Detailed Description:

BMS Configuration:

128S409.6V 125A master BMS * 1set
16S slave BMU *8 sets
16S wire harness * 8 sets (16S 51.2V battery pack, 8 battery packs connected in series for 128S409.6V 125A system.)

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 and escort the extension of the service life of the battery pack.

• Modular design, configurable and expandable — multiple energy storage units can be flexibly combined to expand 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 communication protocol, 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
