The drive data logged by PriiDash includes the HV battery current, and the voltages and resistances of individual modules. We can use the data to check the health of the HV battery pack. Here is an example from the data shared by Glenn Blanc. First we look at the current to see if the battery is exercised enough to give meaningful result. We want some large charging and discharging currents that's close to 100A, not all tiny small currents. Here we do see a good current range: Now we can look at the distribution of the voltages and resistances of individual modules to see if any module deviates from the population. The voltages: The resistances: They all look good, no significant outlier module that I can see. Good result!
