Reuters - Most Boeing Dreamliners grounded for battery checks
I wondered when the FUD tie-ins to EVs would happen...
AP - Lithium batteries central to Boeing 787 woes
This quote from Dr. Czysz is a cheap shot. Yes, Li-ions require special handling, and Boeing needs to figure out what's going on here, but I highly doubt these aircraft battery issues were caused by a battery coolant leak, and they certainly weren't the result of crash-testing. Separate issues.The 787 is the first airliner to make extensive use of lithium-ion batteries to help power its energy-hungry electrical systems. The batteries charge faster and can be better molded to space-saving shapes compared with other airplane batteries.
"Unfortunately, what Boeing did to save weight is use the same batteries that are in the electric cars, and they are running into the same problems with the 787 as the problems that have shown up in electric cars," said Paul Czysz, professor emeritus of aeronautical engineering at St. Louis University.
The lithium-ion batteries in several Chevrolet Volts used for crash-testing caught fire in 2011. General Motors engineers eventually figured out that the fires were the result of a battery coolant leak that caused electrical shorts after side-impact crash tests. GM retrofitted the car with more steel to protect the battery. No fires were ever reported on real-world roads.
