Second hand car breaks down and needs expensive part replaced! News at 10!
Over the years, the Model S has shown a battery degradation of less than 20% over 300,000 miles from Tesla owner reports on Plug-In America. If these numbers continued at a constant rate, a Tesla could reach 450,000 miles before reaching the 30% degradation that Tesla deems unacceptable under its Battery and Drive Unit Warranty (450,000 miles is 3x the warranty period for mileage; for more details, see the warranty section below).
And it might not actually have to cost that much:. clicky
Once they have all the gremlins worked out of the battery tech, electric cars should last longer than ICE cars, simply because they have way fewer moving parts in the drive train. Hundreds if not thousands of parts in an ICE (valves, cams, chains, pumps, shafts, etc…) tens in a BEV.Martin Y wrote: ↑Sat Dec 25, 2021 10:12 amThat's what I was thinking. It will always be possible to buy an expensive car cheaply because it's out of warranty and find that it soon needs a big ticket repair that's more than you paid for the car. That doesn't mean it's inevitable and it doesn't seem like electric cars are going to change that calculation much.
And less extreme operating conditions (no high pressure and less heat) and less onerous maintenance requirements.bjn wrote: ↑Sat Dec 25, 2021 12:12 pmOnce they have all the gremlins worked out of the battery tech, electric cars should last longer than ICE cars, simply because they have way fewer moving parts in the drive train.

Prime Minister Boris Johnson announced plans last month for a charging point to be required for every new or refurbished residential building from next year amid great fanfare, saying the regulations were “world-leading”.
However, the decision to drop the requirement for existing non-residential buildings means the UK could fall behind the EU, which is introducing a rule for existing buildings to install cable routes for chargers after 2025.
It does rather put into perspective the tiny benefit of having solar panels on a car's roof to charge its battery if this super-efficient concept could only extend its range by 25km with a PV roof in the time it takes to drive 1,000km.
Recharging 25km/day would more than do for me most of the year actually.Martin Y wrote: ↑Fri Jan 07, 2022 8:36 pmIt does rather put into perspective the tiny benefit of having solar panels on a car's roof to charge its battery if this super-efficient concept could only extend its range by 25km with a PV roof in the time it takes to drive 1,000km.
On the upside, it's good to see at least the hope that future cars will not all have to be potato-shaped SUVs only distinguishable by their badge.
Prototype rather than concept, the difference being that a prototype is a working car not just a model. Jack even claims in that video that they’re going to licence it for the road and do real world driving in it.jimbob wrote: ↑Fri Jan 07, 2022 6:24 pmhttps://www.youtube.com/watch?v=Pt_c3gaO32g
A surprisingly plausible concept car from Mercedes (EQXX)
1000km range on 100kWh battery.
The aim is for the PV roof to give an extra 25km.
Good point.

Prototype racing frequently delivers technology for road cars, and prototype cars like this do too.
It apparently will do nearly that - it's higher spec than the Porsche Taycan and that will add 120 miles in 10 mins. Of course there's bugger all infrastructure for that kind of charging speed at the moment...
From Mercedes themselves...
I assume you don't need to be actually driving for the panels to charge the car.The electric system that powers many of the ancillaries in the VISION EQXX draws additional energy from 117 solar cells on the roof. It was developed in collaboration with the Fraunhofer Institute for Solar Energy Systems ISE – Europe's largest solar energy research institute. The net result of reducing the energy drain on the high-voltage system is an increase in range. On a single day and under ideal conditions, this can add up to 25 km of range on long-distance journeys.
From the description, it uses the PV on the roof for 'ancillary' systems - so it only works to reduce the burden on the main batteries for (I assume) things like lights, radio, internet connectivity, sensors etc.
There was a prototype camper van that a Dutch university put together that could charge its batteries from solar panels on the roof. It drove from the Netherlands to the South of Spain on solar power.Gfamily wrote: ↑Sat Jan 08, 2022 6:39 pmFrom the description, it uses the PV on the roof for 'ancillary' systems - so it only works to reduce the burden on the main batteries for (I assume) things like lights, radio, internet connectivity, sensors etc.
So I'd say it only works while the car is in use.
It would be great if you knew that running out of power could be resolved by the simple matter of leaving it under the sun for a day or two to give you 10 or 20km range, but it doesn't seem that that's what it does. .
