The reports are consistent with the EA cabs doing something that are causing the packs to blow their pyrofuses. The only thing that really makes sense is some kind of transient DC overvoltage. The problem with pyrofuses is that they are slow. They will stop some kind of catastrophic event like a battery fire, but they are too slow to prevent damage.

Having seen inside their cabinets, I wouldn't plug into one if you paid me. Building a reliable charging network is apparently only a secondary business goal of Electrify America.

Hah, yeah the EA cabinets are a bit messy inside compared to the superchargers [0]. Smells like they were rushing to get an MVP out without spending too much, probably many more COTS components in there and not as much thought put into harness routing and custom assemblies. I know EA sources chargers from multiple manufacturers; maybe some of them are better in this regard.
