A 48V 100Ah battery can last approximately 5 to 10 hours depending on the load it supports. For example, if the battery powers a device drawing 500 watts, it will last around 10 hours (100Ah x 48V = 4800Wh; 4800Wh / 500W = 9.6 hours). Factors like efficiency and discharge rates can affect this duration.
Understanding Battery Capacity and Runtime
To accurately determine how long a 48V 100Ah battery will last, it’s essential to understand several key factors:
- Battery Capacity: The capacity of a battery is measured in amp-hours (Ah). A 100Ah rating means the battery can theoretically deliver 100 amps for one hour, or 1 amp for 100 hours.
- Voltage: The voltage rating (in this case, 48V) indicates the electrical potential of the battery. The total energy capacity can be calculated using the formula:
Total Energy Wh =Voltage V ×Capacity Ah
For a 48V 100Ah battery, this equals:
48V×100Ah=4800Wh - Load Requirements: The duration the battery lasts depends significantly on the load it is powering. Higher loads will drain the battery faster, while lower loads will extend its runtime.
- Efficiency Losses: Real-world conditions often lead to efficiency losses due to factors such as heat generation and internal resistance. It is common to account for about 80-90% efficiency, meaning that not all stored energy is usable.
- Depth of Discharge (DoD): The lifespan of a battery is also affected by how deeply it is discharged. For lithium batteries, it’s advisable to maintain a DoD of around 80% for optimal longevity.
| Factor | Description |
|---|---|
| Capacity | 100Ah indicates total charge available |
| Voltage | 48V provides energy potential |
| Load Requirements | Higher loads reduce runtime |
| Efficiency Losses | Real-world usage typically sees 80-90% efficiency |
| Depth of Discharge | Aim for an 80% DoD for lithium batteries |
Calculating Runtime Examples
To illustrate how long a 48V 100Ah battery will last under different loads, consider the following examples:
- 500W Load:
- Total Energy: 4800Wh
- Runtime: 4800Wh500W=9.6 hours
- 1000W Load:
- Total Energy: 4800Wh
- Runtime: 4800Wh1000W=4.8 hours
- 200W Load:
- Total Energy: 4800Wh
- Runtime: 4800Wh200W=24 hours
These calculations demonstrate how varying load demands directly impact the runtime of the battery.
