Description

本発明は、電気自動車（ＥＶ）等の電動モビリティへの急速充電を可能とする急速充電ステーションに関する。 The present invention relates to a quick charging station that enables quick charging of electric mobility such as an electric vehicle (EV).

環境問題の点から電動モビリティ、特に電気自動車の普及が図られている。電気自動車の普及を促進させるには、電気自動車への追加充電を迅速に行うことを可能とする急速充電施設の普及が必要となる。 From the viewpoint of environmental problems, electric mobility, especially electric vehicles, has been popularized. In order to promote the spread of electric vehicles, it is necessary to spread a quick charging facility that can quickly perform additional charging of electric vehicles.

一方、系統電源により電気自動車一台を８０％以上に充電するためは、一般的に、低圧受電設備による１００Ｖの普通充電では十数時間以上が必要となり、２００Ｖの普通充電でも数時間以上が必要となる。５０ｋＷ以上の高圧受電設備による急速充電では１５〜３０分程度で充電することができるが、高圧受電設備の設置にはコストがかかる。 On the other hand, in order to charge one electric vehicle to 80% or more by the system power supply, generally, it takes more than ten hours for 100V normal charging by the low voltage power receiving equipment, and several hours for 200V normal charging. Becomes Fast charging by a high-voltage power receiving facility of 50 kW or more can be charged in about 15 to 30 minutes, but installation of the high-voltage power receiving facility is costly.

これに対し、高圧受電設備を新設または増強することなく、受電設備のない山間部などにおいても急速充電を可能とするため、ディーゼルエンジンによるエンジン駆動発電機を急速充電器に接続することが提案されている（特許文献１）。 On the other hand, it is proposed to connect an engine-driven generator with a diesel engine to a quick charger in order to enable quick charging even in mountainous areas where there is no power receiving equipment, without newly installing or augmenting high-voltage receiving equipment. (Patent Document 1).

また、系統電源からも、蓄電ユニットに接続した再生可能エネルギー発電ユニットからも、水素ガスを燃料とした燃料電池または内燃機関による水素発電ユニットからも、電気自動車に電力を供給できるようにした電力供給システムが提案されている（特許文献２）。 In addition, power supply that can supply power to the electric vehicle from the system power supply, the renewable energy power generation unit connected to the power storage unit, the hydrogen power generation unit using a fuel cell using hydrogen gas as a fuel, or the internal combustion engine. A system has been proposed (Patent Document 2).

実用新案登録第３１９５８０６号公報Utility model registration No. 3195806 特許第６００５５０３号公報Japanese Patent No. 6500503

しかしながら、特許文献１には、ディーゼルエンジンによる発電機を駆動させるための軽油を、該発電機にどのように蓄えておくかについては記載されておらず、たとえば、災害時などにおいて道路網が寸断され、ガソリンスタンドでディーゼルエンジン発電機に軽油を供給することができない場合には急速充電器も機能しなくなる。 However, Patent Document 1 does not describe how to store light oil for driving a generator of a diesel engine in the generator. For example, the road network is cut off in the event of a disaster. If the gas station cannot supply light oil to the diesel engine generator, the quick charger also fails.

また、特許文献２の電力供給システムによれば、災害時に系統電源からの電力供給が途絶えた場合でも、蓄電ユニットを備えた再生可能エネルギー発電ユニット、又は水素発電ユニットからの電力が使用できるとされている。しかしながら、蓄電ユニットを備えていても、この蓄電ユニットは再生可能エネルギーによる電力を蓄電するものであるため、系統電源が途絶えた場合に再生可能エネルギーが引き続き供給されたとしても複数台の電気自動車に同時に急速充電を安定して行えるようにすることは困難である。また、水素発電ユニットへ外部から水素を供給する手段はタンクローリーやパイプラインとされているので、水素発電ユニットへ水素ガスを供給できる地域が限定的となる。そのため、災害時でなくても、地域によっては水素発電ユニットで使用する水素を十分に確保できないことが懸念される。 Further, according to the power supply system of Patent Document 2, even if the power supply from the system power supply is interrupted in the event of a disaster, the power from the renewable energy power generation unit including the power storage unit or the hydrogen power generation unit can be used. ing. However, even if a power storage unit is provided, this power storage unit stores electric power from renewable energy, so even if the renewable energy continues to be supplied to multiple electric vehicles when the system power supply is cut off. At the same time, it is difficult to stably perform rapid charging. Further, since the means for supplying hydrogen from the outside to the hydrogen power generation unit is a tank truck or a pipeline, the area where hydrogen gas can be supplied to the hydrogen power generation unit is limited. Therefore, there is a concern that hydrogen used in the hydrogen power generation unit may not be sufficiently secured in some regions even when there is no disaster.

これに対し、本発明は、道路網が発達していない地域や、災害などで道路網が寸断された地域などにおいても、燃料ガスを用いた発電機による電力を用いて大容量の急速充電を可能とし、例えば、複数台の電気自動車に確実に急速充電をできるようにすることを課題とする。 On the other hand, the present invention enables large-capacity rapid charging by using electric power from a generator that uses fuel gas, even in an area where the road network is not developed or where the road network is fragmented due to a disaster or the like. It is an object of the present invention to make it possible, for example, to surely perform rapid charging for a plurality of electric vehicles.

本発明者は、電動モビリティに急速充電を行う急速充電ステーションに内燃力発電機を備えるにあたり、内燃力発電機で使用できる燃料ガスの種類にフレキシビリティを持たせ、かつ、内燃力発電機で使用する燃料ガスを移動式ボンベとして貯蔵し、内燃力発電機から供給される電力を蓄電器に蓄電することにより上述の課題を達成できることを想到し、本発明を完成させた。 The present inventor, when providing an internal combustion power generator in a quick charging station for performing rapid charging for electric mobility, has flexibility in the types of fuel gas that can be used in the internal combustion power generator, and uses it in the internal combustion power generator. The present invention has been completed based on the idea that the above-described problems can be achieved by storing the fuel gas as a mobile cylinder and storing the electric power supplied from the internal combustion power generator in a battery.

即ち、本発明は、電動モビリティに急速充電を行う急速充電ステーションであって、
複数種の燃料ガスが貯蔵される燃料ガス貯蔵部、
複数種の燃料ガスを切り替えて供給し得る内燃力発電機、
内燃力発電機と燃料ガス貯蔵部の間に設けられたレギュレータ、

A power storage device that stores the electric power supplied from the internal combustion power generator, and
Has a quick charger connected to the battery,
A fuel gas reservoir provides a quick charging station with a mobile cylinder of fuel gas.

本発明の急速充電ステーションは、複数種の燃料ガスを切り替えて供給し得る内燃力発電機を有し、内燃力発電機を駆動する燃料ガスにフレキシビリティがあるので、特定の燃料ガスを内燃力発電機に供給できない場合でも他の燃料ガスによって内燃力発電機を駆動させることが可能となる。 The quick charging station of the present invention has an internal combustion power generator capable of switching and supplying a plurality of types of fuel gas, and since the fuel gas that drives the internal combustion power generator has flexibility, a specific fuel gas can be supplied to the internal combustion power generator. Even if the power cannot be supplied to the generator, the internal combustion power generator can be driven by another fuel gas.

また、内燃力発電機を駆動する燃料ガスが移動式ボンベにより貯蔵されるので、急速充電ステーションに所望量の燃料ガスを簡便に備蓄することができ、かつ道路網が発達していない地域や災害などで道路網が寸断された地域などにおいても燃料ガスを急速充電ステーションに補充することが容易となる。 In addition, since the fuel gas that drives the internal combustion power generator is stored by the mobile cylinder, it is possible to easily store a desired amount of fuel gas in the quick charging station, and areas or disasters where the road network is not developed. It becomes easy to replenish the fuel gas to the quick charging station even in an area where the road network is fragmented due to such reasons.

図面を参照しつつ本発明を詳細に説明する。なお、各図中、同一符号は同一または同等の構成要素を表している。 The present invention will be described in detail with reference to the drawings. In each drawing, the same reference numerals represent the same or equivalent constituent elements.

（全体構成）
図１は、本発明の一実施例の急速充電ステーション１Ａの概略構成図である。この急速充電ステーション１Ａは、電気自動車に急速充電を行う急速充電器２を備え、ＥＶステーションとして機能する。急速充電器２は複数備えられており、各急速充電器２には蓄電器３が接続されている。 (overall structure)
FIG. 1 is a schematic configuration diagram of a quick charging station 1A according to an embodiment of the present invention. This quick charging station 1A includes a quick charger 2 that charges an electric vehicle rapidly, and functions as an EV station. A plurality of quick chargers 2 are provided, and a capacitor 3 is connected to each quick charger 2.

急速充電ステーション１Ａは電力源として内燃力発電機４を有しており、内燃力発電機４は、そこに複数種の燃料ガスが切り替えられて供給されても発電可能となっている。一方、急速充電ステーション１Ａには、必要に応じて燃料電池５を設けても良く、また、急速充電ステーション１Ａの設置場所が系統電源から電力を受電できる場合には、系統電源６から蓄電器３に電力を蓄電できるように、系統電源との接続部を設けておくことが好ましい。 The quick charging station 1A has an internal combustion power generator 4 as an electric power source, and the internal combustion power generator 4 can generate power even if a plurality of types of fuel gas are switched and supplied thereto. On the other hand, the quick charging station 1A may be provided with the fuel cell 5 if necessary. Further, if the location where the quick charging station 1A is installed can receive power from the system power supply, the system power supply 6 causes the battery 3 to be stored. It is preferable to provide a connecting portion with a system power source so that electric power can be stored.

（内燃力発電機）
本発明の急速充電ステーション１Ａは内燃力発電機４を備えている。内燃力発電機４は、環境負荷は燃料電池よりも大きいが、低価格で設置することができる。また、内燃力発電機４で使用する燃料ガスは、燃料電池５で使用する燃料ガスほど高純度であることが不要である。したがって、急速充電ステーションを普及させ、それにより電気自動車等の電動モビリティの普及を支えるためには、急速充電ステーションの電力源として内燃力発電機４を使用することが好ましい。 (Internal combustion power generator)
The quick charging station 1A of the present invention includes an internal combustion power generator 4. The internal combustion power generator 4 has a larger environmental load than the fuel cell, but can be installed at a low price. Further, the fuel gas used in the internal combustion power generator 4 does not need to be as pure as the fuel gas used in the fuel cell 5. Therefore, in order to popularize the rapid charging station and thereby support the popularization of electric mobility of electric vehicles and the like, it is preferable to use the internal combustion power generator 4 as a power source of the rapid charging station.

内燃力発電機４としては、ロータリーエンジン、レシプロエンジン、ガスタービン等を挙げることができる。中でも、多様な燃料ガスに対応させやすい点からはロータリーエンジンが好ましく、また、高い発電量を得る点からはレシプロエンジンが好ましい。 Examples of the internal combustion power generator 4 include a rotary engine, a reciprocating engine, a gas turbine and the like. Among them, the rotary engine is preferable from the viewpoint of easily adapting to various fuel gases, and the reciprocating engine is preferable from the viewpoint of obtaining a high power generation amount.

内燃力発電機４の発電量としては、例えば出力が３〜１００ｋＷあればよく、より好ましくは３〜２００ｋＷである。
内燃力発電機４には複数種の燃料ガスを切り替えて供給することが可能となっている。 The amount of power generated by the internal combustion power generator 4 may be, for example, an output of 3 to 100 kW, and more preferably 3 to 200 kW.
A plurality of types of fuel gas can be switched and supplied to the internal combustion power generator 4.

（燃料ガス）
内燃力発電器４に供給される燃料ガスとしては、例えば、オフサイト水素ガス等の水素ガス、都市ガス、プロパンガス、バイオガスなどを挙げることができ、水素ガスは、高圧水素ボンベとして備えてもよく、水素吸蔵合金として備えてもよい。 (Fuel gas)
Examples of the fuel gas supplied to the internal combustion power generator 4 include hydrogen gas such as off-site hydrogen gas, city gas, propane gas, biogas, etc. The hydrogen gas is provided as a high-pressure hydrogen cylinder. Alternatively, it may be provided as a hydrogen storage alloy.

これらの燃料ガスは移動式ボンベにより燃料ガス貯蔵部７に備えられる。ここで、移動式ボンベとは移動可能な高圧ガス容器をいい、個々の高圧ガス容器ごとに移動可能であってもよく、複数の高圧ガス容器が束ねられて共通のバルブで開閉するバンドルであってもよい。燃料ガスを移動式ボンベとして備えることにより、急速充電ステーション１Ａに所望量の燃料ガスを簡便に備蓄することができる。燃料ガスごとに複数個の移動式ボンベを備蓄してもよい。水素の移動式ボンベとしては、高圧ガス保安法に抵触しない水素吸蔵合金が好ましい。このような水素吸蔵合金としては、例えば（株）日本製鋼所の水素吸蔵合金を使用することができる。 These fuel gases are provided in the fuel gas storage unit 7 by a mobile cylinder. Here, the movable cylinder refers to a movable high-pressure gas container, may be movable for each individual high-pressure gas container, and is a bundle in which a plurality of high-pressure gas containers are bundled and opened and closed by a common valve. May be. By providing the fuel gas as a movable cylinder, a desired amount of fuel gas can be easily stored in the quick charging station 1A. A plurality of mobile cylinders may be stocked for each fuel gas. As the hydrogen transfer cylinder, a hydrogen storage alloy that does not conflict with the high pressure gas safety method is preferable. As such a hydrogen storage alloy, for example, a hydrogen storage alloy manufactured by Nippon Steel Works, Ltd. can be used.

また、移動式ボンベ自体は容易に搬送できる。したがって、移動式ボンベ内の燃料ガスが空になった場合には、空の移動式ボンベと満充填されている移動式ボンベとを入れ替えることにより、タンクローリー等の特殊車両がなくても、パイプラインが設置されていなくても、燃料ガス貯蔵部７に容易に燃料ガスを補充することができる。特に、移動式ボンベとしてバンドルを使用すると、燃料ガスの貯蔵や、搬送をより簡便に行うことができる。 Further, the movable cylinder itself can be easily transported. Therefore, when the fuel gas in the mobile cylinder becomes empty, the empty mobile cylinder can be replaced with a fully-filled mobile cylinder to eliminate the need for special vehicles such as tank trucks. Even if the fuel gas storage unit 7 is not installed, the fuel gas can be easily replenished to the fuel gas storage unit 7. In particular, when the bundle is used as the movable cylinder, the fuel gas can be stored and transported more easily.

急速充電ステーション１Ａでは、上述の燃料ガスの２種以上を切り替えて使用できるようにしておくことが好ましい。災害時等においては、燃料ガスの種類によって補充可能または不能となることが懸念されるが、複数種の燃料ガスを切り替えて使用できるようにすることにより、補充可能な燃料ガスを用いて急速充電ステーションを稼働させることができる。 In the rapid charging station 1A, it is preferable that two or more kinds of the above-mentioned fuel gas can be switched and used. In the event of a disaster, there is a concern that refueling may or may not be possible depending on the type of fuel gas, but by enabling multiple types of fuel gas to be switched and used, quick charging using replenishable fuel gas is possible. The station can be operated.

一方、内燃力発電機４では燃料ガスの種類により最適な流量が異なる。そこで、複数種の燃料ガスを共通の内燃力発電機４で使用できるようにするため、図２に示すように、各燃料ガスの移動式ボンベ８と内燃力発電機４との間に該内燃力発電機４への燃料ガスの流量を調整するレギュレータ９を設けることが好ましい。 On the other hand, in the internal combustion power generator 4, the optimum flow rate differs depending on the type of fuel gas. Therefore, in order to make it possible to use a plurality of types of fuel gas in the common internal combustion power generator 4, as shown in FIG. 2, the internal combustion power generator 4 is provided between the movable cylinder 8 for each fuel gas and the internal combustion power generator 4. It is preferable to provide a regulator 9 for adjusting the flow rate of the fuel gas to the power generator 4.

また、図２に示すように、各燃料ガスの移動式ボンベ８としてボンベバンドルを設けた場合、ボンベバンドルとレギュレータ９の間には、切替弁１０を設け、ボンベバンドル８内の燃料ガスの圧力を圧力計１１で常時監視できるようにすることが好ましい。これにより、内燃力発電機４に燃料ガスを供給しているボンベバンドル８の圧力計１１で測定された圧力が所定の圧力を下回ったら、他の待機中のボンベバンドル８から内燃力発電機４へ燃料ガスが供給されるように切替弁１０を切り替えることができる。なお、圧力計１１は無線操作で常時観察できるようにすることが好ましく、切替弁１０における切替操作は、圧力計１１で計測された圧力に基づいて自動で制御できるようにすることが好ましい。 Further, as shown in FIG. 2, when a cylinder bundle is provided as the movable cylinder 8 for each fuel gas, a switching valve 10 is provided between the cylinder bundle and the regulator 9 so that the pressure of the fuel gas in the cylinder bundle 8 is reduced. Is preferably constantly monitored by the pressure gauge 11. As a result, when the pressure measured by the pressure gauge 11 of the cylinder bundle 8 that supplies the fuel gas to the internal combustion power generator 4 falls below a predetermined pressure, another internal cylinder bundle 8 waits for the internal combustion power generator 4 to wait. The switching valve 10 can be switched so that the fuel gas is supplied to. It is preferable that the pressure gauge 11 can be constantly observed by wireless operation, and that the switching operation of the switching valve 10 can be automatically controlled based on the pressure measured by the pressure gauge 11.

一方、流量が燃料ガスの種類に応じて自動調整されるようにする場合には、図１Ｂに示すように、複数種の燃料ガスに対して一つのレギュレータ９を設けても良い。 On the other hand, when the flow rate is automatically adjusted according to the type of fuel gas, one regulator 9 may be provided for a plurality of types of fuel gas, as shown in FIG. 1B.

また、燃料ガスとしては、風力、太陽光などを使用して発電した再生可能エネルギー１３で水を電気分解することにより水素ガスを発生させ、これを内燃力発電機４に供給してもよい。また、都市ガスの配管網が整備されている地域では、移動式ボンベに加えて、都市ガスの配管との接続バルブを設けてもよい。 Further, as the fuel gas, hydrogen gas may be generated by electrolyzing water with the renewable energy 13 generated using wind power, sunlight, etc., and this may be supplied to the internal combustion power generator 4. In addition, in an area where the city gas piping network is maintained, a connection valve for connecting to the city gas piping may be provided in addition to the mobile cylinder.

（燃料電池）
燃料電池５で電力を得ると、内燃力発電機４で電力を得る場合に比して環境負荷を小さくすることができる。燃料電池５にも複数種の燃料ガスを切り替えて供給することができる。しかしながら、燃料電池５は内燃力発電機４に比して導入コストが高く、寿命が短く、燃料電池で燃料ガスとして使用する水素ガスは、内燃力発電機４で使用する水素ガスに比して高純度であることが必要とされる。そのため、本発明において、燃料電池５は必要に応じて設けられる。 (Fuel cell)
When the fuel cell 5 obtains electric power, the environmental load can be reduced as compared with the case where the internal combustion power generator 4 obtains electric power. A plurality of types of fuel gas can be switched and supplied to the fuel cell 5 as well. However, the fuel cell 5 has a higher introduction cost and a shorter life than the internal combustion power generator 4, and the hydrogen gas used as the fuel gas in the fuel cell is higher than the hydrogen gas used in the internal power generator 4. High purity is required. Therefore, in the present invention, the fuel cell 5 is provided as needed.

燃料電池５に供給する水素ガスとしては、上述の都市ガス、プロパンガス、又はバイオガスを、改質器１２に通すことにより得られるオンサイト水素ガスを使用することができ、必要に応じて精製処理を行う。この場合、改質器１２としては、公知のオンサイト型水素ステーションで使用されているものを使用することができ、例えば、三菱化工機（株）の水蒸気改質水素製造装置を使用することができる。また、燃料電池５に供給する水素ガスとして、再生可能エネルギーを用いて水を電気分解することにより得た水素ガスを用いても良く、オフサイト水素ガスを用いても良い。 As the hydrogen gas supplied to the fuel cell 5, on-site hydrogen gas obtained by passing the above-mentioned city gas, propane gas, or biogas through the reformer 12 can be used, and refined as necessary. Perform processing. In this case, as the reformer 12, a reformer 12 used in a known on-site hydrogen station can be used. For example, a steam reforming hydrogen production device manufactured by Mitsubishi Kakoki Co., Ltd. it can. Further, as the hydrogen gas supplied to the fuel cell 5, hydrogen gas obtained by electrolyzing water using renewable energy may be used, or off-site hydrogen gas may be used.

（系統電源）
系統電源６としては、高圧引込、低圧引込のいずれによってもよく、受電設備のないところでは、系統電源６を使用することは必ずしも必要ではない。ただし、既存設備として受電設備のあるところでは、その受電設備を使用し、蓄電器３に電力を蓄電することが好ましい。特に、高圧受電設備のあるところでは、充填時間を短縮するためにＡ／Ｄ変換器を介して系統電源６と蓄電器３とを接続することが好ましい。 (System power supply)
The system power supply 6 may be either a high-voltage power supply or a low-voltage power supply, and it is not always necessary to use the system power supply 6 where there is no power receiving facility. However, where there is a power receiving facility as an existing facility, it is preferable to use the power receiving facility and store electric power in the battery 3. In particular, where there is high-voltage power receiving equipment, it is preferable to connect the system power supply 6 and the storage battery 3 via an A/D converter in order to shorten the filling time.

（再生可能エネルギー）
本発明においては、電力源として再生可能エネルギー１３を使用し、それを蓄電器３に蓄電してもよい。再生可能エネルギー１３としては、風力発電、太陽光発電等によるものを挙げることができる。 (Renewable energy)
In the present invention, the renewable energy 13 may be used as a power source and stored in the battery 3. Examples of the renewable energy 13 include wind power generation, solar power generation, and the like.

ただし、再生可能エネルギー１３の発電量は一定せず、大がかりな設備が必要となるため、本発明において再生可能エネルギーは既存設備を利用できる場合に使用することが好ましい。 However, since the amount of power generated by the renewable energy 13 is not constant and large-scale equipment is required, it is preferable to use renewable energy in the present invention when existing equipment can be used.

（蓄電器）
蓄電器３としてはリチウムイオン蓄電器、鉛蓄電器、ナトリウム硫黄蓄電池、全固体電池、リチウム空気電池、フライホイールなどを使用することができる。複数台の電気自動車等の電動モビリティに対して急速充電を可能とする点から、蓄電器３としては大容量のものを設けることが好ましく、例えば１０〜２００ｋＷｈ、より好ましくは１５０〜２００ｋＷｈの蓄電器を設けることができる。また、同様の点から蓄電器３は複数個を設けることが好ましく、例えば、図１Ａに示したように、複数の急速充電器２のそれぞれに蓄電器３を接続する。一方、充電器３の充電容量が十分に大きい場合には、図１Ｃに示すように、複数の急速充電器２に対して一つの蓄電器３を接続してもよい。 (Condenser)
As the storage battery 3, a lithium ion storage battery, a lead storage battery, a sodium-sulfur storage battery, an all-solid battery, a lithium air battery, a flywheel, or the like can be used.
