In order to match the 2,000 cars that a typical filling station can service in a busy 12 hours, an EV charging station would require 600, 50-watt chargers at an estimated cost of $24 million and a supply of 30 megawatts of power from the grid. That is enough to power 20,000 homes. No one likely thinks about the fact that it can take 30 minutes to 8 hours to recharge a vehicle between empty or just topping off. What are the drivers doing during that time?
ICSC-Canada board member New Zealand-based consulting engineer Bryan Leyland describes why installing electric car charging stations in a city is impractical:
“If you’ve got cars coming into a petrol station, they would stay for an average of five minutes. If you’ve got cars coming into an electric charging station, they would be at least 30 minutes, possibly an hour, but let’s say its 30 minutes. So that’s six times the surface area to park the cars while they’re being charged. So, multiply every petrol station in a city by six. Where are you going to find the place to put them?”
The government of the United Kingdom is already starting to plan for power shortages caused by the charging of thousands of EVs. Starting in June 2022, the government will restrict the time of day you can charge your EV battery. To do this, they will employ smart meters that are programmed to automatically switch off EV charging in peak times to avoid potential blackouts.

EVs have a feature that locks the nozzle in place. No one can remove it unless they have the key fob for that car.
Technology created by the free market that competes on the free market is great.
Technology subsidized by government to compete with other existing technologies that work just fine is evil.
If that is being a “Luddite” so be it.
All EV sellers here abide by that law. However, the "loopholes" you mention speak of remaining capacity, usually the batteries must retain 70 percent capacity after ten years or can be replaced under warranty. But if they fail, then they get replaced. What is nice, is that if they fall under 70 percent capacity then they can also get replaced. Early EVs were problematic, losing much of their capacity to retain a charge after a few years, which is why the law came into being.
Really? What do you think the cost involved in tearing up the entire parking lot would be to install underground cables to accommodate the 200 chargers would be?
And how would you protect the chargers attached to the vehicles over night from someone coming in and detaching the charger from your car and charging up his?
And vehicles have a device called a door lock that prevents them from being stolen..........How well does that work?
But I digress, what is the problem that your government is trying to solve by forcing you to purchase an EV?
“What is nice, is that if they fall under 70 percent capacity then they can also get replaced.”
Thanks, so they can lose close to 50% of their effective range (since most drivers know enough not run their EV down to empty). I think there were some other loopholes, like road hazards not being covered, etc.
“Really? What do you think the cost involved in tearing up the entire parking lot would be to install underground cables to accommodate the 200 chargers would be?”
If you’re as rich as apartment owners, who cares what it costs!!!
(don’t laugh, people who think this way now run the country)
Exactly. When you get down to it, the EV was a fun buy.
FWIW, my wife’s other car is guards red Cayman S. Premium fuel ;-)
Zoom zoom.
“How many units vs. how many chargers? I saw no mention nor any photos of the on site charging systems. Maybe you could provide them?”
Why do’t you click on the polaris link and read the description? You said apartment complexes don’t have chargers. I showed you they did and more are being added as time goes on.
You are hung up on theft. Do you think there is not a process to stop this?
From Polaris apartments:\\
Imagine everything you need, right where you need it. The View at Polaris is a gated community conveniently located just around the corner from Polaris Fashion Place, featuring modern one and two-bedroom flats. The community is at the forefront of modern living with a doorstep recycling service and electric car-charging stations.
You appear to be up on this stuff and EV.
What are the total Gigawatts coming on line for the 177 plants and when will all 177 be operational? How many plants are being shuttered in the US in the same time period and how many GW are going away? Shed light on how close the 177 are going to be to where the EV growth will be concentrated.
War-torn Congo is major source of most cobalt needed to make Li battery technology. Since the west became politically correct, China controls majority of supply chain of cobalt mined in Congo. China also has a plan to be all EV within next 10 years if my memory is correct. Do you see any geopolitical issues related to EV that involve human rights abuses in Congo, China, and China’s antagonistic foreign policy towards the US that will dampen the enthusiasm or dreams of the EV political-industrial lobby?
Hmmmm. That’s about 25% of the sales figures for the conventional F150, which seems about right. We conservatives tend to think things out thoroughly before we make a decision. The batteries in these vehicles end up worthless and difficult to recycle and dispose of, and the capacity and the infrastructure necessary to keep them going both doesn’t exist and will be difficult to build up. If I was going to make a decision on a car based on emotion rather than logic I’d rather buy a Hellcat to replace my Charger Pursuit than a Lightning.
25% of cars in the road being EVs isn’t going to happen, let alone 100%.
“Technology subsidized by government to compete with other existing technologies that work just fine is evil”
Every item we use today from computers , appliances on down was subsidized or was given tax breaks by the US gov’t at one time or another.
Every manufacturing process or nearly all was subsidized or helped by the US gov’t at one time or another and most still are from oil comapies to agriculture.
Solution is simple; put a small trailer behind the EV and put a generator in the trailer, run an extension cord between the EV and the genny, problem solved. Or how about this, trailer with windmill generator, now we have perpetual motion. :)
Rapid charging; Search: Niobium anode battery. Engineers are working on solutions.
(My car runs on gas.)
How about ammonia powered fuel cells? Power from pee.
(Off to nap!)
Gas stations were not nearly as common not long ago. Supply and demand led to more.
Likewise with charging stations: as demand increases, so will supply.
We’re still don’t have common gasoline supply at home.
I have an MSEE and 40 years industry experience. Despite that, I know that watts (or kilowatts, or megawatts) is a unit of power, energy per unit time. One watt is equal to a joule per second. One watt-second is a joule.
Ignoring transients, and just thinking about steady state (and for most applications, 10 minutes is steady state) the charge on a battery is usually specified in amp-hours, with the battery terminal voltage being implied. So a 12 V battery charged to 100 amp-hours would have a charge equivalent to 12 x 3600 x 100 = 4,320,000 joule.
Tesla touts their supercharging stations as 250 kW chargers, that can provide 200 miles of charge in 15 minutes. At 50 kW, that would be 1:15 (75 minutes.) A home 115 VAC outlet can only supply at most 1.8 kW, roughly 35 hours for the same result. Using "dryer connection", 30 AMPS at 220 would reduce it to a little under 9 hours. Again, an average commute of 30 miles would require over five hours charging on a 115 VAC household current, per commute.
Subsidies. And other federal crap: “Federal law requires car companies replace current batteries if they fail within 10 years.”
Power from pee? As if I need more encouragement to drink more coffee and beer.
The EV industry is doing very nicely with minimal and decreasing subsidy. Teslas are among the most common vehicles around here, tax credits long gone.
