Description

GCE +/-240V 250A 4U master BMS with center tap


BMS with center tap is main apply to UPS(Uninterruptible power supply)

If you want to make +/- battery packs in series, the quantity of battery modules must be even numbers

for +/- 240V battery systems has 10 battery packs in series, but you need to make a power cable from battery  module No.5 and battery module NO.6 and connect to the “N” pole of master BMS (RBMS)

Product system overview

Our Rack battery management system (RBMS) is a battery management system with overall solution developed for large-scale high-voltage battery energy storage systems and lithium UPS applications. It adopts a multi-level distributed architecture and a modular design concept. It is highly configurable, compatible and expandable. It is easy to assemble, debug and maintain. It is suitable for DC voltage 96-864V (taking lithium iron phosphate as an example: minimum voltage 2.5V, rated Various lithium battery energy storage systems with a voltage of 3.2V and a maximum voltage of 3.65V, that is, up to 270 single cells can be connected in series. This system can be configured as a two-level architecture (BMU+RBMS) to form a single-cluster lithium battery system according to different customer needs, and is suitable for occasions from 10KWh to 500KWh. It can also be combined with industrial computer and battery stack management software to make multi-cluster battery systems in parallel to form a three-level architecture (BMU+RBMS+SBMS) to form a battery stack, which is suitable for 50KWh-2MWh occasions. It can also cooperate with servers and power station battery management system software to make multiple battery stacks parallel again to form a four-level architecture (BMU+RBMS+SBMS+BBMS), which is suitable for occasions from 2MWh to 1GWh.

GCE high voltage bms products have complete and reliable operation and protection strategies, which effectively extend the service life of the battery pack. Comes with a variety of communication interfaces, which can be directly or indirectly connected with third-party energy management systems.

Product Features

※ Advanced battery management system—The highly integrated battery management system can realize seamless monitoring.

※ Perfect self-checking and running status checking function, with HMI display screen,system running information is clear at a glance.

※ Complete and reliable system control and protection strategies, comprehensively guarantee battery safety, and escort to extend the life of battery packs.

※ Modular design, configurable and expandable—multiple energy storage units can be flexibly combined and expanded into a larger energy storage system.

※ Abundant communication interfaces—multiple RS485, CAN, Ethernet, dry contact input and output interfaces, supporting communication with most PCS and monitoring servers on the market.

※ The communication interface protocol is flexible—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.

※ 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

※ Automatic circulation control and automatic parallel/offline control can easily realize the parallel connection of battery packs.
