Electric Cars - the discussion continues.

A big challenge will be electric trucks. Until that happens they'll still have to drill for oil to move the world's freight. I think there might have been an electric powered semi-trailer recently that did a considerable mileage between charges. Don't know if it was loaded or not.

That's an awful lot!

 

Do you think they could make THAT many so quick.

Setting up to mass produce these vehicles should be lots easier and cheaper than for ICE cars.

 

They should have mobs fewer components.

There are certainly challenges for long range trucking although there is a hydrogen fuel cell semi that can do 1200k (Nikola One) I think most truck companies have something in the works.

I don't think it will be very long before we see these vehicles on the road certainly ver the next decade.  Smaller trucks are already on the road.

Amazing! Why isn't our media proudly screaming out about these Australian advances????

 

A viable electric heavy truck with 350k range and ten year battery life!

 

That's a big step forward.

Police in Fremont California were pursuing a felon in a Tesla patrol car when they had to let them escape because the car battery ran flat.

I believe the system gives plenty of warning of that possibility. I wonder how trustworthy your source is.  or maybe fool proof doesn't cover police use / training. .( Perhaps they said "freeze" and the audio picked it up) . Nev

I wonder if the siren started to lower in pitch 

 

 

[facthunter]

 It does when you pass other cars.  Doppler effect..  Nev

I learned last week that LED lights draw a constant power. As voltage drops, they draw more current, flattening the battery quicker. Filament bulbs follow the old V=IR so as the voltage drops they draw less power.

My son picked  up his new Tesla yesterday. He lives in Wellington and picked it up from Auckland. He took this great picture on the drive home.  Alas nothing ever goes totally smoothly, he got a stone chip in the windscreen.[ATTACH]50350._xfImport[/ATTACH][ATTACH]50351._xfImport[/ATTACH]

No, I saw that news story too.  It was human error though, the previous shift forgot to charge the car.

Did nobody notice.....

 

The American electric police car has a BULL BAR !

 

There should be a big heaadliine in the media to tell all those doubters that there is a Tesla designed for Australian roads!

 

 

[spacesailor]

And there's one flying in space, More miles under the wheel BUT not on the odometre.

 

Should be booked for not recording to Actual mileage.

[Marty_d]

If they disconnected the wheel from the axle and gave it a perfectly balanced spin, then got an odometer to read the revolutions without touching it, it'll have pretty much endless miles on the clock.

 

Here's a question for those who are cleverer than I - what would stop the mileage?

 

1. Death of the electronics from UV exposure and micrometeorite strikes
    
   
2. Too big a number for the odometer to display
    
   
3. Gravity of the rest of the car eventually pulling the wheel back into contact
    
   
4. The spin given to the wheel providing stability that the rest of the car doesn't have so eventually it would either drift away from or into the car
    
   
5. Both wheel and car impacting Mars?

OF course, it's the P factor, remember your training.

Which police force's jurisdiction covers space?

 

 

[spacesailor]

NASA, of course,

 

they can do whatever they like, Policing  space BUT polluting IT MORE !.

Oh Electric car thread.

 

I have owned 4 of them over the last 4+ years, daily drive in a Tesla S, 87,000 kms now, and own a Geely Emgrand EV and a BYD E5, both with 55,000kms. I sold a JAC EVi6 a few years back at 35,000kms.

 

I also sell about 20 EVs per month now out of my Stealership. The Geely and BYDs are my Demos.

 

I don't know everything about EVs, but I know a bit. What would you like to know?

A big challenge will be electric trucks. .

 

Many 1 to 3 ton trucks around Chinese cities now, they are awesome.

 

The EV trucks accelerate like normal cars from lights, none of this nonsense of nearly coming to a stop as they try to find second gear up a hill, and of course don't spew smoke over people walking along. Then there's the noise, the lack of it .

 

Should be law to get rid of the diesel equivelents out of cities..

What's the nominal service cost and interval?

 

 

[facthunter]

Minimal I believe. It could be designed for self monitoring, as a lot of digital stuff can be. The INFERNAL Combustion engine is a dinosaur. Having explosions inside your engine is not as attractive as having magnetic forces doing it quietly and just spinning on a couple of sealed ball races.  Nev
