Yep, I misunderstood what was being said. The charge screen, both in-car and on-app show charger input voltage and current, but not battery. Probably not useful for double-checking battery V/A.Unless you can get into the Diagnostics screens, the car will not report pack voltages while charging from an AC connection. Only DC fast charging from a supercharger or Chademo charger shows pack voltage, and only on older firmware (anything prior to FW8.0).
