| Fully Charged | 58.4 |
| Nominal | 51.2 |
| Low Voltage Cut-off | 40 |
How Does State of Charge (SOC) Relate to Voltage in a 48V Battery?
The State of Charge (SOC) refers to the remaining usable capacity of a battery, expressed as a percentage. In a 48V battery system, SOC can be estimated by measuring the open circuit voltage (OCV). As the battery discharges, the OCV decreases, indicating lower SOC.
| SOC (%) | Voltage (V) |
|---|---|
| 100 | 58.4 |
| 90 | 53.6 |
| 80 | 52.8 |
| 50 | 48.4 |
| 20 | 46.0 |
| 0 | 40 |
What Factors Affect the Voltage Levels in a 48V Battery?
Several factors influence voltage levels in a 48V battery, including:
- Battery Chemistry: Different chemistries (LiFePO4, NCM, lead-acid) have varying voltage characteristics.
- Temperature: Extreme temperatures can affect battery performance and voltage readings.
- Load Conditions: The presence of connected loads can impact the voltage output during discharge.
Understanding these factors is essential for accurate monitoring and maintenance.
