본 고안은 전동 지게차 등에 사용되는 배터리에 관한 것으로, 더욱 상세하게는 저온 또는 고온에 효율성 있게 동작할 수 있도록 배터리 하우징내에 유입되늰 외기의 온도를 조절하는 장치를 구비한 배터리에 관한 것이다.The present invention relates to a battery used in an electric forklift, and more particularly, to a battery having a device for adjusting the temperature of the outside air introduced into the battery housing to operate efficiently at low or high temperatures.

종래의 배터리는 이 배터리가 장착된 기구의 외부온도변화에 의한 일어날 수 있는 효율저하를 방지하는 장치가 전혀 구비되어 있지 않았다. 따라서, 배터리를 사용하는 지게차가 저온창고(0℃ -30℃)에서 장시간 작업을 수행하는 경우 제1도에 도시돤 봐와 같이 그 효율이 현저히 저하되어 1회 충전당 최대 작업시간이 짧아지는 문제점이 있었다. 일예로 500AH의 용량을 가진 배터리로 표준작업시간 5시간을 사용하는 지게차가 -15℃의 저온창고에서 계속 작업을 수행하는 경우, 배터리 효율은 약 50%로 떨어져 실제 작업시간은 약 2시간 30분밖에 되지 않는다. 반대로, 고온에서 장시간의 작업을 수행할 경우 효율자체는 문제점이 없지만 제2도에 도시된 바와 같이 축전지 수명시간은 40℃를 기점으로 하여 급격히 떨어진다. 이런 현상은 배터리 방전에 의한 자체 발병 때문에 외기 온도보다 상승할 수도 있기 때문에 흔히 발생된다.Conventional batteries are not equipped at all with a device that prevents the efficiency degradation that may occur due to a change in external temperature of a device equipped with the battery. Therefore, when a forklift using a battery works for a long time in a low temperature warehouse (0 ° C -30 ° C), as shown in FIG. 1, the efficiency is significantly lowered, resulting in a shorter maximum work time per charge. There was this. For example, if a forklift truck that uses a standard working time of 5 hours with a battery having a capacity of 500 AH continues to work at a low temperature warehouse of -15 ° C, the battery efficiency drops to about 50% and the actual working time is about 2 hours 30 minutes. It is only. On the contrary, when the long time operation is performed at a high temperature, the efficiency itself does not have a problem, but as shown in FIG. 2, the battery life time drops sharply from 40 ° C. This often occurs because the temperature may rise above ambient temperature due to self-onset by battery discharge.

본 고안은 전술한 문제점을 해결하기 위한 것으로서, 그 목적은 배터리의 사용온도변화에 따른 효율감고 및 수명감소를 제거한 배터리를 제공함에 있다.The present invention is to solve the above-mentioned problems, the object of the present invention is to provide a battery in which the efficiency reduction and life reduction according to the use temperature of the battery is removed.

전술한 목적을 달성하기 위하여 본 고안의 배터리는 복수의 배터리 셀이 하우징내에 내장된 배터리에 적용되며, 상기 하우징내의 소정위치에 형성되어 상기 각 셀들의 사이공간과 연통되고, 외부와 연통된 적어도 하나 이상의 송풍구가 형성된 에어덕트, 상기 송풍구를 통해 상기 에어턱트내로 유입된 공기를 가열하는 수단을 구비하여 가열된 공기가 상기 에어덕트와 상기 각 셀들의 사이공간을 수환한 후 외부로 배출되게 구성된 것을 특징으로 한다.In order to achieve the above object, the battery of the present invention is applied to a battery in which a plurality of battery cells are built in a housing, and formed at a predetermined position in the housing to communicate with the interspace of each of the cells, and at least one communicated with the outside And a means for heating the air introduced into the air duct through the air outlet, the air duct having the above-described air outlet is configured to be discharged to the outside after receiving the space between the air duct and the respective cells. It is done.

이하, 본 고안에 따른 배터리의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of a battery according to the present invention will be described in detail with reference to the accompanying drawings.

제3도 및 제4도는 본 고안의 코일 및 히터작동 온도범위를 나타낸 그래프이다. 도면에서 알 수 있는 바와 같이, 본 고안의 배터리의 하우징(10)내에 장착된 배터리 일정온도 유지수단은 외부온도변화에 따라 적절히 동작한다. 즉, -40℃ 정도일 경우에는 온도를 높이도록 히터코일(5)이 작동하며, 20℃이하 또는 40℃이상에서도 히터코일(5)은 동작되지 않고 팬(4)만 작동된다. 따라서, 항상 최적조건을 유지함으로써 배터리의 효율 및 사용시간이 증대된다.3 and 4 are graphs showing the coil and heater operating temperature range of the present invention. As can be seen in the figure, the battery constant temperature maintaining means mounted in the housing 10 of the battery of the present invention operates properly according to the external temperature change. That is, in the case of about -40 ° C, the heater coil 5 is operated to increase the temperature, and the heater coil 5 is not operated at only 20 ° C or lower or 40 ° C or higher, and only the fan 4 is operated. Therefore, by maintaining optimum conditions at all times, the efficiency and use time of the battery are increased.

이하, 배터리 하우징(10)내의 에어덕트(1)에 배치된 일정온도 유지 수단에 대한 작동을 설명한다.Hereinafter, the operation of the constant temperature maintaining means arranged in the air duct 1 in the battery housing 10 will be described.

제5도(a) 및 (b)는 각각 배터리 내부투시도 및 단면도를 나타낸 도면이고, 제6도는 제5도의 에어덕트의 상세도이다. 제5도 및 제6도에서, 기존의 배터리 하우징의 하부에 구획 칸막이(9)를 설치하여 에어덕트(1)를 형성하였다.5 (a) and (b) show a perspective view and a cross-sectional view of the battery, respectively, and FIG. 6 is a detailed view of the air duct of FIG. 5 and 6, the air divider 1 is formed by installing a partition divider 9 under the existing battery housing.

각 배터리 셀(3)사이에 공기의 흐름이 가능토록 홀(2)를 뚫는다.Holes 2 are drilled to allow air to flow between each battery cell 3.

또한, 배터리 하우징(10)의 하부에 4개의 송풍구(8)를 뚫고, 그 각각의 내부에 히터코일(5)과 팬(4)을 설치하고, 적어도 3곳 이상의 배터리 셀(3)내부에 온도센서(6)를 설치하여, 배터리의 온도가 20℃이하로 냉각되었을 때 히터코일(5)을 작동시킴과 동시에 팬(4)을 작동시킴으로써 에어덕트(1)로 흡입된 가열된 공기가 각 배터리셀(3)사이에 뚫어놓은 홀(2)을 통하여 상부로 흐르게 된다.In addition, four air vents 8 are drilled in the lower part of the battery housing 10, and heater coils 5 and a fan 4 are installed in each of them, and at least three or more battery cells 3 are provided with a temperature. By installing the sensor 6, the heated air sucked into the air duct 1 by operating the fan coil 4 and the fan 4 at the same time when the temperature of the battery is cooled to 20 ° C. or lower, It flows upward through the holes 2 drilled between the cells 3.

따라서, 배터리의 효율을 떨어뜨리는 냉각을 방지할 수 있게 된다.Therefore, it is possible to prevent cooling that lowers the efficiency of the battery.

이 때 히터코일(5)에 흐르는 전류 IR은 전술한 제3도에 도시된 바와 같이 20℃에서 -40℃까지 온도가 낮을수록 많이 흐르게 되는데, 이는 주울의 법칙(H= 0.24I2Rt)에 따라 다른 조건이 동일할 때 전류의 제곱에 비례하여 히터코일의 온도가 상승하는 원리를 이용한 것이다.At this time, the current I R flowing through the heating coil 5 is flowing there is a lot lower the temperature at 20 ℃ to -40 ℃ as illustrated in the aforementioned FIG. 3, which Joule's law (H = 2 Rt 0.24I) When the other conditions are the same, the heater coil temperature is increased in proportion to the square of the current.

반편, 배터리 온도가 상승하여 40℃이상이 되면, 제3도 및 제4도에서 알 수 있는 바와 같이 히터코일(5)은 작동하지 아니하고 팬(4)만 작동하여, 외기가 에어덕트(1)로 흡입된다. 이 흡입된 공기는 전술한 바와 같이 홀(2)을 따라 흐름으로써, 배터리 사용에 따른 자체 발열로 인한 과열이 방지된다.On the other hand, when the battery temperature rises to 40 ° C. or higher, as shown in FIGS. 3 and 4, the heater coil 5 is not operated but only the fan 4 is operated. Is inhaled. As the sucked air flows along the hole 2 as described above, overheating due to self-heating due to battery use is prevented.

이상 설명한 바와 같이, 본 고안에 따른 배터리는 외부온도에 따라 적절히 대응할 수 있어 그 효율성 및 수명이 증대되고, 그에 따라 이 배터리를 장착해야하는 작업기구의 작업효율성을 높일 수 있으며, 아울러 배터리 자체의 안정성도 확보되는 이점이 있다.As described above, the battery according to the present invention can respond appropriately according to the external temperature, and its efficiency and lifespan are increased, thereby increasing the work efficiency of the work tool to which the battery is mounted, and also the stability of the battery itself. There is an advantage to be secured.
