Zusammenfassung:	The present invention provides a power controller (13), a power supply system (1, 1', 100, 100') and control method thereof. The power command value (Pref) is adjusted according to the state of the power supply system (1, 1', 100, 100') and the characteristic of the secondary battery (12). When the converting power (Pc) of the power converter (11) is larger than or equal to the power command value (Pref), or when the charging current (13) is smaller than the minimum charging current, the power controller (13) performs the power adjusting mode for providing the first preset output current value (Irefl). The power converter (11) adjusts the converting power (Pc) according to the first preset output current value (Irefl). When the charging current (13) is larger than or equal to the maximum charging current, the power controller (13) performs the charging control mode for providing the second preset output current value (Iref2). The power converter (11) adjusts the output current according to the second preset output current value (Iref2).
