Abstract: A water blocking structure of a wire harness and a method for manufacturing the wire harness is provided. The water blocking structure includes a set of wires including a plurality of wires arranged in at least one row and side by side in a direction of a diameter of the wire, and an integrally molded stopper made of a hard resin that is injection-molded at a low-pressure so as to surround a portion of the set of wires in an extending direction of the wires and to have an outer circumferential shape defining portion that conforms to an inner circumferential shape of a wire passage portion into which the set of wires is to be inserted.

Abstract: A waterproof structure of a wire harness includes at least one bundle of an electric wire group in which a plurality of electric wires are linearly arranged, a damming part made of a hard resin material, the damming part which surrounds a part of the electric wire group in an extension direction of the electric wire group and which includes an outer periphery shape part according to a shape of a trapezoidal through hole in an electric wire group insertion part with a divided structure, and a water stop material which prevents water from entering a gap between the electric wire group insertion part and the outer periphery shape part and which is formed on an inner peripheral surface of the through hole.

Abstract: A cooling system for a battery pack which can reduce the number of components, manufacturing cost and an installation space, is provided. The battery pack includes high-voltage electrically conductive paths connected to a positive electrode and a negative electrode thereof, respectively. The high-voltage electrically conductive path connected to the positive electrode serves as a cooling member. The high-voltage electrically conductive path connected to the positive electrode is arranged along the battery pack to absorb heat generated at the battery pack and dissipate the absorbed heat at a location distant from the battery pack. The invention takes an advantage of the superior heat conductivity of the high-voltage electrically conductive path to cool down the battery pack.
