METHOD AND APPARATUS FOR DETERMINING THE STATUS OF A BATTERY IN A VEHICLE |
摘要 |
A method for determining a status of a battery in a vehicle, the method comprising; determining an initial temperature and an initial state of charge of the battery; controlling that the initial state of charge, SoC, does not exceed a predetermined threshold value and that the initial temperature, T, is not below a predetermined threshold value; determining a current threshold value based on the initial temperature and the initial state of charge of the battery; starting an engine of the vehicle; charging the battery for a predetermined charging period t 1 ; measuring two charging currents I 1 and I 2 to the battery at two predetermined points in time during the charging period t 1 ; based on the measured charging currents, determining an expected current value at a time t 3 = t 1 +t 2 ; comparing the expected current value with the current threshold value; and if the expected current value is lower than the current threshold value, determining that the battery is faulty. |
