Title (EN) LITHIUM ION BATTERY PACK HAVING PASSIVE COOLING
(FR) BLOC DE BATTERIES AU LITHIUM-ION À REFROIDISSEMENT PASSIF
Abstract:
(EN) A lithium ion battery pack battery pack is disclosed. The battery pack comprises a housing, the housing having a sidewall and a sidewall opening extending there through, a plurality of lithium ion battery cells disposed within the housing, the battery cells having an anode terminal and a cathode terminal, first and second current collectors disposed in the housing, the first and second current collectors electrically engaging respective ones of the anode and the cathode terminals, a metal plate disposed in the sidewall opening adjacent one of the current collectors, and an electrically non-conductive barrier disposed between the adjacent one of the current collectors and the metal plate, wherein the metal plate draws heat from the adjacent one of the current collectors outwardly into the ambient environment.
(FR) La présente invention concerne un bloc de batteries au lithium-ion. Le bloc de batteries comprend un logement, le logement comportant une paroi latérale et une ouverture de paroi latérale s'étendant à travers, une pluralité d'éléments de batterie au lithium-ion disposés dans le logement, les éléments de batterie comportant une borne anode et une borne cathode, un premier et un second collecteur de courant disposés dans le logement, les premier et second collecteurs de courant se raccordant électriquement aux bornes anode et cathode respectives, une plaque de métal disposée dans l'ouverture de paroi latérale à proximité de l'un des collecteurs de courant, et une cloison électriquement non conductrice disposée entre le collecteur de courant à proximité et la plaque de métal. La plaque de métal capte la chaleur provenant du collecteur de courant à proximité et l'évacue dans l'environnement ambiant.
