Hi,

There is a major difference in the 787 electric architeture in respect to the batteries.
In ANA case i would expect:
1) A battery fault warning indicating a failure.
2) A second one indicating battery temperature.
3) A third possible indicating smoke in EEbay
Interestingly to mention DC bus certainly NEVER SUFFERED any influence. (the battery is always OFFLINE if gennies (redundant) are working normally.
The approach to keep the battery "disconnected" brings advantages.
