The meltdown of the Li-ion battery on the Boeing 787 that grounded now 50 planes worldwide is turning Boeing's dreamline into a nightmare. The choice for Li-ion batteries is obvious: high energy, lightweight and quick charge/discharge make them very suitable for use in planes. The backdrop is also clear - Li-ion cells are trouble makers and we as electronic engineers know why… don't we?
If you really know why and if you have ideas or suggestions of how to get the Dreamliner's Li-ion problems solved, please tell us about it. What is a typical safety circuit you might expect? How to dimension Li-ion batteries, and more important, are Li-ion batteries really safe enough?
