Abstract: front page image
(EN)A battery pack (1) comprising a secondary battery (2), a molded body (11) which houses the secondary battery inside, a temperature increase-suppressing layer (13) which is arranged between the secondary battery and the inner surface of the molded body for the purpose of suppressing a temperature increase in the outer surface of the molded body, and a block layer (12) which is arranged between the secondary battery and the temperature increase-suppressing layer for the purpose of blocking a material leaked from the secondary battery when such leakage happens.  Consequently, when an abnormal state where a melted content or the like is leaked from the secondary battery occurs, the content is prevented from leaking outside the battery pack, 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 de suppression de l’augmentation de la température (13), disposée entre la surface intérieure du corps moulé et le système de batterie secondaire, qui supprime l’augmentation de température de la surface extérieure du corps moulé, et d’une couche de blocage (12), disposée entre le système de batterie secondaire et la couche de suppression de l’augmentation de température, qui, en cas de fuites s’écoulant depuis le système de batterie secondaire, bloque les fuites susmentionnées. Ainsi, lorsqu’une anomalie se produit, telle que l’écoulement des substances issues par exemple d’une fusion du système de batterie secondaire, ces substances ne peuvent s’écouler à l’extérieur du bloc-batterie et la température de la surface du bloc-batterie ne peut augmenter.
(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、成形体の外表面での温度上昇を抑制する昇温抑制層13と、二次電池と昇温抑制層との間に設けられ、二次電池からの漏出物が生じた場合に当該漏出物をせき止めるブロック層12と、を有する。これにより、二次電池から熔融物等の内容物が流出するような異常が生じた場合に、電池パック外部に内容物が流出するのを防止し、電池パック表面の温度上昇を抑制する。
