• APPLICATION SCENARIO
  1. Home storage

  2. Island off-grid energy storage

  3. Micro-grid applications

  4. UPS power supply

  5. Power System 220V DC power supply

1.It is high integrated with less installation space.

2.Long life cycle, >3000 times at 80% DOD.

3.It without heavy metals and environment friendly.

4.Maintenance free,there is no memory effect.

5.Internal BMS with full protection,battery has high voltage protection with higher reliability.

6. Master and Slave all in one.

GCE has R&D high voltage bms for nearly 10years, we have 3-level structure of BMS with perfect solution for basic battery modules in series and parallel to make 100kwh to 1Gwh or more. please refer to the picture, we install BMU(slave bms) into the basic battery modules, each module is connected in cascade by Isolated CAN bus wire harness till to RBMS(rack bms /master bms).BMU collecting voltage, and temperature from each cell of modules. The voltage balance between battery modules can be achieved by starting the fan or balancing the resistance. We can set the ID number of each RBMs through the dial switch, and make each RBMS in parallel by network cable. We use Stack BMS collecting all information from each RBMS. GCE has rich interface reservation and is very friendly to the access of external systems.The core technology of GCE is to ensure stable, efficient and reliable system communication.
