David HoLamppost EV chargers are the answer to how you charge your vehicle in cities.
This is possible because when energy intensive street lamps were replaced by LEDs, there’s excess power for charging EVs.
All cities should do this. ⚡️

GonoMobil@evolvable @jan @davidho Hopefully in real life most „nights“ (locking the car until unlocking it again) also are longer than 7 hours…
It‘s sooo relaxing to enter your car in the morning, having it ready to go without the hassle and stink and noise of entering a petrol-station (aside from tire-pressure checks every now and then).

Get back into a gas car, drive it all week, then realize you have to fill it up right now, or else!
One less place to spend your time.

Martin Vermeer FCD@davidho Afraid it's too little. A high-pressure sodium lamp uses 1 kW, others less. Unless the cabling is upgraded. Needs to be 11 kW to be interesting.
Gabriele Svelto [moved]@martinvermeer @davidho most street had several lamps attached to a single line. Most lamppost EV chargers I've encountered are capable of ~20kw AC charging, downgrading to 10-15 during periods of high load
@gabrielesvelto @martinvermeer @davidho Most EV cars can only handle 11kW when using AC charging. Some Tesla's and a few high end cars can handle 22kW AC.

The answer to "how do i charge my vehicle in the city" is "you don't, you keep it out of the city". At least for big cities. Cars are not suitable for dense areas. Bikes and Busses are much better.

AnomnomnomalyIn a lot of UK streets, especially the millions of Victorian homes whose fronts doors step right onto a narrow path... The lamp posts is up against the houses, or the lights are actually on the house itself.
It's a partial solution to the problem.
They did that in my old town as a trial... Cables kept getting stolen and cars got unplugged all the time by kids walking past.
Pete@davidho
I don't think street-side charging should have any significant role in cities. Street-side parking is already a problem that would only be compounded by charging cables and bad behavior of people fighting for spots.

Nikhil Nigade@davidho this is brilliant idea, makes me wonder why I never thought of this before.
Once our elections are done, I’m going to propose this to our legislator.

Kokos 💠@davidho I think the old sodium lamps were around 1KW so they do have spare capacity in the cabling
Alex@rtnVFRmedia Suffolk UKthat picture is from the UK (looking at the registration plate of the car), but there's evidence of recent extra work being done at the base of the lighting column suggesting there may have been a cable upgrade (its possible to do this without taking up the whole pavement with modern plant, Cadent were doing similar for gas pipes in my town).
Using the space already occupied by the column does at least remove the requirement to get further planning permission..

SellaTheChemist@davidho You hear people complain that these points are very slow. Not surprising because I can't imagine that old streetlights with sodium or sodium/mercury lights would have drawn more than 1 kW and that's peanuts by EV standards.
Ironically the old sodium streetlights, that were invented by Marcello Pirani's group at the Phillips Research Centre in the 1930s, remain some of the most efficient light sources ever invented, running at about 70% conversion. #ClassicKit https://www.chemistryworld.com/opinion/piranis-gauge/5039.article

@sellathechemist @davidho That's very good! Probably comparable to LEDs equipped with phosphor conversion. But of course, longevity. It's a big thing to not have to have a guy with an access platform on standby to replace lamps when they go. Bigger cost item than the kWhs!
Chris Dudley@davidho It looks as though the cable stays with the car. That seems tidy to me.
tb@davidho A bit more complicated, but there is also the idea of putting the charging points into the kerbs.

kim_harding ✅@davidho but only if we can reduce all car parking to the level of one car to one lamp post
climate voter/radical oldie@kim_harding @davidho Encouraging people to park along city and town streets is a bad idea.
@davidho There are a total of 3 lampposts in my street with a total of 16 households with an average of 2 cars per household (32+ cars). Street runs at the back of our properties (30m from back door and nearest electrical outlet).
@davidho What's stopping me waiting until your tucked up in bed and swapping out your charger for my charger. Morning your car isn't charged but mine is ready to go

Krupo@fletch49er @davidho car alarm goes off when unplugged. And if you're really paranoid locks do exist for these plugs.
@fletch49er @davidho the car alarm sounding is a car specific feature.
The model displayed in the OP's top post is not what I'd consider a good robust design, and I see that the example is generating a lot of valid criticisms.
The arrangement like that used by the Flo network is designed such that the cable belongs to the pole. You don't use your own personal cable. You unlock the cable from the poke with your own charging app and get billed to your account. When done return the cable plug to the pole which locks it up.

There's a 1000 words worth of description....
@fletch49er @davidho funny but no, installations will scale with demand.
Real world proof: see this screenshot from just one small slice of Montreal, as of right now.
Legend: Grey means all ports in use. Green is available. Orange is high speed (DCFC Level 3)
bouriquet@davidho One of the advantages of LED streetlights was a reduction in energy consumption. This defeats that.
Electric vehicles don’t save energy: net effort to move mass is the same. Except the energy now comes from a large generator somewhere with generating losses and transmission losses. What generates the electricity? Coal, oil, natural gas? Nuclear? Solar? Wind? Does it pollute as much as a gasoline car with emission controls? System level impact? Think!

Stevez@bouriquet @davidho The same goes for ICE cars: How much fuel and electricity had to be burnt for your petrol to get to your local pump? To get cracked in the refinery? Oil to be transported to the refinery? And drilled out of the earth? And your car then throws away at least 60% of that energy away in a super-inefficient combustion engine ! Think!
@theron29 @davidho And one more question: what is the impact of lithium mining, transport and refining of the lithium, recycling (we hope)of the spent battery pack and replacing it with a new one?
Nothing is perfect. But which has less overall impact on the Earth as we know it today?
Will electricity companies have enough generating capacity if we all switch from ICE?

deBaer@davidho In many cities, including Berlin, the street lights were mostly powered by gas. When they replaced the gas burners with LEDs, they used very flimsy single-phase cabling that's OK for a few LEDs, but not at all for charging vehicles. That's why Ubitricity comes from Berlin, but has installed their system mostly in London…
Ian K Tindale@davidho this should also be a good scheme for charging phones, if you’re willing to lean against a lamp-post for about half an hour, using Qi2 (when Qi2 finally emerges as a thing)
𝔅icyclet𝓽𝓲𝓷𝓰@davidho Sorry to say that EV are part of the problem, not part of the solution.
Cities should be focusing on active travel and public transport.
Justin Derrick@davidho Yup, doesn't even need to be a fast charger - most cars are parked more than they're driven, so even 240V@ 10A (2kW) is plenty. For most small electric cars (50kW battery), that's a 1/3rd of a charge during a regular 8 hour work day, or 50% of a charge for a 12 hours overnight.
Nevermind the benefits of Vehicle-to-Grid (V2G) if that were enabled... Pay car owners to use 20% of their car's capacity when there's a peak demand for power, and top it up by morning. :)
RolingMetal@davidho I assume, this will be very slow AC charging.
@davidho LED street lamps have efficacy of 130-160 lm/W
Sodium street lamps have 200 lm/W
What do you mean by energy intensive lamps?
