Not a practical idea
Now i just buy my new car my battery have 100% health with excellent autonomy range i go i swap the battery with one maybe 80% health with not the same autonomy range or i want to sell my new car but with the old battery that i get from the swap 😵💫
What is the charge rate, and how long does it take for a swap station to recharge a depleted battery? Entering a busy time period, say a swap station has 10 batteries fully charged. The first 10 customers in line wait to swap. How long did the 11th through 20th customers have to wait? Peak demand is "normal" and requires more information to be published and shared.
Swapping batteries makes sense to dynamically exchange among longer range and shorter range packs to save weight. Swapping is desirable to upgrade to newer technologies with higher power density, lengthen mean-time-to-failure, or right-to-repair aging batteries.
