CHICAGO, Wed Feb 20, 2013 — Boeing Co. has found a way to fix battery problems with its grounded 787 Dreamliner jets which involves increasing the space between cells, a source familiar with the U.S. company’s plans told Reuters.
“The gaps between cells will be bigger. I think that’s why there was overheating,” said the source, who declined to be identified because the plans are private.
The 50 Dreamliners in commercial service were grounded worldwide last month after a series of battery-related incidents including a fire on board a parked plane in the United States and an in-flight problem on another jet in Japan. Until the Dreamliner is cleared to fly again, Boeing will be starved of delivery payments.
The logical solution for Boeing would be to install ceramic plates between each cell and add a vent to the battery box, Kiyoshi Kanamura, a professor at Tokyo Metropolitan University who has conducted research with several Japanese battery makers, told Reuters on Tuesday.
Earlier on Wednesday, the chairman of state-run Air India said Boeing is hopeful of getting the Dreamliner back in service by early April.
