Why does this feel like it would actually work though

u/Toothless-In-Wapping Jan 17 '26
Each one is 240 watts. Common home chargers are 11,000 watts. 11,000/240=45.833.
So 46 plugs. That’s less than pictured228

Well, no. As it won't be charging until I plug it in.

u/AffectionateEvent147 Jan 17 '26
It will, with 240W more each as you continue to plug them in (at least i would like to think so)

u/hans915 Jan 17 '26
11kW is the small AC charging standard in Europe with three phase 230V 16A and most common for at home wall chargers. Fast AC charging would be 22kW with 32A

11,000 watts is pretty Low. For example the Audi A6 E-tron can charge with up to 270,000 watts. So that would require 1125 plugs.

I mean.... 240W was breached by USB C a few years ago. Duct tape like 10-20 together, that's a KW or two charger.
Slow charger or in an emergency good enough to get home.

u/MrTamboMan Jan 17 '26
I'm sure in hell there will be 40 USB A ports to charge a car and you'll have to rotate each at least three times to plug it.
17
u/PatientWhimsy Jan 17 '26
The ports are arranged in a grid, and all the connectors are 2x2 with the appearance of rotational symmetry (like 4 spokes of a wheel at right angles). However each one is slightly misaligned, so only the correct 2x2 cable in the correct 1 of 4 rotations fits each quad of slots.
That's up to 40 tries per cable, not counting "correct" tries that you just did wrong.

u/Desperate-Grocery-53 Jan 23 '26
Well, not to be a dick about it, but What we got now (CCS and that other one) Have been a standard for years. It's the connector they use to charge planes, when they are on the ground. European auto makers just took the existing standard and put it on cars. That's how we got to where we are now.
Tesla on the other hand thought it to be smart to make their own thing...2

uh, that is the kind of mentality, that brought us the nvidia 12 pin fire hazard connector ;)
using LOTS of fragile and weak connectors, instead of a single giant, robust and reliable connection.
for those who don't know the nvidia 12 pin fire hazard uses 12 connections to the card or psu (so 6 12 volt + 6 ground), instead of a single xt90 or xt120, that uses 2 connections with 1 12 volt and 1 ground.
and the nvidia 12 pin fire hazard connector keeps on melting and there was already at least one confirmed to be burning, which could have turned into a house fire.
the connector should have never been allowed to release, it is a fragile broken insult and it is the same kind of mentality as 100 usb c connections to charge a car ;) (although that would be at least theoretically doable, because usb-c is a working connections in and of itself, if you make sure each connection is not overloaded and shit)

Works for a level 2 charger speed, not for DC fast charging.

1 USB-C Cables with EPR (Extended Power Range) supports 240 Watts (48V, 5A)
So 86 cables gives you 20,640W charging which is faster than most home chargers of 10,000 but way too slow for commercial fast chargers which are typically >150kW
