Description

유무선충전모듈 중 더욱 신속한 충전이 가능한 충전모듈을 선택하여 충전하는 전기자동차 {ELECTRIC VEHICLE FOR SELECTING FASTER CHARGING MODULE BETWEEN WIRE AND WIRELESS CHARGING MODULE}An electric vehicle that is charged by selecting a charging module that allows faster charging among wired and wireless charging modules {ELECTRIC VEHICLE FOR SELECTING FASTER CHARGING MODULE BETWEEN WIRE AND WIRELESS CHARGING MODULE}

본 발명은 전기자동차의 충전기술에 관한 것이다.The present invention relates to charging technology for electric vehicles.

전기자동차는 배터리에 저장된 전기에너지를 이용하여 주행하는 자동차이다. 전기자동차의 배터리를 충전하는 기술로는 유선충전과 무선충전이 있다.An electric vehicle is a vehicle that runs using electrical energy stored in a battery. Technologies for charging electric vehicle batteries include wired charging and wireless charging.

유선충전기술은 충전장치의 충전케이블을 직접 전기자동차에 연결한 후 배터리를 충전하는 방법이고, 무선충전기술은 직접적인 케이블 연결없이 전기에너지를 전달하는 방법이다. 예를 들어 대한민국 특허등록공보 제10-1132770호는 유선충전기술과 그에 대한 과금에 대해 개시한다.Wired charging technology is a method of charging the battery after connecting the charging cable of the charging device directly to the electric vehicle, while wireless charging technology is a method of transmitting electrical energy without a direct cable connection. For example, Republic of Korea Patent Registration No. 10-1132770 discloses wired charging technology and its charging.

그런데 종래기술에 따르면 운전자는 어떤 충전방식을 사용해야 가장 빠른 시간 내에 충전되는지 알 수 없어 불편했다. 유선충전이든 무선충전이든 배터리를 충전하는 데는 상당한 시간이 소요되는데, 유선과 무선 방식 중 어느 방식으로 충전해야 더 빨리 충전되는지 알 수 없었기 때문에 임의로 충전방식을 선택해야했다.However, according to the prior art, it was inconvenient for the driver to not know which charging method to use to charge the vehicle in the fastest time. It takes a considerable amount of time to charge the battery, whether wired or wireless, and since I couldn't tell which method would charge faster, wired or wireless, I had to choose the charging method arbitrarily.

본 발명의 발명가는 이러한 문제점들을 해결할 수 있는 기술을 완성하기 위하여 오랫동안 연구 노력한 끝에 본 발명을 완성하기에 이르렀다.The inventor of the present invention has completed the present invention after a long period of research and effort in order to complete a technology that can solve these problems.

본 발명의 목적은 유선 및 무선충전모듈을 모두 탑재한 전기자동차를 제공하는 것에 있다.The purpose of the present invention is to provide an electric vehicle equipped with both wired and wireless charging modules.

또한, 본 발명의 목적은 유선충전모듈 또는 무선충전모듈 중 더 빠른 충전이 가능한 충전모듈을 자동으로 선택하여 충전하는 전기자동차를 제공하는 것에 있다.Additionally, the purpose of the present invention is to provide an electric vehicle that automatically selects and charges a charging module capable of faster charging among a wired charging module or a wireless charging module.

한편, 본 발명의 명시되지 않은 또 다른 목적들은 하기의 상세한 설명 및 그 효과로부터 용이하게 추론할 수 있는 범위 내에서 추가적으로 고려될 것이다.Meanwhile, other unspecified purposes of the present invention will be additionally considered within the scope that can be easily inferred from the following detailed description and its effects.

It is better to control the switching unit so that a module that provides a larger charging amount charges the battery.

바람직한 실시예에서 상기 유선충전모듈은 외부 유선충전장치로부터 연장된 충전케이블이 체결되는 유선충전단자; 및In a preferred embodiment, the wired charging module includes a wired charging terminal to which a charging cable extending from an external wired charging device is connected; and

또한, 본 발명의 전기자동차가 자동으로 유선충전과 무선충전 중에서 더욱 빠른 충전방법을 선택하여 신속하게 배터리를 충전할 수 있다. 그러므로 운전자는 어느 충전모듈을 사용해야 가장 신속하게 충전할 수 있는지 고민하지 않아도 된다.Additionally, the electric vehicle of the present invention can automatically select a faster charging method between wired charging and wireless charging to quickly charge the battery. Therefore, drivers do not have to worry about which charging module to use for the fastest charging.

Also, in describing the present invention, if it is determined that related known functions may unnecessarily obscure the gist of the present invention as they are obvious to those skilled in the art, the detailed description thereof will be omitted.

본 발명의 전기자동차는 유선충전모듈과 무선충전모듈이 모두 탑재되어 있다. 그러므로 본 발명의 전기자동차는 유선충전만 제공하는 충전장소와 무선충전만 제공하는 충전장소 어디에서는 자유롭게 배터리를 충전할 수 있다.The electric vehicle of the present invention is equipped with both a wired charging module and a wireless charging module. Therefore, the electric vehicle of the present invention can freely charge its battery at either a charging location that provides only wired charging or a charging location that provides only wireless charging.

뿐만 아니라 본 발명의 전기자동차는 유선충전과 무선충전이 동시에 가능한 충전장소에서 어느 충전모듈을 사용하는 것이 가장 신속하게 충전할 수 있는지 판단할 수 있다. 또한, 스위칭부를 통해 더 빨리 충전할 수 있는 충전모듈을 활성화하여 충전할 수 있다. 이하에서는 본 발명의 구체적인 구성의 바람직한 실시예에 대하여 상세하게 설명한다.In addition, the electric vehicle of the present invention can determine which charging module can be used to charge the fastest at a charging location where wired charging and wireless charging are possible simultaneously. In addition, charging can be done by activating a charging module that can charge faster through the switching unit. Hereinafter, preferred embodiments of the specific configuration of the present invention will be described in detail.

도 1은 본 발명의 전기자동차 및 충전장치의 바람직한 실시예를 나타내는 도면이다.1 is a diagram showing a preferred embodiment of the electric vehicle and charging device of the present invention.

도 1에서 알 수 있듯이, 본 발명의 전기자동차(100)는 유선충전모듈(110), 무선충전모듈(120), 스위칭부(130), 배터리(140), 제어부(150)를 포함한다. 전기자동차(100)는 외부의 전기자동차 충전장치(200)로부터 유선 또는 무선으로 전기에너지를 공급받아 배터리(140)를 충전한다.As can be seen in Figure 1, the electric vehicle 100 of the present invention includes a wired charging module 110, a wireless charging module 120, a switching unit 130, a battery 140, and a control unit 150. The electric vehicle 100 receives electrical energy wired or wirelessly from an external electric vehicle charging device 200 and charges the battery 140.

유선충전모듈(110)은 외부 유선충전장치(210)로부터 유선으로 전력을 수신한다. 유선충전모듈(110)은 유선충전케이블(211)을 통해 직접 전기에너지를 공급받으며 그 형식에는 특별한 제한이 없다. 예를 들어, 교류 삼상 380V를 이용하는 급속충전방식이나 교류 단상 220V를 이용하는 완송충전방식을 포함하여 새롭게 정의되는 유선충전표준을 모두 포함할 수 있다. The wired charging module 110 receives power by wire from the external wired charging device 210. The wired charging module 110 receives electric energy directly through the wired charging cable 211, and there are no particular restrictions on its format. For example, it can include all newly defined wired charging standards, including the fast charging method using three-phase AC 380V or the slow charging method using AC single-phase 220V.

무선충전모듈(120)은 외부 무선충전장치(220)로부터 무선으로 전력을 수신한다. 무선충전모듈(120)이 무선으로 전력을 수신하기 위해 사용하는 방식에는 특별한 제한이 없다. 예를 들어, 근거리 무선전송방법으로 자기유도방식과 자기공명방식, 원거리 무선전송방법으로 마이크로파방식 및 레이져방식 등이 본 발명의 무선충전모듈(120)에 적용될 수 있다.The wireless charging module 120 wirelessly receives power from the external wireless charging device 220. There is no particular limitation on the method used by the wireless charging module 120 to receive power wirelessly. For example, magnetic induction and magnetic resonance methods as short-distance wireless transmission methods, and microwave and laser methods as long-distance wireless transmission methods can be applied to the wireless charging module 120 of the present invention.

스위칭부(130)의 전단은 유선충전모듈(110) 및 무선충전모듈(120)에 연결되고, 후단은 배터리(140)에 연결된다. 스위칭부(130)는 스위칭소자를 이용하여 유선충전모듈(110) 및 무선충전모듈(120)에서 전달되는 전력을 택일적으로 배터리(140)에 전달한다.The front end of the switching unit 130 is connected to the wired charging module 110 and the wireless charging module 120, and the rear end is connected to the battery 140. The switching unit 130 selectively transfers power delivered from the wired charging module 110 and the wireless charging module 120 to the battery 140 using a switching element.

배터리(140)는 전기에너지를 축적한다. 예를 들어 배터리(140)는 배터리팩, 배터리를 제어하는 BMS, 냉각부를 포함할 수 있다. 배터리팩은 복수의 배터리셀을 포함하는 배터리 모듈을 포함할 수 있다. 배터리셀은 양극소재, 음극소재, 전해역, 분리막을 이용하여 제작한다. 다만, 본 발명에 사용되는 배터리(140)의 종류와 용량에는 특별한 제한이 없다.The battery 140 accumulates electrical energy. For example, the battery 140 may include a battery pack, a BMS that controls the battery, and a cooling unit. The battery pack may include a battery module including a plurality of battery cells. Battery cells are manufactured using anode materials, cathode materials, electrolytes, and separators. However, there is no particular limitation on the type and capacity of the battery 140 used in the present invention.

제어부(150)는 유선충전모듈(110)에서 충전되는 전력량을 연산하고, 무선충전모듈(120)에서 충전되는 전력량을 연산한다. 제어부(150)는 연산된 전력량을 비교하여 어떤 충전모듈을 이용했을 때 더욱 신속하게 배터리(140)를 충전할 수 있는지 결정한다. 결정이 완료되면 제어부(150)는 스위칭부(130)를 제어하여 유선충전모듈(110) 또는 무선충전모듈(120) 중 어느 하나가 배터리(140)를 충전하도록 한다.The control unit 150 calculates the amount of power charged in the wired charging module 110 and calculates the amount of power charged in the wireless charging module 120.
