How Much Does An Electric Car Cost To Charge

Electric vehicles are becoming increasingly popular as an eco-friendly transportation alternative. However, many people are still unsure about the costs associated with owning and operating an EV. One of the most common questions asked is “how much does it cost to charge an electric car?”

While the answer varies depending on factors like the type of car, driving habits, and electricity rates, this article aims to provide the latest data on electric car charging costs in 2024 to help clarify the true expenses.

By breaking down ownership costs based on popular EV models and real-world charging situations, we’ll uncover the often surprising truth about electric car fueling compared to gasoline vehicles.

Understanding Electric Car Battery and Range

Before diving into charging costs, it’s important to have a basic understanding of EV batteries and driving ranges. Electric car batteries store energy from the electrical grid to power the vehicle’s electric motor. Their capacity is measured in kilowatt-hours (kWh), with larger batteries providing more range per charge.

Most electric cars sold today have battery packs ranging from 40 kWh to over 100 kWh in size. For reference, the best-selling Tesla Model 3 has a 54-75 kWh battery depending on configuration. The average new EV now has a battery around 65 kWh.

An electric car’s range, or the distance it can travel on a single charge, is dependent on numerous factors like battery size, driving conditions, speed, and use of climate control systems. The EPA estimates ranges at optimal conditions, with most new EVs achieving somewhere around 200-300 miles per charge currently. Tesla vehicles regularly top 250+ miles of range.

Charging Your Electric Car: Types and Speeds

There are three main electric vehicle charging types available:

  • Level 1 (120v): Uses a standard 120v outlet and provides 2-5 miles of range per hour of charging. This is the slowest method but can be convenient with an included mobile connector. Effective for topping off overnight.
  • Level 2 (220v): Requires a 240v outlet and dedicated charging station. Provides 10-20 miles of range per hour of charging. Most common public and home charging setup as it’s faster than Level 1.
  • DC Fast Charging (480v): High-powered charging stations that can add 100+ miles of range in 30 minutes or less. Only option for long-distance travel but maximum battery health is maintained with slower Level 2 charging when possible.

While Level 2 home charging overnight is sufficient for most drivers, public fast charging networks have expanded rapidly in recent years to support longer trips. As of 2024, the US has over 45,000 DC fast chargers available nationwide according to Department of Energy data.

Calculating Cost Per Mile To Charge An Electric Car

With an understanding of EV range and charging types out of the way, let’s dive into the key question – how much does it cost per mile to charge an electric car? The best way to estimate this is by calculating costs based on the national average electricity rate.

In 2024, the average US residential cost per kWh of electricity is $0.14 according to the EIA. This rate will differ depending on your local utility provider and state, with prices ranging from $0.10-0.20/kWh nationally.

Let’s use a real example of the popular Chevrolet Bolt EV:

  • Battery size: 66 kWh
  • EPA rated range: 259 miles
  • Calculated kWh needed per mile: 0.25 kWh/mile (66 kWh battery / 259 miles of range)

To determine the cost per mile to charge this Chevy Bolt:

  • National average electricity rate: $0.14/kWh
  • KWh needed per mile: 0.25 kWh/mile
  • Cost per kWh: $0.14
  • Cost per mile = KWh/mile x Cost/kWh
  • Cost per mile = 0.25 kWh/mile x $0.14/kWh = $0.035/mile

So based on average electricity rates, it costs approximately $0.035 in fuel to drive one mile in a Chevy Bolt EV charged at home. That’s orders of magnitude less than the current national average gasoline price of $4.80 per gallon!

Let’s compare this to fueling a gas-powered car getting an average of 25 mpg:

  • Gas price: $4.80/gallon
  • MPG: 25 mpg
  • Cost per gallon: $4.80
  • Cost per mile = Cost/gallon / MPG
  • Cost per mile = $4.80/gallon / 25 mpg = $0.192/mile

As you can see, fueling an EV using residential electricity rates costs roughly 6x less per mile than driving a comparable gasoline vehicle. And this analysis doesn’t even factor in potential additional home charging savings from renewable electricity plans or time-of-use rates.

Real-World Charging Cost Data

To corroborate these estimates, many EV owners share their real-world charging costs based on driving history tracked by their vehicles. Here are a few typical examples:

Tesla Model 3 Owner Data:

  • 18,000 miles driven in one year
  • Average total kWh usage: 1,200 kWh
  • Actual cost at $0.12/kWh rates: $144/year or $12/month

Chevy Bolt Owner Data:

  • 12,000 miles driven
  • Total kWh used: 800 kWh
  • Actual cost at $0.10/kWh rates: $80/year or $6.67/month

Nissan Leaf Owner Data:

  • 25,000 miles driven in two years
  • Approx. 2,000 kWh used over that period
  • Actual cost at $0.13/kWh rates: $260/year or $21.67/month

As you can see, real EV driver data very consistently matches the estimates shown earlier. Most electric vehicles cost between $50-150 per month to charge depending on various usage factors. The key takeaway is EVs are very affordable to fuel at current electricity rates for many drivers.

To make these costs more relatable, let’s calculate estimated annual charging expenditures based on average annual mileage:

  • Average American drives 13,500 miles per year according to the DOT
  • Tesla Model 3 Long Range (315 miles EPA range):
  • Electricity needed annually: 13,500 miles / year x 0.3 kWh/mile = 4,050 kWh
  • Cost at $0.14/kWh = $568 per year
  • Ford Mustang Mach-E Extended Range AWD (270 miles EPA range):
  • Electricity needed annually: 13,500 miles / year x 0.33 kWh/mile = 4,455 kWh
  • Cost at $0.14/kWh = $624 per year
  • Nissan LEAF Plus (226 miles EPA range):
  • Electricity needed annually: 13,500 miles / year x 0.38 kWh/mile = 5,130 kWh
  • Cost at $0.14/kWh = $719 per year

So for the average annual US mileage, fueling a popular mid-size or full-size electric car at home using household electricity costs between $568-719 per year. Even factoring in occasional fast charging on long trips, total annual fuel costs are still far below the over $6,500 it would cost annually to fuel a 25 mpg gas car.

Public Fast Charging Cost Comparisons

While home charging is ideal, public fast charging networks are crucial for enabling long road trips in an EV. Here’s a look at costs for DC fast charging sessions at some of the major networks:

  • Electrify America: $0.31-0.43 per kWh depending on membership, usually providing around 80 miles of range in a 30 minute session.
  • Charge point: Pricing varies by location but averages $1-3 flat fee plus $0.25-0.50/kWh.
  • Tesla Superchargers: $0.28-0.31/kWh with no membership required for Tesla owners.

Based on these rates, fast charging a 65 kWh EV battery from 10-80% will typically cost $15-30. While more expensive than home charging, fast charging still comes out cheaper than a gas fill-up between destinations. And as more public chargers come online, competitive rates are helping to keep EV road trip costs reasonable.

Potential EV Incentives and Additional Savings

There may be additional cost offsets for electric car owners beyond just lower fuel expenses. Many states and electric utilities provide incentives that can significantly discount the price of a new EV or installation of home charging hardware:

  • Federal tax credit: Up to $7,500 available for new EV purchases depending on manufacturer.
  • State rebates/grants: Programs in CO, CA, NY, NJ provide $1,000s more in incentives.
  • Utility EV rates/rebates: Programs like Time-of-Use pricing and home charger rebates cut costs.

Estimated maintenance costs are also lower for EVs versus gas cars. With fewer moving parts, electric motors require less servicing and no oil changes. Tire and brake pad replacements may be needed less often due to regenerative braking.

Average annual maintenance on an EV is around $500 versus $701 for a comparable gasoline car according to a 2023 Consumer Reports analysis. Over the lifetime of owning an EV, total savings on fuel and maintenance can easily top $10,000 or more compared to driving a similar gas-powered car.

tips and strategies to reduce the cost of charging your electric vehicle

Charge at home using a 240V outlet or charger whenever possible. Residential electricity rates are far cheaper than public charging. Take advantage of off-peak/overnight charging if your utility offers time-of-use rates. Prices are lowest during non-demand hours.

Keep the battery charge between 20-80% whenever you can rather than draining it low. This improves efficiency. Make small, frequent charges instead of fewer large charges to the maximum level. Topping up uses less total kWh.

Consider an EVSE charger with software that allows scheduling and delayed start times. Use public fast chargers only when needed on long trips, not for daily commutes. Stick to level 2 otherwise. Drive conservatively – acceleration and temperature control affect range and charging needs.

Check if your state offers electric vehicle rebates or incentives for home chargers. Ask your employer about installing workplace charging, even for a small rebate or subsidy per charge.

Debunking Common Myths About Electric Car Charging Costs

As with any emerging technology, there are still several misconceptions circulating regarding EV charging that warrant addressing:

Myth: Charging an EV at home will increase electricity bills significantly.
While charging does use extra power, the EIA estimates it adds only about $100-200 per year to average household utility bills. Even during peak hours, rates are still far below gas costs.

Myth: Public fast charging is too expensive to use regularly.
Most drivers charge 80-90% of the time at home and only use fast charging temporarily for long trips. When broken into costs per mile driven including home charging, EVs remain very affordable to fuel.

Myth: EV batteries must be replaced frequently, adding huge repair costs.
Most EV batteries come with 8-year, 100,000-mile warranties and are expected to retain 70-80% of their capacity even after 15 years of use. Replacement usually isn’t needed within the lifespan of most vehicles. Cost is also coming down quickly.

Myth: Charging an EV takes all day or night.
Most EVs can charge from 10-80% in 30-60 minutes using a fast charger. Home Level 2 charging fills the battery in 4-8 hours which occurs overnight during sleeping hours. Time spent charging is less than time spent at gas stations.

Myth: Public chargers are always broken or in use.
While availability varies by location, data shows over 90% of public fast chargers work properly. Usage also remains low for most networks. Apps help locate idle stations for quick fueling.

What are some other factors that can affect the cost of charging an electric car?

Temperature – Heating or cooling the cabin while charging uses additional battery power. Cold weather reduces EV range more than hot weather. Driving style – Aggressive acceleration and high speeds lower the efficiency and increase energy usage per mile driven.

Charging locations – Public fast chargers have higher kWh costs than home charging. Destination chargers are sometimes free. Battery degradation – Over time and miles, the battery capacity shrinks a small percentage each year, requiring slightly more kWh to travel the same distance.

Charging equipment maintenance – Well-maintained cords, connectors, and chargers transfer energy most efficiently without losses. Worn parts raise kWh needs.

VW e-Golf owner data: 10,000 miles/year, 750 kWh/year used, $0.08/kWh with time-of-use plan, $60/month average

What are some proactive steps that EV drivers can take to lower their charging costs?

Sign up for demand response programs from utilities – They pay drivers to charge off-peak in exchange for limiting power on high use days. Find commercial property to charge at – Many businesses offer free Level 2 charging to attract customers while they shop/work.

Ask your employer about workplace charging – Having a dedicated stall cuts out the need for public charger fees. Travel more efficiently – Use adaptive cruise, plan routes to minimize stops/miles, don’t overuse climate controls.

Total Cost of Ownership Comparisons

When debating whether an EV is financially viable compared to a gas-powered car, it’s important to consider the total cost of ownership over 5 or more years rather than just the initial purchase price. Some key factors that influence long-term costs include:

  • Fuel/Energy Costs – EVs are far cheaper to “fill up”, saving drivers thousands over the life of the vehicle versus gas.
  • Maintenance Savings – EVs have fewer moving parts so maintenance tends to be cheaper, especially eliminating oil changes and engine/transmission repairs.
  • Tax Incentives – Federal and local EV purchase rebates lower the upfront investment significantly in many cases.
  • Insurance Savings – Statistics show collision claims are lower for EVs, so premiums may be slightly cheaper on average.

When accounting for all these ongoing expenses in a detailed TCO (total cost of ownership) analysis, studies consistently show EVs reaching cost parity with comparable gas cars within 3-4 years, then becoming decisively cheaper options long-term.
