Chris. I think the separator will be upgraded, thickened, and a better
method of perforating the film will be found. Also, I believe quality of
paste, and applicating method will be upgraded. Of course I think cylindrical
shape will be utilized, if it can be demonstrated that it will peform in a
Battery of this capacity and size.
Sorry, but that's just guesswork without any of the required science. Perhaps
ok in r&n, but tech log ?. Just because one man who has experience of the
technology for a different application says it's wrong doesn't mean that
this design is wrong. If the cells are managed properly, then there should
never be a problem. If the cell management fails, then anything might happen,
so perhaps the enclosure and cell mounting should be revised to better
account for worst case conditions. I'm not qualified to comment on that
though.
I wanted to say ceramcs will play a part, but I think that is a way off,
plus the possibility that in an explosion, ceramics will fracture and
become shrapnel.
Kevlar or carbon fibre ?. Perhaps they use that for intercell spacing
already ?. Internally, such cells can use an interplate material that's designed to
be self healing.
Hersman claims the method of certifying the technology will be examined.
New technology and new application of a sensitive technology may need a
different set of design rules to standardise usage for aviation.
For those who are not engineering bods, will try and get an image together
that describes the overall charger - bms - battery system. While the battery
enclosure layout might have been better, you can't consider such a failure
by looking at any single item in the system. You have to look at the whole
system and understand how each part interacts with another.
While we only have limited information, it should be possible to work out
how all the bits fit together, their interactions and possible failure
modes...
