Fast charging is viable, but experts say building the actual charging stations will be the tricky—and potentially very expensive—part.

China is back with another engineering marvel. This time, in the form of BYD’s new battery system which is reportedly capable of charging an electric car in just five minutes – roughly the same amount of time as refueling a combustion vehicle.

China's BYD has unveiled a megawatt charging system that it says can charge an EV as quickly as filling up a fuel tank, and said it will build a network across China, igniting a new super charging race.
