EV general discussion

I’d work on the basis of about 3.5 miles per kWh. So divide your average mileage by 3.5 and that’s roughly how much energy you will use.

Yes that will not factor in public charging but the vast majority will be charging from home. Likewise it doesn’t factor in any day time charging or pre heating.

So 10,000 miles is around 3000kwh or just under doubling your typical households energy use.

That’s why EV tariffs make sense. Plus the October cap is more than the current day rate on Octopus go, so if your not on it and you have an EV, you should really get on it now as it’s fixed for a year.

Intelligent Octopus is 7.5p/kW from 11.30pm to 5.30am.

We're signing up now but having trouble with the charging check (the tariff is in beta), but as per now (Octopus Go), we'll charge our car, electric moped, and do washing/drying overnight with a timer to turn the plug off so the dryer doesn't stay on all the way through.

Do you need to have a proper car charger for this? 11:30-05:30 is ample to get me what I need over a 3pin plug but the website bins me off due to "incompatibility"?

Yes, specific cars or chargers only currently. They need to connect to either to turn the charging on or off remotely.
 
Gotcha. Thanks. That would have been a corker.

I imagine both my meter and charger were incompatible.

Is there an easy way to get a new meter?
 
If you have a Ohme you can use it on any car. Bear in mind intelligent is 6 hour period where it will try and charge the car when it can. It’s not guaranteed

What's wrong with your charger? I have a dumb charger. The car is more important.

I've only had a quick glance but the Octopus website just tells me either my car charger or meter is incompatible with their tariff. It doesn't mention the car AFAIK?

Either can work with octopus intelligent. I’d argue the compatible charger is better, cars tend to get changed more often.

Ask your supplier for a smart meter if you don’t have one.

You need both a smart meter and a compatible car or charger.

I have one, but it must be an older one. It is an economy 7 meter too (which seems odd as to why the meter would be different). Possibly a SMETS1?

I don't have a compatible car :)

I just mean for right now, 1 charger is compatible but something like 6 car brands are.

Ah I get you now.

In reality this needs to be an open standard that all smart chargers must support to be sold in the UK, its a shame the industry can't get organised or the regulator hasn't pulled their finger out to implement something. I'm sure someone somewhere is working on it but as always it will come too late and after millions of chargers have already been installed.

Yeah although as I said I've got a dumb charger because I always expected the app/backend to do any clever work. It's far easier to update an app than firmware (and far more importantly, force regular updates).
 
Thanks, not sure yet. Mine is fixed at around 18pkwh. So not sure what that would change to etc. Still on the fence might just end up getting a small run around for work commute. Like a polo/A1 or something. Will see.
 
Just bash some number in a spreadsheet to suit your assumptions and it'd be easy enough to work out what it cost to run, a new fix would be approx 40/7.5 at Octupus, after October who knows but it will likely be higher.

check fuel cost for 7.5p vs 18/40/55 etc. to see what it will set you back.

As an example my sheet for mpg cost for elec vs petrol/diesel is here, take a copy and adjust to suit you, this will no doubt open me up to scrutiny from the forum, just enter numbers in yellow boxes for vehicles your are considering, this was just to calculate commute costs hence only 11 months etc, so you might want to edit that, things I do personally can cost what they like, I am happy to burn up a number of tanks in a day for fun, the commute to work to me is nothing but a burden.

You can just tweak the numbers for days/wk and miles such that the Mileage for year comes out at what you would do, that would be sufficient.

Things like tyres and servicing costs are basically an average I have historically spent over a few years reduced to an approx cost per year.

This one drive link may or may not work.

To this add your electric usage for day multiplied by the different tariff amounts then you'll have ballpark numbers. for what you may or may not save.
