Product Description

GCE 480V 400A 5U 19 inch iron case high voltage BMS parallel function master BMS with insulation for lithium modules


480V BMS can be applied to 10pcs 15S(48V) lithium, 13-14S NMC,24S LTO battery packs in series.


GCE high voltage BMS introduction:

GCE high voltage BMS is an intelligent overall solution. We can connect battery modules with different types of strings in series to higher voltage systems, GCE BMS will assign addresses to each connected battery module, and if a cell is damaged, we can easily Find and replace it. Multiple battery clusters can also be assigned addresses through DIP switches. We allow 8 battery clusters to be connected in parallel. Of course, you can also connect more battery clusters in parallel to meet your MWh energy storage needs. But our suggestion is that you can use every 8 battery clusters as a battery bank and have N battery banks in parallel. Our BMU can be divided into 8 series, 12-16 series, 17-24 series of three specifications of PCB. In this way, you can meet the average distribution of your various total strings of batteries.


GCE high voltage BMS Application:


2.solar plant, energy storage

3.UPS (Uninterruptible power supply)

4.forklift VGA 

5.low speed vehicles

6. energy storage charging piles

7. family energy storage

GCE high voltage BMS features:


1 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.

3 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.

7 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.
