Same Yuasa brand, same issue with a single cell causing the problem, as was the case in the two Boeing 787 incidents, but a different flavor of Li-Ion chemistry. It will be interesting to see if the focus (finally) goes inside the cells themselves, instead of addressing peripheral, unlikely, easier to protect against, and easier-to-check-and-rule-out causes.
As appealing as Li-Ion batteries are, this thermal runaway seems to have been such a common problem that one would think the root causes by now would have been discovered and remedied?
Two days ago, I read an article (Discovery News) about an emerging affordable 1,000 mile aluminum-air batteries for cars. They would be a game changer if they really could be deployed. Will Lithium-Ion batteries prove too hard to control - or are we just not yet at the point of having all the necessary process controls on their production?
I don't know much about the technology behind these batteries so I'm wondering how they still missed the fact they were building a battery that could fail when surely the best minds in the lithium-ion battery business did all the testing they could possibly come up with? I hope the battery issue have already been addressed. I truly hope the battery problems have been fixed. One can only imagine what would happen if something even remotely similar would happen again.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
