So the 2000km cars that "you've seen" are just some garbled info from a Scottish bloke and his girlfriend. Great. Sorry BvL but it's just nonsense and you shouldn't be so gullible. It will never happen. As for the 25kW chargers they would blow the fuses on almost every house in Britain. You'd need expensive upgrading of your ring main and you'd need a special (and even more expensive) connection the the grid. And you'd still never get the rate of charge that you want because the grid isn't capable of consistent power rates like this. Transient loads or OK but not large numbers of high loads over long periods of time. Unless you have a special connection. And the reason why China can do some things much more quickly than we can is because they're run by a dictatorship. If you don't have to get the permission of the public to do unpopular things then it's much easier. It may take the baron ages, but it took me seconds finance.yahoo.com/news/byd-shows-off-hybrid-powertrain-125608793.htmlThis is a HYBRID car that achieves 2000 km on one tank of gas Oops We're talking about PURE electric cars JOG - not cars that use petrol/diesel. The point is that fossil fuels have a staggering energy density - which is why they can easily do 2000km on one tank. You'd only need a 20 gallon tank which is no problem. And the hybrid technology just makes the car less efficient - not more. Check the figures. |

What makes you think you are any more honest? Most "ordinary Brits" know SFA about electric cars. To do 2000km in an electric car you'd need roughly a 500kWh battery - which would weigh about 5 metric tons and take up a huge amount of space - requiring a trailer. It would also costa fortune. It's about energy density BvL. |

What I was getting at is the only car that comes back in a search for an 'electric' vehicle capable of that range isn't a pure EV but a hybrid. Having owned an EV I know the best I got was 340 watts a mile although the telematics tried to tell me other people in other countries were getting far more... I simply couldn't see it myself they had to be cheating to get some of those figures claimed - 30 watts a mile my arse they must be getting pushed ... |

I don't know the details of these cars, except there was a picture of them and they were pretty aerodynamic. Batteries are being made smaller, lighter and more powerful these days. I have no idea how they do it, but these were ultra modern and just coming out. Yes it did sound a lot. I guess they must have made some technical progress. That was my point, and you don't know everything China has in its latest models and labs. Western reporters are rarely reporting the goings on in China where this couple live there.

Mining lithium to build mobile fire bombs is highly energy intensive. Building fuel cells is far less energy intensive and despite the flammable nature of hydrogen, is far safer than a lithium ion battery undergoing thermal runaway.

Building fuel cells is far less energy intensive and despite the flammable nature of hydrogen, is far safer than a lithium ion battery undergoing thermal runaway. Batteries catch on fire due to dendrite formation in the cells. See my video in the British Tech thread since someone is researching the application of graphene to halt dendrite growth.
So there you go, the Brits to the rescue!

They can catch fire due to internal short circuits.
They can swell and develop faults.
They are the wrong tech for cars which is why despite over 100 years of trying, nobody has ever been able to displace cars with fuel tanks.
The fuel cell will replace battery electric vehicles.
It's not only safer, refueling is faster than charging.
That means far more drivers can be accommodated per day per filling station than per charging station.

They can catch fire due to internal short circuits. . Correct, but its the dendrites that grow until they cause the short, and this then creates local heating and loss of performance. There is a lot of research into preventing this growth, e.g. the Japs had a different method, but I think it is safe to say we will eventually lick the problem. |

He said it was electric though!!!
I'll bear this in mind next time he mentions facts.

A sudden impact can cause a short. Roads often have stones which when kicked up can sometimes be enough to do damage.
There's loads of photos of electric car fires.

Sorry BvL but you just spouting utter nonsense. You seem to believe anything crap that comes from China - even if it's patently impossible.
And Vinny's right. Li-ion batteries are completely unsuited to cars - for so many reasons that I can't be bothered to go into it.

Li-ion batteries are completely unsuited to cars - for so many reasons that I can't be bothered to go into it. I know what happened there now. I believed a Brit, but the Brit did not know the fucking difference between an electric car and hybrid. What I have learnt, on the contrary from this, is to be even less trusting of a Brit, as especially the younger generation, of which this is an example.
Anyhow the mistake has nothing to do with China, even though I know you and Vinny want to believe that. The thing is I believe it is possible to get that range with some of the technologies in the lab right now. It was just a matter of whether any had come to market, but it is still premature.
This country and its people though are the fucking pits. I listen less and less to them these days because so much of what they say is full of error and that makes my information wrong. At least I admit to it though, unlike many on here who get shown proof.

No justification for the failed push for battery electric vehicles then.
Got it.
Fuel cells are better.

It was something like 100kWh but hardly cheap, as with all their cars. I don't think they do it anymore, but they do have electric ones. |

Prototype fuel cells aren't cheap, price comes down with mass production.
Think about it.
Another benefit of fuel cells, they're lighter than batteries, less flammable than lithium ion crap, cars have better range, cause less wear to the roads and have a longer service life costing less in maintenance.
