This 1MWh battery energy storage system adopts semi-solid-state lithium battery cells (SSB 3.2V/280Ah) and air cooling. It combines enhanced safety, high energy density, and long life with simplified thermal management, making it suitable for commercial and light industrial energy applications.

The system is ideal for:

• Peak load management and time-of-use energy optimization
• Commercial PV-storage integration
• EV charging stations
• Microgrid and emergency backup support

Each SSB 3.2V/280Ah cell stores about 0.896kWh. To achieve 1MWh, the system typically consists of over 1,100 cells arranged in optimized series-parallel packs. The system includes a BMS, EMS, PCS, and air-cooled enclosures to manage safety, efficiency, and thermal stability.

Air cooling offers the following benefits:

• Lower maintenance and operational costs
• No coolant circulation systems needed
• Reduced system complexity
• Suitable for moderate climates or controlled indoor installations

The semi-solid BESS system can exceed 6,000 cycles and deliver 10–15 years of reliable service. Its improved thermal and chemical stability reduces degradation and extends usable life, even with daily cycling.
