The invention relates to a battery pack with exhaust conduits and airflow channels for thermal runaway protection. The battery pack includes an elongate exhaust conduit defining an airflow channel. The discharge conduit includes a longitudinal central axis and a tip having a battery pack vent. The battery pack also includes a sheet disposed within the airflow channel, and a plurality of battery cells disposed adjacent to the discharge conduit. Each respective battery cell includes a housing defining a battery cell cavity. The housing defines a cell ventilation opening. An anode and a cathode are disposed within the cell cavity, and a vent cover covers the cell vent opening. The vent cover opens at a predetermined pressure to release hot gas from the battery cell cavity into the gas flow channel. The sheet directs the hot gas along the longitudinal central axis and towards the end of the exhaust conduit, and thus to the battery pack vent for exhaust into the surrounding environment. 本发明涉及具有用于热失控保护的排出导管和气流通道的电池
