Abstract: Methods, systems, and computer-readable media may charge a battery. A value of at least one battery parameter is determined, and a range of values to which the value of the at least one battery parameter corresponds to is identified. Based on the identified range of values, a set of values for at least one charging parameter is determined, and a battery is charged while a value of the at least one charging parameter is swept among the set of values.

Abstract: Various systems and methods for enhancing the performance and utilization of a battery system are described. In one method, a configuration schedule for a battery system is determined based on communications received from an external unit and the cells of the battery system are reconfigured according to the determined configuration schedule. In another method, a sequence of one or more pulses is used for energy transfer from or to at least one cell of the battery system, wherein at least one parameter of one of the sequence and the one or more pulses, is varied in a random manner. The above-noted pulse sequence may be utilized while the battery system is not supplying power to an external load.

Abstract: A method for charging a battery cell includes first transferring of energy from a power source to a plurality of capacitive regions in the battery cell followed by transferring of charge stored in the plurality of capacitive regions of the battery cell into at least an electrolytic mixture that comprises the battery cell and electrodes immersed in the electrolyte mixture. The capacitive regions in the battery cell comprise capacitive double layers between the electrolyte mixture and particles of active material that comprise the battery cell. The transferring of energy from the power source to the capacitive regions occurs for a first duration of time sufficient to substantially fully charge the capacitive regions.

Abstract: Disclosed is pulse charging of a battery that uses frequency modulation to vary the pulse periods of the charging pulses. Battery measurements can be made to determine the duty cycles of the charging pulses.

Abstract: Methods and apparatuses are described for use in preserving and/or recovering the lifetime and charge storage capacity of batteries. The methods include pulse charging, energy juggling, energy leveling, all resulting in extended battery life. Methods of storing batteries for maintaining their capacity at their nominal level for extended periods of time are also presented.

Abstract: A battery charging circuit can produce a pulsed charging current to charge a battery. During charging, without disconnecting the pulsed charging current from the battery, EIS measurements can be made. In other words, the pulsed charging current can serve double-duty, for battery charging and as a drive signal for the EIS measurements. The EIS measurements can be used to alter parameters of the pulsed charging current to improve battery life. In some instances, the parameters of the pulsed charging current can be momentarily changed for the purpose of making the EIS measurements, and then restored subsequent to making the measurements to parameters suitable for battery charging.
