To be honest I have read it online as well. I don't know if it's true. I reckon if the battery is designed to take fast charging all the time, it should be okay. Another thing that affects batteries is weather. In colder climates like Europe you're probably okay. We have had reports of batteries losing half their capacity due to heat in Australia. Those were all Nissan Leafs, which didn't have any active cooling in place. We don't have an extensive supercharger network either. You'll probably be okay in East coast region. Forget about charging your car, in some remote areas you're probably not gonna get petrol either. You can only get diesel. Seems like EU is far ahead in EV adoption than AU.
