Problems solved by technology

However, there is a problem in that the cooling efficiency of the unit cells is reduced, and a temperature difference is caused, resulting in uneven cooling
[0010] According to this, if the battery rows are arranged side by side, since the heat generated by each unit cell in the battery row cannot be uniformly dissipated, the performance of the unit cells themselves will be degraded, so this secondary battery module cannot be used as a motor that requires high power. drive

Embodiment Construction

[0041] Embodiments of the present invention will now be described in detail with reference to examples illustrated by the accompanying drawings. The following description explains the embodiments by referring to the figures to explain the present invention.

[0042] figure 1 is a schematic perspective view of the secondary battery module of the first embodiment of the present invention, figure 2 yes figure 1 cross-sectional plan of the .

[0043] Referring to these drawings, a secondary battery module 10 includes a battery aggregate 11 having a plurality of unit cells 12 arranged continuously at predetermined distances, and a case 20 accommodating the battery aggregate 11 . A cooling medium for controlling the temperature of the unit cells 12 circulates inside the housing 20, and cooling air, cooling water, other cooling fluids, etc. may be used as the cooling medium.

[0044] In this embodiment, air (hereinafter referred to as "cooling air") that can be conveniently obta...

Abstract

The present invention relates to a secondary battery module including at least more than two battery aggregates having a plurality of unit batteries continuously arranged, and a housing receiving the battery aggregates, wherein, with respect to the arrangement direction of the unit batteries, each of the unit batteries of each of the battery aggregates is disposed in an oblique direction against the arrangement direction of the unit batteries. The present invention minimizing the size and preventing the heat unbalance caused by partly cooling cell batteries in the batteries congeries by improving the arranging structure of the cell batteries in the housing. So the present invention makes the efficiency of the cooling cell battery highest to improve the charging and discharging efficiency more.

Description

technical field [0001] The present invention relates to a secondary battery module, in particular to an improved unit battery arrangement structure for the secondary battery module. Background technique [0002] Unlike primary batteries, secondary batteries can be recharged. Low power batteries are used in a variety of portable electronic devices such as cellular phones, laptop computers, and camcorders. Large-capacity bulk size batteries are used, for example, as motor drive power sources in fuel-electric vehicles. [0003] Secondary batteries can be classified into different types according to their shapes, such as square batteries and cylindrical batteries. If they are used to drive a mechanical motor that requires a high-power power supply, such as a fuel-electric dual-purpose vehicle, the secondary battery (hereinafter referred to as "unit battery") can form a high-power secondary battery module. [0004] When the secondary battery module is used as a motor drive for...
