Abstract: This battery unit is a battery unit including a battery pack that houses a battery cell, and a water-cooling medium flow path formed outside a bottom surface of the battery pack, in which the water-cooling medium flow path of the battery pack is made of an Al-based plated steel sheet.

Abstract: This battery unit is a battery unit including a battery pack that houses a battery cell, and a water-cooling medium flow path formed outside a bottom surface of the battery pack, in which the water-cooling medium flow path is made of a Zn-based plated steel sheet, an inorganic film or a resin film is formed as a chemical conversion coating film on a surface of the Zn-based plated steel sheet, and the inorganic film contains a Si-based component or a Zr-based component as a main component.

Abstract: A transporting apparatus has two storage means with plate form body supporting members in a plurality of stages in vertical direction. Each plate form body supporting member is constructed with a plurality of string like members having widths to pass through clearance between adjacent transporting rotary bodies for vertical movement therethrough and arranged on the same plane for simply being lifted up and down for loading and unloading the plate form body. The storage mean scan be arranged within an installation region of the transporting passage portion. Also, necessary length of the transporting passage portion is merely two or three times of the plate form body. The storage means can be installed in a relay transporting passage portion arranged between two transporting lines arranged in parallel relationship to facilitate installation with simple and compact construction.
