- If you're considering purchasing a second EV then you might be wondering if you will need two home EV charge points. In this video, our editor Danny explains why one charger will be fine for most people.
Despite the rapid growth in popularity for electric cars, they still represent less than 10% of new car sales (at the time of recording). So, they aren't quite mass market, but many EV drivers find the experience of driving an electric car so good that they get a second one.
This is why it's increasingly common to see multi-EV households already. Some of these drivers have asked us if they need two chargers to charge two electric cars. Our answer? No - in most cases you won't.
In this video, Danny explains why it's easy to share one charger but he also runs through some of your options if you still want more than one electric car charge point fitted.

Good vid as ever Danny. So I've got a 30kWh Soul EV and an 50kWh Peugeot e2008 and we manage fine with only a 3.6kW charger (electric feed to garage is only 20A - and we have a tumble dryer in there too!), doing 60 miles a day min between us (well when there isn't a lockdown!). Worth also pointing out that 2x 7.2kWh chargers would be 64A with is more than the usual incoming fuse on most houses @60A, so BANG! ;-)
Thanks Edwards and thanks for watching. Just goes to show you don't need superfast charging at home even with two EVs. To be honest, the main benefit for us of having faster home charging is so you can take advantage of cheaper electricity rates, but that's a video for another time.

Excellent video, really informative. Thanks.
Just got our 2nd EV this weekend. One thing of note is that our EV charger tracks history and Im trying to figure out if we can mark what car got what charge. A nice perk of having two would be the ability to track that easier.
If you are considering having 2 EV chargers, then you should get a qualified electrician to carry out an electrical load survey for you house and if you want to go ahead then before the installation make an "EV and HP Application" to your Distribution Network Operator (DNO) - in the East Midlands it is Western Power Distribution - who will make an assessment and sanction whether you can or can't proceed with the installation of 2 EV chargers.
The amount of power a household can draw at one time is limited by the capacity of the incoming mains supply cable, which in most homes would be fused at 60 , 80 or 100 Amps.
It depends on the mains voltage at the time, but a 7.2 kW load equates to about 32 Amps drawn.
So having 2 chargers at 32 Amps might not blow the main fuse if you have a 60A fuse, so long as absolutely nothing else in the house was switched on (unlikely). Hence the need to make sure that the EV chargers you are considering are actually capable of sharing the load between them (not all will do this).
The electrician can also confirm that all of the electrical cables leading to the EV chargers are adequate for the purpose. If the chargers are in a remote garage supplied from a consumer unit in the house, then the size of cable supplying the garage will have to be checked.
If it has a 4mm conductor, for instance, then that would be renewed.
Sounds like you know your stuff Robert. Essentially yes, there is a lot to consider if having two chargers installed. Fitting chargers with load balancing solves most of the issues, as you can set up max load depending on the main fuse capacity. In reality most people with an full EV only charge a few times a week, so a single charger can be rotated. Depends on how many miles the drivers do in a week but the UK average commute is only around 30km a day.
The WALLBOX has a design fault. The outlet is away from the Wall when it could be Flush, or almost. This would give an extra wind of the tethered cable around it making it a lot neater! There are two outlets on it. One blanked in my case. So could you charge 2 cars over night at the same time?
Another informative video, I’m amazed you have so few subscribers
Wow, thanks Chris. We're still quite a young TH-cam channel compared to our colleagues and our own website. Any likes and shares go a long way to changing that though, Chris 😉😉😉
There seem to be benefits in having two cars plugged in for battery and climate conditioning, which is a lifesaver if you have an early/icy start, so even if you load share it's worth considering a twin socket charger.
Great video as always 👍.
You mentioned in the video if you have single phase with two 7.2kwh charger, each charger will only give out 3.6kwh when used at the same time, does that mean if u had 3 charger the 7.2 would have to split 3 ways at 2.3kwh each? Is it not possible to obtain 7.2kwh from each charger? Is there a maximum number of 7.2 charger a single phase household can install? Thanks
Thanks Jason! I should say first that I am not an electrician and we have an experienced team who deal with this sort of thing and they help me with any videos that deal with more technical stuff.
For that reason, I try to avoid offering direct answers to technical questions in the comments as there are many variables to what can be achieved. Each installation needs to be assessed on numerous factors before finding the right solution. If you’re ready to get a charge point, the best thing is to start the process by requesting a quote from our website - then our in-house engineers will be able to assist.
Thanks for watching!

Funny..That 3 pin wall socket has gone the same way as mine with cracks on the faceplate from using the granny charger!
Ive got an walbox pulsar plus that you guys installed and at the time what caught my eye was that it could load balance with another. I prefer this other than having two chargers limited to 16amp since its dynamic in the way that neither charger will be limited permanently. Is this something that you guys have done with say two pulsar boxes?
I am intending to get another EV later in the year and possibly a small spare (can just plug that one in with 3 pin) but at some point there will most probably 5 EV's total in the house (me, mrs and both kids plus spare) and i dont this one charger will suffice plus I dont really think it will be good practice to have two cars charging on 3 pin, specially as they might be on the same ring. That plus there will be some redundancy.
Any advice on this?
Hello, thanks for watching. Wow, five EVs!
I can understand why you might want more than one charge point. My first thought is to check your supply can manage the extra demand.
I would recommend emailing our support team via support@smarthomecharge.co.uk
Mention your above details and they can pass them on to one of our technicians who should be able to access the photos from your original online survey to check the supply etc. Then we can go from there.
Thanks,

I have a Podpoint 7Kw charger and share it among 3 EVs, my old Nissan Leaf I charge every day due to its 85 mile range, my wife has an MG with 162 mile range and my son has an MG with a 200 mile range, both the latter don't need to charge every day and only do long journeys exceptionally. You mention charging from a standard 13A plug on occasions, before I got my Podpoint installed this 13A plug method used to blow my fusebox constantly! I'm not sure if this was a fault with the 13A adaptor or my fusebox......
Your fuse would trip for a few reason, you have the wrong MCB(fuse) in your fuse board for that socket ring main example all sockets should on b32Amp MCB covered by an RCD, if you have a lower MCB it would trip as the car is trying to pull to much power, second would be to many things plugged into that ring main example if you have the car your washing machine your oven tvs all connected to the same ring main it would trip the fuse as all the appliances are pulling more than MCB can provide.
Greater video, as usual! Some manufacturers recommend leaving car plugged in whenever at home though?
Thanks, glad you liked it! What's the issue with leaving it plugged in? Sorry - I'm not sure I understand.
Thanks for watching.

@@SmartHomeCharge HI. Tesla advise as follows: Model 3 has one of the most sophisticated battery
systems in the world. The most important way to
preserve the Battery is to LEAVE YOUR VEHICLE
PLUGGED IN when you are not using it........ When plugged in, Model 3 wakes up when needed to automatically maintain a charge level that maximizes the lifetime of the Battery. NOTE: When left idle and unplugged, your vehicle periodically uses energy from the Battery for system tests and recharging the 12V battery when necessary. There is no advantage to waiting until the Battery’s level is low before charging. In fact, the Battery
performs best when charged regularly.
I guess any of your solutions (dual socket charger or 13A plug) would take care of that.
They also advise using the mains supply to preheat the battery, clear the screen and warm the car before setting off of a long drive in order to maximise range (makes sense, and if left plugged in you don't need to gop out in the cold to do that...). Although, if setting off on a short drive with 80% charge I use the car's battery for all that as I've charged at a cheap rate overnight!
Leaving it plugged in also means I can charge the car more from the warmth of the kitchen if I realise I have a change of plans. 😊
Hope that makes sense. Keep up the good work!
Thank you, very useful video.
Although I did wonder if there was something wrong with my connection..you..talk..very...slowly!
Thanks for watching, though I can guarantee you if spoke faster I would get people saying the opposite of yourself.
There's a lot to get through and I try to make sure it is clear. Can't please everybody I'm afraid.
You could always find someone who speaks faster or watch it at 2
5x the speed! 😅
22kw charger equals 240 volts divided by 22,0000 watts equal 91.6 amps that a real draw on a 100 amp service. Average home draw around 33 amp at any time with out EV chargers.
22kwh requires 3 phase so that 3 x 100amp feeds to the home
@@damiendye6623 how many residential homes have 3 phase
Unless it a apartment complex
Most houses have single phase
A and B
And 3 phase most common in commercial 208 volts.
Black , Red, Blue.
And some commercials
Have 277 volts
Colors called ((BOY))
I forgot to say in upper comment it was 2 charging 1 Tesla and 1 Ford charger both draw 46amps they have 2 chargers at same time.
Now we’re upgrading to 200 to 400 amp service and rich people houses because there complain that 32 miles per hour is a slow charge now.
100 and 150 amp residential charging station are being put in now.
I have 50 old chargers I taken out of people houses they say just keep it .
So I charge to upgrade And keep the chargers I take out sitting in boxes in my garage on the shelf.
Not really old but old to them
@@davepetro5676 ok so by the voltage and charger current your clearly in the US
@@damiendye6623
Yes I am
Even higher voltage at the power planet
Then drop to
Then 12,800 volts on primary power lines
To different secondary off transformer.
Secondary
Star 5 cleanest voltage out there
Or
To dirty power
480 volts 3 phase
Or
240volts 3 - phase
277 volts 3 phase
208 volts 3 phase
Or
Single phase 120/ 240 volts.
That was nearly the shortest YT video ever.
Haha, I had to pad out a bit!

I have 3 ev's and they're all on 110v plug ins... help!!!
Ouch! Sounds tricky to manage! Well, your first step is to definitely get one dedicated home charge point. Even if you're sharing between three vehicles, it will be easier to manage than on slow charge points.

Very useful video as we've just bought or Soul EV - but can you speak more naturally please?
Thanks Lynda but that is my voice I'm afraid! I've been a writer for a long time but still pretty new to TH-cam and presenting so I'm sure I will get better with time... just trying my best to help people new to EVs, and that is more important to me than my presenting technique currently 😉 thanks for watching though and for the feedback.

The infrastructure around the UK is still rubbish.
The cost to the public for installing this equipment is disgusting, the average person can't afford all this, I do 45 miles each way and my wife does 39 miles each way, we both have hybrids and no intention of moving over to electric, plus the cost of electric vehicles are too expensive. It's all just a gimmick
