Default Re: Nissan Leaf Over Voltage

Interesting... So your saying that the actual readings from the cells match what the monitor is telling you?

If that is the case it would seem only one of the two voltage sampling chips was effected, or somehow just the cells that are terminated to the first sample chip (00 - 08 ) were effected.

The "contractor" you dropped something on, is that the contactor you are using for HV/LV cutoff or the drive system solenoid/contactor? Or are you utilizing relays for your HV/LV cutoff?

Seems weird to me that not all of your cells were affected by the situation. I'm wondering if it would be a good idea to disconnect the pack, and possibly disconnect all the cells from each other to try and make sure there is no further damage to the cells not effected?

Either way, that is not a good scenario for those cells, if they truly read the 6v+. In theory, I believe, those cells have irreversible damage... I'm not an expert when it comes to this, so wait for one to chime in on this point.
