  • Adaptive battery charging based on battery condition
    Publication number: 20020075003
    Abstract: A test pulse having an amplitude (IP) and a duration (T) is applied to the battery. The battery voltages at the beginning (V1) and at the end (V2) of the test pulse are measured, and a difference voltage (&Dgr;V) is determined. This difference voltage is used, either alone or along with the difference voltage for a new battery and a compensation factor, to determine the state of deterioration of the battery, the charge capacity of the battery, and/or the charging rate of the battery. The state of deterioration of a battery affects its charge capacity and its ability to accept a charge. A battery is best charged when its state of deterioration is considered. The charge capacity of the battery and the charging rate for charging the battery are therefore adjusted with respect to those parameters for a new battery based upon the state of deterioration of the battery.
