ABSTRACT:
A battery-charging device, having a maximum power point tracking (MPPT) function, for a stand-alone generator system includes a DC/DC power converter and a control circuit used to control the DC/DC power converter. The method applied in the device includes: performing a MPPT function to supply a continuous current when the electric power generated from the electrical power source of the stand-alone generator system is low; operating a pulse charging function and continuing the MPPT function when the electric power generated from the electrical power source of the stand-alone generator system is high and not greater than the summation of the load power and a maximum charging power of the pulse charging method for the battery; terminating the MPPT function while the electric power is greater than the summation of the load power and the maximum charging power of the pulse charging method for the battery; and operating a constant-voltage charging mode when the battery voltage is greater than a predetermined constant charging voltage.
