Re: Ever thought about a second hand Tesla?


Given Tesla are said to lose money on every car sold, it's no surprise their spares are expensive?

I see a few Teslas on my daily journey. Yes they are for people who want to make a statement somehow. Sure they must be nice to drive, and you would expect easy maintenance. But some complaints (youtube) about build quality of the body panels. A dent can be horrendously expensive to fix. I also wonder if you can live with battery degradation of about 10% per year. I'm driving a 23 year old petrol car which performs like new. Let me see... (0.9)^23 = 0.088629, or would be about 9% battery left :). So we're not quite there yet with the technology.

True, but Li-ion batteries deteriorate over long term usage. The internal resistance goes up with time, hence the batteries gets hotter and less current can safely be taken out.

Don't all batteries deteriorate with use?

If it's my 12V car battery, then I buy a new one in 5 years, cost £100. It it's a Tesla motor battery, costs???
There are liky to be many charge cycles, recomended load range is 20-80% to keep the battery health(ier).
My view is that curent Li-ion batteries are really not up to it. I hope that more durable types will come. E.g. solid with state electrolyte. There are also Li-air batteries being ivestigated; high energy density, high durability, but let down by low charge efficiency; this defeats the reason for using electricity inthe first place.But who knows, certainly, battery research is of major interest. Something will come along.

The Holy Grail being of course a suitable battery. Light small long lived and cheap. Perhaps one day. Everything else is easier.

Altough the a few now enjoy the credentials plus generous government grants, it's difficult to see how a wholesale change to EV is viable. Certaily the generouns handouts will be reversed. The charging infrastructure, the lithium raw material are other factors. What about lorries and busses, taxis which tend to run all day? And some countries are better suited if they have geothermal energy E.g. New Zealand. Various political cut off dates have been mentioned, it's entirely confusing: 2022, 2024, 2035, 2040. Seems that this may be intentional.

Many commercial vehicles like town buses and delivery trucks can run their working day on one tank of fuel. So you'd need a battery with that sort of capacity. There are very few vehicles that really do need refuelling quickly on a regular basis.
Best to ignore government predictions for cut off dates. They know no more than you or me. Frequently less. ;-)

Harrods in London had ancient electric vans up until not that long ago. And of course milk floats seemed to work OK. Most people could probably get away with an electric car for their daily commute, etc. Charged every night. But everyone seems to must have a range they only use once in a while.

Thing is, there's nothing more annoying than having a car that's only useful most of the time.

I could certainly use an electric car for my commute to work, it would almost be ideal. But what about getting to other work related events: Training, meetings, conferences; anything which underpin my job in the long run. The truth is that most people now with electric cars have a second car as well.

Even if I wanted one, living in a terraced house makes charging pretty much impossible. And I'd estimate (difficult to get a statistic but looks life over half) this applies to most UK households.
I'd mind less, but we've just had the pavements dug up and new LED street lights installed as part of a PFI scheme. An opportunity lost?

Our rural village is having a new main sewer installed. It would be so easy to install a duct for a fibre cable at the same time so we could all have "super-fast" internet insted of the 1 Mbits/sec that most of us get at present.
But there's no joined-up thinking about this sort of infrastructure!
And the sewer installation has necessitated digging a deep trench all along the road. It beats me why there isn't a tunnelling machine for this sort of work!

Why? Charging points are appearing round here. For charging cars parked in the street.
I'd guess there are far more cars parked overnight on the street than in driveways or garages.
