Large scale battery systems and method of assembly

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