Understanding Battery Capacity
The capacity of a battery is a measure of the energy it can store. The relationship between voltage, battery capacity, and stored energy is given by the formula:
Formula:
E = V × C × 3600
Where:
- E: Stored energy (in joules)
- V: Voltage (in volts)
- C: Battery capacity (in ampere-hours)
- 3600: Conversion factor from hours to seconds
Example Calculations:
- Example 1:
- Voltage: 12V
- Battery Capacity: 100Ah
- Stored Energy:
12 × 100 × 3600 = 4,320,000 J
- Result: 4,320,000 Joules (J)
- Example 2:
- Voltage: 500mV (converted to volts = 0.5V)
- Battery Capacity: 2000mAh (converted to Ah = 2Ah)
- Stored Energy:
0.5 × 2 × 3600 = 3,600 J
- Result: 3,600 Joules (J)
