ABSTRACT:
A battery charger system (10) consisting of a power supply unit (20) and a battery charger unit (70). The power supply unit (20) features a current profile generator (26) that defines a current profile of the output current of the power supply unit (20). The battery charger system (10) provides a unique way of communicating charging current demand between the battery charger unit (70) and the power supply unit (20). The power supply unit (20) is capable of determining the charging current demand by detecting specific logical operating states of the battery charger unit (70), and comparing the current to a set threshold. The battery charger unit (70) communicates charging current demand to the power supply unit (20), and the power supply unit (20) responds by adjusting its output current to meet the required demand.
