OK everybody, time for a sneak peek into our Electric Future.
Electric Vehicle charging stations costs a ton of money to properly construct and some cities struggle to add increased capacity.

So what if long lines at petrol stations turn into long lines at EV charging stations?
My buddy, Kyle Conner, has a grand ol' time in Las Vegas, where 1/3 of the available charge stations are down for repairs.

 
Just curious. How long does it take to charge an EV? And what do the owners do while they're waiting?
 
Charging is the biggest problem with EV's that I see. It takes 5 minutes to fill up the gas tank. How long does it take to charge an EV? And how often? What I find on Google is, generally, it takes hours. I suppose if you have a garage at home, you could install a charging station, but a lot of people don't have that option. I have to park on the street, and I can't run an extension cord out my front door to charge my car. Then, especially since Covid, I don't drive very much. I might only put gas in the car every 2 months. Will an EV lose the charge just sitting idle for days at a time? Or overcharge and burn up the battery if it's left plugged in and unused for days? I'm all for EV's and doing everything we can to get off oil dependency, but until the practicality of charging them gets worked out, I'm afraid we'll be stuck with gas vehicles for quite a while, I'm sad to say.
 
Imagine lugging your battery to a charging station when you run out of juice two miles out of town or half way down an offramp.

And, is the heater or air-conditioning functional whilst on the charger?

A quick charge (20%) can be done in 20 mins if the charger is high capacity
A full charge can take a couple of hours

LOL
As far as I have seen the batteries are not removable

And that's one reason I'm never going to buy one. I can fill up my petrol tank in a couple of minutes.

I was listening to something on the radio yesterday about the relative costs of petrol and electric cars. An electric car costs substantially more to buy than an equivalent petrol one, but the fuel only costs about half as much per mile. The question posed was this: Given average mileage of say 7,000 per annum, how long would one have to own an electric car for the savings on fuel to cancel out the additional purchase cost? There were a lot of ifs and buts about resale value and so on, but the basic answer was 11 years. I only drive about 2,000 miles per annum, so for me an electric car would pay for itself in around 30 years. I don't think I'll bother.
 
^ we also cannot currently supply enough electricity to power even half of the transportation in the world.
 
The radio program I was listening to yesterday also talked about carbon footprints. If a person was faced with the choice of running an old petrol car for several more years or replacing it with a new electric one, which was greener? The answer was that, depending on annual mileage etc, it could well be better to hang on to the old petrol car. The carbon footprint of manufacturing a new vehicle is higher than running an old one and much of the electricity used to power electric cars is generated by burning fossil fuels and has a carbon footprint of its own.
 
For me, an electrical car would not be practical. I can drive a couple of hundreds of mile of day for work.
To recharge, would involve a few hours versus pulling up to a gas station and get out of the station in 5 minutes. Also, I live in an apartment building with no access to a recharging station. Everything would have to be planned and sit around waiting for the electrical vehicle to be charged.
 
Early days yet folks.

EV's demand a whole different mindset about the type of vehicle we drive in the future and how we will charge and store the charge.

This kind of reminds me of the "I am never giving up a horse and wagon" because who knows where I will be able to find a gasoline station?
 
Here in america we'll solve it the same way we solve everything else. Selfishness and violence. There will be fughts and stabbings at these stations. Just cuz our technology changes doesn't mean we do.
 
I'm just going to mention that when I charge my adorable HP Noise Cancelling headphones on my laptop and then wander about the house listening to whatever I want for 20 hours...if I imagine explaining this deviltry to my G grandparents and showing them that the battery is some teeny little weightless amalgam of rare earth metals and micro-circuitry....I am sure they would laugh and of course think I was from another planet.

When I look at a birthday card that plays a song for 20 seconds....and I did this when I was working with an organization developing its Strategic Plan for the next 10 years in 1995, I love to point out that this card contained more computer capacity than existed in the year I was born.....which is within memory.

We have tended to under-estimate our capacity for tech advance because the petro industry has made this an existential issue for shareholders like me...but be patient mon cher....all will be revealed in its own time.

And I suspect that seeing Russia try to hold the world ransom in order to steal the Ukraine will push all of this forward as geo-political reality pushes Elon Musk out ahead of the Russian petro-oligarchs...for better or worse.

That is a fascinating question.

Thanks to Kyle Conner, I've learned that recharging times depend on the battery's state of discharge, battery-pack temperature, the car's on-board battery management software, and the charge rate of the station equipment.
When you plugin to recharge, the station charger has to login to the vehicle's battery management module. The vehicle's software tells the station charger the rate "power" can safely be delivered to the battery-pack.

Most EV's can go from 10% to 80% state of charge in about 45 minutes. But if the battery-pack is cold it will take longer.

YES!

That's what I heard from an EV engineer. About 11 years for the average EV purchase to break even with the cost of petrol power vehicles.
All the fancy, premium-priced luxury EV's on the market will take waay longer than that - if the cost ever breaks even!

Watch out for the Rivian R1T electric truck. Go heavy of the luxury stuff and you the reach $100k:

That could be a problem (and deterrent?) in northern climes.

Do the batteries drain faster in colder regions?

Yes. Your range drops about 40%.

One reason is just battery performance but the whole time you’re driving you’re using the batteries to heat the interior. Heating in a petrol engine is basically free byproduct.

Alistair nailed it!

Batteries don't like cold. Not only do you have decreased range but cold batteries resist recharging.
There are EV's that have on-board battery preconditioning, stealing range to heat the battery pack, so everything is nice and warm when you finally get to the charging station.
 
Gotta say though...I see more and more EV's around here all the time.
