Patent number: 10476058Abstract: A battery module is disclosed. In one aspect, the battery module includes first through third battery packs electrically connected to one another. The battery module also includes a bus pattern. The bus pattern includes i) a main body including an input/output point of a charging/discharging path and ii) first through third branching portions that branch from the main body and extend to first through third contact points of the first through third battery packs, respectively. A first distance is defined as the distance between the input/output point and the first contact point, a second distance is defined as the distance between the input/output point and the second contact point and a third distance is defined as the distance between the input/output point and the third contact point. The first distance is less than the second distance, and the second distance is less than the third distance.Type: GrantFiled: April 28, 2016Date of Patent: November 12, 2019Assignee: Samsung SDI Co., Ltd.Inventors: Junseop Kim, Daepyo Lee, Donghyun Kim, Heesung Jung
