Maybe I'm missing something, but it's hard for me to imagine >anyone< succesfully patenting series-parallel connection of multiple cells. That art is as "prior" as it gets! Even if you consider the use of a BMS, it's essentially the same design as laptop computer batteries, just on a much larger scale, no? But many other elements go into a successful, reliable EV battery design. For example, I think Tesla has a method for bypassing or disabling failing cells (correct me if that's wrong). If they developed it, surely they filed for a patent. There are probably many other details of the Tesla battery design that are patented.
