I am a little surprised that it is commonplace, but EVs are not exactly my specialist subject. Having just bought a new (petrol) car, I shall not be rushing to buy an EV, although my next car may well be one.
Well spotted, now fixed.
As I understand it 3x32A is common because it covers multiple markets - it allows single or split phase 7 kW charging (UK, USA) and 3 phase 11 kW charging (bits of Europe normally having low current three phase supplies) which are both common approaches in different parts of the world. Actual use at 22 kW is something of a bonus that drops out of that. There's at least one manufacturer who does it by having three 16A single phase chargers and using two for 7 kW single phase and three for 11 kW three phase, not giving a 22 kW mode.
