Electric Vehicle Costs


How Much Do EVs Cost to Buy?  

Electrical vehicles can run from $30,000 on the low end to over $100,000 on the high end, with Tesla being the major seller with 1,917,450 vehicles sold since it was first introduced.

Elon Musk who owns Tesla brought in a revenue of $53.8 billion for the year 2021. Aside from Tesla, other manufacturers jumped on the bandwagon to make electric vehicles such as BMW, Nissan, Chevrolet, Ford, Volkswagen, and Kia.

2023 Update: Most EV buyers are heading to Tesler over other manufacturers. According to one dealership, they had to lower the price of their EVs because “They are not selling”.


How Much Does It Cost to Charge an EV from Your House?

According to our calculations, it can cost between $10 – $15 per charge to the recommended 80% when your EV is near zero battery capacity, which equates to 230 miles. That is less than 1/2 the cost of what a conventional gas car would cost to drive the same distance. If your battery has more than zero juice, your electrical cost would be even less to reach the 80% – 230-mile range.

The cost to charge your EV depends upon several factors, but in general, expect to pay between $20 – $30 for a full charge, which is much better than a conventional gas car expense, since you can add a good 200 – 300 miles back to the battery. Try getting 200 miles for $30 on a conventional car!

Electrical Charging an EV

What is the Difference Between Level 1 and Level 2 Chargers?

There are some major differences. A level 1 charger can be plugged into any 110-volt outlet, but charges at about twice as long as a level 2 charger, which connects to a 220/240-volt outlet. If you recall our article on voltage, it is the amount of current that is ‘pushed’ out. Like a water faucet. The more you move the lever, the faster the water comes out. So a level 1 charger that uses 110 volts, the amount of current is, on average 15 amps. A level 2 charger can draw up to 60 amps, depending on the size of the breaker in the house.

Why are There Two Batteries in My EV?

Power Battery: The main battery is the EV battery, technically called the traction battery because it is the battery that provides the power to drive the car.

Auxiliary Battery: This battery is the standard ‘starter12-volt battery’ that we see in all cars (conventional gas and EVs).  The battery is responsible for powering auxiliary systems such as lights, radios, climate control, and all other electronics in the vehicle. Most importantly, it is the battery that is used for starting the car.

If you are in an EV and you press the Start button but nothing happens or weird things occur like flasing internal lights but the cat won’t start, it will be the auxiliary battery that is causing the problem. Not the EV battery.

How is Electricity Sent to the Car’s Devices?

The EV uses a DC-DC converter that converts the higher voltage of the EV battery, called the battery pack to the standard 12 volts needed to power the car’s internal electrical systems.

The actual term for the DC-DC converter is called a step-down converter, as it takes in the higher voltage from the EV and steps down the voltage to 12 volts.

How is the 12-Volt Battery Charged in an EV?

Electric vehicles do not have alternators, which are used to charge the 12-volt batteries in gasoline cars. For EVs, the process is the following:

  1. When the car is running, the DC-DC converter draws power from the high-voltage battery (the battery that drives the car) and converts it to 12 volts. This power is then used to keep the 12-volt battery charged.
  2. When the car is plugged into a charger (home or mobile), the charger takes over to power the DC-DC converter, which then charges the 12-volt battery.

How Long Does It Take to Charge an EV?

That depends upon the charger you are using. Currently, there are two types available. A Level-1 charger that connects to any 110-volt outlet. This can take over six hours to fully charge an EV’s battery.

Then there is a Level-2 charger. Charging of this type usually takes about three to four hours to reach full charge.

Shortly, Level-3, called high-speed chargers, will cut this charging time in half or more.

Does Fully Charging Mean It Charges Up to 100%?

No, all EV battery manufacturers agree that these batteries should not be charged to 100% because it will cause degradation of the battery in the long run. Charging to 80% is the recommended charging level and is usually set as the default for most EVs.

You can override this setting if you are planning a long trip but it is not recommended to keep it at the 100% charge level continuously.

So when we say we are fully charging our EV, it means that we have charged up to the 80% mark.

What if My Battery Goes to Zero Miles Left and I Am Sill on the Road?

Zero mileage does not necessarily mean your EV will stop in its tracks, but you should seek an EV station ASAP! Photo SS.

That’s why we recommend not to let your EV battery go below 30%, like the scenario we mentioned above, but we do understand that there are circumstances when this can happen. Chances are you will still have some power left to drive another few more miles. The mileage algorithms are not perfect and only give you an estimate of how much charge you have, but these estimates are fairly accurate as far as estimates are concerned,

When you see that warning notice on your dashboard, you should immediately shut down all accessories (radio, air conditioner or heater, phone charging, etc.) so that the least amount of power is being drained from the battery, but you should look for a charging station immediately!

The Weather and the Seasons

Do the Seasons Have an Effect on EV Batteries?

Yes, especially in winter. If the temperature goes below 40 F degrees, expect the mileage to diminish faster. Case in point: It was late November. A couple was leaving Manhattan to go to Long Island. Their GPS said it was a 27-mile drive and 45 miles were left on the vehicle, but halfway through their drive, the mileage counter dropped to 10 miles. Fortunately, they found an EV station along the way and were able to charge the car.

This is why we always suggest not letting your EV battery get that low. Once you see it is below 30%, you should charge it.

Can I Charge My EV in the Rain?

If the charger has protection such as non-conductive shielding at the port section, then you should be ok if the charger is left outside in the rain.

Check with your charging manufacturer to determine if your home charger is rainproof, but as with all electrical devices, it is always safer to keep these chargers away from anything wet.

Travel and Long Trips

How Many Miles Can I Get on a Full Charge?

Most EVs in the medium-cost range get about 230 miles on an 80% charge. The manufacturers do not recommend charging to 100% as it decreases the integrity of the battery.

Some of the higher ones, such as the Tesla Model S can get up to 394 miles when the batter is at full capacity. On the other hand, a Kia Niro, a great EV with excellent reviews will get about 253 miles on a full charge. And the 2023 Chevy Silverado will have a 200 kWh battery that can take you a good 400 miles before recharging.

Can I Go on Long Rides With My EV?

You can but it is not advisable at this time; however, if you are bent on taking long drives with your EV, it is highly recommended that you plan your trip with charging along the way as your main priority. Check the highway’s rest areas to see if they have charging stations, but be aware that if you do have to charge your EV during your trip, you may have to stay a while, possibly a good three to four hours at each station.

As President Biden’s infrastructure bill goes into effect, you will see more and more charging stations appear, especially along the highways, but remember, charging an EV is not like pumping gas into a car. You will be there for a few hours each time you charge your vehicle.

Of course, you don’t have to fully charge your car. If you could just add another 100-150 miles, that would cut down the time spent waiting. 

Either way, plan so that you can find places to go while the car is charging. Some of these locations may have a restaurant where you can have a long dinner or some towns may have charging ports on the street or in garages, or shopping mall parking lots. As you wait you can traverse through the many stores to kill time.

Then there are the hotels. Call ahead to find out if they have EV portals and if not, where is the closest one?

Shortly, more and more charging stations will be added along the highways and private locations such as housing and hotels. Additionally, in Biden’s Build Back Better plan, he has allocated $5 billion to increase the US infrastructure with over 500,000 new EV portals, and that doesn’t include the additions by private enterprises.

Tell Me More About the Mileage Estimates

A rideshare driver was on his way home from his last drop-off in Manhattan. He previously didn’t realize that the drive for this customer was further out than he thought and he saw that he had only 35 miles left on his battery.

Since he lived just outside the city limits in Long Island, he was sure that he would be able to get home before the battery capacity runs out. He was wrong. And this was during the warmer weather.

When the driver was on the highway, only 13 miles from his home, a warning light came on and said he had zero miles left to drive. What was saying 13 miles all of a sudden went to zero, meaning he had no more battery life in his car.

What happened to that missing 13 miles can only be explained by the fact that the mileage algorithms keep refreshing and new estimates materialize. So it is strongly advised to monitor your mileage with a give or take of 10- 15 miles either way. Thinking this way may help you decide when you should make your next charge.

This is especially true for winter driving as we have stated.

Plan Ahead!

If you are going to purchase an EV, plan out your expenses first against what it would cost for a gas car. Then plan out what you plan to do with the car. Will you be using it for local driving or going to work every day or is your main purpose going on long trips? At this current time, we would recommend that you purchase your EV for local driving or work. Whatever you choose, enjoy your ride!

What are the Advantages of Owning an Electric Car?

Of course, the main reason for owning an EV is the savings you get by not having to gas up your car, especially at the prices today. Additionally, EVs don’t have a combustion engine, so there are fewer parts to become defective during your ownership. EVs are said to help with the environment as well and they run very quietly.

What are the Disadvantages of Owning an Electric Car?

The initial expense of purchasing one is what keeps many who would otherwise buy one. Then there is the cost of having a 220-240 volt connection installed into your home circuit box, which can run from $600 to $1000. 

If you live in an apartment, you may run into an additional issue if the building or development you are in does not have an EV portal available, but more and more locations and communities are having EV stations installed such as shopping malls, public garages, and of course, many car dealerships.

Do EVs Need Oil Changes?

No. There are no combustion gas engines in electric vehicles, but cars with gas engines need maintenance. The oil used to keep the pistons running smoothly in the chamber of the engine needs to be changed every six months or 3,000 miles. Since no gas engine runs the car, no oil change is needed.

Why Electric?

There are a number of benefits of driving an electric vehicle (EV). One is the cost savings on gas. The other is the environment. We will concentrate on the former now and will talk about the environment in a separate article.

Before we start discussing how EV costs are calculated, make sure you have read our articles on the atom, electric current and Units of Power and How They are Related to Electricity so that you will be able to keep up with our cost calculations that involve knowledge about watts and kilowatts, but if you haven’t, no worries. You can skip to the bottom to get our estimate of EV electrical costs when charging from the home, or just read the review below. 


Here’s a brief overview for those who didn’t read the articles mentioned above.

    • Electrons are subatomic particles (one of the entities within an atom) that travel through the wire when power is applied (the wire is attached to an electrical socket). This is known as electrical current and is referred to in units of amps. More on this here.
    • Voltage is the force that pushes the electrons through the wireSimilar to turning on the pressure of a water faucet.
    • Current usually flows through a copper wire which is the conductor and the wire is covered by an insulator (rubber packaging around the wire so that the copper is not bear).
    • Resistance is the opposition to the current (electrons) that is flowing in an electrical circuit. Think of it as the friction that brushes along the side of the current.
    • A watt is the energy (power) that runs the electric device. It is a product of how much electrical current is running and how much voltage (push) is occurring. It is determined by multiplying the voltage times the current. The formula is E=IR (E=voltage, I=current, and R=resistance).
    • A kilowatt is 1000 watts (kW).
    • A kilowatt-hour (kWh) equates to 1kw that runs a device for 1 hour.

Example: If you run an air conditioner for one hour and that air conditioner uses 70 kilowatts of electricity per hour, then you have used 70 kilowatts of electrical energy for that hour. If you run the air conditioner for two hours, you would have used up 140 kilowatts of energy.

Most EVs, with the exception of the high-end luxury ones, have batteries that consist of a 60-65kWh capacity. Sparing you the formula, a battery of this size will equate to about 260 miles after a full (100%) charge.

Note: Most EVs are set to charge to 80% only. Constant charging to 100% diminishes the battery’s lifetime. 80% of a 65kWh battery equates to about 230 miles. 

How Do Kilowatts Relate to Electrical Costs?

Conventional Gas Cars

We will use a 2021, 4-cylinder Nissan Altima as our example.
Gas tank size: 16.2 gals and MPG: 31 average. 

If we multiply 31 miles/gals * 16.2 gals, we can determine the total mileage that this car can run on a full tank of gas, which is 502 miles.  

As of this writing, the price for a gallon of gas is $5.00 on average across the United States. So $5.00 * 16.2 gallons (a full tank) equals $81 to fill up.

Electrical Vehicles

For EVs, we calculate units per mile instead of MPG. For this example, we will use a 2020 Kia Niro EV, which is a fully electric vehicle and contains a 65kWh battery.

As mentioned, the industry standard for charging a 65kWh EV to 80% is about 230 miles.

Note: If you have an EV, never let it go below 30%, as you may run into trouble if you are on the road and can’t find a charging station, especially in the winter time.

Let’s review what we know so far:

    • Filling up a gas tank of a 2021 Nissan Altima will take you about 502 miles without having to fill up again.
    • The cost to fill up this car as of this writing is $81.00.
    • To charge a 2020 Kia Niro’s battery to 80%, the car can go about 230 miles without having to recharge.

Local Averages Using Electric Utility Calculations

We called PSEGLI directly to find out the average cost of electrical consumption for a typical home in Nassau County. Keeping it simple, an average home uses about $.33 per kWh (this includes delivery and service charges).

According to one source, 7.2 kWh is used each hour to charge the battery and if it takes approximately 4 hours to charge, the total kWh is 28.8 kWh.

28.8 kWh x $.33 = $9.5.

Rounded off, it costs about $10.00 to charge a 65kWh battery, which equates to 230 miles, but if you’d like to be a little more cautious if you think that might be too low (since there are so many variables involved that might not meet your particular driving habits or lifestyle, we can say the approximate cost for charging a 65kWh battery from a 220/240-volt level 2 charger is $15.00. How’s that?


We will now compare filling a gas tank of a conventional car which equates to the same mileage (230 miles).

Here are the steps: 

    • Divide the total mileage to charge the battery to 80% by the total mileage to fill a gas tank to get the percentage between the two: 

230 mi / 502 mi = 45% 

    • Multiply this percentage by the total cost to gas up a car: 

To get the cost for a conventional car to go 230 miles, we multiply the cost to fill up the gas tank ($81.00) by 45% to match the 230 miles, and that cost would be 0.45 *$85 = $38.7. 

Using an average of today’s gas prices ($5.00 as of today), it would cost a gas car $38.7 to go 230 miles of highway driving and an EV car would cost $15 to go the same distance (230 miles) in Nassau County, New York.

Note: As of October 2022, the price of gas fell to $3.5 / gallon, so proportioning this price, we get the cost to fill a gas tank to go 230 miles is – ($3.5 x 16.2) x 0.45 = $25.5, which is about 7 gallons of gas.

That’s still a savings of $15.5 for every 230 the gas car drives.

Cost of Charging an EV

Update: As of January 2023, PSEG and other utilities are now using disaggregation. A technique that breaks down energy utilization by appliance via AI computer algorithms. Below is an example of disaggregation of a common household’s individual energy usage by appliance.

Notice that $91 was spent on EV charging for the 30 days of November 11, 2022, to December 12, 2022. That’s $22.75 per week using standard electrical charges (not Time of Use as described below).

In comparison, one SUV that averages 25 MPG and traveled 1,100 miles for that same time period would have cost $149.60 at today’s price of $3.40 per gallon. Similarly, a typical mid-sized sedan traveling 1,100 miles would run $124.66.

You can calculate your specific mileage costs here.

Selective Electric Utility Plans Overview

Most electric utility companies provide more than one plan that you can select for your household. Besides the default plan which provides the same price for electric consumption 24×7, there is a plan that can allow you to select lower rates based on different times of the day.

This plan, called Time of Use (TOU) is available at PSEGLI and NYC’s Con Edison, as well as many other utility companies nationwide. Refer to their brochure as to exactly how this works.

If you have not already done so, change your plan to TOU and schedule your EV charging for after midnight on weekdays.

You can also apply the same schedule for your dishwasher, washer and dryer and any other appliance that uses electricity.


Take a look at the electric bill above from PSEG of Long Island (PSEGLI) above, which powers Nassau County and where the offices of Howard Fensterman are located.

Electrical power companies charge per kWh and we did some preliminary calculations starting with the delivery charges in the bill, and that doesn’t include the actual electrical costs after that.

Note: It can take up to four hours to charge an EV using a level 2 charger.

If you are looking to save money on gas, EV cars are the way to go. Yes, these vehicles are more expensive than conventional gas cars, but at $3,50 per gallon, you will be pleasantly surprised how much your savings can accumulate.

Finally, we leave you with this. Below is a copy of the estimated charges that accrued for the month of July 2022, from a 1,100-square-foot home that has an EV in its garage in Nassau County, NY. The family charges the car to its 80% capacity about three-four times per month. Notice that the cost in the Electronics category is only 10% of the total usage in the house. Something to think about!
