Method for monitoring the residual charge of a battery

摘要

The method involves measuring current (i) values and voltage (U) values at two or more time points of a voltage response of the battery to one or more current pulses, whereby a current and voltage value pair is obtained per time point, computing a resistance difference parameter from the measured voltage/current measurement value pairs and determining the residual charge from the resistance difference parameter. AN Independent claim is also included for the following: (a) a storage battery with a measurement arrangement and a processor-controlled evaluation arrangement for implementing the inventive method.
