GS Yuasa working closely with Boeing to get 787s flying again: chief


The president of Kyoto-based GS Yuasa Corp., the maker of lithium-ion batteries for Boeing Co.’s troubled 787 Dreamliner, said Monday that it is working with the plane maker to get the high-tech jetliners back in the sky as soon as possible.

In his first statement over the Dreamliner trouble, Makoto Yoda said, “We are sharing information and collaborating with Boeing” and other parties as well as the Japanese and U.S. authorities.

With Boeing 787s grounded around the world following a January emergency landing by an All Nippon Airways Co. Dreamliner experiencing smoke in its cockpit from an apparent battery fire, Yoda said, “Going forward, we will continue to work closely with Boeing to enable the resumption of its jetliner operations as soon as possible.”

The statement came after a report last week that Boeing and GS Yuasa “are at odds over what should be included in the final package of fixes intended to get the jets back in the air” and which prompted the battery maker to stress the cooperative structure between the two firms, according to a company official.

“GS Yuasa development, design, production and quality teams are tirelessly applying their knowledge and engineering expertise 24 hours a day to ascertain the causes of the problems and improve the safety of the batteries,” the battery maker said.

    Mr. Yoda has very kindly expressed a difference of opinion with Boeing; his batteries are of such high quality that they are approved for use on the International Space Station.
    Boeing oves an apology to Japan; Mr. Yoda did not raise public issue with the unfair attempts to blame GS Yuasa, but knowledgeable sources and investigators understand that he graciously allowed Boeing to save face.

    Sometimes, American business makes the mistake of confusing politeness for a lack of stregth. As an American, many of us are upset that the real story remains untold, but the truth is slowly emerging. The question now is whether the CAB will allow Boeing to escape scrutiny for deceiving many in their attempts to hide flaws and blame others.

    Press reports indicate that YUASA batteries were selected for use by Pratt and Whitney for components of the International Space Station planned for 2017. The environment for batteries in the ISS is not necessarily one that is harsher than that of the 787. Passenger aircraft go through repeated temperature and pressure changes plus the shock of landing and air turbulence. Other press reports have described YUASA as a relatively minor producer and have claimed that its lithium ion battery production has been unprofitable. While a major supplier of lead acid batteries for use in cars, trucks, and motorcycles, YUASA has virtually no presence as a supplier of lithium ion batteries for electric and hybrid vehicles. While there may be nothing wrong with the YUASA batteries in the 787, their PLANNED used in the ISS is no guarantee of this.
