  In some cases, used secondary batteries still store electrical energy, and if this electrical energy is used, the amount of carbon dioxide emissions associated with the generation of electrical energy can be reduced. In addition, when a new secondary battery is manufactured, carbon dioxide is discharged along with the manufacture of the secondary battery. However, if a used secondary battery is used, there is no need to manufacture a new secondary battery. Emissions can be reduced.

  The management device according to the first invention of the present application includes a memory and a controller. The memory stores information related to the reusable power storage element. The controller determines a supply destination of the storage element in response to input of supply information regarding supply of the storage element. Here, the controller determines the supply destination of the power storage element based on the carbon dioxide emission status of the supply destination included in the supply information and the priority rule. According to the priority rule, the higher the carbon dioxide emission amount, the higher the priority when determining the storage device supply destination.

  As a priority rule, the higher the ratio of the current carbon dioxide emission to the carbon dioxide emission target, the higher the priority. Specifically, the priority can be increased as the current emission amount approaches the emission target or the current emission amount exceeds the emission target. The controller can output information relating to the determination of the supply destination to the side that receives the supply of the storage element.

  As the power storage element, a power storage element in which electrical energy is stored in advance can be used. A power storage element that is determined to be reusable may still store electrical energy. Therefore, if the electrical energy stored in the electricity storage element is used at the supply destination, it is possible to prevent the discharge of carbon dioxide accompanying the generation of electrical energy, and to reduce the amount of carbon dioxide emission at the supply destination. Can do.

  As the power storage element, a power storage element mounted on a vehicle and outputting energy used for traveling of the vehicle can be used. Here, when the power storage element is mounted on a hybrid vehicle, electrical energy may remain stored in the power storage element removed from the vehicle.

  The management system according to the second invention of the present application includes the management device according to the first invention of the present application and a transmission device. The transmission device transmits information on the reusable power storage element to the management device. The memory of the management device stores information transmitted from the transmission device. According to the second invention of the present application, by transmitting information related to the reusable power storage element to the management device, the power storage element can be a supply target to the supply destination.

  The management system according to the third invention of the present application includes the management device according to the first invention of the present application and a transmission / reception device. The transmission / reception device transmits supply information to the management device and receives information related to determination of a supply destination from the management device. According to the third invention of the present application, it is possible to confirm whether the supply destination can receive the supply of the storage element when the supply destination desires the supply of the storage element.

  A fourth invention of the present application is a management program executed by a computer, and has a first step and a second step. In the first step, information relating to the supply of reusable power storage elements is acquired. In the second step, the supply destination of the storage element is determined based on the carbon dioxide emission status of the supply destination included in the information acquired in the first step and the priority rule. According to the priority rule, the higher the carbon dioxide emission amount, the higher the priority when determining the supply order of the power storage elements.

In Example 1, it is a flowchart which shows the process in a supply information input terminal. 4 is a flowchart illustrating an operation of the battery management device in the first embodiment. In Example 1, it is a figure which shows a priority rule.

  Examples of the present invention will be described below.

  A battery management system that is Embodiment 1 of the present invention will be described. FIG. 1 is a schematic diagram illustrating a configuration of a battery management system. The battery management system 1 according to the present embodiment determines the battery supply order in accordance with the carbon dioxide emission status at the supply destination.

  The battery (storage element) to be supplied is a used battery that can be recycled. As the battery, a secondary battery such as a nickel metal hydride or lithium ion battery can be used. An electric double layer capacitor (capacitor) can be used instead of the secondary battery. Moreover, as a form of a battery, a single battery can be used, or an assembled battery composed of a plurality of single batteries can be used. The assembled battery can be configured, for example, by electrically connecting a plurality of single cells in series.

  As a battery to be recycled, for example, there is a secondary battery mounted on a vehicle. The electric energy output from the secondary battery is converted into kinetic energy for running the vehicle by a motor / generator. The kinetic energy generated during braking of the vehicle is converted into electric energy by the motor / generator, and this electric energy can be stored in the secondary battery.

  Vehicles equipped with secondary batteries include hybrid vehicles and electric vehicles. A hybrid vehicle is a vehicle that uses another power source such as an internal combustion engine or a fuel cell in addition to a secondary battery as a power source for running the vehicle. An electric vehicle is a vehicle that uses only a secondary battery as a power source of the vehicle.

  The battery supply destination is classified according to the region or the company that has set the emission target of carbon dioxide. The carbon dioxide emission target refers to the carbon dioxide emission amount (target value) when a predetermined period has elapsed.

  The emission target can be determined on the basis of how much the emission amount is reduced with respect to the predetermined emission amount. That is, an amount obtained by reducing the discharge amount by a reduction target from a predetermined discharge amount becomes the discharge target. As the predetermined emission amount, for example, the emission amount of carbon dioxide at a specific time in the past can be used. The discharge target may be different for each battery supply destination, or may be the same at a plurality of supply destinations.

  For example, when an emission target is set for each region, the battery is supplied to a specific region. A battery supplied to a specific area can be used in a company or a home that exists in the specific area. Examples of the region include each region when Japan is divided into a plurality of regions, each country, or each region when the world is divided into a plurality of regions. On the other hand, when the emission target is set for each company, the battery is supplied to the specific company.

  The battery management system 1 includes a battery management device 10, a battery information input terminal (transmission device) 20, and a supply information input terminal (transmission / reception device) 30. The battery management device 10 manages batteries to be recycled and determines a battery supply destination. The battery management apparatus 10 includes a CPU 11 as a controller and a database (DB) 12 as a memory. The CPU 11 controls the operation of the battery management device 10. The database 12 stores information related to batteries to be recycled.

  The battery information input terminal 20 and the supply information input terminal 30 are connected to the battery management apparatus 10 via the network 40. As the network 40, a dedicated network or the Internet can be used.

  The battery information input terminal 20 is used to input information regarding a battery to be recycled, and the information input to the battery information input terminal 20 is transmitted to the battery management apparatus 10 via the network 40. The database 12 of the battery management device 10 stores information transmitted from the battery information input terminal 20.

  The supply information input terminal 30 is used to input information related to the carbon dioxide emission status at the supply destination or to input information related to the battery to be supplied. The supply information input terminal 30 is provided for each supply destination. Information input to the supply information input terminal 30 is transmitted to the battery management device 10 via the network 40. The information about the battery may be information that can specify the battery to be supplied.

  In the present embodiment, information related to the battery to be supplied is transmitted from the supply information input terminal 30 to the battery management device 10, but information regarding the battery may not be transmitted to the battery management device 10. . That is, only the information related to the carbon dioxide emission status can be transmitted to the battery management device 10.

  Next, processing in the battery information input terminal 20 will be described with reference to FIG.

  In step S101, information regarding the supplier is input. The information regarding the supply source is information for specifying the supply source of the battery to be recycled. Examples of the information on the supplier include the supplier's address and, when an identification number is assigned to each supplier, the supplier's identification number. By inputting information on the supply source, the battery supply source can be specified.

  In step S102, information related to when the battery can be delivered is input. Examples of information regarding the delivery time include a specific date and time and an expected period until delivery. In this embodiment, information related to when the battery can be delivered is transmitted to the battery management apparatus 10, but transmission of this information may be omitted.

  In step S103, information related to the battery to be delivered is input. The information related to the battery includes information for specifying the battery. As information specifying a battery, for example, when a battery name or an identification number is assigned to each battery, there is this identification number. The information related to the battery can include information related to the deterioration state of the battery. The deterioration state can be divided into a plurality of ranks based on a predetermined standard. When the deterioration state is divided into a plurality of ranks, information on each rank can be used as information on the deterioration state of the battery.

  The battery to be delivered is a recyclable battery. A battery whose deterioration state does not satisfy a predetermined standard, in other words, a battery that cannot be recycled, does not fall under a delivery target battery. As an index representing the deterioration state of the battery, for example, the current rate of change of the resistance value of the battery with respect to the resistance value of the battery in the initial state can be used. The initial state is a state immediately after the battery is manufactured. The resistance value of the battery can be calculated from the current value and voltage value of the battery.

  In step S104, the battery information input terminal 20 transmits the information input in steps S101 to S103 to the battery management device 10. For example, the operator of the battery information input terminal 20 can transmit the input information to the battery management apparatus 10 by inputting a transmission instruction after confirming the input information in steps S101 to S103.

  Information transmitted from the battery information input terminal 20 to the battery management apparatus 10 is stored in the database 12. In the database 12, the information input in steps S101 to S103 is stored in a state of being associated with each other.

  Next, processing in the supply information input terminal 30 will be described with reference to FIG.

  In step S201, information related to the supply destination is input. The information regarding the supply destination is information for specifying the supply destination. The information for specifying the supply destination includes, for example, an address of the supply destination or an identification number of the supply destination when an identification number is assigned to each supply destination. By inputting information about the supply destination, the battery supply destination can be specified.

  In step S202, information related to the time when battery supply is desired is input. Examples of the information regarding the supply time include a specific date and time and a period from when the supply is requested to when the supply is received. In this embodiment, information related to the time when battery supply is desired is input, but this information need not be input.

  In step S203, information related to the battery to be supplied is input. The information related to the battery includes information for specifying the battery. As information for specifying a battery, for example, when an identification number is assigned to each battery name and battery name, there is this identification number. In the present embodiment, the supply destination specifies the battery to be supplied, but the battery to be supplied need not be specified.

  In step S204, information regarding the carbon dioxide emission status at the supply destination is input. The information on the emission status is information indicating the relationship between the carbon dioxide emission target and the current carbon dioxide emission amount.

  For example, when the current emission amount already exceeds the emission target, information indicating that the emission target has already been exceeded is used as the information regarding the emission status. Further, when the current emission amount does not reach the emission target but is predicted to exceed the emission target in the future, information indicating that the emission target is scheduled to be exceeded is used as information regarding the emission status.

  When the current emission amount does not reach the emission target and it is predicted that the emission target will not be reached in the future, information indicating that the emission target is not exceeded is used as information on the emission status. In addition, when it is clear that the current emission amount has not reached the emission target and will not reach the emission target in the future, information indicating that the emission target is not exceeded is used as information regarding the emission status.

  Information relating to the above-described discharge status can be selected by the operator at the supply information input terminal 30. On the other hand, information specifying the emission target of carbon dioxide and the current emission amount can also be input.

  In the present embodiment, the information on the emission status includes information indicating whether there is an alternative means for reducing carbon dioxide. An alternative means is an alternative to a means for reducing carbon dioxide emissions using a battery. As an alternative means, for example, there is a means capable of reducing the amount of electric energy used. By reducing the amount of electric energy used, carbon dioxide emissions can be reduced. For example, if the power consumption of the apparatus can be reduced by improving the apparatus, the amount of electric energy used can be reduced. Here, the reduction of power consumption accompanying the improvement of the apparatus is an alternative means described above.

  In step S205, the supply information input terminal 30 transmits the information input in steps S201 to S204 to the battery management device 10. For example, the operator of the supply information input terminal 30 can transmit the input information to the battery management apparatus 10 by inputting a transmission instruction after confirming the input information in steps S201 to S204.

  Information transmitted from the supply information input terminal 30 to the battery management apparatus 10 is stored in the database 12. In the database 12, the information input in steps S201 to S204 in FIG. 3 is stored in a state of being associated with each other.

  Next, the process in the battery management apparatus 10 is demonstrated using FIG. The process shown in FIG. 4 is a process when information from the supply information input terminal 30 is received.

  When the CPU 11 executes a program stored in the memory of the battery management device 10, the process shown in FIG. 4 is performed. This program can be stored and handled in a recording medium. Moreover, a program can also be downloaded to the battery management apparatus 10 using a network.

  In step S <b> 301, the CPU 11 stores the information transmitted from the supply information input terminal 30 in the database 12. In step S302, the CPU 11 receives information from the supply information input terminal 30 and searches for a battery corresponding to this information.

  The database 12 stores information received from the battery information input terminal 20. The CPU 11 uses the information stored in the database 12 to determine whether there is a battery that matches the information received from the supply information input terminal 30.

  When the information received from the battery information input terminal 20 (information specifying the battery) matches the information received from the supply information input terminal 30 (information specifying the battery), the CPU 11 has a battery to be supplied. Judge that. On the other hand, when the information received from the battery information input terminal 20 (information specifying the battery) and the information received from the supply information input terminal 30 (information specifying the battery) do not match, the CPU 11 supplies the battery to be supplied. Is determined not to exist.

  When there is a battery to be supplied, the processes after step S303 are performed. On the other hand, when there is no battery to be supplied, the battery management device 10 transmits information indicating that no battery is present to the supply information input terminal 30. In this embodiment, the battery to be supplied is specified at the supply destination. However, when the battery to be supplied is not specified, the process of step S302 is omitted.

  In step S <b> 303, the CPU 11 reads the priority rule stored in the database 12. The priority rule is a rule for determining the order of supply destinations of the secondary batteries, and can be stored in the database 12 in advance. The priority rules stored in the database 12 can be changed as appropriate.

  In step S <b> 304, the CPU 11 determines the order of battery supply destinations using the information regarding the carbon dioxide emission status among the information transmitted from the supply information input terminal 30 and the priority rule read in step S <b> 303. .

  In this embodiment, the CPU 11 determines the order of battery supply destinations based on the priority rules shown in FIG. In the priority rule shown in FIG. 5, the higher the ratio of the current discharge amount to the discharge target, the higher the priority when determining the battery supply order. That is, as the current discharge amount approaches the discharge target and the current discharge amount exceeds the discharge target, the priority in determining the battery supply order becomes higher.

  In the priority rule shown in FIG. 5, a supplier whose carbon dioxide emissions already exceed the emission target has a higher priority than a supplier whose carbon dioxide emissions are scheduled to exceed the emission target. A supplier whose emission amount is scheduled to exceed the emission target has a higher priority than a supplier whose emission amount is not expected to exceed the emission target. Furthermore, a supplier whose emission amount does not exceed the emission target has a higher priority than a supplier whose emission amount does not exceed the emission target.

  On the other hand, a supply destination without an alternative means for reducing carbon dioxide has a higher priority than a supply destination with an alternative means. In this embodiment, the priorities are made different depending on whether or not there is an alternative means, but it is not necessary to consider the presence or absence of the alternative means when determining the priority order.

  In the present embodiment, when a plurality of supply destinations desire to supply the same battery, the supply order of the batteries is determined for the plurality of supply destinations based on the above-described priority rule. Further, even if it is determined that the battery is supplied to the supply destination with the highest priority, if there is a remaining battery, it is determined that the battery is supplied to the supply destination with the next highest priority. On the other hand, when only a specific supply destination desires to supply a specific battery, the battery is supplied to the specific supply destination. Here, when the battery to be supplied is not specified, the battery supply destination is determined based on the above-described priority rule.

  In this embodiment, the priority rule is determined on the assumption that the carbon dioxide emission target is set in the supply destination, but the priority rule is not limited thereto. For example, the priority rule can be determined by paying attention only to the discharge amount of the supply destination. Specifically, it is possible to use a priority rule that increases the priority when determining the battery supply order as the amount of carbon dioxide emission increases. In this case, it is only necessary to input information specifying the carbon dioxide emission amount to the supply information input terminal 30.

  In step S <b> 305, the CPU 11 transmits information regarding the order of the supply destination determined in step S <b> 304 to the supply information input terminal 30. Information regarding the order of the supply destinations is transmitted to all supply destinations (supply information input terminal 30) that desire to supply batteries. Here, when the information regarding the deterioration state of the battery is stored in the database 12, the information regarding the deterioration state can be transmitted together with the information regarding the order of the supply destination. Further, when the supply destination does not specify the battery to be supplied, information for specifying the battery can be transmitted to the supply destination (supply information input terminal 30).

  Supply information input terminal 30 receives the information transmitted from battery management device 10 and displays the received information on the display. The display may be configured integrally with the supply information input terminal 30 or may be connected to the supply information input terminal 30. The operator of the supply information input terminal 30 can confirm the order in which the batteries are supplied by confirming display information on the display.

  Here, when the information regarding the deterioration state of the battery is transmitted from the battery management device 10, the deterioration state of the battery can be confirmed. Further, when the supply target battery is not specified at the supply destination, the battery to be supplied can be confirmed by acquiring information for specifying the battery from the battery management device 10.

  According to the present embodiment, the battery can be effectively used by supplying the battery to be recycled to the supply destination. In addition, by determining the battery supply destination in descending order of the current emission rate relative to the emission target, the carbon dioxide emission amount at the supply destination can be reduced.

  Specifically, if a battery to be recycled is supplied, there is no need to manufacture a new battery at the supply destination, and carbon dioxide emissions associated with battery manufacture can be prevented. Thereby, the discharge | emission amount of the carbon dioxide in a supply destination can be reduced.

  On the other hand, electric energy may remain stored in a battery to be recycled. In this case, by using a battery in which electric energy is stored at the supply destination, it is possible to prevent carbon dioxide emission accompanying the generation of electric energy, and to reduce the amount of carbon dioxide emission at the supply destination. be able to.

  For example, in a hybrid vehicle, charging / discharging of a secondary battery is controlled based on a predetermined SOC (State Of Charge) reference value. Specifically, when the current SOC is higher than the reference value, the secondary battery is positively allowed to discharge so that the SOC approaches the reference value. Further, when the current SOC is lower than the reference value, the secondary battery is positively allowed to be charged so that the SOC approaches the reference value.

  When the secondary battery is removed from the hybrid vehicle, the electric energy remains stored in the secondary battery, and the electric energy stored in the secondary battery can be used. Even if the vehicle is not a hybrid vehicle, some used secondary batteries still store electrical energy. If this secondary battery is supplied to the supply destination, the electrical energy stored in the secondary battery can be used at the supply destination.

  Conventionally, a secondary battery removed from a hybrid vehicle may be discarded after being forcibly discharged. Here, the electrical energy when the secondary battery was discharged was not reused and was wasted. In this embodiment, the electrical energy can be effectively utilized by reusing the electrical energy stored in the secondary battery.

  In this embodiment, when a battery is supplied from a supply source to a supply destination, the battery can be supplied to the supply destination after the supply source is charged to a fully charged state. For example, when the emission amount of carbon dioxide at the supply source is smaller than the emission amount of carbon dioxide at the supply destination, the electrical energy of the supply source is supplied to the supply destination via the battery, so that the supply source and the supply destination Variations in carbon dioxide emissions can be suppressed. That is, the supply source and the supply destination can cooperate with each other to achieve the carbon dioxide emission target.
