Description

本発明は、電気自動車の充電システムに関するものである。   The present invention relates to a charging system for an electric vehicle.

電気自動車を充電する際に電気自動車側に保持された情報を取得する電気自動車の充電システムとしては、特許文献１に記載のものが知られている。この従来例において、充電ケーブルを電気自動車に接続すると、電気自動車に蓄積された充電履歴データが室内コントローラ（充電装置）側に伝達され、充電装置側で走行可能距離、充電完了率等を表示する。
特開平９-２３３７２０号公報 As a charging system for an electric vehicle that acquires information held on the electric vehicle side when charging the electric vehicle, the one described in Patent Document 1 is known. In this conventional example, when the charging cable is connected to the electric vehicle, the charging history data accumulated in the electric vehicle is transmitted to the indoor controller (charging device) side, and the charging device side displays the travelable distance, the charging completion rate, and the like. .
JP-A-9-233720

しかし、上述した従来例において、充電装置は充電状態等を表示するにとどまり、車両の状態により充電が調整されることはないために、例えば、走行に適しない車両に対しても充電がなされてしまうという問題がある。   However, in the above-described conventional example, the charging device only displays the charging state and the like, and charging is not adjusted depending on the state of the vehicle. For example, charging is performed even for a vehicle that is not suitable for traveling. There is a problem of end.

一方、電気自動車の走行には充電操作、すなわち、充電装置への電気的、あるいは電磁的接続が必須であるために、車両情報の取得はガソリンエンジンを搭載した車両に比して大幅に容易になり、この点を利用することにより、未整備車両、未点検車両の走行を制限することが可能になる。   On the other hand, since a charging operation, that is, an electrical or electromagnetic connection to a charging device is indispensable for running an electric vehicle, it is much easier to obtain vehicle information than a vehicle equipped with a gasoline engine. Thus, by using this point, it is possible to limit the travel of unmaintained vehicles and uninspected vehicles.

本発明は、以上の欠点を解消すべくなされたものであって、車両の整備、点検状態によって車両への充電量を制限することにより、走行不的確車両の走行を制限することのできる電気自動車の充電システムの提供を目的とする。   The present invention has been made to solve the above-described drawbacks, and an electric vehicle capable of restricting the travel of a vehicle inaccurately by restricting the amount of charge to the vehicle depending on the state of maintenance and inspection of the vehicle. The purpose is to provide a charging system.

本発明によれば上記目的は、
予め設定された車両点検項目に対する評価値を外部出力可能な電気自動車１と、
電気自動車１に充電する充電装置２とを有し、
前記充電装置２には、電気自動車１と交信して車両点検項目に対する評価値を取得し、当該評価値に基づいて予め設定された基準によりフル充電量からの減量値を演算する減量値演算部３と、
減量値演算部３における減量値を差し引いた充電量に達した際に充電を停止する充電量制限部４と、
を有する電気自動車の充電システムを提供することにより達成される。 According to the present invention, the object is
An electric vehicle 1 capable of outputting an evaluation value for a preset vehicle inspection item externally;
A charging device 2 for charging the electric vehicle 1;
The charging device 2 communicates with the electric vehicle 1 to obtain an evaluation value for a vehicle inspection item, and calculates a reduction value from the full charge amount based on a preset criterion based on the evaluation value. 3 and
A charge amount limiting unit 4 that stops charging when the charge amount obtained by subtracting the weight loss value in the weight loss value calculating unit 3 is reached;
It is achieved by providing a charging system for an electric vehicle having

充電システムにおける電気自動車１は、車両モニタシステムにより予め定められた車両点検項目に関する評価値を取得することが可能であり、取得した評価値は、無線、電力線通信等、適宜の通信手段により充電装置２に伝送される。評価値情報は、ブレーキ系等、安全運転に支障を来すような部位に配置したセンサの出力を検出することにより得られ、センサのタイプにより、ＯＫ、ＮＧの２値情報、あるいは状態表示信号、さらには計測値であってもよい。   The electric vehicle 1 in the charging system can acquire an evaluation value relating to a vehicle inspection item predetermined by the vehicle monitoring system, and the acquired evaluation value is charged by a suitable communication means such as wireless or power line communication. 2 is transmitted. The evaluation value information is obtained by detecting the output of a sensor arranged at a location that interferes with safe driving, such as a brake system. Depending on the type of sensor, binary information of OK, NG, or status display signal Further, it may be a measured value.

充電装置２の充電量制限部４は、各項目に対して予め設定された重み付けにより制限比率を演算し、充電量を本来のフル充電量に比して少ない量に設定し、当該充電量に達すると充電を終了する。   The charge amount restriction unit 4 of the charging device 2 calculates a restriction ratio by weighting set in advance for each item, sets the charge amount to a small amount compared to the original full charge amount, and sets the charge amount to the charge amount. When it reaches, charging is terminated.

したがってこの発明において、車両点検項目に重大な欠陥がある場合等には、充電量を、例えば整備工場まで走行するために必要な量に制限したり、あるいは比較的軽微な欠陥がある場合には修理を促すために充電量を制限することによって、要修理車両の運行を規制することができる。   Therefore, in the present invention, when there is a serious defect in the vehicle inspection item, the amount of charge is limited to the amount necessary for traveling to a maintenance shop, for example, or when there is a relatively minor defect By restricting the amount of charge in order to prompt repair, the operation of the vehicle requiring repair can be restricted.

また、充電システムは、電気自動車１に履歴格納部５を搭載して構成することができる。すなわち、
前記電気自動車１は、前記充電量制限部４における充電制限を受けた履歴を格納する履歴格納部５を備え、
前記充電量制限部４は、前記履歴格納部５内の履歴により充電制限量を変化させる充電システムを構成すると、車両運行者に必要な点検、修理を強く促すことができる。 The charging system can be configured by mounting the history storage unit 5 in the electric vehicle 1. That is,
The electric vehicle 1 includes a history storage unit 5 that stores a history of charge restriction in the charge amount restriction unit 4.
If the charge amount limiting unit 4 constitutes a charging system that changes the charge limit amount based on the history in the history storage unit 5, the vehicle operator can be urged to perform necessary inspections and repairs.

要点検箇所が存在する場合の警報は、車両点検項目を検知する車両側で行うことができるが、充電装置２側に表示部６を設けると、車両に比して表示部６を大きくすることができるために、より詳細に状況を利用者に知らせることができる。   The alarm when there is a point requiring inspection can be issued on the vehicle side that detects the vehicle inspection item, but if the display unit 6 is provided on the charging device 2 side, the display unit 6 is made larger than the vehicle. To be able to inform the user of the situation in more detail.

また、表示部６を室内に配置し、充電状況を併せて表示すると、室内で充電終了等を知ることができ、利便性が向上する。   Further, when the display unit 6 is arranged indoors and the charging status is also displayed, it is possible to know the end of charging in the room and the convenience is improved.

本発明によれば、車両の整備、点検状態によって車両への充電量を制限することができるために、走行不的確車両の公道での走行を制限し、交通事故を減少させることができる。   According to the present invention, since the amount of charge to the vehicle can be limited depending on the maintenance and inspection state of the vehicle, it is possible to limit the traveling of the uncertain vehicle on the public road and reduce traffic accidents.

図１に本発明の実施の形態を示す。まず、充電システムに使用される電気自動車１は、接続部１ａを経由して充電装置２からの給電を受けて充電されるバッテリ７と、ＡＤ変換器等を含む充電回路８と、接続部１ａへの充電ケーブル９の接続を検出するための接続検出部１ｂとを有する。   FIG. 1 shows an embodiment of the present invention. First, an electric vehicle 1 used in a charging system includes a battery 7 that is charged by receiving power from a charging device 2 via a connecting portion 1a, a charging circuit 8 including an AD converter, and a connecting portion 1a. And a connection detector 1b for detecting the connection of the charging cable 9 to the.

また、電気自動車１には、制御部１０の制御によって動作する電力線通信部１１、車両モニタシステム１２、および履歴格納部５が設けられる。電力線通信部１１は、充電ケーブル９の電力線を通信線として利用して充電装置２との交信を行い、充電装置２に車両モニタシステム１２による取得データを送信する。   In addition, the electric vehicle 1 is provided with a power line communication unit 11, a vehicle monitor system 12, and a history storage unit 5 that operate under the control of the control unit 10. The power line communication unit 11 communicates with the charging device 2 using the power line of the charging cable 9 as a communication line, and transmits the acquired data from the vehicle monitoring system 12 to the charging device 2.

車両モニタシステム１２は、車載コンピュータに自己診断プログラムを搭載することにより実現され、充電動作時、あるいは始動時等のタイミングで起動されて該当センサの出力を検出する。この実施の形態において、車両モニタシステム１２によるモニタリングのために、ウォッシャ液残量センサ１２ａ、タイヤ空気圧センサ１２ｂ、ランプ切れセンサ１２ｃ、ブレーキ系異常検出センサ１２ｄ、サスペンション系異常検出センサ１２ｅ、操舵系異常検出センサ１２ｆが搭載される。   The vehicle monitor system 12 is realized by mounting a self-diagnosis program on an in-vehicle computer, and is activated at a timing such as a charging operation or a start-up to detect the output of the corresponding sensor. In this embodiment, for monitoring by the vehicle monitoring system 12, a washer fluid remaining amount sensor 12a, a tire air pressure sensor 12b, a lamp burnout sensor 12c, a brake system abnormality detection sensor 12d, a suspension system abnormality detection sensor 12e, a steering system abnormality A detection sensor 12f is mounted.

また、履歴格納部５には、後述する充電装置２における給電制限を受けた場合、その履歴が格納される。   Further, the history storage unit 5 stores the history when the power supply restriction in the charging device 2 described later is received.

一方、この実施の形態において充電装置２は、カーポート等の近傍に設置され、充電ケーブル９を接続するためのコンセント等の接続部２ａと、接続部２ａへの充電ケーブル９の接続を検出するための接続検出部２ｂと、商用電源入力部１３から接続部２ａへの給電の開始、停止を制御するための給電制御部１４とを有する。   On the other hand, in this embodiment, charging device 2 is installed in the vicinity of a car port or the like, and detects connection portion 2a such as an outlet for connecting charging cable 9, and connection of charging cable 9 to connecting portion 2a. A connection detection unit 2b, and a power supply control unit 14 for controlling the start and stop of power supply from the commercial power supply input unit 13 to the connection unit 2a.

また、充電装置２には、制御部１５に制御されて動作する減量値演算部３、充電量制限部４、車両情報記憶部１６、表示部６、および操作スイッチ１７が配置される。車両情報記憶部１６は、電力線通信部１１、１８を経由して電気自動車１側から送信される車両モニタシステムにより取得された各センサの出力値（評価値）を格納し、必要に応じて表示部６に表示する。操作スイッチ１７は、表示部６における表示内容の変更等に使用される。   Further, the charging device 2 is provided with a decrease value calculation unit 3, a charge amount restriction unit 4, a vehicle information storage unit 16, a display unit 6, and an operation switch 17 that are controlled by the control unit 15. The vehicle information storage unit 16 stores the output value (evaluation value) of each sensor acquired by the vehicle monitor system transmitted from the electric vehicle 1 via the power line communication units 11 and 18, and displays it as necessary. Displayed in part 6. The operation switch 17 is used for changing display contents on the display unit 6.

減量値演算部３は、車両点検項目の評価値から減量値を演算する。減量値演算部３における演算は、上記各評価値を項目の重篤度に応じて重み付けをした他の評価値と比較可能なランク値として再評価し、この後、これらの合計値により車両全体として整備不良状況を評価することにより行われる。減量値はこのようにして演算された整備不良指数により決定され、例えばパーセント値として定義される。この結果、整備不良指数の高いもの、すなわち、重篤な整備不良項目を含む場合等には、例えば、６０％、あるいは７０％等の大きな値が設定される。   The weight loss value calculation unit 3 calculates the weight loss value from the evaluation value of the vehicle inspection item. The calculation in the weight loss value calculation unit 3 re-evaluates each evaluation value as a rank value that can be compared with other evaluation values weighted according to the severity of the item, and thereafter, the total vehicle value is calculated based on these total values. This is done by evaluating the poor maintenance situation. The weight loss value is determined by the maintenance failure index calculated in this way, and is defined as, for example, a percentage value. As a result, when the maintenance defect index is high, that is, when serious maintenance failure items are included, a large value such as 60% or 70% is set.

これらランク値の再評価、整備不良指数の減量値への換算等は、実験等により予め決定され、演算テーブル３ａに格納される。   The re-evaluation of the rank value, the conversion of the maintenance failure index into the reduced value, etc. are determined in advance by experiments or the like and stored in the calculation table 3a.

また、この実施の形態において、減量値演算部３は、減量値の演算に際し、電気自動車１側の履歴格納部５に充電制限履歴を問い合わせ、この結果により整備不良指数を増減させる。これにより、同一の車両点検項目に対する不具合が連続して示された場合、整備不良指数を高めることによって整備を促すことが可能になる。充電制限履歴の利用は、例えば、軽微な項目に対しては、複数回の指摘があって、かつ整備がなされない場合にのみランク値を与える等、柔軟に設定することができる。   Further, in this embodiment, the weight reduction value calculation unit 3 inquires the charge storage history to the history storage unit 5 on the electric vehicle 1 side when calculating the weight reduction value, and increases or decreases the maintenance failure index based on the result. As a result, when troubles with respect to the same vehicle inspection item are continuously indicated, maintenance can be promoted by increasing the maintenance failure index. The use of the charge restriction history can be set flexibly, for example, for a minor item, a rank value is given only when there are multiple indications and maintenance is not performed.

充電量制限部４は、バッテリ性能上のフル充電量に上記減量値演算部３からの整備状況指数を掛け合わせた量を新たなフル充電量として充電量を監視し、上記設定されたフル充電量に達すると、給電制御部１４に充電停止信号を出力して充電動作を停止させる。   The charge amount limiting unit 4 monitors the charge amount by setting the amount obtained by multiplying the full charge amount on the battery performance by the maintenance status index from the reduction value calculation unit 3 as a new full charge amount, and the set full charge When the amount is reached, a charging stop signal is output to the power supply control unit 14 to stop the charging operation.

充電量の監視は、充電開始時に電気自動車１側の充電回路にフル充電までの充電時間、あるいは充電電力を問い合わせ、これを基準とすることができる。また、電気自動車１側での充電量等の把握が困難な場合、充電時間で充電量を規制したり、あるいは充電電流の単位時間あたりの減少値により規制することができる。   The charge amount can be monitored by inquiring about the charge time until full charge or the charge power to the charging circuit on the electric vehicle 1 side at the start of charging, and using this as a reference. When it is difficult to grasp the amount of charge on the electric vehicle 1 side, the amount of charge can be regulated by the charging time, or can be regulated by a decrease value of the charging current per unit time.

車両情報記憶部１６は、上記減量値演算部３において重篤な充電制限が加えられた際の充電日時、制限理由等が格納される。この車両情報記憶部１６内の情報は適宜手段で後日取り出すことが可能であり、例えば、事故等が発生した場合の車両の整備状況を示す証明等として使用できる。   The vehicle information storage unit 16 stores a charging date and time, a reason for limitation, and the like when a serious charge limitation is applied in the weight loss value calculation unit 3. The information in the vehicle information storage unit 16 can be taken out later by appropriate means, and can be used, for example, as proof indicating the maintenance status of the vehicle when an accident or the like occurs.

さらに、表示部６は、上記充電量制限がある場合にその旨を表示し、車両の整備を促すとともに、充電時間、現在の充電量等を表示する。   Further, the display unit 6 displays the fact that there is a restriction on the charge amount, prompts maintenance of the vehicle, and displays the charge time, the current charge amount, and the like.

この表示部６を室内に配置すると、室内で充電状況を知ることができるために、利便性が向上する。   When the display unit 6 is arranged indoors, the charging state can be known indoors, and convenience is improved.

図２に以上のように構成される充電システムの電気自動車１側の動作フローを示す。まず、メカニカルスイッチにより形成される接続検出部１ｂが充電ケーブル８の接続を検出すると（ステップ１００）、車両モニタシステム１２により収集した各車両点検項目の評価値を電力線通信部１１を経由して充電装置２に送出し（ステップ１０１）、この後、充電回路８を起動してＡＤ変換等の充電処理が開始される（ステップ１０２）。   FIG. 2 shows an operation flow on the electric vehicle 1 side of the charging system configured as described above. First, when the connection detection unit 1b formed by the mechanical switch detects the connection of the charging cable 8 (step 100), the evaluation values of the vehicle inspection items collected by the vehicle monitoring system 12 are charged via the power line communication unit 11. Then, the charging circuit 8 is activated to start charging processing such as AD conversion (step 102).

充電が開始されると充電回路８は、例えば充電電流等を監視することにより充電終了を監視する。充電終了は、充電完了フラグを立てることにより判別され、制御部１０は、充電処理を開始した後、充電完了フラグが立っているか否かを判定する（ステップ１０３）。   When charging is started, the charging circuit 8 monitors the end of charging by monitoring the charging current, for example. The end of charging is determined by setting a charging completion flag, and the control unit 10 determines whether or not the charging completion flag is set after starting the charging process (step 103).

ステップ１０３で充電完了状態でない場合、充電が完了したか否かが検出され（ステップ１０４）、充電完了が検出された場合、充電処理が終了する（ステップ１０５）。充電処理が終了すると、充電完了フラグを立てて充電完了状態にセットし（ステップ１０６）、次いで、充電状態、すなわち充電完了した旨を充電装置２に出力する（ステップ１０７）。   If the charging is not completed in step 103, it is detected whether or not the charging is completed (step 104). If the charging is detected, the charging process ends (step 105). When the charging process is completed, the charging completion flag is set and set to the charging completion state (step 106), and then the charging state, that is, the charging completion is output to the charging device 2 (step 107).

充電状態の送出ステップ（ステップ１０７）は、ステップ１０３で充電完了フラグが検出された場合、およびステップ１０４で充電が完了していない場合にも実行され、ステップ１０７による場合には充電完了状態が、ステップ１０８による場合には、充電中状態が送出される。   The charging state sending step (step 107) is also executed when the charging completion flag is detected at step 103 and when charging is not completed at step 104. In step 107, the charging completion state is In the case of step 108, the charging state is sent out.

ステップ１０７が実行された後、接続部１ａからの充電ケーブル９の離脱を待って（ステップ１０８）充電処理を終了する（ステップ１０９）。   After step 107 is executed, the charging process is terminated (step 109) after the charging cable 9 is disconnected from the connecting portion 1a (step 108).

これに対し、ステップ１００で接続が検出されなかった場合、すなわち、ステップ１０９による充電終了を経た場合には、履歴情報が更新されたか否か、すなわち、新たに整備不良箇所等を理由とする充電量制限が加えられたか否かを充電装置２に問い合わせ（ステップ１１０）、更新された場合、履歴格納部５に記憶する（ステップ１１１）。   On the other hand, if the connection is not detected in step 100, that is, if the charging is completed in step 109, whether or not the history information has been updated, that is, charging is newly performed due to a poorly maintained location or the like. The charging device 2 is inquired as to whether or not the amount limit has been added (step 110), and if updated, the history storage unit 5 stores it (step 111).

図３に充電装置２の制御フローを示す。まず、接続検出部２ｂの出力から接続部２ａへの充電ケーブル９の接続が検出されると（ステップ２００）、車両側からの車両情報を受信したか否かを判定し（ステップ２０１）、受信時には車両情報記憶部１６に格納する（ステップ２０２）。   FIG. 3 shows a control flow of the charging device 2. First, when the connection of the charging cable 9 from the output of the connection detection unit 2b to the connection unit 2a is detected (step 200), it is determined whether or not vehicle information from the vehicle side has been received (step 201). Sometimes it is stored in the vehicle information storage unit 16 (step 202).

ステップ２０１で車両情報の受信を確認できない場合、接続部２ａにおける充電ケーブル９の接続解除を判定し（ステップ２１０）、接続解除を検出できない場合にはステップ２０１に復帰し、接続解除が検出された場合、初期ルーチンに復帰する。   If the reception of vehicle information cannot be confirmed in step 201, it is determined whether or not the charging cable 9 is disconnected in the connecting portion 2a (step 210). If the connection release cannot be detected, the process returns to step 201, and the connection release is detected. Return to the initial routine.

この後、車両情報表示を表示部６に表示し（ステップ２０３）、さらに、減量値演算部３による演算結果に基づいて充電量を設定し（ステップ２０４）、充電用電源からの給電を開始する（ステップ２０５）。   Thereafter, the vehicle information display is displayed on the display unit 6 (step 203), and further, the charge amount is set based on the calculation result by the reduction value calculation unit 3 (step 204), and the power supply from the charging power source is started. (Step 205).

充電は、車両側から出力される充電状態情報と、充電量制限部４における設定値により管理され、充電状態を受信すると（ステップ２０６）、充電量が設定値に達したか否かを判定する（ステップ２０７）。ステップ２０６、２０７は充電量が所定値に達するまで実行され、設定値に達すると給電を停止し（ステップ２０８）、接続部２ａでの接続の解除を監視する（ステップ２０９）。   Charging is managed by the charge state information output from the vehicle side and the set value in the charge amount limiting unit 4. When the charge state is received (step 206), it is determined whether or not the charge amount has reached the set value. (Step 207). Steps 206 and 207 are executed until the amount of charge reaches a predetermined value. When the amount reaches the set value, the power supply is stopped (step 208), and the disconnection at the connection unit 2a is monitored (step 209).

これに対し、ステップ２０６で充電状態を受信しなかった場合、充電終了を確認するために、接続部２ａにおける接続解除を検出する（ステップ２１０）。ステップ２１０で解除が検出された場合には給電を停止して初期ルーチンに復帰し（ステップ２１１）、接続解除が検出されなかった場合、ステップ２０６に復帰する。   On the other hand, when the charging state is not received in step 206, the connection release at the connecting portion 2a is detected in order to confirm the end of charging (step 210). If release is detected in step 210, the power supply is stopped and the process returns to the initial routine (step 211). If connection release is not detected, the process returns to step 206.
