The full charge voltage of a 24V LiFePO4 battery typically reaches around 29.2 volts. This voltage is crucial for ensuring that the battery is fully charged without exceeding safe limits, which can lead to damage or reduced lifespan.
What Is the Full Charge Voltage for a 24V LiFePO4 Battery?
A 24V LiFePO4 battery, which consists of eight cells connected in series, achieves a full charge voltage of approximately 29.2 volts. Each cell in a LiFePO4 battery has a maximum voltage of about 3.65 volts when fully charged. Therefore, for eight cells, the calculation is:
| Configuration | Fully Charged Voltage | Discharged Voltage |
|---|---|---|
| 24V | 29.2V | 20.0V |
This table illustrates the voltage levels for fully charged and discharged states in a 24V configuration.
How Does State of Charge Affect Voltage Levels in LiFePO4 Batteries?
The state of charge (SoC) directly influences the voltage levels in LiFePO4 batteries. As the battery discharges, its voltage decreases gradually. Here’s how different SoC percentages correspond to voltage levels:
| State of Charge (%) | Voltage (V) |
|---|---|
| 100% | 29.2 |
| 90% | 26.8 |
| 80% | 26.6 |
| 70% | 26.4 |
| 60% | 26.2 |
| 50% | 26.0 |
| 40% | 25.8 |
| 30% | 25.6 |
| 20% | 25.0 |
| 10% | 24.0 |
| 0% | 20.0 |
This chart shows how voltage varies with SoC, helping users monitor battery health and performance.
What Are the Recommended Charging Parameters for 24V LiFePO4 Batteries?
For optimal performance and safety, it is essential to adhere to specific charging parameters when charging a 24V LiFePO4 battery:
- Charging Voltage: The recommended charging voltage is between 28.4V and 29.2V.
- Float Voltage: After reaching full charge, maintain a float voltage around 27.2V.
- Maximum Voltage: Do not exceed 29.2V during charging to prevent overcharging.
Following these guidelines ensures efficient charging while preserving battery health.
