ensure the safety of the battery andescort the extension of the service life of the battery pack.

• Modular design, configurable and expandable — multiple energy storage units can be flexibly combined toexpand into a larger energy storage system, and can support up to 200 batteries in series.

• Rich communication interfaces — RS485, CAN, Ethernet, dry contact input and output interfaces,supporting communication with most PCS/Inverter/UPS and monitoring servers on the market.

• Flexible communication interface protocol — the factory comes with the company’s communicationprotocol, and PCS / Inverter / UPS of different manufacturers can also be adapted according to customer needs.

• Great capacity data memory — the built-inhigh-capacity memory chip can store a large number of key operation data, and SD card can be added to store the historical data of the cell.

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