  The data center 140 can acquire weather, temperature, traffic information on main roads, and the like via the Internet. The obtained weather, temperature, traffic jam information, etc. are stored in the database 142.

  The details of the power supply procedure in the power supply system 100 will be described below with reference to FIG. In addition, transmission / reception of various data, information, signals, etc. among the stores 110A to 110C, the delivery vehicles 120A to 120C, the collection / delivery center 130, and the data center 140 is actually performed by the communication units 117, 126, described above. In the following description, it will be described by the expression “the stores 110A to 110C, the delivery vehicles 120A to 120C, the collection and delivery center 130, and the data center 140 transmit and receive”.

  First, as shown in step S100 of FIG. 3, each of the stores 110A to 110C stores the data on the amount of generated power in the past predetermined period before the current time obtained by monitoring of the charge monitoring unit 113 and the charge control unit 114, The power amount data and the power consumption amount data are transmitted to the data center 140.

  In step S110, the data center 140 uses the power amount data output from the stores 110A to 110C, and uses the data of the power amounts output from the stores 110A to 110C. Calculate (predict) the predicted power consumption. Here, the data center 140 determines the predetermined period based on the delivery cycle. For example, if the delivery cycle in which the delivery vehicles 120A to 120C move through the stores 110A to 110C is half a day, the same period can be set as the predetermined period.

  When calculating the predicted amount of generated power and the predicted amount of stored power, the weather (irradiation amount), temperature, humidity, wind power from the present time to the specified period based on the generated power amount data and stored power amount data at the same time as the past respectively. Etc., taking account of the above. In addition, when estimating the power consumption prediction amount, the calculation is performed based on the power consumption data at the same time as the past, taking into account the presence / absence of a special event in a predetermined period from the present time. The generated power amount data, the stored power amount data, and the consumed power amount data at the same time as the past correspond to the actual generated power amount, the actual stored power amount, and the actual consumed power amount in the present invention, respectively. That is, the data center 140 calculates each power predicted amount based on each past power actual amount.

Then, the data center 140 calculates (predicts) the amount of power that can be supplied in each of the stores 110A to 110C based on the power balance of the predicted power consumption with respect to the predicted generated power and the predicted stored power. here,
When the power balance of each store = (predicted power generation amount + predicted power storage amount) −predicted power consumption amount, the power amount when the power balance is positive (surplus) is the suppliable power amount. A store having a positive power balance is a store that can supply power to the delivery vehicles 120A to 120C. The store which can be supplied corresponds to the building for supply in the present invention. Hereinafter, the store that can be supplied is referred to as a store 110 that can be supplied for convenience.

  At this time, the collection / distribution center 130 transmits information on the planned original operation route to each of the delivery vehicles 120A to 120C and the data center 140 in step S120.

  In addition, each delivery vehicle 120A to 120C transmits to the collection / delivery center 130 data on the amount of electric power stored in the vehicle in a past predetermined period before the present time obtained by monitoring by the charge monitoring unit 123 in step S130. Then, the collection / delivery center 130 transmits the data on the amount of electric power stored in the vehicle received from each of the delivery vehicles 120 </ b> A to 120 </ b> C to the data center 140.

  In step S140, the data center 140 calculates (predicts) the required vehicle electric energy in each of the delivery vehicles 120A to 120C. The amount of electric power required for the vehicle is obtained by subtracting the current electric energy stored in the vehicle from the predicted electric energy that is expected to be used in the vehicle storage battery 122 for the delivery vehicles 120A to 120C to go around the stores 110A to 110C. (Insufficient power). For example, the data center 140 calculates the vehicle power requirement as follows.

  (A) That is, the data center 140 operates the travel distance to the supplyable store 110, the estimated travel time, the traffic jam information, the outside air temperature, the weight of the luggage, and the amount of heat required to keep the luggage cool (actuate the electric compressor). The required power amount is calculated by estimating the predicted power amount using at least one condition of the power required for the power source.

  (B) Alternatively, the data center 140 uses the actual power consumption values of the delivery vehicles 120A to 120C in the past predetermined period, and further considers the weather, travel day, travel time, outside air temperature, etc. Calculate the amount.

  The weather and outside air temperature are estimated from data obtained from the Internet, vehicle probe data (wiper, outside air temperature data) and season / time data.

  Then, in step S150, the data center 140, based on the data on the suppliable power amount in the suppliable store 110, the operation route information transmitted from the collection / distribution center 130, and the data on the required vehicle electric energy calculated above. Develop a power supply plan. The power supply plan is based on which route (corresponding to the operation route for supply in the present invention), which power supply plan, which store (corresponding to the supply building in the present invention) and how much power. This is a plan in which contents such as whether to supply an amount (corresponding to the amount of supplied power in the present invention) should be decided.

  For example, when the data center 140 circulates the stores 110 </ b> A to 110 </ b> C among the delivery vehicles 120 </ b> A to 120 </ b> C, the store 110 that can supply power to the delivery vehicle that is predicted to be insufficient with the current vehicle power storage power. The power supply plan is created so that the power is reliably supplied from the vehicle and the route traveled by the delivery vehicle is the shortest. Hereinafter, of the delivery vehicles 120 </ b> A to 120 </ b> C, a delivery vehicle that is predicted to be insufficient with the current vehicle stored power is referred to as a power-deficient vehicle 120 for convenience. The power shortage vehicle 120 corresponds to a target delivery vehicle that is a target of power supply in the present invention.

In setting the route,
(1) In consideration of the power supply at the store where the power shortage vehicle 120 stays, a supply operation route is calculated for each power shortage vehicle 120. The supply operation route is newly determined based on the initial operation route, for example, as a route that goes around in order from the store closest to the power-deficient vehicle 120 among the stores 110 that can be supplied.

(2) The priority is determined from the most important power shortage vehicle 120 among the above (1). The power shortage vehicle 120 with high importance is, for example, a delivery vehicle having the longest travel distance for delivery or a power shortage vehicle 120 having the highest luggage cost per travel distance. Or the power shortage vehicle 120 with high importance is the power shortage vehicle 120 in which the improvement degree of the cleanness degree with respect to the environment becomes the highest by the power supply. For example, in a cold car, the passenger car and the truck have a larger amount of CO ₂ emission due to exhaust from the engine than the passenger car. Therefore, when an idle stop is performed when the vehicle is stopped and the electric compressor is operated with the electric power of the vehicle storage battery 122, the cleanliness of the truck with respect to the environment is improved compared to the passenger car.

  (3) If there is a power-deficient vehicle 120 whose power supply overlaps with respect to the power-deficient vehicle 120 already determined in the process of (2), another route candidate is searched.

  (4) Repeat (2) and (3) above.

  In setting the operation route for supply, when the data center 140 supplies power from the supplyable store 110 to the power-deficient vehicle 120, when there are a plurality of supplyable stores 110, among the plurality of supplyable stores 110, Power is supplied to the power-deficient vehicle 120 from the closest available supply store 110, or power is supplied sequentially from the plurality of supplyable stores 110 while the power-deficient vehicle 120 goes around the plurality of supplyable stores 110. can do. In addition, when power is supplied sequentially from a plurality of stores 110 that can be supplied, the power supply amount per time is limited so that power can be supplied to as many power-deficient vehicles 120 as possible from one store 110 that can be supplied. can do. For example, the power supply amount may be the minimum power amount required for the power-deficient vehicle 120 to move from the staying store to the next supplyable store 110. Note that the timing of power supply is the time at which the power-deficient vehicle 120 is expected to arrive at the first supplyable store 110.

  The data center 140 transmits the power supply plan information created above to the stores 110 </ b> A to 110 </ b> C and the collection / delivery center 130. The collection / distribution center 130 transmits the received power supply plan information to the delivery vehicles 120A to 120C. That is, the data center 140 issues a command for supplying power to the stores 110A to 110C and the delivery vehicles 120A to 120C.

  Among the delivery vehicles 120A to 120C, when the power shortage vehicle 120 receives the power supply plan information, the original operation route is changed to the supply operation route and moves between the stores 110A to 110C.

  When the power-deficient vehicle 120 arrives at the store 110 that can be supplied, the vehicle storage battery 122 and the store storage battery 112 are electrically connected by the driver (occupant) in step S160. Then, a charge request signal is output from the vehicle storage battery 122 side to the store storage battery 112 side.

  In step S170, charging is accepted at the supply available store 110. Furthermore, in step S180, charging from the store storage battery 112 to the vehicle storage battery 122 (DC-DC charging) is performed. In step S190, when the charge amount reaches the planned charge amount, the charging is terminated.

  As described above, in the present embodiment, the data center 140 has a surplus in the power balance of the predicted amount of power consumption with respect to the predicted amount of generated power and the predicted amount of stored power in each of the stores 110A to 110C. The suppliable electric energy that can be supplied to the delivery vehicles 120A to 120C is predicted. Then, based on the available power amount, the operation route of the delivery vehicles 120 </ b> A to 120 </ b> C, and the vehicle stored power amount of the vehicle storage battery 122, the power shortage vehicle 120 and the power shortage vehicle 120 to be supplied with power An electric power supply plan that determines the supply available store 110 for supplying electric power, an operation route for supply for supplying electric power, and the amount of electric power supplied from the supply available store 110 to the electric power shortage vehicle 120 is designed. Yes. Further, based on the power supply plan, a command for executing power supply from the supplyable store 110 to the power shortage vehicle 120 is issued to the stores 110A to 110C and the delivery vehicles 120A to 120C. .

  Thereby, surplus supplyable electric power in the stores 110 </ b> A to 110 </ b> C can be supplied to the power shortage vehicle 120, and the power obtained by the solar power generation device 111 can be effectively used for the power shortage vehicle 120. Can do.

  The data center 140 also sets the power supply amount to be supplied from the first supplyable store 110 when the two or more supplyable stores 110 are set when preparing the power supply plan. The minimum amount of electric power required to move to the supplyable store 110 that receives the electric power supply is set as the minimum electric power.

  As a result, it is possible to suppress the amount of power supplied to one power-deficient vehicle 120, so that it is possible to supply power to a large number of power-deficient vehicles 120 from one available store 110. In addition, the power shortage vehicle 120 does not receive a large amount of power supply at a time, but receives a minimum amount of power supply in order among the stores 110 that can supply it, so the vehicle storage battery 122 needs to be excessively large. Therefore, it is possible to reduce the weight and cost of the power-deficient vehicle 120, and thus the delivery vehicles 120A to 120C.

  In addition, when the data center 140 makes a power supply plan, the data center 140 determines the amount of power supplied based on the travel distance, travel time, traffic congestion information on the supply operation route, outside air temperature, baggage, and the like. Is determined based on a predicted power amount predicted to be used by the power-deficient vehicle 120 based on at least one of the weight and the heat amount required for keeping the luggage cold.

  This makes it possible to estimate the predicted power amount in accordance with the actual driving conditions of the power-deficient vehicle 120, and to accurately determine the supplied power amount from this predicted power amount.

  In addition, when the data center 140 makes a power supply plan, it is also possible to determine the amount of power supplied based on the actual amount of power used at the time of delivery of the power-deficient vehicle 120 in the past predetermined period.

  In this case, it is possible to predict the required power amount in accordance with the past actual power consumption amount of the power-deficient vehicle 120, and the supplied power amount can be accurately determined from the required power amount.

  In addition, when the power supply plan is made, the data center 140 preferentially determines the supply operation route from the supply available stores 110 closest to the power-deficient vehicle 120 among the supply available stores 110. .

  Thereby, since the part which the electric power shortage vehicle 120 detours with respect to the original operation route can be made small, it can set as an appropriate operation route for supply.

  In addition, when the data center 140 creates a supply operation route and there are a plurality of power-deficient vehicles 120 heading for the supply-available stores 110 that are preferentially determined, the data center 140 out of the plurality of power-deficient vehicles 120 For this reason, priority is given to the power supply to the power shortage vehicle 120 having the longest travel distance or the power shortage vehicle 120 having the highest load cost per travel distance.

  Thereby, the selection which provided the importance with respect to the some electric power shortage vehicle 120 can be made easy.

  In addition, when the data center 140 creates a supply operation route and there are a plurality of power-deficient vehicles 120 heading for the supply-available stores 110 that are preferentially determined, the data center 140 is supplied from the plurality of power-deficient vehicles 120. It is also possible to give priority to the supply of electric power to the power-deficient vehicle 120 that has the highest degree of improvement in the degree of cleanness with respect to the environment due to the use of electric power.

  In this case, since the cleanliness with respect to the environment of the electric power shortage vehicle 120 can be improved, it can lead to the environmental improvement of the area | region where several stores 110A-110C are provided.

  In addition, when the data center 140 predicts the suppliable power amount, the data center 140 calculates the predicted power consumption amount based on the actual power consumption amount of the stores 110A to 110C in the past predetermined period before the current time. Therefore, the prediction accuracy of the suppliable electric energy can be improved.

  In addition, when the data center 140 predicts the suppliable power amount, the data center 140 calculates the predicted generated power amount based on the actual generated power amount of the solar power generation apparatus 111 in the past predetermined period before the current time. Therefore, the prediction accuracy of the suppliable electric energy can be improved.

  Further, when predicting the suppliable power amount, the data center 140 calculates the predicted amount of stored power based on the actual stored power amount of the store storage battery 112 in the past predetermined period before the current time. Therefore, the prediction accuracy of the suppliable power amount can be increased.

(Second Embodiment)
In the first embodiment, the collection / delivery center 130 that manages the operation of the delivery vehicles 120A to 120C is provided. Instead, each delivery vehicle 120A-120C is provided with communication means such as the operation planning unit 131 and the operation management unit 132 in the collection / delivery center 130 and communication means such as a data communication module (DCM). Operation route information and vehicle stored power amount data may be directly transmitted from 120C to the data center 140. At this time, the delivery vehicles 120A to 120C directly receive the power supply plan information transmitted from the data center 140.

  Thereby, the collection and delivery center 130 is not required, and the power supply system can be formed by the stores 110A to 110C, the delivery vehicles 120A to 120C, and the data center 140.

(Third embodiment)
When calculating the supply operation route, the data center 140 may newly determine a route that goes around in order from the supplyable store 110 having the largest supplyable power amount among the supplyable stores 110. As a result, even if there is a shortage in the power supply from the store 110 that can supply the power required by the power shortage vehicle 120, it is possible to cope with the shortage. Note that the shortage of power supply is supplied at the next supplyable store 110.

(Fourth embodiment)
When the data center 140 calculates the supply operation route, if the amount of power required by the power-deficient vehicle 120 cannot be covered by the amount of power supplied by the store 110 that can be supplied, the power distribution system at the store 110 that can be supplied. The supply power amount may be set to supply power using commercial power from As a result, even if it is not possible to cover the power shortage vehicle 120 with the power supply amount obtained by surplus, the power shortage vehicle 120 needs power because it uses easily available commercial power to supply power. The required amount of electric power for the vehicle can be supplied reliably.

(Other embodiments)
When the data center 140 issues a command to execute power supply, the data center 140 predicts the stop time for loading and unloading the luggage of the power-deficient car 120, and indicates the power supply speed in the store 110 that can be supplied according to the stop time. You may make it do. In other words, in the power supply plan from the data center 140, the charging time is taken into account, but the stopping time is predicted from the working time such as loading and unloading the luggage of the power-deficient vehicle 120, and the charging speed (charging mode) is calculated from the predicted stopping time. : Low / Medium / High). In this case, according to the characteristics of the vehicle storage battery 122, a method of efficiently preventing the deterioration of the vehicle storage battery 122 is taken, and the charging speed, charging time, and charge amount are instructed.

  As a result, power supply that effectively uses the stop time of the power-deficient vehicle 120 becomes possible, so that it is possible to suppress an increase in the stop time by supplying power.

  Further, the data center 140 may instruct the delivery vehicles 120A to 120C to change the operation mode of the vehicle electrical device according to the region or time zone in which the delivery vehicles 120A to 120C travel. For example, in consideration of the fact that an electric compressor of a refrigeration vehicle does not need to be kept cold if it is empty, it instructs the driving of the belt-driven compressor. Also, in a residential area, in order to prevent noise, the vehicle storage battery 122 is instructed to drive the electric compressor, and if it is only necessary to return using an expressway or the like, it is necessary to drive only the belt-driven compressor. . Furthermore, it is also possible to recognize a travel region / time zone at the data center 140 and to instruct an operation plan that switches an operation mode (silent / normal / rapid cooling) such as a refrigeration cycle.

  As a result, by changing the operation mode of the vehicle electrical device according to the region and time zone, the power required for operation of the vehicle electrical device and the noise level generated at the time of operation are suitable for the region and time zone. Since the value can be adjusted, power saving and noise reduction are possible.

  In addition, the data center 140 sequentially obtains the information on the stored power in the stores 110A to 110C and the information on the vehicle stored power in the delivery vehicles 120A to 120C, and according to the information on the stored power and the information on the vehicle stored power. The operation route for supply may be updated dynamically.

  That is, as power is supplied from the supplyable store 110 to the power-deficient vehicle 120, the stored power amount and the vehicle stored power amount change with the passage of time. Basically, by updating the operation route for supply, it is possible to supply power optimally at that time.

  Further, the data center 140 may update the supply operation route according to the amount of luggage in the power-deficient vehicle 120 and the congestion information on the supply operation route.

  In other words, the amount of luggage in the power-deficient vehicle 120 and the traffic congestion situation on the supply operation route change from moment to moment, so the supply operation route is determined based on the amount of luggage and the traffic jam information. By renewing, it becomes possible to supply power optimally at that time.

  Further, even if the data center 140 supplies power to the power-deficient vehicle 120 from the supply capable store 110 and there is still surplus due to the generated power, the data center 140 can supply the surplus to the power system. 110 may be instructed.

  In this way, even if power is supplied to the power-deficient vehicle 120 in the supply available store 110, the surplus power obtained at the supply available store 110 is fully utilized by selling power for the surplus. be able to. In addition, you can earn money from selling electricity.

  In addition, the data center 140 uses the power usage for which the power balance is excessive when the selling price of the generated power in the power system is higher than a predetermined price, to supply power to the delivery vehicles 120A to 120C and to the power system. In other words, the ratio between the amount of power used for power supply and the amount of power used for power sale may be adjusted according to the power sale price. For example, the higher the power selling price is, the more power is used for selling power than the amount of power used for supplying power. Thereby, the monetary profit by power sale can be expanded.

  In addition, if there is still surplus due to the generated power even if the data center 140 supplies power to the power-deficient vehicle 120 from the supplyable store 110, the data center 140 uses the surplus for generation of high-temperature hot water by the electric water heater. In this way, the supplyable store 110 may be commanded. Thereby, high temperature hot water can be produced | generated from surplus electric power, can be utilized as thermal energy, and the utilization range of energy can be expanded.
