You don't need 22kW charger if your car has 50kWh battery. Those cars usually have 11 kW on-board AC charger anyway. In fact, for daily driving, 3 kW overnight charging at your home should be plenty - you would be able to charge up 30 kWh in 10 hours. 22 kW chargers are for cars with ludicrously large battery, like Tesla Model X which has 100 kWh battery.
