Investigation into Boeing 787 battery problems moves to maker of monitoring system
TOKYO – The joint U.S. and Japanese investigation into the Boeing 787's battery problems has shifted from the battery-maker to the manufacturer of a monitoring system. (www.foxnews.com) More...

I've designed fuel cell monitor systems for the Space Shuttle Program in the 90's for a major telemetry company. If design haven't changed since, the data acquisition / monitoring system acquires the measurements from all sensors and then converts them into a data stream for analysis basically. So yes generally it sits there and collects data.
Unless the journalists are reporting it wrong, monitoring systems do not control the charge or vary it based on temperature. The charging system does these. So, does the monitoring system feed signals to the charging system or does it sit there and simply report on what it measures? Both over and undercharging can cause problems with this battery technology. My bet would be a faulty charging system with insufficient temperature sensors and cell measurement points. Anyone want to start a pool on this?
I concur with your assessment, and I like keeping my money. The fact that it is taking so long to determine a cause is in the methods of attacking the problem. The FAA doesn't want to leave any stone unturned, and that is understandable. However, at some point they must define what is causing the problem and work towards a solution. If they don't then Boeing will be facing bankruptcy very soon.
The investigation into the incidents is in the hands of the NTSB, not the FAA. However if the FAA deems 'problem solved', they have the power to do so. But given all the agencies involved, I think FAA will hold on jumping the gun.
Getting it right the first time trumps any financial consideration when it comes to safety.

Apparently the great Boeing , with all their resources, has more trouble getting things right than the tiny company that makes the kit for my 1130 lb homemade experimental airplane. The penny pitchers at "Boing" should have known that companies who can't convert from metric to inch/foot can't get it right.
Who would even post a link to Faux News, come on we don't need sensationalist journalism here!
