Description

공용 주차장에 설치되는 전기차 무선 충전 시스템{WIRELESS CHARGING SYSTEM FOR ELECTRIC VEHICLE USING SMART-PHONE}Electric vehicle wireless charging system installed in public parking lots {WIRELESS CHARGING SYSTEM FOR ELECTRIC VEHICLE USING SMART-PHONE}

본 발명은 전기차 무선 충전 시스템 기술로서, 보다 상세하게는 아파트 지하 주차장, 건물 유료 주차장, 또는 회사 지하 주차장과 같은 공용 주차장에 설치되는 전기차 무선 충전 시스템에 관한 것이다.The present invention relates to an electric vehicle wireless charging system technology, and more particularly, to an electric vehicle wireless charging system installed in a public parking lot such as an apartment underground parking lot, a building paid parking lot, or a company underground parking lot.

전기차는 전기를 전력공급원으로 하여 운행하는 자동차를 의미한다. 즉, 자동차 자체에 전력공급원 충전이 가능한 배터리를 탑재하고, 탑재된 배터리에서 공급되는 전력을 이용하여 운행하는 것을 전기차라 한다. 이러한 전기차는 배터리의 충전시간이 오래 걸리며, 또한 한번 충전에 의해 주행하는 거리가 제한적이다. 따라서 전기차는 목적한 이동거리를 확보하기 위해서는 자주 충전을 해주어야 한다.An electric vehicle refers to a vehicle that operates using electricity as a power supply source. In other words, an electric vehicle is an electric vehicle in which a battery capable of being charged from a power supply source is mounted on the vehicle itself and operated using power supplied from the mounted battery. These electric vehicles take a long time to charge the battery, and the distance traveled by one charge is limited. Therefore, electric vehicles need to be recharged frequently to secure the desired travel distance.

전기차는 그 하부에 설치된 충전코일의 위치와 지상으로부터의 높이가 차종별로 다르다. 이에 전기차의 하부에 설치된 충전코일과 충전소의 무선충전패드의 정확한 위치맞춤으로 양측 코일 간의 에어 갭을 줄여 고효율의 충전이 가능하도록 하는 동시에, 양측 코일을 최대한 근접시켜 전자파의 누설이 최소화되도록 함으로써 인체나 기기에 가해지는 영향을 최소화할 필요가 있다.For electric vehicles, the position of the charging coil installed at the bottom and the height from the ground are different for each vehicle type. Accordingly, the precise positioning of the charging coil installed at the bottom of the electric vehicle and the wireless charging pad of the charging station reduces the air gap between the coils on both sides to enable high-efficiency charging, and at the same time, the leakage of electromagnetic waves is minimized by bringing the coils on both sides as close as possible, thereby harming the human body and It is necessary to minimize the impact on the equipment.

전기차의 차종별로 그 하부에 설치된 충전코일의 위치와 지상으로부터의 높이가 다르더라도, 전기차의 하부에 설치된 충전코일과 충전소의 무선충전패드의 정확한 위치맞춤을 통해 전기차를 무선충전할 때 충전 오류 또는 충전 불량을 최소화하는 기술이 요구되고 있다.Even if the position of the charging coil installed on the lower part of the electric vehicle and the height from the ground are different for each type of vehicle, charging errors or charging errors occur during wireless charging of the electric vehicle through accurate positioning of the charging coil installed on the lower part of the electric vehicle and the wireless charging pad of the charging station. A technique for minimizing defects is required.

한편, 향후 전기차가 내연기관 자동차를 대체할 만큼 많이 보급되고, 그에 따라 전기 충전소가 아파트 지하 주차장, 건물 유료 주차장, 또는 회사 지하 주차장과 같은 공용 주차장에 설치되어 운영되는 경우 보다 쉽고 간편하게 셀프 방식으로 운영할 수 있도록 하는 기술이 요구되고 있다.On the other hand, in the future, if electric vehicles become widespread enough to replace internal combustion engine vehicles, and accordingly, electric charging stations are installed and operated in public parking lots such as apartment underground parking lots, building paid parking lots, or company underground parking lots, self-operating is easier and simpler. Skills are required to make this possible.

무선 충전 방식에는 크게 3가지 방식으로 나뉜다. 전자기 유도, 자기 공진, 마이크로파 방식이 있다. 전자기 유도 방식은 주로 루프형 코일을 수백 kHz이하의 주파수에서 사용하며 전송효율을 높이기 위해 전송거리를 작게 하며 송수신 코일을 일치시켜야 한다. 자기 공진 방식은 전자기 유도 방식과 마찬가지로 루프형 코일을 사용하지만, 공진 코일의 공진 현상을 이용한 것으로, 10MHz 대역을 사용하며, 상호인덕턴스가 작아져도 공진현상을 이용하므로 전송효율이 높다. 마이크로파 방식은 수백 MHz 이상의 마이크로파를 안테나에서 방사하여 전력을 수신하는 방식이다.There are three main types of wireless charging methods. There are electromagnetic induction, magnetic resonance, and microwave methods. The electromagnetic induction method mainly uses a loop-type coil at a frequency of several hundred kHz or less, and in order to increase transmission efficiency, the transmission distance must be reduced and the transmission and reception coils must be matched. The self-resonance method uses a loop-type coil like the electromagnetic induction method, but uses the resonance phenomenon of the resonant coil, uses a 10 MHz band, and uses the resonance phenomenon even when the mutual inductance is reduced, so the transmission efficiency is high.
