Chinese automaker BYD continues to leave Tesla in the dust. The company introduced a new battery system on Monday that it claims can charge an electric vehicle in just five minutes, about the same time it takes to refuel a traditional car.

Elon Musk’s politicking damages his electric vehicle brand, but the underlying problem is its relatively old line-up of models, even as Chinese competitors change the game.
