Current Diesel Prices = £6.59 per gallon
Current Petrol Prices = £6.50 per gallon
So that's £6.50 (rounded for ease) per whatever your MPG is. I'd say worst is around 30mpg, best is around 50mpg. SO lets take an average of 40mpg. £6.50 for 40 miles.
Most EVs will do between 3 to 4 miles per KWH.
So best case* is:-
- 70p - 84p= Home charging on night tariff
- £3.20 to £4.20 = Home charging on normal tariff
- £4.90 to £5.60 = Public Slow charging
- £7.50 to £9.75 = Rapid or Ultra Rapid
*based on current weighted average charges for 49p per kwh for slow and 75p per kwh for fast as at June 2023 supplied by ZapMap. Note that each company has variations. BP Pulse for example is only 44p per kwh if you are a member. If your home energy is supplied by Octopus on Intelligent Octopus you can use Octopus electroverse for an 8% discount on all partnered public charging points etc.
So other than rapid or ultra-rapid, every type of charging works out cheaper than Diesel or Petrol. Not only that but prices at the moment are historically high. Home charges have dropped significantly at the start of July. We would therefore expect a similar drop in public charging prices, which would bring
all charging back down to below the cost of petrol or diesel. Similarly in the last two years we have seen Petrol and Diesel prices up over £2 per litre, whereas now they have dropped back to around the £1.50 mark.
Remember that Rapid and Ultra-Rapid are
not meant for daily charging. They are for a fast top up and the vast majority of EV drivers use them very little. And with things like Electroverse a Shell rapid charger at 85p per kwh becomes 55p per kwh.
Thus it is fundamentally dishonest to claim that Petrol and Diesel are cheaper than EV charging. They aren't. This is the sort of journalism you get in the Daily Fail.
