다음은 본 고안인 면상발열체가 구비된 배터리 모듈의 바람직한 실시예를 첨부한 도면을 기초로 상세하게 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a battery module including a planar heating element will be described in detail with reference to the accompanying drawings.

본 고안인 면상발열체가 구비된 배터리 모듈은 특히 중계기용 배터리 모듈에 관한 것으로서, 면상발열체가 구비된 중계기용 배터리 모듈인 것을 특징으로 한다.The battery module including the planar heating element is particularly a relay battery module, and is a battery module for a repeater equipped with a planar heating element.

도시된 바와 같이, 본 고안의 일 실시예에 의한 면상발열체가 구비된 배터리 모듈은, 기기(10)에 전원을 공급하는 2차전지인 배터리팩(110)과, 상기 배터리팩(110)에 열을 공급하여서 배터리팩(110)이 영하에서도 용량(capacity)의 저하를 방지하기 위한 면상발열체(120)와, 상기 면상발열체(120)와 배터리팩(110) 사이에 연결되어서 스위칭 제어신호에 따라서 스위칭 온오프하여서 면상발열체의 동작을 제어하는 스위치(130)를 포함하여 구성되는 것을 특징으로 한다.As shown in the drawings, a battery module including the planar heating element according to an embodiment of the present invention includes a battery pack 110 as a secondary battery for supplying power to the device 10, A surface heating element 120 for preventing the capacity of the battery pack 110 from being lowered even when the battery pack 110 is kept at a low temperature and a switching power supply 120 connected between the surface heating element 120 and the battery pack 110, And a switch (130) for controlling the operation of the surface heat emission element by turning off.

이에 의하면, 배터리가 영하에서는 면상발열체에 의한 열을 공급받아서 용량이 저하되는 것을 방지할 수 있는 이점이 있다.According to this, there is an advantage that the capacity can be prevented from being lowered by receiving heat from the planar heat generating element at a low temperature of the battery.

그리고, 스위치가 동작시에만 면상발열체가 동작하게 된다.Then, the surface heat emission element operates only when the switch is operated.

본 고안의 일 실시예에 의한 면상발열체가 구비된 배터리 모듈에 있어서, 상기 면상발열체는 면상발열시트로 구성되는 것을 특징으로 하고, 상기 면상발열시트는 상기 배터리팩과 면접촉하여서 구비되는 것을 특징으로 한다.In the battery module having the planar heating element according to one embodiment of the present invention, the planar heating element is formed of a planar heating sheet, and the planar heating sheet is provided in surface contact with the battery pack do.

상기 배터리팩은 2차 전지로서 예컨대 리튬이온, 리튬폴리머 리튬인산철 배터리가 될 수 있다.The battery pack may be, for example, a lithium ion or a lithium polymer lithium iron phosphate battery as a secondary battery.

상기 기기(10)는 전기전자통신 기기인 것으로서 바람직하게는 중계기이고, 상기 배터리팩은 중계기용 배터리팩인 것을 특징으로 한다.The device 10 is an electric / electronic communication device, preferably a repeater, and the battery pack is a battery pack for a repeater.

본 고안의 일 실시예에 의한 면상발열체가 구비된 배터리 모듈에 있어서, 상기 배터리팩(110)에 구비되어서 배터리팩(110)의 온도를 검출하는 온도센서(140)가 더 포함되어서 구성되고, 상기 온도센서(140)에서 검출된 온도가 기 설정된 기준 온도 이하인 경우에는 상기 스위치(150)로 스위칭 온 제어신호를 출력하는 제어부(150)가 더 포함되어서 구성되는 것을 특징으로 한다.The battery module according to one embodiment of the present invention may further include a temperature sensor 140 provided in the battery pack 110 to detect the temperature of the battery pack 110, And a control unit 150 for outputting a switching-on control signal to the switch 150 when the temperature detected by the temperature sensor 140 is lower than a preset reference temperature.

이에 의하면, 온도를 검출하여서 설정된 온도 예컨대 영하에서만 동작하도록 함으로써, 자가 방전의 최소화를 구현할 수 있어서 발열에 의한 전력 소비를 줄일 수 있는 이점이 있다.According to this, by detecting the temperature and operating only at a set temperature, for example, at a sub-zero temperature, it is possible to minimize the self-discharge, thereby reducing power consumption due to heat generation.

그리고, 배터리가 동작하지 않고 단순 보관시에는 면상발열체가 동작되지 않게 되는 이점이 있다.In addition, when the battery is not operated and stored in a simple manner, the surface heating element is not operated.

이 실시예의 경우에는 스위치가 별도로 없고, 단자를 연결하면 자동으로 전력이 공급되는 것을 특징으로 한다.In this embodiment, no switch is provided, and power is automatically supplied when a terminal is connected.

이와 같이 본 고안에 따른 바람직한 실시예를 살펴보았으며, 앞서 설명된 실시예 이외에도 본 고안이 그 취지나 범주에서 벗어남이 없이 다른 특정 형태로 구체화될 수 있다는 사실은 해당 기술분야에 있어 통상의 지식을 가진 자에게는 자명한 것이다.It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions.
