Abstract
The present inventions, in one aspect, are directed to techniques and/or circuitry to applying a charge pulse to the terminals of the battery during a charging operation, measure a plurality of voltages of the battery which are in response to the first charge pulse, determine a charge pulse voltage (CPV) of the battery, wherein the charge pulse voltage is a peak voltage which is in response to the first charge pulse, determine whether the CPV of the battery is within a predetermined range or greater than a predetermined upper limit value and adapt one or more characteristics of a charge packet if the CPV is outside the predetermined range or is greater than a predetermined upper limit value.
