Abstract
An apparatus and method for charging a battery with an improved charging performance and a reduced degradation of the battery. A battery charging profile is configured to achieve a minimal degradation of a selected battery possible for a given charge time. A minimization is achieved using battery degradation modeling data indicative of a battery degradation level of a selected battery, and voltage and temperature response modeling data indicative of a predicted battery voltage and a predicted battery temperature of the selected battery as a function of time and charging current.
