Battery data and what to do with it

[thenaimis]

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).

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.

That was pack voltage?! I always thought that was voltage coming into the car. (face palm)

Charging voltage at a supercharger is slightly higher than pack voltage.

Gotcha... so pack voltage is just a guesstimate less that what appears on the screen?
