The present invention relates to a battery pack having a cooling unit provided outside a pack case, and more particularly a battery pack including a battery module () including one or more unit cells; a case () having a receiving portion configured to receive the battery module (); a cooling unit () located at an outer bottom surface of the case (); and a reinforcement member () configured to protect the cooling unit ().

Battery pack having cooling unit provided outside case

A battery pack includes: a lower case and an upper case; and an annular gasket formed between the lower case and the upper case to seal between the cases, wherein the gasket includes first and second sealing parts connected to each other, and wherein a melting point of the second sealing part is lower than the melting point of the first sealing part.

Battery pack and device including the same

A cooling member for a battery module, and a battery pack including the same, according to an exemplary embodiment of the present invention includes: a cooling plate including an upper plate and a lower plate; and a supporter disposed between the upper plate and the lower plate, the supporter defining a plurality of refrigerant flow paths. The lower plate has a refrigerant inflow part and a refrigerant outflow part, and a reinforcing member is formed adjacent to at least one of the refrigerant inflow part and the refrigerant outflow part.

Cooling member for battery module and battery pack including the same

Disclosed herein is a battery pack case configured to receive a battery module assembly including a plurality of battery modules, each having a plurality of battery cells or unit modules mounted therein, sequentially stacked, wherein a coolant inlet port and a coolant outlet port are located at the upper part and the lower part of the battery pack case, respectively, in a state in which the coolant inlet port and the coolant outlet port are opposite to each other such that a coolant for cooling the unit modules flows from one side of the battery modules to the opposite side of the battery modules in a direction perpendicular to a direction in which the unit modules are stacked, and an inclined plate for guiding the flow of the coolant is provided between the battery pack case and the battery modules.

Battery pack case having efficient cooling structure

Disclosed is a battery module including a battery cell stack including a structure in which a plurality of battery cells connected to each other in series and/or in parallel is stacked and each of the battery cells is stood on one side thereof, voltage sensing members provided with connecting terminals electrically connected to electrode terminal connection parts of the battery cells for detecting voltages of the battery cells, an upper case covering the end of one side of the battery cell stack and portions of upper and lower ends of the battery cell stack, the upper case being provided with mounting parts, into which the voltage sensing members are inserted and mounted, and a lower case coupled to the upper case while covering the end of the other side of the battery cell stack and portions of the upper and lower ends of the battery cell stack.
