摘要： A battery pack includes an elongated exhaust conduit defining a gas flow channel. The exhaust conduit includes a longitudinal center axis and a terminal end having a pack vent. The battery pack also includes fins disposed within the gas flow channel, and a plurality of battery cells arranged adjacent to the exhaust conduit. Each respective battery cell includes an outer casing defining a cell cavity. The casing defines a cell vent opening. An anode and a cathode are disposed within the cell cavity, and a vent cap covers the cell vent opening. The vent cap opens at a predetermined pressure to release hot gasses from the cell cavity into the gas flow channel. The fins direct the hot gasses along the longitudinal center axis and toward the terminal end of the exhaust conduit, and thus to the pack vent for discharge to the surrounding ambient environment.
