Elon Musk Offers Boeing SpaceX Batteries For the 787 Dreamliner

An anonymous reader writes "Boeing is currently dealing with a bit of a disaster as the company's 787 Dreamliner has been grounded due to safety concerns. Boeing is currently investigating the situation, but they aren't alone. Elon Musk, CEO of Tesla Motors and SpaceX, has stepped in to offer his help and technology if Boeing wants it. Musk has had to harness battery tech not only to run his Tesla Motors, but also to function flawlessly aboard SpaceX spacecraft as they travel both in and out of the Earth's atmosphere. If you need a battery to work at any altitude, you'd trust Musk to supply one, and that's exactly what he's offering Boeing."

      More importantly, the SpaceX design is for batteries that are actually used, and not a backup-on-backup. Tesla/SpaceX has an interesting design (series connection of highly parallel set of cells, with active heating/cooling), but it isn't what Boeing actually seems to need. I wish more details about the Boeing (Thales/GS Yuasa/Securaplane) design does for its battery management system were available. I would have thought that the system does very frequent sweeps of cell impedance across a range of frequencies to proactively detect a failing cell and isolate the battery, but that doesn't seem to be the case.

      Honestly though, the 787's battery problems look fairly overstated. The ANA problem on the ground seems to indicate that some level of monitoring and active ventilation is required when the plane is not pressurized, and the JAL incident seems to be a failed battery and a mild over-reaction by the pilot given the ANA incident. There are a few system improvements that should be made to containment and venting from what I can tell... but nothing too major.

      I wonder if boeing buys from aircraft spruce and specialty like everyone else? And yes aircraftspruce.com does sell different chemistries for aviation lithium systems. Probably due to quantity Boeing goes direct to mfgr.

      They'd be infinitely more likely to go with a COTS LiFe system than jury rig somebodies Li-Ion car or rocket battery into place.

      Lithium ION can be made to blow up and you can only put those on a plane if is a LSA, ultralight, experimental... or maybe Boeing. Can anyone confirm the actually battery chemistry? There's about a zillion different Li chemistries all with different issues. Lithium IRON phosphate is FAA / DOT / whatever approved and theoretically electrochemically impossible to blow up, and only a bit heavier. If Boeing actually managed to set a LiFe battery on fire thats gotta be the first deployed LiFe fire I've ever heard of, they're supposed to be heavy but indestructible. I know several general aviation planes have LiFe batteries having seen them with my own eyes. I don't know what the A+P mechanics had to do, I'm told modern Rotax charging systems are drop in compatible, donno about random 40 year old electrical charging systems for example. Worst case, new alternator maybe?

      I'm not a pilot or A+P but I wanted to be one once, and I've got lots of pilot friends, so this is all hearsay, but at least semi-informed hearsay. There are lots of LiFe GA planes flying around and lots of Li-Ion LSA/ultralights flying around.

      The lithium battery is supplied from the Japanese company GS Yuasa. This company was chosen by Thales (the 787 subcontractor chosen by Boeing for the Electrical Power Conversion System). FWIW, this has been in the news lately as the stock of this company rose shortly after it was announced that the battery wasn't likely defective.

      You can read all about it on their website...

      I'm an EE, but not a battery expert, but a quick glance indicates this is a fairly vanilla Lithium Cobalt Oxide Cathode technology which is the most common (probably similar to the chemistry used in your laptop or cell phone battery). Also, by all accounts these folks seem to be a competent battery supplier (they've apparently flown batteries in satellites and got a contract for the international space station).

    As noted the issue was not the batteries, which have passed muster after inspection by the FAA and the NTSB - the focus now is on the charging systems and monitoring systems, as well as the related failure of the containment system.

    SpaceX may have a fantastic battery, but they still need to use a charging system designed for charging from a power source that is fairly unreliable in consistency (the four generators on the 787s engines, and the generator on the APU), a power source that is reliable but completely different in power characteristics (ground power), and be FAA certified. Not to mention that it needs to be charged and discharged on a much regular basis than that of a battery used on a booster.

    I rather think SpaceX's solution to the charging system is not compatible with that required by regular service usage of the Boeing 787.

      Here's the thing... These batteries should have on-board controllers, with temperature and physical deformation sensors on each cell.

      Any sort of over-voltage, current over-draw, overheating, or cell bulging should trigger a temporary disconnect.

      It should be literally impossible to damage the battery, no matter what the airplane systems attempt to do to it. That is obviously not the case if they are relying on circuits external to the battery for safety.

      Umm, what? The batteries DO have "on-board" controllers--how much more on-board can you get than putting them in the same box? It's not like you can fuse protection circuits into the lithium cells themselves, and a properly designed BMS supporting multiple cells is no different than strapping individual BMS's on each cell, and likely weighs less. It *should* be impossible to damage the battery, but it obviously *wasn't*, so now they have to take apart the box to see which part failed.

      Like I said, "protected" cells are nothing more than an "unprotected" cell in a box with a protection circuit . There is nothing magical about them, and nothing inherently better about them besides the reduced possibility for assembly error.

      Per-cell protection circuits become impossible when the pack voltage and/or current exceeds that which can be safely switched by small semiconductors or self-resetting thermal (PTC) fuses. Plus, per-cell protection circuits can malfunction just as easily as per-pack circuits, and can be harder to diagnose and repair. So claiming that Boeing's problems would be magically fixed by "protected" cells ignores the constraints imposed by their design requirements.

      More likely then you might think. I work in the aviation industry and crap like that is what you have to deal with once you become an international organization. We (the engineers) just learned recently that India has put in place regulations that if you want to sell planes in that market (which is a huge market) you have to use India-based work for a minimum of 20% of the development/manufacturing effort spread across all parts of the project. Which is why we now have an India-based office who gets to play in all sorts of projects... and which we have to cleanup after in all sorts of projects.
