Abstract: A CEMS server creates a first plan and a second plan such that a timing of a first change process of a first vehicle and a timing of a second change process of a second vehicle are staggered.

Abstract: When the battery is charged and discharged based on DR request, the first mode display is displayed on the display unit of the mobile terminal. The first mode display includes an end button, and when the end button is operated, the communication unit notifies the server that charging and discharging of the battery is stopped. When the user operates the end button, the mobile terminal notifies the server, so that the server can detect that the user intentionally leaves DR request.

Abstract: A mobile terminal functioning as a display device includes a first acquisition unit that acquires a first schedule indicating a time period in which charging or discharging of the power storage device is scheduled, a second acquisition unit that acquires a second schedule indicating a time period in which a demand response requesting charging or discharging of the power storage device is scheduled, and a display unit that displays a schedule window. The display unit simultaneously displays the first schedule and the second schedule on the schedule screen in an identifiable manner.

Abstract: A management system includes: a management device that manages incentives given to an administrator who manages an electric power device that is electrically connectable to an external power supply; and a display device that displays the incentives received from the management device. The management device includes a storage unit that stores data on the incentives of the administrator, and an update unit that updates the data stored in the storage unit in such a manner that, when the electric power device meets a predetermined requirement, an incentive corresponding to the requirement met is given to the administrator. The display device includes a classification unit that classifies the incentives earned by the administrator according to situations, and a first display unit that displays the incentives classified according to each of the situations by the classification unit in such a manner that the incentives for each situation are respectively identifiable.

Abstract: A hybrid vehicle is equipped with an engine that is connected to a power split mechanism, a generator, an electric motor, and also a stepped transmission that is arranged between the electric motor and a drive shaft. An electronic control unit (an ECU) with which this hybrid vehicle is equipped revises a down line downward to make a downshift likely to occur when at least one of a prescribed generator condition and a prescribed electric motor condition is fulfilled. The generator condition includes that the temperature of the generator is equal to or higher than a first reference temperature and that an absolute value of a rotational speed of the generator decreases due to the making of the downshift. The electric motor condition includes that the temperature of the electric motor is equal to or higher than a third reference temperature.
