Most of the time if you're not at your own home you'll be on 110V chargers. To get 220V charging at someone else's you're likely either at another EV owners house who's gone through the trouble of installing a 220V port or you're lucky and they have a conveniently placed dryer in the garage you can steal 220V power from.

That’s only a warm climate thing. Plumbing (of the associated washing machine) that’s prone to freezing is unlikely to be in the garage in cooler climates.


There’s no particular reason that a dryer and washer have to go in the same room. I have my dryer in my garage, because it’s a hybrid heat-pump model that is very efficient when the garage is warmed up from the afternoon sun, but can provide its own heat in winter. It captures all the water in a tank, so doesn’t put any moisture into the room. Modern dryers are really quite neat :)

Uhhhh convenience? People prefer them right next to each other so that clothes washing isn’t a long journey. At least that’s why the plumbing and electrical/gas connections are usually built close to each other.


Serious question, do Americans use clotheslines? Our dryer is only really used for towels/sheets in wet weather.

The rotary clothesline [0] was standard in Australia and New Zealand for decades, although with the move to smaller sections, people tend to install compact linear lines instead.

Some do but it was considered a poor thing for much of the 20th century to the point where many cities and HOAs had rules against them. This is changing but it amazed me when I lived in California where in the summer you could line dry in similar times at zero cost.

Generally no. Line drying has a connotation of poverty in the US and many cities have ordinances like this that make it tough to do. Also houses being generally larger and detached in the US we have an easier time installing them compared to row houses in Europe. They're also just built more recently so they have accommodations for them built in already.

"No person shall place or allow to remain exposed to the elements laundry, clothing, rags, or other cloth items hung or stored on a front porch or front or other street yard of a dwelling."


Oh wow. I did wonder why dryers were so frequently used in the US. Don't you have to worry about it shrinking clothing though?

I haven't had much trouble with that personally. Sometimes the first wash will shrink clothes slightly but afaik a lot of clothing manufacturers these days put clothes through a 'pre-shrinking' process that compacts them down simulating the shrinking process so they won't shrink appreciably.

A bigger concern is additional wear and tear. Dryers seem to be harsh on clothing and will reduce the lifespan vs just hanging.

Unless you are not in North America. Most of the rest of the world have a base voltage of, and all domestic outlets are 220-240.

In the US "220V" refers to a high current outlet normally, in a country where household outlets are 220V, you still need a high current outlet and, for safety reasons, most outlets are not high current, just like in the US.

A 220V outlet will always give you more power for the same current limit than a 120V

A 220V outlet won't always have the same current limit though.

True, but in the US most 240v outlets are 30-50A, whereas in countries that use 240v for their normal household outlets, the current limit is usually 13-15A. Still double the wattage of a typical US outlet but not up to the standards of a “Level 2” charger.

Wait, this is terribly confusing. Why would "220 volts" not refer to a completely objective measurement of current?

The Volt is a unit of electric potential. The SI unit of current is the Ampere. You can have very large potential differences (in V) with very small current (in A). The unit of power is the Watt, and 1 W = 1 A*1 V.

So, a given power can be obtained using any voltage, with the proper current. In practice, high currents are unsafe so we tend to avoid that in unprotected sockets. Different norms correspond to different tradeoffs.


The voltage and current combined is the actually important number which is the total wattage available on that circuit. The US standard 220/240V outlet will provide ~30A of current usually while a UK outlet usually has a 13A fuse in the plug matching the circuit's rough availability.

U.K. is 220v @ 13A for an average socket. That's almost double what a common 120v 15A does in the U.S.

In the US it's 30A minimum for an average "220v" (it's actually 240 V) outlet such as a dryer or AC, that's more than double what 13A 220V gives in the UK.

You will not find a 240 in the u.s. outside of specific installations, while in the UK a common plug already is 220 13a.

It depends on what you call "specific installations", in my house I have two 240V 30A outlets for the dryer hookup and for an electric oven and one 240V 40A for the air conditioner.

We are talking of an outlet for a car in winter. It is much more common to have a common outlet outside than to have a 240v outlet. Even if there were a 240, it would be in the nema format that electric vehicles don't accept directly.

This is also the same problem with electric kettles in the U.S. they boil much faster in the u.k. because almost double the power for a common outlet.


If having 240V in an outlet was sufficient to charge a car, we could have installed a transformer and inverter in a car and charge it from a 1.5V AAA battery by pulling up the voltage to 240V. Plugging a car to a 240V outlet with a 13A breaker will only give you 2650 Watt charging power (provided there is the same code that requires 85% of maximum draw in continuous application), which is just 1 kW more than plugging into a 120V 15A outlet. Not a huge difference that would make charging bearable when the car uses more than 1.5 kW just to keep the battery warm.

An extra 1KW would actually charge the car given time. Not just keep the battery warm. 1kwh is supposedly about 4 miles. Charge for 12 hours overnight, you have enough to get to the supercharger.

In the OP story, the car was losing charge while plugged into 110V outlet, that means that 1.5 kW was not enough to keep the battery warm. An extra 1kWh might or might not get it into actually charging and even if it's been charging at 1kW it would not get 4 miles per hour, the car driving in these conditions would still use energy to keep the battery pack at the working temperature.

On a side note, I find it amusing when Brits try to brag about their superior electricity due to the progressive 240V. People living in the houses wired in a ring [1], which set themselves ablaze when they try to turn on AC, in my imagination would be more reserved ;)
