Publication number: 20160139210Abstract: A method and corresponding device, for monitoring a charge of a battery. The method obtains a battery current measurement value and a battery voltage measurement value, and applies a current integration method to update a primary charge estimate value representative of the charge stored in the battery by taking into account the battery current measurement value. The method further determines an ancillary charge estimate value representative of the charge stored in the battery using a battery model taking into account the battery voltage measurement value, and determines an error value for the ancillary charge estimate value, in which the error value expresses the reliability of the battery model. The method also applies a correction to the primary charge estimate value as function of the ancillary charge estimate value and the error value. Interpretation of the correction applied in this manner allows determination of current sensor offset and battery capacity change.Type: ApplicationFiled: June 18, 2014Publication date: May 19, 2016Applicant: VLAAMSE INSTELLING VOOR TECHNOLOGISCH ONDERZOEK NV (VITO NV)Inventor: Peter COENEN
