Techniques for charging and/or discharging a battery using frequency modulation
Abstract
Described herein are techniques that increase the charging and/or discharging rate of a rechargeable battery, at least in part, by using frequency modulated (FM) signals having a frequency in the megahertz (MHz) frequency range. In some embodiments, the MHz frequency range may include any frequency between 0.1 MHz and 1 gigahertz (GHz). In some embodiments, a battery charger described herein may be configured to generate and transmit, to a battery, an FM signal modulated over a frequency range during a period of time, the FM signal having a frequency of at least 0.5 MHz during at least a first portion of the period of time. In some embodiments, a method described herein includes transmitting an FM signal modulated over a frequency range during a period of time and having a frequency of at least 0.5 MHz during at least a first portion of the period of time to a battery.
