1. A method for charging a battery, comprising:

  • obtaining a set of charging currents {I1, . . . , In} and a set of charging voltages {V1, . . . , Vn}; and

    repeating constant-current and constant-voltage charging operations, starting with i=1 and incrementing i with every repetition, until a termination condition is reached, wherein the constant-current and constant-voltage charging operations include,charging the battery using a constant current Ii until a cell voltage of the battery reaches Vi, and thencharging the battery using a constant voltage Vi until a charging current is less than or equal to Ii+1.
