Is it really, have they made is more complicated than it would be if properly engineered. Wireless or wired does not add a lot to the code or computing requirements but of course the quantity does make demands but still these tasks are not that complicated. monitoring tens of thousands if voltages and temperatures and controlling tens of thousands of switches. is child's play, computer code wise. Granted at these quantities it does match ICE engine control computer power requirements, but the code is not sophisticated just the volume of data is bigger. A couple simple algorithms run simultaneously or sequentially for thousands of channels. I am not expecting the sample rate needs to be that high. Even fast charging is a slow process.
