Abstract
(EN)
In order to suppress suction of dew condensation water caused by a capillary phenomenon while realizing miniaturization of a power supply device, a power supply device according to an aspect of the present invention is provided with: a plurality of battery cells (1) that each have a flat rectangular-parallelepiped shape; and a plurality of separators that insulate the adjacent battery cells (1). Each of the separators includes a heat-insulating sheet (24) that is disposed between the adjacent battery cells (1), and an insulative molding member (22) that holds the heat-insulating sheet (24). The molding member (22) has a lower wall (26) that covers the lower surfaces of the adjacent battery cells, and a holding part (23) that holds the heat-insulating sheet (24) in a state of having a gap from the lower wall (26).

Afin de supprimer l'aspiration de l'eau de condensation de rosée provoquée par un phénomène capillaire tout en réalisant la miniaturisation d'un dispositif d'alimentation électrique, un dispositif d'alimentation électrique selon un aspect de la présente invention comprend : une pluralité d'éléments de batterie (1) qui ont chacun une forme de parallélépipède rectangle plat ; et une pluralité de séparateurs qui isolent les éléments de batterie adjacents (1). Chacun des séparateurs comprend une feuille d'isolation thermique (24) qui est disposée entre les éléments de batterie adjacents (1), et un élément de moulage isolant (22) qui maintient la feuille d'isolation thermique (24). L'élément de moulage (22) a une paroi inférieure (26) qui recouvre les surfaces inférieures des éléments de batterie adjacents, et une partie de maintien (23) qui maintient la feuille d'isolation thermique (24) dans un état ayant un espace à partir de la paroi inférieure (26).
