The all things EV chat thread

[PJ87]

One thing I have noticed @Mudball is efficiency seems to be very poor , it's the 100kw battery isnt it? So 19% used by the Mrs to go 28 miles is 19kwh used .. which efficiency wise is like 1.47 mpkwh which is awful

For reference my rubbish Corsa is 45kw battery summer is 170 miles (3.77 miles per kWh) winter 140 (3.1 miles per kWh

I'd be interested to know is the Mrs smashing the heating really high? Because anything under 2 is very bad

Unless she's doing 100mph ofc lol

I precondition every morning and leave the car on 21 degrees , heated seats on low and heated wheel on and managed the figures above. The wife however lol she smashes the heater up .. she seems to be of the mind set if she can't hear the blowers their not on

My wife does this, drives me mad. I leave the heating on 19.5°c all year round. It warms up the car in winter, clears the screens etc. My wife gets in, turns it up to full blast, then it gets too hot so she turns it down to freezing. 'Just leave it alone' .

On the efficiency point, there was a link posted recently, might have been @Mudball , showing a carwow test where they drove 4 electric cars until they ran out of power. They drove them normally, to replicate real life. Anyway, they kept talking about efficiency and I seem to remember they got 3.5-4.00 on the whole. This was largely motorway driving at 70. High end 3 something seemed to be the target.

no... the entry level model that i have has a total capacity of 76.6 kWh with a usable capacity is 71 kWh. So it feels forever thirsty.

The aircon on all our cars are magically set to about 22 Cel. It global warming inside my car. Never understand why it is like that. I can understand her turning it when she gets in.... but why leave it at that when the car has defrosted.

71 ah thanks, that makes more sense. 2kwh per mile. Not great but nowhere near as bad as 1.47

The weight won't help the car ofc but hopefully the efficiency picks up once everyone's used to the features

One thing to hammer home is heated wheel (if it has) and seats are much better for the range than air con when just one in the car . I don't mean don't use the heater at all just I keep mine at 21/22 all the time then the seats and wheel keep me warm without burning the range unnecessarily

My dentist had her air con in the room at 28 the other day. Jezz it was hot. Our air con at home we set to 22 and actually leave it for heating when used and it's roasting a much larger area

Think people worry about the number too much rather than how climate works

It's utterly ridiculous lol I mean I pre condition the car in summer and set it to 18 so it's nice and cool

I'll go in the car and boom 16 degree full blast on

Climate control is useless when the wife's around

my American mate has a 11Kw charger that uses a single phase. I have spent all afternoon trying to see if i get anything better than a 7k in a residential setup here . All answers seems to say, i can get 11 or 22 but I should have 3-phase power. basic estimate for 3-phase seems to be about 5K + new charger for 2k.. so easily looking at 7k additional.. there is no magic money tree

Do you need better? A 7kw will charge yours from 0-100 in 10 hours , can you see yourself needing it faster?

It has been scientificly shown that women feel 2-3 degrees colder than men.

So your 19.5 feels like 16.5 to her.

Mind you I have met a lot of men and women who do understand what a thermostat is.

American houses generally have a supply of 200amp (lower voltage of 110 V)

English houses have a supply of up to 100amp

The company installing your charger should have asked you what mains supply fuse you have to check what charger can be fitted.

A 7kw charger will use 28 amp roughly so that does not leave a lot of available power if you have a smaller than 100A supply.

EG cooking with oven and electric hobs on will take 45 amps or more depending on the wiring and fusing installed.

To check what supply you have just look at the rating of the main supply fuse.

See I've got 80 amp and I find I have plenty of room

I've ran (at the same time)

The car charger (32 amp)

The battery charging up (20 amp)

Dishwasher, washing machine, tumble (heat pump tho)

And run the air conditioning/ heat pump on that

All at once and I believe the most I pulled was 65 amp , but average was 60 amp

That said I have a combi boiler so not immersion heater to worry about

They did not... so i went around under the stairs and this is what i see... i cant see the rating on the fuse..
ps: the lose cables are not live... they are from the PV that has not been connected...

Now I know why she offered to pay childcare while I pay utilities;-)

Interesting how new build apartment is being fitted for EV... need more of these

It looks like your old meter tails are 16mm so you might only have 60A… get your sparky to have a quick look.

The fuse is where the red wire is coming out.

I agree with the comment from Fade and Die about the thickness of the red and black tails.

I was walking round an new build estate over Christmas. A lot of the houses had EV chargers that looked like that were put in when built and they were quite a few charges in the parking bays for the houses where they could not park next to the house.

tx @Fade and Die

The solar sparky is coming over on Friday so will check. Should i go for 100A?
If i have change from 60 to 100 is that something that the sparky does as a side hustle or do i need to go back to Octopus or UKPN?... At some point over the next 5 years, we may end up wth 2 EVs and chargers. i am happy to wait till then if needed/too expensive

 

[larmen]

Your electrician has to prep your side of the meter before ukpn does their side.

You need 25 mm tails, a 100 amp fuse board and a 100 amp meter. Once this is done they do change their tails to 25 m and the fuse to 100 amp as well.

It might already all be in place. Check if there is writing on your tails, for me they missed it and said tails are small. They were not and they had to come out twice.

I am 99% sure that doing anything to that fuse is restricted to UKPN.

@Mudball Clive is correct. Contact ukpn ask for an upgraded fuse

They came to me, said max I can have is 80 without unlooping, took 5 mins .. fuse out fuse in. Seal..done
