Abstract
Systems and methods for providing a single power source, multi-output battery charger configured to transition individual batteries coupled to its output from the absorption stage to the float stage independent of other batteries also coupled to its output. The power source may be any suitable power source, such as an AC/DC converter, solar panels, wind generators, alternators, etc. A programmable controller with suitable circuitry is utilized to control a voltage drop across a variable voltage drop blocking device coupled between the output of the power source and a terminal of a rechargeable battery to selectively transition individual batteries coupled to the power source output from the absorption stage to the float stage once they have reached full charge. Using the battery chargers disclosed herein, auxiliary batteries are not subjected to the full absorption voltage for an extended duration after they are charged, thereby reducing the likelihood of undesirable overcharging.
