TonyIndo, it's quite clear that you're a Fortescue Fanboi...
The reason Fortescue bought WAE was mainly for its battery management technology, which is essentially algorithms coded into software. This is often protected by copyright, and not patents for obvious reasons. It's also very difficult to protect/moat, and it's quite easy to overtake if you have a company like Tesla to put its effort to it. We're almost two years into the acquisition of WAE, and it's not clear that Fortescue's backing has moved the needle on WAE's original financial performance.
One thing Fortescue, particularly Andrew Forrest, hasn't learned is that technology isn't like iron ore. To built FMG, Andrew could throw his weight around and be a bit fast and loose. Nobody can take your assets off of you, and you just need a few core steel mill customers who don't care how you run your business. However, in technology, your nemesis/competitor is also your customer.
Why would anybody want to go into business with Fortescue or depend on Fortescue for their revenue?

Mac4218, it's likely the BMS would be licensed under a software package - or similar to software as a service. It's unlikely to be protected by patents because even if it was patentable, that would need to be disclosed and worldwide protection/defence is expensive and limited in its protection cf copyright.

FAnotTA, Hertz moved away from Teslas because the cost of running them was high because there are very limited spare parts, and Teslas are often expensive to fix if they're pranged. That was in their press release.
