Hi,
Recent incident suggest:
1) Continued problems with battery charging "method"
2) Failure of thermal monitoring of individual cells (was implemented?)
3) Probable failure of voltage monitoring of individual cells (is implemented?)
4) Delay of monitoring.
AFAIK smoke was visible BEFORE electronic alarms.
Smoking occur after cell abuse, mostly during charging.
A decent System can ABSOLUTELY avoid cell abuse.
The BAD Thales original design seems still present. "Murphy" is around the corner.
Parallel charging was not implemented? IMHO, would be the best option MAIN/APU Li batt. for airliners.
