Electric vehicles: a new challenge

Electric vehicles: a new challenge

EV charging has become a central theme.

Initially the idea was to enjoy the night/dawn when usually cars are stopped at home. On off-peak hours. Thus the charge would be in many hours impacting little on the demand of the house.

But in real life users are demanding for "fast charge". That lasts minutes and not hours.

And so an important challenge arose. It is a matter of enabling "large" power chargers, which therefore need to be connected at medium voltage and requiring the associated transformers. These are significant investments that need to be amortized.

In this scenario there are two cost items:  demand and energy. Demand to amortize the investments and Energy for the commodity. Otherwise it is not feasible. As simple as that!

Hi Amal, regulations in each country determine the answer to your questions. It might be the local power distributiuon company and/or private enterprises. But at the end of the day, the final cost of the ownership needs to be paid!
