> There is no way to communicate when you are charged up that way Cant' the car do it?
Or ya know.. the pump, like has existed for decades..

This is basically how USB C became a thing. A group of engineers at Google created the connector design and then gave it to the USB standards body to use as the next gen.
Citation, please. More bluntly: I simply don't believe you. Google has absolutely none of the expertise required to put such a connector together. It requires a very specific set of skills in chip design, signal integrity, and connector design which Google has none of.

Tap & Pay with a ccard still requires you to fiddle with a station and slows you down. If you are plugging in at home (which is our target market), the fewer interactions needed the better. Imagine every time you get home you need to take your wallet out, tap the machine, wait for some 3rd party api to talk to the charger in the dimly lit basement, and then and only then you can leave. This is like 30 seconds of your…
This would be infinitely better than the current model, where you have to install a bullshit app, which doesn’t work over 20% of the time. I’d happily pay $0.30 per charge session to just use standard NFC or chip payments. Also, why in god’s name would I have authentication on my home charger?
As an added bonus, when you have family or friends visiting they can pay to charge as normal (at presumably a slightly less attractive rate).

They could, and many do, but the difference is that those types of interfaces are mandated/regulated while EV charging is not. Guess what's slightly cheaper when amortized across tens of thousands of customers in the products lifetime? Not to mention the amount of data that could be mined from those customers by having yet another app on their phone with bullshit location permissions "for the best user experience." E…
So solving this problem would be as simple as mandating/regulating it? Sounds like a no-brainer to end this debate, standardize things, and allow the build out to happen in a quick and standard way across companies. With all the EV goals that various countries are making, this seems like a foundational part of it. Consumers aren't going to buy into EVs in mass until charging in a solved problem.

IMO that would be better solved by mandating tap and pay payment at EV charging spots. Integrating payments into the charging standard feels like a wild overcomplication by comparison.
Not only that, how do you even propose to do it? If you just send the payment info via the charging plug, now you have to worry about the payment info being stored in the car and potentially stolen if the car has any security vulnerabilities, including in the charging port. If you use some kind of tokenization or similar then you're inserting third party payment processors into the system and they'll be wanting a cut…
It is customary when borrowing someone's ICE car to pay for the gas used by returning the car with as much gas as it had when you borrowed it, or even with a full tank. I'd expect people will want to continue that custom when the car is an EV.

Have you done any road tripping in an EV? my experience of the app-based charging landscape has been complete horror; apps don’t work, chargers don’t start, payments don’t through.. Just last month was a new app at McDonalds in Sweden, that one asks me to, in the freezing cold, scan a dirty QR code sticker, which takes me to a website I’ve never heard of that wants me to manually enter credit card info, like a phishi…
But why not just have contactless bank card payment? Yeah it is a pain, I have an electric car, but only because they force you to use their broken apps. All they have to do is let you pay with a bank card and it'll be just as easy as buying petrol.

Just go try them both. CCS2 Has separate AC and DC conductors, and the plug is huge owing to having 2 pair of charging pins and backward compatibility. They are more awkward and heavier than a fuel pump, and significantly heavier than the Tesla plugs. It's terrible.
> They are more awkward and heavier than a fuel pump Really? I don't doubt that Tesla's plugs are smaller and lighter, but it always seemed a bit caricature-ist about people saying how horrible the CCS plugs are and that they weigh like a million pounds or something. They certainly never seemed heavier or harder to manipulate to me compared to a gas pump, so I just never understood this complaint.
Parking lot style EV chargers mean that I'm frequently pulling the charging cable across the front of my car and trying to plug the cable in straight while the tension on the cable is pulling it sideways. It frequently means it's a two hand job, one on the cable to keep in straight and the other guiding the plug in to the port.

Yep. Regular petrol stations figured out pay at the pump decades ago. Why is this such a problem for EV charging?
Companies don't want want the hassle and expense of PCI compliance across their charger network. If it's just session auth shit going across the wire, they only need to worry about PCI compliance on the back end. By collecting lots of info about you, they get a lower processing rate because the transaction is lower risk vs a swipe/tap. They can save on transaction fees if they consolidate charging sessions; say you d…

There are 7,869 locations and 15,661 CCS ports in the US and Canada (versus 2,297 locations and 25,247 Tesla ports): https://afdc.energy.gov/fuels/electricity_locations.html It's plugs on chargers and inlets on cars. It'll be a slow and tedious process.
I didn’t include the crappy L2 destination chargers, of which there are a whole lot more of that support teslas. I was referring to the L3 superchargers / fast chargers or equivalent. The majority of the ones you linked are L2 chargers are are not that useful outside of destination charging.
