Abstract
The methods in this disclosure allow for the identification, selection, and arrangement of cells, blocks, and modules in large scale battery systems, such as electric vehicle battery systems. An example embodiment of the present invention allows for the identification of the cells, blocks, and modules with a unique identifier or associated parameter (e.g., internal resistance contributions or capacity). Additionally, to form a block, cells may be selected from a group of capacity-range sorting bins. Based on a parameter of the cell, a pseudo-number generator may be also be used to select cells from an available inventory of cells as maintained in a cell database based. Cells may also be placed in a block for uniform effective cell impedance and even cell aging while minimizing overall block capacity degradation caused by cycling. Block capacities may also be computed based on a known average temperature gradient during operation.
