#Product Model Naming Rules

For Example: RBMS-D37-500A 750 (512V) represents the high-voltage series BMS main

control supports parallel, three-wire system, with a 7-inch display screen, the main

control voltage level is 750V, supports a maximum current of 500A, and a rated voltage

of 512V.

RBMS has three voltage levels: 350 represents the operating voltage range

120-350VDC; 750 represents the operating voltage range 260-750VDC; 1000 represents

the operating voltage range 500-1000VDC.

Regarding the calculation method of the actual rated voltage of the system: For

example, the system is composed of 10 16-series lithium iron phosphate battery modules

in series (10S16S), and the rated voltage calculated according to the nominal 3.2V

of the single unit is 10*16*3.2=512V; 8 15 The lithium iron phosphate battery modules

are connected in series (8S15S), and the rated voltage is 8*15*3.2=384V.

#Product System Overview

RBMS products are battery management systems developed for large-scale high-voltage battery

energy storage systems and UPS applications. It adopts distributed architecture and modular design

concept, which is highly configurable, easy to assemble, debug and maintain. It is suitable for

various battery energy storage systems with DC voltage below 1000V. This product can be

configured as a second-level architecture (BMU+RBMS) at least, which is suitable for

10KWh-100KWh occasions. Cooperating with industrial computer and battery stack management

software, it can form a three-level structure (BMU+RBMS+SBMS), which is suitable for

50KWh-2MWh occasions. Cooperating with the server and power station battery management

system software, it can form a four-level architecture (BMU+RBMS+SBMS+BBMS), which is

suitable for occasions from 2MWh to 1000MWh to meet different project requirements.

The product has a complete and reliable operation and protection strategy, which effectively

prolongs the service life of the battery pack. It comes with a variety of communication interfaces,

which can be directly or indirectly connected with third-party energy management systems.
