Another thing about electric cars

I read an article that suggested fast charging doesn't affect capacity by much. An example:

Suggests that in a very hot area, regular fast charging a battery after

50,000 miles, the fast charge battery will deteriorate by 27% vs slower charging at 23%.

If done occasionally I doubt you'll ever notice.

probably at greater cost than hiring a car if there's 2 or more of you

And not everyone in the country lives at the start point of that kind of journey nor the end point is the final destination.

The 220 miles journey that I regularly do by car can be done by public transport on two routes. One requires 4 different trains and gets me to 20 miles of my final destination. The other 5 different trains and gets me to 9 miles of my final destination.

when I was looking for an EV a couple of months ago, the dealer kindly pointed out that the advertised mileage is a lot higher than the 'real world' mileage. I assume that involves heater, light & wipers and, possibly, a passenger. It was nearly 25% less :-(

but how are you going to get a street full of cars to share out the chargers fairly if they have to share on a 1 day in 7 basis?

When the battery is new, used in summer without the need for heating and when driven at less than 50 mph :) 70 mph is serious boy racer territory in an electric car :)

not just this government, unfortunately

Possibly only if you never fast charge them?

On one youtube video I watched the owner of a electric car that had been used for daily commuting and occasional weekend trips stated that his instrumentation reported that the battery capacity was down by 20% in 5 years.

Much like the rust guarantees that were only valid if the car had been inspected by the dealer every year as part of a dealer service.

Isn't it a chemical thing, much like 'they say' 500 full cycles of a li-ion laptop etc takes it to 80% original capacity?

Charging stations are more dangerous that 5G masts! All that high power electrical energy causes incontinence and no-one wants one close to their house :)

Couldn't have been a ford OHC then. Famous for snapped camshafts.

I regard that as pretty good, given my experience of LIPO cells

I think the jury is still out on that one. There are many aging Nissan Leafs that have had a lot of fast charging yet showing excellent battery health.

Well as a doyen of fast charging we (aeromodellers) used to reckon about

40% capacity lost doing one hour charges over a year of maybe 1 a week.

Everybody I met had a set of 'last years batteries' that were well substandard.

There is fast charging and battery abuse. Did charging take 15 minutes or less, or was it an hour. Did you measure temperature, and stop the charge at 80%. Were these the same Lithium Ion technology as used in cars?

That comes from abuse. What was the discharge rate? Did you monitor temperature during discharge?

Who was it with the travel-rug? Take a lucozade bottle and you're sorted

buying VW parts from the Skoda spares department saves you £££s for an identical item
