I wonder if 80% cars in Malaysia are EV, how many charging dock needed in every charge station when it requires 30 min charging time for each car

We are now worry about proving enough electricity to supply data center and not taking EV into count yet

That is not the question. Imagine all existing petrol stations become EV charging stations. I would say that even if every existing pump is converted to EV charge point, it would still not enough to make EV car journey smooth enough disregarding the 30 min charge time.
