“Finally. A C&I Battery That Doesn’t Need Babysitting.” Highjoule’s 215kWh air-cooled SSB system is built for businesses that actually need reliability – not more headaches. ✓ Semi-solid state (SSB) 3.2V/280Ah cells – Zero thermal runaway risk (unlike those fire-prone lithium packs) ✓ Passive air cooling – No pumps, no coolant leaks, no energy wasted (just set it and forget it) ✓ 215kWh modular blocks – Scale from warehouse backup to factory power overnight ✓ 30% lower TCO – Fewer parts, no liquid maintenance, just raw uptime
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:
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:
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.
