A 5.12 kWh LiFePO4 (Lithium Iron Phosphate) battery is often used in energy storage systems, including solar power setups, backup power systems, and off-grid solutions. Here’s an overview of the specifications and features typically associated with such a battery:
Key Specifications:
- Battery Type: Lithium Iron Phosphate (LiFePO4)
- Capacity: 5.12 kWh (kilowatt-hours)
- Voltage: Usually 48V (but can vary; some might be 24V systems)
- Charge/Discharge Cycles: Often rated for 3000-6000 cycles at 80% Depth of Discharge (DoD)
- Rated Capacity: Around 100-200 Ah (Amp-hours), depending on the specific model
- Efficiency: High round-trip efficiency, usually between 95-98%
- Operating Temperature Range: Commonly -20°C to 60°C for discharge, 0°C to 45°C for charging
- Weight: Approximately 40-60 kg (depending on the specific configuration and casing)
- Dimensions: Varies, but typically compact for easier installation (e.g., wall-mountable or rack-compatible)
Features:
- Safety: LiFePO4 chemistry is known for being stable and safe, with lower risks of overheating or thermal runaway compared to other lithium-ion chemistries.
- Longevity: These batteries have a long cycle life, making them ideal for renewable energy applications where frequent cycling is required.
- BMS (Battery Management System): Includes protection for over-voltage, over-current, short-circuit, and temperature monitoring to extend battery life and enhance safety.
- Scalability: Can be connected in series or parallel to increase voltage or capacity, allowing for expansion as energy needs grow.
