The 150k miles of driving is nonsense.
The MG ZS EV has 68kWh usable battery. CO2 emissions for manufacturing that battery would range between 2000 kg and 13,600 kg depending where the battery is manufactured. (It’s roughly 30kg to 150kg CO2 produced per kWh of battery size.)
A typical fossil powered car emits around 1000 kg of CO2 in 2,500 miles of driving.
So best case is 5,000 miles of driving, worse case is 34,000 miles of driving depending on where the battery is manufactured.
And note that while that mileage is being driven the car is producing no emissions.
