Technology Electric Cars ...

[colin traveller]

IMO They should be kept to inner city useage ,,, and not allowed on B / Country roads .


For the simple fact you can hear them and if you're view is obscured by hedgerows etc. double bends , etc etc , you don't see them till last sec They are a hazard ....

I might buy a Chevy Bolt and put a rifle sight on the hood. Look out hedgebunnies.

What about Hybrids? They're just as quiet as full electric cars when they're running on battery. I know mine is.

Not encountered hybrids on the back road but a helluva lot of drivers that use fog lamps when it's Sunny ..


Dumb illegal and pointless

From what I know the EU is at it and such cars will have to make a driving sound in the foreseeable future.

Besides that you've the tyre noise which can be louder than some of the engines.

@colin traveller: Are you sure these aren't day driving lights? Mine function as fog, corner and day lights for example.

Electric car: 697,612 km to become green! True or false? - Damien Ernst

Author: Prof. Damien Ernst, University of Liège Very recently, the RTBF, a Belgian media outlet, published an article titled « Electric car: 697.612 km to become green! » I had given an interview to the journalist Gérald Wéry about this article, and I made some calculations. So yes, under...

A gasoline Honda Civic is as quiet as an electric car but that's another story. Consider this, the Chevy Bolt motor and drive train only has 13 moving parts. Basic routine maintenance on the Bolt is checking the window washer fluid, reducer/differential oil and battery coolant. Electric drives can easily last decades with little or no attention because of their simplicity. I know, I've seen many ancient perpetually neglected drives that run just fine.


This is part of a series of videos on the Bolt from Weber State University (WeberAuto on YouTube). This one is the teardown of the motor and drive train.

Yeah here in the Philippines it is slowly gaining traction. It would be perfect here given the short distances most drive, and the amount of sunshine for solar powered chargers. Most worry about the monsoon season when the flood waters come in. What is needed is an electric car to travel aroun the world to dispel the myth that they are brittle and range limited.

Pretty much every modern car I've come across can punch out 1200-1400km with a 5 minute fuel stop. For Australian rural drivers, that's where electric cars need to get to, to be considered viable. IMO.

Can anyone tell me what EVs are like carrying a load, say 500kg, or towing a trailer or van? That's the other perceived weak point for EVs down here.

As I understand it, the battery market is currently dominated by phones. When we start seeing 50%+ global EVs, will the price of those batteries still be dropping, or will the demand for raw materials get to the point where prices are pushed up again?

Finally, we already have brown outs in Summer when everyone comes home and turns their AC on. What's going to happen when everyone is trying to charge their car at the same time? Will these sustainable energy power networks be able to supply the juice to keep everyone going?

Audi E-Tron: 300 kW with up to 660 Nm (short time) and 560 Nm (longer than 60 secs), 95 kWh battery with a range of up to 400 km (WLTP standard) but 300 km are a more realistic figure, can be charged with up to 150 kW (if you find a station that can deliver so much juice). It can tow up to 1.800 kg.

 

[digrar]

What does an 1800kg tow do to its range?

 

[Junglejim]

Ford just invested $500 million on this company and they are releasing this truck in 2020...

[digrar]

And the price is, eye watering. Just under Aus 100K for the 370km range version. Assume that's way beyond best case scenario and drop it to around 300-320km, add in a load or a tow and it's range is...???

 

[Junglejim]

I have a feeling the future tech that Ford will be cannibalizing from that company will find its way on the F-150 and Ranger models.. thats more affordable. 300km range is plenty enough for most of the planet. There was one model of Ev i cant remember what,t was coming from israel that gives you the option to charge or just do an outright swap if you want a quick charge, i think

Why are you so against EV, let me guess you dont drink single origin coffee or wax your beard?

2nd hand Nissan Leaf electrics our of Japan are as common as cockroaches here in NZ.

All selling in the $10-20k NZD range.

They represent really solid and competitive up front value and long term total cost of ownership as parallel imported 2nd hand purchases,

A classmate who was 2IC of Google’s autonomous car project and has since moved on to Uber says the Nissan March was by far the best bang for buck of the competitive reverse engineering they conducted as at 2016.

Electric is getting there, slowly but surely.

The biggest problem is that people expect Moore’s Law to apply to electric cars(price performance improvement of double performance or half the price every 18-24 months).

But batteries are a chemistry problem, not a physics problem.

The good news is we are seeing considerable Lion battery capacity online akin to the LCD/LED display manufacturing capacity glut and price collapse in the last 5 years.

So while battery performance is not likely to increase more than approx 7% per year, battery prices are likely to fall a bit faster.

With proper water proofing electric cars can run under water. That's a real handy feature in flood prone areas or if you want to drive to Hawaii. The reliability of electrics is much better than that of piston engines and range is getting there, Chevy Bolt owners have shown they can get 300+ miles without being the slowest poke on the road. The gasoline equivalent eMPG for the Bolt is 125+ mpg. A 125cc Honda Grom can't get that kind of mileage. But the problem with the Bolt to me is the styling, it is worse than ugly, it's downright oogly.

What are your thoughts on the raw materials? Lithium mining is gearing up here in Australia, but what about cobalt and other metals required? If we're only keeping up with small phone and drill batteries, are we going to be able to keep up with a surge of much larger EV batteries? I'm assuming recycling will come into play here.

I have range anxiety... Australia in general struggles with many things due to low population density. If you're in the capitals it's fine, but outside of those population areas, roads are rough, due to low traffic, low funding, internet is slow, lot's of infrastructure, few users, no high speed trains for Mindy to get excited about, same same. EV charging points outside of capital cities will be the same issue. Slow uptake regionally due to real or perceived range issues, slow uptake = slow infrastructure upgrades.

 

[Marsch]

What does an 1800kg tow do to its range?

I've no clue and also couldn't find any numbers.

I understand that EVs maybe aren't feasible for rural areas where you've to travel long distances but for cities or more dense populated areas they seem to be a great alternative.

This here is one of the "Wittler-Brot" electro delivery trucks built in 1942.

IIRC it had a range of 80km at 60km/h. Imagine where we could be today if the automotive industry wouldn't have succumbed and collaborated with the oil industry.

 

[digrar]

I recall reading not long ago that electric trucks were common early last century.
