Abstract
A method and system for applying a multi-rate charge to a battery are included herein. The method includes detecting a plurality of predetermined electrical measurements and a plurality of predetermined charge currents. The method also includes detecting an electrical measurement of the battery. Additionally, the method includes selecting a charge current from the plurality of predetermined charge currents to be applied to the battery based on the electrical measurement of the battery and the plurality of predetermined electrical measurements. Furthermore, the method includes applying the charge current to the battery. The method also includes detecting a plurality of subsequent electrical measurements of the battery. In addition, the method includes applying a plurality of subsequent charge currents to the battery based on the plurality of subsequent electrical measurements of the battery and the plurality of predetermined charge currents.
