Ok, so there's a key point here, and that's that fast charging is not meant for the home! You can fully charge an EV overnight on a 7KW charger. You don't need a fast charger at home. The other thing is that home chargers are AC and the car converts the current. This means that there's a cap to how much power you can give it. For example, my car can only accept 11KW and that's pretty typical. So 22KW chargers are a waste at home today. Maybe you'd need a fast charger at home if you never sleep. But the majority of people spend at least 7 hours at home. You'll always wake up to a fully charged car. Why do you need anything else?

Hell I park my car in an underground parking garage, and it's been a whole discussion about who wants to and how they want to install 7kW/11/kW chargers. In the meantime I just charge it on the wall plug now and then. Yeah sometimes my battery is not fully charged, but I hardly ever drive 450km in one go anyway.

  A few years ago one of my neighbours asked for a socket in the underground car park. I assume they paid the full cost themselves, although it probably wasn't that much -- the electrical supply to the building including the meters for each apartment are just behind his parking space. They installed a normal 16A 400V 3P+E plug (the big red one), which is an easy 11kW. There isn't any sort of 'car charger' on the wall, just this socket.

> You don't need a fast charger at home. This is such an arrogant statement. I may not "need" 3 petabytes of storage for my home media server, but I have it. I may not "need" a 64-core Threadripper 3990X workstation with 256 GB of RAM, but I have it. I may not "need" enterprise-grade networking and WiFi gear, but I have it. I may not "need" a 60 kW Kohler diesel generator, but I have it. > Why do you need anything else? Because he wants it. The same reason I have everything I listed.

  You're the one being arrogant here. If what you want requires most of the city infrastructure to be rebuilt then you can pay for it. If you can't afford to pay for a new gas electric plant plus externalities and new poles with thicker wires then tough. Don't demand handouts.

  The ability of getting everything one wants just because one can is not a good thing, in my view. Also, how is this relevant to the point above? One point is it's too expensive - so even if he wants it he might not be able to get it in the current reality. The counterpoint is that you can charge your car with a slower charger.

  Please calm down. No one is attacking you. The point is, MOST people don't have a 3990X at home, because they don't need it, and MOST people won't have a fast charger at home, because they don't need it.

  >This is such an arrogant statement. It's not an arrogant statement. A lot of people don't understand how electric cars work. It's one of the biggest things holding them back. I still hear people saying "I don't want to spend 30 minutes recharging every week" when you don't need to. You can plug in a car overnight. But people struggle to understand that you can wake up every day with a "full tank" which is something a fossil fuel vehicle can't do. It requires thinking about your usage of a vehicle differently. >Because he wants it. The same reason I have everything I listed. I ask the question because, again, people don't understand how electric cars work. A lot of people think a 22KW charger at home will be like a 22KW DC charger. It's an attempt to gauge the actual reasoning behind wanting it. If his reasoning is to be future proof, then that's fine, it's perfectly reasonable to want that. But if his reasoning is to charge at 22KW then it's just a misunderstanding and something we can help him understand. Don't assume everyone asking questions is being naive or dismissive.
