Electric cars are charged using electricity, which is measured in kilowatts (kW) and kilowatt-hours (kWh). The cost of charging an electric car depends on several factors, including the type of charger used, the size of the battery, the electricity source, and the location and timing of charging. There are three levels of charging: Level 1, Level 2, and Level 3, with Level 3 being the fastest and most expensive option. On average, charging an electric car costs around $0.05 per mile, significantly lower than the cost of fueling a gas-powered car, which is about $0.13 per mile. While electric cars may have a higher upfront cost, they are generally more cost-effective in the long run.

What You'll Learn
Cost of charging at home
The cost of charging an electric vehicle (EV) at home depends on several factors, including the type of charger, the electricity cost, the car's battery, and your geographic location.
Types of Chargers
There are three types of chargers: Level 1, Level 2, and Level 3. Level 1 chargers use a standard 120V, AC outlet and are the slowest option, taking up to 40-50 hours to charge a battery electric vehicle (BEV) to 80% from empty. Level 2 chargers are the most common for home use and require installation by a qualified electrician. They can charge a BEV to 80% in 4-10 hours. Level 3 chargers, also known as DC Fast Chargers, are typically found in commercial settings and can charge a BEV to 80% in just 20 minutes to an hour.
Electricity Cost and Usage
The cost of electricity varies by location, and you are charged based on the kilowatt-hours (kWh) of electricity used. Electric cars charged at home typically use about 7,200 watts (W) of electricity, which equates to 408 kWh per month for an average driver. To calculate the cost, multiply your vehicle's kWh/100 miles by the electricity rate for the time of day you usually charge. For example, if your EV requires 40 kWh to recharge a fully depleted battery and the rate is 18 cents per kWh, it will cost $7.20 to recharge.
Battery Size and Driving Range
The size of your EV's battery and your driving habits will impact the cost of charging. The average electric car consumes 0.346 kWh per mile, or 34.6 kWh to travel 100 miles. The average American drives 14,000 miles per year, resulting in an average usage of 406.5 kWh of electricity per month.
Cost Comparison
Charging an EV at home is generally cheaper than fuelling a gas-powered car. The average cost of electricity is 16.19 cents per mile for EVs, compared to $0.13 per mile for gas. Additionally, electric vehicles are eligible for various incentives and rebates, further reducing the cost of ownership.
In summary, the cost of charging an EV at home varies depending on the type of charger, electricity rates, battery size, and driving habits. By understanding these factors and calculating the costs based on your specific circumstances, you can make an informed decision about the financial implications of owning an electric vehicle.

Cost of charging at public stations
The cost of charging an electric car at a public charging station varies depending on several factors, including the type of charger, electricity rates, location, time of day, and membership programs.
Public charging stations typically have fees that are higher than home charging costs. The cost of charging at a public station can vary depending on the type of charger and the electricity rates. For example, Level 2 charging stations, which are commonly found in public locations, offer faster charging speeds and can add about 25-30 miles of range per hour. The cost of Level 2 charging can range from $0.10 to $0.30 per kilowatt-hour (kWh), depending on factors such as electricity rates, time of day, and location.
On the other hand, DC fast chargers, which are often found at public charging stations, can charge an electric vehicle much quicker, typically taking about 20-40 minutes to reach an 80% charge. These chargers can cost between $0.20 to $0.40 per kWh, or even up to $0.50 per kWh, resulting in a higher overall cost for a full charge.
It is worth noting that some public charging stations offer free charging, especially in locations such as malls, hotels, and grocery stores. Additionally, many new electric vehicles come with a limited amount of free charging at public stations, and charging networks may offer subscription plans or membership programs to reduce charging fees for frequent users.
When considering the cost of charging an electric vehicle at public stations, it is important to keep in mind that the cost of electricity is generally more stable than the cost of gasoline, and electric vehicles often have lower fuel costs compared to traditional gas-powered cars.

Cost of charging at work
The cost of charging an electric car at work can vary between organisations. Some employers will install workplace charging points and offer free access throughout the day as an incentive for their employees. Others may set a paid tariff, which can be time-based to encourage sharing of charging stations. Some companies may offer a combination of the two, with free charging for a set period of time and a fee after this time to encourage employees to vacate charging spaces.
Charging an electric car at work is generally cheaper than charging at a public charging station. In the UK, the average cost for home charging is 32p per kWh and 48p per kWh for a public charging station. The cost of charging at work is likely to be similar to the cost of charging at home, although this will vary between organisations.
The cost of charging an electric car depends on several factors, including the car's battery size, the current state of charge, the max charging rate of the vehicle and the charger being used. The weather can also impact charging time. A typical electric car with a 60kWh battery and a 200-mile range would cost about £13 for a full charge at home in the UK. The same car would cost around £26 for a full charge at a public charging station.
It is worth noting that some automakers, such as Hyundai, Nissan and Tesla, may provide complimentary public charging at certain chargers. Additionally, public charging stations can be free, pay-as-you-go or subscription-based, with prices set by networks or property owners.
Overall, the cost of charging an electric car at work will depend on the specific policies and charging infrastructure implemented by the organisation.

Cost of charging by battery size
The cost of charging an electric vehicle (EV) depends on several factors, including the type of charger, the battery size and level of charge, the region, and the time of day.
The cost of charging an EV is directly related to the battery size, as larger batteries require more electricity to recharge. For example, the Nissan Leaf has a battery size of 39 kWh, the Ford Mustang Mach-E has 73 kWh, and the Polestar 3 Long Range has 107 kWh. The larger the battery size, the higher the cost of charging.
The cost of charging an EV at home can be calculated by multiplying the vehicle's kWh/100 miles by the electricity rate per kWh for the time of day. For instance, if an EV requires 40 kWh to recharge and the rate is 18 cents per kWh, the cost would be $7.20. This calculation provides the cost per 100 miles, which can be adjusted based on the battery size.
The cost of charging at public stations is typically higher than at home, with prices varying by region and charger type. Level 1 chargers are the slowest and cheapest, costing around $1 to $5 per hour, while Level 3 chargers are the fastest and most expensive, ranging from $10 to $30 per charge.
It's worth noting that some public charging stations offer free charging, and many EV manufacturers provide a limited amount of free charging at public stations. Additionally, charging networks often have subscription plans to reduce fees for frequent users.
The cost of charging an EV with a larger battery size will generally be higher, but this can be mitigated by taking advantage of off-peak rates, subscription plans, and free charging options.
