Increasing costs of EV Charging

Do electric vehicles produce more tyre and brake pollution than their petrol and diesel equivalents?

https://www.rac.co.uk/drive/electric-cars/running/do-electric-vehicles-produce-more-tyre-and-brake-pollution-than-petrol-and/

From your own link, the answer is no:

"So, in conclusion, electric vehicles already vastly reduce particulate matter from brake wear, and claims of tyre wear contributing 1,000 times the particulate matter pollution of petrol and diesel exhausts are greatly overexaggerated. Real EV fleets are already seeing brake lifespans increased fourfold versus the diesel vehicles they have replaced, and tyre wear that is broadly on par with petrol and diesel cars (unless, as like with any vehicle, the drivers get a bit throttle happy!)."

Did you read it to the end?

According to this article it will take up to 10 years to cover the additional cost of an EV over an ICE purchase price when buying new

Looks like I'll have to wait a while longer to wonder how much EV charging will cost me ... just heard from the dealer that Volvo UK have cancelled my V60 PHEV order. 🙄

Yet the very same article says how on finance or lease agreements, the difference in monthly cost is small due to the increased residual.

This same higher residual value is true of purchasing outright, so trying to recoup the additional cost from the purchase price is irrelevant. Running costs and purchase costs are completely different types of cost.

The article assumes that everyone is paying 28p per kWh to charge at home. I'm paying 5p per kWh (when I'm not charging for free from solar or at the supermarket). I'm saving ~ £2k per year vs driving an ICE and will break even in comparison to keeping my old banger on the road after 10 years, assuming that my EV has zero value at that point and that it would have been possible to keep running a diesel car to 26 years old without it falling apart.

But you don't need to sit in the the car park. You can do some shopping, sit in the cafe, whatever. 

True, but for hours on end?  You would have to truly love those activities.

The best free charge you will get at a supermarket is 7kW (and some are less than half that), so in an hour the maximum charge is 7kWh.  As it only costs 5p per kWh to charge at home you only save 35p an hour absolute maximum.

You have to be a truly dedicated MSEer to do that just to get a reward of 35p/hour.

There are free 22 kW chargers in supermarket car parks. 

I have never seen a supermarket charger less than 7 kW. 


Also many people go shopping for hours on end...  (more than one shop perhaps?)

I just happened to be browsing the Audi website and looking at their EVs and there is an offer listed for 1 year subscription to a charging service plus £150 energy credit, which it states is equivalent to 1,000 free miles.  That works out to 15 pence per mile for public charging.

Audi also have another offer of £90 credit, equivalent to 4,500 miles of free electricity of you switch to their energy plan (Octopus).  That works out to 2 pence per mile for home charging.  I assume that is restricted off-peak hours so it may not be possible to get all charging at that rate.  The rate is lower than I'd expect the average to be for home charging.

Why? Most people home charging can top up comfortably in the 4 hour cheap window. That's about 28kwh or 84 miles of range - far above the UK average of about 15 miles/day.

You clearly have some generous supermarkets where you are if they are giving unlimited 22kW supplies.

Also, remember that few EV's are equipped with 22kW chargers anyway so unless you are saying that the shops provide free 22kW DC supplies they would not be able to exploit the generous offer.  If they do then please let us all know where they are.

Slot of the Tesco's with free chargers have both 7kW and 22kW chargers. All AC units.

You're right that most can't take more than 7kW, but for those with 11kW, or like myself with a Zoe, the 22kW charger is greatly appreciated!
