Some recent posts on Reddit give us some news that might look bad on the surface but really show us something good. It turns out that GM’s battery software errs far on the side of caution for Bolts and Bolt EUVs after the fire recall.
Even the best manufacturing lines still spit out a few defects, though. The new Bolt battery packs haven’t had any widespread problems, but it’s not safe to assume that the improved cells will always be perfect. So, it’s informative to learn about the first faulty battery we know of post-recall., service personnel disconnected the 12-volt battery. The local technician looked at the battery and determined that a new pack was likely needed, but then something more unusual happened.
As part of that past recall, the company first tried to avoid replacing all batteries by developing a battery monitoring program. Without needing to add any new hardware, they found a way for the battery management system and the vehicle’s computer to work together to watch for unusual voltages and perhaps other electrical readings .
