Abstract: A battery simulator for simulating the status of a battery connected to a load component includes a controllable current source, a voltage detector, and a gain controller. The controllable current source supplies an output current to the load component according to a current control signal. The voltage detector measures a detection voltage that is generated in response to the output current flowing through the load component. The gain controller is electrically connected to the controllable current source and the voltage detector and generates the current control signal according to a voltage control signal, a gain control signal and the detection voltage.
