    I'm wondering if there is a chart showing max charge rate and if it has temperature offsets.
    I'm also wondering if the P100 charges at higher KW than others due to more cells? P60vs90 etc.

    It was cold out and I was only one at the station.
    50% started at 48KW and it climbed to 72KW by 65% but then dropped to 69kw at 70%

    That sounds like the charge was temperature limited at first. The charge rate went up as the battery warmed up, but then you hit the taper limits around 70%.

    The max charge power is about the same for all cars except the smaller batteries - original 60, possibly the 70 & 75 - and the infamous "A" version of 85.
    All else being optimal (especially temperature) the larger batteries will have a less aggressive taper until closer to full, so will effectively accept a higher charge rate.
    BTW there is no P60.
