Ii. Product system overview
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 500V. This product can be configured as a secondary architecture (BMU+RBMS) at least, suitable for 10KWh-100KWh occasions. In conjunction with industrial computer and battery stack management software, a three-stage architecture (BMU+RBMS+SBMS) can be formed, which is suitable for 50KWh-2MWh occasions 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.
