Abstract

Disclosed is a battery ventilation device (10) and, more particularly, a multifunctional breathing and ventilation device applied to a casing of one of a battery sub-module, a battery module, or a battery system, and the ventilation device (10) comprises: a housing (20) attached to a vent opening of a battery casing in a sealing manner and including at least one sidewall (21); an air-permeable filter (30) for separating the interior (91) of the battery casing from a breathing chamber (22) inside the housing (20); a ventilation membrane (40) for separating the breathing chamber (22) from an external environment (92) in an airtight manner; and a breathing part (50) fluidly connecting the breathing chamber (22) to the external environment (92) and bypassing the ventilation membrane (40). Furthermore, disclosed is a battery comprising the ventilation device attached to the battery casing. The ventilation device and the battery comprising the same, according to embodiments of the present disclosure, can be applied to electric vehicles and energy storage system (ESS) battery packs.

Description

technical field [0001] The present disclosure relates to a venting device for a battery, and in particular, to a multifunctional breathing and venting device for a housing of one of a battery sub-module, a battery module or a battery system, a battery sub-module, a battery module or a battery system. The battery system is configured to be integrated in the housing. Background technique [0002] A rechargeable or secondary battery differs from a primary battery in that the rechargeable or secondary battery can be repeatedly charged and discharged, whereas the primary battery provides only the irreversible conversion of chemical energy to electrical energy. Low-capacity rechargeable batteries are used as power sources for small electronic devices such as cellular phones, notebook computers, and camcorders, and high-capacity rechargeable batteries are used as power sources for hybrid vehicles and the like. [0003] Generally, a rechargeable battery includes: an electrode assem...
