AnswerDo I need a 7kW EV charger?
For most homes, yes — 7 kW is the standard on a single-phase supply and fully charges most EVs overnight. 22 kW needs a three-phase supply few homes have.
In more detail
A 3-pin plug (2.3 kW) works in a pinch but is slow; a dedicated 7 kW unit is safer and far faster.
