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.

Large scale battery systems and method of assembly

In one embodiment, a process may be performed in parallel on a parallel server by defining a data type that may be used to reference data stored on the parallel server and overloading a previously-defined operation, such that when the overloaded operation is called, a command is sent to the parallel server to manipulate the data stored on the parallel server. In some embodiments, the previously-defined operation that is overloaded may be an operation of an operating system. Further, in some embodiments, when the data stored on the parallel server is no longer needed, a command may be sent to the parallel server to reallocate the memory used to store the data.
