Technical concern
Hi,
Thinking on how different is the application of these (suposed) "proven" cells on the new design of 787 and:
1) The low MTTR
2) The "diode scheme"
3) The DC generation from redundant sources
4) The higher electric energy use for more functions
5) The ripple naturally present in busses
6) The Boeing selection of this battery
7) The offering of just une option: Li Ion
How is done the filtering of the busses? There are capacitors banks along the busses? Or any "sudden drop" of voltage makes the battery supply the energy (through the hi speed switch - the diode). If there are spikes (sudden negative going voltage levels) in the busses the battery is not as "offline" as previously thought.
OTOH we may imagine most high power loads (that required the 1.45 MW generation capability) are AC driven.
