Description

배터리 보호 장치{BATTERY PROTECTION DEVICE}{BATTERY PROTECTION DEVICE}

본 발명은 배터리 보호 장치에 관한 것으로서, 차량용 배터리의 스웰링, 위치이탈 및 차량 충격에 의한 에어백 전개를 감지하여 각 감지 조건에 따라 배터리의 출력을 제어하여 배터리 및 차량의 안정성을 확보할 수 있는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a battery protection device, which detects a swelling of a battery for a vehicle, an airbag deployment due to a positional deviation and a vehicle impact, .

일반적으로 전기자동차 및 하이브리드 자동차에서 가장 비중을 많이 차지하는 주요 구성요소인 배터리는 충방전을 하면서 에너지를 저장하고 또한 방출한다.In general, batteries, which are the most important components in electric vehicles and hybrid vehicles, store and discharge energy while charging and discharging.

통상, 배터리의 과방전은 에너지가 소모되는 특성으로 인해 배터리 수명내구를 감소시키는데 그치지만, 과충전은 에너지가 축적되는 특성으로 인해 안전상 위험을 야기할 수 있다.Generally, overdischarge of a battery reduces the life of the battery due to energy consumption characteristics, but overcharging can cause safety risk due to the accumulation of energy.

배터리가 과충전되면, 배터리내부의 전해액이 분해 발열함으로써 내압 증가를 가져오고, 이러한 내압 증가로 내부 셀이 터질 경우 배터리는 발화 및 폭발할 수 있음에 기인된다.When the battery is overcharged, the electrolytic solution in the battery dissipates and generates heat, thereby increasing the internal pressure, and the battery may ignite and detonate when the internal cell ruptures due to the increase in the internal pressure.

이러한 배터리 과충전에 의한 팽창을 스웰링(Swelling)이라고 하며, 스웰링에 의한 배터리 발화 및 폭발을 방지하기 위해 배터리 장치에는 과 충전에 대한 안전회로가 반드시 구비됨으로써 충전 시 배터리가 발화 및 폭발의 상태까지 가기 전에 더 이상의 충전을 막아 주고, 이로부터 고객의 안전을 위한 배터리 안전성(FAIL SAFETY)을 확보해야 한다.Such swelling due to battery overcharging is called swelling. In order to prevent battery ignition and explosion by swelling, a safety circuit for overcharging is necessarily installed in the battery device, so that the battery is in a state of ignition and explosion Before you go, you must prevent further charging and ensure that you have FAIL SAFETY for your safety.

또한 차량의 급출발 급제동시 배터리가 고정되어 있는 트레이에서 이탈될 경우 주행에 의한 들뜸으로 인해 배터리와 배터리 전원을 공급하는 와이어에 파손이 발생할 수 있으며, 배터리에서 전압이 계속적으로 출력되는 경우, 고전압 스파크가 발생할 수 있어 이러한 상황에 대한 안정성 역시 확보되어야 한다.In addition, if the battery is suddenly discharged from the tray when the battery is suddenly discharged, there is a risk of damage to the wire supplying the battery and the battery due to lifting due to driving. If the battery continuously outputs a voltage, And the stability of such a situation should be ensured.

또한 차량에 에어백이 전개될 정도의 충돌이 발생한 경우에도 배터리 계통에 손상이 발생할 수 있어 출력되는 전원이 차단되어 배터리 및 차량의 안정성을 확보해야한다.In addition, even if a collision occurs such that the airbag is deployed in the vehicle, the battery system may be damaged, so that the output power is cut off to secure the stability of the battery and the vehicle.

이에 본 발명은 차량용 배터리의 스웰링, 위치이탈 및 차량 충격에 의한 에어백 전개를 감지하여 각 감지 조건에 따라 배터리의 출력을 제어하여 배터리 및 차량의 안정성을 확보할 수 있는 배터리 보호 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention provides a battery protection device capable of detecting the swelling, the positional deviation, and the deployment of the airbag due to a vehicle impact, and controlling the output of the battery according to each sensing condition to secure the stability of the battery and the vehicle.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

도 1은 본 발명의 일 실시 예에 따른 배터리 보호 장치의 개략적인 구성도이다.1 is a schematic block diagram of a battery protection device according to an embodiment of the present invention.

도 1을 참조하면 본 발명의 일 실시 예에 따른 배터리 보호 장치(100)는 배터리(10)의 스웰링을 감지하는 제1스위치(110), 배터리(10)의 이탈을 감지하는 제2스위치(20), 에어백(20)의 전개를 감지하는 에어벡 전개 감지부(150), 배터리(10)의 스웰링 및 이탈 또는 에어백(20) 전개 중 어느 하나가 감지됐는지 판단하는 판단부(130) 및 판단부(130)의 결과에 따라 배터리(10)의 출력을 제어하는 제어부(140)를 포함하여 구성된다.Referring to FIG. 1, a battery protection apparatus 100 according to an embodiment of the present invention includes a first switch 110 for detecting swelling of a battery 10, a second switch An airbag deployment detecting unit 150 for sensing the deployment of the airbag 20, a determination unit 130 for determining whether swelling or departure of the battery 10 or deployment of the airbag 20 is detected, And a controller 140 for controlling the output of the battery 10 according to a result of the determination unit 130. [

먼저 제1스위치(110)는 배터리(10)의 일측면에 대향되도록 배치되어 배터리(10)가 과충전되어 배터리(10) 팩이 부풀어 오르는 스웰링 현상이 발생하면, 부풀어오른 배터리(10) 팩에 의해 눌려지도록 구비된다.The first switch 110 is arranged to be opposed to one side of the battery 10 so that when the battery 10 is overcharged and a swelling phenomenon occurs in which the battery pack 10 swells up, As shown in Fig.

따라서 제1스위치(110)는 푸쉬스위치로 구성되며, 배터리(10)가 스웰링에 의해 부풀어 오르는 방향, 즉 배터리(10) 내의 셀이 직렬로 적층되어 있는 방향에 푸쉬스위치가 대향되도록 배치되어야 한다.Therefore, the first switch 110 is constituted by a push switch and should be disposed such that the push switch is opposed to the direction in which the battery 10 is swollen by the swelling, that is, the direction in which the cells in the battery 10 are stacked in series .

또한 제1스위치(110)는 배터리(10)가 정상적으로 동작할 때는 눌려지지 않고 배터리(10)가 과충전에 의해 부풀어 오르는 경우에만 눌려지도록 실험 및 계산에 의해 기설정된 간격을 두고 배치되어야 한다.Also, the first switch 110 should be disposed at predetermined intervals by experiments and calculations so that the first switch 110 is pushed only when the battery 10 is not pressed when the battery 10 normally operates, and when the battery 10 is inflated by overcharging.

제1스위치(110)는 부풀어오른 배터리(10)에 의해 눌려지면 기설정된 신호를 발생시켜 판단부(130)로 전송한다.When the first switch 110 is pressed by the inflated battery 10, the first switch 110 generates a predetermined signal and transmits it to the determination unit 130.

다음으로 제2스위치(120)는 제1스위치(110)와 마찬가지로 배터리(10)의 일측면에 대향되도록 배치되어 배터리(10)가 위치를 이탈하면 눌려지도록 구비된다.Next, the second switch 120 is arranged to be opposed to one side of the battery 10, like the first switch 110, so that it is pressed when the battery 10 is released.

따라서 제2스위치(120) 역시 푸쉬스위치로 구성되며, 배터리(10)가 장착되어 있는 트레이에서 이탈되면 눌려질 수 있는 방향으로 실험 및 계산에 의해 기설정된 간격을 두고 배치되어야 한다.Therefore, the second switch 120 is also configured as a push switch, and must be disposed at predetermined intervals by experiments and calculations in a direction in which the second switch 120 can be depressed when the battery 10 is detached from the tray on which the battery 10 is mounted.

제1스위치(110)와 마찬가지로 제2스위치(120)도 배터리(10)의 위치이탈에 의해 눌려지면 기설정된 신호를 발생시켜 판단부(130)로 전송한다.Similarly to the first switch 110, when the second switch 120 is depressed due to the displacement of the battery 10, a predetermined signal is generated and transmitted to the determination unit 130.

에어백 전개 감지부(150)는 차량에 충격이 발생하거나 충돌 사고가 발생하여 에어백(20)이 전개되면 이를 감지하여 판단부(130)에 신호를 전송하는 구성이다. The airbag deployment detecting unit 150 senses the airbag 20 deployed when a shock or collision occurs in the vehicle and transmits a signal to the determining unit 130. [

에어백 전개 감지부(150)는 에어백(20)이 전개되면 발생되는 특정 주파수 신호를 감지하거나, 또는 전개에 의해 부풀어오른 에어백(20)의 압력을 감지하는 등의 다양한 방법으로 에어백(20)의 전개를 감지할 수 있으며, 감지 방법 및 적용 구성에 대해서는 본원발명에 기재된 실시예에 한정하지 않는다.The airbag deployment detecting unit 150 detects a specific frequency signal generated when the airbag 20 is deployed or detects the pressure of the inflated airbag 20 by developing the airbag 20, And the detection method and application configuration are not limited to the embodiments described in the present invention.

이상에서 설명한 것과 같이 제1스위치(110)는 배터리(10)에 스웰링이 발생하면 눌려지게 되는데 이러한 조건을 제1조건, 제2스위치(120)가 배터리(10)의 위치이탈에 의해 눌려지는 조건을 제2조건, 에어백 전개 감지부(150)가 에어백(20)의 전개를 감지하는 조건을 제3조건으로 하고, 판단부(130)는 제1스위치(110), 제2스위치(120), 에어백 전개 감지부(150)로부터 입력되는 신호를 이용하여 제1조건, 제2조건, 제3조건 중 어느 하나의 조건이라도 만족하는지를 판단하여 그 결과를 제어부(140)에 전송하게 된다.As described above, the first switch 110 is pressed when swelling occurs in the battery 10. This condition is a first condition when the second switch 120 is pressed by the displacement of the battery 10 The condition is the second condition and the condition that the airbag deployment sensing unit 150 senses the deployment of the airbag 20 is the third condition, and the determination unit 130 determines that the first switch 110, the second switch 120, The controller 150 determines whether any one of the first condition, the second condition, and the third condition is satisfied by using the signal input from the airbag deployment detecting unit 150, and transmits the result to the controller 140.

즉, 배터리(10)에 스웰링이 발생하거나, 배터리(10)가 위치를 이탈하거나, 에어백(20)이 전개되면 그 결과를 제어부(140)에 전송하여 배터리(10)의 출력을 제어하도록 하는 것이다.That is, when swelling occurs in the battery 10, the battery 10 is displaced, or the airbag 20 is deployed, the result is transmitted to the control unit 140 to control the output of the battery 10 will be.

제어부(140)는 제1 내지 제3조건 중 어느 하나의 조건이라도 만족하면, 배터리(10)의 출력을 OFF시켜 배터리(10)에 발생한 과충전 또는 위치이탈 또는 차량에 발생한 충돌 및 충격에 의한 배터리(10) 폭발과 같은 사고를 미연에 방지 할 수 있도록 한다.If any one of the first to third conditions is satisfied, the control unit 140 turns off the output of the battery 10 to stop the battery 10 from being overcharged or displaced, 10) To prevent accidents such as explosions.

그러나, 만약 차량에 충격이 발생하여 에어백(20)이 전개된 제3조건을 만족한 경우, 에어백(20)이 전개될 정도의 충격은 발생하였으나, 배터리(10)는 정상 충전상태이고, 위치도 이탈되지 않아 문제가 없는 경우에는 배터리(10)를 계속 OFF시켜야 할 필요성이 없을 수 있으며, 충돌이나 충격에 의해 도로 한가운데 멈춰있는 차량을 도로 가장자리로 이동시켜야 할 필요성이 있을 수 있다.However, if an impact occurs in the vehicle and the airbag 20 meets the expanded third condition, an impact is generated such that the airbag 20 is deployed, but the battery 10 is in a normal charging state, If there is no problem, there is no need to keep the battery 10 OFF, and there may be a need to move the vehicle stopped in the middle of the road to the edge of the road due to collision or impact.

이런 경우, 배터리(10)의 출력이 계속 OFF되어 있다면, 차량에 시동이 걸리지 않아 차량을 이동시킬 수 없어 2차 사고가 발생될 수도 있다.In this case, if the output of the battery 10 is continuously OFF, the vehicle can not be moved because the vehicle is not started, and a secondary accident may occur.

따라서 제어부(140)는 제3조건, 즉, 에어백 전개 감지부(150)가 에어백(20) 전개를 감지하여 배터리(10) 출력을 OFF 시킨 경우, 배터리(10)의 스웰링을 감지하고, 위치이탈을 감지하는 제1조건과 제2조건을 모두 만족하지 않는다면, 기설정된 시간이 지난 후 다시 배터리(10) 출력을 ON시켜 차량에 시동을 걸고 안전한 곳으로 이동시킬 수 있도록 한다.The controller 140 senses the swelling of the battery 10 when the airbag deployment detecting unit 150 senses the deployment of the airbag 20 and turns off the output of the battery 10, If the first condition and the second condition for detecting the departure are not satisfied, the output of the battery 10 is turned on again after a predetermined time, so that the vehicle can be started and moved to a safe place.

즉, 배터리 보호 장치(100)는 차량에 충돌이나 충격이 발생하여 에어백(20)이 전개된 경우, 일시적으로 배터리(10)의 출력을 차단시켜 충돌/충격 직후의 사고 발생 위험으로부터 차량을 보호하지만, 배터리(10)에는 과충전과 위치이탈이 없고, 에어백(20)만 전개된 상황이라면 다시 차단된 배터리(10)의 출력을 ON시켜 차량의 운행은 가능하도록 하여 2차 사고를 예방할 수 있도록 한다.That is, when the airbag 20 is deployed due to a collision or an impact on the vehicle, the battery protecting apparatus 100 temporarily blocks the output of the battery 10 to protect the vehicle from the risk of an accident immediately after the collision / impact , The battery 10 is not overcharged or displaced, and if only the airbag 20 is deployed, the output of the battery 10 is turned on again to enable the vehicle to be operated, thereby preventing a secondary accident.

도 2는 본 발명의 일 실시예에 따른 배터리 보호 장치를 이용한 배터리 보호 방법의 흐름도이다.2 is a flowchart of a battery protection method using a battery protection device according to an embodiment of the present invention.

먼저 판단부가 제1스위치(110)가 배터리(10)의 스웰링에 의해 눌려지거나, 제2스위치(120)가 배터리(10)의 위치이탈에 의해 눌려지거나, 에어백 전개 감지부(150)가 에어백(20) 전개를 감지하는지 각각 판단하는 단계(S101, S103, S105)를 수행한다.The first switch 110 is first pressed by the swelling of the battery 10 or the second switch 120 is pressed by the disengagement of the battery 10 or the airbag deployment detecting unit 150 detects that the airbag (S101, S103, and S105), respectively, whether or not the detection of the development of the mobile terminal 20 is performed.

다음으로 S101, S103, S105 단계 중 어느 하나의 조건이라도 만족하면 제어부(140)가 배터리(10)의 출력을 OFF시키는 단계(S107)를 수행한다.Next, if any of the conditions of S101, S103, and S105 is satisfied, the control unit 140 performs a step S107 of turning off the output of the battery 10.

다음으로 에어백(20)만 전개되고, 제1스위치(110) 및 제2스위치(120)는 눌려지지 않은 경우(S109), 제어부가(140) 기설정된 시간 이후 다시 배터리(10) 출력을 ON시켜(S111) 차량에 시동이 걸려 이동될 수 있도록 한다.When the first switch 110 and the second switch 120 are not pressed (S109), the controller 140 turns on the output of the battery 10 again after a predetermined time (140) (S111) so that the vehicle can be started and moved.

이러한 과정을 통해 배터리 보호 장치(100)는 배터리(10)를 과충전에 의한 폭발로부터 보호하고, 위치이탈에 의한 사고로부터 배터리(10)와 차량을 보호하며, 충돌이나 충격에 의해 에어백(20)이 전개된 순간 배터리(10) 전압에 의한 추가적인 사고를 방지한다. 또한 배터리(10)가 정상인 상태에서 에어백(20)만 전개된 경우, 일시적으로 배터리(10)의 출력을 차단했다가 다시 ON시켜 차량을 충돌 발생지점으로부터 이동할 수 있도록 제어하여 도로상의 2차 사고로부터 차량을 보호한다.The battery protection device 100 protects the battery 10 from explosion due to overcharging, protects the battery 10 and the vehicle from an accident caused by displacement, Thereby preventing additional accidents caused by the voltage of the battery 10 when the battery 10 is deployed. When only the airbag 20 is deployed in a normal state of the battery 10, the output of the battery 10 is temporarily cut off and then turned on again to control the vehicle to move from the point of occurrence of the collision, Protect the vehicle.
