A wireless communication unit wirelessly communicates with a terminal device. An infrared light receiving diode receives infrared light having a digital pattern representing an attachment check response signal from the cable installment type charging control device, and receives infrared light having a digital pattern representing electric vehicle charging related information from the cable installment type charging control device. An attachment check unit checks whether the add-on communication apparatus is attached to the cable installment type charging control device or not on the basis of the attachment check response signal. The attachment check unit changes a state of the add-on communication apparatus on the basis of whether the add-on communication apparatus is attached to the cable installment type charging control device. |
