Abstract:
1. A system for providing battery rejuvenation, comprising: a battery detection system adapted to determine whether a battery is present; a state of charge system adapted to determine a resident charge within the battery; a battery health system adapted to determine a useful capacity of the battery; a modulated current charging signal generation system adapted to generate a modulated first current charging signal at or near a resonant frequency of the battery and provide the modulated current charging signal to the battery; a reduced charging system adapted to generate a modulated second current charging signal at or near the resonant frequency of the battery, if the battery has a charge acceptance capacity lower than the battery's rated capacity, the second current charging signal having a magnitude less than the first current charging signal; and a full charge system adapted to provide the modulated first current charging signal to the battery at full rate.
