본 발명에 따른 보조 에너지 저장 장치를 이용한 방전 차량 점프 스타트 시스템은 방전 차량(40)의 배터리를 이용해 보조 에너지 저장장치(20)를 충전하는 충전 모듈(10)과, 충전 모듈(10)의 제어에 의해 충전되어 방전된 차량의 시동시에 필요한 전력을 공급하는 보조 에너지 저장 장치(20)와, 운전자가 시동을 거는 것을 감지하여 보조 에너지 저장 장치(20)의 전력을 방전 차량(40)의 시동 모터로 공급하는 시동 모듈(30)을 포함한다. The discharge vehicle jump start system using the auxiliary energy storage device according to the present invention includes a charging module 10 for charging the auxiliary energy storage device 20 using a battery of the discharge vehicle 40, and a control of the charging module 10. The auxiliary energy storage device 20 for supplying electric power necessary for the start of the vehicle charged and discharged by the vehicle, and the starter motor of the discharge vehicle 40 by detecting the driver's starting. It includes a start-up module 30 to supply.
이와 같은 구성을 갖는 본 발명에 따른 보조 에너지 저장 장치를 이용한 방전 차량 점프 스타트 시스템은 충전 모듈(10)이 방전된 차량 배터리를 이용해 보조 에너지 저장장치(20)를 충전하는 역할을 한다.The discharge vehicle jump start system using the auxiliary energy storage device according to the present invention having such a configuration serves to charge the auxiliary energy storage device 20 using the vehicle battery in which the charging module 10 is discharged.
보조 에너지 저장장치(20)는 용량에 비해 순간적인 전력이 강한 장치를 이용한다. 본 발명의 실시 예에서는 슈퍼캐패시터와 LTO 배터리(리튬티타늄화합물 배터리)를 사용할 수 있고 이로 제한되지 않는다.The auxiliary energy storage device 20 uses a device having a strong instantaneous power compared to the capacity. In an embodiment of the present invention, a supercapacitor and an LTO battery (lithium titanium compound battery) may be used, but are not limited thereto.
시동 모듈(30)은 보조 에너지 저장장치(20)의 충전이 완료된 후 운전자가 시동을 거는 것을 감지하여 보조 에너지 저장장치(20)를 차량에 연결시키고, 보조 에너지 저장장치(20)는 차량이 시동을 걸기에 충분한 전력을 공급하게 된다.The startup module 30 detects that the driver starts after the charging of the auxiliary energy storage device 20 is completed and connects the auxiliary energy storage device 20 to the vehicle, and the auxiliary energy storage device 20 starts the vehicle. It will supply enough power to make the call.
충전 모듈(10)은 Buck-Boost로 구현할 수 있으며, Power단과 제어단으로 구성되어 있다.The charging module 10 may be implemented as a Buck-Boost, and is composed of a power stage and a control stage.
그리고 충전 모듈(10)은 컨버터 컨트롤 로직부를 구비하고, 컨버터 컨트롤 로직부는 인덕터 L의 전류(IL)와 캐패시터 C의 전압(VCap), 배터리 전압(Vbatt)을 입력받고 2개의 스위치 소자의 입력신호(Gbuckboost)를 출력한다.In addition, the charging module 10 includes a converter control logic unit. The converter control logic unit receives the current I L of the inductor L, the voltage V Cap of the capacitor C, and the battery voltage V batt . Output the input signal (G buckboost ).
인덕터 L의 전류(IL)이 기준 값보다 커지면 스위치를 즉각 OFF 하고, 다음 주기에 ON 하는 피크 전류 모드 제어(Peak current mode control)를 하게 된다.When the current (I L ) of the inductor L is greater than the reference value, the switch is turned off immediately, and the peak current mode control is turned on in the next cycle.
여기서, 인덕터 L의 전류(IL)를 제어하는 이유는 작은 사이즈의 컨버터로 빠르게 슈퍼캐패시터를 충전하기 위한 것이다.The reason for control of the inductor L current (I L) is intended to rapidly charge the super capacitor in the converter of small size.
인덕터의 자기포화 전류점(Isaturation) 직전에서 (IL)을 제어하게 되면, 같은 L에서 최대한 빠르게 충전할 수 있다.Controlling (I L ) just before the inductor's self-saturation current point (I saturation ) allows charging as fast as possible at the same L.
또한, 평균 전류 모드 제어(Average current mode control)가 아닌 피크 전류 모드 제어(Peak current mode control)를 하는 것에 의해 (IL)을 안전하게 인덕터의 자기포화 전류점(Isaturation) 직전까지 제어할 수 있다.In addition, by performing peak current mode control instead of average current mode control, (I L ) can be safely controlled until just before the inductor's self saturation current point (I saturation ). .
또한, 충전이 완료되어 전압(VCap)이 기준에 도달하면 입력신호(Gbuckboost)를 OFF한다.In addition, when charging is completed and the voltage V Cap reaches the reference, the input signal G buckboost is turned off.
충전 모듈(10)은 평균 전류 모드 제어(Average current mode control)시에 Buck 구간 + Buck-Boost 구간 + Boost 구간으로 나누어 제어를 한다.The charging module 10 divides and controls the Buck section + Buck-Boost section + Boost section in the average current mode control.
그리고 보조 에너지 저장장치(20)로 사용되는 슈퍼캐패시터는 배터리 nominal voltage의 약 1.2배까지 충전한다.The supercapacitor used as the auxiliary energy storage device 20 charges up to about 1.2 times the nominal voltage of the battery.
소형차의 경우 12V배터리를 사용하므로 약 14.5V까지 충전하고, 대형버스나 화물트럭의 경우 24V배터리를 사용하므로 28~29V까지 충전한다.In the case of small cars, it charges up to about 14.5V because it uses 12V battery, and in the case of large bus or cargo truck, it charges up to 28 ~ 29V because it uses 24V battery.
그리고 충전 모듈(10)의 제어에 의해 슈퍼캐패시터가 완충되면, 시동 모듈(30)이 역할을 시작한다.When the supercapacitor is fully charged by the control of the charging module 10, the starter module 30 starts to play a role.
시동 모듈(10)은 스위치단과 제어단으로 구성되어 있다.The starting module 10 is composed of a switch stage and a control stage.
시동 모듈(10)은 시동 제어 로직부를 포함하고, 방전된 차량 배터리의 전압을 받아 스위치의 입력신호(Gstart)를 출력한다.The start module 10 includes a start control logic unit, and receives the voltage of the discharged vehicle battery and outputs an input signal G start of the switch.
운전자가 시동버튼을 눌러 시동을 걸게 되면, 차량 배터리의 전압이 급감하는데, 시동 제어 로직부에서 이를 감지하여 스위치를 닫아주어 슈퍼캐패시터의 전류가 시동모터로 갈 수 있게 한다.When the driver presses the start button to start the vehicle, the voltage of the vehicle battery drops sharply. The start control logic detects this and closes the switch so that the current of the supercapacitor goes to the starter motor.
배터리 전압(Vbatt)만을 센싱하기 때문에 자동차 배터리에 +극, -극을 연결하는 것에 의해 시동모터로 전력을 공급하는 시점을 감지할 수 있다.Since only the battery voltage (V batt ) is sensed, it is possible to detect the timing of supplying power to the starting motor by connecting the positive and negative poles to the car battery.
