Title
(EN) METHOD AND APPARATUS FOR MANAGING THERMAL RUNAWAY GASES IN A BATTERY SYSTEM
(FR) PROCÉDÉ ET APPAREIL DE GESTION DE GAZ D'EMBALLEMENT THERMIQUE DANS UN SYSTÈME DE BATTERIE
Abstract
(EN)
A system comprising one or more battery modules mounted in a rack assembly has a structure which defines a cooling air pathway for flowing cooling air across the side and/or bottom of each battery module thereby cooling the battery module, or alternatively, across the energy calls in the battery module. Further, the system has a structure which defines a thermal runaway gas pathway for flowing thermal runaway gases from a battery module out of the system. The system structure is configured to ensure that the cooling air pathway and thermal runaway gas pathway are physically separated, thereby minimizing the risk of the thermal runaway gas substantially mixing with cooling air thereby potentially resulting in a spontaneous ignition and an explosion.

La présente invention concerne un système comprenant un ou plusieurs modules de batterie montés dans un ensemble de bâti qui a une structure qui définit un trajet d'air de refroidissement pour faire circuler de l'air de refroidissement de part et d’autre du côté et/ou du fond de chaque module de batterie de façon à refroidir le module de batterie, ou en variante, à travers les appels d'énergie dans le module de batterie. En outre, le système a une structure qui définit un trajet de gaz d'emballement thermique pour faire circuler des gaz d'emballement thermique depuis un module de batterie hors du système. La structure de système est configurée pour s'assurer que le trajet d'air de refroidissement et le trajet de gaz d'emballement thermique sont physiquement séparés, de façon à réduire au minimum le risque que le gaz d'emballement thermique se mélange sensiblement à l'air de refroidissement de façon à conduire potentiellement à un allumage spontané et une explosion.
