Abstract
In a phase-locked battery charge system, the structure its circuit is similar to a phase-locked loop; by means of its specific auto-tracking and auto-locking capabilities, a complete battery charge process can be accomplished automatically in the order of bulk current charge, variable current charge, and float charge. Therefore, this invention features with its simple circuit structure, good charge current, and assured safe charge effect.
