非接触で電力を伝送する方法として、電磁誘導（数１００ｋＨｚ）による電磁誘導型、電界または磁界共鳴を介したＬＣ共振間伝送による電界・磁界共鳴型、電波（数ＧＨｚ）によるマイクロ波送電型、あるいは可視光領域の電磁波（光）によるレーザ送電型が知られている。この中で既に実用化されているのは、電磁誘導型である。これは簡易な回路（トランス方式）で実現可能であるなどの優位性はあるが、送電距離が短いという課題もある。 As a method of transmitting power in a non-contact manner, electromagnetic induction type by electromagnetic induction (several 100 kHz), electric field / magnetic field resonance type by transmission between LC resonances via electric field or magnetic field resonance, microwave transmission type by radio wave (several GHz), Alternatively, a laser transmission type using electromagnetic waves (light) in the visible light region is known. Of these, the one that has already been put into practical use is the electromagnetic induction type. This has advantages such as being feasible with a simple circuit (transformer method), but it also has the problem of a short transmission distance.

そこで、共振を利用して電力を数ｍ先まで伝送する共鳴給電方式が提案され、この技術を利用した製品開発が、電機メーカー、自動車メーカーを中心に進められている。 Therefore, a resonance feeding method that uses resonance to transmit electric power up to several meters has been proposed, and product development using this technology is being promoted mainly by electric appliance makers and automobile makers.

従来は送電側から受電側への片方向の非接触電力伝送が主流ではあるが、双方向に非接触電力伝送を行う技術が特許文献１に開示されている。 Conventionally, one-way non-contact power transmission from the power transmission side to the power reception side has been the mainstream, but Patent Document 1 discloses a technique for bidirectional non-contact power transmission.

また、車両において、蓄電容量が少ない車両に路側電源または蓄電容量に余裕がある車両か非接触で給電する技術が特許文献２に開示されている。 Further, in the vehicle, Patent Document 2 discloses a technique of supplying power to a vehicle having a small storage capacity by a roadside power source, a vehicle having a sufficient storage capacity, or a non-contact power supply.

しかしながら、特許文献１記載の発明では、送電方向と送電量を自動で決めることができない。 However, in the invention described in Patent Document 1, the power transmission direction and the power transmission amount cannot be automatically determined.

また、特許文献２記載の発明では、蓄電容量に余裕が有るもの同士の送電方向と送電量を自動で決定する、定置充電器までの距離を考慮に入れた送電方向と送電量を自動で決定する、蓄電容量が少ない方から多い方への送電方向と送電量を自動で決定する、２台の移動体を送受電可能な位置に置き任意のタイミングで送受電する等の動作を行うことができない。 Further, in the invention described in Patent Document 2, the power transmission direction and the power transmission amount are automatically determined between those having a sufficient storage capacity, and the power transmission direction and the power transmission amount are automatically determined in consideration of the distance to the stationary charger. It is possible to automatically determine the transmission direction and transmission amount from the one with the smaller storage capacity to the one with the larger storage capacity, place the two moving objects in a position where they can transmit and receive power, and perform operations such as transmitting and receiving power at any time. Can not.

上記問題を解決するため、本発明の移動体は、非接触により電力の送電および電力の受電をすることが可能な非接触電力送受電手段と、前記電力を充電する蓄電手段と、前記蓄電手段の前記電力により移動する移動手段と、通信を行う通信手段と、を備えた移動体であって、前記蓄電手段に蓄えられている電力量、又は前記電力量から求められる移動可能距離、又は前記電力量から求められる充電比率、に基づいて前記移動手段における充電要求度を算出する制御手段を有し、複数の前記移動体の間で前記通信を行うことにより、各々の前記移動体における前記充電要求度を取得し、複数の前記移動体の間で、前記充電要求度が等しくなるように前記電力を送電および受電することを特徴とする。 In order to solve the above problems, the mobile body of the present invention includes a non-contact power transmission / reception means capable of transmitting and receiving power by non-contact, a power storage means for charging the power, and the power storage means. A mobile body including a moving means that moves by the electric power and a communication means that performs communication, and the amount of electric power stored in the electric energy storage means, or the movable distance obtained from the electric energy, or the said. It has a control means for calculating the charging requirement in the moving means based on the charging ratio obtained from the electric energy, and by performing the communication between the plurality of the moving bodies, the charging in each of the moving bodies is performed. It is characterized in that the required degree is acquired and the electric power is transmitted and received so that the required charge degree becomes equal among the plurality of mobile bodies.

本発明によれば、移動体間での充放電方向と充電量を決定することで、電力量に余裕がある移動体から電力量が不足している移動体へ電力を移動することができ、かつ送電側が電力を過剰に送りすぎて電力量が不足することを防ぐことができる。 According to the present invention, by determining the charge / discharge direction and the charge amount between the moving bodies, it is possible to transfer the electric power from the moving body having a sufficient electric power amount to the moving body having an insufficient electric power amount.

＜実施の形態１＞
図１に、本発明の実施の形態１における双方向非接触電力伝送装置を備える移動体の構成を示す。ここでは、移動体１と移動体２の２台による組み合わせを示している。 <Embodiment 1>
FIG. 1 shows a configuration of a mobile body including a bidirectional non-contact power transmission device according to the first embodiment of the present invention. Here, a combination of two mobile bodies 1 and 2 is shown.

移動体１および移動体２は同様の構成であり、それぞれ送電側または受電側のどちらかに切り替わって動作することができる。以下、移動体１と同様の部分に関する移動体２の説明は省略する。 The mobile body 1 and the mobile body 2 have the same configuration, and can operate by switching to either the power transmission side or the power reception side, respectively. Hereinafter, the description of the moving body 2 regarding the same portion as the moving body 1 will be omitted.

移動体１は高周波電力を非接触伝送で送電または受電するための送受電コイル５を有する。 The mobile body 1 has a power transmission / reception coil 5 for transmitting or receiving high-frequency power by non-contact transmission.

送受電回路３は、移動体１が送電を行うときには送受電コイル５に高周波電力を供給し、移動体１が送電を行うときには送受電コイル５が受電した高周波電力の整流などを行い直流電力に変換する。 The power transmission / reception circuit 3 supplies high-frequency power to the power transmission / reception coil 5 when the mobile body 1 transmits power, and rectifies the high-frequency power received by the power transmission / reception coil 5 when the mobile body 1 transmits power to direct current power. Convert.

蓄電部７は、リチウムイオン電池、ニッケル水素電池、鉛蓄電池などの二次電池で構成され、移動体１が送電を行うときには送受電回路３に対して電力を供給し、移動体１が受電を行うときには送受電回路３から供給される電力を蓄電する。 The power storage unit 7 is composed of a secondary battery such as a lithium ion battery, a nickel hydrogen battery, or a lead storage battery. When the mobile body 1 transmits power, power is supplied to the power transmission / reception circuit 3, and the mobile body 1 receives power. When doing so, the electric power supplied from the power transmission / reception circuit 3 is stored.

移動部９は、移動体１が移動を行うときに蓄電部７の電力で動作する動力源であり、陸上の移動体であればモーターとタイヤ、空中の移動体であればモーターとプロペラ、水上や水中の移動体であればモーターとスクリューなどで構成される。 The moving unit 9 is a power source that operates with the electric power of the power storage unit 7 when the moving body 1 moves, and is a motor and a tire for a moving body on land, a motor and a propeller for a moving body in the air, and water. If it is a moving body in water or underwater, it is composed of a motor and a screw.

制御部１１はマイコン等により構成され、蓄電部７の蓄電容量の情報などから移動体１がどれだけ充電されることを必要としているかの充電要求度を計算する。 The control unit 11 is configured by a microcomputer or the like, and calculates the charging requirement degree of how much the mobile body 1 needs to be charged from the information on the storage capacity of the storage unit 7.

充電要求度の形式は問わないが、ここでは充電要求度は蓄電容量が少ないときには充電要求度は高く最大で１００、蓄電容量が多いときには充電要求度は低く最小で０とする。必要に応じて他の定義とすることも可能である。 The format of the charge requirement is not limited, but here, when the storage capacity is small, the charge requirement is high and the maximum is 100, and when the storage capacity is large, the charge requirement is low and the minimum is 0. Other definitions are possible as needed.

蓄電容量と充電要求度は、蓄電容量が増加すると充電要求度が減少または変化しない広義単調減少な関係が望ましい。 It is desirable that the storage capacity and the charging requirement have a broadly monotonous relationship in which the charging requirement does not decrease or change as the storage capacity increases.

簡単な充電要求度の算出方法としては、蓄電池の充電割合が０％のときは充電要求度１００、蓄電池の充電割合が１００％のときには充電要求度０とすることができる。この時の充電池の充電割合と充電要求度の関係を図２に示す。 As a simple method for calculating the charge requirement, the charge requirement 100 can be set when the charge ratio of the storage battery is 0%, and the charge requirement 0 can be set when the charge ratio of the storage battery is 100%. FIG. 2 shows the relationship between the charging ratio of the rechargeable battery and the charging requirement at this time.

また、同じ蓄電容量であっても、移動体によって移動できる距離が異なる場合には、充電要求度は、蓄電池の残量から計算される残走行可能距離から求めることが好適である。残走行距離が一定距離よりも短いときには充電要求度が特に高く、残走行距離が一定距離よりも長いときには充電要求度が特に低いことが、さらに好適である。このような残走行可能距離と充電要求度の関係の一例を図３ａと図３ｂに示す。蓄電容量から計算される残走行可能距離が０～２０ｋｍと短いときには充電要求度が１００と高く、１２０ｋｍ以上と長いときには充電要求度が０と低く、２０ｋｍから１２０ｋｍの間は充電要求度が順次減少している。 Further, even if the storage capacity is the same, when the distance that can be moved differs depending on the moving body, it is preferable to obtain the charging requirement from the remaining travelable distance calculated from the remaining amount of the storage battery. It is more preferable that the charging requirement is particularly high when the remaining mileage is shorter than a certain distance, and the charging requirement is particularly low when the remaining mileage is longer than a certain distance. An example of the relationship between the remaining mileage and the charge requirement is shown in FIGS. 3a and 3b. When the remaining mileage calculated from the storage capacity is as short as 0 to 20 km, the charge requirement is as high as 100, when it is as long as 120 km or more, the charge requirement is as low as 0, and the charge requirement gradually decreases between 20 km and 120 km. is doing.

この蓄電容量あるいは残走行可能距離と要求度の関係は、一つの固定の関係を使うこともできるが、移動体の機体・用途・使う場所などによって自動又は手動で適切に設定されることが望ましい。また、複数の関係を必要に応じて使い分けることもできる。 The relationship between the storage capacity or the remaining mileage and the required degree can be one fixed relationship, but it is desirable to set it automatically or manually depending on the aircraft, application, place of use, etc. of the moving object. .. In addition, multiple relationships can be used properly as needed.

制御部１１は、移動体２に対して移動体１の充電要求度を送信し、移動体２から送信された移動体２の充電要求度を受信し、移動体２の充電要求度の比較を行い、移動体１が送電を行うか受電を行うかと送受電の電力量を計算する。 The control unit 11 transmits the charging requirement of the moving body 1 to the moving body 2, receives the charging request of the moving body 2 transmitted from the moving body 2, and compares the charging request of the moving body 2. Then, the amount of power for transmission and reception is calculated as to whether the mobile body 1 transmits or receives power.

移動体１の充電要求度が移動体２の充電要求度よりも大きいときには移動体２から移動体１へ送電を行い、移動体２の充電要求度が移動体１の充電要求度よりも大きいときには移動体１から移動体２へ送電を行うように送受電方向を決定する。そして、送電が行われた後に充電要求度が等しくなるように送電量を決定する。以上の送受電方向と送電量の決定に従い、送受電回路３を制御する。 When the charging requirement of the moving body 1 is larger than the charging requirement of the moving body 2, power is transmitted from the moving body 2 to the moving body 1, and when the charging requirement of the moving body 2 is larger than the charging requirement of the moving body 1. The power transmission / reception direction is determined so that power is transmitted from the mobile body 1 to the mobile body 2. Then, the amount of power transmission is determined so that the charging requirements become equal after the power transmission is performed. The power transmission / reception circuit 3 is controlled according to the above determination of the power transmission / reception direction and the power transmission amount.

通信部１３は無線による情報の送受信を行う装置で、ワイヤレス電力伝送と別個の周波数を使った免許不要で使える通信方式であるＩＥＥＥ８０２．１５．４（ＺｉｇＢｅｅ（登録商標））、ＩＥＥＥ８０２．１５．１(Ｂｌｕｅｔｏｏｔｈ（登録商標）)、ＩＥＥＥ８０２．１１(無線ＬＡＮ)等の利用が好適に使えるが光通信や音波通信などの他の通信方式でも良いし、ワイヤレス電力伝送の周波数を使った通信方式も使うことができる。制御部１１が算出した充電要求度を通信部１３から通信部１４を経由して移動体２に送信し、移動体２の制御部１２が算出した充電要求度を通信部１４から通信部１３を経由して受信し、要求度算出部１１に伝送する。
移動体２も移動体１と同様に、送受電回路４、送受電コイル６、蓄電部８、移動部１０、制御部１２、通信部１４から構成され、同様の動作をおこなう。ただし、移動体１と移動体２を組み合わせた動作で、移動体１が送電側のときには移動体２が受電側、移動体１が受電側のときは移動体２が送電側として動作するように制御を行う。 The communication unit 13 is a device that transmits and receives information wirelessly, and is a communication method that can be used without a license using a frequency separate from wireless power transmission. (Bluetooth (registered trademark)), IEEE802.11 (wireless LAN), etc. can be preferably used, but other communication methods such as optical communication and sonic communication may be used, and communication methods using the frequency of wireless power transmission are also used. be able to. The charging request degree calculated by the control unit 11 is transmitted from the communication unit 13 to the mobile body 2 via the communication unit 14, and the charging request degree calculated by the control unit 12 of the mobile body 2 is transmitted from the communication unit 14 to the communication unit 13. It is received via and transmitted to the request degree calculation unit 11.
Like the mobile body 1, the mobile body 2 is composed of a power transmission / reception circuit 4, a power transmission / reception coil 6, a power storage unit 8, a mobile unit 10, a control unit 12, and a communication unit 14, and performs the same operation. However, in the operation of combining the moving body 1 and the moving body 2, when the moving body 1 is the power transmitting side, the moving body 2 operates as the power receiving side, and when the moving body 1 is the power receiving side, the moving body 2 operates as the power transmitting side. Take control.

以上が、本発明の本発明の双方向非接触電力伝送装置を備える移動体の動作の概略である。 The above is an outline of the operation of the mobile body including the bidirectional non-contact power transmission device of the present invention of the present invention.

本発明は、双方向非接触電力伝送装置を備える移動体の移動体１の制御部１１および移動体２の制御部１２における要求度の算出による送受電方向の決定と送電量の制御に特徴がある。 The present invention is characterized in determining the power transmission / reception direction and controlling the power transmission amount by calculating the degree of demand in the control unit 11 of the mobile body 1 and the control unit 12 of the mobile body 2 provided with the bidirectional non-contact power transmission device. be.

以下では、制御部の動作を中心に説明する。残走行距離と充電要求度の関係が図３ａと図３ｂであり、移動体１の残電力量が２０ｋＷｈで移動体２の残電力量が１００ｋＷｈ、移動体１の走行距離１ｋｍに必要な電力量が２ｋＷｈで移動体２の層京距離１ｋｍに必要な電力量が１ｋＷｈである図４の条件であるときを例にして説明を行う。 Hereinafter, the operation of the control unit will be mainly described. The relationship between the remaining mileage and the charging requirement is shown in FIGS. 3a and 3b. The remaining power amount of the moving body 1 is 20kWh, the remaining power amount of the moving body 2 is 100kWh, and the power amount required for the mileage of the moving body 1 is 1km. The description will be given by taking as an example the condition of FIG. 4 in which the amount of electric power required for the layer distance of 1 km of the moving body 2 is 1 kWh at 2 kWh.

図５は本発明の実施の形態における制御のフローチャートである。２台の移動体が非接触電力伝送可能な範囲に移動した時に動作を開始することができる。移動体が人によって移動制御されているときには人が移動させ、自動で移動制御されているときには自動で移動する。開始は、人がボタンなどを押すことで開始することもできるし、移動体双方が非接触電力伝送可能な範囲に入ったことを検出して自動で開始することもできる。 FIG. 5 is a flow chart of control according to the embodiment of the present invention. The operation can be started when the two mobile bodies move within the range where non-contact power can be transmitted. When the moving body is controlled by a person, the person moves it, and when the moving object is automatically controlled, the moving body moves automatically. The start can be started by a person pressing a button or the like, or can be started automatically by detecting that both mobile bodies have entered the range where non-contact power can be transmitted.

動作を開始した場合、制御部１１は、蓄電部７の蓄電池の残量から充電要求度を算出する。図４に記載の条件では、移動体１の残電力量は２０ｋＷｈで、走行距離１ｋｍに必要な電力量は２ｋＷｈであるため、残走行距離は１０ｋｍであり、移動体１の充電要求度は図６のように１００となる。移動体２では同様に、残電力量は１００ｋＷｈで、走行距離１ｋｍに必要な電力量は１ｋＷｈであるため、残走行距離は１００ｋｍであり、移動体２の充電要求度は２０となる。（ステップＳ１０１）
制御部１１は、通信部１３を使って移動体１側の充電要求度Ａとして１００を通信で送信する。また、移動体２側の充電要求度Ｂである２０を通信で受信する。（ステップＳ１０２）
移動体１の要求度が移動体２側へ、移動体２の要求度が移動体１へ通信が完了しているか確認をする。通信が完了していないときはステップＳ１０２に戻り、通信が完了しているときには次のステップへ進む。一定時間以内に通信が終了しないときには終了処理などが必要となるが、ここでは省略する。（ステップＳ１０３）
制御部１１は、移動体１の充電要求度Ａである１００と移動体２の充電要求度Ｂである１０から、移動体間の送電方向と送電電力量を算出する。充電要求度Ａ＞充電要求度Ｂであるため、移動体１は受電側となる。移動体２の制御部１２も同様の処理を行い、移動体２が送電側となる。移動体１と移動体２の充電要求度が一致する電力量を計算すると、図７ａのように６０ｋＷｈが算出され、その電力量を送電した後の移動体１と移動体２の残電力量と残走行距離と要求度は図７ｂのようになる。ここでは制御部１１と制御部１２が同様の処理を行ったが、どちらか片方が処理を行なって送電か受電かの決定と送受電する電力量を計算し、他方へ通信で伝達しても良い。ここでは説明を単純化するため、送電した電力がそのまま受電されるものとして説明したが、送電側の蓄電池から減少する蓄電量と受電側に増加する蓄電量の比率である送受電効率を考慮に入れることが望ましい。（ステップＳ１０４）
制御部１１は、ステップＳ１０４の結果により移動体１が受電側となることが決まったので、受電動作ステップＳ１０９進む。（ステップＳ１０５）
制御部１１は、送受電コイル５が受電コイルとして移動体２からのワイヤレス電力を受電し、送受電回路３が受電回路として受電した電力を整流と電圧の変換を行い、蓄電部７に電力が蓄電されるように制御する。（ステップＳ１０９）
制御部１１は、必要な電力を受電し終わった、または送電側からの送電が終了するなどにより受電が終了するかを判定し、受電が終了しないときには受電動作を続け、受電が終了したときには受電終了動作に進む。（ステップＳ１１０）
制御部１１は、送受電回路を停止する。（ステップＳ１１１）
以上の動作により、移動体１の受電動作が完了する。 When the operation is started, the control unit 11 calculates the charge request degree from the remaining amount of the storage battery of the power storage unit 7. Under the conditions shown in FIG. 4, the remaining electric power of the moving body 1 is 20kWh, and the amount of electric power required for the traveling distance of 1km is 2kWh. Therefore, the remaining traveling distance is 10km, and the charging requirement of the moving body 1 is shown in FIG. It becomes 100 like 6. Similarly, in the mobile body 2, the remaining electric power amount is 100 kWh, and the electric energy required for the mileage of 1 km is 1 kWh. Therefore, the remaining mileage is 100 km, and the charging requirement of the mobile body 2 is 20. (Step S101)
The control unit 11 uses the communication unit 13 to transmit 100 as the charge request degree A on the mobile body 1 side by communication. Further, the charging request degree B 20 on the mobile body 2 side is received by communication. (Step S102)
It is confirmed whether the communication of the required degree of the moving body 1 to the moving body 2 side and the required degree of the moving body 2 to the moving body 1 are completed. If the communication is not completed, the process returns to step S102, and if the communication is completed, the process proceeds to the next step. If communication is not completed within a certain period of time, termination processing is required, but this is omitted here. (Step S103)
The control unit 11 calculates the power transmission direction and the amount of power transmitted between the mobile bodies from 100, which is the charge requirement degree A of the mobile body 1, and 10 which is the charge request degree B of the mobile body 2. Since the charging requirement A> the charging requirement B, the mobile body 1 is on the power receiving side. The control unit 12 of the mobile body 2 also performs the same processing, and the mobile body 2 becomes the power transmission side. When the amount of power that matches the charging requirements of the moving body 1 and the moving body 2 is calculated, 60kWh is calculated as shown in FIG. 7a, and the remaining power amount of the moving body 1 and the moving body 2 after transmitting the power amount. The remaining mileage and the required degree are as shown in FIG. 7b. Here, the control unit 11 and the control unit 12 perform the same processing, but even if one of them performs the processing to determine whether to transmit or receive power, calculate the amount of power to be transmitted or received, and transmit the power to the other by communication. good. Here, for the sake of simplification of the explanation, the transmitted power is assumed to be received as it is, but in consideration of the power transmission / reception efficiency, which is the ratio of the amount of electricity stored from the storage battery on the transmitting side to the amount of electricity stored increasing on the receiving side. It is desirable to put it in. (Step S104)
Since the mobile body 1 is determined to be the power receiving side based on the result of step S104, the control unit 11 proceeds to the power receiving operation step S109. (Step S105)
In the control unit 11, the power transmission / reception coil 5 receives wireless power from the moving body 2 as a power reception coil, the power transmission / reception circuit 3 rectifies and converts the voltage of the power received as the power reception circuit, and the power storage unit 7 receives power. Control so that electricity is stored. (Step S109)
The control unit 11 determines whether the power reception ends when the required power has been received or the power transmission from the power transmission side ends, and when the power reception does not end, the power reception operation is continued, and when the power reception ends, the power reception operation is continued. Proceed to the end operation. (Step S110)
The control unit 11 stops the power transmission / reception circuit. (Step S111)
By the above operation, the power receiving operation of the mobile body 1 is completed.

移動体２側の動作は、ステップＳ１０５まではほぼ同様で、送電側に判断されたステップＳ１０６に進んだ後の動作を以下で説明する。 The operation on the mobile body 2 side is almost the same up to step S105, and the operation after proceeding to step S106 determined by the power transmission side will be described below.

制御部１２は、蓄電部８の電力を使って、送受電回路４を送電回路に設定し、送受電コイル６から電力を送電する。（ステップＳ１０６）
制御部１２は、ステップＳ１０４で算出した指定の電力量を送電したかを判断する。指定量の送電が終わっていないときには送電動作を継続し、指定量の送電が終わった時にはステップＳ１０８へ進む。（ステップＳ１０７）
制御部１２は、送受電回路を制御して送電を停止する。（ステップＳ１０８）
以上の移動体１と移動体２の動作により、電池残量から充電の要求度を計算し、要求度が低い方から要求度が高い方へ、双方の要求度が一致する電力量の送電を行うことで、必要な電力量を必要な方へ送電することができる。
＜実施の形態２＞
図８に本発明の実施の形態２における双方向非接触電力伝送装置を備える移動体の構成を示す。図８の１～１４は実施の形態１の図１と同様であり、同じ動作をする部分は省略する。 The control unit 12 sets the power transmission / reception circuit 4 in the power transmission circuit by using the power of the power storage unit 8, and transmits power from the power transmission / reception coil 6. (Step S106)
The control unit 12 determines whether or not the designated electric power calculated in step S104 has been transmitted. When the designated amount of power transmission is not completed, the power transmission operation is continued, and when the designated amount of power transmission is completed, the process proceeds to step S108. (Step S107)
The control unit 12 controls the power transmission / reception circuit to stop power transmission. (Step S108)
By the above operation of the moving body 1 and the moving body 2, the demand for charging is calculated from the remaining battery level, and the power transmission of the same amount of power from the one with the lower demand to the one with the higher demand is transmitted. By doing so, the required amount of electric power can be transmitted to the required person.
<Embodiment 2>
FIG. 8 shows the configuration of a mobile body including the bidirectional non-contact power transmission device according to the second embodiment of the present invention. 1 to 14 of FIG. 8 are the same as those of FIG. 1 of the first embodiment, and a portion having the same operation is omitted.

位置情報検出部１５は、移動体１の現在位置の情報を検出する。ナビゲーションシステムとして広く使われているＧＰＳを使った現在位置の検出が好適に使える。 The position information detection unit 15 detects information on the current position of the moving body 1. The detection of the current position using GPS, which is widely used as a navigation system, can be preferably used.

制御部１１は、位置情報検出部１５が検出した現在位置と商用電源に接続された定置充電器までの距離を計算する。なお、定置充電器の位置情報は、既知の情報である。目標とする定置充電器は自宅や自社の保管場所に設置した定置充電器が考えらえるが、自分が契約している充電ステーションなども含めて、現在位置や目的に応じて手動や自動で選択を行っても良い。現在位置から定置充電器までの距離は、ナビゲーションシステムとして広く使われているような道路の経路を考慮して求めることができる。定置充電器までの必要走行距離は、実際に必要な走行距離よりも１０％などある程度の余裕をもって計算することが望ましい。 The control unit 11 calculates the distance between the current position detected by the position information detection unit 15 and the stationary charger connected to the commercial power supply. The position information of the stationary charger is known information. The target stationary charger can be a stationary charger installed at home or in your company's storage location, but you can manually or automatically select it according to your current location and purpose, including the charging station you have a contract with. May be done. The distance from the current position to the stationary charger can be determined by considering the road route that is widely used as a navigation system. It is desirable to calculate the required mileage to the stationary charger with a certain margin such as 10% of the actually required mileage.

制御部１１は計算した必要走行距離と蓄電部７の蓄電容量の情報などから移動体１がどれだけ充電されることを必要としているかの充電要求度を計算する。 The control unit 11 calculates the charging requirement of how much the mobile body 1 needs to be charged from the calculated required mileage and the information of the storage capacity of the storage unit 7.

図１２は本発明の実施の形態２における制御のフローチャートである。実施の形態１とステップ番号が同じステップについては同様の動作を行うため説明を省略する。 FIG. 12 is a flow chart of control according to the second embodiment of the present invention. Since the same operation is performed for the step having the same step number as that of the first embodiment, the description thereof will be omitted.

動作を開始したとき制御部１１は、位置情報検出部の情報から前記の手法などにより移動体１の必要走行距離を算出する。ここでは、図９の記載条件のように必要走行距離が６０ｋｍであったとする。同様に移動体２の制御部１２が算出する必要走行距離が１０ｋｍであったとする。（ステップＳ２０１）
次に制御部１１は、必要走行距離と蓄電残量から移動体１の充電要求度Ａを算出する。図９の記載条件では、残電力量が６０ｋＷｈで走行距離１ｋｍに必要な電力量が１ｋＷｈであるため、残走行距離が６０ｋｍである。このときの残走行距離と充電要求度の関係の一例として、図１０に示す関係を使うことができる。移動体１は必要走行距離が６０ｋｍであるため、６０ｋｍ以下の残走行距離最大の充電要求度である１００とし、６０ｋｍ以上を順次低減させている。移動体２についても同様に１０ｋｍ以下の走行距離は最大の充電要求度である１００とし、１０ｋｍ以上を順次低減させている。この残走行距離と充電要求度の関係を使用するとき、制御部１１は図１１のように移動体１の充電要求度を１００と算出する。同様に制御部１２は図１１のように移動体２の充電要求度を７０と算出する。（ステップＳ２０２）
以下のステップにおいて、実施の形態１と同様の動作を行うと、図１３ａのように送受電方向と送受電量は移動体１が受電側となり１０ｋＷｈの電力量を受電、移動体２が送電側となり１０ｋＷｈの電力量を送電する。送受電後は図１３ｂのように、移動体１の残電力量は７０ｋＷｈ、残走行距離は７０ｋｍ、充電要求度は８０となり、移動体２の残電力量は３０ｋＷｈ、残走行距離は３０ｋｍ、充電要求度は８０となる。 When the operation is started, the control unit 11 calculates the required mileage of the moving body 1 from the information of the position information detection unit by the above method or the like. Here, it is assumed that the required mileage is 60 km as described in FIG. Similarly, it is assumed that the required mileage calculated by the control unit 12 of the moving body 2 is 10 km. (Step S201)
Next, the control unit 11 calculates the charge request degree A of the mobile body 1 from the required mileage and the remaining charge. Under the conditions described in FIG. 9, since the remaining electric power is 60 kWh and the amount of electric power required for the traveling distance of 1 km is 1 kWh, the remaining traveling distance is 60 km. As an example of the relationship between the remaining mileage and the charging requirement at this time, the relationship shown in FIG. 10 can be used. Since the required mileage of the moving body 1 is 60 km, the charge requirement is set to 100, which is the maximum remaining mileage of 60 km or less, and the required mileage is gradually reduced to 60 km or more. Similarly, for the moving body 2, the mileage of 10 km or less is set to 100, which is the maximum charge requirement, and the mileage of 10 km or more is gradually reduced. When the relationship between the remaining mileage and the charging requirement is used, the control unit 11 calculates the charging requirement of the moving body 1 as 100 as shown in FIG. Similarly, the control unit 12 calculates the charging requirement of the mobile body 2 as 70 as shown in FIG. (Step S202)
In the following steps, when the same operation as that of the first embodiment is performed, as shown in FIG. 13a, the mobile body 1 is on the power receiving side and the mobile body 2 is on the power transmission side in terms of the power transmission / reception direction and the power transmission / reception amount. It transmits 10kWh of electric power. After power transmission / reception, as shown in FIG. 13b, the remaining power amount of the moving body 1 is 70kWh, the remaining mileage is 70km, the charging requirement is 80, the remaining power amount of the moving body 2 is 30kWh, the remaining mileage is 30km, and charging. The degree of requirement is 80.

以上の動作で、残電力量が少なく残走行距離が短いが充電要求度が低い移動体２から、残電力量が多く残走行距離が長いが充電要求度の高い移動体１へ送電が行われ、送受電後の充電要求度が等しくなって終了し、双方の充電要求度が一致する電力量の送電を行うことで、必要な電力量を必要な方へ送電することができる。
＜実施の形態３＞
図１４は本発明の実施の形態３における制御のフローチャートである。 By the above operation, power is transmitted from the moving body 2 having a small amount of remaining power and a short remaining mileage but having a low charge requirement to the moving body 1 having a large amount of remaining power and a long remaining mileage but having a high charge requirement. , The required amount of power can be transmitted to the required person by transmitting the amount of power in which the charging demands after power transmission / reception become equal and the charging demands of both sides match.
<Embodiment 3>
FIG. 14 is a flow chart of control according to the third embodiment of the present invention.

実施の形態２とステップ番号が同じステップについては同様の動作を行うため説明を省略する。必要走行距離、残電力量、走行距離１ｋｍに必要な電力量、残走行距離などの送受電前の状態も実施の形態２と同様とする。 Since the same operation is performed for the step having the same step number as that of the second embodiment, the description thereof will be omitted. The states before power transmission / reception such as the required mileage, the remaining power amount, the power amount required for the mileage of 1 km, and the remaining mileage are the same as those in the second embodiment.

実施の形態３において、制御部１１は、自移動体が受電時に対価として受電対価と、自移動体が送電時に対価として指定以上の対価を受け取る送電対価を設定するものとする。これらの対価は、全ての移動体で共通の値であっても良いし、移動体それぞれが個別に持っている値でも良いし、送受電を行うときに個別に入力するものであっても良いし、無線通信等によって外部から設定されるもので良い。 In the third embodiment, the control unit 11 sets a power receiving consideration as a consideration when the mobile body receives power and a power transmission consideration as a consideration when the mobile body receives power transmission. These consideration may be a value common to all mobiles, may be a value individually possessed by each mobile, or may be input individually when transmitting and receiving power. However, it may be set from the outside by wireless communication or the like.

ここでは、一例として移動体１と移動体２は図１５の受電対価と送電対価を持っているものとする。図１５の受電対価と送電対価は、移動体１は受電対価ＲＡとして１５０円／ｋＷｈ以下であれば受電を行い、送電対価ＴＡとして１００円／ｋＷｈ以上であれば送電を行い、移動体２は受電対価ＲＢとして１３０円／ｋＷｈ以下であれば受電を行い、送電対価ＴＢとして１２０円／ｋＷｈ以上であれば送電を行うことを示している。 Here, as an example, it is assumed that the mobile body 1 and the mobile body 2 have the power receiving consideration and the power transmission consideration in FIG. Regarding the power receiving consideration and the power transmission consideration in FIG. 15, the mobile body 1 receives power if the power receiving consideration RA is 150 yen / kWh or less, and the mobile body 2 transmits power if the power transmission consideration TA is 100 yen / kWh or more. If the power receiving consideration RB is 130 yen / kWh or less, power is received, and if the power transmission consideration TB is 120 yen / kWh or more, power transmission is performed.

移動体１と移動体２の間で充放電動作を開始したとき、実施の形態２と同様の動作を行う。（ステップＳ２０１、Ｓ２０２）
次に、制御部１１は、通信部１３を使って移動体１側の充電要求度Ａとして１００と、移動体１の受電対価ＲＡとして１５０と、移動体１の送電対価ＴＡとして１００を通信で送信する。また、移動体２側の充電要求度Ｂである２０と、移動体２の受電対価ＲＢとして１３０と、移動体２の送電対価ＴＢとして１２０を通信で受信する。（ステップＳ３０１）
実施の形態２と同様に、移動体１の要求度と受電対価と送電対価が移動体２側へ、移動体２の要求度と受電対価と送電対価が移動体１へ通信が完了しているか確認をし、通信が完了したら送電側になるか受電側になるかと、送電電力量を算出する。（ステップＳ１０３、ステップＳ１０４）
送電側の送電対価と受電側の受電対価を比較し、送電側の受電対価が受電側の受電対価以上であるときはステップＳ１０５以降の送受電動作を行う。送電側の受電対価が受電側の受電対価未満の時は、送電対価と受電対価の交渉が成立しなかったので、終了する。（ステップＳ３０２）
この例では、移動体１が受電側となり、移動体２が送電側となり、移動体１は１ｋＷｈあたり１５０円以下であれば受電を行い、移動体２は１ｋＷｈあたり１２０円以上であれば送電を行う条件であるＴＢ（１２０円／ｋＷｈ）≦ＲＡ（１５０円／ｋＷｈ）が成立し、送受電動作を行う。 When the charging / discharging operation is started between the moving body 1 and the moving body 2, the same operation as that of the second embodiment is performed. (Steps S201, S202)
Next, the control unit 11 uses the communication unit 13 to communicate 100 as the charge request degree A on the mobile body 1 side, 150 as the power receiving consideration RA of the mobile body 1, and 100 as the power transmission consideration TA of the mobile body 1. Send. Further, the charging request degree B 20 on the mobile body 2 side, 130 as the power receiving consideration RB of the mobile body 2, and 120 as the power transmission consideration TB of the mobile body 2 are received by communication. (Step S301)
As in the second embodiment, whether the requirement of the mobile body 1, the power receiving consideration and the power transmission consideration have been communicated to the mobile body 2 side, and the requirement of the mobile body 2 and the power receiving consideration and the power transmission consideration have been communicated to the mobile body 1. Confirm and calculate the amount of power transmitted, whether it will be the power transmission side or the power reception side when communication is completed. (Step S103, Step S104)
The power transmission consideration on the power transmission side and the power reception price on the power reception side are compared, and when the power reception price on the power transmission side is equal to or higher than the power reception price on the power reception side, the power transmission / reception operation after step S105 is performed. When the power reception consideration on the power transmission side is less than the power reception price on the power reception side, negotiations between the power transmission price and the power reception price have not been established, so the process ends. (Step S302)
In this example, the mobile body 1 is the power receiving side, the mobile body 2 is the power transmitting side, the mobile body 1 receives power if it is 150 yen or less per 1 kWh, and the mobile body 2 transmits power if it is 120 yen or more per 1 kWh. TB (120 yen / kWh) ≤ RA (150 yen / kWh), which is the condition to be performed, is satisfied, and the power transmission / reception operation is performed.

このときの対価は送電対価以上受電対価以下であればよく、送電対価や受電対価や送電対価と受電対価の平均などを使うことができる。 The consideration at this time may be equal to or greater than the transmission consideration and less than or equal to the power reception consideration, and the transmission consideration, the power reception consideration, the average of the transmission consideration and the power reception consideration, etc. can be used.

移動体１と移動体２の間の対価のやりとりは、直接金銭のやり取りを行っても良いし、オンラインの決済であってもよいし、ポイントのようなもののやり取りであっても良い。 The exchange of consideration between the mobile body 1 and the mobile body 2 may be a direct exchange of money, an online payment, or an exchange of something like points.

以上の動作で、残電力量が少なく残走行距離が短いが充電要求度が低い移動体２から、残電力量が多く残走行距離が長いが充電要求度の高い移動体１へ送電が行われ、送受電後の充電要求度が等しくなって終了し、双方の充電要求度が一致する電力量の送電を行うことで、必要な電力量を必要な方へ送電することができ、かつ送電側の送電対価と受電側の受電対価を満たした充放電を行うことができる。
＜実施の形態４＞
図１６は本発明の実施の形態４における制御のフローチャートである。 By the above operation, power is transmitted from the moving body 2 having a small amount of remaining power and a short remaining mileage but having a low charging requirement to the moving body 1 having a large amount of remaining power and a long remaining mileage but having a high charging requirement. , The required amount of power can be transmitted to the required person by transmitting the amount of power that ends when the charging requirements after power transmission and reception become equal and the charging requirements of both sides match, and the power transmission side. It is possible to charge and discharge the power transmission consideration and the power reception consideration on the power receiving side.
<Embodiment 4>
FIG. 16 is a flow chart of control according to the fourth embodiment of the present invention.

実施の形態３とステップ番号が同じステップについては同様の動作を行うため説明を省略する。 Since the same operation is performed for the step having the same step number as that of the third embodiment, the description thereof will be omitted.

移動体１と移動体２の間で充放電動作を開始したとき、実施の形態２と同様の動作を行う。（ステップＳ２０１、Ｓ２０２）
次に、制御部１１は、通信部１３を使って移動体１側の充電要求度Ａとして１００と、移動体１の受電対価ＲＡとして１５０と、移動体１の送電対価ＴＡとして１００を通信で送信する。また、複数の移動体の充電要求度と、受電対価と送電対価を通信で受信する。複数の移動体との通信は異なる相手が見つからなくなるまで確認を続けても良いし、一定時間で区切っても良い。また、通信相手の上限数を設けても良い（ステップＳ４０１）
実施の形態３と同様に、移動体１の要求度と受電対価と送電対価が相手側移動体へ、複数の移動体の要求度と受電対価と送電対価が移動体１へ通信が完了しているか確認をし、通信が完了したら複数の移動体との要求度の比較を行い送電側になるか受電側になるかと、送電電力量を算出する。（ステップＳ１０３、ステップＳ１０４）
送電側は、受電側が複数の場合は受電対価が最大の移動体を選択する。受電側は、送電側が複数の場合は送電対価が最小の移動体を選択する。 When the charging / discharging operation is started between the moving body 1 and the moving body 2, the same operation as that of the second embodiment is performed. (Steps S201, S202)
Next, the control unit 11 uses the communication unit 13 to communicate 100 as the charge request degree A on the mobile body 1 side, 150 as the power receiving consideration RA of the mobile body 1, and 100 as the power transmission consideration TA of the mobile body 1. Send. In addition, the charging request degree of a plurality of mobile bodies, and the power receiving consideration and the power transmission consideration are received by communication. Communication with a plurality of mobile objects may be continued until a different partner cannot be found, or may be separated by a certain period of time. Further, an upper limit number of communication partners may be set (step S401).
Similar to the third embodiment, the communication of the requirement of the mobile body 1, the power receiving consideration and the power transmission consideration to the other mobile body is completed, and the communication of the requirements of the plurality of mobile bodies, the power receiving consideration and the power transmission consideration to the mobile body 1 is completed. When communication is completed, the degree of demand is compared with multiple mobiles, and the amount of power transmitted is calculated as to whether it will be the power transmission side or the power reception side. (Step S103, Step S104)
If there are multiple power receiving sides, the power transmitting side selects the mobile unit with the highest power receiving consideration. If there are multiple power transmission sides, the power receiving side selects the mobile unit with the lowest power transmission consideration.

一例として、３台の移動体間での送受電方向と受電対価と送電対価が図１７の場合を想定する。必要走行距離、残電力量、走行距離１ｋｍに必要な電力量、残走行距離および充電要求度の計算は省略するが、実施の形態３と同様の計算を行い、その結果が図１７の送受電方向となっているものとする。 As an example, it is assumed that the power transmission / reception direction, the power reception consideration, and the transmission consideration between the three mobile units are shown in FIG. Although the calculation of the required mileage, the remaining electric energy, the electric energy required for the mileage of 1 km, the remaining mileage, and the charging requirement is omitted, the same calculation as in the third embodiment is performed, and the result is the power transmission / reception in FIG. It shall be the direction.

移動体１が送電側、移動体２と移動体３が受電側となったため、移動体１は受電対価が最大のＲＣ：１４０円／ｋＷｈである移動体３を選択する。移動体２と移動体３は、送電側が移動体１の１台しかないため送電対価が最小のＴＡ：１００円／ｋＷｈである移動体１を選択する。（ステップＳ４０２）
移動体１は相手側として移動体３から選択され、送電側の移動体１の送電対価１００≦受電側の移動体３の受電対価１４０であるので、次のステップＳ１０５へ進む。移動体３は相手側として移動体１から選択され、送電側の移動体１の送電対価１００≦受電側の移動体３の受電対価１４０であるので、次のステップＳ１０５へ進む。移動体２は相手側から選択されなかったので動作を終了する。（ステップＳ４０３）
別の例として、３台の移動体間での送受電方向と受電対価と送電対価が図１８の場合を想定する。 Since the mobile body 1 is on the power transmission side and the mobile body 2 and the mobile body 3 are on the power receiving side, the mobile body 1 selects the mobile body 3 having the maximum power receiving consideration of RC: 140 yen / kWh. As the mobile body 2 and the mobile body 3, since there is only one mobile body 1 on the power transmission side, the mobile body 1 having the minimum power transmission consideration of TA: 100 yen / kWh is selected. (Step S402)
Since the mobile body 1 is selected from the mobile body 3 as the other side and the power transmission consideration of the mobile body 1 on the power transmission side is 100 ≦ the power reception price 140 of the mobile body 3 on the power reception side, the process proceeds to the next step S105. Since the mobile body 3 is selected from the mobile body 1 as the other side and the power transmission consideration of the mobile body 1 on the power transmission side is 100 ≦ the power reception price 140 of the mobile body 3 on the power reception side, the process proceeds to the next step S105. Since the mobile body 2 is not selected by the other party, the operation ends. (Step S403)
As another example, it is assumed that the power transmission / reception direction, the power reception consideration, and the transmission consideration between the three mobile units are shown in FIG.

移動体１が受電側、移動体２と移動体３が送電側となったため、移動体１は送電対価が最小のＴＣ：１００円／ｋＷｈである移動体３を選択する。移動体２と移動体３は、受電側が移動体１の１台しかないため受電対価が最大のＲＡ：１５０円／ｋＷｈ移動体１を選択する。（ステップＳ４０２）
移動体１は相手側として移動体３から選択され、送電側の移動体３の送電対価１００≦受電側の移動体１の受電対価１５０であるので、次のステップＳ１０５へ進む。移動体３は相手側として移動体１から選択され、送電側の移動体３の送電対価１００≦受電側の移動体１の受電対価１５０であるので、次のステップＳ１０５へ進む。移動体２は相手側から選択されなかったので動作を終了する。（ステップＳ４０３）
ここでは例として移動体を３台としたが、台数が多いときには移動体間での通信によらず、サーバーコンピュータ等を用いて送受電の対象を同様の方法で求めることもできる。また、送電側が複数かつ受電側が複数で、送受電の組の成立の計算が困難なときには、先着順に決定したり、送電対価や受電対価によって優先順位を付けて決めることもできる。 Since the mobile body 1 is on the power receiving side and the mobile body 2 and the mobile body 3 are on the power transmission side, the mobile body 1 selects the mobile body 3 having the minimum TC: 100 yen / kWh. As the mobile body 2 and the mobile body 3, since there is only one mobile body 1 on the power receiving side, RA: 150 yen / kWh mobile body 1 having the maximum power receiving consideration is selected. (Step S402)
Since the mobile body 1 is selected from the mobile body 3 as the other side and the power transmission consideration of the mobile body 3 on the power transmission side is 100 ≦ the power reception price of the mobile body 1 on the power reception side is 150, the process proceeds to the next step S105. Since the mobile body 3 is selected from the mobile body 1 as the other side and the power transmission consideration of the mobile body 3 on the power transmission side is 100 ≦ the power reception price of the mobile body 1 on the power reception side is 150, the process proceeds to the next step S105. Since the mobile body 2 is not selected by the other party, the operation ends. (Step S403)
Here, three mobile units are used as an example, but when the number of mobile units is large, the target of power transmission / reception can be obtained by the same method using a server computer or the like, regardless of communication between the mobile units. Further, when there are a plurality of power transmission sides and a plurality of power reception sides and it is difficult to calculate the formation of a power transmission / reception pair, the power transmission / reception pair can be determined on a first-come, first-served basis, or can be prioritized according to the power transmission consideration or the power reception consideration.

以上の動作で、他移動体から受電を受けようとする移動体が複数あるとき
もっとも高い受電対価を設定した移動体に対しその受電対価で送電を行い、
他移動体へ送電を行える移動体が複数あるときもっとも安い送電対価を設定した移動体からその送電対価で受電を行うことができる。 With the above operation, when there are multiple mobiles that are going to receive power from other mobiles, power is transmitted to the mobile that has the highest power receiving consideration at that power receiving consideration.
When there are multiple mobiles that can transmit power to other mobiles, it is possible to receive power from the mobile that has the cheapest power transmission consideration.

本発明の双方向非接触電力伝送装置を備える移動体は、蓄電した電力を移動に使う移動体間で双方向に電力伝送を行う産業分野に利用することができる。 The mobile body provided with the bidirectional non-contact power transmission device of the present invention can be used in an industrial field in which power is transmitted in both directions between mobile bodies that use stored power for movement.
