Hydrogen vs. Battery Electric Cars

Physics Girl I love your videos. This series is really fun. I have a question that I was hoping you might have an answer for. With the technology we have today it seems it would be really simple to make battery electric vehicles that would have a quick swap battery. You could pull into the "refueling station" and a robot or a person with a machine could swap your depleted battery for a freshly charged one.  It would reduce the refueling time of BEV vehicles and perhaps reduce the weight of the batteries if they could be smaller and you could swap batteries more often. Why didn't this idea catch on?
