Abstract (en)
[origin: WO2022026934A1] Systems and methods that charge a battery using a signal with at least one harmonically tuned aspect based on impedance of the battery with a frequency or harmonic component. The system may further involve a power converter that may act in concert with charging to power a load. In some instances, an output signal is generated that is interleaved with the charge signal. Further, the output signal may be tuned based on output impedance to the discharge signal.
