Hi,
cwatters:
approach minimum voltage too frequently the MTBF reduces dramatically?
Teething phase of batteries in a new aircraft
Uncharted waters.
FlightPathOBN:
"Aggressive" marketing specs.: 150 A compared to 16 A of competition.
Where is this page? Source?
I did a quick Google translate on the JTB report..
The overall flavor of all of the slides was they were not able to re-create the failure mechanism, and are going to do much more testing and analysis, including electron scan microscope, further research, and will set up a testing and evaluation methodology in the future...
Confirming my concerns
On Voltages recorded THERE IS A PROBLEM:
If the negative tip of the remaining cells were not SAFELY connected to ground, (AS HAPPENED) the voltage WILL BE LOWER. Will post the equivalent circuit on that problem ASAP.
Fact is:
DFDR is not capable (as configured in 787) to show VALUABLE and NECESSARY information on how battery failed. IMO in teething phase of an a/c, complimentary means should be required for.
