    I thought this info might be of interest to the crowd.

    2020 Prius Prime
    20K Km. - I don't drive much
    Displayed SOC: --% (i.e. zero remaining capacity)
    SOC as displayed by Dr. Prius - 14.5%
    Car was in 'Ready' mode.
    Battery temperature as reported by Dr. Prius: 11.5C (~53F)

    Voltage range from lowest cell to highest cell was 5 mV
    84 out of 95 cells are within 2.5 mV of each other.

    My car lives outside all year long. +30C in the summer and -30C in the winter.
