A lithium ion battery on a Boeing 787 that overheated during an All Nippon Airways flight earlier this month experienced a sudden drop in voltage and was not overcharged as previously thought possible, Japan's transport safety agency said Wednesday.
Japan Transport Safety Board chairman Norihiro Goto told reporters the jet's data recorder showed the main battery, used to power many electrical systems on the jet, did not exceed its maximum voltage. That contradicts an earlier assertion by the agency as it investigates with the U.S. Federal Aviation Administration.
All 50 of the 787 Dreamliners that Boeing has delivered to airlines were grounded after the emergency landing by the ANA flight in western Japan on Jan. 16. Boeing has halted deliveries of new planes until it can address the electrical problems.
