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.

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.

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.

Abstract: The power conversion system includes an inverter circuit. The inverter circuit performs a grid-connected operation and an independent operation. When performing the independent operation, the inverter circuit may output, via a terminal, AC power converted to a load disconnected from a power grid. When the inverter circuit performs the independent operation, a control unit controls, when operating in a first mode, the power conversion system in a first time range such that an AC voltage is applied to the terminal, and controls, when operating in a second mode, the power conversion system in a second time range different from the first time range. The second mode includes control of stopping an operation of having the AC voltage applied to the terminal.
