Description

本発明は、特に、車両に蓄電池を搭載し、地上に設置された充電設備から電力の供給を受け、軌道上や路面等の設定された経路を走行する架線レス交通システムの充電システム及び充電方法に関する。   The present invention particularly relates to a charging system and a charging method for an overhead wire-less traffic system in which a storage battery is mounted on a vehicle, receives power from a charging facility installed on the ground, and travels on a set route such as on a track or on a road surface. About.

近年、車両が軌道上や路面等の設定された経路を走行する新交通システムにおいて、架線から電力の供給を受けずに走行する電動車両を用いた架線レス交通システムが提案されている。そのため、かかる電動車両には、蓄電池が搭載されている。
このような架線レス交通システムは、例えば、特許文献１（特開２００５−２６９６８７号公報）に開示されている。 In recent years, in a new traffic system in which a vehicle travels on a set route such as on a track or on a road surface, an overhead wire-less traffic system using an electric vehicle that travels without receiving power from the overhead wire has been proposed. Therefore, a storage battery is mounted on such an electric vehicle.
Such an overhead line-less traffic system is disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-269687.

上記特許文献１に開示された車両用非接触充電装置は、図５に示すように、外部電源に接続される１次コイル５３を、車両５１の動力用バッテリ５２に接続される２次コイル５４に電磁結合させ、動力用バッテリ５２を充電する非接触式の充電装置であり、１次コイル５３を、車両５１が走行する路面Rと略同一面で、かつ車両５１が走行しない位置に設置するとともに、当該１次コイル５３を、車両５１の床底面５１ａに設けられた２次コイル５４の下方に迫り出すように、構成されている。   As shown in FIG. 5, the non-contact charging device for a vehicle disclosed in Patent Document 1 includes a primary coil 53 connected to an external power source and a secondary coil 54 connected to a power battery 52 of the vehicle 51. Is a non-contact type charging device for charging the power battery 52, and the primary coil 53 is installed on a position substantially flush with the road surface R on which the vehicle 51 travels and where the vehicle 51 does not travel. At the same time, the primary coil 53 is configured to protrude below the secondary coil 54 provided on the floor bottom surface 51 a of the vehicle 51.

なお、図５に示すように、２次コイル５４には、整流器５５と、ＲＢＣＩ（リモートバッテリチャージインターフェース）５６と、赤外線通信送受信器５７とが直列に接続されており、ＲＢＣＩ５６には、ＢＭＳ（バッテリマネージメントシステム）５８が接続されている。一方、非接触式充電用高周波電源装置６１は、充電スタンド６２側に設置されている。この電源装置６１には、ＣＰＵ６３が設けられており、該ＣＰＵ６３の指令によって充電スタンド６２側の赤外線通信送受信器６４と車両５１側の赤外線通信送受信器５７との間で高周波信号の授受を行うとともに、制御装置６５によってアクチュエータ６６、すなわち１次コイル５３の送り出し用モータ及び昇降用モータを制御するようになっている。また、図５中のＣ１及びＣ２は、それぞれリレーの接点である。   As shown in FIG. 5, a rectifier 55, an RBCI (Remote Battery Charge Interface) 56, and an infrared communication transmitter / receiver 57 are connected in series to the secondary coil 54, and the RBCI 56 has a BMS ( A battery management system) 58 is connected. On the other hand, the non-contact charging high-frequency power supply device 61 is installed on the charging stand 62 side. The power supply device 61 is provided with a CPU 63, and receives and transmits a high frequency signal between the infrared communication transmitter / receiver 64 on the charging stand 62 side and the infrared communication transmitter / receiver 57 on the vehicle 51 side according to an instruction from the CPU 63. The control device 65 controls the actuator 66, that is, the motor for raising and lowering the primary coil 53. Further, C1 and C2 in FIG. 5 are relay contacts, respectively.

特開２００５−２６９６８７号公報JP 2005-269687 A

しかしながら、図５に示されるような従来の車両用非接触充電装置にあっては、１次コイル５３を２次コイル５４側に迫り出すための送り出し機構、及び２次コイル５４に対して接近又は離反させるための昇降機構が設けられているので、１次コイル５３の駆動機構が複雑となり、コスト高を招く上に、該駆動機構の動作時間が長いという問題点を有している。例えば、ゴムタイヤ式の新交通システムであるＡＰＭ（Ａｕｔｏｍａｔｅｄ Ｐｅｏｐｌｅ Ｍｏｖｅｒ）では、数十秒の駅停車中に急速充電をする必要があるが、駆動機構の動作時間が数秒掛かると、その分充電時間が削られることになり、十分に充電することができないおそれがある。   However, in the conventional non-contact charging device for a vehicle as shown in FIG. 5, the feeding mechanism for pushing the primary coil 53 toward the secondary coil 54 and the secondary coil 54 are approached or approached. Since the elevating mechanism for separating is provided, the drive mechanism of the primary coil 53 becomes complicated, resulting in high costs and a long operating time of the drive mechanism. For example, APM (Automated People Mover), which is a new rubber tire type transportation system, needs to be charged quickly while the station is stopped for several tens of seconds. There is a possibility that the battery will be scraped and cannot be fully charged.

また、従来の充電装置の１次コイル５３及び２次コイル５４は、寸法が大きく、水平方向に配置されているので、幅狭な箇所に収容することができず、設置箇所が制限されてしまうという問題点を有している。しかも、上記１次コイル５３及び２次コイル５４では、非接触電力伝送の原理から両コイルのギャップを大きく設定することができないので（例えば、数十〜２００ｍｍ程度のギャップ）、車両５１が荷重変化などに基づいて上下動すると、両コイルが接触してしまうおそれがある。   Moreover, since the primary coil 53 and the secondary coil 54 of the conventional charging device are large in size and arranged in the horizontal direction, they cannot be accommodated in a narrow location, and the installation location is limited. Has the problem. Moreover, in the primary coil 53 and the secondary coil 54, the gap between the two coils cannot be set large due to the principle of non-contact power transmission (for example, a gap of about several tens to 200 mm). When moving up and down based on the above, both coils may come into contact with each other.

本発明は、このような実状に鑑みてなされたものであって、その目的は、大きな寸法の送電装置及び受電装置を使用し、かつ送電装置の駆動機構を無くしたり、あるいは簡素化することによって、十分な充電時間を確保することが可能となり、車両の上下動による送電装置と受電装置との接触を避け、地上側の送電装置を周辺機器と干渉させることなく設置するとともに、車両側の受電装置をデッドスペースなどを有効に利用して設置することが可能な充電システム及び充電方法を提供することにある。   The present invention has been made in view of such a situation, and an object of the present invention is to use a power transmission device and a power reception device having large dimensions and to eliminate or simplify a drive mechanism of the power transmission device. It is possible to secure a sufficient charging time, avoid contact between the power transmission device and the power reception device due to vertical movement of the vehicle, install the ground side power transmission device without interfering with peripheral devices, and receive power on the vehicle side. An object of the present invention is to provide a charging system and a charging method capable of installing a device by effectively using a dead space.

上記従来技術の有する課題を解決するために、本発明は、蓄電池を搭載した車両が、地上に設置された充電設備から電力の供給を受け、予め設定された経路を走行する交通システムの充電システムにおいて、前記充電設備には複数の送電装置が設けられ、該送電装置は、駅構内のプラットホームの前後位置に配置され、かつ走行路面側に臨む側面に縦置きに固定して設けられているとともに、前記車両の車輪よりも前方位置及び後方位置のそれぞれにおいて、受電装置が前記車両の車体側面の下部より下方へ向かって縦置きに固定して設けられ、前記送電装置と前記受電装置とを互いに対向させて配置することにより、前記蓄電池の充電が行われるように構成されている。 In order to solve the above-described problems of the prior art, the present invention provides a charging system for a traffic system in which a vehicle equipped with a storage battery receives power supplied from a charging facility installed on the ground and travels on a preset route. in the the charging facility provided with a plurality of power transmitting device, the sending device, provided with fixed vertically on a side surface disposed before and after the position of the station yard of the platform, and faces the traveling road surface Rutotomoni The power receiving device is fixed in a vertically-positioned manner downward from the lower part of the side surface of the vehicle body of the vehicle at each of a front position and a rear position with respect to the wheel of the vehicle, and the power transmitting device and the power receiving device are connected to each other. by disposed opposite charge of the storage battery is configured to divide the line.

さらに、本発明の充電システムにおいては、車両が荷重変動などに基づいて上下動した場合でも、送電装置と受電装置とが接触するということは起こらないので、車両の荷重変化やタイヤパンクなどを想定して送電装置と受電装置との間のギャップ寸法を設定する必要がなくなる上、送電装置及び受電装置の損傷を防止できる。しかも、地上側の送電装置を信号線やガイド機構などの周辺機器と干渉させることなく設置することが可能となり、レイアウトの自由度を向上させることができる。 As described above, the charging system according to the present invention is applied to a transportation system in which a vehicle equipped with a storage battery is supplied with electric power from a charging facility installed on the ground and travels on a preset route. a plurality of power transmission device is provided in, the sending device is placed before and after the position of the station yard platform and provided fixed to the upright on the side facing the road surface side Rutotomoni, the wheels of the vehicle In each of the front position and the rear position, the power receiving device is vertically fixed from the lower part of the side surface of the vehicle body of the vehicle, and the power transmitting device and the power receiving device are arranged to face each other. by, the charging of the storage battery is configured to divide the line, it is possible to use a power transmitting device and a power receiving device of large dimensions, perform rapid charging in a short time Door can be.

図1で示される車両１は、架線レスの軌道系交通システムに適用されるものであり、車体下部の前後左右の４箇所に車輪としてのゴムタイヤ２を備え、予め設定された軌道経路の走行路面２０を電力で走行する電動車両である。このため、車両１には、ゴムタイヤ２を駆動する図外の駆動モータと、該駆動モータに駆動電流を送る蓄電池（例えば、リチウムイオン２次電池）３と、駆動モータを制御する図外のコントローラと、車載受電装置（２次コイル）４とが設けられており、該受電装置４において発生した起電力は、図外の整流器で直流に変換され、蓄電池３に蓄電されるようになっている。 [First embodiment]
FIG. 1 is a schematic front view of a charging system according to a first embodiment of the present invention applied to an overhead line-less traffic system.
A vehicle 1 shown in FIG. 1 is applied to a track-based transportation system without an overhead wire, and includes rubber tires 2 as wheels at four locations on the front, rear, left, and right of the lower part of a vehicle body, and a traveling road surface of a predetermined track route. 20 is an electric vehicle that travels with electric power. For this reason, the vehicle 1 includes a drive motor (not shown) that drives the rubber tire 2, a storage battery (for example, a lithium ion secondary battery) 3 that sends a drive current to the drive motor, and a controller (not shown) that controls the drive motor. And an in-vehicle power receiving device (secondary coil) 4, and an electromotive force generated in the power receiving device 4 is converted into direct current by a rectifier (not shown) and stored in the storage battery 3. .

また、車両１には、該車両の走行、その他車両全体の制御を行う車載制御装置５と、後述の地上通信装置と赤外線等を用いて通信することにより地上側と情報交換を行う車載通信装置６と、当該車両の位置を検知する図外の位置センサとが搭載されており、この位置センサで走行中の車両１の位置が検知されると、車載制御装置５によって車両１が所定の位置で停止されるような制御が行われるように構成されている。   In addition, the vehicle 1 includes a vehicle-mounted control device 5 that controls the travel of the vehicle and other vehicles, and a vehicle-mounted communication device that exchanges information with the ground side by communicating with a ground communication device described later using infrared rays or the like. 6 and a position sensor (not shown) for detecting the position of the vehicle. When the position of the traveling vehicle 1 is detected by the position sensor, the vehicle-mounted control device 5 moves the vehicle 1 to a predetermined position. It is configured to perform control such that it is stopped at.

本発明の第1実施形態に係る車載受電装置４は、後述のプラットホーム側に対面する車両１の前後部片側側面にそれぞれ固定して設けられている。すなわち、受電装置４は、図示しないコアと巻き線とを用いて構成され、側面視で円形や四角形等の板状に形成されており、ゴムタイヤ２よりも前方位置及び後方位置のそれぞれにおいて、車両１の車体側面の下部より下方へ向かって縦置きにして設けられている。このような受電装置４の縦置きの配置は、車両１の前後部における比較的大きな空きスペースの利用を図り、受電装置４の上下寸法や前後寸法の長さＬを従来に比べて大きく形成（例えば、９００ｍｍ以上）することを可能ならしめるものである。   The in-vehicle power receiving device 4 according to the first embodiment of the present invention is fixedly provided on one side surface of the front and rear portions of the vehicle 1 facing the platform side described later. That is, the power receiving device 4 is configured by using a core and a winding (not shown), and is formed in a plate shape such as a circle or a quadrangle in a side view. 1 is provided vertically from the lower part of the side surface of the vehicle body. Such a vertical arrangement of the power receiving device 4 makes it possible to use a relatively large empty space in the front and rear portions of the vehicle 1, and the length L of the vertical size and the front and rear dimensions of the power receiving device 4 are made larger than before ( (For example, 900 mm or more).

一方、地上の充電場所である駅構内には、地上充電設備１０が設置されている。この地上充電設備１０には、充電電源１１と、地上充電制御装置１２と、車載通信装置６との情報交換を行う地上通信装置１３と、複数（本実施形態では２個）の地上送電装置（１次コイル）１４とが設けられている。
本実施形態の地上送電装置１４は、車載受電装置４と略同一の構成、形状及び大きさを有しており、駅構内のプラットホーム１５の前後位置に配置され、かつ走行路面２０側に臨む側面に縦置きに固定して設けられている。そして、車両１が駅構内の所定位置に停車した場合には、車載受電装置４と地上送電装置１４とが一定のギャップ（空隙）を空けて対峙されるように構成されている。なお、地上送電装置１４と充電電源１１とは、スイッチ１６を介して給電線１７により接続されている。そして、プラットホーム１５上の走行路面２０側には、ホームドア１８が設置されている。 On the other hand, a ground charging facility 10 is installed in a station yard which is a ground charging place. The ground charging facility 10 includes a charging power source 11, a ground charging control device 12, a ground communication device 13 for exchanging information with the in-vehicle communication device 6, and a plurality (two in this embodiment) of ground power transmission devices ( Primary coil) 14 is provided.
The ground power transmission device 14 of the present embodiment has substantially the same configuration, shape, and size as the in-vehicle power receiving device 4, is disposed at the front and rear positions of the platform 15 in the station premises, and is a side surface facing the traveling road surface 20 side. Are fixed vertically. When the vehicle 1 stops at a predetermined position in the station, the in-vehicle power receiving device 4 and the ground power transmitting device 14 are confronted with a certain gap (gap).

Along with this, a high-frequency electromagnetic field is generated in the ground power transmission device 14, the electromagnetic field of the ground power transmission device 14 is received by electromagnetic induction in the in-vehicle power receiving device 4, and an induced electromotive force is generated in the in-vehicle power receiving device 4, AC current flows. The generated electromotive force is converted into DC power by a rectifier (not shown), transmitted to the storage battery 3 and stored, whereby charging is performed.
Then, after the start of charging, in the on-vehicle charging control device (not shown), the charging voltage of the storage battery 3 is compared with a preset value of the charging end voltage, and the voltage of the storage battery 3 reaches the setting voltage, or a predetermined charging time When the time elapses, a charging end command is transmitted to the ground charging control device 12 via the in-vehicle communication device 6, and energization of the vehicle 1 by the charging power source 11 is stopped. Next, a vehicle start permission command is transmitted from the ground charge control device 12 to the vehicle-mounted control device 5 via the vehicle-mounted charge control device (not shown), and the vehicle-mounted control device 5 starts the vehicle 1.

また、本実施形態の充電システムによれば、地上送電装置１４が固定式であり、駆動機構が不要となるため、システムの簡素化によるコストダウンを図ることができるとともに、充電時の操作時間を短縮でき、充電時間を長く取ることができる。
さらに、本実施形態の充電システムによれば、車両１が荷重変動などに基づいて上下動した場合でも、地上送電装置１４と車載受電装置４とが一定のギャップを保ち、接触するということは起こらないため、車両１の荷重変化などを想定して地上送電装置１４と車載受電装置４との間のギャップ寸法を設定する煩雑な作業が不要となり、かつ地上送電装置１４及び車載受電装置４の損傷を防止し、耐久性を向上させることができる。しかも、地上送電装置１４を信号線２３やガイド機構２１，２２と干渉させることなく容易に設置でき、レイアウトの自由度を高めることができる。 Moreover, according to the charging system of this embodiment, since the ground power transmission apparatus 14 is a fixed type and a drive mechanism becomes unnecessary, it is possible to reduce the cost by simplifying the system and reduce the operation time during charging. It can be shortened and a long charging time can be taken.
Furthermore, according to the charging system of the present embodiment, even when the vehicle 1 moves up and down based on a load variation or the like, the ground power transmission device 14 and the in-vehicle power receiving device 4 maintain a certain gap and come into contact with each other. Therefore, the complicated work of setting the gap dimension between the ground power transmission device 14 and the in-vehicle power receiving device 4 assuming the load change of the vehicle 1 is not required, and the ground power transmitting device 14 and the in-vehicle power receiving device 4 are damaged. Can be prevented and durability can be improved. Moreover, the ground power transmission device 14 can be easily installed without interfering with the signal line 23 and the guide mechanisms 21 and 22, and the degree of layout freedom can be increased.
