Getting my first EV here (booked, didn't confirm yet), they don't provide the charger but I don't mind to pay.

 

We live in a home with 2 phases and the small amp meter. The lady at the dealership said it's simple and we could request at PEA for a 3 phase, a bigger meter (30/100A) or a separate meter just for the car.

 

I found some meters on Homepro and they say in order to install it the home needs at least the 30/100A meter. Ok, sent wife off to PEA and they told her the only way to get approval for the 30/100A meter is to have the charger already installed, then the PEA technician will confirm that it actually needs a more capable meter.

 

But Homepro (for obvious reasons) refuses to install the charger unless the meter meets the specifications.

 

So it's a paradox. Can't install the charger without a 30/100A meter but can't get a 30/100A meter without a charger that demands it! How the hell am I supposed to get one then? Brown envelope?

Do you have 3 phase Supply in your Road available, and from where do you get your Wallbox?

Yes there is, but I heard and read that going from 2 phase to 3 phase would require major changes in the house electrical grid, which I want to avoid.

How small is your meter?
 

5/15 and you have a problem, 15/45 and you probably don’t.

 

No idea, the only label in the meter that suggests something says 5(100)A 

 

The meter model is EMS12J

You have a new digital meter. It's accurate between 5 and (100) amps.  Your car will charge at 32 amps.

 

What we don't know is what meter you had before, it was a 5/15 then the chances are the wires from the meter to the house are too small.

 

Are any of the wires at the meter blue by any chance?  Blue means 5/15 amp, not blue doesn't necessarily mean the opposite.

 

I would ask an electrician to come and ask him to fit an industrial 32 amp socket where you want your charger and on it's own dedicated 40 amp breaker.  If you don't have an ELCB breaker before your new socket, then fit one.

 

Then I would buy a portable EV Charger like the one below or a permanent one and ask them to fit a short tail and 32 amp plug on it.

 

That's great advice, thank you. The wires from the meter to the house are black I believe. Regardless, I'll do what you suggested and fit a dedicated beefy breaker/socket/wires straight out of the meter.

 

PEA should've just said "you've got a 100A meter, it's more than enough for a standard car charger, have a nice day" instead.

You could take a walk and find a meter with blue wires and compare the size of those blue wires to yours.

 

You do have enough power at the meter, the issue is whether your wiring to the house is big enough.  In Chiang Mai, our electrician took a second set of wires from the meter to a 40amp ELCB and then a 32 amp socket.  We have the standard wall mounted MG charger on the wall with a 32 amp plug fitted.  When we sell the house, the charger is not a permanent fixture and won't be sold with the house.

Best to have the installation inspected before diving in.


Down at our favourite noodle shop it's fun to watch the lights go dim and fans wind down when Miss Good Cat gives her EV a 7kW shot. Unfortunately the 100A digital meter and street cables don't agree.

 

ATTENTION! DO NOT SHOWER WHEN CAR IS CHARGING

Just a thought: If the cables to the house are not thick enough, you don't have to rip them out and install new ones but you can run new cables in parallel, so the 2 cables can carry the current. 

Ask your electrician.

Might be a bit messy if you run the 3 phase, but if it's a long run could save you money.

My plan is to install this charger very close to the meter itself, so the idea is to get a dedicated wire coming out of the meter that will feed this setup (ELCB->socket->charger). In this case it's not really relevant what sort of wire is going into the house, correct?

Correct.  As I mentioned, that's what we did at our house in Chiang Rai.

In that case why not get another off-peak meter (TOU think it's called) and use it for car charging only. Then you can charge during cheaper electricity rates.

Have to see PEA.

We have a 15/45A meter with blue incoming wires.

First 15/45 I have seen with blue wires, maybe your meter was replaced at some time?

Nope, new house so they came and installed the meter and the wires when our house was being built. And you can see from the pic that the blue wires are thicker than the black (which are 16 sq.mm. copper), so I am guessing that the blue wires are 25 sq.mm. aluminium.

 

Why would the colour be indicative of the wire thickness, anyway?

I don't know why the colour would be indicative, I can only say that around here, all the 5/15 single phase meters have blue wires and all the others tend to have black wires.

I would guess that at the time your local PEA ordered wires for their 5/15 meters, what was in stock was blue wire. Like-wise, when they ordered new wires for 15/45 meters, what was in stock at that time was black wires. Next time they run out and order new supplies, maybe it will be the other way around.

 

What I am trying to say is, that I don't think we should make any assumptions on wire size based on colour.

PEA is not providing a second Meter anymore since a while after they found that to many people using the Car Charging Meter for their House as well.

I thought that was the whole purpose of a TOU meter, that you would have cheaper electric during the night time, regardless of what is using electric.

At least that is how it is in civilized countries, where there is only 1 meter, which automatically switches to the lower tariff at a certain time.

TOU meters charge a higher than normal rate during the day.

 

The problem was people were using their normal meter during the day and their TOU meter at night.

That's a good way to fix the misuse of TOU meters (sledgehammer approach). Sherly they could cross-check the house meter bills and punish the poofteenth percent of naughty people.

Or using the same approach to fix the Bangkok traffic - ban the cars. 🙂
