This tool is designed to help electric vehicle (EV) owners plan their charging times, estimate costs, and understand their vehicle’s range efficiency. Whether you’re charging at home, on the go, or planning for a long trip, this calculator provides valuable insights to manage your EV charging more effectively.
This tool calculates the estimated time required to charge your EV from your current battery level to your desired charge level. It also estimates the cost based on your electricity rate, calculates the total energy needed, and offers additional insights such as the average cost per mile.
1. How accurate are the charging time and cost estimates?Our calculator uses industry-standard calculations based on charger power, battery capacity, and efficiency. However, real-world factors like ambient temperature, charging efficiency, and fluctuations in power output may impact the actual time and cost.
2. What does kWh mean, and why is it important for EV charging?Kilowatt-hours (kWh) measure the total energy capacity of your EV’s battery. Knowing your battery’s kWh capacity is essential to estimate charging time and cost accurately, as it directly relates to how much energy you need to add to reach your target charge level.
3. Why are voltage and amperage shown for each charger type?Voltage and amperage determine the total power output (kW) of a charger, which influences charging speed. Different EVs and charging setups may use different configurations, and knowing these specifications can help you choose the appropriate charger for your needs.
4. How can I estimate the total cost of a full charge?By entering your battery’s size, electricity rate, and selecting a charger, you can get a good estimate of the total cost. You can input 0% as the current charge and 100% as the desired charge to simulate a full charge scenario.
5. What is Level 1, Level 2, and DC Fast Charging?
Our EV Battery Charging Time and Cost Calculator is designed to simplify the charging process for EV owners, providing clear and accurate estimates. Whether you’re new to electric vehicles or a seasoned driver, this tool offers practical information to make EV charging more affordable, efficient, and convenient.
Let this calculator be your go-to tool for planning charging times, costs, and energy needs, making every trip with your electric vehicle smooth and well-prepared!

Not yet. All PEVs can use Level 1 and Level 2 (non-Tesla) chargers. DC fast charging, however, is vehicle-specific and not available for all PEVs. If your PEV has DC fast charging capabilities, it has one of the three types of fast charging ports – CHAdeMO, CCS, or Tesla. Vehicles'' charging ports vary by auto manufacturer, so make sure to check which connector is compatible with your vehicle before charging.
Fortunately, many DC fast charging stations now provide multiple connector options in order to service as many PEVs as possible. You can check if a specific station has your vehicle''s connector in DOE''s Alternative Fuel Data Center''s station locator. Map of available public chargers.
In other ways, charging a PEV is different:
Amperage (amp) and kilowatts (kW) are two different metrics related to the rate of charging. In general, the higher the amps or kW, the faster a vehicle can charge. However, it''s important to recognize your vehicle''s capabilities and your needs.
Voltage (Volts): The measure of electrical potential. Like pressure, it measures how strongly electricity is being "pushed" through a circuit. Volts = watts / amps.
Amperage (Amps): The measure of the flow of electricity. Like volume, it measures how much electrical charge is moving past a given point in one second. This term is used when describing the amount of electric current that a circuit can provide. Amps = watts / volts.
Kilowatt (kW): The measure of electrical energy that is equal to 1,000 watts. A 50kW charger is five times more powerful than a 10kW charger. Using a water pipe analogy, it refers to how much water (or energy) is flowing through a pipe at any point in time.
Kilowatt-Hour (kWh): The measure of how much electrical energy flows (generally used or dispensed) over one hour. Using a water pipe analogy, you can think of kWh as the equivalent to how much water comes out of the pipe and into a bucket in one hour. The size of a PEV battery is measured in kWh, which describes the total energy capacity. If the useable battery capacity is 100 kWh, and the vehicle gets two miles per kWh, then the range would be 200 miles per charge. kWh = (kW × hours).
For public charging stations, payment is by credit card at the pump, by a mobile app, or a monthly subscription service. Some vehicles and chargers have a feature called "Plug and Charge" that lets you simply plug in, and it can automatically pay using your linked credit or debit card. Sometimes public charging is even free! If you charge at home, the cost will be included in your monthly electric bill, just like you pay for the electricity use of home appliances.
There may be federal, state, or utility incentives available for installing a level 2 charger, including required electrical upgrades. Visit DOE''s Alternative Fuels Data Center to search for current incentives for chargers.

It depends. The price of gasoline and electricity varies around the country, but it is typically cheaper to charge a PEV than to fill up a gas tank. Fueleconomy.gov''s fuel cost calculator is a great place to compare refueling costs of a plug-in electric vehicle that recharges at home with a gasoline vehicle. The calculator allows you to personalize fuel prices* and driving habits when comparing two vehicles. The results provide fuel cost comparisons by week, month, year, or over 10 years.
