How many kilowatts to charge a Tesla? Details about charging

How many kilowatts to charge a Tesla? There’s an ongoing debate on whether electric vehicles REALLY save you money. With higher upfront costs, it’s more likely that a potential EV buyer will stick to his gas powered vehicle. Afterall, there’s not enough information about charging costs out there. Unlike gassing up at a petrol station where it’s easy to estimate prices, the electricity costs of charging EVs depend on a few factors.

How many kilowatts to charge a Tesla?

The amount of electricity required to charge a Tesla depends on the battery size and the charging speed. On an average, a Tesla Model 3 requires around 30 kWh to fully charge from empty to full. However, this can vary depending on the charging method and the model of Tesla.

How much does it cost to charge a Tesla?

On average, it costs $15.52 to charge a Tesla, based on the national average cost of electricity. Across all models, Teslas cost slightly less than 5 cents per mile to charge.

Across all product lines, the average charging cost of a Tesla is 4.56 cents per mile.

How many kilowatts to charge a Tesla

While, as we explain below, the cost of charging an EV depends on several factors, we’ve summarized what you can expect to pay for the various Tesla models. These numbers are based on the average cost of electricity in the U.S., reported by the EIA, which is approximately 15.64 cents per kilowatt-hour (kWh).

Keep in mind that the energy required to charge the battery pack (in kWh) is greater than the battery size because some of the energy used to charge the battery is lost during the charging process. We’ll explain this process in greater detail later on, but it’s important to note that these numbers are conservative based on data filed with the Environmental Protection Agency (EPA).

Cost to charge a Tesla Model 3

The Model 3 line includes compact sedans and is Tesla’s most affordable line of vehicles. It costs between 3.76 and 4.67 cents per mile to charge a Model 3 product. The Model 3 is Tesla’s cheapest product to charge.

Cost to charge a Tesla Model S

Offering mid-size luxury sedans, the Model S line includes Tesla’s longest-range vehicles. Cars in the Model S line cost 4.40 or 4.58 cents per mile to charge.

Cost to charge a Tesla Model X

Tesla’s Model X line includes mid-size SUVs. Model X vehicles are Tesla’s most expensive products to charge per mile at 5.17 or 5.40 cents per mile.

Cost to charge a Tesla Model Y

The Model Y line offers compact SUVs. While Model Y vehicles can’t travel as far as Model X vehicles, they are cheaper to charge at 4.31 or 4.75 cents per mile.

How much does it cost to charge a Tesla with solar energy?

Hoping to maximize your EV savings? The best way to do so is to power it with solar! On average, the return on investment for a solar system is about seven to eight years – meaning you’ll be paying less for your solar system than you would be for electricity from your utility at this point.

Given that a solar system will typically last between 25 and 30 years and a Tesla will generally last between 22 and 37 years (as explained in more detail below), installing solar along with your EV is worth the investment. In fact, once you’ve finished paying off your system, you’ll be generating electricity and charging your vehicle for free!

How much does it cost to fuel a gas-powered vehicle?

Gas prices are variable and largely dependent on your location; Hawaii and California have some of the highest gas prices while Texas has some of the lowest. Additionally, the cost of fueling a gas car vehicle depends on the size of the gas tank and the type of gas required.

How many kilowatts to charge a Tesla

You’ll also pay more for gas overall if your car is less efficient (meaning it travels a shorter distance per gallon of gas). We’ll explain how much it costs to fuel a compact car, luxury midsize car, midsize SUV, and compact SUV in 2023.

Honda Civic

The 2023 Honda Civic 4-door is a compact car with a 12.4-gallon fuel tank. It runs on regular gasoline ($3.418/gallon as of February 15, 2023, according to AAA), meaning it costs about $42.38 to fill up the tank. The Honda Civic is also fairly efficient, traveling at about 36 miles per gallon (combined city/highway), which provides 446 miles of range. Overall, fuel costs approximately 9.5 cents per mile for the Honda Civic.

Mercedes-Benz E-Class

The 2023 Mercedes-Benz E350 4matic is a luxury midsize car containing a 17.4-gallon fuel tank. This vehicle utilizes premium gas ($4.160/gallon as of February 15, 2023, according to AAA), which costs about $72.38 to fill up the tank. It travels at about 26 miles per gallon (combined city/highway) and can reach about 452 miles on one tank. Overall, for this Mercedes-Benz, fuel costs about 16 cents per mile.

Kia Telluride

The 2023 Kia Telluride AWD is a mid-size SUV and comes with an 18.8-gallon fuel tank. It takes regular gas and costs about $64.26 to fill up the tank. This vehicle can travel about 21 miles per gallon (combined city/highway), allowing it to go about 395 miles on one tank of gas. Overall, fuel costs about 16.27 cents per mile for the Kia Telluride.

Hyundai Tucson

The 2023 Hyundai Tucson AWD has a 14.3-gallon fuel tank. It uses regular gas, meaning it costs about $48.89 to fill up the tank. This car travels at about 26 miles per gallon (combined city/highway), reaching about 372 miles on one tank of gas. Overall, for the Hyundai Tucson, fuel costs about 13.14 cents per mile.

What’s the difference between an EV and an ICE vehicle?

EVs and gas-powered cars will both get you where you need to go, but there are a few key ways they differ. First and foremost is their fuel source. True to their name, EVs are powered by electricity, whereas gas vehicles run on gasoline, which is burned internally. We’ll explain the pros and cons of EVs compared to gas-powered cars and discuss how some popular brands vary in upfront cost.

EVs offer many benefits over gas vehicles, but there are some disadvantages you’ll want to be aware of as well. The pros of electric cars include:

  • EVs are energy efficient: a higher percentage of energy used to fuel an EV is converted to usable energy.
  • EVs reduce emissions: unlike gas vehicles, EVs don’t directly release carbon dioxide into the atmosphere. However, if you’re not powering them with clean energy, the electricity source used to recharge them may contribute to emissions (though still far less than a gas vehicle).
  • EVs have a lower cost of ownership: because EVs don’t have an internal combustion engine, the maintenance costs are often considerably lower than gas vehicles. Paired with savings compared to filling up a gas tank, it’s cheaper to drive an EV than a comparable gas vehicle.

Some cons of EVs you’ll want to consider are:

  • EVs generally can’t travel as far: an EV’s battery typically needs to be recharged before a similar gas vehicle would need its gas tank refilled.
  • EVs take longer to “refuel”: you’re probably used to filling up your car’s gas tank whenever it’s empty – EVs generally require a bit more planning. Even with the fastest EV charger, you should expect charging to take about 15 minutes. However, if you have an EV charger installed at your home, you’ll definitely need to make fewer trips to public chargers!
  • EVs generally have higher upfront costs: as we explain below, you may need to pay more upfront for an EV than a gas vehicle (but it could be less expensive in the long run). It’s also possible that you’ll need to replace the battery modules within your EV over the car’s lifetime, depending on how frequently you charge it and what temperature it’s stored at.

How much does it cost to charge a Tesla at home?

To begin, we will compare prices of each Tesla model based on the AC charging capabilities available to you at your abode. By using some relatively novel math, we can determine approximately what it may cost you to charge your Tessie on average in the US.

Then, you can use this math later to determine a more precise cost in your home state… if you want. The data used to approximate these costs was gathered from the US Energy Information Administration (EIA), which was last updated in August of 2021.

How many kilowatts to charge a Tesla

For the costs associated with charging from home, we used the US average costs for residential energy usage in cents per kiloWatt hour (kWh). This averages out to $0.1399 per kWh, but we will round up to $0.14 to keep things neat.

Additionally, we are using the current Tesla models listed on its website to figure the latest battery sizes and estimated range.

Tesla Model S

Both the Long Range and Plaid Model S feature a 100 kWh battery pack, a nice clean number to do our math with. So for 100 kWh of energy, you’re looking at $14, but not so fast! Remember our paragraph above, AC chargers are not perfectly efficient, so we must account for that in our equation.

Average efficiency rates for Level 1 and Level 2 AC chargers fall between 80-90%, so we will call it right down the middle at 85% efficiency. So where were we?

With a 100 kWh battery on the Model S at $0.14 per kWh, plus the 15% additional energy required due to inefficiency, it will cost approximately $16.47 to fully charge your Model S from 0-100%. Realistically, it should be less than that depending on your starting battery life.

Now, the Model S Long Range currently has an EPA estimated range of 405 miles, which means you’d be paying about $0.041 per mile or $4.07 for 100 miles of range.

The Model S Plaid has an estimated range of 396 miles, coming out to $0.042 per mile or $4.22 per 100 miles.

Tesla Model X

Like its older sedan sibling, both upcoming trims on the Model X feature a 100 kWh battery pack as well. Same battery size, same price – $16.47 to fully charge your Model X from 0-100%.

However, the Model X is a larger and heavier Tesla than the Model S and comes with a lower range, so let’s calculate cost per mile. First, the Model X Long Range, at an estimated range of 360 miles, will cost about $0.046 per mile and $4.58 for 100 miles of range.

For the speedier but lower range Model X Plaid, its 340-mile estimated range costs roughly $0.048 per mile and $4.84 per 100 miles.

Tesla Model 3

Let’s dig into the newer models next, beginning the cheapest Tesla to date, the Model 3. This Tesla gets a little more interesting because its trims vary in battery size. For instance, the Standard Range Plus Model 3 comes with a 50 kWh battery, while the Long Range and Performance versions sit upon a 82 kWh battery.

Let’s start with the smallest and go bigger. A 50 kWh battery on the Tesla Model 3 Standard Range Plus will cost approximately $8.24 to fully charge. Not too shabby.

With added battery comes range, but with added range comes additional charging. Longer charging means additional cost, so let’s calculate the Long Range and Performance trims. An 82 kWh battery will cost, on average in the US, $13.51 to go from 0-100%, accounting for an 85% charging efficiency.

Now, let’s talk mileage. The Long Range Model 3 offers an EPA estimated 353-mile range, which equates out to about $0.038 per mile and $3.83 every 100 miles. Performance trim on the Model 3 is not far behind at an EPA range of 315 miles, costing around $0.043 per mile or $4.39 per 100 miles.

Last but not least (unless we’re talking range) is the Standard Range Plus Model 3. Its 262-mile range will run you approximately $0.032 per mile and a very reasonable $3.15 for 100 miles of range.

Tesla Model Y

Until Cybertruck someday delivers, the newest Tesla to hit roads in the US remains the Model Y. Currently available in two trims, both the Long Range and Performance versions feature a 75 kWh battery.

That means it will cost a Model Y owner in the US approximately $12.35 on average to fully charge their Tesla.

To break it down in terms of mileage, the Model Y Long Range and its EPA estimated 326-mile range will cost roughly $0.038 per mile or $3.79 per 100 miles of range.

Additionally, the 303 miles of EPA range on the Performance version of the Tesla Model Y comes out to about $0.041 per mile or, better yet, $4.08 per 100 miles.

Cost to charge a Tesla Supercharger/DCFC

DC Fast Chargers get you back on the road fully juiced a lot quicker, but it may cost you more for the advantage of speed.

Again, these prices very much depend on where you’re charging, the rates during the time of charge, and how much energy you’re actually taking from the grid.

On average, commercial energy prices are cheaper in the US. However, Tesla’s Supercharger network doesn’t necessarily utilize commercial rates, and certainly doesn’t charge customers that low of a rate.

How many kilowatts to charge a Tesla

Like the residential numbers, we will again utilize data from the EIA for average energy costs in the US. However, to account for this upcharge present on DC Fast Chargers, we will add an additional $0.10 per kWh. As a result, we get $0.216 per kWh, so we feel safe rounding up to a cool 22 cents.

DCFC’s like Tesla Superchargers snag DC power directly without having to convert it for your EVs battery, making them much more efficient compared to Level 1 and 2 charging. Charging efficiencies range from around 90% to 99%, so for our estimates, we will call it 95%.

Tesla Model Y

This time we will start with the youngest and go from there. You know the drill by now; the Model Y features a 75 kWh battery. Multiply that by the average commercial cost of $0.22 per kWh, account for 95% efficiency, and you’re looking at a price of $17.21 to charge the Tesla on a Supercharger or DCFC equivalent.

Breaking it down in terms of mileage, the Long Range Model Y costs approximately $0.053 per mile or $5.28 per 100 miles.

On the other hand, a Performance Model Y will run you about $0.057 per mile and $5.68 for 100 miles of range.

Tesla Model 3

Moving on to the least expensive Tesla, the 50 kWh battery on the Standard Range Plus Model 3 will cost approximately $11.47 to fully charge, while the 82 kWh batteries on the other trims will run you about $18.82 each.

A Standard Range Plus Model 3 comes out to roughly $0.044 per mile and $4.38 for 100 miles of range. Meanwhile, the Performance Model 3 and its 315-mile range will cost about $0.060 per mile and around $5.97 for 100 miles.

Lastly, the 353 miles on the Long Range 3 equals out to approximately $0.053 per mile and about $5.33 per 100 miles.

Tesla Model X

Our last two Tesla models should go quickly as they both utilize a 100 kWh battery pack. That means in order to charge from 0-100%, accounting for 95% battery efficiency, it will cost approximately $22.95 to fully charge a Model X via DC Fast Charging.

Cost per mile is where things vary, however. The Long Range Model X comes is around $0.064 per mile and $6.37 per 100 miles, while the 340 available miles on the Plaid will cost roughly $0.068 per mile or $6.75 for 100 miles of range.

Tesla Model S

Both versions of the Model S also feature the 100 kWh battery (see above). That being said, let’s skip right through to the cost per mile.

The Long Range Model S comes out to $0.057 per mile and approximately $5.67 for 100 miles of range. With a lower estimated range, the Model S Plaid will cost you about $0.059 per mile and $5.88 per 100 miles.

What is the yearly cost of driving a Tesla?

If you calculate the average of all Tesla models, it costs $614.95 to charge per year. Comparable gas-powered cars cost an average of $1,850.42 to fuel per year. So, Teslas cost approximately $1,235 less to drive each year than gas vehicles.

This is calculated by using the average U.S. gas prices from AAA as of February 2023 and electricity prices from EIA data as of November 2022, along with the average distance driven according to the Department of Transportation (DOT) of 13,476 miles each year.

What factors impact the cost of charging a Tesla?

While charging a Tesla is almost always cheaper than filling up an ICE vehicle with gas, the price difference will depend on several factors. We’ll explain some of the major things to consider to maximize your savings when weighing your charging options.

How many kilowatts to charge a Tesla

Your electricity source

Because you use electricity to charge a Tesla, it’s no surprise that the biggest factor that will affect the cost of charging is your electricity source. For example, you may pay for your utility’s standard offering, or you might choose an electricity alternative, such as community solar, a community choice aggregation (CCA), or a green power plan (GPP).

Typically, community solar subscribers pay less annually to charge their Teslas. However, your utility’s standard offering might be cheaper than a CCA or GPP. To learn more about how these alternative electricity sources compare, be sure to check out this article.

If you’re really looking to generate savings, the best way to charge your Tesla is with a rooftop solar system: once you pay off your system, you’ll essentially be able to charge it for free!

The size of your Tesla’s battery

It’s no surprise that you’ll pay more per charge if your car has a larger battery capacity. However, depending on your Tesla’s range, you may still pay less per mile with a large battery, and you’ll also have to charge your vehicle less frequently.

The type of charger you use

When you charge your EV’s battery, not all of the energy you use is stored in the battery: some is lost as heat, some is used to keep the battery at an adequate temperature, and some escapes as “transmission loss” (a process that’s quite technical, so we won’t get into the details). The level of EV charger you use can substantially impact the amount of energy that’s lost as heat – higher voltage charging generally equates to less energy loss.

For example, Level 1 chargers (AKA 120-volt regular outlet chargers) and Level 2 chargers (AKA 208- or 240-volt standard home chargers) have to convert alternating current (AC) electricity from your home into direct current (DC) electricity that can be stored by your EV’s battery. This conversion produces heat, leading to energy loss.

On the other hand, using a Level 3 charger (400-volt chargers you’d find at public charging networks) is referred to as DC fast charging because they provide DC electricity, so no conversion losses occur. According to an article from Car and Driver, Level 3 chargers typically see efficiency above 90 percent, whereas Level 1 or Level 2 chargers typically reach about 85 percent, with some dropping to as low as 60 percent in cold weather.

Charging costs also vary if you opt to use one of Tesla’s Superchargers.

Where you live

Electricity costs vary significantly across the country, so where you live will play a large role in how much you pay to charge your Tesla (unless you’re charging it with solar energy!)

Overall, you’ll probably pay the most if you live in the Pacific Noncontiguous U.S. and the least if you live in the West South Central region of the U.S.

It’s also important to note that more energy is lost in the charging process if you live in a really hot or cold climate – energy will be used to keep your Tesla’s battery at an adequate temperature, leading to a lower charging efficiency. Thus, temperate climates are best for EV charging.

When you charge your Tesla

Depending on where you live, you may also pay more to charge your Tesla at certain times of the day. Certain utilities have rate structures that adjust the rate you pay for electricity over the course of the day or year, based on when electricity is in high demand.

These rate structures, called time-varying rates, will vary by utility but generally charge more when the cost of generating electricity and the demand for electricity is high – such as in the middle of the afternoon on a hot day. Typically, you’ll pay less to charge your Tesla after you’ve gone to bed if you live in an area with this type of rate structure.


How much does your monthly electricity bill go up with a Tesla?

According to 2022 data from the Department of Transportation (DOT), the average driver in the U.S. travels about 1,100 miles each month. Across all Tesla products, the average charging cost per mile is 4.56 cents per mile. So, if you stick to home charging, you can expect your electricity bill to increase by about $50 each month.

How long does it take to charge a Tesla?

Charging time depends on the type of charger you use; there are 3 levels of EV chargers and the charging speed increases with each. If you’re charging your Tesla at home, you probably have either a Level 1 (120-volt, standard outlet) charger or a Level 2 (208- or 240-volt) charger. You should expect a Level 1 charger to take between 20 to 40 hours to charge your Tesla, and a Level 2 charger to take about 8 to 12 hours.

If you’re planning on charging your Tesla on a road trip at a Level 3 charging station, such as a Tesla Supercharger network, it will probably only take about 20 to 30 minutes. To learn more about charging a Tesla, make sure to take a look at our article about the time it takes to charge different Tesla models.

How long do Teslas last?

In a 2019 tweet, Tesla CEO Elon Musk claimed that the Model 3 product line is “designed like a commercial truck for a million-mile life.” However, he estimates that the current batteries in the vehicles should last between 300,000 and 500,000 miles, or about 1,500 cycles – the number of complete charges. Assuming you follow the U.S. average and drive 13,476 miles annually, this means you can expect your Tesla to last between 22 and 37 years.

Above is information about How many kilowatts to charge a Tesla? that we have compiled. Hopefully, through the above content, you have a more detailed understanding of Cost to charge a Tesla Supercharger/DCFC. Thank you for reading our post.
