Electric Vehicle Charging Calculator

Electric Vehicle Charging Calculator is a practical tool designed to estimate the cost, time, and energy consumption of charging electric vehicles efficiently.

What does the Electric Vehicle Charging Calculator do?

Electric Vehicle Charging Calculator helps users determine how much energy is required, the time it will take, and the estimated cost for charging their electric vehicle.

Electric Vehicle Charging Calculator formula?

The calculator typically applies these formulas depending on the type of calculation:

Energy Required (kWh) = Battery Capacity (kWh) × (Target Charge % – Current Charge %) / 100
Charging Time (hours) = Energy Required (kWh) / Charging Speed (kW)
Charging Cost = Energy Required (kWh) × Electricity Rate (per kWh)

Where:

• Battery Capacity is the total storage capacity of the electric vehicle’s battery.
• Target Charge % is the desired charge level of the battery.
• Current Charge % is the current charge level.
• Charging Speed refers to the charging power provided by the charger.
• Electricity Rate is the cost of electricity per kWh.

Electric Vehicle Charging Calculator example?

Example 1:

Calculate the charging cost, energy required, and charging time for an electric vehicle with a 60 kWh battery, starting at 20% charge and aiming for 80% charge. The charger speed is 7 kW, and the electricity rate is $0.15 per kWh.

1. Energy Required (kWh):
   • Formula: Battery Capacity × (Target Charge % – Current Charge %) / 100
   • Energy Required = 60 × (80 – 20) / 100
   • Energy Required = 60 × 0.6 = 36 kWh
2. Charging Time (hours):
   • Formula: Energy Required / Charging Speed
   • Charging Time = 36 / 7
   • Charging Time ≈ 5.14 hours
3. Charging Cost ($):
   • Formula: Energy Required × Electricity Rate
   • Charging Cost = 36 × 0.15
   • Charging Cost = $5.40

Results:

• Energy Required: 36 kWh
• Charging Time: Approximately 5.14 hours
• Charging Cost: $5.40

Example 2:

An electric vehicle with a 75 kWh battery is at 10% charge and needs to reach 90% charge. The charger speed is 11 kW, and the electricity rate is $0.20 per kWh.

1. Energy Required (kWh):
   • Formula: Battery Capacity × (Target Charge % – Current Charge %) / 100
   • Energy Required = 75 × (90 – 10) / 100
   • Energy Required = 75 × 0.8 = 60 kWh
2. Charging Time (hours):
   • Formula: Energy Required / Charging Speed
   • Charging Time = 60 / 11
   • Charging Time ≈ 5.45 hours
3. Charging Cost ($):
   • Formula: Energy Required × Electricity Rate
   • Charging Cost = 60 × 0.20
   • Charging Cost = $12.00

Results:

• Energy Required: 60 kWh
• Charging Time: Approximately 5.45 hours
• Charging Cost: $12.00

Electric Vehicle Charging Calculator offers users an efficient way to manage their vehicle’s energy needs by providing clear insights into cost, time, and energy consumption.
