Abstract: front page image
(EN)A battery pack (1) comprising a secondary battery (2), a molded body (11) which houses the secondary battery inside, and a foamable layer (12) which is arranged between the secondary battery and the inner surface of the molded body and foamed at a predetermined temperature or higher, thereby forming a foamed heat insulation layer.  Consequently, even though the heat insulation layer contained in the battery pack is thin during the normal state in which the battery contained in the pack does not generate heat, the insulation layer exhibits a high heat insulation effect once an abnormal state occurs, thereby suppressing a temperature increase in the surface of the battery pack.
(FR)L’invention concerne un bloc-batterie (1) se composant d’un système de batterie secondaire (2), d’un corps moulé (11) contenant le système de batterie secondaire, d’une couche aux propriétés expansibles (12) disposée entre la surface intérieure du corps moulé et le système de batterie secondaire, et qui, en cas de température supérieure à la température déterminée, connaît une expansion de sorte à former une couche d’isolation expansée. Ainsi, la couche d’isolation entourant le bloc-batterie est de faible épaisseur en cas de conditions normales, lorsque les batteries insérées ne génèrent aucune chaleur; mais en cas d’anomalie, ses propriétés isolantes sont élevées et elle permet de supprimer l’augmentation de température à la surface du bloc-batterie.
(JA) 本発明の電池パック1は、二次電池2と、二次電池を内部に収容する成形体11と、二次電池と成形体の内表面との間に設けられ、所定の温度以上で発泡して発泡断熱層を形成する発泡可能層12と、を有する。これにより、収納された電池が発熱していない正常時には電池パックに含まれる断熱層が薄いものでありながら、異常発生時には高い断熱効果を発揮して電池パック表面の温度上昇が抑制される。
