Charging EV at home?

So our Leaf has a 40kwh battery, depending on how you drive it does 3.5 - 4miles / kwh.
We regularly get 150miles on a charge, so thats 3.75miles/kwh
Lets say you sign up for Octopus and get it at 5p/kwh
So 40kwh x 5p = £2
So that's approx 150miles for £2

Don't think I could get anywhere near that with my nissan navara...
The Leaf (like many) has a charge schedule on it so it can start charging at whatever time you want.
It can also automatically defrost your windscreen ready for when you goto work/school run in the winter.
Thats nothing for fuel but do you cost the vehicle purchase price, interest, depreciation and repairs.
My old Nav has virtually stopped depreciating.

you have such costs on any vehicle.
SteveR asked what the costs might be to charge at home, I did my best to answer his question. Showing my working out.

Our situation was:
We got the Leaf 3 years ago, wife's car at the time was developing turbo problems (amongst other things).
So I quickly got rid of it, since it wasn't worth a great deal anyway so better let someone else fix it.
We export power to the grid almost 24/7 often for peanuts (depends on time of day/year etc)
So instead of putting £60 (approx) a week of diesel into her car, we can just use our own power.

For me it feels wrong to export all this power, then drive round to our diesel tanks and put diesel into vehicles.

Yes I could have bought her a £50 car and put diesel into that for less money, but I don't think that would have pleased her much.
Since getting the car, I often take it out over using my narava to save diesel money.

For those with solar, you can have an EV charger that monitors the export power levels and alters the car's charge rate to use that export.
This could work out a good price for those on the deemed 50% export.

Don't get me wrong EVs won't suit everyone.

And your final paras are exactly why I will be looking at an EV, as like you, we are on 50% deemed export, and although we use a lot of the juice in the DHW system, now there are only 2 of us here, too much is disappearing to the grid in the summer months. Winter time is very different! :)

I think I would look to dump more surplus into the EV, and then use the GS heat pump more for the DHW, as being better financially.

I even looked at an EV compact tractor recently, and was seriously considering it, but the cost was almost double the diesel, so the ICE stopped here a while longer...

Interesting,
Didn't know such things existed (yet)
I had heard that JCB have some hydrogen stuff coming.
But I digress.


The CET is available here... in theory. I do like the minimalist look of eFarmer though....


Or not quite here... apparently :rolleyes:

Ive set my charger to run from 1am to 5pm. That way it get solar energy during day then stops charging until night rate starts at 1 am.

In winter the stop time will be more like 3pm.
If its not sunny dont plug in until 5pm.

You can start/end a charger from phone app at any time.
Its possible to add a controller to charger to monitor solar export and charge accordingly.

An electric car does approx equivalent of 100 mpg energy wise
So 20p/kw would be like paying £7/gallon but getting 100mpg all the time. £1.55 per litre
Reduce your kw price using night rate and/or solar and figures are very nice.

A local fast charger is 35p/kw which is to be avoided at all costs.

No road tax on ev at present, but insurance is up by half the road tax saving.

My new car came with 0% finance which to be honest was the deal maker as much as the potential fuel savings.

Once the electric tractors get to 50 hp equivelent, plenty of applications in poly tunnels, produce stores, built up areas (council type work) & confined livestock building.

Be handy to plug electric tools into, do they have a three pin plug? Lighter than battery tools.

Love my Hydunai fork truck which replaced a 40 year old Lansing Bagnall. In busy warehouses in the past they used to swap batteries & work the fork trucks 24 hours a day. Less common now but still possible.

100kw to full charge still £20.
Go fair way on £20 petrol.

No, it's far cheaper. We've got a 30kW Leaf. It's good for 100 miles on a full charge. So the most you're looking at for a charge is £4.50. Though I pay less as I charge at night with cheap rate leccy and when we're charging during the day we're typically exporting from the panels so it's energy we'd have got 5.5p for.

If you can find an ICE vehicle that does 130 to the gallon you'll be paying less per mile. It wasn't an expensive car either, 2016, it's worth maybe £7500 now. We rented Leafs for 5 yrs and briefly went back to diesel. Paying £70 to fill the car up weekly gets old really quickly once you know how much better EVs are for local pottering about.

What’s your issue with the Polestar @Chris F? Quite like the look of it or its Volvo cousin?

Nothing in fairness. Really pleased with it at the price point. It is very Volvo like. Just a few more options in the hatchback range now. My only real need was to be able to put dogs in the boot. So Tesla model 3 was out. S and X way out of budget. As were the Merc's.

ID4, Nissan and Hyundai all in the market now, for delivery Oct time. Just makes it a more complicated decision.

The Kia Ioniq 5 is the one that's caught my eye, but I don't like spending money on new cars, it's an expensive hobby.

Back to running costs, we've covered 20k miles in nearly 2yrs, I reckon it's cost less than £500 in electricity. A car on petrol / diesel doing 40 to the gallon would have cost £3k in fuel. So, £2.5k saved. The car was £10k second hand, now worth £7.5k, there's no way you can crunch the numbers to make ICE look like it makes more sense for us.

Yes - that looks lovely too. I really can't pin depreciation on these cars. So little is know about how only they will last and running costs. But, if they do 500k miles then depreciation for first 10-15 years, will be quite slow. These are cars than could last 30 years. So buying new might not be a bad thing.

Its new tech that could make them halve in value.

Basically, that's why I leased for 4 years. Didn't fancy the risk.

Well, I did too. We had our first Leaf on a 3yr contract hire deal, the second on 2yrs. At that time they wanted ~£350+ per month rent for a new one (though cheaper deals have materialised since) , and I asked myself whether a 3yr old Leaf would lose more of less than £4000 per year in depreciation.

If I'd known how well Tesla Model 3s would cling on to their value I'd have bought one at launch. Sooner or later those prices have to start tumbling, but at the minute the residuals remain crazily high.
