Why can’t we keep battery stock at charging stations and replace the batteries in the car instead of waiting for the battery to charge? It would be much faster and many electric bikes and skateboards have this opportunity. I can understand that the current structure of the car might not allow but why is it not possible or if it is possible what is the issue being faced?
In: Engineering
It would be possible, but EV batteries are much larger and heavier than bike or skateboard batteries. Because of size and weight, you’d need some pretty sturdy materials to fixate the battery on the car. This requires extra tools and takes time. Also, the car design would become far more difficult. In most cars that were actually designed as EV, the battery is spread out over the entire bottom of the car. This improves handling and stability. A replacable battery would have to be much more concentrated.
All that would only save you a few minutes of time too, as most recent EVs and chargers can get you a few 100 miles of range in 20-30 minutes and this technology is still improving. So while it’d be possible (and has been experimented with, I believe), it’s just nog worth it.
