Abstract
(EN)
The present application provides a thermal management device, a battery pack, and a new energy vehicle. The thermal management device comprises a thermal management loop, the thermal management loop being attached to each battery cell and at least partially covering an explosion-proof valve of each battery cell; a heat exchange member, communicated with the thermal management loop; and a power member, connected between the thermal management loop and the heat exchange member, wherein the thermal management loop is provided with a heat exchange medium having a fire extinguishing function which can damage the thermal management loop during the thermal runaway of any battery core, so that the heat exchange medium flows into the thermal management loop along an explosion-proof opening of the battery core.
(FR)
La présente invention concerne un dispositif de gestion thermique, un bloc-batterie, et un véhicule à énergies nouvelles. Le dispositif de gestion thermique comprend une boucle de gestion thermique, la boucle de gestion thermique étant fixée à chaque élément de batterie et recouvrant au moins partiellement une vanne antidéflagrante de chaque élément de batterie ; un élément d'échange de chaleur, en communication avec la boucle de gestion thermique ; et un élément d'alimentation, connecté entre la boucle de gestion thermique et l'élément d'échange de chaleur, la boucle de gestion thermique étant pourvue d'un milieu d'échange de chaleur ayant une fonction d'extinction d'incendie qui peut endommager la boucle de gestion thermique pendant l'emballement thermique de n'importe quel noyau de batterie, de telle sorte que le milieu d'échange de chaleur s'écoule dans la boucle de gestion thermique le long d'une ouverture antidéflagrante du noyau de batterie.
