Abstract

Disclosed herein is a middle- or large-sized battery pack comprising a battery module including a plurality of unit modules horizontally stacked while each unit module is vertically erected on one side, the battery module being mounted in a sealed space of a housing member, wherein the housing member is provided at the upper or lower end of one side thereof with a coolant inlet port and at the lower or upper end of the opposite side thereof with a coolant outlet port, the battery module is mounted in the housing member such that the upper or lower end surface of the battery module is tilted toward the coolant inlet port by a predetermined angle, whereby a coolant introduced through the coolant inlet port in parallel with the battery module passes perpendicularly through the unit modules and is then discharged to the opposite side, and gaps (vertical flow channels) defined between the unit modules at the tilted upper or lower end surface of the battery module are arranged in parallel with the direction in which the coolant is introduced, whereby the cooling efficiency and the cooling uniformity of the battery pack are improved while the battery pack has a compact structure.

Description

technical field [0001] The present invention relates to a medium or large battery pack with high cooling efficiency, and more specifically, relates to a medium or large battery pack comprising: a battery module including a plurality of unit modules, the units The modules are stacked horizontally while each unit module is vertically erected on one side, the battery module is fixed in a sealed space of a housing member provided with a coolant inlet port at an upper end or a lower end of one side thereof and Coolant outlet ports are provided at upper or lower ends on opposite sides thereof, and the battery module is fixed in the case member such that the upper or lower end surface of the battery module is inclined toward the coolant inlet port at a predetermined angle, thereby making the The coolant introduced through the coolant inlet port parallel to the battery module passes through the unit module vertically and then is discharged to the opposite side; The upper or lower end...
