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.

BYD's megawatt charging breakthrough proves that the range wars are alive and well, but also relies quite a bit on infrastructure.
