Claim Text:
1. A method to charge a battery during a charging cycle having a plurality of portions, the method comprising: setting a first charge-time parameter for a first portion of the charging cycle, wherein a charge-time parameter of a portion of the charging cycle comprises a time to reach (i) a state of charge of the battery or (ii) a charge storage level corresponding to usage time of the battery; generating a first charge signal during the first portion of the charging cycle, wherein one or more characteristics of the first charge signal are calculated to charge the battery as required by the first charge-time parameter during the first portion of the charging cycle; applying the first charge signal to the battery during the first portion of the charging cycle; setting a second charge-time parameter for a second portion of the charging cycle; generating a second charge signal during the second portion of the charging cycle, wherein one or more characteristics of the second charge signal are calculated to charge the battery as required by the second charge-time parameter during the second portion of the charging cycle; applying the second charge signal to the battery during the second portion of the charging cycle; calculating feedback data including one or more of: adapting one or more characteristics of the first and/or second charge signals based on the feedback data by changing the first and/or second charge signals during the first and/or second portions of the charging cycle.
