GCE High Voltage Battery Management System 225S 720V 400A Relay Solution Master Slave BMS
Model Number:RBMS07S20-250A336V

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, extend the life of the battery escort.
4. Modular design, configurable, scalable --- flexible combination of multiple energy
storage unit can be expanded to a larger energy storage system, the maximum can support 272 (lead-carbon battery 400) battery
series.
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 .
9. PCS without protocol control function, the choice of contactor + breaker version.
10. Automatic circulation control and automatic parallel machine off-line control, can be easily parallel battery. (Model suffix selection D).
