  • Apparatus for determining the state of physical properties of rechargeable electric energy storage devices
    Patent number: 5349540
    Abstract: A process for determination of the state of physical properties of recharble electric energy storage device. Process input values of the energy storage device are measured and processed in a computer, in accordance with a predetermined model in the form of closed linear or non-linear multiparametric functions or a heuristic prametering process to generate derived values for physical properties, which are compared with the measured process input values, and the model or estimation is modified for the succeeding measurement.
