  • Battery charger and method
    Patent number: 8569999
    Abstract: The present invention relates to a method for compensating for temperature effects in a pulsed battery-charging scheme with an average charging current less than the root-mean-square (rms) current. The method comprises varying the ratio of the average charging current to rms current as a function of the battery ambient temperature. The method may also comprise varying an upper threshold charging voltage as a function of the battery ambient temperature. The invention also relates to a battery charger.
