Abstract

A process is disclosed for evaluating the remaining charge in an accumulator battery by determining the residual charge at the start of discharge, adding up the quantities of energy extracted as and when the battery is used, determining the quantities of charge which are not restorable instantaneously because of a high discharge rate, charge which is restorable by relaxation of the battery and charge which is not restorable under the influence of temperature.
