How powerful is a home EV charger?

Whether it’s a tiny home charger like an EO Mini Pro 2 or a larger ProjectEV home charger, the power of home chargers is broadly the same. Size makes no difference to power output.

There’s a good reason for this: The power of home chargers is limited by the power your home has available, not by their technical limits.

These easiest way to explain this is as follows.

100 AMP Fuse for an Electric Car Charger

Your home has a 100Amps of power in total. A fast home charger can use 32Amps of these but not more. If it used any more it would affect the use of your other home appliances.

What does this mean is real terms? In time to charge? Well, on average a fast home charger adds around 25 miles of range per hour to your car.

But why isn’t there more power in your home? Well, because when your home was built no-one envisaged people charging huge batteries up as well as using electric showers, electric cookers, electric heating, etc.

Some older or smaller homes have even less than 100Amps, typically 80 or 60. If your home has this amount of power there is some good news. A call to your electricity supplier can usually get you upgraded to 100Amps without charge.

Can you get more power? No, not really. You may see chargers with 11kW or 22kW charging capabilities, but these require commercial levels of electricity known as 3-phase. Fine if your charger is at the office but homes generally do not have 3-phase electricity and getting a supply of 3-phases power would be prohibitively expensive.

So, to summarise, all chargers charge at the same power levels. There are one or two exceptions for smaller properties or those with unusually large electricity requirements (heated swimming pool or ground source heat pumps for example), but in the main, home chargers are all 7kW/32Amps.

    really professional service from start to finish- total time from initial order to install was 7 days. Sunita communicated by phone and email and was really helpful in choice of charger and on the technical issues re install. Install by Marcello who was prompt, careful, considerate and really neat... in his installation. Overall really excellent and sets a high standard for other companies!read more

    Excellent end to end service. I spoke to quite a few companies to get a quote for my EV charger installation. Chargebase were the most professional and helpful. My installation was not a straightforward one because of the location of my meter. The electrician that came to install my EV charger did... an amazing job and exceeded my expectations.read more

    Sunita and the team, installed my EV charger earlier this year and gave an excellent service. Our house was hit by lightning which blew much of the electrics and Sunita has been very helpful in sourcing a replacement charger and electrician to assist.

    Very good service from initial inquiry through installation and commissioning. Installation itself was done within a few days and the connection itself is small and neat. Would definitely recommend using Chargebase for anyone looking for a home charging point.
