Abstract: A method and apparatus for fast charging a battery with optimal charging. In an arrangement, a system includes a battery charger for applying a voltage to a rechargeable battery; and a controller coupled to the battery charger and monitoring at least one of a battery voltage, a battery temperature, and the current flowing into the battery; wherein the system is configured to apply a charging current from the battery charger by calculating an open cell anode voltage and an anode resistance of the battery, and determining the charging current. In additional arrangements, lithium ion plating is prevented by the charging current. Additional methods and arrangements are disclosed.

Abstract: Disclosed examples include systems and methods for determining an internal short condition in a battery. The method includes computing an estimated current value based on a measured battery voltage, a measured battery current, a measured battery temperature, and a model of the battery that includes steady state characteristics of the battery and transient characteristics of the battery. The method further includes computing an internal short current value according to the measured battery current and the estimated current value, and determining if a battery short condition exists according to the internal short current value.
