The 215kWh semi-solid battery energy storage system uses advanced semi-solid-state battery cells (SSB 3.2V/280Ah) combined with an air cooling thermal management system. This design offers high safety performance due to the stable chemistry of semi-solid cells, excellent cycle life, and efficient heat dissipation through air cooling. It is ideal for commercial and industrial applications requiring medium-scale energy storage with reliable performance and manageable maintenance.

This 215kWh system is well suited for:

• Commercial peak shaving and demand charge management to reduce electricity costs.
• Integration with photovoltaic solar systems for energy time-shifting and maximized self-consumption.
• Providing uninterruptible power supply (UPS) and backup power for critical operations.
• Microgrid support in small industrial parks or commercial campuses.

These applications benefit from the system’s long cycle life, stable performance, and effective thermal management.

Each semi-solid cell delivers approximately 0.896kWh (3.2V × 280Ah). To reach a total of 215kWh, the system consists of around 240 cells connected in optimized series and parallel arrangements. The overall system integrates advanced Battery Management System (BMS), Energy Management System (EMS), and Power Conversion System (PCS) components to ensure safe, efficient operation and real-time monitoring. The air cooling system maintains optimal temperature to extend battery life and maintain performance stability.

Air cooling in the 215kWh system provides several benefits:

• Lower upfront and maintenance costs compared to liquid cooling systems.
• Simplified installation and fewer potential points of failure.
• Quiet operation, suitable for commercial environments.
• Effective thermal regulation when installed in well-ventilated or climate-controlled indoor areas.

While air cooling is efficient for moderate environments, it requires proper ventilation design to ensure heat is adequately dissipated.

Thanks to the semi-solid cell chemistry, this system offers excellent cycle life, typically exceeding 6,000 charge-discharge cycles under standard operating conditions. This translates into a service life of 10 to 15 years, depending on usage patterns and maintenance. The stable chemistry reduces degradation and enhances safety, making the system reliable for long-term commercial and industrial energy storage applications.
