Buy an EV and watch the cost of washing your clothes soar

I'm not convinced on that, at least if you are a heavy user. We are an electric household, ev and heatpump. We can use 120 units in 24 hours if charging the car. Today the heatpump will be running a lot and the car was charged over night, no solar production and I'd need a massive battery to make a dent in my usage. For me at least the best course of action is to maximize the use of the 12c rate overnight.
 

Those rates where you get a free day over the weekend would be best. In theory. But practically. We can't do everything we need to do in a week in one 24 hour block.

Everyone has a different use case.
 
A narrow window also means if you you have a need to charge outside those hours you'll be paying a high rate. Whereas a day night, or 24 hour rates gives you more flexibility.
 

The links don't answer the question asked. Almost no one has 3 phase in a domestic home. You're mostly only going to get 3 phase in a commercial setting. Vast majority of EVs only have 7kw AC charger on the car. A minority have 11kw (often an expensive extra) and tiny % have 22Kw. They are all limited to the 7kw limit on the vast majority of domestic house chargers.

(my math's might be off so apologies) so then consider a 3 hour EV rate of electricity with a 77kw battery a 7kw/h. If you are charging from 20%-80% (60%=46kw) that mean you will need 3 nights to get that to 80%.

Guess it depends how much you use, (how far you travel) in a day or a week. Then choose a electricity plan accordingly.

Even fewer would justify the thousands it would cost to upgrade to a 3 phase supply. Unless someone very close to you already has one you're looking at ~€5k, if not, a lot more!
 
Energia have a 4 hour 7c EV window. The charger actually runs at 7.2 KW, so I get 28.8KWh in that window each night.
 
I think its good to have a discussion there's a lot of nuance to it all, and a lot if misinformation.

You can set the car/charger to only charge in your cheap window. So just plug it in every night and forget about it. As there are different plans with longer windows.
 
Pesky electric cars only 92-97% efficient.
Fossil cars of course are only about 35% efficient, with the vast majority of the energy in the fuel wasted as heat.
yes of course i am more referring to AC/DC losses when home charging though! Adds up when you have a 86KWH usable battery
 
There are losses down the cable when you public charge also. Not much but it's there if we are dotting the "i" etc.

Petrol and diesel are incredibly dense power sources. A little goes a long way. So an engine inefficiency has less impact when it comes to efficiency. Of course there's more to it than that.

Nice not having a driveway of fumes and a pre heated car and clear windscreen this morning.
