Abstract
A battery module includes a cell assembly including a plurality of battery cells, and a module housing having an arrangement space for accommodating the cell assembly and a cover plate covering a top surface of the cell assembly. The cover plate has at least one discharge hole for discharging gas generated in the cell assembly. A blocking member is disposed between the top surface of the cell assembly and the cover plate to block flame or a combustion material from being discharged externally of the module housing through the discharge hole.
Claims16
A battery pack comprising:
- a pack case including a bottom case and a cover case coupled to each other to form an accommodation space;
- and
- a plurality of battery modules accommodated in the pack case,
- wherein each of the plurality of battery modules includes:
- a cell assembly including a plurality of battery cells;
- a module housing having an arrangement space for accommodating the cell assembly and a cover plate covering a top surface of the cell assembly and
- including a plurality of discharge holes for discharging gas generated in the cell assembly;
- and
- a blocking member disposed between the top surface of the cell assembly and the cover plate to block flame or a combustion material from being discharged externally of the module housing through the plurality of discharge holes,
- wherein, in each of the plurality of the battery modules, the plurality of discharge holes are disposed in at least one row,
- wherein the cover case is structured to cover a plurality of cover plates provided in a plurality of module housings,
- wherein the cover case includes a plurality of guide grooves to form a flow space in which the gas discharged through the plurality of discharge holes flows, and
- wherein each of the plurality of guide grooves is structured to cover a plurality of discharge holes arranged in a row on any one of the plurality of cover plates and not to cover other discharge holes disposed on other cover plates to prevent a gas discharged from an inside of one battery module from affecting other battery modules.

A battery pack comprising:
- a pack case including a bottom case and a cover case coupled to each other to form an accommodation space;
- and
- at least one battery module accommodated in the pack case,
- wherein the at least one battery module includes:
- a cell assembly including a plurality of battery cells;
- a module housing having an arrangement space for accommodating the cell assembly and a cover plate covering a top surface of the cell assembly;
- and
- a blocking member disposed between the top surface of the cell assembly and the cover plate,
- wherein the cover plate has at least one discharge hole for discharging gas generated in the cell assembly,
- wherein the cover case has at least one guide groove to form a flow space in which the gas discharged through the at least one discharge hole flows, and
- wherein the gas flowing through the flow space is discharged externally through a venting unit provided in the pack case,
- wherein the venting unit is disposed on a side wall of the pack case, and a flow guide member is disposed between the battery module and the venting unit and the flow guide member guides the gas flowing through the flow space formed by the guide groove to be discharged through the venting unit,
- wherein the flow guide member has a guide portion disposed to be spaced apart from an inner surface of the side wall of the pack case such that the gas is guided to flow along the inner surface of the side wall of the pack case and then to be discharged through the venting unit, and a blocking portion extending from the guide portion toward the inner surface of the side wall of the pack case to block a space between the venting unit and a bottom surface of the bottom case.
