While I agree that having a charging point at home is not mandatory, it's much much friendlier,

Even a normal outlet can handle slow charging an EV if you drive less than 100km a day.

Typical EV usage : 18kWh per 100km

Typical "granny" charger : 1800 watts (240v,7 amps)

10 hours at 1800 watts = 18kWh = 100km.

Get home at 6pm, plug in car, car is charged at 4am , leave for work at 7am. Enough spare time there to shift to charging outside peak evening usage at 9pm instead.

Here in the US typical outlets are 120v 15A max. Sure thats also 1800 watts but for a margin of safety, typically, appliances won't use anything over 1500 watts, or about twelve and a half amps.

[–] Nollij@sopuli.xyz 1 points 5 hours ago

It's 12 amps even. It's the 80% rule for continuous draw, defined as expected use to run for 3 hours or more. That's why a space heater is 1500 watts, but a hairdryer is 1800.

Oopse. Good catch. Will edit. Missed the "0" lol

[–] Mihies@programming.dev 1 points 9 hours ago

Yes, exactly. But if you live in an apartment, you don't have even such outlet.
