Battery Energy Fundamentals
Amp Hours (Ah)
Amp hours measure battery capacity:
- Current × Time = Ah capacity
- Higher Ah = longer runtime
- Discharge rate affects capacity
Energy Storage
- kWh = total energy stored
- Voltage affects system efficiency
- Energy = Power × Time
Key Formula:
kWh = (Ah × V) / 1000
Energy (kWh) = Capacity (Ah) × Voltage (V) ÷ 1000
Calculation Formula
Battery Energy Conversion:
kWh = (Ah × V) / 1000
Where:
Ah = Amp Hours (battery capacity)
V = Voltage (battery voltage)
Example Calculation
12V Battery with 100Ah capacity:
Amp Hours: 100Ah
Voltage: 12V
Wh = 100Ah × 12V = 1200Wh
kWh = 1200Wh / 1000 = 1.2kWh
This battery can deliver 1.2 kilowatt hours of energy
