- the installation plan storage unit 101 and the traffic model storage unit 102 are implemented by an external storage device.
- the installation plan storage unit 101 holds, for example, a place and number of candidates for installing the charger in the real world.
- the charger cannot be installed anywhere, but it is assumed that it will be installed in an existing gas station, shopping center, parking lot, etc. Therefore, the location where the charger can be installed and the number of installable devices are stored in the installation plan storage unit 101 in advance.
- the location where the charger is installed is stored in a format that allows the position on the road data stored in the traffic model storage unit 102, such as coordinates on the map, latitude and longitude, to be specified.
- Information on the installation location and number of chargers is transmitted to the simulation unit 103, and is used by the simulation unit 103 to determine the location and number of installations of the virtual charger.
- the traffic model storage unit 102 stores information on the road network in the real world and a vehicle movement model on the road network. Or you may make it memorize
- the road network information stored in the traffic model storage unit 102 is represented by, for example, a node corresponding to an intersection and a link corresponding to a road connecting the intersections as shown in FIG. For each link, distance, the number of lanes, a speed limit, and the like are set as parameters representing road characteristics. These parameters affect the travel time of the vehicle and the road congestion.
- the vehicle movement model stored in the traffic model storage unit 102 is represented by an OD (Origin-Destination) table, for example, as shown in FIG.
- the OD table shows the number of vehicles moving from the start zone to the end zone.
- a zone includes several nodes as shown in FIG.
- the simulation unit 103 simulates the traffic simulation unit 1031 that simulates the movement of a plurality of virtual electric vehicles and the consumption of a rechargeable battery on a virtual road network that reproduces a road in the real world, and the use situation of a virtual charger.
- the charger simulation unit 1032 is provided.

Further, the starting node, departure time, etc. of each virtual vehicle are appropriately determined based on the population distribution of the starting zone, traffic survey data, and the like. For example, if data is obtained that the number of vehicles that depart from zone i from 8:00 to 9:00 is 20% of the total number of vehicles starting from zone i, 8 data from zone i to zone j are obtained. : 00 to 9: virtual vehicle departs in 00 to 0.2t ij table.
- each virtual vehicle moves while consuming a rechargeable battery. Therefore, when the remaining charge of the rechargeable battery decreases during the movement, the charger determination unit 104 determines which charger to charge and moves to the installation location of the charger. For this reason, the traffic simulation unit 1031 transmits parameters related to the virtual vehicle such as the position of each virtual vehicle, the remaining charge of the rechargeable battery, and the end point zone to the charger determination unit 104 during the simulation.
- the charger simulation unit 1032 simulates the usage status of the virtual charger arranged on the virtual road network, and transmits the status to the charger determination unit 104.
- Each virtual charger becomes “in use” when a virtual vehicle with a low charge remaining in the rechargeable battery comes and starts charging, and other virtual vehicles cannot be used until charging is completed. Therefore, while a certain virtual charger is “in use”, the virtual vehicle that comes later waits for the charging order on the spot.
- the state of the virtual charger returns to “available”.
- the charger simulation unit 1032 notifies the charger determination unit 104 of a change in the state (“in use”, “available”) of the virtual charger. Note that the time required to complete charging of one virtual vehicle, the charging speed, and the like are appropriately set in accordance with the characteristics of each virtual charger.

- the charger determination unit 104 determines a virtual charger to be selected according to the usage status of the virtual charger and the state of the virtual vehicle. For example, if the virtual charger on the route to the end point zone is “in use” and cannot be used, another available virtual charger is searched and selected so that the route does not change significantly. Further, even if the remaining charge of a rechargeable battery of a certain virtual vehicle is still sufficient, it may be determined to charge if there is an empty virtual charger on the route. Further, when the virtual charger on the route is “in use” and cannot be used, the nearest virtual charger may be selected by going back a little on the path that has passed. As described above, the charger determination unit 104 selects the virtual charger so that the waiting time for charging each virtual vehicle and the movement time to the end point zone are as short as possible.
- the simulation unit 103 outputs the movement history of each virtual vehicle and the operation history of each virtual charger as simulation results when all the virtual vehicles arrive at the end point and the simulation is completed.

- the traffic simulation unit 1031 outputs a route traveled by each virtual vehicle, a travel distance, a charging place, the number of times of power shortage, a position where power is lost, and the like as the movement history of the virtual vehicle. Using this data, for example, if the position where each virtual vehicle has a shortage of electricity is displayed on a map, it can be used to examine where the charger should be installed or added in the real world.
- the charger simulation unit 1032 outputs, as the operation history of the virtual charger, a history of the usage status of the virtual charger being simulated, a waiting time until each virtual vehicle is charged, and the like. Using this data, for example, if you calculate the average operating rate of each virtual charger, consider removing virtual chargers with low operating rates from the installation plan, or close to virtual chargers with high operating rates. Or consider adding a charger.

The amount is transmitted to the charger determination unit 104 (S201).
- Whether or not the virtual vehicle needs to be charged may be determined based on the remaining charge of the rechargeable battery, for example, when the remaining charge becomes 30% or less of the total capacity. Further, the traffic simulation unit 1031 may transmit information on all virtual vehicles to the charger determination unit 104 without determining whether or not each virtual vehicle needs to be charged. In this case, the charger determination unit 104 determines whether or not each virtual vehicle needs to be charged.

- the solid line is the shortest route to the destination of the virtual vehicle at point O.
- a charger A at a point P there are a charger B at a point Q, and a charger C at a point S as candidates for a virtual charger that can be reached with the current remaining charge.
- the charger determination unit 104 performs calculation as shown in FIG. 6 for each virtual vehicle, and determines a virtual charger to be used.
- the charger determination unit 104 can select a virtual charger having a minimum reachable time. Thereby, the virtual charger closest to the virtual vehicle can be selected. In the example of FIG. 6, the charger C is selected.
- the charger determination unit 104 may select a virtual charger with a minimum extra moving distance. As a result, the total travel distance until the arrival at the destination can be shortened, so that the overall energy consumption can be minimized. In the example of FIG. 6, the charger A is selected.
- the same virtual charger may be selected for a plurality of virtual vehicles. In this case, it may be determined to which virtual vehicle the virtual charger is assigned based on other criteria. For example, for the virtual vehicle E and the virtual vehicle F, when the virtual charger G is selected with the shortest reachable time, the virtual charger G is assigned to the virtual vehicle with the shorter extra travel distance, and the other For the virtual vehicle, a virtual charger with the next shortest reachable time is selected. By repeating the above processing, it is possible to cope with the case where the selected virtual chargers overlap.
- the traffic simulation unit 1031 moves the corresponding virtual vehicle to the position of the virtual charger used by each based on the information of the virtual charger acquired in step S203 (step S204).

図1は、本発明の実施の形態1による充電器配置計画支援装置10の構成を示すブロック図である。図に示すように、充電器配置計画支援装置10は、設置計画案記憶部101、交通モデル記憶部102、シミュレーション部103、充電器決定部104を備えている。シミュレーション部103は、交通シミュレーション部1031および充電器シミュレーション部1032を備えている。
交通モデル記憶部102が記憶する道路網の情報は、例えば図2に示すように、交差点に対応するノードと、交差点間をつなぐ道路に対応するリンクで表されている。各リンクには道路の特徴を表すパラメータとして、距離、車線数、制限速度などが設定されている。これらのパラメータは、車両の移動時間や道路の混み具合に影響を与える。
図4は、本実施の形態の充電器配置計画支援装置10の動作例を示すフローチャートである。なお、後述の各処理ステップは、処理内容に矛盾を生じない範囲で、任意に順番を変更して又は並列に実行することができるとともに、各処理ステップ間に他のステップを追加してもよい。また、便宜上1ステップとして記載されているステップは、複数ステップに分けて実行することができる。また、便宜上複数ステップに分けて記載されているものは、1ステップとして把握することができる。
図に示すように、交通シミュレーション部1031は、各仮想車両の位置と充電池の電荷残量の情報を収集し、充電が必要と判断した仮想車両の位置、目的地(終点ゾーン)、電荷残量を充電器決定部104に送信する(S201)。
まず、充電器決定部104は、各仮想車両について、図6に示すような、現在の電荷残量で到達可能な仮想充電器の情報を算出する。算出するのは、各仮想充電器に到達するまでに要する余分な移動距離と、仮想充電器への到達に要する予想時間(到達可能時間)である。なお、余分な移動距離とは、目的地(終点ゾーン)へ移動するために、最短ルートと比較して余分に走行しなければならない距離である。
図10は、本発明の実施の形態2による充電器配置計画支援装置20の構成を示すブロック図である。図10に示すように、実施の形態2による充電器配置計画支援装置20は、実施の形態1による充電器配置計画支援装置10の構成に加えて、設置計画策定部205を備えている。その他の構成については実施の形態1と同様である。実施の形態1と同様の構成要素については、図1と同一の符号を付している。
