摘要： A system and method for estimating internal parameters of a lithium-ion battery to provide a reliable battery state-of-charge estimate. The method uses a two RC-pair equivalent battery circuit model to estimate the battery parameters, including a battery open circuit voltage, an ohmic resistance, a double layer capacitance, a charge transfer resistance, a diffusion resistance and a diffusion capacitance. The method further uses the equivalent circuit model to provide a difference equation from which the battery parameters are adapted, and calculates the battery parameters from the difference equation.

摘要： A battery state-of-charge (SOC) estimator uses a robust H∞ filter design by taking into account the battery parameter uncertainties, which is due to battery age, variation, and operating conditions such as temperature and SOC level. Each of the time-varying battery parameter values and their variation rates are bounded. By utilizing the parameter variation bounds and parameter variation rate bounds into the design process and minimizing the H∞ gain from the measured current signal to the estimation error of Voc, the battery SOC estimator can achieve enhanced robustness to the variations of battery age, variation, and operating conditions that include temperature and SOC level.

摘要： A system and method for determining whether an onboard estimation process, such as a recursive least squares regression process, can effectively calculate the state-of-charge of a battery. The method includes defining a current sample time and a previous sample time and measuring the battery current. The method then calculates a variation moving average of the measured current and an index of current change rate determined by averaging the absolute value of the current variation moving average using the measured current and calculated moving averages from the previous sample time. The method then determines if the current change index is greater than a predetermined threshold, and if so, the estimate of the battery state-of-charge resulting from the onboard estimation process is valid.
