NTSB rules out excess battery voltage in 787 incident

(Reuters) - The U.S. National Transportation Safety Board on Sunday ruled out excess voltage as the cause of a battery fire last month on a Boeing Co 787 Dreamliner jet operated by Japan Airlines Co (JAL) and widened its investigation to include the Arizona-based manufacturer of the battery's charger.

Last week, governments across the world grounded the Dreamliner while Boeing halted deliveries after a problem with a lithium-ion battery on a second 787 plane, flown by All Nippon Airways Co (ANA), forced the aircraft to make an emergency landing in western Japan.

"Examination of the flight recorder data from the JAL B-787 airplane indicates that the APU (auxiliary power unit) battery did not exceed its designed voltage of 32 volts," the NTSB said in a statement forwarded by a Boeing Japan representative.

On Friday, a Japanese safety official told reporters that excessive electricity may have overheated the battery in the ANA-owned Dreamliner that was forced to make the emergency landing at Japan's Takamatsu airport last week.

Reminds me of Toyota and the acceleration fiasco.
