DEVICE AND METHOD FOR DETERMINING A STATE PARAMETER OF A BATTERY
摘要
The invention relates to a device (100) for determining a state parameter (122) of a battery, comprising a voltage detector (110) and a processor (120). The voltage detector (110) measures a terminal voltage (Umess) of the battery. The processor (120) calculates a plurality of current samples based on a plurality of known samples (102) of an earlier probability distribution of a state indicator of the battery and a plurality of error probability samples of an error probability distribution. Moreover, the processor (120) determines a plurality of weighting factors for the plurality of current samples based on the plurality of current samples and the measured terminal voltage (Umess, SOC, DeltaSOC). The processor (120) further calculates the state parameter (122) of the battery based on the plurality of current samples and the plurality of weighting factors.
