When are you going fully electric?

Got a mate who's getting a cheap leaf as a second car.

In the same budget frame of mind he's asked instead of getting a 700 quid EV charger plus install, why not get a leccy to do the following:

40A RCD Breaker, 6mm Cable going to one of these

Then get a £150 32A portable charger from Amazon?

Yes, although is you are using it for EV charging, you still need to follow the same EV charge point regs for it to be compliant.

That means it needs PEN fault protection device or an earth rod. You also can’t use a cheap type A RCD/RCBO, you’d need the much more expensive type B for the DC leakage protection. All the (good) charge points on the market have this built in already.

Likewise you should really still notify the DNO if the intention is to use it for EV charging.

When you do this the costs suddenly add up and are much closer to the cost of a proper charge point.

You can of course not bother and no one is really any the wiser and it’s technically compliant without an EV charger being plugged into it.

The other thing to consider is if you can get the best tariff for your use case. Is the car compatible with Octopus Intelligent Go?

Eon drive next doesn’t need a smart charger or compatible car.

Those are probably the two best on the market right now.

AFAIK the only practical disadvantage of doing that versus a smart charger is that you need to rely on the car for any time of use tariffs.

Chap at work uses the same on his Tesla and runs Octopus IGo via the cars integration with varying levels of success :p

To be fair though, if you are going to the effort of getting that installed properly you might as well get the real deal and have a tethered charger installed.

The part that I missed is that in a domestic setting, the commando socket also needs to be interlocking because there are no gates over the live and neural conductors like there are on a 13A socket.

The interlocking mechanism basically stops it from being switched on without a cable in it.

I’m not sure if that one linked above is or not but they are not expensive to buy.
 
The big one always HOWEVER if the wife jumps out to get something quick from a shop I might try the red button if I remember.
Looking forward to the forthcoming "I tried activating the EPB on its own but left the car in drive, took my foot off the brake pedal with the car still in drive and the EPB released itself* and I crashed into the wall of the shop" post

*may not be technically accurate

V PEN cu £85
Pricing up the hardware for a home ev charger install (for id3)

myself and neighbours each have a 2.5mm2 cable over a distance of 25/30M to get to garages and it would cost £4/5K to dig up paving and install a 4+mm2 (probably can't pull a bigger cable through)
looks like existing cable could pull 3.7KW within the 5% voltage drop limits
if we then had a
PME FAULT DETECTION METAL CU WITH RCBO AND SURGE PROTECTION £85

16 Amp 230V 3 Pin Interlock Socket Switched 2P+E Single Phase Blue £30​

Tesla – Commando Charger For 1 Phase 16A Commando Socket £200

any thoughts on pope maths ?
probably need an electrician to install it (to check CU connections, also I guess you must ferrule cables, and run tests)
the garage 2.5 cable would go exclusively to the PME unit, and other electrical stuff could be plugged in the commando inside garage, when not used for the ev parked outside garage (cable under door).
would need to use a fair amount of electricity above the power of a granny charger, to offset the install cost; neighbour with id4 currently limits his garage granny to 2Kw to avoid heating.
Seems ID3 could work on octopus Intelligent without need for a smart charger.
