Abstract[English]
The present application belongs to the field of batteries, and specifically relates to a venting busbar, a battery module and a battery pack, which solve the problem of existing battery modules having potential safety hazards. The venting busbar is provided with first through holes corresponding to venting portions of battery cells, and is configured to discharge thermal runaway gases in an ordered manner when the battery module undergoes thermal runaway. When thermal runaway occurs in a battery cell, the thermal runaway gases break through the venting portion of the battery cell and are discharged through the venting busbar, preventing the diffusion of the thermal runaway gases from affecting the remaining battery cells, thereby improving the safety performance of the battery module.[French]
La présente demande appartient au domaine des batteries et concerne spécifiquement une barre omnibus de ventilation, un module de batterie et un bloc-batterie, qui résolvent le problème des modules de batterie existants qui présentent des risques potentiels de sécurité. La barre omnibus de ventilation est dotée de premiers trous traversants correspondant à des parties de ventilation de cellules de batterie et est configurée pour évacuer des gaz d'emballement thermique d'une manière ordonnée lorsque le module de batterie subit un emballement thermique. Lorsqu'un emballement thermique se produit dans une cellule de batterie, les gaz d'emballement thermique pénètrent dans la partie de ventilation de la cellule de batterie et sont évacués à travers la barre omnibus de ventilation, empêchant que la diffusion des gaz d'emballement thermique n'affecte les cellules de batterie restantes, ce qui permet d'améliorer les performances de sécurité du module de batterie.[Chinese]
本申请属于电池领域，具体为一种泄爆汇流管、电池模组及电池包，解决现有电池模组存在安全隐患的问题。泄爆汇流管上具有与单体电池泄爆部相对应的第一通孔，用于电池模组热失控时对热失控烟气进行有序排放。当单体电池发生热失控时，热失控烟气冲破单体电池的泄爆部从泄爆汇流管排出，避免热失控烟气弥散对其余单体电池造成影响，提高电池模组的安全性能。
