Description

  The present invention relates to an electric vehicle charging and charging method and an electric vehicle charging and charging system.

  In the automotive field, the driving force of a motor driven by the power of a battery (battery) charged from an automobile that uses conventional petroleum energy such as gasoline and light oil and drives the engine by burning petroleum energy is the driving force. The shift to electric vehicles (EVs) is underway. With the commercialization of electric vehicles, demand for charging facilities for electric vehicles is increasing. Therefore, like a conventional gas station, there is a demand for an environment where a charging service station is installed in each region and a quick charge can be freely performed when a customer (user) wants to charge.

  On the other hand, there are the following problems with respect to the charging method for rapid charging in order to implement the pay-as-you-go system. One is that there is no DC meter that can be used for power trading. In an electric vehicle, direct current power is used instead of alternating current power for household use or commercial power. For this reason, if there is no DC meter, metering will be difficult. Another problem is that it is difficult to use “kWh” as a transaction unit from the viewpoint of the measurement law. It is also conceivable to construct a circuit that can be measured with a certified AC meter (see, for example, Patent Document 1), but when measured with such a circuit, the conversion loss of the quick charger is included in the measured quantity. There is a problem such as. Due to the problems described above, conventionally, a method such as a flat-rate billing per time or a method such as a monthly flat-rate billing has been adopted.

  However, in the flat-rate billing method, there is a problem that fairness may be lost because the customer (customer) is charged regardless of the amount of power charged.

Embodiment 1 FIG.
FIG. 1 is an example of a configuration diagram showing a configuration of a charging / charging system for an electric vehicle in the first embodiment. In FIG. 1, a charging system 100 includes a charging service management device 10 (first management device), a charging service station (SS) 20, a car information management device 40 (second management device), and a content creation device 50. I have. The charging service management device 10, the charging service station (SS) 20, the vehicle information management device 40, and the content creation device 50 are arranged to be able to communicate with each other via the Internet (an example of a network). The charging service management device 10 is communicably connected to the local power saving management device 80 and the credit company communication device 70 via the Internet (an example of a network).

  The charging service station 20 is provided with a quick charger 22 (an example of a charger). In addition, a user (customer) of the electric vehicle 32 rides (arrives) at one or more charging service stations 20 arranged in the area with the electric vehicle (EV) 32, and the electric charger 32 in the electric vehicle 32 from the quick charger 22. The battery 38 (battery) is charged. In the electric vehicle 32, an in-vehicle device 36 that can communicate with the vehicle information management device 40 via a base station 60 arranged in each region is mounted. A user (customer) of the electric vehicle 32 has a portable terminal 34 and an authentication card 37.

  The regional power saving management device 80 is communicably connected to a plurality of load devices 82 and a plurality of power plants 84 via the Internet (an example of a network). The regional power saving management device 80 is arranged for each region. For example, it is arranged for each municipality such as Kitakyushu city, Sapporo city, Kanazawa city. However, the present invention is not limited to this. What is necessary is just to arrange | position by the unit of the supply-and-demand area which covers the demand and supply of electric power.

  Examples of the plurality of load devices 82 include an energy management device installed in a home for home use, an energy management device installed in an apartment house such as a condominium, or an energy management device installed in a commercial building. be able to. Each load device 82 receives supply of power (AC power such as AC 100V or 200V) from the facilities of the power supply company, and transmits the power used to the local power saving management device 80 in real time or periodically. For example, power used (for example, “kWh unit” power) is transmitted to the regional power saving management device 80 every 30 minutes.

  Examples of the plurality of power plants 84 include power generation facilities such as a thermal power plant, a hydro power plant, a geothermal power plant, a wind power plant, and a substation that supply power to the corresponding area. In addition, there are a machine itself that supplies power by distributing relatively small power generators near a consumption area, and a distributed power generator such as the system. Distributed power generators have a variety of power sources ranging from small and medium-scale power generation facilities centered on grid interconnection to secondary power transmission systems, to small-scale low-power generators such as solar, wind, and fuel cells. Is included. Each power plant 84 transmits information on the amount of power that can be generated to the regional power saving management device 80 in real time or periodically. For example, the power generation amount (for example, “kWh unit power”) is transmitted to the regional power saving management device 80 every 30 minutes.

  As described above, there is a problem in metering the quick charge to the battery 38 of the electric vehicle 32. Therefore, various charging methods as described below were examined. Hereinafter, the examination results will be described.

  FIG. 2 is a graph showing an example of the relationship between the charging rate and the charging time as a comparative example of the first embodiment. Here, a method of charging for the charging time will be described. In FIG. 2, the vertical axis indicates the charging rate, the charging current, and the charging voltage of the battery 38 of the electric vehicle 32, and the horizontal axis indicates the charging time (elapsed time). As shown in FIG. 2, in the rapid charging of the battery 38 of the electric vehicle 32, the amount of power that can be charged per hour is greatly different. This lacks fairness and is not appropriate.

  A method of charging by the number of times of charging will be described. In such a system, it is difficult to make a pay-as-you-go charge because the amount of charge at each time is unknown. This lacks fairness and is not appropriate.

  Therefore, in the first embodiment, the change in the remaining power (SOC) of the battery 38 measured by the electric vehicle 32 is used. Charges similar to pay-as-you-go charges are implemented by changing the SOC. If the SOC is changed, it is possible to charge with a value based on the charged net electric energy without including the conversion loss of the quick charger 22. Set the charge per SOC ratio. For example, assuming that 250 yen / SOC 10% (or 25 yen / SOC 1%), when charging is performed so that the change in SOC is 20% to 80%, the charge is 1500 yen.

  Further, in the first embodiment, the power price is changed for each region according to the power supply balance. This guides residents' behavior from an economic perspective.

  FIG. 3 is a diagram showing an example of the relationship between local power demand and price in the first embodiment. In the example of FIG. 3A, for example, when the power demand in the area is low, the power price (electricity charge) is lowered. On the contrary, when the electric power demand in the area is high, the electric power price (electricity charge) is given. As shown in FIG. 3B, a low (cheap) charge when the power demand in the area is low is set as a high charge when the power demand in the area is high. For example, such a change in the charge is changed according to the time zone in one day. This concept is also applied to the charge for electric vehicles. For this purpose, the local power saving management device 80 uses the information on the power used from each load device 82 and the information on the power supplied from each power plant 84.

  First, the local power saving management device 80 inputs the information on the power used from each load device 82 and the information on the power supplied from each power plant 84 at real time or at regular intervals obtained by subdividing the time of the day. Then, the regional power saving management device 80 sets a power charge (electricity charge) every predetermined time, for example, in accordance with the ratio of the used power to the power that can be supplied. For example, a charge (yen) per 1 kWh of electric power is set. Then, a fee table (1) (first fee table) defining the fee for each hour is created using the set fee as the fee for the next day of the information input date. In other words, the charge table (1) is created using the energy usage record on the day before the day when each charge defined in the charge table (1) is applied. Furthermore, the charge table (1) varies according to the amount of energy that can be supplied from the power plant 84 (power generation device). In this way, the charge table (1) is created using the actual energy usage by a plurality of load devices 82 different from the electric vehicle 32. At the same time, the charge table (1) is created using the amount of energy that can be supplied from the power plant 84 (power generation device).

  FIG. 4 is a diagram showing an example of the charge table (1) in the first embodiment. FIG. 4 shows an example of a charge table (1) in which the charge changes according to time. For example, the fee is set every 30 minutes. In FIG. 4, the vertical axis indicates the charge per electric power (yen / kWh), and the horizontal axis indicates the time zone for one day. In the example of FIG. 4, for example, from “midnight” to dawn, which is “off-peak”, similar to the basic charge (basic) indicated by the dotted line, a low price is set. For example, in the morning period corresponding to “middle”, a lower fee is set that is cheaper than the basic fee (basic) indicated by a dotted line. In the morning time zone, it is preferable to change the charge assuming that demand is different between the first half and the second half. For example, during the afternoon of the day, which corresponds to “peak”, the charge varies in three levels, for example, levels 1 to 3 according to the level of demand. Then, for example, from the evening to the middle of the night corresponding to “middle”, as in the morning, for example, it is set at a lower price that is cheaper than the basic charge (basic). For example, at midnight, which corresponds to “off-peak”, a low-priced, low-priced charge is set in the same manner as the basic charge (basic). For example, for each charge after the evening, it is assumed that there will be no significant change in the supply and demand situation from day to day, so the charge table (1) is just around the peak time when the supply and demand situation is likely to change. It is preferred that it be created in time.

  FIG. 5 is a configuration diagram illustrating an example of an internal configuration of the charging service management apparatus according to the first embodiment. 5, in the charging service management device 10, storage devices 110, 114, 115 such as a magnetic disk device, a collation unit 111, a charge availability determination unit 113, an output unit 117, a charge table creation unit 112, a charge table output unit 116, a remaining power storage (SOC) difference input unit 118, a charge calculation unit 119, a charge totaling unit 210, and a memory 211 are arranged. Functions such as collation unit 111, chargeability determination unit 113, output unit 117, charge table creation unit 112, charge table output unit 116, remaining power (SOC) difference input unit 118, charge calculation unit 119, and charge totaling unit 210 May be configured by software such as a program. Alternatively, it may be configured by hardware such as an electronic circuit. Alternatively, a combination thereof may be used. Input data required in the charging service management apparatus 10 or the calculated result is stored in the memory 211 each time.

  FIG. 6 is a time chart showing a main part communication flow of the charge accounting method in the first embodiment. FIG. 6 shows an example of a communication status among the regional power saving management device 80, the charging service management device 10, the charging service station (SS) 20, the user side 30, the vehicle information management device 40, and the content creation device 50.

  The regional power saving management device 80 transmits the created fee table (1) to the charging service management device 10 via the Internet (an example of a network) the day before each fee defined in the fee table (1) is applied. For example, it is suitable to transmit around the evening of the previous day. The charging service management device 10 receives the charge table (1) on the previous day and stores it in the storage device 110. The regional power saving management device 80 creates a fee table (1) that defines a fee for each hour applied every day, and transmits it to the charging service management device 10 on the created date. Therefore, each charge in the charge table (1) varies daily depending on the supply and demand situation. Therefore, the variable charge table (1) (first charge table) input from the outside is stored in the storage device 110 (storage unit).

  In the charging service management apparatus 10, the charge table creation unit 112 uses the charge table (1) to convert each charge defined in the charge table (1) into the remaining charge (SOC) of the battery 38 mounted on the electric vehicle. ) A fee table (2) (second fee table) in which each fee converted into a fee per rate is defined is created. The fee table creation unit 112 creates a corresponding fee table (2) on the day when the fee table (1) is received. Each fee defined in the fee table (2) is applied as a fee the day after the date of creation. Therefore, the fee table (2) is created on the day before the day on which each fee defined in the fee table (2) is applied.

FIG. 7 is a diagram showing an example of the charge table (2) in the first embodiment. FIG. 7 shows an example of a charge table (2) in which the charge changes according to time. For example, the fee is set every 30 minutes. In FIG. 7, the vertical axis shows the charge per SOC ratio (yen / SOC%), and the horizontal axis shows the time zone for one day. Each Rate _{T 2} of the fee table (2), using the rates _{T 1} of the charge table (1), for example, is defined by the following equation (1).
(1) T ₂ = k · T ₁

In equation (1), which converts each fee T ₁ of the charge table (1) to each fee T ₂ of the fee table (2) using the coefficient k. Thus, also the rates T ₂ of the fee table (2), can be a value of daily variable according to supply and demand of electric power. Therefore, the electric power supplied to the electric vehicle can be flexibly operated according to the demand situation that varies depending on each region and time zone. Therefore, the service can be provided to the consumer (customer) at a fair fee according to the demand situation. In the example of FIG. 7, as in the example of FIG. 4, for example, from midnight to dawn, which is “off-peak”, similar to the standard fee (basic) indicated by the dotted line, it is set at a low price. For example, in the morning period corresponding to “middle”, a lower fee is set that is cheaper than the basic fee (basic) indicated by a dotted line. In the morning time zone, it is preferable to change the charge assuming that demand is different between the first half and the second half. For example, during the afternoon of the day, which corresponds to “peak”, the charge varies in three levels, for example, levels 1 to 3 according to the level of demand. Then, for example, from the evening to the middle of the night corresponding to “middle”, as in the morning, for example, it is set at a lower price that is cheaper than the basic charge (basic). For example, at midnight, which corresponds to “off-peak”, a low-priced, low-priced charge is set in the same manner as the basic charge (basic).

  Here, the amount of electric power per 1% SOC varies depending on the type of the electric vehicle or the storage size of the battery mounted on the electric vehicle. Therefore, in the first embodiment, a charge table (2) is created for each type of electric vehicle or for each storage size of a battery mounted on the electric vehicle. In this way, the fee table creation unit 112 creates a plurality of fee tables (2). The created plurality of fee tables (2) are temporarily stored in the storage device 114. And the charge table output part 116 (output part) reads the information of the produced several charge table (2) from the memory | storage device 114, and the internet (an example of a network) is made to the vehicle information management apparatus 40 on the created day. Send (output) via.

  FIG. 8 is a configuration diagram illustrating an example of an internal configuration of the vehicle information management device according to the first embodiment. 8, in the car information management device 40, there are a charge table input / output unit 140, a memory 141, an identification information (ID) input unit 142, a storage device 143 such as a magnetic disk device, a collation unit 144, an input / output unit 145, An SOC difference calculation unit 146 and a collation unit 147 are arranged. Each function such as the fee table input / output unit 140, the identification information (ID) input unit 142, the collation unit 144, the input / output unit 145, the SOC difference calculation unit 146, and the collation unit 147 may be configured by software such as a program. Alternatively, it may be configured by hardware such as an electronic circuit. Alternatively, a combination thereof may be used. Necessary input data in the vehicle information management device 40 or calculated results are stored in the memory 141 each time.

  In the vehicle information management device 40, the charge table input / output unit 140 is created by the charge service management device 10 for each type of electric vehicle or for each storage size of a battery mounted on the electric vehicle. (2) is received (input), and transmitted (output) to the content creation device 50 via the Internet (an example of a network) on the day when the information of the plurality of charge tables (2) is received.

  FIG. 9 is a configuration diagram illustrating an example of an internal configuration of the content creation device according to the first embodiment. In FIG. 9, a fee table content creation unit 151, storage devices 152 and 154 such as a magnetic disk device, a charging result content creation unit 153, an output unit 155, and a memory 156 are arranged in the content creation device 50. Each function such as the charge table content creation unit 151, the charging result content creation unit 153, and the output unit 155 may be configured by software such as a program. Alternatively, it may be configured by hardware such as an electronic circuit. Alternatively, a combination thereof may be used. Necessary input data in the content creation device 50 or the calculated result is stored in the memory 156 each time.

  In the content creation device 50, the charge table content creation unit 151 includes a plurality of charge tables (for each vehicle type of the electric vehicle or each storage size of the battery mounted on the electric vehicle from the vehicle information management device 40. 2) is received (input), and fee table contents indicating the contents of the fee table (2) are created for each type of electric vehicle or for each storage size of a battery mounted on the electric vehicle. The created charge table contents for each type of electric vehicle or for each storage size of a battery mounted on the electric vehicle are stored in the storage device 152. Then, the output unit 155 reads the information of the created plurality of fee table contents from the storage device 152, and sends the Internet (an example of a network) to the portable terminal 34 of the user (customer) of the electric vehicle on the date of creation. Distributed (output) via In addition, what is necessary is just to be delivered to the user's (customer's) mobile terminal 34 by wireless communication from the base station 60 arranged at the place where the mobile terminal 34 is located. In the example of FIG. 1, the base station that communicates with the vehicle-mounted device 36 and the base station that communicates with the mobile terminal 34 are indicated by the same base station 60, but may be different. The base station that communicates with the portable terminal 34 may be any device that allows the portable terminal 34 to connect to the Internet.

  In the example of FIG. 1, one charging service station (SS) 20 is shown in one area, but a plurality of charging service stations (SS) 20 may be arranged, and the charging service station (SS) 20 Each fee may be different. In such a case, the charging service management apparatus 10 may create a plurality of fee tables (2) for each charging service station (SS) 20. Then, the charge table content with the location of the charging service station (SS) 20 and the like may be distributed to the mobile terminal 34 via the vehicle information management device 40 and the content creation device 50. Alternatively, a system similar to that shown in FIG. 1 may be configured in a plurality of regions, and similar fee table contents may be created. And the area | region of the charge charge to display should just select a user arbitrarily.

  Therefore, the user (customer) can know the charge rate of the next day within the previous day. As a result, it is possible to obtain a charge rate close to a metered rate, which cannot be obtained by the conventional flat-rate billing method, but changes flexibly according to the demand situation which varies depending on each region and time zone. Therefore, it is possible to know a fair charge charge as compared with the fixed charge method. Thereby, the user (customer) can determine whether the battery mounted in the electric vehicle is charged the next day. In addition, the user (customer) can use an electric vehicle that is variably set according to the local supply and demand situation based on the energy usage record by the load devices 82 different from the electric vehicle and the amount of power that can be supplied from the power plant 84. You can know the charge. Such information is usually distributed every day. Therefore, the user (customer) can obtain an indicator for determining when to charge. Furthermore, a user (customer) can charge a battery mounted on an electric vehicle on a cheap day, and provide the battery as one of the power plants 84 as a regional distributed power generation device. . Or it becomes possible to use the electric power of this battery as household electric power of a user (customer).

  Here, the power supply status may change from moment to moment depending on the weather or the like. It also changes due to sudden accidents. Therefore, the first embodiment is configured such that the charges in each time zone can be changed variably also on the day when the charges in the plurality of charge tables (2) are applied.

  For each charge defined in the charge table (1) that has already been transmitted the previous day, the local power saving management device 80 uses the charge table based on the actual energy usage or / and the amount of power that can be supplied. Spot fee information (1) (yen / kWh) in which the amount of money is corrected is created for a part of each fee defined in (1). The created spot fee information (1) (yen / kWh) is immediately transmitted to the charging service management apparatus 10 via the Internet (an example of a network). For example, it is preferable that the data is transmitted several hours before the time zone to be changed. If it can be created by the morning, for example, it may be transmitted by about 8:00 when many users (customers) start activities.

  In the charging service management apparatus 10, the charge table creation unit 112 determines each charge defined in the charge table (1) based on the actual energy usage on the day to which each charge defined in the charge table (1) is applied. The spot fee information (1) about the fee is received (input) in a part of the information and stored in the storage device 110. Then, the spot fee information (1) is read from the storage device 110, and converted into a fee per SOC ratio for each type of electric vehicle or for each storage size of the battery mounted on the electric vehicle, and the converted fee has already been converted. Overwrite the corresponding fee among the fees defined in each created fee table (2). As a result, the plurality of fee tables (2) created for each type of electric vehicle or each storage size of the battery mounted on the electric vehicle is updated on the day when each defined fee is applied.

  Then, the charge table output unit 116 reads the updated information of the plurality of charge tables (2) from the storage device 114, and transmits the Internet (an example of a network) to the vehicle information management device 40 as quickly as possible during the day. To send (output). For example, it is preferable that the data is transmitted several hours before the time zone to be changed. If it can be updated by the morning, for example, it may be transmitted by about 8:00 when many users (customers) start activities.

  In the vehicle information management device 40, the charge table input / output unit 140 receives (inputs) the updated plurality of charge tables (2) and promptly receives the information from the plurality of charge tables (2) as soon as possible. Then, it is transmitted (output) to the content creation device 50 via the Internet (an example of a network).

  In the content creation device 50, the fee table content creation unit 151 receives (inputs) the updated plurality of fee tables (2) from the vehicle information management device 40, and updates the contents of the delivered fee table content. To do. The updated charge table contents for each type of electric vehicle or each storage size of the battery mounted on the electric vehicle are stored in the storage device 152. Then, the output unit 155 reads the updated information of the plurality of charge table contents from the storage device 152, and promptly transmits the Internet (an example of a network) to the portable terminal 34 of the user (customer) of the electric vehicle from the updated time. Deliver (output) via. In addition, what is necessary is just to be delivered to the user's (customer's) mobile terminal 34 by wireless communication from the base station 60 according to the location where the mobile terminal 34 is located.

  Therefore, the user (customer) can know the updated charging fee on the day. As a result, it is possible to obtain a charge rate close to a metered rate, which is changed by a change in the demand situation that differs depending on each region and time zone, which cannot be obtained by the conventional flat rate charging method. Therefore, the user (customer) can determine again whether or not to charge the battery mounted on the electric vehicle based on the latest information after the determination.

  As described above, the user who knows the charging fee of the variable electric vehicle determines whether or not to receive the charging service based on his / her own judgment. When receiving a charging service, it is configured as follows.

  When receiving the charging service, the user (customer) carries the authentication card 37 and goes to the charging service station (SS) 20 by an electric vehicle. Then, the user (customer) causes the quick charger 22 charged in the charging service station (SS) 20 to read the contents of the authentication card 37. For example, the authentication card 37 is put on the reader or touched.

  FIG. 10 is a configuration diagram illustrating an example of an internal configuration of the quick charger in the first embodiment. 10, in the quick charger 22, there are an authentication information input unit 120, an output unit 122, a charge determination unit 124, a charge control unit 126, a charging power supply unit 128, an SOC information input unit 130, an SOC difference calculation unit 132, an SOC.
