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 (For Wh and kWh)
E = V × C × 3600 (For Joules and Kilojoules)
Where:
- E: Stored energy (in Wh, kWh, Joules, or Kilojoules)
- V: Voltage (in volts)
- C: Battery capacity (in ampere-hours)
- 3600: Conversion factor from hours to seconds (for Joules)
Example Calculations
Example 1: Wh Calculation
- Voltage: 12V
- Battery Capacity: 100Ah
- Stored Energy:
12 × 100 = 1,200 Wh
- Result: 1,200 Wh
Example 2: kWh Calculation
- Voltage: 48V
- Battery Capacity: 200Ah
- Stored Energy:
48 × 200 = 9,600 Wh = 9.6 kWh
- Result: 9.6 kWh
Example 3: Joules Calculation
- Voltage: 12V
- Battery Capacity: 50Ah
- Stored Energy:
12 × 50 × 3600 = 2,160,000 J
- Result: 2,160,000 Joules (J)
Example 4: Kilojoules Calculation
- Voltage: 24V
- Battery Capacity: 10Ah
- Stored Energy:
24 × 10 × 3600 = 864,000 J
- Result: 864 kJ (Kilojoules)
