      Controlling powerful battery's volatility poses urgent design challenge for Boeing
      You might like to read the article .
      Until now , Boeing has remain unequivocal over the question of adopting or even studying different battery technology, saying simply: "We have no such plans at this time."

      If you read it , you might just find out the truth of the matter , the problem is not a problem from 3000 miles away , the problem is an in house problem .

        Everett, or Seattle.  Boeing moved their HQ to Chicago, somethig about lower costs, I'm sure.  More likely there wasn't any more money to squeeze out of Washington, Seattle, Everett, Renton, Kent, Auburn...........

              SEATTLE, Jan. 24, 2013 PRNewswire -- Boeing (NYSE: BA) welcomes the progress being made in the 787 investigation discussed today by the U.S. National Transportation Safety Board (NTSB) in Washington, D.C. The regulatory and investigative agencies in the U.S. and Japan have dedicated substantial resources to these investigations, and we appreciate their effort and leadership.
              Funny this says Seattle and not Chicago .

              If you do a google map search for 100 N Riverside Plaza, Chicago, IL 60606 , you will see what looks to my eye to be a building for bean counters .
              I bet the team that does the design engineering isn't in Chicago . But they might be , who knows .

                Typically the first word the publicist places on the form is the city they want it to originate from.  I would suspect that corporate is trying to distance themselves from the damage they caused.

                As I design engineer, I know that the design team does not get to make sourcing decisions of this magnitude, they're made by the bean counters.  Not just the fabrication / assembly work was outsourced, the bidders were required to provide design work for their sub-assembly.  So while there may have been standards and requirements set forth, it doesn't appear that there was an effective mechanism for enforcing compliance in place.

                Management always sees joint development projects as a way to save development costs.  They think that they will be able to bring a new product to market for half the cost.  Yet, every joint development I've been on has cost more than doing it in house.  There is so much 'forming, storming and norming" that no one gets the chance to perform.

                    You go and find that someone makes the same mistake you have and you feel that proves you correct ?

                    Have you read the Av week yet ? It really does tell the story of the problem very well .
                    Do you understand why the question was asked if they were thinking about getting rid of the "Li-ion" ?
                    You could hear about the problems from people who understand , or you could go on as you are .

                    So while there may have been standards and requirements set forth, it doesn't appear that there was an effective mechanism for enforcing compliance in place.
                    "may have been" ? "it doesn't appear" ? "Bingo" ?
                    Its not a problem of "enforcing compliance" of "standards and requirements set forth" .
                    That is not what is going on .
                    Boeing said lets go with large li-ion batteries , batteries that are known to be unsafe , batteries that have been tried and rejected in other aircraft , batteries that have been replaced in other aircraft when these very same problems happened .

                    Do you know at what temperature the li-ion battery melts and goes on fire ? Do you know the same for nickle ?
                    Do you know what thermal runaway is ?
                    http://en.wikipedia.org/...

                    Especially prone to thermal runaway are lithium-ion batteries.

                    As of January 8th 2008 the TSA (transportation security authority) has some new restriction on transport of lithium batteries on aircraft. Basically they don't want large lithium batteries carried on aircraft because of the (remote, but real) possibility that they may catch fire. They REALLY don't want them in checked baggage and they don't want too many in carry-on luggage.

                    More on Lithium Batteries

                    The term "lithium battery" may refer to a lithium ion battery, lithium metal battery, or a lithium polymer battery. Lithium polymer batteries are a kind of lithium ion battery. Lithium ion batteries re rechargeable lithium batteries, like the ones found in cameras, cell phones, laptop computers, and radio-controlled toys. While smaller lithium ion batteries are allowed on aircraft, larger ones containing more than 25 grams Equivalent Lithium Content (ELC) are not. An indirect measure of ELC is watt-hours, with eight grams ELC being equal to about 100 watt-hours. If you are not sure of your battery's ELC or watt-hour measurement, or if your kind of battery is allowed on the flight, check with your airline or with the manufacturer of your battery.

                    Another kind of lithium battery that is banned from airliners are lithium metal batteries with more than two grams of lithium. The lithium metal batteries commonly used by consumers usually don't have this much lithium, but if you are unsure you should check.

                    http://www.wired.com/...
                    The lithium-ion batteries used in the 787 are relatively new batteries made of relatively large cells compared to those used in most consumer devices. The history of lithium-ion batteries has many thinking the problem might not be a “teething problem” with the airplane, but instead an issue with the batteries.

                    Unlike the well-proven, and relatively small bundles of battery cells used in consumer devices or even the Tesla electric car known as “18650s,” the batteries in the 787 made by GS Yuasa of Japan are produced in low numbers and are not used in many applications. And as the focus on the battery continues, one lithium-ion expert says the large batteries used by Boeing simply increase the potential for failure.

                    http://www.technologyreview.com/...
                    The U.S. National Transportation Safety Board chairman, Deborah Hersman, said yesterday that the battery that recently caught fire on a Boeing 787 Dreamliner in Boston showed signs of short circuiting and a phenomenon called thermal runaway.

                    The specific lithium ion battery chemistry used in the airplane—lithium cobalt oxide—is particularly prone to thermal runaway, in which heat in a battery triggers more heating until it catches fire (see “Grounded Boeing 787 Dreamliners Use Batteries Prone to Overheating”). Thermal runaway can be triggered by a short circuit between the electrodes in a battery. The NTSB said that it is not clear why safeguards put into place to stop thermal runaway didn’t work.

                    http://www.technologyreview.com/...
                    Because the electrolyte materials used are flammable, no lithium-ion batteries are completely safe. Some companies are developing a version that doesn’t use these electrolytes (see “Solid-State Batteries”). Consequently, battery makers install various safety features, including electronics designed to prevent overcharging. They also often include sensors and cooling systems.

                    According to GS Yuasa, its battery for the 787 “comes with battery management electronics which guarantees multiple levels of safety features.” A specification sheet for the batteries warns, “Inappropriate handling or application of the cells can result in reduced cell life and performance, electrolyte leakage, high cell temperatures, and even the possibility of smoke generation and fire.”

                    Boeing declined to comment on its selection of battery chemistries.

                    http://www.nytimes.com/...

                    In what would seem to be the worst possible outcome right now, Boeing might also have to redesign its powerful new lithium-ion battery system, or even switch back to older, safer models. Aviation experts said such changes could cost hundreds of millions of dollars and shave off some of the 20 percent savings in fuel costs that the new jets have delivered.
                    One risk for Boeing is that adjustments in the lithium-ion batteries could require changes in other electrical equipment. But the biggest risk is that the batteries could prove too volatile, and Boeing would have to redesign its systems to use heavier and less-efficient nickel-cadmium batteries.
                    The F.A.A. set a series of conditions in 2007 to ensure that the 787’s batteries did not overheat or spew flammable materials. It was reviewing whether the company had properly taken those steps.

                  I know that the design team does not get to make sourcing decisions of this magnitude, they're made by the bean counters.
                  Do you think the bean counters said lets do "Li-ion" ? Do you think the bean counters overruled the engineers on the " Li-ion" issue ?

                  As a design engineer would you have ever said yes to a bean counter saying to put a "Li-ion" battery pack in when you know the history of "Li-ion" battery on aircraft ?

                  As I design engineer, I know that the design team does not get to make sourcing decisions of this magnitude, they're made by the bean counters.  Not just the fabrication / assembly work was outsourced, the bidders were required to provide design work for their sub-assembly.  So while there may have been standards and requirements set forth, it doesn't appear that there was an effective mechanism for enforcing compliance in place.
                  You still don't get it , its not a matter of outsourcing . Nobody outside Boeing said to Boeing that they had to use "Li-ion" batteries . That was a design engineering problem .
                  I would suspect that corporate is trying to distance themselves from the damage they caused.
                  You point a finger at corp when you must know that the design engineers did the design work .
                  Management always sees joint development projects as a way to save development costs.
                  This isn't a joint development problem .

                  Boeing screwed up , they failed , they failed to spec out the batteries to be not "Li-ion" , they failed to notice the problems before they handed over the aircraft .

                  Typically the first word the publicist places on the form is the city they want it to originate from.

          They were either moving to Denver, Chicago or, i think, one of the Texas cities, mainly because their executives were tired of flying four hours to DC and wanted to be in better proximity to all their plants and offices.
