Electric cars, does everyone really think they are amazing.

I read this article the other day:
https://jalopnik.com/watch-volunteer-firefighters-...
... regarding German firefighters tackling a Tesla that's on fire.
Eye-widening advice given to firefighters is that they shouldn't touch any part of a crashed Tesla, as ALL of it may be live. There is a cut off in the frunk, but in the event of a front-end crash the only cut off is in the rear door jambs, which must be accessed by cutting into the rear wing using a circular saw...
Additional advice is that firefighters should only approach a burning Tesla wearing full respiratory equipment due to noxious fumes given off by the burning battery.
I know Formula-E drivers are told to jump out of the car after crashing, rather than stepping, to avoid grounding themselves. Is similar advice given to the owners of electric cars? Is there any risk at all of being electrocuted in the event of a crash?
(Yes, I know petrol is flammable etc, etc...)

Indeed, we don't care about range over speed, it's a non issue.
We don't care it takes 40mins for an 80% charge that should get us another 100miles or so,
What we do care is about you spouting the same rubbish, that seems to matter to you and no one else, and you getting your facts wrong in the face of superior knowledge, experience, maths, and thinking.
You obviously have a problem with being wrong.
You can't win this as you have the unstoppable pace of progress against you.

1) Firefighters are required to don BA equipment to protect themselves from noxious fumes given off by anything burning, even an ICE fuelled car. Modern cars are full of plastic, which is the major emitter of harmful by products of combustion
2) In the event of a serious accident (one which triggers the airbags or any part of the SRS system) the HV system is automatically disconnected. In fact, as the battery isolating contractors are powered from the LV (12v) battery, when the pyro fuse on that battery is triggered the HV battery MUST be disconnected
3) Firefighters are told, very sensibly not to touch stuff after an accident. That applies to ICE vehicles too, where fluid or fuel leaks, let alone sharp bits of damaged metal and plastic can cause injury. And that before we get to the fact that a modern car is FULL OF EXPLOSIVE DEVICES. Airbags, belt pre-tensioners, deployable bonnets, you name it, all of them can go off unexpectidly after and accident and ruin your day.
4) The HV system is isolated from the chassis. To get a shock you would have to touch both ends of the battery and have both battery disconnect contactors fail to open. In the case of massive chassis damage, then yes, it would theoretically be possible to have one end of the cell chain touching the ground, and therefore get a shock from touching just the other end of the chain. However, remember that fire fighters wear insulating boots and gloves because they have to work in burning buildings full of electrics and water in zero vis. As an occupant, so far, the only crash that has caused significant damage to the battery pack of a Tesla was so massive that the occupants were all killed on impact. At that point, waiting while the car is proven to be safe is not an issue.

You clearly don't even understand the basics.
Seriously, just Google heat pump efficiency, or coefficient of performance.
SY has told you all that he is smarter than google & wikipedia and the sum of all knowledge on the www why cant you just accept that.Seriously, just Google heat pump efficiency, or coefficient of performance.
He who knows not, and knows not that he knows not is a fool

So you're saying that both Nissan and Renault completely wasted the no doubt eyewatering amount of money they invested in developing such systems specifically to give them more efficiency for use in an EV, and they should have just bunged in an electrical resistive heater like my mate's old A4 TDi has for cold winter morning starts?
No.
You are wrong.
Clearly a massive waste of money when you think about how many they have sold.No.
You are wrong.

You're very good at having a go at the non-beleibers without ever adding anything constructive yourself. Like so many on these threads.
The first few pages of this thread were full fo constructive discussion but when a certain person has peddled the same idiocy which has already been refuted in detail there seems little point in going over it again.Interestingly, one thing Simon/this thread has done is increase my belief that EVs are going to start to take over very soon simply because he's so determined to come up with every excuse as to why they wont and he hasn't come up with anything that isn't either blatantly obvious or factually incorrect.

Reasonable criticism of the business decision to go so far in on EV investment while the market is still in its relative infancy. Doesn't really relate to whether it's the best heating system for the application. I'm not convinced EV tuning will really happen. An EV's drivetrain has two fundamental limits to its power output - the motor's maximum power output and the battery's maximum current draw. I'd imagine manufacturers are pretty good at pairing the two so the limits are similar which would mean to extract significant power without risk of damaging the batteries by drawing too much current from them you'd probably be looking at replacing both the batteries and the motor.

Has anyone on Here or on PH modified an EV as yet (I don’t mean visual enhancements instead performance upgrades).
I’m assuming it is possible BUT is it far more expensive and a highly skilled task than say “k and N filter innit”
There is a tuning kit for the Twizzy..I’m assuming it is possible BUT is it far more expensive and a highly skilled task than say “k and N filter innit”

Let me know which reputable engineering or technology institution you would believe, and I'll dig out their take on the efficiency of heat pumps.
I have gathered my own first hand evidence of heat pumps.But I take your point and thank you for making it. I haven't even tried checkingh reputable engineering co's thoughts on heat pumps.

Some meat for you all to chew on...
All taken from the well respected SMMT website.
Total new car registrations in Sept - nearly 430,000.
Total pure EV sales - 2000 (down from last year).
Hybrid - 15,000.
You do the math, as some people like to say.
Isn't that down to a decline in new car sales generally. All taken from the well respected SMMT website.

Your claiming a year to date sales increase on pure EV's of 37% is bad when new ICE cars dropped by 3.9% All taken from the well respected SMMT website.

What sir have you been imbibing?
The only drop there is diesel hybrids, which should be taken out back and shot anyhow.
