Automatic dual mode battery charger

Patent ·
OSTI ID:6424583
This invention relates to an automatic dual mode battery charging circuit which includes rectifying means and an adjustable voltage rectifier energized by the rectifying means and providing an output to a battery to be charged. The circuit includes a voltage controller connected to the voltage regulator means to set the level of voltage output from the voltage regulator and hence the charging current to the battery. The voltage regulating means provides two modes of operation, namely, a fast charge and a float mode of operation. A current detector connecting in series circuit with the voltage regulator and the battery provides a means for detecting current flow through the battery and controls the operation of the voltage controller, to change the output of the voltage regulating means between the two modes of operation.
