By a News Reporter-Staff News Editor at Journal of Engineering -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Lee, Hyun-Ye (Yongin-si, KR); Kim, Tae-Young (Yongin-si, KR); Kim, Myung-Chul (Yongin-si, KR); Park, Shi-Dong (Yongin-si, KR), filed on November 2, 2010, was published online on April 19, 2016.

The patent's assignee for patent number 9318731 is SAMSUNG SDI CO., LTD. (Yongin-si, Gyeonggi-do, KR).

News editors obtained the following quote from the background information supplied by the inventors: "Embodiments relate to a battery pack.

"As the number of gasoline vehicles has increased, the amount of vehicle exhaust emission has also increased. Vehicle exhaust emission includes large amounts of harmful substances, such as nitrogen oxide due to combustion, carbon monoxide or hydrocarbon due to imperfect combustion, or the like, and is recognized as a serious environmental pollution problem. As fossil fuels are anticipated to be significantly diminished in the not too distant future, development of next generation energy sources and hybrid electric vehicles have become important issues. In terms of commercializing hybrid electric vehicles, mileage of such vehicles is determined by battery performance. Currently, however, batteries do not have enough electrical energy for powering hybrid electric vehicles for a desirable period of time or mileage. If vehicles use energy sources such as gasoline, light oil, gas, or the like, the vehicles may quickly refuel in filling stations or gas charging stations. However, even when an electric charging station is available, it takes a long time to charge a hybrid electric vehicle, which is an obstacle to commercialization. Thus, with regard to hybrid electric vehicles, improving battery performance, compared to other technologies regarding hybrid electric vehicles, is recognized as an important problem."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "It is a feature of an embodiment to provide a battery pack including a plurality of stacked battery modules each including secondary batteries, which prevents deviation of the secondary batteries by effectively supporting its weight and effectively emits gas, generated in the battery modules, to the outside.

"It is another feature of an embodiment to provide a battery pack that effectively emits gas, generated in the battery modules, to the outside.
