以下、図面を参照して、本発明の実施形態となる充電システム及びその充電動作について説明する。   Hereinafter, a charging system and a charging operation thereof according to an embodiment of the present invention will be described with reference to the drawings.

〔充電システムの構成〕
始めに、図１を参照して、本発明の実施形態となる充電システムの構成について説明する。 [Configuration of charging system]
First, the configuration of a charging 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充電システム１は、図１に示すように、車両２に搭載されたバッテリ（図示せず）を充電する充電器３と、車両２の乗員がバッテリの充電料金を精算するための精算機４と、充電システム１全体の動作を制御するサーバ５とを主な構成要素として備える。なお本実施形態では、精算機４とサーバ５を別体として説明するが、精算機４とサーバ５を一体で構成するようにしてもよい。   As shown in FIG. 1, a charging system 1 according to an embodiment of the present invention includes a charger 3 that charges a battery (not shown) mounted on a vehicle 2, and an occupant of the vehicle 2 settles a battery charging fee. A settlement machine 4 for controlling the operation and a server 5 for controlling the operation of the entire charging system 1 are provided as main components. In the present embodiment, the settlement machine 4 and the server 5 are described as separate bodies. However, the settlement machine 4 and the server 5 may be configured integrally.

車両２は、充電器３から供給される電力を利用してバッテリを充電すると共にバッテリの必要充電量や異常の有無に関する情報を検出する充電部１１と、充電器３及びサーバ５との間で情報通信を行うための通信装置１２と、バッテリの充電動作を制御する制御部１３とを備える。   The vehicle 2 uses the power supplied from the charger 3 to charge the battery and detects the information on the required amount of charge of the battery and the presence / absence of the abnormality between the charger 3 and the server 5. The communication apparatus 12 for performing information communication, and the control part 13 which controls the charging operation of a battery are provided.

充電器３は、車両２の充電部１１に電力を供給する商用電源等の電力供給部２１と、車両２及びサーバ５との間で情報通信を行うための通信装置２２とを備える。本実施形態では、各充電器３には固有の識別情報（固有ＩＤ）が付与されている。   The charger 3 includes a power supply unit 21 such as a commercial power source that supplies power to the charging unit 11 of the vehicle 2, and a communication device 22 for performing information communication between the vehicle 2 and the server 5. In the present embodiment, each charger 3 is given unique identification information (unique ID).

サーバ５は、車両２及び充電器３との間で情報通信を行うための通信装置３１と、車両２，充電器３，及び精算器４の動作を制御することにより充電システム１全体の動作を制御する制御部３２とを備える。   The server 5 controls the operation of the entire charging system 1 by controlling the operation of the communication device 31 for performing information communication between the vehicle 2 and the charger 3, and the vehicle 2, the charger 3, and the settlement device 4. And a control unit 32 for controlling.

〔充電処理〕
このような構成を有する充電システム１は、以下に示す充電処理を実行することにより、バッテリの充電作業の利便性を向上させる。以下、図２に示すフローチャートを参照して、この充電処理を実行する際の充電システム１の動作について説明する。 図３に示すフローチャートは、車両２の乗員が充電部１１に充電器３を接続したタイミングで開始となり、始めに、制御部１３が、通信装置１２を介してサーバ５に対して充電部１１を接続した充電器３の固有ＩＤと共に充電器３が利用可能であるか否かを確認するための照合確認要求を送信する（ステップＳ１）。制御部３２は、車両２から照合確認要求を受信すると、通信装置３１を介して受信した固有ＩＤに対応する充電器３と通信することにより、充電器３が利用可能であるか否かを確認する（ステップＳ２，３）。そして充電器３が利用可能になったタイミングで充電部１１は車両２のバッテリの充電を開始し（ステップＳ４，図５に示す時刻Ｔ＝Ｔ１）、制御部３２は充電料金の課金処理を開始する（ステップＳ５，図５に示す時刻Ｔ＝Ｔ１）。なお故障等の原因によって充電器３が利用不能である場合、制御部３２は、車両２や充電器３に対し充電を行うことができない旨の情報を送信し、車両２や充電器３は車両２の乗員に対し充電を行うことができない旨を報知する。 [Charging process]
The charging system 1 having such a configuration improves the convenience of the battery charging operation by executing the following charging process. Hereinafter, the operation of the charging system 1 when this charging process is executed will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 3 starts when the occupant of the vehicle 2 connects the charger 3 to the charging unit 11. First, the control unit 13 connects the charging unit 11 to the server 5 via the communication device 12. A verification confirmation request for confirming whether or not the charger 3 is usable is transmitted together with the unique ID of the connected charger 3 (step S1). When the control unit 32 receives the verification confirmation request from the vehicle 2, the control unit 32 confirms whether or not the charger 3 can be used by communicating with the charger 3 corresponding to the unique ID received via the communication device 31. (Steps S2, 3). Then, at the timing when the charger 3 becomes available, the charging unit 11 starts charging the battery of the vehicle 2 (step S4, time T = T1 shown in FIG. 5), and the control unit 32 starts the charging fee charging process. (Step S5, time T = T1 shown in FIG. 5). In addition, when the charger 3 cannot be used due to a failure or the like, the control unit 32 transmits information indicating that the vehicle 2 or the charger 3 cannot be charged. Inform the passenger 2 that charging cannot be performed.

バッテリの充電が行われている間、充電部１１はバッテリの充電異常がないか否かを確認する（ステップＳ６）。そして充電異常が生じた場合、充電部１１はバッテリの充電を停止し、制御部１３は通信装置１２を介してバッテリの充電異常をサーバ５に通知する（ステップＳ７）。以後、制御部３２は、運転者が充電料金を精算する際、精算機４を介してバッテリの充電異常を運転者に通知すると共に充電異常が生じるまでの充電料金を課金するように精算機４を制御する。一方、充電異常が生じなかった場合には、制御部３２は、運転者が精算器４を操作することにより充電料金の精算を指示したタイミング（図５に示す時刻Ｔ＝Ｔ２）で、精算器４から充電器３（又は車両２）までの距離を充電器３（又は駐車位置）毎に示すテーブルを参照して、精算器４からステップＳ１の処理において受信した固有ＩＤに対応する充電器３までの距離を算出する（ステップＳ８，Ｓ９）。精算器４から車両２までの距離が算出されると、制御部３２は、図３（ａ），（ｂ），（ｃ）に示すテーブル及び以下の数式１を用いて、運転者が精算器４から車両２に移動するまでの間にバッテリを充電可能な時間を追加充電可能時間として算出する（ステップＳ１０）。

Figure 0005321087
While the battery is being charged, the charging unit 11 checks whether or not there is a battery charging abnormality (step S6). When charging abnormality occurs, the charging unit 11 stops charging the battery, and the control unit 13 notifies the server 5 of charging abnormality of the battery via the communication device 12 (step S7). Thereafter, when the driver settles the charging fee, the control unit 32 notifies the driver of the battery charging abnormality via the settlement machine 4 and charges the charging fee until the charging abnormality occurs. To control. On the other hand, when the charging abnormality does not occur, the control unit 32 controls the settlement unit at the timing when the driver instructs settlement of the charging fee by operating the settlement unit 4 (time T = T2 shown in FIG. 5). 4 with reference to a table showing the distance from charger 4 to charger 3 (or vehicle 2) for each charger 3 (or parking position). Is calculated (steps S8 and S9). When the distance from the settlement machine 4 to the vehicle 2 is calculated, the control unit 32 uses the tables shown in FIGS. 3A, 3B, and 3C and the following formula 1 to set the driver to the settlement machine. The time during which the battery can be charged before moving from 4 to the vehicle 2 is calculated as the additional chargeable time (step S10).
Figure 0005321087

具体的には、制御部３２は、ステップＳ９の処理により算出された精算器４から充電器３までの距離を所定の歩行速度（例えば８０ｍ／分）で除算した値に車両２を駐車したフロアまでのエレベータによる移動時間を加算する。エレベータによる移動時間は、例えば２階に駐車した場合には１０秒等、図３（ａ）に示すような各駐車フロア毎の移動時間を記述したテーブルを参照することにより算出される。そしてサーバ５の制御部３２は、算出された値に天候係数及び荷物量係数を乗算することにより追加充電可能時間を算出する。   Specifically, the control unit 32 is a floor on which the vehicle 2 is parked at a value obtained by dividing the distance from the settlement machine 4 to the charger 3 calculated by the process of step S9 by a predetermined walking speed (for example, 80 m / min). Add the travel time by the elevator up to. The travel time by the elevator is calculated by referring to a table describing the travel time for each parking floor as shown in FIG. 3A, for example, 10 seconds when parking on the second floor. Then, the control unit 32 of the server 5 calculates the additional chargeable time by multiplying the calculated value by the weather coefficient and the luggage amount coefficient.

本実施形態において、荷物量係数とは、乗員の移動時間に対する乗員の荷物量の影響を示す係数であり、乗員の荷物量がカーゴが必要になるほど多い場合には乗員の移動は困難になると予測されるので、乗員の荷物量が多い時の荷物量係数は図３（ｂ）に示すように荷物が少ない場合（カーゴ不要の場合）と比べて移動時間が長く算出されるように１以上の値に設定されている。また天候係数とは、乗員の移動時間に対する天候の影響を示す係数であり、天候が雨の場合には乗員の移動は困難になると予測されるので、天候が雨の時の天候係数は図３（ｃ）に示すように雨以外の天気と比べて移動時間が長く算出されるように１以上の値に設定されている。なお乗員の荷物量は、例えばカメラにより撮影された乗員の画像を解析することにより判断することができ、天候は雨滴センサを配置することにより判断することができる。   In this embodiment, the luggage amount coefficient is a coefficient indicating the influence of the passenger's luggage amount on the traveling time of the passenger, and it is predicted that the movement of the passenger will be difficult when the passenger's luggage amount is large enough to require cargo. As shown in FIG. 3 (b), the load amount coefficient when the occupant's load is large is 1 or more so that the travel time is calculated longer than when the load is small (when no cargo is required). Is set to a value. The weather coefficient is a coefficient indicating the influence of the weather on the travel time of the occupant, and it is predicted that the occupant will be difficult to move when the weather is rainy. As shown in (c), the value is set to 1 or more so that the travel time is calculated longer than the weather other than rain. The passenger's luggage amount can be determined, for example, by analyzing an image of the passenger photographed by a camera, and the weather can be determined by arranging a raindrop sensor.

より具体的には、図４に示すように乗員が雨の日に車両２を立体駐車場の３階に駐車し、精算器４と車両２（充電器３）との間の直線距離が１２０ｍ（８０ｍ＋４０ｍ）ｍと算出された場合、制御部３２は、乗員の荷物量が少ない場合には以下の数式２に示すように追加充電可能時間を１６５秒と算出する。なお以下の数式２では、乗員の歩行速度は８０ｍ／分に設定されている。

Figure 0005321087
More specifically, as shown in FIG. 4, the occupant parks the vehicle 2 on the third floor of the multilevel parking lot on a rainy day, and the linear distance between the settlement machine 4 and the vehicle 2 (charger 3) is 120 m. When (80m + 40m) m is calculated, the control unit 32 calculates the additional chargeable time as 165 seconds as shown in the following Expression 2 when the passenger's load is small. In the following formula 2, the occupant's walking speed is set to 80 m / min.
Figure 0005321087

このようにして追加充電可能時間が算出されると、制御部３２は、車両２の制御部１３から必要充電量に関する情報を受信し、受信した情報とステップＳ１０の処理により算出された追加充電可能時間に基づいて、追加充電可能時間通りバッテリを充電可能であるか否かを判別する（ステップＳ１１）。そして判別の結果、追加充電可能時間だけ充電してもバッテリの充電量が必要充電量以上の値にならず、追加充電可能時間通りバッテリを充電可能である場合、制御部３２は、追加充電可能時間だけバッテリを充電するように車両２及び充電器３を制御する（ステップＳ１３）。一方、追加充電可能時間前にバッテリの充電量が満充電状態又は必要充電量になる等して追加充電可能時間通りバッテリを充電できない場合には、制御部３２は、可能な充電量だけ充電するように車両２及び充電器３を制御する（ステップＳ１２）。   When the additional chargeable time is calculated in this way, the control unit 32 receives information on the necessary charge amount from the control unit 13 of the vehicle 2 and can perform additional charge calculated by the received information and the process of step S10. Based on the time, it is determined whether or not the battery can be charged according to the additional chargeable time (step S11). As a result of the determination, if the amount of charge of the battery does not exceed the required charge amount even if charging is performed for the additional chargeable time and the battery can be charged according to the additional chargeable time, the control unit 32 can perform additional charge. The vehicle 2 and the charger 3 are controlled so as to charge the battery for the time (step S13). On the other hand, when the amount of charge of the battery reaches the full charge state or the necessary charge amount before the additional chargeable time, and the battery cannot be charged according to the additional chargeable time, the control unit 32 charges as much as possible. Thus, the vehicle 2 and the charger 3 are controlled (step S12).

以上のようにして追加充電処理が開始されると、制御部３２は、精算器４を介して追加充電処理の充電料金を今回支払うか否かを運転者に確認する（ステップＳ１４）。そして確認の結果、追加充電処理の充電料金を今回支払わないと運転者が指示した場合、制御部３２は、現在までの充電料金を課金，請求する（ステップＳ１５）。但し、現段階で未納の充電料金がある場合には、制御部３２は、現在までの充電料金に合わせて未納の充電料金を課金，請求する。一方、追加充電処理の充電料金を今回支払うと運転者が指示した場合には、制御部３２は、現在までの充電料金と合わせて追加充電処理の充電料金を課金，請求する（ステップＳ１６）。充電料金の精算が完了すると、制御部３２は追加充電処理の完了後に充電を停止するように車両２及び充電器３を制御する（ステップＳ１７，Ｓ１８，図５に示す時刻Ｔ＝Ｔ３）。なお図５に示すように、充電処理は乗員が車両に戻る時刻Ｔ＝Ｔ４よりも前の時刻Ｔ＝Ｔ３に終了させることが望ましい。   When the additional charging process is started as described above, the control unit 32 confirms with the driver whether or not to pay the charging fee for the additional charging process this time via the settlement machine 4 (step S14). As a result of the confirmation, when the driver instructs that the charging fee for the additional charging process is not paid this time, the control unit 32 charges and charges the current charging fee (step S15). However, if there is an unpaid charge at the current stage, the control unit 32 charges and bills an unpaid charge according to the current charge. On the other hand, when the driver instructs to pay the charging fee for the additional charging process this time, the control unit 32 charges and charges the charging fee for the additional charging process together with the current charging fee (step S16). When the settlement of the charging fee is completed, the control unit 32 controls the vehicle 2 and the charger 3 so as to stop the charging after the completion of the additional charging process (steps S17 and S18, time T = T3 shown in FIG. 5). As shown in FIG. 5, it is desirable that the charging process be terminated at time T = T3 prior to time T = T4 when the occupant returns to the vehicle.

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充電処理によれば、サーバ５は、バッテリの充電料金の精算要求が入力されたタイミングで車両２又は充電器３と精算機５との間の距離を算出し、算出された距離に基づいて車両２の乗員が精算機５から車両２に移動するまでの時間を追加充電可能時間として算出し、算出された追加充電可能時間だけバッテリを充電するように充電器３を制御する。そしてこのような構成によれば、車両２の乗員は空き時間の間に少量でもバッテリを充電できるので、バッテリの充電作業の利便性が向上する。   As is clear from the above description, according to the charging process according to the embodiment of the present invention, the server 5 is configured such that the vehicle 2 or the charger 3 and the payment machine 5 The time until the passenger of the vehicle 2 moves from the settlement machine 5 to the vehicle 2 is calculated as the additional chargeable time based on the calculated distance, and the battery is calculated for the calculated additional chargeable time. The charger 3 is controlled so as to be charged. And according to such a structure, since the passenger | crew of the vehicle 2 can charge a battery even if it is a little during idle time, the convenience of the charge operation of a battery improves.

また本発明の実施形態となる充電処理によれば、サーバ５は、天候と乗員の歩行速度及び荷物量を考慮して追加充電可能時間を算出するので、追加充電可能時間を正確に算出し、少量でもより多くバッテリを充電することができる。また本発明の実施形態となる充電処理によれば、乗員が精算機４から車両２に移動するまでの間にバッテリの充電量が所定値に到達するか否かを判別し、充電量が所定値に到達する場合、バッテリの充電量が所定値に到達するまでの時間を追加充電可能時間として算出するので、適切な課金設定を行うことができる。   Further, according to the charging process according to the embodiment of the present invention, the server 5 calculates the additional chargeable time in consideration of the weather, the walking speed of the occupant, and the amount of luggage, so the additional chargeable time is accurately calculated, Even a small amount can charge the battery more. Further, according to the charging process according to the embodiment of the present invention, it is determined whether or not the battery charge amount reaches a predetermined value before the occupant moves from the checkout machine 4 to the vehicle 2, and the charge amount is predetermined. When the value reaches the value, the time until the amount of charge of the battery reaches the predetermined value is calculated as the additional chargeable time, so that an appropriate charging setting can be performed.

以上、本発明者らによってなされた発明を適用した実施の形態について説明したが、この実施形態による本発明の開示の一部をなす記述及び図面により本発明は限定されることはない。このように本実施形態に基づいて当業者等によりなされる他の実施の形態、実施例及び運用技術等は全て本発明の範疇に含まれる。   As mentioned above, although embodiment which applied the invention made by the present inventors was described, this invention is not limited by description and drawing which make a part of indication of this invention by this embodiment. As described above, other embodiments, examples, operation techniques, and the like made by those skilled in the art based on the present embodiment are all included in the scope of the present invention.
