Why does 110 charge the car at 3mph, but 220 charge at 35mph? It’s 2x volts but >10x charge speed.
In: Physics
I’m not sure how you’re getting from volts to speed. But I can explain a bit about electricity. The amount of power being put into something is related to both current and voltage: Power=Volts x Current. When you double the voltage, it also doubles the current, so you get 4x the power from 2x the voltage.
So at the same higher voltage circuits tend to be able to handle much more power. Chances are that the charging on 110v is limited by the house’s circuit limit. The 220V circuit is most likely sized to handle a lot more power going through it.
