Again, the problem for many of the former EV owners who switched back to gas wasn't the lack of super-chargers. The problem seemed to be people who hoped they could recharge their car overnight or while at work (a natural expectation) but found that their available charging options couldn't provide enough power even over a longer time frame.
Out of curiosity, what amperage, wattage, etc. are we talking about here, for a level 2 charger? I can get 240 volts easily enough, but I'd probably have to run a charger from my shop, whose 100 amp service is not under constant stress. The 100 amp at the house is minimal, resulting in things like the lights blinking when the pump or the furnace comes on.
I wonder if it might be practical/useful to change building codes to require all new homes to have garages prewired for 220v. (Not necessarily to have a charger preinstalled but set up so one can be put in without any major rewiring.) Or is that even necessary?
Yeah, that's just a wee bit hefty for a 100 amp service, I think, but might be possible when the shop is not being used. Pretty close to popping the main breaker, though.
It's already pretty much how things are anyway. Power is delivered to every Americanadian house's or business's breaker box at 240V (often misnamed as 220), and home breaker boxes tend to be in the garages. The only reason most of the building is then wired for 120 (often misnamed as 110) is that the voltage is split in half at the breaker box. The unsplit original can then also be run on separate cables from the breaker box to certain points for more demanding equipment (central AC, clothes drier, water heater, oven/stove).
Since nobody would try both at the same time anyway (and the consequences of trying would only be a flipped switch even if they did), an auto-switching system isn't even need. All it would take is a socket adapter or extension chord with at least two sockets on it.
Maybe its just a local thing, but my home (and any home that I've been in) has their breaker box in the basement instead of the garage. So, there is a certain distance between the breaker box and where you would need to put a charging outlet.
Umm... why not? People would likely want to plug their cars in when they first get home (so they don't forget), and they may want to do laundry in the evenings. (That's when I generally do it myself.)
Personally, I would find that... extremely annoying. I suspect in my case I would end up with a lot of dead car batteries and wet laundry, since I suspect I would probably forget to flip the switch on my car after the laundry was done.
From what I understand, the standard voltage in North America used to be 100V, but it was eventually changed to 110v (in order to make light bulbs brighter). It was later increased to 120v.
A good plan, and there's no real problem putting in another 240 volt outlet, but the dryer line is only 30 amps. Not enough to exploit the full potential of the charger without heating up the wires and risking burning down the house.
