Abstract
(EN) A thermal runaway detection method and a battery management system, capable of effectively detecting the occurrence of thermal runaway of a battery. The method comprises: obtaining at least one parameter of a cooling medium of a battery (710), the battery comprising a heat-conducting device, and the cooling medium being accommodated in the heat-conducting device; and when the at least one parameter meets a preset condition, determining that thermal runaway has occurred in the battery (720).
(FR) Procédé de détection d'emballement thermique et système de gestion de batterie, pouvant détecter efficacement l'apparition d'un emballement thermique d'une batterie. Le procédé consiste à : obtenir au moins un paramètre d'un milieu de refroidissement d'une batterie (710), la batterie comprenant un dispositif de conduction de chaleur, et le milieu de refroidissement étant logé dans le dispositif de conduction de chaleur; et lorsque le ou les paramètres satisfont à une condition prédéfinie, déterminer qu'un emballement thermique s'est produit dans la batterie (720).
(ZH) 一种热失控检测的方法和电池管理系统，能够有效检测电池的热失控的发生。该方法包括：获取电池的冷却介质的至少一个参数（710），所述电池包括导热装置，所述导热装置中容纳所述有冷却介质；在所述至少一个参数满足预设条件时，确定所述电池发生热失控（720）。
