This is one of those places where we need regulators so step up I think. The Nissan Leaf has been so thoroughly reverse engineered that people can transplant almost all of its components into another Leaf or even an ICE car. However, there are so many cars coming out (particularly from startups with manufacturing in China) at the moment that it could quickly overwhelm the efforts of the limited number of car hackers to keep up. There should be a reasonable path to detailed specifications if / when manufacturers no longer are willing to supply a replacement battery.
