Electric Vehicles (EV) Thread

[Ttmike]

Revenue from fuel tax in the uk last year was 28.4 billion pounds so the goverment have to make up that shortfall.
I would expect this is why new vehicles from 2022 must be fitted with electronic data recording.
And just maybe why they scrapped the tax disc, there has long been talk of charging motorists by the mile with increased charges in the large city's .
These new electronics will allow easy access to your driving data in electric or ic engines so I somehow doubt that electric cars will end up as a cheap alternative to petrol.

Thousands were paid to use extra renewable electricity on windy weekend
https://www.theguardian.com/business/20 ... dy-weekend

"Thousands of households were paid to use extra renewable electricity over the weekend as windfarms generated unprecedented levels of clean power.

Homes using a new type of smart-energy tariff were urged to plug in their electric vehicles overnight and set their dishwasher on a timer to take advantage of the record renewables in the early hours of the morning."

people will simply call a pod on their mobile and one will come to your house

I can't believe this fantasy is still being touted..!

Work it out - in cites around the world, traffic congestion is critical, yet here is an idea that would massively increase that congestion by clogging the roads with empty cars travelling between users.

If the technology is ever developed, it will be banned in short order..

[Ttmike]

I would disagree,
If you consider cars are parked up all day around london clogging the streets if as normal the car parks are full.
Banning technology would of course be stupid in the long term otherwise we would all still be driving model t Fords.
As I said there are already huge leaps in technology including lane control and anti collision and we so far have accepted these things.
As for empty cars I would assume they will be computer controlled to avoid long distances empty.
But I did read this,

Automation optimists envision a commuter utopia where urbanites whip around in shared, electric-powered, driver-less pods that travel close together in sync with self-driving taxis and minibuses, all connected to smart city infrastructure, potentially eliminating millions of private cars that are parked about 95 per cent of the time anyway.

Time will tell, and I hope I never see the end of the petrol engine.

Utter twaddle I travel and drive all over the country, I keep stuff in my car for convenience I tour some days taking photographs, people want cars for leisure and convenience. i also use it to get to work. My car is there when I want it. and

Many on here can remember being taken for a ride in their dads first car - my dads first car was a 1937 Morris 10 bought in about 1959. Compare that with a modern car today and then try to think of what will be available In just 30 years time from now - I’m sure there will be technology that we can’t even imagine.

I never wrote that it was simply a paste from one of many sites talking of future transport.
Now probably this will not affect you in your lifetime or mine but things change like it or not, the family car had all manner of uses shopping being just one.
But that is also changing as can be seen by the numbers of established shops and stores closing down.
People more and more seem to prefer to sit on their backsides and order from the internet, for me I think I lived in a golden age.
First car I had was a mk3 zodiac and have enjoyed driving all my life but things are changing fast.

[lindosfan1]

Ttnike Sorry , I agree it will not happen in my lifetime. If I was a lot younger I would not have children, the world my grand children are going to grow up in is not good.

Yes, the continuous evolution of technology, just like the their motors. It may just be a typo, but it completely negates the article when they write stuff like the following:

Traditionally, the building blocks of inverters are silicon power transistors called insulated-gate bipolar transistors (IGBTs), which switch the current up to around 20,000 times per second (20kHz).

followed by:

Equipmake’s inverter is based on a new type of silicon-carbide mosfet (metal-oxide-semiconductor field-effect transistor) that’s capable of switching charge at up to 80Hz.

I’m not sure where the anomaly is, where they are comparing the existing technology with their new technology?

The mis-quoted frequency. 80Hz is just over the mains frequency.(here 50Hz)

But in addition I believe that they are confusing the mosfet switching rate with the AC output that drives the motor.
It is not possible to drive an AC motor at 20Khz, never mind 80Khz! The motors are VFD(variable frequency drives) where the RPM is a function of the number of "poles" and the supply frequency. For such things as pump drives etc., the frequency range is usually between around 40Hz and 80Hz.

These vehicles are not practical in most of Canada, as even in Alberta, it is 300 kms
between Calgary to Edmonton. If I was to drive to Vancouver B.C. 900 kms I would
have to charge up to full twice, and find a charger in Vancouver on arrival. I would rather
use a gasoline or at best a hybrid vehicle like the Toyota Prius. The batteries on most
vehicles are not recyclable and especially on the hybrids and the electric vehicles, so
they are really not Green, are they. Just my opinion on these vehicles and my country.

I've seen an EV here in Europe that would fit my needs in Thailand if it was available, the Seat Mii electric. It's a conventional looking small city type hatchback with a 200km range for just over 20,000 euros.
Of course, they won't be available there but if they were it would be ideal for my trips to town and the beach and for that sort of money, you could afford it as a second car for a local runabout.

If I had the need and purpose, you wouldn't have to twist my arm too much to buy something that looks like this.
