RBMS-S20-400A720V(750V) is a high voltage master BMS system with a voltage level of 750V. This type of BMS supports a rated current of 400A and a rated voltage of 720V, but it does not have a parallel function or a two-wire system.
The available RBMS voltage levels are 350, 750, and 1000, which
represent the operating voltage ranges of 120-350VDC, 260-750VDC,
and 500-1000VDC respectively.
When it comes to the actual system voltage rating calculation
method, the rated voltage for a system composed of 15 pcs 15
strings Lifepo4(lithium iron phosphate) battery modules in series
connection (15*15S) is calculated by multiplying the single nominal
3.2V by 15. Thus, the rated voltage of this system is 15* 15 * 3.2
=720V.
Advanced battery management system provides users with high integrated monitoring functions. It has perfect self-checking and running status checking functions, with HMI display screen, so that the system information is clear at a glance.Moreover, the complete and reliable control and protection strategies provide comprehensive guarantee for battery safety, and it helps to extend the life of battery packs.
Due to its modular design, configurable and expandable features,
multiple energy storage units can be flexibly combined and expanded
into a larger energy storage system, and it Supports up to 256(400
for lead-carbon batteries) batteries in series. Abundant
communication interfaces, such as multiple RS485, CAN, Ethernet,
dry contact input and output interfaces, enables communication with
most PCS and monitoring servers on the market.
Moreover,the built-in large-capacity memory chip can store a large
amount of key operating data, and an SD card can be added to
realize battery historical data storage. In addition, users can
make use of automatic circulation control and automatic
parallel/offline control to easily realize the parallel connection
of battery packs. The communication interface protocol is so
flexible that the factory comes with the company's communication
protocol, and it can also be adapted to the PCS of different
manufacturers according to customer needs.

Commercial and industrial energy storage have become common across a wide variety of applications. This includes UPS and data centers, solar battery energy storage, electric vehicle charging piles, energy storage power stations, computer rooms, rail transit, telecom base stations, utilities, and battery-supplied applications.
UPS systems and data centers have become increasingly advanced and reliable due to the use of
energy storage technology. This allows for steady power flow and
greater redundancy in power supply, as well as an increased battery
life in the event of an outage.
Solar battery energy storage is an increasingly popular approach to providing electricity with
improved reliability and environmental footprint. By storing solar
energy generated during the day, applications can make use of power
at other times, reducing dependence on grid energy. Electric
vehicle charging piles have similarly become popular as they reduce
the strain on the grid.
Energy storage power stations are another increasingly popular application, providing a robust
and reliable source of energy for larger applications. This can
include everything from university campuses to factories and
manufacturing plants.
Computer rooms, rail transit, telecom base stations, and utilities continue to implement energy storage solutions to meet specific
application requirements. Secondary batteries have also become an
increasingly popular option to provide long-term storage for home
and business applications.
