NTSB announces dates and agenda for lithium ion battery forum

Today the National Transportation Safety Board announced that its upcoming forum, "Lithium Ion Batteries in Transportation," will be held on April 11-12. The NTSB also released a preliminary agenda for the event.

The NTSB announced on March 7 (when it released its interim factual report on the Jan. 7 Japan Airlines Boeing 787 battery fire investigation) that it would be holding a forum to better understand how lithium ion batteries are used across transportation modes.

MHI er involvert i et energi-prosjekt (forskning/kvalifikasjon) i Orkenöyene hvor 2000 heavy duty Lithium-ion batterier (Maker : kanskje Yuasa ?) bygges inn samlet i en 20' container til opplagring/distribusjon mellom höy- og lav-bruksperioder i 24t av elektrisk energi produsert med vindmöller.

Synligvis menes det at BMS/BCU kan holde alle evntle 'thermal runaways' i sjakk ? Totalt anvendes TO slike containere som tilsammen inneholder 2000 x 2 = 4000 Lithium-ion batterier. Good Luck med prosjektet, MHI !

Sitat fra artikkelen : "FAA’s approval of lithium batteries for other passenger models made by Boeing and Airbus may have been based on those same tests and should be reviewed, the NTSB said yesterday in recommendations to aviation regulators.

“Researchers have found that current test methods might not reliably produce failure” in the way that occurred last year when batteries on two Dreamliners began chain reactions producing fire-like heat and fumes, the NTSB said.

The safety board makes suggestions for improvements without the regulatory power to implement them. If its recommendations prompt the FAA to change how it approves lithium-ion batteries, manufacturers may need to retest systems that have been in service for years, and future designs may become more expensive.
 
Så FAA hade 90 dager på seg å svare på Dette. Blir vel noen mindre modifiksjoner i framtiden for Dreamlinern
 
Ser ut som en 787 fra United nylig opplevde et batteri som ble overopphetet, men at sikkerhetsmekanismen tydeligvis funker

A United Airlines Boeing 787 experienced a lithium-ion battery failure on approach to Charles de Gaulle Airport on November 13. United Flight 915 was at the end of a seven-hour flight from Washington's Dulles Airport when pilots received a warning that the main battery was overheating. United spokesman Charles Hobart confirmed the event, which was first reported by the Aviation Herald.
