A charging station includes a main body, a central emission module, a supersonic receiver, a controller, and a lateral emission module having a left infrared emitter and a right infrared emitter. The controller drives the left infrared emitter and the right infrared emitter to emit alternatively infrared signals to a first signal area and a second signal area, respectively. When the supersonic receiver receives a supersonic signal from the self-propelled apparatus, the controller drives the central emission module to emit another infrared signal to a third signal area so as to guide the self-propelled apparatus to enter the third signal area. When a distance between the self-propelled apparatus and the charging port is smaller than a predetermined distance, the self-propelled apparatus turns to have a charging-input unit thereof to face the charging port. In addition, a charging system including the charging station and the self-propelled apparatus is also provided.
