摘要：A method for determining a status of a vehicle battery includes determining aninitial temperature and an initial state of charge of the battery, determining a currentthreshold value based on the initial temperature and the initial state of charge of thebattery, starting the vehicle engine, charging the battery for a predetermined chargingperiod t, measuring two charging currents, Iand I, to the battery at two predeterminedpoints in time during the charging period t, determining an expected current value at atime t=t+tbased on the measured charging currents, comparing the expected currentvalue with the current threshold value, and determining the battery is faulty if theexpected current value is lower than the current threshold value.
