In an in-vehicle charging system, a charging display function is improved while versatility of the system is ensured, and usability is improved by enhancing charging display content. An EV controller (4) calculates a charge amount and outputs the calculated charge amount and a state of charge of a battery (2) to a communication line (9). A meter device (6) calculates a time required for completing charging of a battery based on the charge amount and the state of charge of the battery received via the communication line (9), and then calculates an end time based on the required time to display the end time on a display (5) while controlling colored lighting that indicates a remaining required time in accordance with the set time determined in advance.
