Adventures in an all electric vehicle.

Ha,ha,ha. These are LITHIUM ION batteries not NiCads. You are about a decade, or more, behind the times.

Any battery life can be shortened. Part-charging NiCads was a prime example. Overheating does no battery any good. Discharging automotive lead/ acid batteries and not replenishing that charge soon sulphates the plates; nor will discharging them to less than 50% state of charge - not even recommended on traction Pb batterries.

Litium ion cells are good because they do not get a ‘memory’. Full stop. However, they may develop dendrites if left for long periods at full charge and must not be completely discharged - all taken care of by the BMS.

However, the LIFePO4 batteries (that are only just being used in EVs) are actually recommended to be fully charged each week. liFePO4 batteries are inherently safer than the older chemistries because they do not easily catch on fire (cells can be impaled, with immunity, unlike older chemistries). The down-sides of these newer vehicle chemistry batteries is that of lower power density and reduced maximum discharge rate. But battery developments continue to improve. They are accepted as perfectly adequate for most EV models - most new Teslas now use that technology.

Please go back to school and try to come up with real reasons before showing yourself up with such claims.

Millions of Lithium ion batteries have been used in power tools - they superseded NiCads years ago.

Probably billions of mobile phones don’t get a ‘memory‘ problem - they usually fail due to high charge voltages for the cell (to maximise running time) and/or overheating.

If Lithium ion batteries suffered from a ‘memory’ problem like NiCads, most current EV batteries would be dead by now (like all those that have rarely, if ever, been charged above 80%.

All you can do is insult people. You must have a very sad life.

I have a Lithium Ion Laptop here that was left plugged in all the time. It was gifted to me, the battery is knackered, won't hold a charge for more than two hours.

And doing no harm, short rapid charging: Tell that to the Tesla owner I know, 2 1/2 years old and its range is now 60 miles.

If Toyota are serious about hydrogen they need to build a national network for refuelling their vehicles otherwise who will? They seem to be the only mainatream manufacturer taking this view on hydrogen so could potentially gain a huge competitive advantage being first to market.

I sort-of agree about the fast chargers, the only caveat is that L-ion batteries have thermal monitoring & charge management as part of the 'pack' so would request a charge rate reduction if the temperature was rising outside of acceptable limits. A lead-acid battery of the various types available rely on external calculations to control the charge rate and therefore internal temperature - clearly this only applies on-vehicle, some also have a temperature sensor built into the BMS to provide a rudimentary temperature monitor.
My NOCO L-ion battery booster pack has a fast charge capability, I've no intention of using it.

Yes, I aware of the tech in the L-ion batteries ref protection.
My point - was that they appear to be really pushing the limits, favouring short charge duration over the best procedure for battery life and battery long-term reliability.
Yes too on the Lead-Acid charging. You had battery temp sender which the charger used to adjust/compensate charging with battery temp change (as well as us being able to set parameters for staged voltage peaks, and Absorption Duration (also periodic Equalisation cycles etc).

That was a brave moment for them as a company. I wonder what his shareholders are thinking?

Tesla built an international supercharger network at the start and continue to improve it.

Nissan made their dealers install CHAdeMO rapids to recharge customer Leafs at the start.

Toyota's big cheese stated their reasons for not getting behind EV's, & their focus on Hydrogen as a more viable direction.
The commentary regarding a lot of the rest, was I think "fleshing-out" of the piece by whomever produced the video.

It's interesting that those (not just on this website, but wordwide) that had been pointing out the bleedin' obvious that the supply of batteries and electricity to charge them is not an infinite pool, were universally rounded upon as Luddites or Heretics going against the new religion of 'green' power ('power' in all it's senses) - now Toyota have put their head above the parapet, BEV interest & sales are declining (certainly from what I see in work), Renault are focussing on Hybrid tech and Tesla are shown to be peddling 'the Emperors new clothes', maybe 'we' can get back to reality and look at proper alternatives - hell, maybe we might even get back to being satisfied with just 'male' & 'female' genders?

Must be the reason why they catch fire. And lose their range over time.

But hey ho what do I know lol.


Compare it to pushing modern dervs for power and wondering why they go wrong a lot.

I don't think from the video that Toyota were looking to get into the Hydrogen Plant business - but who knows!
The message was though that they viewed Hydrogen as a more realistic avenue than EV.

I think (my take) is that Toyota see both Electric & Hydrogen as facing similar problems regarding the Energy Source (i.e. massive electricity resources for generation & distribution) FOR refuelling. There was the admitted problem that EV charging was getting much more support from Govts than Hydrogen Production (i.e. hardly any).
For either EV or Hydrogen cars as a mass transport solution, Toyota I think see Electrical Energy as the stumbling block - their choice to focus on hydrogen vehicles over EV seemed based far more that they were convinced that EV's were absolutely the wrong avenue & non-viable (as per earlier post)

They have to explore all avenues for fueling transport.

Bevs will be apart of it - city cars.

There is not enough lithium on the planet to fuel 75% of the road transport we have now - let alone fueling a growing world transport market.

--------

We will see - what I can say is - it will be a changing market place!

From what I can make out - Toyota the planets biggest vehicle manufacturer - are sticking to the concept of PHEVS (correct me if I am wrong).

Really there ARE only 2 actual Genders.
The rest are all "wishes" or "wants" - I can see & accept there are people who feel with every fibre of their being.... that they were born as the wrong gender in the wrong body - bit even that doesn't change the physical reality.
I identify as a multi-millionaire..... but that does not make me one.

I'm all for tolerance & acceptance of individual differences, but we should draw the line at fiction & fantasy. It is what it is & all that

@GRW - hold this thought mate!

I do wonder if the Taliban / AQ will be swapping out their diesel planet (and people) killing pickups for more sustainable transport - the thought of putting a LAW into a L-ion battery or hydrogen tank underneath some scrotes hosing down a village with a Dushka makes me smile.

Finally, I've found a positive in all this

Can't see a BEV "technical" with a 50cal on it working somehow mate...

I think people automatically assume that everyone has a mobile phone & is able to get assistance.
Then, there's the fact that people are more self-absorbed & uninterested in the problems of someone they font know.
Also, there is a much higher level of distrust & suspicion of other people (somewhat understandable).
Then, there is the risk that the person you intended to help - mistrusts or misinterprets your intentions & sees you as a threat.
Finally, there's the increasing possibility of being embroiled in some legal pickle, even sued - for being daft enough to try and assist a fellow human being.

So - it's no surprise that people just drive on by really.

The surprising thing I find that if you do "break the ice" most people will respond positively and if done lightheartedly will produce a smile and a good reply. It's all a question of your initial approach .

Fortunately in rural Wales where I womble about, there is still a good chance (away from the main arteries anyway) that a motorist /local farmer etc will stop & enquire if you're OK, and if you need assistance.
The bigger the road &/or conurbation though, the lower the chances are.

Please stop talking rubbish. That tesla owner‘s battery is faulty - it is still under warranty, I expect. I strongly suspect you are simply making things up, trying to justify your dislike (even hatred) of EVs.

Re the laptop - I expect the battery has a poor BMS, if at all, that has allowed over-charging and the battery has basically been cooked.

Maybe read the instructions? Many power tools (especially those with three-hour chargers) explicitly inform the owner/user to not over-charge the battery.

Happen lithium is just a stop gap electric battery form and will shortly be superceeded by an equal or greater capacity battery of water , ceramics and aluminium with microscopic holes in it . So long as you get the same dimension for change over batteries then no one will be much the wiser .

DShk has longer rounds than a 50cal - really old design of gun - your 1940's Russian Dushka

Good points well made. Sad but very true.

As a single male I'm very aware how things could be reported if I stop to be a good Samaritan for a lady stranded next to a broken down car, she panics and rings 999. There's also my safety - am I putting myself at risk?

Liability is another huge issue, you can't be accused of anything if you do nothing. If you stop and do anything the legal system can cause you all kinds of problems - do you really want to go to court after being accused of making things worse (either by touching an injured person or pushing a wrecked vehicle off the road to a place of safety?)

As said above, it's no surprise that people just drive past without stopping.

Great deal if assumptions there ndiy. A bullish delivery doesn't equal fact.

Weren't you just pontificating to me about the charging safety's & protections built-in to Lithium batteries & charging preventing user-misuse..... yet in this case - it suits you to accuse user-error?
