Publication number: 20240075840Abstract: A VGI system includes a plurality of BEVs, a plurality of pieces of EVSE, and a server. The server determines whether the BEV exchanges electric power with a power grid with the use of second EVSE provided in a second area, the second area being different in manner of management of power supply by the power grid from a first area where predetermined first EVSE is provided, the first EVSE being normally used by the BEV. When the server determines that the BEV exchanges electric power with the use of the second EVSE and when the second area is higher than the first area in contribution to DR in exchange of electric power by the BEV, the server grants an incentive higher than in exchange of electric power with the power grid with the use of the first EVSE.Type: ApplicationFiled: August 29, 2023Publication date: March 7, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Publication number: 20240067039Abstract: An operation management server manages a vehicle equipped with a battery able to store regenerated electric power. The operation management server includes: a processor that generates a message to be transmitted to the vehicle; and a storage that stores traveling histories of a plurality of vehicles. The processor estimates a transition in a power storage amount of the battery on a planned travel route of the vehicle based on a travel plan of the vehicle and the travel histories of the vehicles. The processor generates the message for proposing execution of external power supply from the battery to an outside of the vehicle before the power storage amount reaches a predetermined amount, when an estimation is made that the power storage amount will exceed the predetermined amount on the planned travel route.Type: ApplicationFiled: June 9, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Publication number: 20240037597Abstract: A server manages power adjustment resources electrically connected to a power network. The power adjustment resources include power equipment installed in a facility and configured to supply power from a vehicle to the power network and charge power from the power network to the vehicle. When reservation information for using the facility is received from a user, the server predicts a power supply-demand balance in the power network on a reserved date and time of use of the facility. When a DR for adjusting the power supply-demand balance is predicted to be performed on the reserved date and time of use, the server prepares a use plan for the facility so as to include the vehicle participating in the DR using the power equipment. The server gives an incentive to the user when the user accepts the use plan.Type: ApplicationFiled: June 1, 2023Publication date: February 1, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Publication number: 20240025288Abstract: A server manages power balancing resources electrically connected to a power network. The server includes a processor. In response to receipt of input of a travel schedule including a date and time of travel, a departure point, and a destination point from a user of the vehicle, the processor predicts a power supply and demand balance on the power network for the date and time of travel, based on power supply and demand performance information of the power network. In response to prediction that the power supply and demand balance is going to be adjusted on the date and time of travel, the processor provides the user suggestion to keep the vehicle connected to the power equipment on the date and time of travel and a reward for the vehicle responding to a request to adjust the power supply and demand balance.Type: ApplicationFiled: May 18, 2023Publication date: January 25, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA
