A battery module includes a plurality of battery cells assemblies, each having a plurality of battery cells stacked on each other; and at least one cooling unit provided between the plurality of battery cells assemblies and filled with a predetermined coolant therein, the at least one cooling unit having at least one membrane member provided at one end thereof to be opened or closed according to a change of an internal pressure thereof.

Battery module, and battery pack and power storage device including same

Disclosed is a cooling jacket configured to be disposed close to one surface of a battery cell to absorb heat of the battery cell, the cooling jacket including a cooling plate and a plurality of cooling channels extending therein. The plurality of cooling channels include a coolant supply manifold channel and a coolant discharge manifold channel respectively disposed at first and second sides of the cooling plate and each extending in a longitudinal direction from an inside of the cooling plate to an outside of the cooling plate so that one end thereof is exposed to the outside of the cooling plate; and non-uniform cooling channels spaced apart from each other by a predetermined distance and each having first and second ends respectively connected to the coolant supply manifold channel and the coolant discharge manifold channel, the non-uniform cooling channels having widths that are non-uniform in the longitudinal direction.

Cooling jacket having nonuniform flow paths, for cooling battery cell surface, and battery module including same

A battery module including a battery-cooling heat sink having a PCM capsule. The battery-cooling heat sink provides a uniform temperature of a cooling fluid flowing through the battery module using a PCM capsule, minimizes a temperature variation of the cooling fluid over the entire area of the heat sink formed in the battery module, and prevents the temperature at a cooling fluid outlet of the heat sink from being higher than that of a cooling fluid inlet.

Battery-cooling heat sink provided with PCM capsule

Disclosed is a battery module, which includes a battery cell assembly including a plurality of battery cells stacked on each other along a vertical direction, a heatsink configured to cover one side of the battery cell assembly, and a pair of cooling plates connected to the heatsink to cover both side surfaces of the battery cell assembly, respectively, the pair of cooling plates having a coolant channel formed along a stacking direction of the plurality of battery cells.
