How fast is a 22kW EV Charger?

How fast is a 22kW EV charger? A guide to 22kW EV charging

A 22kW home EV charger is considered a fast charger due to its high power output of 22 kilowatts, and is the fastest EV charger you can have installed at home (on a three-phase electricity supply).

However, there are key differences between AC 22kW home EV chargers and DC public 22kW chargers – meaning not all EVs can take advantage of the 22-kilowatt-an-hour charging rate at home.

If you’ve ever wondered about the speed and capabilities of a 22kW EV charger, keep reading to learn everything you need to know about 22kW charging as we answer how fast is a 22kW EV charger?

Can I get a 22kW EV charger at home?

Technically yes, you can get a 22kW EV charger at home – but you will need a three-phase electricity supply at home to take advantage of the 22kW power outlet. If a 22kW home charger is installed on a single-phase electricity supply, your electric car will only charge at 7kW, even if a 22kW charger is installed.

How long does a 22kW EV charger take to charge an electric car?

A 22kW EV charger is three times faster than a 7kW EV charger and six times faster than a 3-pin plug charger, adding 37-50 miles of range per hour. In turn, a 22kW charger can fully charge your electric car in approximately 3-4 hours and 1-2 hours to top up.

That said, the time it takes to charge an electric vehicle with a 22kW EV charger can be influenced by external factors, including battery capacity, weather conditions, and the state of charge of the EV battery when charging commences.

Are 22kW EV chargers AC or DC?

Both 22kW AC EV chargers and DC 22kW EV chargers exist. You’ll find AC 22kW EV chargers at home (although not as common as 7kW) or, more typically, at certain public charging locations. Meanwhile, 22kW DC EV chargers are usually only found in public spots, most notably at supermarkets, hotels and restaurants.

Any electric vehicle can use a 22kW DC EV charger, but unfortunately, not all electric vehicles can charge with a 22kW AC charger. Why? Because when it comes to discussing 22kW EV charging, it’s important to note that the charging speed of a 22kW EV charger is influenced by the vehicle’s onboard charger capabilities.

While most EVs on the UK market today with a maximum onboard charging rate of 7kW (or, more specifically, 7.2kW or 7.4kW), some, like the Tesla Model 3, have unique charging power at a rate of 11kW. However, a typical electric car will have a maximum AC charging rate of approximately 7kW, meaning you won’t charge any faster with a 22kW car charger.

Is 22kW fast charging?

Yes, 22kW EV charging is considered fast EV charging – as is charging your electric car with a 7kW charger.

In short, slow charging is charging at rates of 2kW/3kW and is found with three-pin plug EV chargers. On the other hand, rapid charging is typically for charging at rates of 43-50kW, and ultra-rapid charging (which is usually found at motorway services) can be at rates of upwards of 50kW, with some reaching heights of 350kW.

It’s important to consider that charging at high rates using rapid and ultra-rapid chargers consistently can damage your EV battery, which will result in a drop in your EV’s range. The best practice is to only use rapid chargers and ultra-rapid EV chargers when preparing for long journeys or in emergency situations and opt for a home EV charger to ensure a healthy battery instead.

Can I have a 22kW electric car charger at home?

Yes, you can have a 22kW EV charger fitted at home, but you will need a three-phase electricity supply to do so. Typically, three-phase electricity supplies are found in commercial buildings, but you can contact your local DNO if you are interested in upgrading your fuse.

You can’t have a single-phase 22kW EV charger, ever – a three-phase electricity supply is essential if you want to have a 22kW EV charger, whether for your home or business.

Easee 22kW EV charger

Can a 7kW electric car use a 22kW charger?

Technically yes, you can plug an EV with a 7kW onboard charger into a 22kW EV charger, and it will start charging – however, it will only charge at a rate of 7kW, not 22kW due to maximum onboard charging limits.

Can a Tesla charge at 22kW?

No, a Tesla can’t take full advantage of a 22kW AC EV charger as, typically, their maximum onboard charging rate is 11kW. In simple terms, this means even if you used a 22kW AC charger, your Tesla would only charge at a rate of 11kW.

Standard Installation
Our instant price is fixed if it falls within our standard installation package plus any additions that you have selected (extra cabling for example). This package covers the majority of homes in the UK. Before we undertake your installation we will carry out a digital survey to check that nothing has been missed. After reviewing the survey results some additional work may be required in order to complete your installation safely and to the required standards. If this is the case, we will contact you well before the installation date and advise the cost of any required work. You can then continue with your installation, or alternatively we will refund you in full if you do not want to proceed.

Included in our standard installation is :
• Fitting of a single phase charge point to a brick or plaster wall or other suitable permanent structure
• Up to 10 metres of cable, run and neatly clipped to the wall between the electricity supply meter / distribution board and the charge point.
• Routing of the cable through a drilled hole in a wall up to 500mm (20 inches) thick if this is needed.
• The fitting and testing of electrical connections and protections required for the charge point.
• An additional three way consumer unit, if required
• Installation of a Type A RCBO in an RCBO enclosure
• Up to 3 metres of plastic trunking to conceal interior wiring.
• An O-pen earth protection device if the charge point requires it. (This is NOT an earth rod)
• Up to 4 hours of labour from your installer to complete the work.
• Electrical testing of the whole installation.
• Handover and setup of the charge point and any app that may be needed.

Not included in our standard installation (additional work) :
• Where the installation requires additional cabling over and above the amount you have told us about.
• Upgrade/replacement of the main incoming supply fuse where the local DNO (eg Northern Powergrid) would need to attend site.
• If the charge point is to be mounted on a post/pedestal rather than an existing wall and where you have not selected a post as an extra cost option in your order.
• Installation of a charge point to a three phase supply.
• Where gas and water mains bonding (earthing) is not in place at your property. If this is not in place, additional work would be required before installation of the charge point.
• Any groundwork that has not been selected during the order process.

A Surge Protection Device is not included in our standard installation. 

What else you need to know :
• On the day of installation, please ensure that the area around your consumer unit (fuse box), incoming electricity supply meter and proposed charge point location (including where the cable is expected to be run) is clear and free of obstructions.
• We will need your WiFi password as part of the installation process in order to connect your charge point to the internet. Please have this available for the installer. Details will not be kept.
• The charge point must be on your own designated off road parking.
• The charger will be fixed in line with current guidelines at a height where it cannot be hit by a vehicle.
• Our installers are not able to enter loft spaces; lift floorboards or flooring; take apart any furniture of work above a height of 2m. If you anticipate that any of this may be required, then please contact us and we can discuss in more detail and provide you with a quotation.
• Should there be extreme weather conditions our installers may not be able to continue with you installation if it is not safe to do so (for example flooding). They will always do their best to complete the work where they can.
