100A for 2 hours
50A for 4 hours
Nominal Voltage Considerations
LiFePO4 batteries typically have a nominal voltage of 3.2V per cell. For a standard 12V configuration, four cells are connected in series, resulting in a nominal voltage of approximately 12.8V. Understanding this voltage is crucial for calculating energy capacity in kilowatt-hours (kWh).
Energy Capacity Calculation
To calculate the total energy capacity in kilowatt-hours (kWh), we use the formula:
kWh=(Ah×Voltage1000)Â
For a 200Ah LiFePO4 battery at 12V:
kWh=(200 Ah×12 V1000)=2.4 kWhÂ
This means that a fully charged 200Ah LiFePO4 battery can store up to 2.4 kWh of energy.
Calculating Runtime Based on Load
The runtime of a 200Ah LiFePO4 battery depends on the load applied. To estimate how long the battery will last under different loads, we can use the following formula:
While calculating runtime is essential, several factors influence how long a LiFePO4 battery will last over its entire lifespan:
1. Depth of Discharge (DoD)
The depth of discharge refers to how much capacity is used relative to the total capacity of the battery. For LiFePO4 batteries, it is advisable to limit DoD to around 80% to maximize lifespan.
A battery with a DoD of 80% means you only use up to 160Ah before recharging.
2. Charging Cycles
LiFePO4 batteries typically offer over 2000 cycles at an 80% DoD, making them suitable for long-term use in various applications.
3. Temperature Conditions
Operating at extreme temperatures can affect performance and lifespan:
Optimal Temperature: LiFePO4 batteries perform best between 20°C and 25°C.
High temperatures can lead to faster degradation, while very low temperatures may reduce capacity temporarily.
