Opening the cabinet reveals a highly compact and robust structural layout designed for simplified maintenance and efficient space utilization.
At the bottom left are two high-voltage battery cluster control boxes, integrating:
BMU (Battery Management Unit)
Circuit breakers
Cluster management components
Each cluster manages 4 battery packs.
Battery Pack Configuration
Each battery pack: 52.25kWh
Nominal voltage per pack: 166.4V
Nominal capacity: 314Ah
Each pack is equipped with an independent BCU
Total packs: 8 battery packs
Total system capacity: 418kWh
This modular cluster design enhances redundancy, safety, and precise battery management.
Liquid Cooling for Extreme Environments
Positioned above the battery cluster control boxes is the liquid-cooling unit, responsible for thermal regulation of all battery modules.
Benefits include:
Uniform temperature control
Extended battery lifespan
Higher operational efficiency
Exceptional performance in sub-zero and high-temperature climates
Multi-Layer Fire & Explosion Protection
At the top of the cabinet:
Heat detector
Smoke detector
Aerosol fire suppression module
In extreme thermal runaway scenarios, the system automatically activates fire suppression.
Additionally, every battery pack includes a pressure relief valve, creating an explosion-proof safety design by automatically releasing internal pressure when necessary.
Intelligent Control & Power Conversion
On the cabinet door:
HMI touch screen with self-developed EMS
I/O module for system communication
Dehumidifier to control internal humidity
Externally mounted on both sides:
Two 80kW PCS units (total 160kW)
Responsible for converting and managing power flow between:
DC battery
AC grid
AC loads
This configuration ensures highly efficient bidirectional energy conversion for on-grid and off-grid C&I applications.
