摘要： Determination of an electric vehicle battery state-of-charge (SOC) based on measuring open circuit voltage is subject to error as the relationship changes over time. A method is provided for updating the relationship during aging. A charging current is applied to the battery cell. A favorable charging condition is detected in response to a predetermined charging current. A charging slope vector is compiled during the charging condition comprising a plurality of slope values over respective state-of-charge increments. A plurality of SOC-OCV slope vectors are determined corresponding to a plurality of stored SOC-OCV aging curves, each SOC-OCV slope vector comprising a plurality of slope values over equivalent state-of-charge increments. One of the stored SOC-OCV aging curves is selected having an SOC-OCV slope vector best fitting the charging slope vector for use in converting measured OCV values to battery cell SOC values.

摘要： A system using a computer to be configured to perform particular actions by virtue of having software, firmware, hardware, or a combination installed. One aspect includes a system, programmed to receive a fault signal from an auxiliary battery sensor. The system also determines if a low voltage set point is greater than the main battery voltage, and sends an open switch signal to a battery isolation switch if the low voltage set point is greater than the main battery voltage value. The system will send an auxiliary set point signal to an auxiliary battery charger to maintain a low voltage. The system will receive a current signal from an auxiliary battery sensor to indicate an auxiliary battery current value. The system also determines if the auxiliary battery current is above a maximum current value, and send a disable auxiliary battery maintenance signal to the auxiliary battery charger.
