What factors affect an EV charging time?
One of the main factors that impacts electric vehicle charging time is the type of charger you’re using. For example, are you charging using a plug at your home or are you using a dedicated fast public charger?
These chargers are given a kilowatt (kW) rating which lets you know how fast they charge. The higher the rating, the faster the charge. The size and efficiency of the battery also affects how long electric vehicles take to charge.
How long does it take to charge an EV?
Choose a make and model from the list, or if you already know it, you can enter the battery size and range.
How does the size of the battery affect electric vehicle charging time?
Simply put, the larger the battery the longer it will take to charge. How long depends on the output of the charger. For example, a Nissan Leaf with a 40kWh battery will take 11 hours to charge on a 3.7kW charger, whilst a Tesla Model S with a 75kWh battery will take 21 hours.
To work out how long it will take to charge your electric car, you take the size of the battery and then divide it by the power output. So, a 100kWh battery being charged with a 10kW charger will take 10 hours to charge.
How to maximise your EV range
'Range anxiety’' for some drivers is still a barrier to going electric. But should this be a reason to fear driving an electric car or have things moved on? Watch our EV explainer video for tips and tricks to maximise your vehicles range.
What is a good EV charging speed?
There’s not really a single “good” EV charging time as this will depend on your needs and your EV’s capabilities. It’ll also depend on how much you’re prioritising speed versus cost, especially when using public chargers.
Public EV chargers are typically classified by their EV charging speeds - ‘fast’, ‘rapid’ and ‘ultra-rapid’. Home chargers typically fall in the lower 3kW-7kW bracket.
Fast public chargers are usually 7kW - 22kW.
Rapid public chargers range from 50kW 100kW.
Ultra-rapid charger range from 100kW - 350kW.
For home chargers, a 7kW charger is a good choice as it’s a big speed boost over a standard outlet (3kW) and will fully charge most EVs overnight. If you often take long trips then it’s worth using faster public chargers (22kW and above) during pit-stops on your journey.
Ultra-rapid chargers boast the fastest electric vehicle charging times, but in practice only the most luxury EV models can currently accept chargers with such high EV charging speeds and power. Rapid chargers work with a wide range of EVs so offer a good balance of speed and compatibility.
How fast is a 7kW charger?
A lot of home chargers have 7kW speeds, and while this is a hefty speed boost from the power you’d get from a standard power outlet, it’s not going to be as fast as public chargers.
The exact charging speed of any charger depends on the specific model of car and the size and efficiency of its battery. A 7kW charger will typically charge about 25-30 miles of range per hour. So an EV with a moderately sized battery can often be fully charged overnight, or even within a few hours for smaller battery packs.
How fast is a 22kW EV charger?
You’ll typically find 22kW chargers at public electric vehicle charging stations. They can offer significantly faster EV charging times than home chargers.
As above, the exact charging speed you can expect to achieve depends on your car and its battery, but usually a 22kW charger can give around 60-90 miles of range per hour of charging time. This means that with just an hour top up you can give your EV a substantial boost, perfect for longer journeys or if you don't have an EV charger at home.
How fast is a 350kW EV charger?
A 350kW EV charger is classified as an ultra-rapid charger, and it's currently among the fastest EV charging speeds available.
To put it into perspective, a compatible EV can gain around 150-200 miles of range in as little as a 20 minute charge. However, not all EVs can handle such a high power output, so check your EV’s specifications before using a 350kW charger.
How fast are public charging points?
Public charging points range in charging speeds from around 7kW all the way up to the latest 350kW models. So depending on your battery size and efficiency you can expect a big range of charging speeds.
A 7kW fast charger will typically give a charge of about 25-30 miles of range per hour of charging. A 22kW fast charger will give you around 60-90 miles of range per hour of charging time. Rapid chargers are usually around 50kW, but can be up to 100kW. This means that you can charge most electric vehicles from empty to 80% in under an hour. An ultra-rapid 100kW charger can typically add around 30-60 miles of range in 10 minutes, depending on battery factors.
You can find ultra-rapid charging points across the UK, in a wide range of locations, from motorway service stations to public car parks, supermarket, gym or restaurant car parks. Some cars, for example plug-in hybrid cars don’t support ultra-rapid chargers, so it’s best to check whether your electric car can.
We’ve put together a handy guide on how to use EV charging points for you.
How much does it cost to charge at public charging stations?
Some public charging networks are free, however the majority will charge you (no pun intended).
Free public charging points are often located in supermarkets, public car parks and services stations. They may have restrictions covering their use, including limits on charging time, or requiring an-in store purchase, so it’s best to check before you charge.
For paid public charging points you can sign up to pay as you go or subscription services for electric vehicle charging networks, which will show you how much it will cost to charge as well as the locations of chargers that you can use with that service. Here’s our rundown of some of the biggest EV charging station networks in the UK.
Maximise your charge while you park.
More and more businesses are partnering up with EV charger networks to offer electric vehicle charging on their premises, including supermarkets, gyms, restaurants and hotels.
So it’s always a good idea to check on the locations of public charging points near you to see if you can tick off two items on your to-do list - the weekly shop or a workout and a car charge at the same time.
EV myths vs EV reality - The charging nightmare.
Perhaps you're worried about how long it takes to charge an electric car at home? Or you don't know where to find a public charger? Well we're here to update your thinking.
How quick is it to charge your electric vehicle at home?
While you can of course charge your vehicle from a standard domestic socket, it’l take a long time. The quickest way to charge your vehicle at home is by having a dedicated EV charging point installed. These are also called wallboxes and can give your car around 10 - 30 miles of range per hour.
Wall chargers, like other chargers, do also come in a range of kW, which means they’ll charge your car differently depending on how high the power rating is. The 7.4kW chargers that we offer charge up to 30 miles of range per hour. So if your electric car is mid-sized you can do a full charge overnight.
For smaller cars you can do a full charge within just a few hours. With the E.ON home app you can even schedule your car to charge at certain times to take advantage of off-peak electricity prices.
How do I get a home charger installed?
We can help you find the right electric vehicle charger for your car, working out what you need and then installing it for you. We can also help you apply for grants which can give up to £350 towards the cost of installing an EV charger at home if you're a landlord.
