Abstract: The insulation resistance testing device of the present disclosure includes a first magnetic current sensor disposed between the control unit and the ground, and a first damping resistor disposed in series with the first magnetic current sensor between the control unit and the ground. The insulation resistance testing device of the present disclosure includes a second magnetic current sensor disposed between the positive terminal and the ground of the battery pack, and a second damping resistor disposed in series with the second magnetic current sensor between the positive terminal and the ground.

Abstract: A manufacturing method of a wire harness which includes at least one bundle of an electric wire group in which a plurality of electric wires are linearly arranged, and a damming part made of a resin material surrounding a part of the electric wire group in an extending direction of the electric wire group and including an outer periphery shape part according to an inner peripheral shape of an electric wire group insertion part, the manufacturing method includes a mold clamping step of disposing a part of the one bundle of the electric wire group and mold clamping an upper mold and a lower mold and an injection step of performing low pressure injection of a larger amount of molten resin than a volume of a cavity into the cavity.

Abstract: A motor cable assembly connecting a motor and an inverter includes a cable main body, which can move flexibly. The cable main body is manufactured and formed into a flat shape by arranging a plurality of cables in parallel in a row, covering an outer surface of the arranged cables with a braid, and covering further an outer surface of the covered cables. The motor cable assembly includes an inverter-side protector having a vibration absorbing portion supporting the cable main body at a position near the inverter-side connecting member so as to absorb the vibrating motion of the cable main body.
