<First Embodiment>
<System configuration>
FIG. 1 is a diagram showing a configuration example of an OCV adjustment system SY (hereinafter referred to as a system SY) according to an embodiment. The system SY is a system for adjusting the OCV of the removed vehicle battery when the vehicle battery used in an electric vehicle represented by an electric vehicle is removed from the vehicle body and reused (secondary use). Is. In this embodiment, the system SY includes a server 1. Further, the system SY may include a vehicle 2, a terminal 3 of a user of the vehicle 2, a charging station 4, and a battery regeneration factory 5. The configuration of the system SY is an example and may be omitted or added as appropriate. Further, the broken line in FIG. 1 indicates the traveling path of the vehicle 2 when the OCV adjustment is performed by the system SY.

The server 1 performs a process for adjusting the OCV of the battery 21 when the battery 21 of the vehicle 2 is reused. The server 1 includes a processing unit 11, a storage unit 12, and a communication I / F unit 13 (communication interface unit).

The processing unit 11 is a processor typified by, for example, a CPU, and executes a program stored in the storage unit 12. The storage unit 12 includes, for example, a memory such as RAM and ROM and a relatively large-capacity storage device such as an HDD, and stores programs executed by the processing unit 11 as well as data and the like used by the processing unit 11 for processing. .. The communication I / F unit 13 relays communication between the processing unit 11 and an external device via a network NT such as the Internet.

Further, the storage unit 12 may form a database DB that manages information on the vehicle 2, the charging station 4, the battery regeneration factory 5, and the like. For example, the processing unit 11 may periodically acquire information on the usage status such as mileage and electricity cost from the vehicle 2 under control and update the database DB. Further, for example, the database DB may manage the location information of the battery regeneration factory 5 in association with information such as the inventory of the battery 21 and the acceptance / rejection of the new battery 21.

The vehicle 2 is an electric vehicle represented by an electric vehicle. The vehicle 2 includes a battery 21, a communication device 22, and a display unit 23. The battery 21 stores electricity to be supplied to an electric motor or the like as a power source for the vehicle 2. In the present embodiment, the battery 21 is configured to be used in the vehicle 2 and then removed from the vehicle 2 so that it can be reused for other purposes. In one embodiment, the battery 21 can be a lithium ion battery. The communication device 22 transmits / receives information to / from the server 1 and the like via the network NT. The display unit 23 is, for example, a liquid crystal display provided in the vehicle interior and displays various information. Note that FIG. 1 mainly shows the configuration related to the present embodiment among the configurations of the vehicle 2, and some configurations are omitted.

The terminal 3 is, for example, an information processing terminal such as a smartphone, a tablet, or a PC owned by the user of the vehicle 2. The terminal 3 includes a processing unit 31, a storage unit 32, a communication I / F unit 33, and a display unit 34.

The processing unit 31 is a processor typified by, for example, a CPU, and executes a program stored in the storage unit 32. The storage unit 12 is, for example, a memory such as a RAM or a ROM, and stores data or the like used by the processing unit 31 for processing in addition to a program executed by the processing unit 31. The communication I / F unit 33 relays communication between the processing unit 31 and an external device via a network NT such as the Internet. Further, the display unit 34 is, for example, a liquid crystal display or the like, and displays various information.

The charging station 4 is a station that charges and discharges the battery 21 mounted on the vehicle 2. In one embodiment, the charging station 4 is determined based on a communication device for communicating with an external device such as a server 1 or a vehicle 2 via a network NT, or information received from the server 1 or the vehicle 2 or the like by the communication device. A control device or the like for controlling the above may be provided. In this case, the control device may include a processor typified by a CPU, a storage unit such as RAM and ROM, an I / F unit that relays communication between the processor and an external device, and the like.

The battery recycling factory 5 is a collection place for the reused battery 21. For example, the reused battery 21 is carried into the battery recycling factory 5 together with the vehicle while being mounted on the vehicle 2. Then, the battery 21 is removed from the vehicle body at the battery recycling factory 5, and a plurality of batteries 21 are combined and provided to the reuse destination as needed. In one embodiment, the battery regeneration factory 5 is based on a communication device for communicating with an external device such as a server 1 or a vehicle 2 via a network NT, or information received from the server 1 or the vehicle 2 or the like by the communication device. A control device or the like that performs predetermined control may be provided. In this case, the control device may include a processor typified by a CPU, a storage unit such as RAM and ROM, an I / F unit that relays communication between the processor and an external device, and the like. Examples of the battery collection location include the battery recycling factory 5, the dealer of the vehicle 2, and the like.

By the way, when providing the battery 21 removed from the vehicle 2 to the reuse destination, if the initial value of the OCV of the battery 21 is determined such as X% or more of the upper limit voltage, the OCV adjustment of the removed battery 21 is performed. May be required. Further, in order to secure the battery capacity, batteries removed from a plurality of vehicles may be connected to each other to form a unit and used as one reuse battery. In such a case, if there is a difference in the OCV of each battery 21, a large current will flow at the time of connection, so it is necessary to adjust the OCV of the battery 21 before connecting the batteries.

If the OCV adjustment is performed on the battery 21 removed from the vehicle 2 each time, the work efficiency for providing the battery 21 to the reuse destination may decrease. In addition, a device for performing OCV adjustment is also required, which may complicate the work and increase the cost required for the work. Therefore, in the present embodiment, the OCV of the battery 21 is adjusted by the following method.

<Flow of battery OCV adjustment method by system>
FIG. 2 is a flowchart showing the overall flow of the OCV adjustment method of the battery 21 by the system SY.

In S1, the user of the vehicle 2 registers the reuse of the battery 21 mounted on the vehicle 2 by the user's terminal 3 or the like. For example, the user can sell the battery 21 by replacing the battery 21 of the vehicle 2 or by performing reuse registration when the vehicle 2 itself is sold or scrapped. At the time of reuse registration, the user can transmit the user's own information, the vehicle 2 information, and the like to the server 1. The reuse registration may be executed by the communication device 22 of the vehicle 2.

The server 1 that has received the reuse registration in S2 transmits an instruction to the user. For example, the server 1 sends an instruction to the terminal 3 or the vehicle 2 to move the vehicle 2 to the designated battery regeneration factory 5 after discharging and charging the battery 21 at the designated charging station 4. When the vehicle 2 is a vehicle that can be automatically moved to the battery regeneration factory 5, the server 1 may send a movement instruction to the battery regeneration factory 5 to the vehicle 2 instead of an instruction to the user. .. That is, the user does not necessarily have to recognize the collection location, and the server 1 may send an instruction so that the vehicle 2 can move to the battery regeneration factory 5 which is the collection location.

In S3, the user moves the vehicle 2 to the designated charging station 4 according to the instruction transmitted in S2. In S4, the user charges and discharges the battery 21. Details will be described later, but here, a predetermined amount determined by information such as the user's electricity cost, the distance from the charging station 4 to the battery recycling factory 5, and the OCV setting value of the battery 21 when the battery 21 is provided to the reuse destination. Charging and discharging are performed. In S5, the user moves the vehicle 2 to the designated battery recycling plant 5. In the case of a vehicle that can be moved by the automatic driving of the vehicle 2, the movements of S3 and S5 may be performed by the automatic driving.

Since the battery 21 registered for reuse arrives at the battery regeneration factory 5 according to the flow described above, the OCV of the battery 21 becomes a value close to the set value at the time of providing to the reuse destination when the battery 21 arrives at the battery regeneration factory 5. There is. Therefore, after removing the battery 21 from the vehicle body, it can be provided to the reuse destination without performing OCV adjustment, or a plurality of batteries can be connected without performing OCV adjustment.

<Processing example of server processing unit>
FIG. 3 is a flowchart showing a processing example of the processing unit 11 of the server 1, and shows the processing of the server 1 when the OCV adjustment method of FIG. 2 is performed. This processing example is realized, for example, by the processing unit 11 reading and executing the program stored in the storage unit 12. For example, the processing unit 11 executes this processing at predetermined intervals.

In S101, the processing unit 11 confirms whether or not the reuse registration has been accepted, and if so, proceeds to the process of S102, and if not, ends the current processing cycle. Specifically, the processing unit 11 confirms whether or not the reuse registration of the battery 21 has been accepted from the terminal 3 of the vehicle 2 or the user of the vehicle 2. Further, for example, when accepting the reuse registration, the processing unit 11 can acquire the user information, the vehicle 2 information, and the like together with the information to that effect.

In S102, the processing unit 11 acquires information on the electricity cost of the vehicle 2 equipped with the battery 21 registered for reuse, that is, the vehicle 2 in which the installed battery 21 is scheduled to be collected. For example, the processing unit 11 acquires information on the electricity cost of the vehicle 2 by communicating with the vehicle 2. For example, the information to be acquired includes the electricity cost (km / Wh) in the total mileage of the vehicle 2 and the electricity cost for the latest predetermined period (for example, one month). When the database DB of the server 1 manages the data related to the usage status of the vehicle 2, the processing unit 11 may acquire the information related to the electricity cost from the database DB. If there is a management server that manages data related to the usage status of the vehicle 2 in addition to the server 1, the processing unit 11 may acquire information on the electricity cost of the vehicle 2 from the management server.

In S103, the processing unit 11 acquires the position information of the vehicle 2. The processing unit 11 may acquire information on the storage location of the vehicle 2, such as the position information of the parking lot of the vehicle 2 and the address of the user, instead of the position information of the vehicle 2.

In S104, the processing unit 11 designates the charging station 4 and the collection location. Specifically, the processing unit 11 designates a charging station 4 that charges and discharges the battery 21 before the battery 21 is collected, and a battery regeneration factory 5 as a collection place of the battery 21. In one embodiment, the processing unit 11 has the shortest travel distance when moving from the current position of the vehicle 2 to the battery regeneration factory 5 via the charging station 4 based on the position information of the vehicle 2. The charging station 4 and the battery regeneration factory 5 are designated. Further, in one embodiment, the processing unit 11 designates the location closest to the current location of the vehicle 2 as the collection location among the battery regeneration factories 5 that can newly accept the battery 21 for reuse. It should be noted that, for example, a configuration in which the charging station 4 and the battery recycling factory 5 are specified on the user side at the time of reuse registration can be adopted.

In S105, the processing unit 11 sets a target value at the time of charging / discharging at the charging station 4. Specifically, the processing unit 11 at the charging station 4 is based on the information related to the electricity cost acquired in S102 and the distance between the charging station 4 specified in S104 and the battery recycling factory 5 as the collection place. Set the target value for charging and discharging.

For example, the processing unit 11 is a vehicle from the charging station 4 to the battery recycling plant 5 based on the electric energy (km / Wh) of the vehicle 2 and the distance (km) between the charging station 4 and the battery recycling plant 5 as a collection place. The power consumption (Wh) when 2 moves is estimated. Then, the processing unit 11 sets a target value at the time of charging / discharging at the charging station 4 so that the OCV value of the battery 21 becomes a predetermined value when the estimated power consumption amount of power is consumed. .. Examples of the predetermined value include an OCV setting value when the battery is provided to the reuse destination, a value determined when connecting a plurality of batteries 21, and the like.

In one embodiment, the target value set may be the charge / discharge amount [Ah]. In this case, the processing unit 11 may set the target value in consideration of the battery capacity [Ah] of the current battery 21 and the distance from the current position of the vehicle 2 to the charging station 4. By setting the set target value as the charge / discharge amount, the charging station 4 can charge / discharge according to the target value.

Further, in one embodiment, the target value to be set may be an OCV [V] or a value of SOC (State of Charge) [%] which is an index of the state of charge of the battery 21. By setting the target value to a value related to the state of the battery 21, it is possible to set a target value that does not depend on the current battery capacity of the battery 21, the distance from the current position of the vehicle 2 to the charging station 4, or the like. When the target value is an OCV or SOC value, for example, the charging station 4 calculates the discharge charge amount from the current value and the target value of the OCV or SOC, and executes charging / discharging of the battery 21.

The set target value can be associated with information such as an identification number of the vehicle 2 or the battery 21 or an identification number issued at the time of reuse registration, and information about the target value can be transmitted to the charging station 4. For example, the charging station 4 that has received the target value accepts the input of the identification number of the vehicle 2 or the battery 21 and the identification number issued at the time of reuse registration by the user or the like who has performed the reuse registration. Then, when the information received from the server 1 and the information input by the user or the like match, the charging station 4 may execute charging / discharging based on the target value at the time of charging / discharging.

Further, the set target value may be transmitted to the vehicle 2. Then, the vehicle 2 that has received the target value may request the charging station 4 to charge / discharge an amount corresponding to the target value when moving to the charging station 4.

In S106, the processing unit 11 gives an instruction to the user. For example, the processing unit 11 charges and discharges the vehicle 2 to the vehicle 2 or the user's terminal 3 at the charging station 4 designated in S104, and then moves the vehicle 2 to the battery recycling factory 5 as a designated collection place. Send an instruction to let you. FIG. 4 is a diagram showing a configuration example of a screen displayed on the display unit 23 or the display unit 34. The vehicle 2 that has received the instruction from the server 1 can display the screen 6 on the display unit 23. Further, the terminal 3 that has received the instruction from the server 1 can display the screen 6 on the display unit 34.

In addition, the processing unit 11 may also instruct the route from the charging station 4 to the battery regeneration factory 5. For example, when the display unit 23 or the display unit 34 is composed of a touch panel or the like, a button 6a for displaying a route is provided on the screen 6, and when the user touches the button 6a, the charging station 4 to the battery regeneration factory 5 Can be configured to display the route to. By moving the vehicle 2 from the charging station 4 to the battery regeneration factory 5 along the designated route, the OCV of the battery 21 at the time of arriving at the battery regeneration factory 5 can be adjusted more accurately. When the vehicle 2 is a vehicle that can be automatically moved to the battery regeneration factory 5, the server 1 may send a movement instruction to the battery regeneration factory 5 to the vehicle 2 instead of an instruction to the user. .. That is, the user does not necessarily have to recognize the collection location, and the server 1 may send an instruction so that the vehicle 2 can move to the battery regeneration factory 5 which is the collection location.

As described above, according to the present embodiment, the target value at the time of charging / discharging at the charging station 4 before collection is set based on the information on the electricity cost of the vehicle 2 and the distance between the charging station 4 and the battery recycling factory 5. Set. Therefore, when the vehicle 2 arrives at the battery regeneration factory 5 as the collection place, the OCV of the battery 21 becomes the adjusted value. Therefore, the OCV of the battery can be adjusted efficiently.

<Second Embodiment>

The storage unit 442 is, for example, a memory such as a RAM or a ROM, and stores data or the like used by the processing unit 441 for processing in addition to the program executed by the processing unit 441. The I / F unit 443 relays communication between the processing unit 441 and an external device such as the vehicle 2.

In the OCV adjustment method of the battery 21 by the system SY2, the user does not perform reuse registration or the like in advance before heading to the charging station 40, but the user faces the charging station 40 in the vehicle 2 and performs reuse registration at the charging station 40. The OCV adjustment of the battery 21 is started. That is, in the present embodiment, the charging station 40 also serves as a receptionist for reuse registration.

In S201, the processing unit 441 confirms whether or not the reuse registration has been accepted, and if so, proceeds to the process of S202, and if not, ends the current processing cycle. For example, the charging station 40 can accept reuse registration by the user of the vehicle 2 via the input unit 43, and the processing unit 441 confirms whether or not the reuse registration has been accepted by the input unit 43.

In S202, the processing unit 441 acquires information on the electricity cost of the vehicle 2 equipped with the battery 21 registered for reuse, that is, the vehicle 2 in which the installed battery 21 is scheduled to be collected. For example, the processing unit 441 acquires information on the electricity cost of the vehicle 2 by performing wired communication with the vehicle 2 or wireless communication such as Wi-Fi (registered trademark). For example, the information to be acquired includes the electricity cost (km / Wh) in the total mileage of the vehicle 2 and the electricity cost for the latest predetermined period (for example, one month).
