    摘要： An embodiment contemplates a method for estimating a capacity of a battery. A state of charge is determined at a first instant of time and at a second instant of time. A difference in the state of charge is determined between the first instant of time and the second instant of time. A net coulomb flow is calculated between the first instant of time and the second instant of time. The battery capacity is determined as a function of the change in the state of charge and the net coulomb flow.

    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.

    摘要： A method for estimating vehicle battery parameters that uses two different sampling rates. The method samples a battery terminal voltage and current at a high sampling rate to estimate the battery open circuit voltage and high frequency resistance. The battery state of charge (SOC) is derived from the open circuit voltage. Next, the battery terminal voltage and current are re-sampled at a low sampling rate. Other battery parameters can be extracted from the low-rate sampled signals. Next, all of the battery parameters that were obtained from the two sampling rates are used together to predict battery power.
