Abstract: A method and system for charging a rechargeable battery, such as a Lithium based battery, by applying a voltage charge signal, and monitoring a battery charging current and a varying internal resistance of the rechargeable battery and changes in open circuit voltage of the rechargeable battery. The voltage charge signal is dynamically established as a function of the varying internal resistance of the rechargeable battery during charging and the changes in open circuit voltage of the rechargeable battery. The voltage charge signal is a function of a state of charge (SOC) of the rechargeable battery.

Abstract: The object of the invention is a method for charging a rechargeable battery having non-liquid electrolyte, which battery has an internal resonance frequency. The charging process contains at least one charging interval performed with current pulses, the frequency of said current pulses is essentially identical with the internal resonance frequency of the battery to be charged. Following the charging interval consists of periodic current pulses optionally a second relaxation interval is inserted, in which no charging current is applied to the rechargeable battery, within which optionally a second discharging interval is applied. After the second relaxation interval the charging is performed in an interval consists of a continuous charging current, whereafter an optional first relaxation interval is inserted, within which optionally a second discharging interval is applied. This sequence of the above steps can be varied and applied repeatedly until the full charge of the battery is attained.
