〔バッテリ交換システムの構成〕
始めに、図１を参照して、本発明の実施形態となるバッテリ交換システムの構成について説明する。 [Battery replacement system configuration]
First, the configuration of a battery exchange system according to an embodiment of the present invention will be described with reference to FIG.

本発明の実施形態となるバッテリ交換システムは、図１に示すように、車両２，管理センター側に設けられたサーバ２，及びバッテリ交換所側に設けられたサーバ３を主な構成要素として備える。なお本実施形態では、管理センターとバッテリ交換所が別の場所に設けられているとして説明するが、バッテリ交換所内に管理センターがある等して、バッテリ交換所が管理センターの役割を担うようにしてもよい。車両２は、通信装置１１，経路案内装置１２，バッテリ１３，及び制御部１４を備える。通信装置１１は、電気通信回線を介してサーバ２，３との間で情報通信を行う。経路案内装置１２は、公知の経路案内装置により構成され、乗員により設定された目的地までの車両の走行経路を案内する。バッテリ１３は、車両１の駆動源として機能する。   As shown in FIG. 1, the battery exchange system according to the embodiment of the present invention includes a vehicle 2, a server 2 provided on the management center side, and a server 3 provided on the battery exchange side as main components. . In the present embodiment, the management center and the battery exchange are described as being provided at different locations. However, the battery exchange has a role of the management center because the management center is in the battery exchange. May be. The vehicle 2 includes a communication device 11, a route guidance device 12, a battery 13, and a control unit 14. The communication device 11 performs information communication with the servers 2 and 3 via an electric communication line. The route guidance device 12 is configured by a known route guidance device, and guides the traveling route of the vehicle to the destination set by the passenger. The battery 13 functions as a drive source for the vehicle 1.

本実施形態では、バッテリ１３は、図２に示すように、複数の電池モジュール２１を有する組電池により構成され、各電池モジュール２１はさらに複数の電池２２により構成されている。またバッテリ１３は、電池種類（リチウムイオン電池やニッケル水素蓄電池等）、定格容量、各電池モジュール２１のＳＯＣ（State Of Charge），劣化状態，自己放電量、使用履歴、交換履歴、故障部位、及び故障履歴等の情報を記憶，更新するメモリを有する。制御部１４は車両１全体の動作を制御する。サーバ２及びサーバ３はワークステーション等の公知の情報処理装置により構成されている。   In the present embodiment, as shown in FIG. 2, the battery 13 is composed of an assembled battery having a plurality of battery modules 21, and each battery module 21 is further composed of a plurality of batteries 22. The battery 13 includes a battery type (lithium ion battery, nickel metal hydride storage battery, etc.), rated capacity, SOC (State Of Charge) of each battery module 21, deterioration state, self-discharge amount, usage history, replacement history, failure location, and It has a memory for storing and updating information such as failure history. The control unit 14 controls the operation of the entire vehicle 1. The server 2 and the server 3 are configured by a known information processing device such as a workstation.

〔バッテリ交換処理〕
このような構成を有するバッテリ交換システムは、以下に示すバッテリ交換処理を実行することにより、バッテリを安価に交換することを可能にする。以下、図３に示すフローチャートを参照して、このバッテリ交換処理を実行する際のバッテリ交換システムの動作について説明する。 [Battery replacement process]
The battery exchange system having such a configuration enables the battery to be exchanged at low cost by executing the following battery exchange process. Hereinafter, the operation of the battery exchange system when this battery exchange process is executed will be described with reference to the flowchart shown in FIG.

図３に示すフローチャートは、ユーザが経路案内装置１２を操作することによりバッテリの交換要求を入力したタイミングで開始となり、バッテリ交換処理はステップＳ１の処理に進む。   The flowchart shown in FIG. 3 starts at the timing when the user inputs a battery replacement request by operating the route guidance device 12, and the battery replacement process proceeds to step S1.

ステップＳ１の処理では、経路案内装置１２が、車両１の位置情報を検出し、検出された位置情報に基づいて車両１周辺に存在するバッテリ交換所を検索する。これにより、ステップＳ１の処理は完了し、バッテリ交換処理はステップＳ２の処理に進む。   In the process of step S1, the route guidance device 12 detects the position information of the vehicle 1 and searches for a battery exchange located around the vehicle 1 based on the detected position information. Thereby, the process of step S1 is completed and the battery replacement process proceeds to the process of step S2.

ステップＳ２の処理では、制御部１４が、バッテリ１３のメモリと通信することによりバッテリ１３の種類、バッテリ１３を構成する各電池モジュール２１のＳＯＣ，劣化状態，自己放電量、及び故障部位に関する情報を読み出すと共に、経路案内装置１２と通信することによりステップＳ１の処理により検索されたバッテリ交換所への到着予定時刻に関する情報を取得する。また制御部１４は、経路案内装置１２から取得した到着予定時刻に関する情報を利用して、バッテリ交換所に到着した際の各電池モジュール２１のＳＯＣを算出する。これにより、ステップＳ２の処理は完了し、バッテリ交換処理はステップＳ３の処理に進む。   In the process of step S <b> 2, the control unit 14 communicates with the memory of the battery 13 to obtain information on the type of the battery 13, the SOC of each battery module 21 constituting the battery 13, the deterioration state, the self-discharge amount, and the failure part. At the same time as reading, it communicates with the route guidance device 12 to acquire information related to the estimated arrival time at the battery exchange searched in the process of step S1. Further, the control unit 14 calculates the SOC of each battery module 21 when it arrives at the battery exchange using the information about the estimated arrival time acquired from the route guidance device 12. Thereby, the process of step S2 is completed and the battery replacement process proceeds to the process of step S3.

ステップＳ３の処理では、制御部１４が、ステップＳ２の処理により得られた情報を仮予約データとして管理センター側のサーバ２に送信する。なおこの処理において、ユーザが、バッテリ１３の種類や定格容量等のサーバ２に送信する情報を選択できるようにしてもよい。これにより、ステップＳ３の処理は完了し、バッテリ交換処理はステップＳ４の処理に進む。   In the process of step S3, the control unit 14 transmits the information obtained by the process of step S2 to the server 2 on the management center side as temporary reservation data. In this process, the user may be able to select information to be transmitted to the server 2 such as the type and rated capacity of the battery 13. Thereby, the process of step S3 is completed and the battery replacement process proceeds to the process of step S4.

ステップＳ４の処理では、サーバ２が、ステップＳ３の処理により車両１側から送信された仮予約データを受信する。これにより、ステップＳ４の処理は完了し、バッテリ交換処理はステップＳ５の処理に進む。   In the process of step S4, the server 2 receives the provisional reservation data transmitted from the vehicle 1 side by the process of step S3. Thereby, the process of step S4 is completed and the battery replacement process proceeds to the process of step S5.

ステップＳ５の処理では、サーバ２が、仮予約データを参照して交換が必要な電池モジュール２１を特定し、ステップＳ１の処理により目的地に設定されたバッテリ交換所に特定された電池モジュール２１に対応する電池モジュール２１が保管されているか否かを判別する。これにより、ステップＳ５の処理は完了し、バッテリ交換処理はステップＳ６の処理に進む。   In the process of step S5, the server 2 identifies the battery module 21 that needs to be replaced with reference to the provisional reservation data, and the battery module 21 specified in the battery exchange set as the destination by the process of step S1. It is determined whether or not the corresponding battery module 21 is stored. Thereby, the process of step S5 is completed and the battery replacement process proceeds to the process of step S6.

ステップＳ６の処理では、サーバ２が、交換が必要な電池モジュール２１に対応する電池モジュール２１がバッテリ交換所に保管されていない場合、バッテリ交換所の予約状況やその電池モジュール２１を用意するために必要な工数に関する情報をバッテリ交換所側のサーバ２から取得し、交換が必要な電池モジュール２１に対応する交換モジュール２１を用意するために必要な時間及び費用を算出する。なおバッテリ１３を交換する際、バッテリ交換所では、仮予約データを参照して、新たに導入する電池モジュール２１の特性及びＳＯＣを交換が不要な電池モジュール２１の特性及びＳＯＣに合わせる。これにより、電池モジュール２１の交換後にバッテリ１３内で特性ばらつきが発生することを防止できる。これにより、ステップＳ６の処理は完了し、バッテリ交換処理はステップＳ７の処理に進む。   In the process of step S6, when the battery module 21 corresponding to the battery module 21 that needs to be replaced is not stored in the battery exchange place, the server 2 prepares the reservation status of the battery exchange place and the battery module 21. Information on the required man-hours is acquired from the server 2 on the battery exchange station side, and the time and cost necessary for preparing the replacement module 21 corresponding to the battery module 21 that needs to be replaced are calculated. When the battery 13 is replaced, the battery exchange refers to the provisional reservation data and matches the characteristics and SOC of the battery module 21 to be newly introduced to the characteristics and SOC of the battery module 21 that does not require replacement. Thereby, it is possible to prevent the characteristic variation from occurring in the battery 13 after the battery module 21 is replaced. Thereby, the process of step S6 is completed and the battery replacement process proceeds to the process of step S7.

ステップＳ７の処理では、サーバ２が、ステップＳ６の処理により算出された時間及び費用に関する情報を仮予約回答して車両１に送信する。なお交換が必要な電池モジュール２１に対応する電池モジュールが既にバッテリ交換所に保管されている場合には、サーバ２は、交換作業に必要となる時間とその費用に関する情報を仮予約回答として車両１に送信する。また交換する電池モジュール２１の使用履歴や劣化状態に応じて幾つかのランクの交換費用を提示し（図４参照）、ユーザが交換費用を選択できるようにしてもよい。これにより、ステップＳ７の処理は完了し、バッテリ交換処理はステップＳ８の処理に進む。   In the process of step S7, the server 2 responds to the provisional reservation and transmits the information related to the time and expense calculated by the process of step S6 to the vehicle 1. If the battery module corresponding to the battery module 21 that needs to be replaced is already stored in the battery exchange, the server 2 uses the time required for the replacement work and information about the cost as a provisional reservation response for the vehicle 1. Send to. Moreover, according to the use log | history and deterioration state of the battery module 21 to replace | exchange, the replacement expense of several ranks may be shown (refer FIG. 4), and a user may enable it to select replacement expense. Thereby, the process of step S7 is completed and the battery replacement process proceeds to the process of step S8.

ステップＳ８の処理では、車両１の通信装置１１が、サーバ２から送信された仮予約回答を受信し、制御部１４が、経路案内装置１１の表示画面に受信した仮予約回答の内容を出力する。これにより、ステップＳ８の処理は完了し、バッテリ交換処理はステップＳ９の処理に進む。   In the process of step S8, the communication device 11 of the vehicle 1 receives the provisional reservation response transmitted from the server 2, and the control unit 14 outputs the content of the provisional reservation response received on the display screen of the route guidance device 11. . Thereby, the process of step S8 is completed, and the battery replacement process proceeds to the process of step S9.

ステップＳ９の処理では、ユーザがステップＳ８の処理により表示画面に出力された仮予約回答の内容に基づいて仮予約を確定するか否かを判断する。仮予約を確定する場合、ユーザは経路案内装置１２を操作することにより仮予約の確定操作を行い、バッテリ交換処理はステップＳ１０の処理に進む。一方、仮予約を確定しない場合には、ユーザは経路案内装置１２を操作することにより仮予約の解約操作を行い、バッテリ交換処理はステップＳ１の進む。   In the process of step S9, it is determined whether or not the user confirms the temporary reservation based on the content of the temporary reservation answer output on the display screen by the process of step S8. When confirming the provisional reservation, the user operates the route guidance device 12 to perform the provisional reservation confirmation operation, and the battery replacement process proceeds to step S10. On the other hand, when the temporary reservation is not confirmed, the user operates the route guidance device 12 to cancel the temporary reservation, and the battery replacement process proceeds to step S1.

ステップＳ１０の処理では、制御部１１が、通信装置１１を介して予約確定要求を送信し、サーバ２は、予約確定要求を受信したタイミングで制御部１１との間でバッテリ交換費用の決済を行う。そしてバッテリ交換費用の決済が完了したタイミングでサーバ２はバッテリ交換処理をステップＳ１１の処理に進める。   In step S10, the control unit 11 transmits a reservation confirmation request via the communication device 11, and the server 2 settles the battery replacement cost with the control unit 11 at the timing when the reservation confirmation request is received. . Then, the server 2 advances the battery replacement process to the process of step S11 at the timing when the settlement of the battery replacement cost is completed.

ステップＳ１１の処理では、サーバ２が、バッテリ交換所側のサーバ３に対し仮予約データに規定された条件を満足するバッテリの準備（充電や容量調整等）を開始するように指示する。これにより、ステップＳ１１の処理は完了し、一連のバッテリ交換処理は終了する。   In the process of step S11, the server 2 instructs the server 3 on the battery exchange side to start preparation (charging, capacity adjustment, etc.) of a battery that satisfies the conditions defined in the provisional reservation data. Thereby, the process of step S11 is completed and a series of battery exchange processes are complete | finished.

以上の説明から明らかなように、本発明の実施形態となるバッテリ交換処理によれば、車両１が、バッテリ１３の交換要求に応じて電気通信回線を介してバッテリ１３に関する情報を送信し、サーバ２が、送信された情報に基づいてバッテリ１３の交換部位を特定し、特定された交換部位を交換するようにバッテリ交換所のサーバ３に通知する。そしてこのような構成によれば、バッテリ１３を交換する際、バッテリ交換所では交換が必要な部位だけを交換することになるので、バッテリ１３を安価に交換することができる。   As is clear from the above description, according to the battery replacement process according to the embodiment of the present invention, the vehicle 1 transmits information related to the battery 13 via the telecommunication line in response to the replacement request for the battery 13, and the server 2 identifies the exchange site of the battery 13 based on the transmitted information, and notifies the server 3 of the battery exchange site to exchange the identified exchange site. According to such a configuration, when the battery 13 is replaced, only the portion that needs to be replaced is replaced at the battery exchange station, so that the battery 13 can be replaced at low cost.

また本発明の実施形態となるバッテリ交換処理によれば、車両１がサーバ２に送信するバッテリ１３に関する情報は、バッテリ１３の使用履歴、交換履歴、劣化状態、及び故障部位に関する情報を含む。そしてこのような構成によれば、交換が必要なバッテリ１３の部位を適切に特定することができるので、バッテリ１３の整備性が向上する。   Moreover, according to the battery exchange process which becomes embodiment of this invention, the information regarding the battery 13 which the vehicle 1 transmits to the server 2 contains the information regarding the usage history of the battery 13, an exchange history, a deterioration state, and a failure location. And according to such a structure, since the site | part of the battery 13 which needs replacement | exchange can be specified appropriately, the maintainability of the battery 13 improves.

また本発明の実施形態となるバッテリ交換処理によれば、車両１がサーバ２に送信するバッテリ１３に関する情報は、電池モジュール２１の現時点における残存容量とバッテリ交換所に到達した時点における残存容量に関する情報を含むので、バッテリ交換所における容量調整の精度を向上させることができる。 According to the battery exchange process to be embodiments the present invention relates to the remaining capacity at the time the vehicle 1 has reached the remaining capacity and the battery exchange stations at present the information on the battery 13 to be transmitted to the server 2, batteries module 21 Since the information is included, the accuracy of capacity adjustment at the battery exchange can be improved.
