Abstract:
1. A method to adaptively charge a battery, wherein the battery includes at least two terminals, the method comprising: applying a charge signal to the terminals of the battery, wherein the charge signal includes a plurality of charge packets, wherein a first charge packet includes a first charge pulse; measuring a plurality of terminal voltages which are in response to the first charge pulse, wherein each terminal voltage is a voltage between the terminals of the battery; determining a first charge pulse voltage (first CPV) of the battery, wherein the first CPV is a peak voltage which is in response to the first charge pulse; determining whether the first CPV of the battery is within a predetermined range or greater than a predetermined upper limit value, wherein the predetermined range and/or the predetermined upper limit value changes during charging of the battery in accordance with changes in a state of charge of the battery; and adapting one or more characteristics of a second charge packet of the charge signal which temporally follows the first charge packet if the first CPV of the battery is outside the predetermined range or is greater than a predetermined upper limit value.
