Abstract: An evaluation jig comprises a pair of female terminals connectable to a pair of male terminals of a charging connector, and an adjustment member that can adjust contact resistance of the female terminal and the male terminal. The female terminal is reducible in diameter. The adjustment member can apply an external force to the female terminal to reduce the female terminal in diameter.

Abstract: A charging apparatus includes a plurality of batteries, a changeover relay that can be changed over between a first state where the plurality of the batteries are connected in series to one another and a second state where the plurality of the batteries are connected in parallel to one another, an electric storage device, a main relay that is provided between the electric storage device and an electric load of a vehicle, and a control device that controls the opening/closing of the changeover relay. The control device renders the changeover relay in the first state when the main relay is in an open state.

Abstract: 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.

Abstract: An electric power control device for a vehicle which is configured to receive direct current which is supplied from a charging device outside the vehicle and includes an electric storage device configured to be charged by the direct current includes an electronic control unit configured to: acquire maximum output information of the charging device; while the electric storage device is charged by the direct current supplied from the charging device, execute a current limiting process in which the direct current becomes lower than a predetermined value when a parameter relevant to a temperature of a current-carrying component and a threshold of the parameter satisfy a predetermined condition, the current-carrying component being a component in which the direct current flows through; and set the threshold based on the maximum output information of the charging device.

Abstract: An electrically-driven vehicle includes a high-capacity battery unit and a high-output battery unit, both of which supply electric power to rotating electric machines, and a charging inlet serving as a charging port of an external power supply. The high-capacity battery unit receives more charge power from the charging inlet than the high-output battery unit and is positioned nearer to the charging inlet than the high-output battery unit is to the charging inlet. In this way, an electric power loss increase caused by a wiring resistance during an external charge can be suppressed in a plug-in type electrically-driven vehicle, which is chargeable by an external power supply.

Abstract: A power feed system includes a power feed controller that controls a plurality of vehicles including a first vehicle and a second vehicle to successively carry out external power feed in a relayed manner. In passing on external power feed in the relayed manner from the first vehicle to the second vehicle, the power feed controller controls the first vehicle and the second vehicle to make transition from external power feed by the first vehicle to external power feed by the second vehicle with an overlapping period being interposed. During the overlapping period, both of the first vehicle and the second vehicle simultaneously carry out external power feed. The power feed controller controls at least one of the first vehicle and the second vehicle to set total electric power to target electric power during the overlapping period.
