Abstract:
1. A method for charging a series battery, comprising: charging the series battery, wherein the series battery includes a set of banks which are connected in series, so that the same charging current passes through each bank in the set of banks; measuring a voltage across each bank in the set of banks as the series battery is charging; for each bank in the set of banks, comparing the measured voltage for the bank with a target voltage for the bank, wherein comparing the measured voltage with the target voltage comprises computing a difference between the measured voltage and the target voltage to produce a set of differences for the set of banks; and adjusting the charging process based on results of the comparisons between the measured voltage and the target voltage for each bank by limiting a voltage output for the charging process based on a result of a comparison of the differences in the set of differences.
