Charging car in garage?

I should be getting my car in a couple of weeks, in the meantime I need to get the electrics sorted. The garage is one of a group of garages with the infrastructure almost there (the box and plug is ready, but we need to get the electrics connected and registered). If I drive into the garage nose first, the plug will be at the end.

I was assuming I would drive the car in, plug it in, close the door and go... is this ok? I have to say that the electrical fire thread has worried me (I wasn’t sure whether to post on that thread or here).

What does everyone else do? The charging port has to be inside the garage. I’ve noticed some people leave the garage door open, but I don’t know the reasoning (I don't know them to feel I can just go and ask them).

Just put your "I'm a newbie" badge on and ask. Most people (though I've only known one Norwegian) are fine unless they are in a hurry.

That said I suspect the reasons will range from tin-foil hat logic to "Well, the cat's gone to sleep in there", so don't expect a lot :)

I charged in my garage with the granny lead for three months before the charger was fitted in the garage. If using the granny lead just check that the plug/socket is not overheating, although if this a new installation there shouldn’t be any concerns.

My garage is attached to the house and is therefore part of the equipotential bonding zone and no earthing rod is enquired. Sounds as though this is a block of garages separate from the house. I am not sure of the regs but if fitting a charging unit this my need an earth rod? No matter because if it is a professional installation they will have done the necessary work.

No need to worry about shutting the garage door; our garage is locked at night and charging is in the early hours of the morning on the cheap tariff.

This is what we have in the garage (see picture). As you can see, we need to get an electrician to actually connect the socket. I assume the lead that comes with the car goes straight into this blue socket (no other adaptations needed and the plug supplied will definitely fit ???)

The metal box is the back of what looks like a circuit breaker (that you get in your house and all the sockets in the garages are connected to this). It's access from the outside.

ps is there a thread anywhere or a place that I can ask stupid newbie questions on?

Thank you!

That appears to be a 'commando' socket - possibly 16A given the situation.

You can't plug the car directly into that - you'll need a portable EVSE which is a box of electrical gubbins with a lead out each end. One end goes in the car, the other into that plug. (They come in different versions with different plugs for the supply end, but the same-ish for the car.)

Definitely a Commando socket in which case you need a 13 amp socket to Commando plug adaptor which is easy to get and quite cheap (I carry one in case I need to charge the car at a golf club). You plug your “granny lead” into the adaptor then into your wall socket. The granny lead should be supplied with the car and is recognisable as it has a 13 amp plug one end, a plug for the car at the other and a box in between.

Sorry! Yes, in Norway (but English so was drawn to the English forum - I can read the Norwegian ones, but felt more 'at home' posting here). I’m only just realising how different the cars can be in different countries (I thought other than rhd/ lhd, the cars would be more or less the same).

Re the plugs/ sockets, even if it’s not the same, I know what you’re talking about so I know what sort of things I need to ask for. My Norwegian is ok, but I need to know what I need to ask them first, otherwise I’ll be clueless.

In Norway, with more EVs than you can shake a stick at, every local jobbing electrician will be capable of supplying and fitting an EVSE in that location inside an hour by removing the commando socket to use that power supply and screwing the box to the wall.

As to the initial question, you probably have an equal risk of being struck by lightning than experiencing a garage fire with a properly installed EVSE.

Well, as this forum is very much UK based any advice will be based on our own EV charge point regulations and available systems. It has already been mentioned that our own regs over earthing such points have been gradually tightened up over the last few years and may still differ from the current situation in Norway. Only a fully qualified sparky there, with EV experience, will be able to give accurate advice in your situation.

Similarly, your choice of EVSE system will depend on your own budget and need for 'smart' features. There will be numerous wall boxes that just offer a basic 'dumb' supply with no timing, app, or power supplier links to access overnight cheaper tariffs on electricity. Those usually only vary on budget grounds as they become increasingly aesthetically pleasing from a simple black box. They all do the same thing. But some are 'prettier'.

Here in the UK there are now a few much more sophisticated chargers, such as the Zappi, that can organise links to home solar supply as well as timed tariffs to maximise economic car charging. Some power suppliers offer their own in house boxes that speak to their own servers. Octopus has one such system. But, apart from alerting you to the availability of such systems, we cannot be aware of what is specifically available in Norway. A switched-on sparky ( pun intended ) should be able to discuss such systems from local knowledge. Much depends on your own requirements but from what we have seen so far I would suspect that any basic EVSE installed, using the existing power supply to that blue outlet, would be sufficient for your immediate needs. And as it will be inside the garage there is little need to spend a lot on a fancy box.

Your main choice will be between tethered or untethered. I always prefer a tethered unit as the constant faff of fighting with a loose cable soon becomes a pain - leading to it being left permanently plugged in anyway. Much more convenient to grab a tethered plug and stick it in the car. Which leaves the loose cable tidy in the car boot for any away charge situation.

Please let us know how this goes eventually.

Ah, the dangers of trying to give advice on on a forum such as this. Full marks to those who spotted the Norwegian flag and, yes, the Commando socket makes more sense now.

Still, rather than waste my comment I would just mention that many golf buggies use a commando socket so if you are ever staying at a golf club hotel overnight you may be able to “borrow” a socket and plug in your granny lead with the adapter I mentioned. Alternatively, you could park below your hotel room and hang your extension lead out of the window which is what I did (needs must!)

Sorry for the confusion!! I see so many flags that, while it’s an English forum, I came here due to international members.

I hope that you don’t feel that any of the comments have been wasted (I’ve read many old posts on this forum and they’re appreciated very much even if the information isn’t always relevant). This thread has helped me to work out the sort of things I needed to ask in a foreign language. In the meantime, I've been told that I only need a type 2 to type 2 cable and when the electrician comes out, I’m going to to ask about tethered and untethered options (and if this is needed/ viable).

Thank you

No problem here. It's just that we can't really comment on the regs in Norway over the installation of a home charger. Many countries have 3 phase electricity as standard as well that further complicates matters. As you say, you will need a type 2 to type 2 cable but whether you use that purely for charging at sites away from home, or also from your home charger, will depend on your view over tethered or socketed units. Experience has shown that most people find the convenience of a tethered plug, especially when used inside a garage, outweighs the cosmetic appearance of a unit without a cable draped over it. Even people who opt for a socketed unit eventually leave the type 2/type 2 cable permanently in the socket. And then have to buy a second cable for away use. Going tethered in the first place simply avoids this experimental phase.

Here in the UK the grant-aided scheme now insists on a moderately expensive 'smart' charger being used. When in most cases a 'dumb' unit is all that is needed. From the info gleaned in here I suspect that a basic dumb tethered type 2 plugged charger, in a metal case to help with your fire phobia, will be all that is required. Your sparky will remove the commando blue socket and wire in such a unit in no time. Usually a type 2/type 2 cable comes with the car so you will then be covered for all circumstances.

Just updating after the electrician came out yesterday (in case anyone stumbles upon this later). Caveat that I’m in Norway, not UK

1. The socket on the wall has nothing to do with EVs😶. Someone early picked up on that.

2. While the wiring infrastructure is there, I need to buy a wall charging box. Can be tethered or untethered, but he’s coming back with prices.

Thank you everyone. I have SO much to learn!

If you mean the blue commando socket then that is only partly correct. It probably wasn't put there for an EV of course but just to provide a decent power supply for any future piece of equipment. As regards power for an EV, here in the UK it's possible to buy a complete EVSE that simply plugs into such a commando power supply. Equipment like this that can be a very economical way to charge an EV safely when there is already a blue commando socket in place.


And the Ohme model can handle a full 7.6Kw to charge faster - but is more expensive.
