    This paper is prepared for battery cell manufacturers who want to optimize battery pack fuel gauging in light of uncertain user patterns and less-than-ideal cell behavior outside of the laboratory. The idea of coulomb-counting the gain or loss of energy to and from the battery pack is a popular and low-cost method. This technique finds use in nickel-metal hydride (Ni-MH), nickel-cadmium (NiCd), se... View full abstract»

    The performance of a secondary battery is affected by the ionic resistance of the separator used to separate the anode from the cathode. If the ionic resistance is too high, the power output from the battery is diminished because the flow of ions is hindered. This paper examines issues that affect the ionic resistance of regenerated cellulose membranes. In particular, changes in the pore size, or ... View full abstract»

    Charge algorithms for Li-ion batteries require that charging current stop once a maximum voltage threshold is reached. Each battery in a Li-ion pack must be individually monitored for this condition, so charging of the entire pack ceases as soon as one cell reaches this voltage limitation. Cell balancing algorithms seek to remove charge from the offending cell to equalize voltage and enable additi... View full abstract»
