Publication number: 20240208410Abstract: An ECU of a vehicle monitors a charging state when charging is started. When a charging power supplied from a multi-outlet charger has changed without detecting and receiving an abnormality, the ECU causes a notification device to notify the changed charging power and a charging time based on the changed charging power. The ECU notifies a communication terminal which is owned by a user of the changed charging power and the charging time based on the changed charging power.Type: ApplicationFiled: March 13, 2024Publication date: June 27, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hidetoshi Kusumi
