Product Description:
Our RBMS (Battery Management System) is designed specifically for high-voltage battery energy storage systems and UPS applications on a large scale. Featuring a distributed architecture and modular design, our RBMS ensures effortless assembly, configuration, and maintenance. It is ideal for battery energy storage systems with DC voltages below 1000V, offering exceptional flexibility, scalability, and adaptability.
Our RBMS can be easily configured as a second-level architecture (BMU+RBMS) for projects ranging from 10KWh to 100KWh. By integrating it with an industrial computer and battery stack management software, multiple battery clusters can form a three-level architecture (BMU+RBMS+SBMS) suitable for projects between 50KWh and 2MWh. Furthermore, seamless integration with servers and power station battery management system software enables the formation of a four-level architecture (BMU+RBMS+SBMS+BBMS), catering to projects from 2MWh to 1000MWh.
Equipped with a comprehensive and reliable operation and protection strategy, our RBMS significantly extends the lifespan of your battery pack. It offers various communication interfaces to seamlessly integrate with third-party energy management systems, ensuring efficient connectivity.
Experience unparalleled performance, scalability, and adaptability with our RBMS. Empower your business to optimize energy storage, enhance efficiency, and meet the demands of your projects. Simplify battery management with utmost confidence and reliability by utilizing our RBMS in your energy storage systems and UPS applications.
