Claim Text:
1. An apparatus for simulating battery, comprising: a power supplying unit, coupled to a power terminal of a battery interface, and determining whether to provide an operation voltage to the power terminal according to a device voltage provided by the power terminal; a state regulating unit, coupled to the power terminal, and providing a impedance regulating signal according to the device voltage, wherein the state regulating unit comprises an error control unit for receiving the device voltage and a first reference voltage, and providing the impedance regulating signal according to the device voltage and the first reference voltage, wherein the first reference voltage is greater than a rated voltage of the battery interface; and an impedance unit, coupled between the power terminal and a ground voltage, and coupled to the state regulating unit to receive the impedance regulating signal, wherein the impedance unit regulates an impedance thereof according to the impedance regulating signal.
