    摘要: Disclosed is an exhaust filter system for a battery pack, including an explosion-proof valve and a filter apparatus. One end of the explosion-proof valve is connected to a battery pack- and the other end is connected to the filter apparatus. The filter apparatus includes an introduction port, a discharge port, a housing, and a filter mechanism. The introduction port and the discharge port are separately disposed at two ends of the housing. The filter mechanism is disposed inside the housing and is provided with a plurality of filter holes. The present invention has the following beneficial effects: by optimal design of a novel explosion-proof valve and a novel filter apparatus, expanding the applicability of technical solutions of this application, solving the problem of fire induced by thermal runaway, exhausting combustion gas more smoothly, and achieving better effects of filtering and post handling for thermal runaway in a battery pack.

    摘要: The present disclosure refers to a ventilation device for a battery, particularly to a multifunctional breathing and venting device for a casing of one of a battery submodule, battery module or battery system, such as for an electric vehicle and an energy storage system (ESS). The ventilation device comprising a housing configured for being attached to a vent opening of a battery casing in a sealing manner and comprising at least one lateral wall, a breathable filter separating an interior of the battery casing from a breathing chamber within the housing, a venting membrane separating the breathing chamber from an exterior environment in a gas tight manner, and a breathing sprout fluidly connecting the breathing chamber and the environment and bypassing the venting membrane. The disclosure further relates to a battery comprising such a ventilation device attached to its casing.
