친환경 자동차용 배터리 시스템은 자동차를 구동하기 위한 에너지를 저장, 공급하는 역할을 하고 있다.Eco-friendly automotive battery systems store and supply energy for driving cars.
그리고 종래에는 수많은 셀을 컨트롤 하기 위해 BMS와 같은 전장품이 사용되며, 이를 통해 셀 전압센싱 및 밸런싱 등을 진행하였었다.In the related art, electronic devices such as BMS are used to control a large number of cells, through which cell voltage sensing and balancing are performed.
그래서 차량 운행 및 충전 행위시 셀 간 전압 편차가 수mV내로 관리가 되도록 하고 있었다.Therefore, the voltage deviation between cells during the operation and charging of the vehicle was managed to be within a few mV.
종래의 배터리시스템이 HEV에서 EV로 가면서 고에너지/고용량화 됨에 따라 충/방전시 셀간 전압편차 관리가 더욱 중요시 되고 있다.이는 신뢰성 및 안전성에 모두 관련된 부분으로 전압편차가 관리되지 않을 시 차량단위에서 이상현상으로 인식하고 알람을 띄우게 된다. As the conventional battery system becomes higher energy / higher capacity from HEV to EV, management of voltage deviation between cells during charging / discharging becomes more important.This is related to both reliability and safety, and is abnormal in the vehicle unit when voltage deviation is not managed. The alarm is recognized as a phenomenon.
종래기술은 HEV, PHEV와 같이 배터리시스템이 엔진시스템과 같이 사용이 되면서 전압센싱 구조에 의한 전압편차 발생은 무시할 수 있는 수준으로 보고 있었다. In the prior art, as battery systems such as HEV and PHEV are used together with engine systems, voltage deviations caused by voltage sensing structures are considered to be negligible.
그러나 EV와 같이 배터리시스템으로만 구동이 되는 구조가 개발됨에 따라 배터리 이상 현상 발생 시 차량 알람 또는 차량 정지라는 최악의 경우가 발생될 수 있어, 배터리 시스템의 신뢰성 및 안전성이 더욱 중요해 지고 있다.However, as a structure that is driven only by a battery system such as EV is developed, the worst case such as a vehicle alarm or a vehicle stop may occur when a battery abnormality occurs, and the reliability and safety of the battery system become more important.
이를 해결하기 위해 하위단위인 배터리팩에서부터 전압편차가 발생될 수 있는 조건들을 개선할 필요가 있다.In order to solve this problem, it is necessary to improve the conditions under which the voltage deviation may occur from the lower battery pack.

본 발명을 충분히 이해하기 위해서 본 발명의 바람직한 실시예를 첨부 도면을 참조하여 설명한다. 본 발명의 실시예는 여러 가지 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상세히 설명하는 실시예로 한정되는 것으로 해석되어서는 안 된다. 본 실시예는 당업계에서 평균적인 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위하여 제공되는 것이다. 따라서 도면에서의 요소의 형상 등은 보다 명확한 설명을 강조하기 위해서 과장되어 표현될 수 있다. 각 도면에서 동일한 부재는 동일한 참조부호로 도시한 경우가 있음을 유의하여야 한다. 또한, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기능 및 구성에 대한 상세한 기술은 생략된다.In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiment of the present invention may be modified in various forms, the scope of the invention should not be construed as limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings and the like may be exaggerated to emphasize a more clear description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. In addition, detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.
본 발명에 따른 BMS는 배터리가 최적상태를 유지하고 안정적으로 사용되도록 배터리 상태를 모니터링 하며, 차량 제어기와 CAN 통신을 통한 협조 제어를 실시하는 장치이다. BMS according to the present invention is a device for monitoring the battery state to maintain the optimal state and use the battery stably, and to perform cooperative control through the vehicle controller and CAN communication.
예를 들어 리튬이온 전지의 경우 종래의 니켈 수소 전지 대비 사용범위가 넓어 이에 대한 지속적인 관리가 필요하여 배터리셀과 가장 가까운 부위의 전압을 측정하여 해당 정보를 BMS로 송출한다.For example, Li-ion batteries have a wider range of use than conventional nickel-metal hydride batteries, and require continuous management. Therefore, the lithium ion battery measures the voltage of the closest part to the battery cell and sends the information to the BMS.
종래기술 대비 본 발명의 구성의 차이점을 개략적으로 살펴보면, 최근 전기차의 주행거리 경쟁이 심화되면서 고용량의 배터리를 더 많이 장착하여 차량 요구조건을 만족 시키고자 하지만, 기존 HEV 및 EV와 달리 고용량의 배터리에서는 급 가감속등 사용자의 악의 사용 조건에 대하여 높은 전류 출력 특성을 나타내며, 이 때 마다 각 부위에서 발생하는 발열 현상은 연결 회로상의 저항 인자로 작용하게 된다. Looking at the difference of the configuration of the present invention compared to the prior art, in order to meet the vehicle requirements by mounting more batteries of high capacity as the mileage competition of electric vehicles intensifies in recent years, unlike conventional HEV and EV in high capacity batteries It shows high current output characteristics against the user's bad use condition such as sudden acceleration and deceleration, and the heat generation phenomenon in each part acts as a resistance factor on the connection circuit.
즉 종래의 기술은 배터리 셀의 가장 인접한 부분의 전압 측정을 목적에 두었다면, 본 발명은 배터리 모듈에서 발생 할 수 있는 저항 인자를 균등하게 분배하여 저항을 관리하는데 그 목적이 있다.That is, if the prior art is to measure the voltage of the nearest part of the battery cell, the present invention is to manage the resistance by equally distributing the resistance factor that can occur in the battery module.
도 2와 도 3에 도시된 바와 같이 본 발명은 다수의 셀 모듈과, 상기 셀 모듈을 구성하는 다수의 단위 셀 각각에 배터리 모듈 내 전압 센싱 버스바(1)를 통해 전압을 측정하고, 배터리 모듈의 직, 병렬 회로에서 발열에 의한 저항 인자를 도출하고, 상기 전압 센싱 바를 통한 전압 편차와 상기 저항을 일원화하여 저장하고 관리한다.(저항을 측정하는 것과 전압 편차 측정이 따로 설명되어 있어, 설명에서는 이 둘을 동시에 하는 것으로 하였습니다.)As shown in FIG. 2 and FIG. 3, the present invention measures a voltage through a plurality of cell modules and a voltage sensing busbar 1 in a battery module in each of a plurality of unit cells constituting the cell module. Deriving the resistance factor caused by heat generation in the parallel and parallel circuits, and unifying and storing and managing the voltage deviation through the voltage sensing bar and the resistance (Measurement of resistance and measurement of voltage deviation are described separately. I will do both at the same time.)
상기 전압 편차와 저항을 일원화하여 저장하고 관리하는 것은 전장품 미장착 상태에서 관리한다.The unified storage and management of the voltage deviation and resistance are managed in the absence of the electronics.
왜냐하면, 모든 조립품은 부품 품질로부터 품질 확보가 되기에 배터리 팩(전장품 미장착 상태)에서부터 전압편차를 개선할 수 있는 구조를 적용하여 신뢰성 및 안전성 확보하기 위함이다.Because all the assembly is to ensure the quality from the quality of the parts to apply the structure to improve the voltage deviation from the battery pack (without the electronics) to secure the reliability and safety.
상기 배터리 모듈이 최적상태를 유지하도록 상태를 모니터링 하는 BMS와 차량 제어기가 CAN 통신을 통해 상기 전압 편차와 저항값이 전송된다.The voltage deviation and the resistance value are transmitted through the CAN communication between the BMS and the vehicle controller which monitor the state so that the battery module remains in an optimal state.
즉, BMS는 배터리가 최적상태를 유지하고 안정적으로 사용되도록 배터리 상태를 모니터링 하며, 차량 제어기와 CAN 통신을 통한 제어를 실시한다.In other words, the BMS monitors the battery status so that the battery is in optimal condition and is used stably, and performs control through CAN communication with the vehicle controller.
상기 배터리 모듈에서 일정 거리 이내의 지점의 전압을 측정하여 해당 정보를 BMS로 송출하여 관리하도록 한다.The battery module measures the voltage of a point within a certain distance and sends the information to the BMS to manage.
이하 본 발명의 실시를 위한 방법에 대하여 자세히 설명한다.Hereinafter, a method for practicing the present invention will be described in detail.
본 발명은 발열 예상 부위의 거리를 균등 분배하고, 분배된 발열 예상 부위의 저항 인자를 측정하고 관리하며, 배터리 모듈에서 발생 할 수 있는 저항 인자를 균등하게 분배하여 저항을 관리한다.The present invention evenly distributes the distance of the expected heat generation site, measures and manages the resistance factor of the distributed heat generation expected site, and evenly distributes the resistance factors that may occur in the battery module to manage the resistance.
이 때 저항 인자와 더불어 전압 편차를 측정할 수 있으며 다양한 저항 측정 장치와 전압 편차 측정 장치가 사용될 수 있다.In this case, the voltage deviation can be measured together with the resistance factor, and various resistance measuring devices and voltage deviation measuring devices can be used.
그리고 전압 센싱 버스바를 통해 전압 편차를 측정한다.The voltage sensing busbar measures the voltage deviation.
차량 제어기와 CAN 통신을 통해 상기 전압 편차와 저항값이 전송되는데, 이러한 통신 방법에만 국한되는 것은 아니다.The voltage deviation and the resistance value are transmitted through CAN communication with the vehicle controller, but are not limited to this communication method.
본 발명은 상기 배터리 모듈에서 전압 편차와 저항값의 측정 부위를 10 ~ 20 mm로 유지한다.The present invention maintains the measured portion of the voltage deviation and the resistance value in the battery module to 10 ~ 20 mm.
예를 들어 도 5에 도시된 바와 같이, 개선후 측정 부위를 10 ~ 20 mm로 유지하는 경우 발열에 의한 저항 인자 도출과 거리 균등 분배를 통한 저항 인자 관리가 용이함을 알 수 있다.For example, as shown in Figure 5, it can be seen that when maintaining the measurement site after the improvement to 10 to 20 mm, it is easy to manage the resistance factor through derivation of resistance factor due to heat generation and equal distribution of distance.
