When are you going fully electric?

I don’t know where you’re getting your figures, but they don’t add up. You don’t pay 5p/kW 24/7. You pay 5p/kW for a 4 hour window and you pay at least 14p for the rest of the time. So your £3.75 figure is just not true. And I can’t be bothered to refute the rest of your post but it’s about as accurate as your £3.75 for a full charge at home claim. Sorry, but you’re MILES out.

Not sure how you can say "miles out" when I am basing this on real word experience for the last 9 months? Yes I pay 5p/kW for a 4 hour window, where my car automatically charges during that time. Every single kilowatt of electricity I've added to my car at home in the last 9 months has cost me 5 pence. I've posted the details of the efficiency of my home charger for anyone that is mega-interested.

You might choose to charge your car in a different way, for example on a less efficient 2.4kW granny-charger, or on a flat priced tariff because maybe you work away at night and can't use the cheaper overnight options, everyone's situation is different.

Everything I've said about supercharging are simple publicly available facts - there's nothing new or controversial there.

I’m tempted to drive to ASDA several times and charge for free just so I can say a full charge costs £0 and watch the fireworks of a QWERTY warrior.

How about Octopus Agile negative pricing where you earn £3 from charging your car and drying your laundry :D

Agile for me, which has been great as I am apparently a light electricity user, just waiting for the new solar and battery storage system to be given the go ahead and I'll be all set to get rid of my gas supply. Hopefully anyway, Covid really messed up the plans last year as it did for most people with a lot of things, first world problems. :(

He didn’t say in one go did he? I think I can see how your “go isn’t any cheaper” maths don’t work now from last time you brought the point up.

EDIT.
he’s even put the in caveat in his post of 40-80%!

Indeed thought I spelled it out with ..

Obviously a full charge from 0 isn’t possible in the 4hr window but would be my running costs as it would charge in that period. Say from 40-80%.

Maybe @WJA96 missed it.
My point is normal usage 4 hrs is more than sufficient for most each night and using that a full charge would work out around £4 for a M3P

Weird narrative again above that got decimated last time I look at the numbers when challenged on the “special tariff” - I don’t know what you have to be doing “working from home” for the simple maths to not pay off with Octopus tariffs.

I assume a baker or growing weed in the loft? :D

Ha, I was just thinking that - my mum has just got an Ioniq and I calculated that Octopus Go will save at least £130 a year versus the cheapest available single rate tariff, even assuming 95% of household usage is at the peak rate and only 90% of charging is done in the off peak window (it won't, it'll likely be 100%).
 
We're on Avro and it's a flat rate 12.6p. I'd have to sit and calculate it all but I imagine it would more or less average out against Octopus Go, since my OH works from home and the children running amok.

Don’t worry blun, I read your post in context. Don’t let the posts above frustrate you. :)

i can charge my car for only a little more aswell from home. As I don’t use a full battery every day like most people. If consumption did increase first change to do would shift to 5.5p Go Faster for 5 hours starting 8:30pm.

The Health & Safety lady came and measured the light levels and said we had to run the lights all day. I hadn’t really thought about it before but pretty much every office runs artificial light all day because there is a legal requirement for a minimum illumination level so you don’t destroy your eyesight.

Obviously we have low wattage LED bulbs but it’s still a lot of power.

And yes, you can fully charge your car for free. Lots of folks manage it.

You appear to live in a strange world where things are free and you only drive tiny distances. That might not be everyone. You understand that, surely? And your increasing agitated and aggressive posting just seems to suggest you’re not an entirely rational individual. And as you’ve admitted you’re trolling I’m going to ignore you.
 
Even if you use a lot of electricity during the day, Octopus Go still makes sense if you have an EV to charge overnight. I have a large house and there are multiple people at home during the day all the time.

The cheapest flat rate energy provider possible charges, in our area: 13.665p / kWh
Octopus Go charges 14.175p / kWh peak and 5p / kWh off peak

We've not driven much recently because of lockdown, but Octopus Go has made our average cost per unit this year 9.92p / kWh - a considerable saving compared to 13.665p / kWh.

The only things at home which really use large amounts of power are ovens and tumble dryers (and of course electric heating if you have it). LED lighting is so cheap it's almost insignificant (e.g a bright LED bulb that could light a large room costs about £0.0028 per hour (6.7 pence per 24 hours).

Octopus Go does only allow you to add around 120 miles of range per night due to the 4 hour window, although as mentioned above you get get their "Go Faster" tariff which gives you 5 hours / 150miles overnight (costs half a penny per kWh more). So if you're driving over 150 miles per day every day then you'll have to do a bit of charging at the more expensive rate.

I'm going to have to sit and work the costs then, since I still drive to work 40 miles round trip every day. I ought to look into a timer on the tumble dryer because that thing gets used, a lot.

As you noted, making the most of EV specific tariffs depends on mileage, so it isn’t a default choice for everyone.
For me, the low 4-5 hour overnight cost isn’t enough of a saving to offset the higher cost for the rest of the time, purely because I’m not recharging every night.

I’m currently on a flat 12.5p per kWh and 20p daily charge.
I might save a couple of pounds a month on an EV tariff if I scheduled our dishwasher and washing machine to start at 4:30am :p
 
Definitely still worth doing the maths - as even if you're doing 30 miles a week you would probably find your bills are lower on Octopus Go.

Scheduling appliances is worth doing if you can to take extra advantage of it (unfortunately my washer and dryer don't have timers - I'll make sure the next ones do!)

Would be interesting. I’ve had all of us at home, high computer use and kids on teams and Xbox etc around 17kWh... charging the car up has pushed day use up to 40kWh where my day rate is 13.4p... ie huge difference!

Hows that’s for rational? You are probably picking up the sarcastic tone cos I literally cannot comprehend firstly the counter argument, nor the lack of data. Suggesting i get good results from Go by doing tiny mile is very odd, the results come from pushing that average penny rate down by having high consumption.

Lightbulbs are largely irrelevant for a single room in a house! It a good point and why I have a desk light firing against the wall in my “office” even though it’s below a skylight - I still know charging a car for 5min will use more energy than that lamp in 24hrs.

PS. I also delay dishwasher to run at 1am :)

Good point! We could just leave it as electricity is cheap, and even cheaper overnight. So do some investigation, choose the right tariff and shift load to overnight where possible.

This is also good from an environment view if you care about that sorta thing :)

With a 38kWh battery on the Ioniq you’d not quite manage a full charge in 4 hours but you would on a 28kWh Ioniq.

But I’m sure the original query was about a Model 3 Performance.
