Abstract: A method for inhibiting whisker growth on a metallic substrate susceptible to whisker growth (e.g., tin, zinc, cadmium, indium, silver, lead, aluminum, gold, aluminum, gold, and alloys thereof), the method comprising coating a surface of the metallic substrate with a charge dissipative (CD) polymer, or more particularly, an electrostatically dissipative (ESD) polymer, that inhibits whisker growth on said surface under conditions where whisker growth would otherwise occur. In some embodiments, the CD or ESD polymer does not possess the necessary strength and/or thickness to function as a physical barrier for whisker growth. In particular embodiments, the CD or ESD polymer prevents the onset of whisker formation or growth, thus not requiring the CD or ESD polymer to function as a physical barrier.

Abstract: A method and system to determine if there is an open cell in a battery pack of cells arranged in a lattice. Voltage measurements from each parallel cell group along with information on the battery pack topology are used to estimate the resistance of each cell group. The resistance of each cell group is calculated based on the measured voltage less a nominal open circuit voltage divided by the current level of the battery pack. The average cell group resistance of the battery pack is also calculated. The cell group resistances are analyzed statistically using the resistance of each cell group and the average cell group resistance to reveal outliers which are indicative of open cell groups.
