High-voltage BMS adopts the master-slave structure of the relay program, will be more than the same number of strings and capacity of lithium battery pack connected in series to form a battery rack, and then multiple clusters of batteries through the software and hardware technology means parallel connection to form a battery stack, multiple battery stacks can continue to be connected to the battery bank, so the stepwise stacking can make the group control high-voltage BMS software and hardware equipment to monitor the working status of each lithium battery, there by effectively controlling the charging and discharging rhythm, so that the stepwise stacking can make the group control high-voltage BMS software and hardware equipment to monitor the working status of each lithium battery, so as to effectively control the charging and discharging rhythm of lithium batteries, equalization and repair of part of the state of the abnormal or damaged batteries, to provide users with the correct operation recommendations.
RBMS products are battery management systems developed for large-scale high-voltage battery energy storage systems and UPS applications. Adopting distributed architecture and modular design concept, it is highly configurable, easy to assemble, debug and maintain, and is suitable for various battery energy storage systems with DC voltage below 1000V. This product can be configured as a minimum two-level architecture (BMU+RBMS), 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-2MWhoccasions. 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.
Product Features of High Voltage BMS
1.Advanced Battery Management System --- The highly integrated battery management system enables seamless monitoring.
2. Perfect self-test and operation status detection function, with HMI display, the system operation information is clear at a glance.
3.Perfect and reliable system control and protection strategy, comprehensively safeguard battery safety and escort for extending the life of the battery pack.
4.Modular design, configurable and expandable---Multiple energy storage units can be flexibly combined and expanded into a larger energy storage system, which can support a maximum of 270 (lead-carbon battery is 400) batteries in series.
5.Abundant communication interfaces---Multiple RS485, CAN, Ethernet, dry contact input and output interfaces support communication with most PCS and monitoring servers on the market.
6.Flexible communication interface protocols----the factory comes with the company's communication protocols, can also be adapted to different manufacturers of PCS according to customer demand.
7.There is a lot of capacity----built-in high-capacity memory chip can store a large number of key operating data, and can be added to the SD card to realize the storage of historical data of the battery cell.
8. Automatic loop current control and automatic parallel offline control, can easily realize the parallel connection of the battery pack.
