摘要：
Some embodiments of the present invention provide a system that charges a battery. During operation, the system obtains a set of charging currents {I1, . . . , In} and a set of charging voltages {V1, . . . , Vn}. Next, the system repeats constant-current and constant-voltage charging operations, starting with i=1 and incrementing i with every repetition, until a termination condition is reached. These constant-current and constant-voltage charging operations involve charging the battery using a constant current Ii until a cell voltage of the battery reaches Vi, and then charging the battery using a constant voltage Vi until a charging current is less than or equal to Ii+1.
