Charge electric car from dryer plug?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of using a standard 220V dryer plug to charge electric vehicles, exploring the implications for residential charging infrastructure, safety concerns, and practical challenges associated with such an approach.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express surprise that quick chargers require separate power lines, questioning why existing 220V dryer plugs cannot be utilized for charging electric vehicles.
  • One participant provides calculations indicating that charging times from a standard outlet would be significantly longer compared to a dedicated circuit, raising concerns about practicality for daily use.
  • Another participant suggests that while charging from a dryer plug may not provide fast charging, it could be a simple solution for overnight charging when circuit capacity is available.
  • Concerns are raised about safety, particularly regarding the potential for overheating and the risk of using inadequate extension cords for high currents.
  • Some participants argue that logistical issues, such as the inconvenience of dragging long cables from the dryer to the vehicle, could deter users from this approach.
  • There is mention of the need for heavier cables to withstand wear and tear if used frequently, as well as the potential for increased demand on residential electrical systems when multiple high-draw devices are in use simultaneously.
  • One participant notes that the demand for fast charging is primarily for commercial operations, suggesting that residential charging needs may differ.

Areas of Agreement / Disagreement

Participants generally agree that using a dryer plug for charging is theoretically possible, but there are significant concerns regarding safety, practicality, and the capacity of residential electrical systems. Multiple competing views remain regarding the feasibility and desirability of this approach.

Contextual Notes

Limitations include assumptions about the availability of circuit capacity, the safety of using existing plugs, and the potential for increased electrical load on residential systems. The discussion does not resolve these issues.

what can we infer about people from oregon and jersy?

hhmmmm...

They have elected representatives who are both concerned for their welfare and aware of the dangers of volatile hydrocarbons?

I think it would be wise to stop here.

elected officials with concern?
isn't that like military intellegence?

lol (and no offence ment to anyone)

Actually, it was our idea.

wiki on filling stations said:
In 1982, Oregon voters rejected a ballot measure sponsored by the service station owners, which would have legalized self-service gas.

It never stops raining here you know.

Plus, it keeps our 18 year olds busy.

Having used self service only for decades in the UK, it was refreshing to be served at the pumps by someone in the 'backwoods' of New Hampshire, recently. Where would the movies have been without all those scenes where the couple drive into the gas station and we wonder whether the attendant will spot that they're escaped villains as he cleans their windshield - then he gets shot and they drive off leaving the hose spraying petrol all over the forecourt. I bet the 'officials' didn't think of that scenario in their zeal for safety! That wouldn't happen in self service.
I also got to use a non-automatic pump for the first time in 45 years of driving. I stood like a lemon until I realized you have to move the lever over durrr.
