why not just have the battery on rails (ala power tools), use a forklift or similar tool with a fitting to relese the "battery catches" slide the battery back, pickup new pack, slide into pusition, catches engage, at worst, sill cover to hide the battery pack.....
If someone can design a power tool that can survive the "tender mercies" of the average contractor / builder for a substantial time then its surely not impossible to do the same for a car battery pack?
Just smells like CBA more than not possible
Biting the hand that feeds IT
