Abstract

The invention disclose a battery module having a holder. The battery module includes a plurality of rechargeable batteries having a terminal, a holder combined to end portions of the rechargeable batteries and having a first fastening portion, and a bus bar combined to the terminal, electrically connecting the rechargeable batteries, and having a second fastening portion to be fitted into the first fastening portion.

Description

technical field [0001] The described technology relates generally to battery modules. More specifically, the described technology relates generally to battery modules having improved holder structures to support rechargeable batteries. Background technique [0002] A rechargeable battery differs from a primary battery in that it can be repeatedly charged and discharged, whereas the latter cannot be recharged. [0003] Low-capacity rechargeable batteries are used in small portable electronic devices such as mobile phones, notebook computers, and camcorders, while high-capacity rechargeable batteries can be widely used as motors for driving hybrid vehicles, electric vehicles, etc. power supply. [0004] In addition, high-capacity battery modules generally include a plurality of rechargeable batteries connected in series, and the rechargeable batteries may be formed in a cylindrical or prismatic shape. [0005] The battery modules are provided with bus bars to electrically c...
