Yes, but it it does if I'd like to get a 22kW charger installed, right?
A 22kW EVSE does require 3 phase - however there are very few vehicles which can use it.
Most vehicles only have an onboard single phase charger, so even if you have a 3 phase EVSE installed, the car will only use one of those phases.
EVSE = the device on the wall which supplies AC electricity to the vehicle. Often called a 'charger' but it's really just a box with some relays inside to switch the electricity on and off, some also have other features to indicate to the car how much power is available to be used.
The actual battery charger is inside the vehicle, and that's what determines how many phases can be used, converts AC to DC, monitors the battery and so on.
Even if you obtain a vehicle which can use 3 phase, it's mostly pointless.
For charging at home, you plug it in when you get home, and then when you go back to the car hours later or the next day, it's charged.
How fast it is and how long it actually takes is irrelevant.
Even in the case where it's not 100% charged when you return to the car, it's also irrelevant because it's rarely necessary or desirable to charge an EV to 100%
Electric vehicles are not petrol, and they are not refuelled in the same way.
Petrol cars are driven around until there is no fuel left, and then it's drive to a special fuel place to pour petrol into it until full.
EVs are charged when parked, which is the vast majority of the time. How 'full' the battery is when it's plugged in to charge is irrelevant. So is how 'full' the battery is when you use the car again.
The exception is for long journeys of 100s of miles, where it makes sense to charge to 100% at home immediately before starting that journey because home charging will be much cheaper than public charging.
However that is not the majority of journeys. Most people do not drive 100s of miles every day or even every week.
