Battery module having attachment members between battery cells

Abstract

Disclosed herein is a battery module constructed in a structure in which a plurality of plate-shaped battery cells are stacked one on another. The battery module has attachment members interposed between the battery cells to prevent the battery cells from sliding due to external impacts and also to absorb the external impacts. The battery cells are securely attached to each other by the coupling between the attachment members, such as female- and male-type Velcro tapes. Consequently, the sliding of the battery cells due to external impacts is effectively prevented. Also, the female- and male-type Velcro tapes are elastically deformed, when the external impacts are applied to the battery cells, to absorb the external impacts. In addition, it is possible for a coolant, such as air, to pass through the coupled Velcro tapes by virtue of the structural characteristics of the female- and male-type Velcro tapes. Consequently, the cooling efficiency of the battery module is improved. Furthermore, the long-term use of the female- and male-type Velcro tapes is secured without the reduction of the attachment strength thereof, and therefore, the stacked structure of the battery module is stably maintained.

Description

technical field [0001] The present invention relates to a battery module having an attachment member between battery cells, and more particularly to a battery module configured in a structure in which a plurality of plate-shaped battery cells are stacked on each other with the attachment member Placed between the battery cells to prevent the battery cells from sliding due to external shocks and also absorb such external shocks. Background technique [0002] Recently, secondary batteries that can be charged and discharged have been widely used as power sources for wireless mobile devices. Moreover, electric vehicles (EV) and hybrid electric vehicles (HEV) have been developed to solve problems such as air pollution caused by existing gasoline and diesel vehicles using chemical fuels, secondary batteries as Electric vehicle (EV) and hybrid electric vehicle (HEV) power sources have attracted considerable attention. [0003] Each small-sized mobile device uses one or several sm...

AI Technical Summary

Problems solved by technology

As a result, the stacked structure of battery cells cannot be maintained

In particular, it also limits the use of attachment parts in medium-sized or large-sized battery modules used as power sources for electric vehicles and hybrid electric vehicles (the service life of which must be guaranteed for more than ten years or more)
