LiFePO4 Battery Charging & Discharging Explained
The charging and discharging process of LiFePO4 batteries involves managing the SoC to ensure optimal performance and longevity. During charging, the battery voltage gradually increases until it reaches the full charge voltage. Similarly, during discharging, the voltage decreases as the battery's capacity is used up.
Monitoring the SoC is crucial for maintaining battery health. Overcharging or deep discharging can lead to reduced battery capacity and a shorter lifespan. Using a Battery Management System (BMS) can help prevent these issues by providing real-time monitoring and protection.
Effects of Voltage on LiFePO4 Battery Performance
The voltage of a LiFePO4 battery significantly affects its capacity, efficiency, and cycle life. Operating the battery at optimal voltage levels ensures maximum performance and longevity. Maintaining the correct voltage also helps prevent issues such as overheating and over-discharging.
