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
