EV Charging Cost Formula Explained
Understanding the calculation behind the tool helps you better estimate EV charging costs manually if needed.
1. Energy Required Formula
EnergyRequired=BatteryCapacity×(ChargeDifference/100)
Explanation:
- Battery capacity = total energy storage (kWh)
- Charge difference = target charge − current charge
2. Charging Cost Formula
ChargingCost=EnergyRequired×ElectricityRate
Explanation:
This calculates how much money you will spend based on electricity price per kWh.
3. Charging Time Formula
ChargingTime=EnergyRequired÷ChargerPower
Explanation:
This estimates how long it will take to charge your EV based on charger speed.
Example Calculation (Real-World Scenario)
Let’s understand how the EV Charging Cost Calculator works with a real example.
Scenario:
- Battery Capacity: 60 kWh
- Current Charge: 30%
- Target Charge: 80%
- Electricity Rate: $0.15 per kWh
- Charger Power: 7 kW
Step 1: Charge Difference
80% − 30% = 50%
Step 2: Energy Required
60 × (50 / 100) = 30 kWh
Step 3: Charging Cost
30 × 0.15 = $4.50
Step 4: Charging Time
30 ÷ 7 = 4.28 hours
Final Result:
- Energy Required: 30 kWh
- Charging Cost: $4.50
- Charging Time: 4.28 hours
This shows how affordable and predictable EV charging can be when properly calculated.
