Abstract
A method for predicting the internal resistance of an energy storage battery in assumed environmental and battery state conditions includes subdividing the internal resistance into a first resistance component which represents the electrical resistance of the energy storage battery for the region of electron conduction and a second resistance component which represents the electrical resistance of the energy storage battery for the region of ion conduction. The method also includes determining the first and second resistance components to be expected for the assumed environmental and battery state conditions. Each of the first and second resistance components are determined as a function of parameters of the assumed environmental and battery state conditions. Monitoring devices or computer programs may be utilized to carry out the method.
