Abstract

A battery module of the present invention includes a plurality of unit batteries and a connection member electrically connecting the plurality of unit batteries. The connection member includes: a plurality of bus bars, each of the plurality of bus bar having two through-holes respectively corresponding to two electrode terminals protruding from two adjacent unit batteries of the plurality of unit batteries; and an insulating guide having a plurality of holder units configured to support the plurality of bus bars, and a plurality of narrow width portions positioned between the plurality of holder units and connecting the plurality of holder units along a first direction.

Description

technical field [0001] The following description relates to a battery module including a plurality of unit cells coupled by connection members. Background technique [0002] The battery module is a module including a plurality of unit cells connected in series to realize high power and large capacity. The rechargeable battery module is used as a power source of equipment requiring a large capacity, such as an electric motor for driving an electric vehicle or a hybrid vehicle. The unit battery may be a rechargeable battery capable of being recharged. Recently, high-power rechargeable batteries using non-aqueous electrolytes having high energy density have been developed. [0003] A positive terminal and a negative terminal protrude from each unit cell, and a plurality of unit cells are alternately arranged such that positions of the positive terminal and the negative terminal are opposed to each other. The battery module includes connection members so that the unit cells a...
