The duration a 48V 200Ah battery will last depends on the load it supports. For example, if a device draws 1000 watts, the battery can last approximately 4 hours (calculated as 48V x 200Ah = 9600Wh; 9600Wh / 1000W = 9.6 hours). However, actual runtime may vary based on efficiency and battery condition.
Understanding Battery Runtime Calculations
When determining how long a battery will last, several factors must be considered, including the load, battery capacity, and efficiency. Below, we break down these elements to provide a clearer understanding of battery runtime.
1. Battery Capacity Explained
Battery capacity is measured in amp-hours (Ah) and indicates how much current a battery can supply over time. A 200Ah battery at 48 volts has a total energy capacity of:
| Voltage | Capacity (Ah) | Total Energy (Wh) |
|---|---|---|
| 48V | 200Ah | 9600Wh |
This means that under ideal conditions, the battery can supply up to 9600 watt-hours of energy.
2. Load Calculation
To estimate how long the battery will last under different loads, we can use the formula:
- Runtime (hours) = Total Energy (Wh) / Load (W)
For example, if an appliance uses 500 watts:
- Runtime = 9600Wh / 500W = 19.2 hours
Conversely, for a 1500-watt load:
- Runtime = 9600Wh / 1500W = 6.4 hours
3. Efficiency Considerations
It is essential to factor in efficiency losses due to inverter use and other system components. Typically, inverters operate at about 85-90% efficiency, which affects the actual usable energy:
- Effective Energy = Total Energy x Efficiency
For a system with an inverter efficiency of 90%:
- Effective Energy = 9600Wh x 0.90 = 8640Wh
Using this effective energy for calculations provides a more accurate estimate of runtime.
4. Real-World Factors Affecting Runtime
Several real-world factors can influence how long a battery lasts:
- Depth of Discharge (DoD): Regularly discharging a lithium battery to its full capacity can reduce its lifespan. For LiFePO4 batteries, it is recommended to use only up to 80% DoD.
- Temperature: Extreme temperatures can affect battery performance and capacity.
- Age and Condition: Older batteries may not hold their rated capacity as effectively as new ones.
