Claim 0:
1. A method for matching cells, comprising:
conducting an impedance measurement on each of a plurality of cells prior to assembling said plurality of cells into one or more cell modules, said impedance measurement including a stimulus signal including a plurality of frequencies;
concurrently measuring said plurality of frequencies within one period of a lowest frequency of said plurality of frequencies;
generating an impedance spectrum of said impedance measurement on each of said plurality of cells;
comparing spectrum characteristics in said impedance spectrum of said impedance measurement between said plurality of cells; and
grouping said plurality cells into a plurality of cell groups, said cells within each of said plurality of cell groups having said spectrum characteristics included within a threshold range of said spectrum characteristics.
