Quick answer
The MG ZS EV takes approximately 10 h 15 min to fully charge (0-100%) on a Public AC 22 kW charger, limited to 7.4 kW by the car's onboard charger. That gives you about 36 km of range per hour of charging.

Charging at Public AC 22 kW
Public AC 22 kW chargers use a three-phase connection at 32A per phase. They are less common than 11 kW chargers but can be found at some public charging locations and workplace installations.
Important: The MG ZS EV's onboard charger is limited to 7.4 kW (1-phase), so it cannot use the full 22 kW. The effective charging power is 7.4 kW, and the charging time is the same as at an 7.4 kW charger. This is a common source of confusion. The charger may show 22 kW available, but your car will only draw what its onboard charger supports.
Whether a 22 kW charger is worth seeking out depends on your car. If your car's onboard charger tops out at 11 kW, a 22 kW charger offers no speed benefit. Check your car's specs before assuming faster AC charging.
