High voltage BMS wholesale/FOB

RBMS products are battery management systems developed for large-scale high-voltage battery energy storage systems and UPS applications. Using distributed architecture, modular design concept, with high configurability, easy to assemble, debug, maintenance, suitable for a variety of battery energy storage systems with DC voltage below 1000V. This product can be configured as a secondary architecture (BMU+RBMS) at least, suitable for 10KWh-100KWh occasions. In conjunction with industrial computers and battery stack management software, a three-stage architecture (BMU+RBMS+SBMS) can be formed, which is suitable for 50KWh-2MWh occasions. In conjunction with the server and power station battery management system software, a four-stage architecture (BMU+RBMS+SBMS+BBMS) can be formed, which is suitable for applications from 2MWh to 1000MWh to meet different project needs.
The product has a complete and reliable operation and protection strategy, which effectively extends the service life of the battery pack. Comes with a variety of communication interfaces that can be directly or indirectly connected to third-party energy management systems.

Product features
※ Advanced battery management system --- highly integrated battery management system can achieve seamless monitoring.
※ Perfect self-test and operating status detection function, with HMI display, the system operation information is clear at a glance.
※ Improve and reliable system control and protection strategies, fully guarantee battery safety, and escort the life of the battery pack.
※ Modular design, configurable, scalable--- multiple energy storage units can be flexibly combined to expand into a larger energy storage system, up to 256 cells (lead-carbon batteries for 400 cells) battery series.
※ Rich communication interface--- multiple RS485, CAN, Ethernet, dry contact input and output interfaces, support communication with most PCS and monitoring servers on the market.
※ The communication interface protocol is flexible--- the factory comes with the company's communication protocol, and it can also adapt to the PCS of different manufacturers according to customer needs.
※ There is a large --- built-in mass memory chip can store a large number of key operating data, and SD card can be installed to achieve battery cell history data storage
※ Automatic circulation control and automatic paralleling \ offline control, which can easily realize the parallel connection of battery packs.
