The 2MWh semi-solid battery energy storage system employs advanced SSB 3.2V/280Ah cells combined with an efficient air cooling system. This large-scale system offers enhanced safety, high energy density, and stable performance with simplified thermal management. It is designed for commercial and industrial applications requiring robust, scalable, and reliable energy storage solutions.

The 2MWh system is suitable for:

• Grid peak shaving and load leveling to reduce electricity costs and demand charges.
• Integration with large photovoltaic systems for energy time-shifting and maximizing self-consumption.
• Backup power for critical infrastructure and industrial facilities.
• Support for microgrids and energy resilience in commercial campuses or industrial parks.

Each SSB 3.2V/280Ah cell stores about 0.896kWh. To reach 2MWh, approximately 2,230 cells are configured in optimized series-parallel arrangements. The system integrates advanced Battery Management System (BMS), Energy Management System (EMS), and Power Conversion System (PCS) to ensure safe, efficient operation with real-time monitoring. The air cooling system maintains optimal temperature to extend battery life and maintain system stability.

Air cooling offers several benefits for large-scale semi-solid BESS:

• Reduced initial and maintenance costs compared to liquid cooling systems.
• Simplified system design and fewer components, reducing potential failure points.
• Quiet operation, suitable for commercial and industrial environments.
• Effective temperature management when installed in well-ventilated or climate-controlled indoor spaces.

The semi-solid BESS offers excellent cycle durability, typically exceeding 6,000 full charge-discharge cycles under standard operating conditions. This corresponds to a service life of 10 to 15 years depending on usage and maintenance. The stable chemistry of semi-solid cells minimizes degradation, enhancing safety and reliability for long-term commercial and industrial energy storage applications.
