چکیده

This paper proposes an adaptive method to balance cell voltages in alternating battery cell method. In the alternating battery cell discharg cells are periodically discharged in turn. Recovery effect increases battery output voltage while the given battery cell rests without discharging, thus battery operation time of targe However, voltage mismatch between cells leads voltage difference between cells induces inter-cell current with wasted power. Second, it degrades battery operation tim when any cell reaches to the minimum system operation voltage. solve this problem, the proposed method adaptively discharge time to equalize both cell voltages. In the proposed method, battery operation time increases about 19%, while cell discharging method shows about 7% improvement. Keywords—Battery, Recovery Effect, Low Battery Cell Discharging, Adaptive Discharge Time

Battery Operation Time Enhancement Based On Alternating Battery Cell Discharge

This paper proposes an alternating discharge method of multiple battery cells to extend battery operation time. In the proposed method, two battery cells are periodically connected in turn to a mobile device and only one cell supply power while the other rests. Battery operation time of the connecting cell decreases due to rate-capacity effect, while that of the resting cell increases due to re...
