Most people drive cars that are more than 8 years old. :wink:
Yes and almost all of them only came with a 3 year warranty and they sill work just fine :P .

If you’re being glib for the sake of example implying EV’s are a bit dull to drive then I 100% agree. But then my Skoda superb was, and so was the Kia I had, oh and my wifes VW Golf, most cars are.

Many will have required new batteries to keep them working Just Fine. <£100 for most small ICE cars. Would be interested to know the cost of a new battery pack for a Nissan Leaf, for example? :P

I think the main difference is that not all engines need replaced after a certain amount of time or miles but you can guarantee that the batteries will need changed.

coldel wrote: Wed Dec 06, 2023 10:13 am From what I read the batteries on EVs, like any battery device take your mobile phone for example, degrade over time. Something like 2-3% a year by all accounts depending on use and brand etc. So after ten years yes your battery wont 'fail' but the range on your EV if it were 200 miles will now be around 140-160 miles for example.

I would definitely consider an EV for the boring driving, the about town driving picking up my son from football etc. the only problems I have are that I live in zone 3 London we have no driveway and often cannot park outside our own house - charging will be a complete hit and miss. There are charging bays in roads about 10 mins drive away but they are often full - I noticed EV cars often parked there for over 24 hours they use it as free parking which is annoying. To own an EV where I live I would have to take into account that I am going to have to drive past a petrol station and out to find charge points and sit there for however long waiting for it to charge.

Its ironic really that the best place to own an EV is more suburban areas, where driveways are more accessible but also less densely populated and probably not as prone to pollution issues. In the city where they are needed most, is the hardest place to own them unless you are very wealthy and lucky enough to own a big house.
You see this is a classic example of one of the myths about batteries that perpetuate on the Internet. The battery in your phone is completely unmanaged so does degrade by around 2-3% per year. In battery terms things like phones get abused, almost always being charged to 100% (ofter daily), almost always rapid charged, no thermal management system to stop them getting too hot or cold.

Not of these things are true with regards to EV batteries, with the exception of no thermal management on the early Nissan Leaf. EV batteries also have a built in buffer, our Skoda has an 82 kwh battery, only 77 kwh can be used. This stops the battery being stressed by being charged/depleted to its maximum.

Tesla batteries have been around the longest and their average drop off is 1-1.5% per year but then levels off to almost 0 when it gets to 90% of its original capacity. There are Tesla taxi's out there with 500,000 miles on the original battery.

I do agree that the infrastructure in urban areas is not good enough, but that's not an EV issue that's a government/local council not getting their s**t together issue. If they want us all to get on board then they need to provide infrastructure for people who can't charge at home.

Some councils are better than others. Quite a few are trialing a type of cable channel that will allow a cable to be run across a footpath if for example you live in a terraced house. I know I doesn't stop someone else parking in front of your house but it all helps.

Don't forget we've had around 140 years of refinement gone into building ICE car infrastructure, we've only had around 10 years for EV's.
The reference to the phone was more to show the example that batteries degrade, all of them do, rather than actually 'failing'. The rates at which depend on usage, the 2-3% was pulled from a test done on a number of cars that was done. I am sure in another test it probably is 1-1.5% but the point I was making being that they degrade rather than fail.

Interestingly the Tesla warranty on the battery is 100,000 miles 8-10 years AND no less than 70% battery retention (1500 recharge cycles as well I think). There is an acceptance even within Teslas own warranty that batteries if used a certain way can lose their capacity significantly, if that wasnt the case then that 70% would be much higher.

Actually the batteries (even though they will by the time they have done say 500k miles and be well down on their original capacity) will outlast the electric engines. I read about high mile Teslas 500k+ and the batteries are original but the motors are replaced multiple times.

Infrastructure is the problem for sure though. Councils have other priorities over and above charging electric cars, and their remit is very limited in any case, it should be the private sector building the infrastructure not council or government - sure there should be subsidies and grants but energy companies should be stepping in and taking that slot of building out large fast charging stations etc. There is quite simply no realistic solution right now for charging at home if you dont have a driveway, we cant sit and wait around for that to change.

I’d really love to know why you believe it will need a new battery? Genuine question. Where is the fact based evidence you have for this? Please god don’t tell me it was something you read in the Daily Fail!

I disagree, our entire economy and way of life is completely dependent on the easy movement of people and goods. Now the government has mandated that the way we do that Must change. For that to happen a fundamental part of the infrastructure that we need has to change too. To largely leave it to the free market to deal with is totally unacceptable , the government made the (massive) decision they need to be heavily involved in the solution.

Based on what evidence? If you have links to genuine evidence that EV batteries are “guaranteed” to need replacing the I would genuinely love to read it.

The infrastructure for moving is in place, the government have built a transit system for that purpose. The government have mandated that the fueling of vehicles must change, but the private sector provide the vehicles, they provide the fueling, they provide the maintenance of both, not the government. The private sector is already building infrastructure that we see on the roads in terms of charging stations, bays, and home solutions. The private sector build the actual EVs. This is where innovation and change comes from in response to government policy.

That said, the government will supply grants to the private sector to develop and innovate as they do with say the renewable energy sector as a response to the Paris agreement, billions of your tax pounds goes to energy companies to build wind farms and the like, but that is not the government building the energy infrastructure itself. EVs will be the same, they will aid with tax breaks and grants the private sector.

Can't say I read the papers. I use older model mobile phones though. Mobile Phone batteries are pretty hopeless after 8 years of regular charging. Time will tell for EV's

Not just electric car batteries but all batteries eventually need to be changed.
If they didn't we would never have to change the battery in our normal cars.

British Governments are very good at making decisions, but God awful at implementing them and creating solutions.

My local Council had the brilliant idea of putting in some EV charging points on a virtually unused piece of car park near our bus station. I would bet it cost the tax payer a lot more than it should have, as anything the Gov does seems to cost treble the going rate!
Due to where the idiot Council put these chargers ie the furthest parking area from the town centre, no-one uses them. Ever. Never seen a car at a charging point and I go past there almost daily.

The locals are still adjusting to mains electricity in their houses, so EVs are a good way off here yet! :D
All good things come to those who wait. I'm really impatient which explains a lot.

Tesla taxis? Every taxi driver I have spoken to whilst been driven in their hybrid has said you cannot do a taxi drivers shift in an electric car, it has to be hybrid and I have spoken to many taxi drivers.
