Abstract
Described is an apparatus for extending cycle-life of a battery cell, where the apparatus comprises: a monitor to monitor a rate of degradation of a battery cell overtime; a comparator to compare the rate of degradation with a threshold; and logic to adjust one or more charge parameters of the battery cell when the rate of degradation crosses the threshold. Described is a method which comprises: monitoring a rate of degradation of a battery cell overtime; comparing the rate of degradation with a threshold; and adjusting one or more charge parameters of the battery cell when the rate of degradation crosses the threshold. Described is a machine-readable storage media having machine executable instructions stored thereon that, when executed, causes one or more processors to perform the method described above.
Claims20
A machine-readable storage media having machine executable instructions stored thereon that, when executed, causes a processor to perform a method, the method comprising:
- monitoring a rate of degradation of a battery cell overtime, wherein the rate of degradation is a ratio of a difference in capacity of the battery cell to a difference in number of charge/discharge cycles;
- comparing the rate of degradation with a threshold;
- and
- adjusting one or more charge parameters of the battery cell when the rate of degradation crosses the threshold, wherein the adjusting of the one or more charge parameters is to slow the rate of degradation of the battery cell to extend cycle life of the battery cell.
An apparatus comprising:
- a monitor to monitor a rate of degradation of a battery cell overtime, wherein the rate of degradation is a ratio of a difference in capacity of the battery cell to a difference in number of charge/discharge cycles;
- a comparator to compare the rate of degradation with a threshold;
- and
- logic to adjust one or more charge parameters of the battery cell when the rate of degradation crosses the threshold, wherein the logic is to adjust of the one or more charge parameters to slow the rate of degradation of the battery cell to extend cycle life of the battery cell.
A system comprising:
- a memory;
- a processor coupled to the memory;
- a battery to provide power to the memory and the processor, the battery having circuitry including:
- a comparator to compare a rate of degradation with a threshold, wherein the rate of degradation is a ratio of a difference in capacity of the battery cell to a difference in number of charge/discharge cycles;
- and
- logic to adjust one or more charge parameters of the battery when the rate of degradation crosses the threshold, wherein the logic is to adjust of the one or more charge parameters to slow the rate of degradation of the battery cell to extend cycle life of the battery cell;
- and
- a wireless interface to allow the processor to communicate with another device.
