EV Car Charger Energy Calculator (Cost and kWh Usage)

EV Electric Vehicle Charger

Electric vehicles (EVs) are becoming more and more popular around the world as people become increasingly aware of the impact of transportation on the planet. With EVs comes the need for EV car chargers, which can be installed in homes, offices, and other locations. In this article, we will discuss the energy consumption and costs associated with using an EV car charger, as well as provide money-saving tips for users of this appliance.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

The energy consumption of an EV car charger depends on a few factors, including the power of the charger and the amount of time it is used. The default power of the charger used in this article is 2000 watts. For example, if you charge your electric car for 4 hours per day, the total energy consumption would be:

2000 watts x 4 hours = 8000 watt-hours (Wh) or 8 kilowatt-hours (kWh)

It is important to keep in mind that other factors, such as the speed of charging, can also affect energy consumption. Some chargers can provide a faster charge, which can lead to higher energy consumption.

Importance and Relevance

Using an EV car charger is an important step in reducing carbon emissions and helping to combat climate change. As more people switch to electric cars, the demand for EV car chargers will continue to rise. Cost is another important factor – understanding the energy consumption and costs associated with using an EV car charger can help individuals make informed decisions about their energy usage and overall expenses.

Cost in Dollars of Energy Usage

Calculating the cost of electricity usage is relatively simple. The formula to calculate the cost of electricity is:

(cost per kWh) x (total energy usage in kWh)

Using the default energy price of $0.12 per kWh, here are some examples of the daily, monthly, and yearly costs of using an EV car charger:

  • Daily: 8 kWh x $0.12 = $0.96
  • Monthly: 8 kWh x $0.12 x 30 = $28.80
  • Yearly: 8 kWh x $0.12 x 365 = $350.40

Keep in mind that these costs may vary depending on the energy price in your area, the power of your charger, and the amount of time you use the charger.

Money Saving Tips

There are several ways to save money on energy costs when using an EV car charger. Here are a few tips:

  • Charge your car during off-peak hours when energy rates are lower.
  • Install a smart charger that can automatically adjust the charging rate to take advantage of lower energy rates.
  • Consider using a time-of-use plan or a fixed-rate plan to better manage your energy usage and costs.
  • Maintain your car’s battery to ensure maximum efficiency and reduce charging time.
  • Consider installing solar panels or using a renewable energy source to power your charger.

By following these tips, you can reduce your energy costs and help to reduce your carbon footprint.
