It relates to a device and a method for controlling an insulation resistance control device.

일반적으로, 친환경 자동차(HEV, EV, HFCV, 기타)는 고전압을 이용하여 차량을 구동하게 된다. 이러한 친환경 자동차는 주요 구성품의 하나인 전원 분배 유닛(Power Distribution Unit; PDU)을 이용하여, 차량의 에너지원인 고전압 배터리로부터 전원을 공급받아 각 고전압 유닛에 전압을 분배하는 주요 기능을 수행한다.In general, eco-friendly vehicles (HEV, EV, HFCV, etc.) drive the vehicle using a high voltage. Such an eco-friendly vehicle uses a power distribution unit (PDU), which is one of the main components, to receive power from a high-voltage battery, which is the vehicle's energy source, and perform a main function of distributing voltage to each high-voltage unit.

친환경 자동차에서 사용하는 전원은 일반적으로 시스템에 따라 고전압과 저전압으로 구분된다. 예컨대, 차량 구동, 공조 및 충전 관련 시스템은 고전압을 사용하며, 각종 램프, 모터, 센서, 미디어, 에어백 등 일반 엔진 구동 차량의 전기 장치들은 저전압(12V)을 사용한다.Power used in eco-friendly vehicles is generally divided into high voltage and low voltage depending on the system. For example, a system related to vehicle driving, air conditioning, and charging uses a high voltage, and electric devices of a general engine driven vehicle such as various lamps, motors, sensors, media, and airbags use a low voltage (12V).

그 중 고전압 시스템은 직ㅇ간접 접촉에 의한 인체 감전사고를 방지하기 위하여 시스템 절연은 100Ω/Vdc, 500Ω/Vdc 이상으로 유지하도록 규정하고 있다.Among them, high voltage systems are stipulated to maintain system insulation at 100Ω/Vdc, 500Ω/Vdc or more to prevent electric shock accidents caused by direct or indirect contact.

친환경 자동차에서 누설 전류 및 절연저항 검출에 대한 종래의 기술이 하기의 <특허문헌 1> 대한민국 공개특허 공개번호 10-2014-0076975호(2014.06.23. 공개)와 <특허문헌 2> 대한민국 등록특허 등록번호 10-1101270호(2011.12.26. 등록) 및 <특허문헌 3> 대한민국 공개특허 공개번호 10-2009-0012456호(2009.02.04. 공개)에 개시되었다.The conventional technology for detecting leakage current and insulation resistance in an eco-friendly vehicle has been registered with the following <Patent Document 1> Korean Patent Publication No. 10-2014-0076975 (published on Jun. 23, 2014) and <Patent Document 2> Korea Registered Patent No. 10-1101270 (registered on Dec. 26, 2011) and <Patent Document 3> were disclosed in Korean Patent Laid-Open No. 10-2009-0012456 (published on Feb. 4, 2009).

<특허문헌 1>에 개시된 종래기술은 배터리로부터 출력되는 직류 전압을 전력 반도체를 이용하여 다상 교류 전압으로 변환하는 인버터, 인버터에서 출력되는 신호를 이용하여 누설 전류 발생 여부를 판단하며, 판단 결과 누설 전류 발생 시 모터로의 전류 흐름을 차단하는 전류 감시부를 포함하고, 인버터 또는 모터 시스템의 고전압 배터리의 절연 불량으로 발생 가능한 위험을 사전에 경고하여 운전자의 안전성을 보장하도록 한다.In the prior art disclosed in <Patent Document 1>, an inverter that converts a DC voltage output from a battery into a polyphase AC voltage using a power semiconductor, and a signal output from the inverter determine whether leakage current occurs, and as a result of the determination, leakage current It includes a current monitoring unit that blocks the flow of current to the motor when it occurs, and warns of possible dangers due to poor insulation of the inverter or high-voltage battery of the motor system to ensure driver safety.

<특허문헌 2>에 개시된 종래기술은 친환경 자동차의 절연저항을 측정함에 있어, 정확한 절연저항의 측정에 요구되는 충분한 인가전압과 측정 해상도를 제공한다.The prior art disclosed in <Patent Document 2> provides sufficient applied voltage and measurement resolution required for accurate insulation resistance measurement in measuring the insulation resistance of an eco-friendly vehicle.

<특허문헌 3>에 개시된 종래기술은 고전압을 사용하는 차량에서 고전압부와 샤시 간에 절연내력의 상태를 검출하여 일정 수위 이상으로 절연내력이 감소할 경우 이를 탑승자에게 경고하도록 한 고전압 사용 차량의 절연내력 측정 시스템을 제공한다.The prior art disclosed in <Patent Document 3> detects the state of the dielectric strength between the high voltage part and the chassis in the vehicle using the high voltage and warns the occupant when the dielectric strength decreases above a certain level. A measurement system is provided.

그러나 상기와 같은 종래기술들은 고전압 배터리로부터 제공되는 고전압을 고전압 유닛 및 저전압 유닛에 분배해주는 전원 분배 유닛(PDU)의 절연상태를 검출하는 것은 불가능하다는 단점이 있다.However, the conventional techniques as described above have a disadvantage in that it is impossible to detect the insulation state of the power distribution unit (PDU) that distributes the high voltage provided from the high voltage battery to the high voltage unit and the low voltage unit.

또한, 차량이 정지 상태일 경우 절연상태 검출 결과를 분석하여 절연파괴로 판단되는 경우에 시동을 제한하는 기능이 없어, 절연파괴로 운전자가 감전될 우려가 있으며, 차량 부품이 손상될 우려가 있었다.In addition, when the vehicle is in a stationary state, there is no function to limit the start when it is determined that insulation breakdown by analyzing the insulation state detection result, there is a risk of electric shock to the driver due to insulation breakdown, and there is a risk of damage to vehicle parts.

따라서, 고전압계와 저전압계의 절연 상태를 정확하게 감지하여, 사용자가 위험으로부터 안전이 보장될 수 있는 제어방법 및 제어회로에 관한 기술적 수단이 필요한 실정이다.Accordingly, there is a need for a control method and a technical means for a control circuit that can accurately detect the insulation state of the high voltmeter and the low voltmeter, and ensure that the user is safe from danger.

이때, 절연저항 제어장치의 BMS(Battery Management System, 101)는 특정 위치에 배치되는 제1스위치(SW1) 및 제2스위치(SW2)를 포함하는 구성이다. 구체적으로, 제1스위치(SW1)은 전기차 배터리 또는 연료전지차 스택의 일단부와 연결되고, 제2스위치(SW2)는 전기차 배터리 또는 연료전지차 스택의 타단부와 연결된다.At this time, the BMS (Battery Management System, 101) of the insulation resistance control device is a configuration including a first switch (SW1) and a second switch (SW2) disposed at a specific position. Specifically, the first switch SW1 is connected to one end of the electric vehicle battery or fuel cell vehicle stack, and the second switch SW2 is connected to the other end of the electric vehicle battery or fuel cell vehicle stack.

도 2에는 본 발명의 일 실시예에 따른 절연저항 제어장치 제어방법을 나타내는 순서도가 도시되어 있다.2 is a flowchart illustrating a method for controlling an insulation resistance control device according to an embodiment of the present invention.

이하에서는, 도 1과 도 2를 참조하여, 본 발명의 일 실시예에 따른 절연저항 제어장치의 구동 원리와 제어장치 제어방법에 대해 상세히 설명한다.Hereinafter, with reference to FIGS. 1 and 2 , a driving principle of an insulation resistance control device and a control device control method according to an embodiment of the present invention will be described in detail.

본 실시예에 따른 절연저항 제어방법(S100)은, 절연저항 측정단계(S110), 정상제어 단계(S120) 및 비정상 제어단계(S130)로 구분될 수 있다.The insulation resistance control method ( S100 ) according to the present embodiment may be divided into an insulation resistance measurement step ( S110 ), a normal control step ( S120 ), and an abnormal control step ( S130 ).

절연저항 측정단계(S110)에서는, 도 2에 도시된 바와 같이, 차량이 IG On되면 BMS(Battery Management System, 101)가 Wake up되어 절연저항(120)의 양단의 저항값을 측정한다. 구체적으로, 제1스위치(SW1)만을 닫힘(close)상태로 제어한 후 절연저항(120)의 일단의 저항값을 측정한다. 또한, 제2스위치(SW2)만을 닫힘(close)상태로 제어한 후 절연저항(120)의 타단의 저항값을 측정한다.In the insulation resistance measurement step S110 , as shown in FIG. 2 , when the vehicle is IG On, a Battery Management System (BMS) 101 wakes up to measure the resistance values of both ends of the insulation resistance 120 . Specifically, after controlling only the first switch SW1 to a closed state, the resistance value of one end of the insulation resistor 120 is measured. In addition, after controlling only the second switch SW2 to the closed state, the resistance value of the other end of the insulation resistor 120 is measured.

정상제어 단계(S120)에서는, 절연저항 측정단계(S110)로부터 검출된 저항값이 정상 범위 내에 있을 경우, 세이프티 플러그(130)를 닫힘(close) 상태로 제어하고, 이후 차량의 정상 주행이 진행되며, 운전자에 의해 차량이 IG Off되는 경우에는 세이프티 플러그(130)를 열림(open) 상태로 제어한 후, 차량의 시동을 Off하는 차량시동정지 제어단계(S140)가 수행된다.In the normal control step (S120), when the resistance value detected from the insulation resistance measurement step (S110) is within the normal range, the safety plug 130 is controlled to the closed state, and then the vehicle is driven normally. , when the vehicle is IG Off by the driver, after controlling the safety plug 130 to an open state, the vehicle start/stop control step S140 of turning off the vehicle is performed.

한편, 비정상 제어단계(S130)에서는, 절연저항 측정단계(S110)로부터 검출된 저항값이 정상 범위를 벗어날 경우, 세이프티 플러그(130)를 열림(open) 상태로 제어하게 된다.On the other hand, in the abnormal control step ( S130 ), when the resistance value detected in the insulation resistance measurement step ( S110 ) is out of the normal range, the safety plug 130 is controlled to an open state.

구체적으로, 검출된 저항값이 정상 범위를 벗어날 경우, 세이프티 플러그(130)를 열림(open) 상태로 제어함과 동시에, BMS와 연결된 상위 시스템에 차량 절연 저항(120)에 문제가 발생했음을 통보하고 차량 주행을 차단할 수 있다.Specifically, when the detected resistance value is out of the normal range, the safety plug 130 is controlled in an open state and, at the same time, notifies the upper system connected to the BMS that a problem has occurred in the vehicle insulation resistance 120, and Vehicle driving can be blocked.

종래 기술에 따르면, 정비 작업자의 실수로 세이프티 플러그(Safety plug)가 꽂혀 있는 상태에서 정비를 수행할 수 있다. 이 경우, 고전압 배터리 및 인접한 주변 장치를 정비하게 되어 감전 사고가 발생될 수 있다. 반면, 본 발명에 따른 BMS가 On되어 절연저항을 측정한 후, 절연저항이 정상일 경우에만 세이프티 플러그(Safety plug)를 담힘(close) 동작을 수행하도록 함으로써, 상기 언급한 안전사고 발생을 미연에 차단할 수 있다.According to the prior art, maintenance can be performed in a state in which a safety plug is accidentally inserted by a maintenance worker. In this case, the high-voltage battery and adjacent peripheral devices may be maintained and an electric shock accident may occur. On the other hand, after the BMS according to the present invention is turned on and the insulation resistance is measured, the safety plug close operation is performed only when the insulation resistance is normal, thereby preventing the above-mentioned safety accident from occurring in advance. can

또한, 본 발명에 따르면, 세이프티 플러그(Safety plug)가 열림(open) 상태에서 절연 저항을 측정할 수 있어, 절연저항 측정 계산식이 현저히 간소화될 수 있다.In addition, according to the present invention, since the insulation resistance can be measured in an open state of the safety plug, the insulation resistance measurement calculation formula can be significantly simplified.

구체적으로, 세이프티 플러그(Safety Plug Relay)가 열림(open)상태에서 제1스위치(SW1)를 닫고, R_PU(도 1 참조)와 절연저항의 일단(R_leak(+)) 간의 전압 분배를 이용하여, 절연저항의 일단(R_leak(+))에 인가되는 전압을 BMS 내에 탑재된 마이컴 ADC를 통해 센싱할 수 있다. 이때, 측정된 전압값을 기준으로 절연저항의 일단(R_leak(+))의 전압값을 산출할 수 있다.Specifically, when the safety plug relay is open, the first switch SW1 is closed, and the voltage distribution between R_PU (see FIG. 1) and one end of the insulation resistance (R_leak(+)) is used, The voltage applied to one end (R_leak(+)) of the insulation resistor can be sensed through the microcomputer ADC mounted in the BMS. At this time, the voltage value of one end (R_leak(+)) of the insulation resistance may be calculated based on the measured voltage value.

계산 식 예)Calculation formula example)

R_leak(+)/{R_leak(+) + R_PU} * 5V = V_R_leak(+)R_leak(+)/{R_leak(+) + R_PU} * 5V = V_R_leak(+)

이때, R_PU는 고정값이며, V_R_leak(+)는 마이컴을 통해 센싱한 후 계산을 통해 R_leak(+)을 산출할 수 있다.In this case, R_PU is a fixed value, and V_R_leak(+) may be sensed through a microcomputer and then R_leak(+) may be calculated through calculation.

또한, 절연저항의 타단의 전압값을 산출하는 방법에 대해 설명하면, 세이프티 플러그(Safety Plug Relay)가 열림(open) 상태에서 제2스위치(SW2)를 닫고, R_PU(도 1참조)와 절연저항의 타단(R_leak(-)) 간의 전압 분배를 이용하여, 절연저항의 타단(R_leak(-))에 인가되는 전압을 BMS 내에 탑재된 마이컴 ADC를 통해 센싱할 수 있다. 이때, 측정된 전압값을 기준으로 절연저항의 일단(R_leak(-))의 전압값을 산출할 수 있다.In addition, if the method of calculating the voltage value of the other end of the insulation resistance is described, the second switch SW2 is closed when the safety plug relay is open, and R_PU (refer to FIG. 1) and the insulation resistance The voltage applied to the other end (R_leak(-)) of the insulation resistance can be sensed through the microcomputer ADC mounted in the BMS by using the voltage division between the other end (R_leak(-)) of the BMS. At this time, the voltage value of one end (R_leak(-)) of the insulation resistance may be calculated based on the measured voltage value.

계산 식 예)Calculation formula example)

R_leak(-)/{R_leak(-) + R_PU} * 5V = V_R_leak(-)R_leak(-)/{R_leak(-) + R_PU} * 5V = V_R_leak(-)

이때, R_PU는 고정값이며, V_R_leak(-)는 마이컴을 통해 센싱한 후 계산을 통해 R_leak(-)을 산출할 수 있다.In this case, R_PU is a fixed value, and V_R_leak(-) may be sensed through a microcomputer and then R_leak(-) may be calculated through calculation.

앞서 언급한 바와 같이, 종래기술들은 고전압 배터리로부터 제공되는 고전압을 고전압 유닛 및 저전압 유닛에 분배해주는 전원 분배 유닛(PDU)의 절연상태를 검출하는 것이 불가능하다는 단점이 있다. 또한, 차량이 정지 상태일 경우 절연상태 검출 결과를 분석하여 절연파괴로 판단되는 경우에 시동을 제한하는 기능이 없어, 절연파괴로 운전자가 감전될 우려가 있으며, 차량 부품이 손상될 우려가 있었다.As mentioned above, the prior art has a disadvantage in that it is impossible to detect the insulation state of the power distribution unit (PDU) that distributes the high voltage provided from the high voltage battery to the high voltage unit and the low voltage unit. In addition, when the vehicle is in a stationary state, there is no function to limit the start when it is determined that insulation breakdown by analyzing the insulation state detection result, there is a risk of electric shock to the driver due to insulation breakdown, and there is a risk of damage to vehicle parts.

본 발명의 실시 예에 따르면, 특정 역할을 수행하는 접속라인, 절연저항, 세이프티 플러그 및 세이프티 플러그 제어부를 구비함으로써, 차량 고전압 관련 장치 정비 중 발생할 수 있는 안전사고를 미연에 방지할 수 있고, 절연 저항 산출을 위한 계산식을 간소화 할 수 있으며, 차량 시동 정지 시 불필요한 누설 전류를 차단할 수 있는 구성을 포함하는 고전압계와 저전압계의 절연 상태를 감지하여, 사용자가 위험으로부터 안전할 수 있는 구성을 포함하는 절연저항 제어장치 및 절연저항 제어장치 제어방법을 제공할 수 있다.According to an embodiment of the present invention, by providing a connection line, an insulation resistance, a safety plug, and a safety plug control unit that perform a specific role, it is possible to prevent a safety accident that may occur during maintenance of a vehicle high voltage-related device in advance, and the insulation resistance The calculation formula for calculation can be simplified, and the insulation including the configuration that allows the user to be safe from danger by detecting the insulation state of the high voltmeter and low voltmeter including a configuration that can block unnecessary leakage current when the vehicle starts and stops A resistance control device and an insulation resistance control device control method can be provided.
