Supercharging

How Much Cell Imbalance Is Normal? 263 Days of Pack Data, and Why Regen Looks Worse Than a Supercharge

On 16 September my own monitoring flagged my own car’s battery pack.

It was wrong. Worse, when I went looking for the culprit I found the wrong one — I assumed the supercharge that afternoon had done it, and the data says the drive home was twice as bad.

Both of those are worth showing, because the mistake underneath them is the same one that makes owners panic at a cell-imbalance number read off an OBD app.
