2. Calculating Monthly Electricity Usage for Electric Cars
To estimate how much electricity your electric car uses per month, you’ll need to consider your driving habits and the efficiency of your vehicle. Here’s a step-by-step guide to help you calculate your monthly electricity consumption.
2.1. Determining Average Monthly Mileage
First, determine your average monthly mileage. You can estimate this by tracking your mileage for a few weeks or using historical data from your car’s odometer. According to the U.S. Department of Transportation, the average American driver travels about 13,500 miles per year, which translates to approximately 1,125 miles per month.
2.2. Calculating Monthly kWh Consumption
Once you have your average monthly mileage, you can calculate your monthly kWh consumption using the following formula:
Monthly kWh Consumption = (Monthly Mileage / 100) * kWh per 100 Miles
For example, if you drive 1,125 miles per month and your EV consumes 30 kWh per 100 miles:
Monthly kWh Consumption = (1,125 / 100) * 30 = 337.5 kWh
2.3. Estimating Monthly Charging Costs
To estimate your monthly charging costs, you’ll need to know the cost of electricity in your area. The U.S. Energy Information Administration provides data on average electricity rates by state. As of recent data, the national average is around 16 cents per kWh.
Monthly Charging Cost = Monthly kWh Consumption * Cost per kWh
Using the previous example, if your monthly kWh consumption is 337.5 kWh and the cost per kWh is $0.16:
Monthly Charging Cost = 337.5 kWh * $0.16 = $54.00
Therefore, your estimated monthly charging cost would be $54.00.
2.4. Factoring in Charging Efficiency and Losses
It’s important to note that the charging process isn’t 100% efficient. Some energy is lost due to heat and other factors. Charging efficiency typically ranges from 85% to 95%. To account for this, you can adjust your calculation:
Adjusted Monthly kWh Consumption = Monthly kWh Consumption / Charging Efficiency
Assuming a charging efficiency of 90%:
Adjusted Monthly kWh Consumption = 337.5 kWh / 0.90 = 375 kWh
Adjusted Monthly Charging Cost = 375 kWh * $0.16 = $60.00
So, with charging efficiency factored in, your estimated monthly charging cost would be $60.00.
