RR_NDB:
Fwics, to get the best result, each cell should be monitored for voltage and
temperature, with the sensors and ic in a single package that could be
built in to the cell during manufacture. Then, a simple serial protocol gets
the data back to the individual cell charging circuits. For any new technology
that has serious safety implications, it should be if anything overengineered
to start with, while experience is gained out in the field. Would assume that
Boeing have done something like that.
TURIN:
Square wave suggests that it's coming from inverters, not from an alternator, but
perhaps it makes sense as it's easier to rectify that to provide dc for the subsequent
motor inverters, or any other load that that needs dc voltage. Someone mentioned
1.4Mw capabilty onboard. Serious amount of power and wonder what they use
all that energy for...
