A battery module includes a battery cell assembly having a plurality of battery cells stacked on each other, a pair of end plates provided at both sides of the battery cell assembly; and a cover frame coupled to the pair of end plates to cover the battery cell assembly, the cover frame being deformed along an inflating direction of the plurality of battery cells when the plurality of battery cells are inflated.

Battery module and battery pack comprising battery module

An Energy Storage System (ESS) module includes a cell stack assembly including a cell stack formed by stacking a plurality of battery cells and a plurality of mica barrier assemblies and a pair of bus bar frames coupled to both side portions of the cell stack; and a housing configured to accommodate the cell stack assembly and having a plurality of flow path holes formed at locations corresponding to a front side, a rear side and both side portions of the cell stack assembly, wherein the mica barrier assembly is provided between adjacent battery cells and at an outermost side of the cell stack to form a flow path along a stacking direction of the cell stack at a temperature lower than a reference temperature and to block the flow path at a temperature equal to or higher than the reference temperature.

ESS module having structure capable of preventing external exposure of flame and ESS pack including the same

A battery module includes: a unit module stack formed by stacking a plurality of unit modules, each of which has a battery cell, a bus bar attached to an electrode lead provided to the battery cell, and a bus bar frame attached to a terrace portion of the battery cell to accommodate at least a portion of the electrode lead and the bus bar, wherein each bus bar frame includes a connector holder; and a connector fixed by the connector holders of at least two unit modules of the plurality of unit modules to contact the bus bar.

Battery module having structure facilitating series-parallel connections and battery pack comprising same

Disclosed is a battery module, which includes a plurality of battery cells disposed to face each other and arranged side by side at least in a first direction, a module cover configured to accommodate the plurality of battery cells and formed to have at least one open side, and a pair of buffering members located between one side of a battery cell located at an outermost side in the first direction among the plurality of battery cells and a side of the module cover so that at least a part thereof is in contact with the sides of the battery cells and the module cover, respectively, wherein the buffering member is a leaf spring having at least one bent portion.

Battery module, and battery pack and vehicle comprising the same

A unit module includes: a battery cell having an electrode assembly, a cell case for accommodating the electrode assembly, and an electrode lead connected to the electrode assembly and drawn out of the cell case; a bus bar attached to the electrode lead; and a bus bar frame attached to a terrace portion of the battery cell to accommodate at least a portion of the electrode lead and the bus bar therein, the bus bar frame pressing the electrode lead and the bus bar so that the electrode lead and the bus bar are adhered to each other, the bus bar frame having a welding slit formed at a location corresponding to the bus bar and the electrode lead so that a contact portion of the bus bar and the electrode lead is exposed out of the bus bar frame.

Unit module including busbar frame structure which can facilitate welding, and battery module including same

Disclosed is a battery housing. The battery housing includes a plurality of covers coupled to each other to form a space in which the battery is accommodated, the plurality of covers having a first cover and a second cover disposed adjacent to the first cover and coupled to the first cover; and a coupling rod configured to couple the first cover and the second cover.

Battery housing and battery module comprising same

A battery module including an array of cooling fins having different thicknesses is provided. The battery module includes: a plurality of battery units arranged in one direction; a plurality of cooling fins between adjacent battery units; and a heat sink coupled to ends of the plurality of cooling fins, wherein each cooling fin has a structure in which a pair of sub-cooling fins are face-to-face coupled to each other, and thicknesses of the plurality of cooling fins are reduced toward the side region from the central region due to a difference in a thickness of at least one of the pair of sub-cooling fins. Since heat is not accumulated at the central region, the battery module has uniform temperature distribution while being charged or discharged.
