Fuel (diesel, specifically) in the UK is getting towards $10/gallon, so not surprising really!

A lot of fast chargers are over $1 per kwh so unless you have access to home charging there isn't much room for savings.

At some stage I wonder if the UK will need to regulate the charger industry. The price gouging is wild in places. If we look at the energy content of petrol, a litre of gas contains about 9kwh of energy, or at average pump prices 1.58/9 = ~18 pence a kwh.

For sure, EVs are far more efficient at converting a kwh of energy into forward motion, but if we assume 35 mpg (9.25 miles/litre) for the gas car, we need about 970wh to travel 1 mile. A modern EV can manage a mile on ~260wh, almost a quarter of the gas requirement.

There are public charging networks in the UK averaging 92p/kwh - we know we need much less energy to move the more efficient EV, but even with this adjustment fuel cost per mile looks like:

petrol at UK average today: 17p/mi

Electric at very expensive public charger: ~24p/mi !!

At many chargers, there are no savings at all. For comparisons sake, that 92p kwh would be just 28.6p on the most expensive domestic electricity supply, and charging at home would be ~8p per mile on the worst possible tariffs.

I've probably done some bad math somewhere here, but I think the broad picture is correct.

The biggest seller of EVs here is the salary sacrifice schemes that give a huge discount to high earners, especially those with kids. Imagine you're on taxable income of £120k and have two chidlren in nursery. Currently you get no help with childcare costs from the government. From my own experience it's ~£6000 subsidy per child. You can currently take out an EV salary sacrifice scheme for ~£600 per month (pre tax),…

But how long until those children are no longer in nursery and you are not subsedised for it? In ~2 years you will no longer have this help, you will be paying through the nose for the outstanding amount on your new car, and your take home will be significantly less each month.

Yeah, but you're still taxed at 72% between £100 and £125k if you have a student loan (as most people in that age bracket will be), so even in that case the hit to your take home isn't that much.

Electric price in the uk on an off peak tariff overnight is about 7p/kWh, or about 2p/mile, so charging your car overnight with the average electric mileage (10,000 miles a year - higher than the average mileage) costs £200, about £1300 a year less than petrol.

Can you actually get different tariffs in the UK for residential? In Canada most of that is pretty opaque. Electricity tariffs are not really something that most households would worry about. Businesses and Industrial usage do though

Sure

You can base it on the wholesale price, great if you have battery storage

Or just an overnight rate

Again if you put in a £5k 10kWh battery you are golden, as you put 8kWh into your car and 8kWh into your battery every night, dropping your electric cost to £38 a month (plus the standing charge, which is far higher)

Given that the majority of people in the uk have or can have access to home charging it's not a major problem https://www.racfoundation.org/research/mobility/still-standi... Wales – 75% of households have – or could have – off-street parking and EV charging England – 68% Scotland – 63% In London, sure, most homes don't have off-street parking and ev charging, but then only half the households in London have a car htt…

I think you're somewhat underselling the problem.

Even in Wales, 25% can't. This isn't a figure you can ignore.

And that's a hypothetical, it relies on landlords playing ball etc. then there's the social issues. On the north of England we have lots of terraces built for mill workers, these aren't owned by the richest on society. So then you're in the situation of charging the poorest more for transport. And these are necessarily on towns with good transport links (think 1 bus and hour).

Yeah, but you'll have a new car.

Obviously if you don't need a new car, it's a really bad financial decision to buy one.

And even if you do, it might be a bad financial decision to buy one.

Yes, the newer suppliers have EV and solar friendly domestic tariffs. Plug it in overnight, and the supplier determines when the charge happens and charges at the reduced rate.

Ignore the "EV" part. B = Battery H = Hybrid PH = Plug-in hybrid (Same as a hybrid but you can charge up the hybrid battery at home)

> PH = Plug-in hybrid (Same as a hybrid but you can charge up the hybrid battery at home) Surely that's the "same as a battery but you can use petrol on long journeys" The only energy input for a "hybrid" is from petrol. It's slightly more efficient. A Toyota Yaris 1.5 hubrid gets about 65mpg rather than the 45mpg on a Skoda Kamiq https://www.honestjohn.co.uk/realmpg/skoda/kamiq-2023 https://www.honestjohn.co.uk/real…

> Surely that's the "same as a battery but you can use petrol on long journeys"

No, that would be an EREV.

But compared to the US home charging via a mains outlet is much more viable because it's 240v vs 110v. If you plug you car overnight you'll typically have enough charge to last you the next day.

This isn't as big an advantage as you might think, as a huge number of US homes have 240v sockets to power the clothes dryer:

Almost everyone I know with an EV charging at home just reused the 240v dryer socket to avoid paying for a dedicated fast charger. It's often cheaper too to have an electrician fit a new 240v socket instead of the dedicated charger as well.
