I didn't see any mention of whether the battery management needs to be altered or if that's something that came with the package. It's exciting since my Prius has 183 thousand miles on the clock and I've been getting 35mpg due to the cold... I'm prepared to replace the traction battery if needed but if I can upgrade instead that'll be great. I was thinking that one could buy a Prius Prime traction battery and swap it into an older Prius but that's not cheap and I have no idea whether it bolts in or not. Apparently all Primes shipped with Li-Ion which handles plugin charging better or something? I don't know.
