Abstract
A method for charging a battery comprises: measuring a battery voltage with a voltage sensor and a battery current with a current sensor; applying, with a charging circuit, a first charging current to the battery until the measured battery voltage exceeds a predetermined voltage threshold, a magnitude of the first charging current being held at a first constant value; applying, with the charging circuit, in response to the measured battery voltage exceeding the predetermined voltage threshold, a second charging current to the battery until a cutoff criterion is satisfied, a magnitude of the second charging current being such that the battery voltage exceeds a steady state voltage limit for the battery; after the cutoff criterion is satisfied, determining a rest voltage of the battery; and updating the cutoff criterion based on a difference between the determined rest voltage and a target rest voltage.
