무선 충전을 통한 자기 방전을 방지하는 납축전지{Lead-acid battery to prevent self-discharge through wireless charging}Lead-acid battery to prevent self-discharge through wireless charging}

본 발명은 무선 충전을 통한 자기 방전을 방지하는 납축전지에 관한 것으로서, 더욱 상세하게는 무선충전수신부(150)가 형성되어 있는 자기방전방지수단(100)을 납축전지에 장착하여 장기간 차량 방치시, 무선충전송신장치를 통해 전류를 공급받아 납축전지를 충전시키는 무선 충전을 통한 자기 방전을 방지하는 납축전지에 관한 것이다.The present invention relates to a lead-acid battery that prevents self-discharge through wireless charging, and more particularly, when the self-discharge prevention means 100 in which the wireless charging receiver 150 is formed is mounted on a lead-acid battery and left in a vehicle for a long period of time, It relates to a lead-acid battery that prevents self-discharge through wireless charging, which charges the lead-acid battery by receiving current through a wireless charging and transmitting device.

일반적으로 배터리는 가솔린 자동차, 디젤 자동차 할 것 없이 모든 자동차에 설치되어 엔진을 기동할 때와 발전량이 부족할 때의 점화, 조명 등의 전원으로 사용된다.In general, batteries are installed in all cars, including gasoline and diesel cars, and are used as power sources such as ignition and lighting when starting an engine and when power generation is insufficient.

현재 자동차용으로 가장 많이 사용되는 납산 축전지(배터리)는 양극과 음극의 전극과 전해액으로 구성되어 있으며, 양 전극을 도체로 연결하여 각 전극의 작용 물질과 전해액이 가지는 화학적 에너지를 전기적 에너지로 끌어낼 수 있게 되어 있다.Lead acid accumulators (batteries), which are currently the most used for automobiles, are composed of positive and negative electrodes and an electrolyte, and by connecting both electrodes with a conductor, the chemical energy of each electrode and the electrolyte can be drawn out as electrical energy. It is supposed to be.

또한, 역으로 전기적 에너지를 주면 다시 화학적 에너지를 가진 본래의 작용 물질로 되돌아가도록 되어 있다.In addition, when electrical energy is applied in reverse, it is returned to the original working material with chemical energy.

그리하여 종래에는 공개실용신안공보 제1998-041499호(19980925 공개)를 통하여 배터리 전해액의 적정량을 확인할 수 있는 기술이 제안되었다. Thus, conventionally, a technology capable of confirming an appropriate amount of battery electrolyte has been proposed through Public Utility Model Publication No. 1998-041499 (published 19980925).

종래의 배터리검사장치는 배터리 내측에 전해액이 정상일 때 잠기고 부족할 때 전해액으로부터 노출되는 전해액레벨감지수단, 상기 전해액레벨감지수단에 따라 온오프되는 스위칭수단 및 경고등을 구비하여 배터리 전해액의 양이 적정한지를 확인하였다.A conventional battery inspection device includes a means for detecting an electrolyte level inside the battery that is immersed when the electrolyte is normal and exposed from the electrolyte when the electrolyte is insufficient, a switching means for turning on and off according to the electrolyte level detecting means, and a warning light to check whether the amount of the battery electrolyte is appropriate I did.

그리고, 최근 차세대 배터리로 리튬을 이용한 리튬이온 배터리 및 AGM 배터리의 사용이 증가하고 있는 추세이나, 아직까지 납축전지를 사용하는 자동차 시장이 주를 이루고 있다. In addition, the use of lithium ion batteries and AGM batteries using lithium as the next generation battery is increasing, but the automobile market using lead acid batteries is still dominant.

이러한 납축전지 배터리의 사용에 있어 수명 종지에 대한 판단 방법은 배터리의 전압을 측정하는 방법, 배터리 외관에 장착된 Indicator를 확인하는 방법 2가지가 있다. In the use of such a lead acid battery, there are two methods of determining the end of life: a method of measuring the voltage of the battery and a method of checking an indicator mounted on the exterior of the battery.

그러나, 배터리 수명에 대한 판단이 어려워 운전자들은 보통 배터리가 방전된 상태에서야 배터리 수명 종지에 대해 인지하여 교체를 하게 된다.However, it is difficult to determine the battery life, and drivers usually recognize the end of the battery life and replace it only when the battery is discharged.

한편, 최근 들어 자동차에 블랙박스, 하이패스, LED 주차번호판과 같은 편의 장비를 장착하는 것이 필수가 되었다. On the other hand, in recent years, it has become necessary to install convenient equipment such as a black box, a high pass, and an LED parking license plate.

이러한 장비들로 인해 납축전지는 기존의 시동용으로만 사용된다는 인식에서 벗어나 자동차 편의 장비들의 전원 공급의 역할까지 하게 되었으며, 납축전지의 용량과 내구성은 더욱 중요해졌다. Due to these equipments, lead acid batteries have gone beyond the perception that they are used only for starting, and have even served as power supply for automobile convenience equipment, and the capacity and durability of lead acid batteries have become more important.

하지만, 편의 장비의 상시전원 기능으로 장기간 주차 시, 납축전지의 방전이 발생하게 된다.However, when parking for a long period of time due to the constant power function of convenience equipment, the lead acid battery is discharged.

따라서, 이러한 방전을 예방하기 위한 기술을 본 발명을 통해 제안하게 된 것이다.Therefore, a technique for preventing such discharge has been proposed through the present invention.
