Comment on Americans’ junk-filled garages are hurting EV adoption, study says

Stupid article. You don’t need 240 V , you can charge with a regular wall plug. For a lot of usage patterns this is more than enough.

You can make it work on 120V, it just uses ~20-30% more energy due to the overhead of running all the vehicle systems for so much longer while charging.

I think that number is a bit off. Yes, there is overhead when charging a car to run its battery management system, heat losses in the wiring, etc. But it’s not 20-30% of the ~kilowatt of power you’d run through level 1. A quick search says that 20% loss is at the higher end for level 1 (probably 15% on the lower end) but even level 2 has about a 10% loss.
The bigger issue is that level 1 just doesn’t have nearly as much power as level 2. Most cars charge at level 1 at 8-16 amps. Most level 2 setups charge at a few times that, plus the voltage is doubled so the total power ends up being about 10x as much. But that’s not to say everyone needs that power either. Honestly, for the average driver it’s quite easy to make level 1 work.

No, that number corresponds to the WiFi you need to connect it to, to send all the telemetry and the LLM that will be running on some server in the US, picking data out of your telemetry and deciding which company to sell it to, while your car is powered.

Do you really think that or are you looking for an opportunity to make a statement?
