Abstract: An immersion-cooled battery module according to the present disclosure can includes a battery assembly with a plurality of battery units. A module case of the battery module can extend in a first direction and have an opening at least at one end in a first direction. The module case can accommodate the battery assembly and a cooling liquid in an internal space of the module case connected to the opening. A sealing cover is configured to airtightly seal the opening.

Abstract: A gas venting device, and a battery module and a battery pack including same has a gradually reducing cross-sectional area of a flow path in a gas discharge direction so that a greater flow rate of gas can be discharged even when a venting disc having the same area is used.

Abstract: An immersion cooled battery module includes a plurality of sub battery modules; a module case having an opening in at least one end, and accommodating the plurality of sub battery modules and a cooling liquid in an internal space connected to the opening; a sealing cover air-tightly covering the opening; a plurality of circuit boards corresponding to the plurality of sub battery modules, received in the internal space and configured to sense electrical signals related to the plurality of sub battery modules; and a waterproof connector coupled to the sealing cover, and configured to transmit the electrical signals respectively sensed by the plurality of circuit boards to an external device outside of the module case.

Abstract: Disclosed herein is a gas venting device, a battery module and a battery pack including the same. A cross-sectional area of a flow path according to a gas discharge direction of the gas venting device is increased or decreased to allow a larger flow amount of gas to be discharged using a venting disk of the same area.

Abstract: Disclosed herein is a gas venting device, and a battery module and a battery pack including the same. A cross-sectional area of a flow path according to the gas discharge direction of the gas venting device can be increased or decreased to allow a larger flow rate of gas to be discharged with a venting disk of the same area. The venting disk can be installed on an outlet side of the gas discharge flow path to protect internal components, and the like.

Abstract: Disclosed herein is gas venting device, and a battery module and a battery pack including the same. A cross-sectional area of a flow path according to the gas discharge direction of the gas venting device is increased or reduced to allow; a larger flow rate of gas to be discharged even when using a venting disk of the same area. A venting disk can be installed on the inlet side of the gas discharge flow path to protect internal components, and the like.

Abstract: A battery pack includes a battery pack; a charging housing having an inlet, an outlet, and a pack insertion space into which the battery pack is insertable; a charging part electrically connected to the battery pack inserted into the pack insertion space, for charging the battery pack; a circulation part configured to supply cooling water supplied to the pack insertion space through the inlet and recover cooling water from the pack insertion space through the outlet; a heating part configured to heat to the pack insertion space; and a control part for controlling the charging part, the heating part, and the circulation part.

Abstract: A gas venting device, has a flow path with a cross sectional area that is continuously reduced in a gas discharge direction. This allows a larger amount of gas to be discharged compared to a venting disk having the same area . The gas venting device can be used with a battery module and a battery pack.
