As I've had my second-gen 3.0 battery for a few months now, I'm noticing some differences from the original pack. The weather was hot over the weekend so I wanted to perform a cooldown charge after a long drive. The pack was about 34C. I started the charge session at 16A and switched it to range mode to get the AC to kick on and cool things down. The car charged OK but the AC would not start. I know it was working because I had been using it to cool the cabin throughout the drive, and there were no error messages. Every 10 - 15 minutes I would switch back to std mode for 2 - 3 minutes before reverting to range mode. The AC would not kick on. Eventually I raised the charging rate to 24A which caused the pack to heat up to 36C, and low and behold the AC came on and cooled it down to about 34C. It never came on again before the charge finished at 35C despite having it in range mode for most of the session.
I can only wonder if the newer version of the 3.0 packs have a higher thermal tolerance and the firmware has been updated to allow higher temps before calling for cooling. This may be true for all 3.0 packs but I haven't heard anyone mention it over the last 6 years. Has anyone else noticed this or is it unique to my car?
