  • Measuring battery degradation
    Patent number: 10162401
    Abstract: Approaches and related devices monitor the condition of a battery via voltage measurement during routine recharging instances. An approach includes supplying a charging current to the battery during each of a plurality of routine charging instances. The charging current is increased by a measured or predetermined amount during a current pulse portion of each of the routine charging instances. A resulting change in a battery voltage of the battery during the current pulse portion of each of the routine charging instances is measured. An impedance-indicative value of the battery is determined for each of the routine charging instances based on the change in the battery voltage during the current pulse portion. The impedance-indicative value is stored in a memory device for each of the routine charging instances. A condition of the battery is estimated based on one or more changes in the impedance-indicative values.
