SYSTEMS AND METHODS FOR HARMONIC-BASED BATTERY CHARGING

Aspects of the present disclosure involve charging or discharging an electrochemical device such as a battery. The system generates a waveform, such as a charge signal, to tune harmonic attributes of the waveform based on the impedance of the battery to a harmonic or harmonics of the waveform. The system may enhance (e.g., add or increase magnitude) or suppress (e.g., delete or reduce magnitude) harmonics of the waveform. Such a harmonically tuned waveform may optimize energy transfer to or from the battery to achieve various possible goals including charging speed, enhancing battery charge capacity and/or enhancing battery cycle life.
