1. A method comprising:

  • connecting a power supply to a battery;

    generating a pulse train comprising a plurality of pulses;

    producing a pulsed charging current from the power supply by modulating the power supply with the pulse train, the battery thereby being charged by the pulsed charging current;

    simultaneous with charging the battery with the pulsed charging current, making a plurality of measurements of current or voltage, or both current and voltage, of the battery; and

    varying the pulsed charging current as the battery is being charged based on the plurality of measurements, including varying pulse lengths of the pulses that comprise the pulse train or pulse durations of the pulses that comprise the pulse train, or both the pulse lengths and the pulse durations of the pulses that comprise the pulse train.
