    Robert Llewellyn (previously of Red Dwarf fame) covered this idea eight years ago (July 2017) on his 'electrify' channel:

    > The simple and very commonplace lamp post will soon become a ubiquitous charge point for electric cars. They charge at about 5 kW, or 16 amps, not super fast but overnight charging is all most drivers need. Ubitricity is a German based company who've come up with a simple, cheap to install and well managed system for more people on more streets to adopt electric cars.

    Do these chargers require payment for the charge?

    What prevents "squatting" at a post (either with an EV or an ICE)?

    Just thinking of my neighborhood (THs, not flats, but still no dedicated parking), there's a lamp every 4th or 5th home, and most households have ~2 cars. People mostly park in front of their house today - if you have an ICE, but also a lamppost, it's a negative - you no longer get use of the closest space (or, you take the EV spot from an EV).

    The neighborhood solved this by allowing a charge cable to the spot closest to your house. But, that's expensive to install, so not many have done so (electrical panel on back of house, parking on front, so interior cable pull through finished space of home, charge unit on front exterior wall, then conduit through yard and public sidewalk for the cable run to parking). Of course, this doesn't help with apartment parking or true public street side parking (our neighborhood own the parking lot as a shared amenity).

      The model I have seen is that there's a cost for charging as well as parking after charging has completed. You get 20 minutes after charging has ended for free but there will be a blocking fee afterwards as long as the cable is still connected to the car and will be charged as part of the charging fee. If someone charges their car and then disconnects the cable and blocks the spot, they will be towed as the spot has a notice that it's only for charging devices.

      I have seen those attached to light posts here in Germany but they all are in front of public area, not private houses so I guess it's only for charging, not parking.

      In another point, if it's in front of a private property and the owner plan to occupy it for themselves, it would not make sense to install charger there as even when the owner is not charging, no one else can use.

      I'm not sure about these particular ones. But I've heard that some similar chargers can get a unique ID for your car through the charging cable and use that for billing.

    It's interesting how this sounds like a cutting edge experiment, while this is a common thing to see in Germany and other European states for quite a while now.

      I live in the UK; my postman walks up to my house and posts my letters through a flap in the door. I grew up in Australia, where our postman used to ride up to our letterbox on a postal-service-issued motorbike, because the suburban houses are too far apart to make walking economical.

      The fact that putting EV chargers in lampposts works in Europe doesn't necessitate that doing so will work in the natural environment, built environment and cultural context of the US. They have to do their own assessments to work out the best solution to the same problem in a different context.

      • darkwater 19 minutes ago ago

        Well, if we are discussing the scenario where people live in tall building with no private parking available and need to park the car overnight on the street (which is the scenario depicted by the study)... It sounds a lot like your average European city.

    • fumblebee 40 minutes ago ago

      Indeed, the several streets around me in London just had hundreds of EV chargers attached to lampposts.

      • dboreham 16 minutes ago ago

        I saw them in London a couple of years ago, and they looked like they had been there for a long time then.

      I think the "bold innovation" framing partly because the current administration is making green technology a though crime, and partly just the ambient American tendency to describe any incremental improvement as groundbreaking.

      Grants are given to those that can make the mundane seem new and exciting.

    In a documentary about a homeless encampment (in america) I viewed not long ago, the residents had spliced into a lamp post to provide power to their and their neighbours tents. It was truly a hacker inspired, move fast and break things approach.

    This research seems to be inspired by the same content and appears to be an attempt to commercialise the same technology.

      I can’t wait for people and companies to realize “oh no, we only wanted to give easy electricity access to rich people’s cars, not to the homeless people, let’s add another layer of dystopia to fix that”

      • ta20240528 37 minutes ago ago

        The homeless folk can nick the nice thick copper to strike back at the establishment. Or to by drugs.

      • rbanffy 2 hours ago ago

        It's just a matter of DRM-ing the smart connectors.

          Maximum fragmentation, everything else is communism

      • potato3732842 2 hours ago ago

        And after they implement the dystopia they'll inevitably use it to go after petty deviance by people who are rich enough to pay fines and leave the homeless who were the pretext for the dystopia un-bothered except just enough to let the useful idiots continue to think that that is in fact the purpose of the system.

      there are actually junctions (and sometimes complete with outlets) in many lampposts so city employees can use them to power their equipment

    The paper is here, but unfortunately this government funded research is not open access.

    • ncruces 3 hours ago ago

      I thought this was mostly about what kind of chargers are in there. But since the paper is not available, I guess we don't even know that.

      I guess an open question (at least for me) is whether, in an urban setting, it's better to install a dozen fast chargers, or hundreds of slower chargers – like two for all 100 street lamps in an area.

      What's more useful? Particularly in areas where people do drive a bit (the school run, shopping, whatever) but don't drive that much (they use transit, no huge daily commutes).

      For me (apartment, shared garage, hard to adapt) I guess a more easily available but slower charger that replenishes the few kms that I drive every other day during a night seems more useful than scheduling a couple hours on fast charger on the supermarket… just to get there and find it's unavailable.

      But they only installed 30 chargers, so it'll be hard to draw conclusions.

        Pricing always seems to be ignored. Sure, my local council installed chargers in the village car park for people without off street parking, but that’s 50p/kWh compared to 8p for me charging at home.

        • rcxdude 14 minutes ago ago

          This. The big inequity around being able to charge at home is the huge difference in price. These slow overnight chargers need to be very cheap to move the needle on EV accessibility.

      • keyringlight 3 hours ago ago

        Another aspect I'd wonder about is the cost for whatever organization is responsible for maintaining lamps in a district, presumably a slower charger is a lower specification and would be cheaper and more likely to be widely fitted or for the project to be approved in the first place, and limits the demands on the local electrical infrastructure. Once the initial install is done in a lamp it would seem that upgrading in future would be a smaller hurdle.

    I've been using these in London for at least eight years. Strange to see it written up as a test here.

      Someone will no doubt be pitching this new technology for the YC 2026 intake

  • jcarrano 2 hours ago ago

    That was the first product released >10 years ago at my previous job [1]. The idea did not quite catch on, though, and the product was repurposed (successfully) as an OEM charger. There is not a lot of power available on street lamps and charging at 3.6kW is kind of slow. Consider that with almost the same hardware (especially the same expensive parts) and three-phase current, 22kW are possible.

    It might turn out differently in the US, but it is hardly a new idea.

    • ninalanyon an hour ago ago

      3.6 kW gives between 10 and 20 km of range per hour of charging depending on the vehicle you have. This is plenty fast enough for overnight charging.

      • micromacrofoot an hour ago ago

        Yes I've never bothered with a higher output for my own home charger, a standard outlet is plenty if you're parked every night

  • maffyoo an hour ago ago

    ive always wondered why, in "day stay" car parks (commuters etc) they dont have 6 to 8 cables from a charging point that can all connect to different cars and then do round robin charging. This solves the problem of one person being connected all day and preventing others from benefitting. This way a number of cars can be charged up without the inconvenience of just one person being constantly connected. We have chargers at work where this solution would prevent all the car shuffling and aggro associated with people managing access. in our case 3 cars could charge in a day, so 3 cables available to three spaces and charging done round robin. Probably not a novel idea but one id like to see implemented

    • gwbas1c 28 minutes ago ago

      This is a very solved problem. EV chargers can change the rate at which the car is charging.

      I have a double-charger at home. If I plug in one car, it gets 40 amps. When I plug in two, both cars get 20 amps until one finishes, then it does a 32/8 split with the charging car getting 32 amps and the idle car getting 8 amps.

  • dboreham 13 minutes ago ago

    Presumably most US street lamps are 120V which is probably why we see this idea implemented in other countries that have 220V power everywhere.

    Also worth noting that many towns in the US don't have street lamps or only have them in the CBD.

  • infecto an hour ago ago

    Just what I know about the majority of America, this seems like a terrible idea. Most downtown areas in America are pretty empty. This includes Kansas City. There are pockets but it’s not like a uk city where you have the style of small connected labor camp homes and it’s the norm to park on the street. I would much rather see multi unit buildings install these.
