Charging Efficiency

Required Energy: -- kWh

Charging Time: --

Formulas

Step 1: Required Energy

Required Energy = Battery Capacity × (Target% – Current%) ÷ 100

Step 2: Charging Time

Charging Time = Required Energy ÷ (Charger Power × Efficiency)

Where:
- Battery Capacity = total EV battery size in kWh
- Current% = current state of charge
- Target% = desired charge level
- Charger Power = charging station output in kW
- Efficiency = charging losses (0–100%)
