Published on
March 18, 2024

With their sleek designs, whisper-quiet rides, and eco-friendly creds, electric cars are the superheroes of the modern road. But, like any good superhero, they have their source of power: electricity. And as more drivers make the green switch, one question rises to the forefront: "How much electricity does an electric car actually use?"

Fear not, dear reader, for you've plugged into the right place. In this electrifying exploration, we'll demystify the sparks behind the scenes. From the daily commutes to the adventurous road trips, we'll journey through the ins and outs of eco-friendly car energy consumption. Whether you're a proud electric vehicle (EV) owner or just EV-curious, understanding these green machines is key to embracing the future of driving.

Factors Influencing Electric Car Electricity Usage

Much like choosing a favourite ice cream flavour, every green car has its own blend of characteristics that influence its electricity appetite. To peel back the layers of this electrifying onion, let's start with the basics. 

The electricity consumption of an electric car is typically measured in kilowatt-hours per hundred miles (kWh/100 miles) or kilometres. This metric gives us a glimpse into the efficiency of an EV, much like miles per gallon (mpg) does for their petrol-guzzling cousins.

But here's where it gets juicy: the average electricity usage can swing dramatically based on a medley of factors. For instance, a sprightly city car like the Nissan Leaf might sip electricity more modestly compared to a powerhouse like the Tesla Model S, which, when unleashed, can devour a more substantial chunk of energy to deliver its breathtaking performance.

Moreover, how much electricity an electric car uses is also affected by your driving style. Gentle accelerations and embracing the art of regenerative braking can make your EV more efficient. On the flip side, channelling your inner speed demon with rapid accelerations and high-speed cruising can see your usage spike faster than a hit song on the charts.

How Much Electricity Does an Electric Car Use on Average?

When it comes to unravelling the mystery of "how much electricity does an electric car use?" or pondering over "how many kilowatt hours to charge an electric car?", the plot thickens as we consider the day-to-day life of an average EV driver. The typical electric vehicle driver might see their EV consuming somewhere in the ballpark of 250 - 400 (kWh) per month. [1] This, of course, is a broad stroke, as real-world figures can be as diverse as the vehicles and drivers themselves.

Let's break it down further: An average electric car may boast an efficiency of about 4 miles per kWh. Considering this, a driver who covers the national average of about 12,000 miles a year would have a total annual consumption of approximately 3,000 kWh. [2] To put that into perspective, this is akin to the yearly energy appetite of a typical household's central air conditioning system in some climates.

Seasonal variations add another layer of complexity to the equation. The crisp embrace of winter can see your EV's consumption rise by up to 15-20% as the battery and cabin heating systems work overtime to keep both you and the car's internals at optimal temperatures. Conversely, the opposite is also true; your EV will be more efficient on a mild spring day as opposed to a hot summer day. 

Common EVs in the UK and Their Electricity Consumption: How Many kWh to Charge an Electric Car?

As we said before, there's no cookie-cutter answer to the question of "how many kilowatts to charge an electric car?" However, we can make it somewhat easier for drivers to understand their electricity usage by telling them about the consumption of the three most popular green vehicles in the UK. 

1. Nissan Leaf

The Nissan Leaf, often hailed as the poster child of the EV revolution, offers a practical and affordable gateway into electric mobility. With a battery capacity that hovers around 40 kWh for the standard model, fully charging a depleted Leaf would require approximately the same amount of electricity. Moreover, the vehicle ensures an efficient journey, typically consuming around 4.5 miles per kWh, making it a stalwart companion for the eco-conscious driver.

Bear in mind that with each charge, an EV's battery degrades slightly, so it's worth learning about how long Nissan Leaf batteries last in our comprehensive guide.

2. Tesla Model 3

The Tesla Model 3, with its sleek design and high-tech allure, drives into the future with an energy consumption that's as impressive as its acceleration. Depending on the variant, the Model 3's cell capacity can range significantly, but a standard 75 kWh battery is a common choice. This means a full charge from empty might need up to 75 kWh, but in return, it offers an energy-efficient ride of about 4 miles per kWh. 

Also, check out our discussion on the best tyres for the Tesla Model 3 to ensure you make your drive as efficient as possible.

3. BMW i3

The BMW i3, with its futuristic aesthetics and commitment to sustainability, not only turns heads but also spins the energy metre at a different pace. With a smaller battery capacity of around 42 kWh, it offers drivers an urban-friendly efficiency of approximately 4.1 miles per kWh.

If you're considering purchasing this EV, you should read our charging guide for the BMW i3.

How Much Does It Cost to Charge an Electric Car?

Hopefully, by now, you have a general understanding of how much electricity your EV is using. Naturally, the next question becomes, "How much will it cost to charge an electric car?" The financial aspect of charging is highly crucial, as it not only impacts your wallet but also influences the broader adoption of green vehicles. 

It is important to note that the cost to charge an electric car can vary widely, influenced by factors such as your local electricity rates, the time of day you power (peak vs. off-peak hours), and even the charger's efficiency. But fear not, for we can still shed some light on the cost conundrum with a bit of simple maths and some average figures.

Consider the average electricity price in the UK, which, for the sake of simplicity, we'll peg at around 29 pence per kWh (though this can fluctuate). [3] If you're driving a Nissan Leaf with a 40 kWh battery to the brink of depletion, a full charge would, therefore, set you back about £11.60. On the other hand, the Tesla Model 3, with its larger 75 kWh battery, would cost approximately £21.75 to charge from empty to full. And the BMW i3, cosy in the middle with a 42 kWh battery, would cost around £12.18 for a complete recharge.

But what does this mean in the grand scheme of things? If we circle back to our earlier exploration of average electricity usage, we can start to paint a picture of monthly and yearly costs. For an EV driver averaging 300 kWh of consumption per month, you're looking at a monthly charging bill of around £87. [4] This translates to an annual cost of about £1044, a figure that starkly contrasts with the fuel expenses of traditional petrol or diesel vehicles.

To further contextualise, let's compare it to household expenses. The monthly charge for powering your EV could be likened to a month's worth of coffee for a diligent espresso enthusiast or a couple of fancy dinners out. [5]

6 Tips to Maximise EV Efficiency and Reduce Energy Use

Embracing EVs not only contributes to a more sustainable environment but also offers a unique driving experience. However, maximising the efficiency of your EV and reducing energy consumption requires a bit of knowledge and some proactive steps. So, whether you're a new owner or considering making the switch, understanding how to optimise your vehicle's performance can lead to significant savings and a smoother ride.

Keeping to the above best practices will indeed help you get the most out of each kWh. However, there is one other highly effective strategy that is a game-changer for electric vehicle owners: top-up charging. 

Top-up charging isn't about waiting for your battery to flash warning signals of depletion before plugging in. By charging your EV during shorter, more frequent intervals – say, while shopping at the supermarket, parked at the office, or even during a quick stop at home – you maintain a higher average battery level. This approach not only sidesteps the need for prolonged powering sessions but also keeps you ready for impromptu journeys, ensuring that range anxiety becomes a thing of the past.

Moreover, top-up charging can also lead to financial savings. Utilising public points during off-peak hours or taking advantage of free powering facilities offered by some businesses and shopping centres can reduce the cost. In addition to this, maintaining your battery at moderate charge levels can help prolong its overall lifespan, safeguarding your investment in the long run.

To further contextualise, let's compare it to household expenses. The monthly charge for powering your EV could be likened to a month's worth of coffee for a diligent espresso enthusiast or a couple of fancy dinners out. [5]

6 Tips to Maximise EV Efficiency and Reduce Energy Use

Embracing EVs not only contributes to a more sustainable environment but also offers a unique driving experience. However, maximising the efficiency of your EV and reducing energy consumption requires a bit of knowledge and some proactive steps. So, whether you're a new owner or considering making the switch, understanding how to optimise your vehicle's performance can lead to significant savings and a smoother ride. 

Here are six tips to help you get the most out of your electric vehicle, ensuring you enjoy the benefits of EV ownership to its fullest.

1. Smooth Driving

Adopting a smoother driving style is a straightforward strategy to reduce how much electricity an electric car uses. Gentle accelerations, gradual decelerations, and utilising regenerative braking efficiently can lead to major energy savings.

2. Considerate Climate Control

The heating and air conditioning systems in your EV are significant energy consumers. To save electricity, precondition your car while it's still connected to the charger, which pre-heats or cools the cabin without using the battery's stored energy. Furthermore, on days with mild weather, using ventilated seats or opening windows can help maintain comfort without heavily relying on the HVAC system.

3. Reducing Unnecessary Weight

Carrying extra weight in your automobile can lead to increased power consumption. Regularly removing unneeded items from your car can lighten the load, helping to decrease how much electricity your EV uses. Simply put, keeping your EV as light as possible ensures better efficiency on the road.

4. Tyre Maintenance

The condition and type of tyres on your EV can also have a huge impact. To this end, opting for low rolling resistance sets specifically designed for electric vehicles can enhance battery life. Additionally, keeping tyres inflated to the manufacturer's recommended pressure is crucial for minimising energy loss and extending your driving range.

5. Optimised Routing

Choosing your route wisely can also help conserve power. Avoiding routes with steep inclines and areas prone to heavy traffic can reduce the need for stop-and-go driving, which is less energy-efficient. Many EVs offer eco-routing options in their navigation systems, which can help in planning the most energy-efficient routes.

6. Regular Maintenance

Ensuring your EV receives regular maintenance is vital for optimal performance. A well-maintained vehicle, with all its systems, including the battery and electric motor, in top condition, operates more effectively, which can help reduce how much electricity a green car uses.

Top-Up Charging: Strategy and Benefits

Keeping to the above best practices will indeed help you get the most out of each kWh. However, there is one other highly effective strategy that is a game-changer for electric vehicle owners: top-up charging. 

Top-up charging isn't about waiting for your battery to flash warning signals of depletion before plugging in. By charging your EV during shorter, more frequent intervals – say, while shopping at the supermarket, parked at the office, or even during a quick stop at home – you maintain a higher average battery level. This approach not only sidesteps the need for prolonged powering sessions but also keeps you ready for impromptu journeys, ensuring that range anxiety becomes a thing of the past.

Moreover, top-up charging can also lead to financial savings. Utilising public points during off-peak hours or taking advantage of free powering facilities offered by some businesses and shopping centres can reduce the cost. In addition to this, maintaining your battery at moderate charge levels can help prolong its overall lifespan, safeguarding your investment in the long run.
