Battery Chemistry: LiFePO4, or Lithium Iron Phosphate, is a type of lithium-ion battery known for its high energy density, long cycle life, and thermal stability.
It's a safer alternative to other lithium-ion chemistries like LiCoO2 (Lithium Cobalt Oxide) due to its lower risk of thermal runaway and reduced sensitivity to high temperatures.
Capacity: The ESS features a 2.56 kWh capacity, which refers to the total amount of energy it can store. This capacity is suitable for a variety of applications, including residential energy backup, off-grid power systems, and commercial energy management.
Voltage: LiFePO4 batteries typically have a nominal voltage of 3.2-3.3 volts per cell. The specific voltage range of the battery cells in this ESS will depend on the configuration and arrangement of cells within the pack.
Cycle Life: LiFePO4 batteries are known for their impressive cycle life, often exceeding 2,000 cycles. This means the battery can be charged and discharged over 2,000 times before experiencing significant capacity degradation. The actual cycle life may vary depending on factors like depth of discharge and operating conditions.
Efficiency: LiFePO4 batteries are highly efficient, with charge and discharge efficiencies typically exceeding 90%.
This means that the ESS can effectively store and release energy with minimal losses.
Operating Temperature: LiFePO4 batteries have a wide operating temperature range, typically between -20°C to 60°C (-4°F to 140°F). This makes them suitable for use in various climates and environments.
Safety: LiFePO4 batteries are considered one of the safest lithium-ion battery chemistries. They have a higher thermal runaway temperature, which reduces the risk of fire or explosion in case of overheating. Additionally, they are less prone to thermal runaway due to puncture or physical damage.
Charging and Discharging Rates: LiFePO4 batteries can be charged and discharged at relatively high rates, which makes them suitable for applications with varying power demands.
Battery Management System (BMS): An ESS typically includes a Battery Management System to monitor the state of charge, voltage, and temperature of individual cells within the battery pack. The BMS helps ensure safe and optimal operation.
