Abstract

The present invention is directed to a busbar (50) for connecting cell terminals (11, 12) of at least two battery cells (10) of a battery module (90), and the battery module comprising such busbar. The busbar (50) comprising a first contact portion (21) configured to connect to a first cell terminal (11), a second contact portion (22) configured to connect to a second cell terminal (12), and an arced portion (30) configured to connect the first contact portion (21) and the second contact portion (22). The contact portions (21, 22) extend in a first plane and the arced portion (30) extend in asecond plane essentially perpendicular to the first plane. Further, a first bent portion (41) extends from the first contact portion (21) into the second plane and connects the first contact portion (21) and the arced portion (30) and a second bent portion (42) extends from the second contact portion (22) in the second plane and connects the second contact portion (22) and the arced portion (30).

Description

technical field [0001] The present invention relates to bus bars for battery modules, in particular, low height flexible bus bars for compact battery modules. The invention also relates to battery modules, in particular to battery modules comprising such low height and flexible bus bars. Background technique [0002] A rechargeable or secondary battery differs from a primary battery in that it can be repeatedly charged and discharged, whereas a primary battery only provides an irreversible conversion of chemical energy into electrical energy. Low-capacity rechargeable batteries are used as power sources for small electronic devices such as cellular phones, notebook computers, and camcorders, while high-capacity rechargeable batteries are used as power sources for electric vehicles or hybrid vehicles, and the like. [0003] In general, a rechargeable battery includes: an electrode assembly including a positive electrode, a negative electrode, and a separator interposed betwe...
