Abstract[English]
The present invention is related to a battery pack (101). The battery pack (101) comprising a plurality of battery modules (201), one or more of said battery modules (201) includes one or more electrochemical cells (202). A plurality said baffle structure (403) being attached to said battery module (201). A casing assembly (102) being configured to accommodate the plurality of battery modules (201). The casing assembly (102) includes a bottom casing (102C) being configured to have a plurality of fins (103). According to the above architecture, the improved thermal management system provides a controlled recirculation of air through the baffle structure (403) which provides a serpentine path of a recirculated air between the battery modules (201) to provide uniform cooling throughout the battery pack (101). Further, recirculated air exchanges heat with outside air due to heat convection when passes through the bottom casing (102C).[French]
La présente invention concerne un bloc-batterie (101). Le bloc-batterie (101) comprenant une pluralité de modules de batterie (201), un ou plusieurs desdits modules de batterie (201) comprenant une ou plusieurs cellules électrochimiques (202). Une pluralité de ladite structure de déflecteur (403) étant fixée audit module de batterie (201). Un ensemble boîtier (102) étant configuré pour recevoir la pluralité de modules de batterie (201). L'ensemble boîtier (102) comprend un boîtier inférieur (102C) configuré pour avoir une pluralité d'ailettes (103). Selon l'architecture ci-dessus, le système de gestion thermique amélioré fournit une recirculation contrôlée d'air à travers la structure de déflecteur (403) qui fournit un trajet en serpentin d'un air recyclé entre les modules de batterie (201) pour fournir un refroidissement uniforme à travers le bloc-batterie (101). En outre, de l'air recyclé échange de la chaleur avec l'air extérieur en raison de la convection de chaleur lorsqu'il passe à travers le boîtier inférieur (102C).
