Problems solved by technology

However, methods of using cooled battery cells or providing active cooling to control the temperature of the electrical interconnection area are not space or cost efficient.
[0013] In addition, a conventional medium or large battery module used as a power source of a hybrid electric vehicle briefly uses a high current
However, the internal combustion engine is the main power source, and the battery module is the auxiliary power source, as a result, the use time at high current is very short, and thus does not generate enough heat to affect the battery cells
Therefore, additional structures or methods for cooling the electrical interconnection area are not considered

Embodiment Construction

[0087] Now, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted, however, that the scope of the present invention is not limited by the illustrated embodiments.

[0088] figure 1 is a perspective view illustrating a battery module according to an embodiment of the present invention, and figure 2 is a gesture figure 1 Typical view of a heat sink.

[0089] Referring to these drawings, the battery module 100 includes a unit module stack 120 including four unit modules 122 that are stacked in a lateral direction thereof and that can be charged and discharged and connected to electrical terminals between the unit modules 122. The area 130 is connected to the heat sink 110 that absorbs heat generated from the unit module 122 during charging and discharging of the unit module 122 .

[0090] The heat sink 110 includes three bar-type contact parts 112 configured to be in close contact with the o...

Abstract

The present invention provides a battery module, in which multiple battery cells or unit modules ('unit cells') are accumulated, and heat sinks for absorbing heat generated from the unit cells are mounted on an electric connecting part of the unit cells and / or on the outer side of a battery module connection member that is connected to the electric connecting part.

Description

technical field [0001] This application claims priority and benefits from Korean Patent Application No. 2009-0027934 filed on Apr. 1, 2009 at the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference. [0002] The present invention relates to a battery module with improved safety, and more particularly to a battery module configured in a structure in which a plurality of battery cells or unit modules ("unit cells") are stacked , and the heat sink is installed to the electrical connection area between the unit cells and / or is installed to the outside of the battery module connection part connected to the electrical connection area. Background technique [0003] Recently, secondary batteries capable of being charged and discharged have been widely used as energy sources for wireless mobile devices. Also, secondary batteries have attracted considerable attention as power sources for electric vehicles (EV), hybrid electric vehicles (HE...
