- Sustainable Power: 2507kW (both charge and discharge)
- DC-Side Efficiency: ≥93% under nominal conditions
The system utilizes 314Ah lithium iron phosphate (LFP) cells, each with a nominal voltage of 3.2V and a working range of 2.8–3.6V. These cells demonstrate exceptional thermal stability, operating reliably at -20°C to +60°C (discharge) and 0°C to +60°C (charge) .
Advanced Thermal Management System
Equipped with a 60kW liquid cooling unit, the compartment maintains cell temperatures within ±2°C via:
- Refrigerant: R410A
- Coolant: 50% ethylene glycol aqueous solution
- Circulation Flow: 500L/min
- Noise Level: <85dB
- Dimensions: 1200×440×2400mm
This system ensures consistent performance in extreme climates, from -30°C mountain regions to +50°C desert zones .
Intelligent Battery Management System (BMS)
Yijia Solar’s three-tier BMS delivers:
- SOC Estimation Accuracy: <8%
- Temperature Measurement Precision: ±2°C
- Cell Voltage Monitoring: ±0.3% accuracy
