SAE International Design Considerations when Disproportionate Heating of Lithium-ion Battery Packs is Present 2008-01-2865

This paper summarizes a series of papers investigating the, in use, behavior of lithium-ion cells and packs. Initial efforts concentrated on cell data 2x and were reported in 2003 through 2006. Follow-on efforts concentrated on battery pack data 2x and were reported in 2007 through 2008. In these efforts lithium-ion cells and batteries (4P4S, 2P4S and 4S) were cycled at various conditions. Battery packs, fully augmented with control and monitoring electronics, were subjected to an external heat source at varying intensities which were applied to the base of the battery during both charge and discharge. This heat source effectively heated one cell of the battery string.
