Interesting to hear about the development process. Learning how to design the PCB will give you more control of the product. A few thoughts: 1. Low intensity sidewalk lighting might provide utility, reducing objections from neighbours. 2. Consider theft; it looks like the electronics box can be unscrewed in seconds. 3. Aim for a standard pole size so that the electronics can be fitted into various types of pole to blend in. 4. Get a quote from a board manufacturer like Pcbway to get an idea of cost. Keep going; pursue your dream. ☮️

These are good thoughts. Thanks for bringing them up. 1. Are you thinking a light on top of the post to illuminate the sidewalk? 2. Yes, the box is easy to remove, but the bolt is a security Allen head bolt. Granted you can purchase these drivers, but it's not as simple as dropping a Phillips screwdriver down in there. Later version also have screws securing the post cap. 3. Yes, this is a good idea. Currently we're using an off-the-shelf 4"x4" steel or aluminum post. 4. We've worked with PCBWay and several other board suppliers - they are amazing for quickly turning around inexpensive prototype boards.

@@chargeeverywhere For sidewalk/curbside lighting, the Post Cap could flare out like the brim of a square hat, with downward-facing lighting around the brim. Also, perhaps if the material used to make the cable terminal comes in a clear or white translucent etc, then where the power is coming out of the pole could show the status color. And bonus it's facing away from the residents and is easily seen from the charging car.

I love the invisibility of it. I think adding any kind of always -on lighting defeats that goal. However, an illuminated plug or ring around the plug, similar to the images already on your webpage, that's turned on by a very short range (or adjustable) proximity senor, either in the face or on the top, would be excellent when trying to plug in at night. It's easy to see this fitting into a mailbox post form factor as well.

I think from longevity perspective, you need to design the PCB while considering the clearance and creepage norms for industrial electronics. Also you may need some sort of coating or even complete potting of the box, this improves reliability over lifetime of the posts. Last but not least, you need to also perform some sort of accelerated testing (corrosion/salt spray, thermal cycling) which will give an idea where weaknesses exist in your current design. This gives you valuable input for both Hardware and Mechanics. Cheers.

This would make instalation of charging infrastructure much cheaper for businesses, landlords and municipalities. The only time external cables should be necessary is with DC Fast Chargers.

This way, the post can double as a mailbox post.

Something worth consideration, is a design that collapses into an in ground cavity, like a collapsible bollard. It protects the cable from the elements, and protects it from damage from cars going over the curb. It may also be worth considering one that is “duplex” with twi outlets. The electronics may benefit from being “potted” in epoxy. A commercial version as a street parking offering, with means of payment might be worth development as a product aimed towards cities. (However, if you pursue that, it should offer an RV connector, for food trucks to be able to ditch portable generators)

I love your design! A simple post is the most elegant solution. Here in New England we face some serious weather which with your current design would be risky as the outlet socket is too exposed. How about having a slide up collar cap which is held up by the cords connector. That way the cap lowers its self once the cord is removed. I would also leverage the edge of the electronics box as a light pipe so the posts edge is lit white, green, yellow, and red. White for availability, green the charger is active, yellow under charge, red charger failure. As far as connectivity, WiFi is a bit heavy as the coverage distance is quite large, while I’m not sure if the POS systems charger systems use is able to use Bluetooth and/or NFC both of which can offer a smaller radius of signal so people nearby are not snooping to the data stream. This is important is dense cities where this would be a sizable market. Lastly, what is the expected level of charging you are looking to support? With in a suburb space I can see Level-1 or 2, in urban spaces I can see Level-2 or 3 with more Level-3 fast DC charging in dense cities. As an example here in Boston we don’t have the sidewalk space in many parts of the city to even have street side charging. Instead we are planning a few sizable charging parks with 20~30 Level-3 fast DC charging stations. Allowing people to charge up and then move out in less than an hour, so someone else can charge up. Where we can have curb side it will likely be just Level-2. So while you are still experimenting consider what the power options you will provide. The bulk Level-3 gear will be in a separate vault space close by so you will still need a comm line to the vault to enable the higher voltage. A larger post with Level-3 might be needed.

Here is my advices, you are probably better than me to know what's shit and what is not, but I really know that the feedback always help. (6 points incoming) 1. Build modular if you can. Use standards communications (usb or others). Build it so it is SERVICEABLE. Being modular help this by identifying what works, what doesn't and will help with replacing parts easily. 2. Keep all possible costs low. This is especially important for mass adoption. If you use standard communications, and everything (like powering with an arduino or raspberry pi) you could even just sell the software, and have some videos or website explaining how to build it DIY, just providing some specific parts to comply with regulations). This could both improve your project spreading, but keeping costs down, and improving serviceability of the final product. Using standard communications would even allow you to sell diagnosis tools for maintenance "here what is not working, replace it, you can find a part here : ..., you can even just scan that QR code to get there, and here a QR on a video on how to service that part" 3. As you need to burry some electric cable from your house, maybe you could split everything : just some basic things in the post, the main control unit in the house close to electrical pannel. This will help with modularity, and keep maintenance costs down, as replacing the exterior unit will be cheaper, and less things exposed to weather. 4. I see that you are talking about wifi. You should maybe consider offering some kind of software (app ? cloud ? If you need some advices with that, I'm an android dev, so you know...) in order to allow easy identification of who is charging and how much electricity you are getting in order to simplify splitting the bills. I do not support AT ALL every apps and authentification for fast charging, this is stupid, just put a credit card ffs. But in your case, charging always from the same spot close to your home means that it makes total sense. This could also allow you to get a bit more computationnal powerif you split communication to your house, and maybe even the main switch. 5. I don't know if you though about it, but a locking mecanism to prevent the car cable to be stolen could be some use. You could get like some part (a chain ?) hold with a lock inside the post, and "customers" could put their lock to the chain. If someone malicious let something locked into, you just remove the chain by unlocking the owner lock, throw everything, put another chain and voila. 6. Evs are often sold with some regular 120V charger. You could probably put just some regular exterior outlet switched by some computer (arduino ?), with authentification like you probably already do, and just let people use their own 120V chargers. I think this could be a viable marketing strategy to do both, allowing even people not from your neighborhood to charge on your post through the authentification system or something like that. That's for later, probably, but you know. And last : good luck man. This needs to be everywhere. Roadtrips are not that common, you know, you don't get that each week. But if you had chargers everywhere, why would it matter ? Your car would be charged each time it's parked, that's the dream. That's even more convenient that gas station because car are parked most of the time anyway.

It may lock to my car, but it won't lock to your post. I know NACS is new as the charging standard, but I see a world where I bring my cable in this design, gets locked into place on your charging post, like on my car. While I'm charging, both are locked, until I stop the charge. This adds a lot of complexity on your side, but I see that as must as a long term design plan.

With Kia you can configure if you want them to unlock after the car is charged or after you unlock your car. In public... The second option is way safer.

I really like your modular design quite a bit, especially for servicing and maintenance which is a huge problem in chargers. Here a couple of things I would recommend: 1. Determine your market is residential or city governments. I think you are close on residential market. If you want to go into the other markets, you will need to consider different input voltages and phases as part of an existing infrastructure like street lights. 2. I would consider different input power disconnect strategy so that electrician is only needed during installation. Maybe consider an HVAC-style blade system so no worrying about torquing screws in terminals. Maybe this could be part of the wedge system or another accessed from the top. 3. Add optional small down lights for sidewalk/walkway to double function and help adoption. Residents may allow post if lighting is added which also has charging. I think someone else may have mention this already. 4. Support NACS plug and signalling upgrade as a module swap out as a selling point.

Mine had a silicone rubber gasket that seals against water with the fasteners outside that seal. I drilled holes and fitted it with waterproof cable glands for the two main cables.

@@emmettturner9452 Since this was printed, I filled the gasket "groove" with a somewhat soft silicone that was allowed to set up before assembling the box. It wasn't great. Since then I've experimented with printing TPU gaskets, but ultimately we'll have a foamed-in-place gasket in the final product - something like what you see in off-the-shelf enclosures like your's.

It helps distribute current between the two 240VAC planes on both sides of the board. It’s one way to keep things running cooler without thick copper layers - doubling up of the layers. I have a Grizzl-e that does this.

Interesting to see the different prototypes. Now that NACS has an official spec with a double sided cable I think it's a huge mistake to not just switch over to that especially since the majority of new cars 2025 and forward will use that connector. It doesn't make a lot of sense to use an old connector that'll likely never be innovated or updates again vs the new living spec everyone is moving towards. I'm interested to see what's next though.

@@MatthewGarbett Yes, no, and maybe. Let me explain. For now, the station side is what is called a Type-2 socket. This is the station-side standard in Europe and much of the rest of the world - and likely will be here soon, too. We want to use NACS on the socket, but this doesn't look like it'll be the standard - although we'll support it if something changes. Either way, the station side socket doesn't impact what vehicle can use the charger. You'll have a Type-2 to NACS or Type-2 to J1772 cable, and since you carry the cable with your car, you'll always have the correct one with you. Hopefully, this answers your question, and we want to be ready for you.

@@chargeeverywhere ok thanks for the answer. It was my understanding that after NACS was standardized it had the doubled sided cables as well. It's hard to predict the future so we'll see how it turns out. I imagine it won't be super hard to update them later on if you need to. Interestingly, I recently saw an EV with the cord built in. It would be interesting to see if that happens more in the future.

Type-2 looks preferable for this type of situation. NACS doesn’t have a latch on the handle so it would have to be secured and unlocked by the post for a secure connection, which adds complexity to the receptacle and adds a point of failure. So a type-2 to NACS cable in your car is the best bet.

I don't know why this just popped up in my feed but it's very cool! I like the suggestion that @Tim_Kent made. Warm white LED's on the sides of the post that shone down towards the ground could make an optional subtle sidewalk or street/parking light. Something that doesn't blast anybody in the face and I suppose is optional. How does a unit like this prevent cord theft? Could there be a mechanism where once the charging starts the cord gets latched in to the post and needs to be released by the app?
@chargeeverywhere
22 күн бұрын
Yes, a locking mechanism is in the works. Also, nearly every EV has the option to lock the cable to the vehicle, which prevents theft, but not an unwanted unplug. The lights are an interesting idea too and I’m onboard for subtle lighting. When I played around with white or colored lights, it got pretty brash pretty fast.

Would it be possible, to take the electricity from the pole, step it down to a proper voltage, then from that box run it down the sidewalk to each pole? The grid company could put their own meter on it and even do the billing per vehicle. What do you think? Does this exist?
@chargeeverywhere
23 күн бұрын
Yes, this is possible and a good idea. There is a company mounting "drop-down" chargers on poles like this. However, this does require a pole to be more or less where you need it (probably not a big issue as there are poles everywhere). The bigger issue is the transformer, new connection, and meter required for this setup. By powering our charger from existing power supplies (buildings) we get around new service connections, saving cost and time.

Because it has voltage on the socket at all times and no communication ability. The core idea of this project is that the power to the post comes from the house it is in front of. But that street spot is open to anyone, and random strangers could park their and get free charging. The post need to be fed from (or contain) and EVSE and that EVSE needs an internet connection. The EVSE only energizes the socket when an authorized vehicle is plugged in. That implies the need for a back end infrastructure like Chargepoint has, and I haven't heard the creator of this project talk about that aspect yet. But it will be at least as big an effort to create that infrastructure as it is to design the hardware.
