Embodiment Construction

[0027] In the following description, although air is used as an example of the cooling medium (coolant) of the battery module, the present invention is not limited thereto, for example, water or other fluids may be used as the cooling medium.

[0028] refer to figure 1 , The battery module 10 of the present embodiment includes: a battery assembly 11 having a plurality of unit cells 12 arranged at predetermined intervals;

[0029] Each of the unit batteries 12 is a conventional rechargeable battery for charging and discharging predetermined electric power. That is, the unit cell 12 includes an electrode assembly having a positive electrode and a negative electrode and a separator interposed therebetween.

[0030] The battery pack 11 is a structure formed of a plurality of unit cells 12 spaced apart from each other in a straight line.

[0031] According to the present embodiment, the battery pack 11 is preferably formed by stacking a plurality of prismatic unit cells 12 .

Abstract

Provided is a secondary battery module which is improved in the temperature control efficiency of unit battery by modifying the circulation structure of cooling medium and is minimized in the temperature deviation of unit batteries. The secondary battery module(10) comprises at least one battery assembly(11) which comprises a layered unit batteries(12); a housing(20) which accommodates the battery assembly and circulates the cooling medium for the control of temperature; and an inducing member(30) which is installed on the propagation passage(23,24) of the cooling medium formed along the housing and is toward the inlet(21) of cooling medium at the end part of the passage. Preferably the front end toward the inlet of cooling medium of the inducing member has a wedge form.

Description

technical field [0001] The present invention relates to a battery module in which cooling efficiency of unit cells is improved. Background technique [0002] Unlike primary batteries, rechargeable batteries can be recharged. Low power batteries are used in various portable electronic devices, for example, in phones, laptop computers and camcorders. A bulk size battery is used as a power source for driving a motor, for example, as a power source in a hybrid car. [0003] Secondary batteries can be classified into different types according to their appearance, for example, prismatic batteries and cylindrical batteries. Secondary batteries may be formed as high-power rechargeable battery modules when they are used to drive motors of machines requiring high power sources, such as those driving hybrid vehicles. [0004] A rechargeable battery module is formed by successively connecting several secondary batteries (hereinafter, "unit cells"). [0005] Each of the unit cells in...
