Abstract

A system for monitoring a plurality of cells in at least one battery, the system comprising: means for obtaining a plurality of measurements of a parameter at a plurality of times tl to tn for each of a plurality of cells in a battery; means for ranking the plurality of cells in dependence upon the plurality of measurements of the parameter taken at each of the times tl to tn to obtain a ranking value for each of the cells at the times tl to tn; and means for causing storage of the plurality of ranking values.
