摘要：A method for predicting the loading capability of an accumulator by measuringthe current I, voltage U and temperature T of the accumulator, and comparing themeasured values with the corresponding values of the response of an equivalent circuitdiagram of the accumulator, the parameters of the components of the equivalent circuitdiagram and the state variables are varied so that a match with the measured values isobtain. The loading capability is deduced from the matched parameters and statevariables determined in this way. The equivalent circuit diagram has the form -Uo-R-C-and the input voltage U′ of the equivalent circuit diagram is a voltage that is correctedwith respect to the measured battery voltage U, the correction function containing asvariables only the current I, the voltage U and the temperature T and as a nonlinear terma logarithmic dependency on I. By using the equivalent circuit diagram, the instantaneousloading capability, i.e., the response of the battery under a hypothetical load with anassumed current value I, is predicted by imposing this current value I on the equivalentcircuit diagram with the found parameters and evaluating the voltage responsecalculated.
