Why can’t electric cars be self-charging?
However, because a large portion of the kinetic energy is lost as heat, the recovered energy will be significantly lower than the expended energy, so the hopeful thought that electric cars charge while driving is not possible. There are currently no self-charging car technologies available. When your electric car runs out of charge, your engine will die and you’re going nowhere fast. Pull over to the side of the road to a safe, flat spot (one that’s preferably free from sand and mud) and park.
