The cost of running an electric vehicle (EV) is a common concern for those considering making the switch from petrol cars. WhichEV has examined the typical cost differences between EVs and petrol cars, as well as the cost of charging at home versus charging in public.
In general, EVs are cheaper to run than petrol cars. Charging at home is also less expensive than charging in public, and charging during off-peak hours, such as in the early morning, is even cheaper. Additionally, those with solar panels and home batteries will pay the least for charging their EVs.
The type of car you choose will also affect the cost. Newer EV models have larger batteries and more efficient power trains, which indicate the direction future cars will take as EV technology continues to improve. Larger batteries allow for cheaper charging at home overnight.
Battery capacity is measured in kilowatt hours (kWh). When you charge an EV, you pick up a certain number of kilowatts while plugged in. The charging speed can vary, but for charges up to 80%, you can estimate the approximate charging time by dividing the amount of battery that needs to be filled by the speed of the charger. Let’s use a 61.7 kWh battery in a car like the MG4 Long Range, which provides a range of 281 miles on a combined WLTP cycle, as an example.
When charging in public, time is usually a priority as you want to complete your journey. Therefore, we will focus on fast/DC chargers rather than slow/AC chargers. Public charging prices can vary, but let’s assume a cost of 60p per kWh and a charger capable of delivering a steady 100 kW. Filling a 61.7 kWh battery at this rate would cost around £37.02. Most drivers primarily travel in urban areas and on smaller A roads, where you’re likely to get close to 270 miles on a charge. To match the range of a petrol car, you would need to add up to 25% more charge, which would cost an additional £9.23, bringing the total to £46.28.
For home charging, there are various “overnight saver tariffs” available. Let’s use a rate of 9.5p per kWh for 7 hours, assuming a proper home charger with a capacity of just over 7 kW. Starting from empty at midnight, you would pick up 49 kWh at a cost of £4.65. Then, you’ll need to finish with the remaining 12.1 kWh at a rate of around 30p each, once your overnight rate expires. This brings the total cost of a full charge to £8.28. If you want to balance the ranges, you would need to pick up an additional 15 kWh on the second evening, which can be done overnight for £1.43.
Comparing the costs over a 330-mile range, petrol would cost around £77.50, expensive public charging would cost £45, and home charging with a suitable overnight tariff could cost as little as £9.71.
Looking at the cost per mile, petrol would be around 23p, public charging would be around 14p, and home charging with a suitable tariff would be as low as 2.9p (specifically with E-On).
These calculations clearly show the potential savings with an EV. However, it’s important to note that electricity prices can be volatile, and it’s essential to do your own calculations and shop around for the best tariff that suits your lifestyle. Prices can fluctuate, so this comparison serves as guidance only.
It’s worth considering that while electricity prices are currently high, these elevated figures may not be a permanent state. The pricing connection between pure electricity from renewable sources and fuels like gas is artificial, and changes in production, new technologies, and improvements in solar generation systems and home batteries could lead to significantly lower electricity prices in the future.
Overall, despite the current high electricity prices and lower petrol costs, the cost of fuel for an EV remains a fraction of the cost of burning petrochemicals. Additionally, public charging can be up to 5x more expensive than home charging overnight.
Before committing to an EV, it’s essential to conduct your own calculations and find a tariff that suits your needs. Prices are subject to change, so it’s crucial to stay informed.
Comparing the Expenses of Driving: Gasoline, Public Transportation, and Home Charging
In our fast-paced world, transportation plays a fundamental role in our daily lives. Deciding on the most cost-effective means of getting from point A to point B is vital, particularly when it comes to managing our finances. Therefore, it is important to examine and compare the expenses of driving, including gasoline costs, public transportation fares, and home charging for electric vehicles.
Gasoline costs have long been the primary concern for drivers. As the most common fuel for traditional vehicles, gasoline prices can have a significant impact on our wallets. The cost of gasoline varies depending on location, demand, and geopolitical factors, making it a volatile expense. According to the United States Energy Information Administration, the average price of gasoline in the United States in March 2021 was around $2.83 per gallon. However, it is important to note that these prices fluctuate and can rise considerably during times of instability. Therefore, driving a gasoline-powered vehicle can result in varying expenses over time.
On the other hand, public transportation offers an alternative that helps mitigate the unpredictable costs associated with gasoline. Public transportation systems, such as buses, trains, and trams, usually operate on fixed fare structures that are set by local authorities. These fares are designed to provide affordable transportation options to the public, regardless of fuel price fluctuations. However, it is important to consider that public transportation fares can also vary depending on the distance traveled and the type of ticket purchased. Monthly and annual passes often provide discounted rates for frequent travelers, making public transportation a cost-effective option for those who rely on it daily.
The rise of electric vehicles (EVs) has introduced a new paradigm for transportation expenses in recent years. EVs offer the advantage of being powered by electricity, which typically costs less than gasoline. Home charging for EVs allows vehicle owners to take advantage of lower electricity rates during off-peak times, contributing to further cost savings. According to a study by the Rocky Mountain Institute, driving an electric vehicle can result in a 40-60% reduction in energy costs compared to driving a gasoline vehicle. This not only lowers the overall expenses associated with driving but also contributes to a cleaner and more sustainable environment.
While home charging for EVs appears to provide significant savings, it is important to consider the initial investment required to own an electric vehicle. EVs tend to have a higher upfront cost compared to traditional gasoline vehicles, often due to expensive battery technology. However, it is worth mentioning that government incentives and tax credits are available in many countries, helping to offset these initial costs and make electric vehicles more accessible.
When comparing the expenses of driving, it is crucial to take into account not only the direct costs of fuel or transportation fares but also any additional costs associated with ownership, such as maintenance, insurance, and parking fees. These additional expenses can vary greatly depending on the vehicle type, geographical location, and personal circumstances. Therefore, it is important for individuals to carefully evaluate their unique situations before making a decision.
In conclusion, evaluating the expenses of driving involves considering several key factors, including gasoline costs, public transportation fares, and home charging for electric vehicles. Gasoline prices are volatile and subject to geopolitical factors, making them unpredictable. Public transportation offers fixed fares, providing a more stable cost structure. Electric vehicles powered by home charging offer the potential for significant cost savings in the long run, although initial investment costs remain a factor to consider. To make an informed decision, individuals are advised to assess their unique circumstances and weigh the relative advantages and disadvantages of each option.
