Fixing a problem with Tesla batteries

Quoted 20.000 euros for repair, guy chose the much cheaper solution...

With over 4m views the tesla owner prob made a few $$ from the adverts!

So in this case just 8 years economic life from a leading make of electric car, given the fact the petrol engined cars have been (or will be) pretty much taxed out of existence (so we have to buy one) I hope the current crop of electric cars last longer  only time will tell I guess.

Think about this: 60 to 80 kg of petrol \ diesel can easily, in some economic engine + good driving style, give one up towards 1000 to 1250 km, while 400 to 750 kg of batteries may only last around 400 km, much less for some models, and big loss in cold weather.

My trusty old van (Opel\Renault\Nissan etc Vivaro\Trafic etc) does 1350 km no problem with 90 L of diesel, any temperature. And got a 5 L can in case of crisis (never needed it). A mate's Tesla 85d does 350 km then panic & sweat takes over. And a big loss of km's in low temps or high speed. Next, helplessly stuck in a snowstorm waiting hours for towing lol. btw that Tesla 85 is fitted with close to 8000 (yes, eight thousand !) 18650 cells

An electric has to use much of it's energy constantly moving up to 600 kg of battery around (+ burns watts to cool the batts in summer, heat them in winter), a petrol car only has to transport like 30 to 40 kg average of fuel. Wondering how much range this "battery transport" activity eats up. Like constantly driving a petrol car with 5 people + filled up with heavy luggage? (...still the petrol car would maintain a decent range).

Price of battery swap aside, 1 thing is very, very wrong with the current generation of electric cars: storage of energy > disastrous battery weight (& volume) vs resulting driving range.

So, want to be rich very, very fast? "Simply" get the patent for a battery generation with 1\5th weight \ 5x energy \ 1\5th charge time \ 5x lifespan vs lithiums . Also, maybe we'll live to see hydrogen evolving towards real usefulness. Maybe a new hybrid: normal battery based propulsion (for daily routine) and an onboard hydrogen fueled charger (capable of doubling or tripling range when needed).

Personally, may get a cheap & minimalistic 'shopping cart' electric for town use \ shopping \ visiting folks nearby. As a main vehicle, electric is 111% out of the question until they fix that ridiculous battery weight \ range ratio.

Hydrogen power is badly needed

Elon Musk is a snake oil salesman that would put P T Barnem to shame.
He captured the press by building a car that was faster than a Farrari, cost twice as much and wil be worthless in 10 to 20 years
He then raced around the world giving away Tesla batteries to places ( like Australia ) who did not need them so again putting Tesla in the back of peoples minds so now th Tesla Power Wall is the larget selling household battery in the world , for people who want to play Russian roulette with thei home & the life of their family .
Then he signs a deal with China to make a "consummer" electric car and when sales of it take off he sells down his share holdings to "make his followers happy ".
Had nothing to do with grabbing the money & running before the poo meets the fan as the early generation of Teslas reach the enfd of their battery life & masses of them on the roads start having collisions & BBQing their occupants .
Lithium is about the worst power source for a motor car or truck
A scooter is about the limit of it's natural advantage over other systems.

Their is ZERO environmental advantge in driving an electric car, even if you power it with solar electricity, it will still take 8 to 10 years before the embedded pollution from an EV breaks even with the embedded polution + running pollution of a standard IC powered vehicle .
IT was a con from day one & remains a con.
Nothing wrong inherently with EV's if they provide a cheaper more convienent mode of transport, but reducing pollution is not a reason to buy one.

As for moron with the dynamite he should have been sitting inside the car when it went off
Wanton destruction of something that had generated so much pollution in its manufacture is strait out criminal .

Electric Vehicles are a con job. Still need coal fired power plants to charge them. Realistically they increase emissions not reduce them. I worked in automation and control which translates to power management tech for around 18 years so most of what they say reduces power consumption is BS.

but but..., a very satisfying explosion, no? Us small boys love such things !

This graph explodes a few myths, for the particular pair of volvo cars anyway, but to me the overall reduction in carbon emissions from using electric cars is not shown to be really that great, unless the electricity comes from green sources, which it won’t do in many countries.

[BSA_54A10]

About as much truth in those charts as in VW's diesel emmission data
If you trippled the CO2 from the battery production & doubled the emissions from the "end of use " then you are getting closer to reality
Those sorts of figures are for making the battery in a factory, & ignore the mining & refining.
Then there is other pollution involved in the mining & chemical conversion of the lithium.

We have one lithium miner down here that is attempting to make "green lithium " and they predicted it would neary double their production costs.
Then there is the big elephant in the room, namely shipping and the hundreds of millions of tons of bunker oil ( the dirtiest IC fuel, on the planet ) that is used to ship the lithium around the world 3 times as it goes from Australia or Chilie to China to the final assembly plant then trucked or shipped to the Volvo factory .

Replacing all of the IC cars alone with EV's will double the electricity consumption and the entire grid world wide will need to reworked .

It is lie a lot of things that appear to be a good idea in small numbers then become a disaster when scaled up
The planet does not have enough copper or cobalt to replace all of the current IC cars & motorcycles with EV's and that is assuming that 100 of the obsolete copper is recycled .
Those predictions come from some of the mining & metallurgy journals  subscride to.
Right now they are reopening Mt Lyle down here because the price of copper is now so high that what was passed over as being uneconomic to recover is now profitable
Copper uses almost as much electricity to produe as aluminium does if it is electro refinned and because we want power grade coppr ( 99,99% pure ) then most will be electro refinned .
Around 1/3 of the steel used in a "normal " car is recycled and about 10% of the copper  and the same for aluminium castings , don't know about the zinc .

In order to meet all of the "zero CO2" pledges the the use of wood , gas or coal for domestic heating & cooking will have to end & all be converted to electric appliances and that alone will neary double electricity demand from the developed world, let alone developing countries .
Havent seen the figures for a long while but something like 80% of all houses in the UK were heated with a gas furnace .
Convert them all to electric furnaces ( to keep the conversion costs down ) will add or e demand to the grid than it can currently supply and that will be 24/7 in a lot of places.
Even worse would be conversion to airconditioning leaking ozone depleting refrigerants and of course giving every one a headache from the constant rumbleing of the compressors .

Lots of BS being spread very thickly without much thought about what will sprout from it .
And as I hae mentioned before CO2 is only a small part of the problem that for some reason every one has become fixated with .
