Abstract
In an exemplary embodiment, a method of charging a battery includes supplying a charging current to the battery and measuring one or more battery parameters. The battery parameters may be, for example, temperature, voltage and/or charging current. The battery parameter measured is used to determine a charging current set point. The set point may be selected from a number of different set points stored in memory, where each set point corresponds to a respective battery parameter range. If the charging current being supplied to the battery is different from the charging current set point determined the charging current is adjusted to match the set point. This process is repeated for each of a plurality of time periods (e.g., sampling periods) during charging of the battery.
