GCE 720V 125A 4U iron case master slave BMS high voltage relay
contactor BMS for battery pack solution solar battery ESS
About GCE high voltage BMS(HV BMS):
GCE high voltage BMS(HV BMS) is an overall BMS solution, which
included slave BMS(BMU), master BMS(RBMS), Stack BMS (SBMS), with a
3-level
structure BMS solution.BMU is collecting voltage, tempreture
information from each cell and balancing the voltage difference.
GCE BMU has 8 strings, 12S-16S, 17S-24S three types to make battery
modules with different basic pack units.RBMS is highly integrated
main control of BMS, all cells in series information shall be
processed by RBMS and it will Issue operation instructions
according to the health of each cell information collected.SBMS has
rich interfaces for many RBMS in parallel connection. SBMS has a 7
inch touch screen to display all the health information of each
cells in series and parallel. It also can set parameters for each
battery pack, each battery rack and battery stack.Moreover,SBMS
supports EBMS connecting, cloud storage setting...
GCE high voltage BMS(HV BMS) features:
| 1 | Advanced battery management system---The highly integrated battery
management system can realize seamless monitoring. |
| 2 | 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. |
| 4 | Modular design, configurable and expandable---multiple energy
storage units can be flexibly combined and expanded into a larger energy storage system. |
| 5 | Abundant communication interfaces---multiple RS485, CAN, Ethernet,
dry contact input and output interfaces, supporting communication
with most PCS and monitoring servers on the market. |
| 6 | 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 |
| 8 | Automatic circulation control and automatic parallel/offline
control can easily realize the parallel connection of battery
packs. |
