in the pre-pandemic world they had to implement a queue system for the charging spots, so you couldn't just park your car the whole day in one and had to move it out to let someone else have a turn.
I'm sure it'd be more costly for commercial work but a simple home charger infrastructure installation runs around $1k, and that's for a Level 2 (240V) charger. Although that doesn't account for the supplemental meter equipment costs.
A Level 1 charger can recharge say a Nissan Leaf from empty overnight. A single day's drive is far more likely to be at or below 20% of the capacity which is closer to 2hrs. For the average user that would be just fine.
A small number of time-limited slots with Level 2 charger could be provided for convenience, but even just allowing individuals to charge at Level 1 rates while their cars are parked would likely suffice in at least half the cases.
There seems to be this misconception that every EV will eventually need a dedicated fast charger and needs to charge to full capacity in 5 mins. But the reality is that, for a large portion of the driving population, a car tends to sit in place for large amounts of time and a modern 150mi+ range EV rarely get depleted in a day. A Level 1 charger would be more than enough for those people. Especially with public fast chargers available for those unusual situations where you need more charge very quickly.
For those who need more than that, an EV is truly not an ideal vehicle for them.
I also think that thinking of Level 1 as "chargers" and not "boring wall outlets" is a part of the remaining problem. You shouldn't need to bother with the costs for metering and accounting the delivered power at Level 1. Does Starbucks charge you a wall outlet fee to charge your cell phone or laptop? At Level 1 it can just be a "courtesy".
At Level 1 each car is basically the extra draw of one additional old school incandescent light bulb. Who seriously cares to measure that accurately?
You can do a rough math estimate at Level 1 and just add that overhead to your operating expenses per usual. Many places with existing parking fees the added overhead likely is a rounding error compared to the existing parking price. (Same versus apartment rentals or HOA/COA dues.)
Individual outlet metering is expensive and complicates everything, just install boring outlets like we've done for more than a century.
Exactly! So many people fixate on fast charging that they just don't register the magic inherent in your car and home running on the same "fuel".
And having heard from people that cold climates often have outlets like these in place for engine heaters to prevent engine freezes shows that infra for this can easily exist. Though it's probably more investment for 3-7kW capacity at each outlet compared to powering a block heater.

Oh I totally agree, but try getting an apartment complex to buy into thousands of dollars in electrical work only to shell out even more money buying "gas" for all their tenants.
My in-law has trouble getting his complex to fix sidewalks let alone do something like installing charging infra and providing electricity. If the $1k estimate was even close for commercial 120v charging infra, you'd still be talking between 10k and 100k in just electrical work.
But that sounds like something that could be easily turned into a market differentiator, so it's not to say it won't happen.
Perhaps tacking on a flat-rate fee to offset costs would be a strong middle ground as well. That concept is something apartments/HOAs are already quite familiar with, what with things like covered parking, garages, and even additional storage space already available as add-on charges in many places.
> Individual outlet metering is expensive and complicates everything, just install boring outlets like we've done for more than a century.
Somewhere in the eventual development of this tech could be something like a complex level charging system where an apartment could meter through the charger, since most modern IoT type chargers track this anyways. That way the infra is still just as simple as a dumb outlet.

This pans out at small scale, though I wonder how that pans out in the real world. The sticker shock of running that calculation at "worst case scenario" seems like an issue. With even 100 EVs at worst case using todays numbers (~60kWh capacity per car, $0.15/kWh, full charge daily) that number is nearly $1k per day. Realistically it'll be much lower since that full charge nightly is highly unlikely, but sticker shock is real.
I guess if you're for some reason running your cabin heating the whole time then I suppose you're reducing your range, but that's solved by not doing that perhaps.
The power grid hasn't melted even though the plugs at the parking spots are on a timer and usually run two hours from 0600 to 0800 so the car is nice and unfrozen when it's time for the daily commute.
Now when we are moving to PHEVs and EVs some people are _very_ worried that an EV using the exact same plug with the exact same load steadily from evening to morning will melt the entire power grid and the local wires and melt the plug. Dunno why.
Street parking is still an issue, but there are solutions for that too. The power could be pulled from street lamps for example.
But yea, the cabling needs to be checked by an actual electrician and they'll determine how many cars can be charged in the ye olde block heater system without melting any wires or tripping fuses.
The 1980's stuff can usually handle 8A continuous loads. They changed the standard some time in the mid 90s, those can handle multiple cars at 10-16A continuous depending on the main fuse.
Anything above that and you'll need to overhaul the whole field and people usually go for Level 2 capable cabling if they need to break ground for cabling anyway.
Of course, this would probably (?) be a bit absurd for street parking, that's true.
Source: My dad has his hobby car in a glorified tent during winter, works just fine, the roof is in a 45 degree-ish slant so any snow just falls off.
And I, every winter, see snow clinging to 45° roofs quite often. Slightly wet snow (also the heaviest snow) can even stick to vertical surfaces.
45° would also make an overhang more susceptible to wind forces, acting like a sail.
Methinks the number of stations will organically grow with the predicted amount of EVs an apartment will have parking on site. That’s how it started for me in 2015-2016!
This doesn't work in cities. None of those places have parking lots.
And don't say "chargers on all the curbs" because we can't afford to further entrench car supremacy and make it harder to reallocate space to bus lanes and pedestrians.
Put the chargers where the cars are parking. With vanishingly few exceptions, they're all parking somewhere.
I'm all for a less car-centric society, but it's gonna be easier to reach that future if we address climate change a bit on the way.
That would really be doubling down on the high cost of free parking. https://en.wikipedia.org/wiki/The_High_Cost_of_Free_Parking
Edit: Should have mentioned the climate change is one of the biggest components of the cost of free parking. Without all the government-mandated parking spaces for the past 60 years, there would be far fewer cars today. It's not too late to reverse that.
Where so they park? Put chargers there, then.
Put chargers where people park cars. Don’t awkwardly drive to a random place to charge.
For 75%? Of people that can be at home. For others work. For others the grocery store.
There's been arguments about putting them on lamp posts - ok, but again, cables. 1 lamp post for ~10 cars doesnt really work.

That must vary between countries, because I've seen tons of outlets on the outside walls of homes in Finland. They need a weatherproof extension cord, but it comes in handy for a lot of tools. Though most homes have at least a driveway, cars are generally shorter than homes, so they fit close by.
The cost of free parking and where to park should really be reconsidered in cities though, as with your image, those exist here as well and are really bad places to drive in. IIRC in Japan they require people to prove a car has it's own dedicated parking space before they're allowed to get a car
The issue as shown in the streetview image is that those are public footpaths next to the houses. If you tried dangling a cable from your home to your car (if you were lucky enough to get a spot outside your house) you'd very quickly be in a lot of trouble when someone trips over it.
Not seeing anyone coming up with a way to solve that pretty important issue.
This is where the incentive program breaks down and the 4- or 5-figure electrician quotes start for a lot of houses that were built in a time and place where natural gas powered all of the heavy appliances and panels were sized for 60- or 100-amp service.
Fancier Level 2 ones with Wifi and shit are up to 1k€.
There are just certain sections of the country where you'd either have to turn half of the streetlamps into a chargers (maybe a good idea?)...or make a modular battery swap gas station scheme....or stick with ICE.
A trip to the grocery store takes 30-45 minutes. If even 20% of the existing spots had a charger (even a modest rate charge), you'll get quite a bit of charge. Or if 20% of the parking spots at your workplace had chargers, you could leave it on the charger all day one day a week and charge very slowly (which as a bonus, low-rate chargers should be easier to provision than superchargers).
My town has on average 1 car per household, but I'd guess like 0.25 off street spots per household. That's a lot of infrastructure on public land.
It's just an electrical outlet. There are dozens of them for every parking spot already, in the house/office/building. Adding an extra electrical outlet isn't hard for a homeowner/lot-owner to do. This isn't going to have to happen overnight. It will happen slowly over two decades.
Regardless though, you're correct that it will take decades, but I think that this is one reason why a CEO wouldn't be all in. If it's going to take 25 years for a large chunk of customers to buy an EV, you still have a lot of cars to sell that are ICE.
It's just a normal plug, maybe with some components related to metering and billing included. Load balancing if you want to be fancy.
But I generally agree: unless you drive a lot and can charge at home (or at work, or both), you aren’t going to get very far ahead with an EV (and lots of L3 charging supposedly strains the battery). But they are also really fun to drive, so it might still make sense for some people to get them even if they aren’t going to be saving money.
Most people spend a significant time with their car sitting somewhere for at least that amount of time.
