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?

Batteries are big and expensive, so it makes a battery swap station big and expensive. In addition they are all custom battery packs, so when going for a battery swap, you’d need to do it at a station that has your specific battery on hand.
Imagine if cell phones were like that, I have a Galaxy S7, I have to go to an S7 charge station, can’t use an iPhone charge station, can’t even use a S6 charge station. And then when my phone is too old, the charge stations will probably stop carrying my battery. So really, logistically, it’s a complete nightmare to do it.
Current batteries charge in 30-45 minutes, 10 minute charging is not too far off. And really, like your cell phone, how often do you really need to get it charged in 10 minutes? 95% of the time you plug it in when you go to bed, and it lasts as long as you stay awake. That other 5% of the time, you can take 15 minutes to charge it, and get an extra half charge, which will probably extend you as much as you need for the day.
