There is provided a method for manufacturing an electric junction box that includes: a first bus bar and a second bus bar having one shape selected from a plurality of types of shapes; a housing that accommodates the first bus bar and the second bus bar; and a plurality of input and output portions to which a terminal connected to an external power supply is connectable. The manufacturing method includes: a first operation of providing the first bus bar and the second bus bar that have one of predetermined shapes selected based on a specification of the electric junction box; and a second operation of accommodating the first bus bar and the second bus bar provided by the first operation in the housing.

Method for manufacturing electric junction box

An electric connection box includes a housing configured to accommodate at least one electronic component and an attachment portion provided on the housing, the attachment portion including a through hole through which a fastening member is to be inserted and an attachment surface configured, when the housing is attached to an object, to face the object, the housing being to be attached to the object at the attachment portion by the fastening member. A plurality of recessed portions are provided around an edge portion defining the through hole, the plurality of recessed portions being provided on the attachment surface. At least one of the plurality of recessed portions is provided with an entry prevention portion configured to prevent the fastening member from entering the recessed portion.

Electric connection box

A wire harness includes an electrical connection box. The electrical connection box includes a body in which an electronic component is mounted and a lower cover. The lower cover covers a rectangular frame and a vertically lower end portion of the rectangular frame, and includes: a bottom disposed parallel to a panel of a vehicle body, the panel facing the lower cover; an inlet having the smallest distance from the panel; and a channel-forming depression. The channel-forming depression is provided on the vertically lower side than the inlet, formed by bending at least a part of the bottom toward the inside of the lower cover, and formed along a surface of the panel, so as to allow liquid that has entered between the bottom and the panel to flow to the outside.

Electrical connection box and wire harness

An electrical connection box applied to a wire harness includes a casing and a cover member. The casing is provided with a first member that houses an electronic component and a second member and an insertion port formed on the first member, and an exterior installation unit formed outside the insertion port of the first member with an end of an exterior member of which being arranged in a stacking direction. The cover member has a pair of locking units, and is locked to the exterior installation unit via the pair of locking units and holds an end of the exterior member between the cover member and the first member. The second member includes a pressing wall that interposes an end to be pressed of the cover member between the pressing wall and the first member and that presses the end to be pressed toward the first member side.

An electronic component unit includes a housing which accommodates an electronic component therein, which includes a bottom surface in a vertical direction and a side wall surface, and to which a connection portion with electric wire is provided on the bottom surface. The bottom surface of the housing includes an inclined surface. One side of the inclined surface disposed on a side of the side wall surface is positioned at a lower position in the vertical direction than the other side of the inclined surface disposed on a side of the connection portion.

Electronic component unit

A method of estimating a state of charge of a battery, a method of estimating an open circuit voltage of a battery, and a method and device for computing a degradation degree of a battery are provided. As a degradation degree, a ratio of a total electrical quantity chargeable or dischargeable of a battery at any time point to an initial electrical quantity that is a total electrical quantity chargeable or dischargeable of the battery upon non-degradation is computed, and by using the degradation degree, a state of charge or an open circuit voltage of the battery is accurately estimated.
