Abstract: Electrical interconnection architectures for electrically connecting stacked prismatic battery modules in various combinations of parallel and series configurations that distribute heat sources (e.g., heat conduction through a busbar, and internal resistance heating from short circuiting) to multiple battery cells, rather than to a single adjacent cell, thereby reducing thermal excursion propagation. Examples of interconnection architectures include various combinations of overlap bus and bypass bus configurations. A two-parallel module configuration may have two serial sub-modules with cells connected in a staggered interconnection pattern. A busbar connection pattern may allow the negative inlet and positive outlet to be located on the same end of a battery module. Battery cells may be interconnected so that a parallel cell is not an adjacent cell. Various combinations of resistors and fuses may also be used to reduce overheating from short circuiting.

Abstract: The present disclosure teaches prismatic battery modules having prismatic repeating battery sub-units with alternating pairs of a high Energy Density (HED) battery cell stacked next to a low Energy Density (LED) battery cell. A ratio of the high energy density divided by the low energy density may be greater than 1.3. Additionally, a thermal barrier may be placed in-between adjacent HED and LED battery cells. Optionally, a LED battery cell may serve as a thermal damper when placed in-between adjacent HED and LED battery cells, thereby reducing the total number of thermal barriers needed. High voltage HED and LED electrical buses may be placed in offset positions according to each HED or LED cell type, so that both types of high voltage electrical buses may be located on a same side of each battery module.
