  • Patent number: 11958409
    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.

  • Publication number: 20230302944
    Abstract: An evaluation jig comprises a female terminal connectable to a male terminal of a charging connector. The female terminal includes a plurality of contact pieces and a support portion. Each contact piece has a flexible piece, and a contact portion protruding toward the center axis from an inner surface of the flexible piece. The flexible piece forms a portion of a cylinder having the center axis. The flexible piece has a length equal to or larger than twice an outer diameter of the cylinder in a direction parallel to the center axis. The flexible piece is elastically deformable so that the flexible piece has a distal end portion to be displaceable in a radial direction of the cylinder relative to a proximal end portion of the flexible piece. The contact portion has a shape curved so as to protrude inward in the radial direction.

  • Publication number: 20220334143
    Abstract: An evaluation method is a method for evaluating a charging connector in coolability by connecting an evaluation jig to the charging connector, the charging connector including a pair of male terminals coolable with a coolant, the evaluation jig including a pair of female terminals, the pair of female terminals being connected to the pair of male terminals in evaluating the charging connector in coolability. The method comprises: connecting the pair of female terminals to the pair of male terminals; adjusting a connection state between the male terminal and the female terminal such that contact resistance between the terminals is 0.06 m? or more and 0.15 m? or less; and after the adjusting, evaluating the coolability depending on whether the male and female terminals have a temperature of 90° C. or lower when a charging current of 400 A is supplied to the terminals for 30 minutes.

  • Patent number: 11460424
    Abstract: An evaluation method is for evaluating a charging connector in coolability by connecting an evaluation jig to the charging connector, the charging connector including a pair of male terminals and a bottom wall, the evaluation jig including a pair of female terminals, the pair of female terminals being connected to the pair of male terminals in evaluating the charging connector in coolability. The method comprises: connecting the pair of female terminals to the pair of male terminals; and adjusting a connection state of the terminals so that contact resistance between the terminals falls within a prescribed range. In the step of adjusting, a resistance between a point of 4.5 mm of the male terminal from a surface of the bottom wall and a point of 43 mm of the female terminal from the surface of the bottom wall is measured as the contact resistance.

  • Patent number: 11358490
    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.
