Somewhat context free claim …
“The cost per mile running the average EV is less than half that of ICEs” is based on my (very approximate) calculations based on manufacturers web sites, and cost of electricity and petrol in France, which I used to make my decision which way to go when it was time to change my car.
My personal costs are more than one third of what they were when I ran a petrol hybrid but then I mostly use off peak electricity at home or free supermarket bornes when shopping.
I am guessing maintenance is going to be a lot less with no cooling systems, gear boxes, clutches, exhaust systems and engines with many moving parts whizzing around. I am aware of speculation about brake and tyre wear on EVs but am not witnessing it myself. (early days)
… and graph.
Is the graph supposed to be best case or average? What data did it use? When was it drawn (so we can see what might have been based on data and what was forecast). The start of the graph from 2010 to 2016 seems suspiciously straight, as though there were only points for those two years.
I simply asked Gemini to produce that graph based on World averages. Whatever people think of AI it is a useful tool. Of course the figures are not exact but they show a general trend that seems to be verified on most sites I visit. I would like to see an argument that batteries are not getting cheaper, giving longer range and using less environmentally unfriendly processes.
My personal experience of driving an average sized EV is that I get a range of 340 miles depending on my “guessometer” which swings a bit depending on how well I am driving.
If it’s supposed to be best case then it’s probably already out of date with the likes of the Mercedes EQS having a 118kWh battery and range of 500 miles (there are a few others on the market which have > 400 mile ranges, though they are all commensurately expensive).
What country?
France
Is depreciation factored in (the biggest cost for most motorists),
Well I PXd a 12 year old hybrid, which I originally bought for €17,000, for €10,000 despite sceptics at the time of purchase predicting it would need batteries replacing after 7 years. I doubt things will be much different for a full EV.
what about maintenance (cheaper than ICE)
Maintenance has to be much cheaper as mentioned in my answer above above. I have a friend with a Merc, just out of warranty, who spent a fortune on some fancy emissions control thing that went wrong and then on a fan system that had to be replaced. An EV simply does not have these items to go wrong.
and insurance (more expensive)?
I transferred my insurance from my old hybrid to a new EV and it is costing me an extra €5 per month. I guess an new ICE car would see a similar increase.
