Description

Technical Field

[0001] The present disclosure relates to a navigation system and a vehicle equipped with the navigation system. Background Art

[0002] Japanese Patent Application Laid-Open No. 2021-009108 discloses a technology for guiding a vehicle equipped with a battery to a charging station where the battery can be charged. In this technology, the vehicle's battery functions as an energy storage device, and the charging station functions as an energy supply facility that supplies energy (electricity) to the battery. Summary of the Invention

[0003] In recent years, vehicles equipped with replaceable energy storage devices have become increasingly practical. In such vehicles, the vehicle's energy reserves can be increased by replacing the vehicle's onboard energy storage device with another device that stores more energy than the original. Furthermore, such vehicles may receive energy from energy supply facilities. Therefore, when recharging such vehicles, guiding them not only to a replacement location for the energy storage device but also to a supply location with an energy supply facility may improve user convenience. However, when recharging such vehicles, guiding them to a supply location may not always improve user convenience. For example, the vehicle may not be equipped to receive energy from the energy supply facility. Furthermore, the energy supply facilities located near the vehicle may be frequently used, resulting in longer wait times for users to access them. Furthermore, the performance of the energy supply facilities located near the vehicle may be low, and it may take a long time for the energy storage device to be fully supplied with energy. In these situations, guiding the vehicle to a supply location may actually reduce user convenience. Thus, there is still room for improvement in the technology for guiding vehicles equipped with energy storage devices.

[0004] The present disclosure provides a navigation system capable of improving the convenience for a user of a vehicle equipped with an energy storage device that is attachable and detachable by a replacement device, and a vehicle equipped with the navigation system.

[0005] A first aspect of the present disclosure relates to a navigation system including a guidance device.

[0006] The navigation system of the first aspect of the present disclosure is configured to guide a vehicle equipped with a removable energy storage device. The navigation system includes a guidance device configured to present information for guiding the vehicle to at least one of a replacement location and a supply location. The replacement location is a location where the energy storage device is replaced. The supply location is a location where energy supply equipment for supplying energy to the energy storage device is installed. The guidance device is configured to guide the vehicle to the supply location if predetermined conditions are met, and not to guide the vehicle to the supply location if the predetermined conditions are not met.

[0007] According to the navigation system of the first aspect, the vehicle is guided to the supply point only when predetermined conditions (hereinafter referred to as "guidance conditions") are met. By ignoring the guidance conditions in anticipation of a reduction in user convenience when guiding the vehicle to the supply point, the reduction in user convenience can be minimized. Furthermore, by guiding the vehicle to the supply point when the guidance conditions are met, user convenience can be enhanced.

[0008] In addition, the energy storage device can be either a power storage device in a BEV (electric vehicle), HEV (hybrid electric vehicle) or PHEV (plug-in hybrid electric vehicle), or a hydrogen tank in an FCEV (fuel cell vehicle).

[0009] In the navigation system of the first aspect of the present disclosure, the guidance device may be configured to determine whether the vehicle has a first device for receiving energy supplied from the energy supply facility to the energy storage device. The predetermined condition (guidance condition) may include whether the vehicle has the first device.

[0010] In the navigation system configured as described above, if the vehicle does not have the first equipment (equipment for receiving energy supplied from the energy supply facility to the energy storage device), the vehicle will not be guided to the supply location. Therefore, if the vehicle cannot use the energy supply facility, the vehicle will not be guided to the supply location. This minimizes the reduction in user convenience.

[0011] In the navigation system configured as described above, the guidance device may be configured to present first information indicating that the vehicle is guided to a replacement location and not to a supply location if a predetermined condition (guidance condition) is not satisfied. Furthermore, the guidance device may be configured to present either second information indicating that the vehicle is guided to both a replacement location and a supply location, or third information indicating that the vehicle is guided to a supply location and not to a replacement location if the predetermined condition (guidance condition) is satisfied.

[0012] According to the navigation system configured as described above, it is easy to perform appropriate guidance according to whether the guidance conditions are met.

[0013] In the navigation system configured as described above, the guidance device may be configured to determine whether an abnormality has occurred in a second device used to load or unload the energy storage device in the vehicle. Furthermore, the guidance device may be configured to present a third message if it is determined that the vehicle has the first device and that an abnormality has occurred in the second device.

[0014] According to the navigation system configured as described above, if an abnormality occurs in the second equipment of a vehicle (equipment used to load or unload an energy storage device), the vehicle is not guided to a replacement location but to a supply location. Therefore, if the energy storage device cannot be loaded or unloaded, the vehicle is not guided to a replacement location. This minimizes the reduction in user convenience. Furthermore, in this case, the vehicle is guided to a supply location, thereby improving user convenience.

[0015] The navigation system configured as described above may further include a search device configured to search for a replacement location within a predetermined area. The guidance device may also be configured to obtain inventory information indicating the inventory status of replacement energy storage devices that can be installed in the vehicle instead of the energy storage device, for replacement locations found through the search within the predetermined area, and use this inventory information to determine whether the replacement location has a replacement energy storage device. Furthermore, the guidance device may be configured to present a third information if it is determined that the vehicle has the first equipment and there is no replacement location with a replacement energy storage device within the predetermined area.

[0016] According to the navigation system configured as described above, if there is no replacement location with a replacement energy storage device in a predetermined area, the vehicle is guided to a supply location instead of to the replacement location. This prevents the vehicle from being guided to a replacement location that does not have a replacement energy storage device in stock.

[0017] In the navigation system configured as described above, the energy storage device and the replacement energy storage device may each be a power storage device configured to be attachable and detachable via a replacement device. The replacement location may also be a location where a replacement device is located. The guidance device may also be configured to, upon determining that a replacement location with a replacement energy storage device exists within a predetermined area, use inventory information to determine as a guidance target a replacement location with a replacement energy storage device that meets predetermined requirements. Furthermore, the predetermined requirements may be determined regarding at least one of the power storage device's storage capacity, maximum output power, maximum regenerative power, and capacity.

[0018] According to the navigation system configured as described above, it is easy to set the necessary conditions (such as the status or specifications) that are optimal for the vehicle regarding the replacement energy storage device.

[0019] In the navigation system constructed as described above, the guidance device may also include a display device that displays information to the user of the vehicle. The first information may be prompted so that the display device displays the change location on the map without displaying the supply location, or the display device displays the change location and the supply location separately on the map in a recognizable format. The second information may be prompted so that the display device displays the change location and the supply location on the map, or the display device displays the change location and the supply location separately on the map in a recognizable format. Furthermore, the third information may be prompted so that the display device displays the supply location on the map without displaying the change location, or the display device displays the change location and the supply location separately on the map in a recognizable format. In the navigation system constructed as described above, the guidance device may also include a speaker in addition to the display device.

[0020] According to the navigation system configured as described above, by displaying one of the replacement and supply locations on a map, or by displaying both the replacement and supply locations in a recognizable format on a map, the vehicle can be appropriately guided. If the guidance device includes a speaker in addition to the display device, the vehicle can be appropriately guided by voice guidance in addition to the above display. If the guidance device includes a speaker in addition to the display device, the vehicle can be appropriately guided by voice guidance in addition to the above display.

[0021] In the navigation system of the first aspect of the present disclosure, the guidance device may be configured to determine a guidance destination including at least one of a replacement location and a supply location when the energy storage level of an energy storage device mounted on the vehicle decreases below a reference value. Furthermore, the guidance device may be configured to guide the vehicle to the guidance destination.

[0022] According to the navigation system configured as described above, a guidance destination is determined when the vehicle's energy reserve is low, and the vehicle is guided to the guidance destination. By determining a guidance destination when the vehicle needs energy replenishment, it is easy to determine a guidance destination that is optimal for the vehicle.

[0023] The navigation system of the first aspect of the present disclosure may further include an input device for receiving a guidance request from a user. The guidance device may be configured to determine a guidance destination, including at least one of a replacement location and a supply location, upon receiving the guidance request. Furthermore, the guidance device may be configured to guide the vehicle to the guidance destination.

[0024] According to the navigation system configured as described above, a guidance destination is determined based on a request from a user, and the vehicle is guided to the guidance destination. By determining a guidance destination at the timing of the user's guidance request, it is easy to determine a guidance destination that is preferred by the user.

[0025] The navigation system of the first aspect of the present disclosure may further include a search device configured to search for replacement locations within a predetermined area. The guidance device may also be configured to, when at least one replacement location is selected as a guidance target, obtain inventory information indicating the inventory status of replacement energy storage devices that can be installed in the vehicle instead of the energy storage device for each candidate guidance target found by searching within the predetermined area. Furthermore, the guidance device may be configured to use the inventory information to determine a guidance target and guide the vehicle to the guidance target.

[0026] The navigation system configured as described above makes it easy to select a replacement location with a replacement energy storage device that can be installed in a vehicle from among multiple replacement locations (candidates for guidance) located in a predetermined area and determine it as the guidance destination. This improves user convenience. Furthermore, it prevents the vehicle from being guided to a replacement location that does not have a replacement energy storage device. This minimizes a reduction in user convenience.

[0027] In the navigation system configured as described above, the guidance device may include a display device configured to display information to a vehicle user and a control device configured to control the display device. If the vehicle is equipped with multiple energy storage devices, the control device may be configured to categorize the guidance destination into either a first replacement location capable of replacing the inventory status of all of the vehicle's multiple energy storage devices or a second replacement location capable of replacing the inventory status of only a portion of the vehicle's multiple energy storage devices. Furthermore, the display device may be configured to display the first and second replacement locations in a manner that allows the user to distinguish between the two.

[0028] According to the navigation system configured as described above, the display device displays the first and second change locations in a manner that allows the user to distinguish between them. The user can select which of the first and second change locations to use, thereby improving user convenience.

[0029] A second aspect of the present disclosure relates to a vehicle.

[0030] The vehicle of the second embodiment of the present disclosure includes a navigation system configured to guide the vehicle and a power storage device as a detachable energy storage device. The vehicle is configured to be able to travel using the power output from the power storage device. The navigation system includes a guidance device configured to provide information for guiding the vehicle to at least one of a replacement base and a supply base. The replacement base is a base for replacing the energy storage device. The supply base is a base where energy supply equipment for supplying energy to the energy storage device is installed. Moreover, the guidance device is configured to guide the vehicle to the supply base when a predetermined condition is met, and not to guide the vehicle to the supply base when the predetermined condition is not met.

[0031] According to the second aspect of the present disclosure, the vehicle includes the aforementioned navigation system, thereby providing the advantages of the aforementioned navigation system and improving user convenience.

[0032] A third aspect of the present disclosure relates to a navigation system including a guidance device.

[0033] A navigation system according to a third aspect of the present disclosure is configured to guide a vehicle equipped with an energy storage device. The navigation system includes a guidance device configured to present information for guiding the vehicle to at least one of a replacement location and a supply location. A replacement location is a location where an energy storage device is replaced. A supply location is a location where energy supply equipment for supplying energy to the energy storage device is installed. The guidance device is configured to guide the vehicle to the replacement location if predetermined conditions are met, and not to guide the vehicle to the replacement location if the predetermined conditions are not met.

[0034] The navigation system according to the third aspect of the present disclosure can also improve user convenience.

[0035] A fourth aspect of the present disclosure relates to a vehicle.

[0036] The vehicle of the fourth embodiment of the present disclosure includes a navigation system configured to guide the vehicle and a power storage device serving as an energy storage device. The vehicle is configured to be able to travel using the power output from the power storage device. The navigation system includes a guidance device configured to provide information for guiding the vehicle to at least one of a replacement base and a supply base.

[0060] The embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and their description will not be repeated.

[0061] The vehicle involved in this embodiment includes a vehicle body and a battery pack. The vehicle body is the portion of the vehicle other than the battery pack. In the vehicle involved in this embodiment, a charging device (first device) for receiving power supply (energy supply) from an EVSE (Electric Vehicle Supply Equipment: vehicle power supply equipment) to a battery pack is optional. On the other hand, in this vehicle, a replacement device (second device) for loading and unloading a battery pack in the vehicle is installed as standard equipment. That is, when purchasing a vehicle, the user can choose whether to add a charging device to the vehicle. In addition, the user can also add a charging device later after purchasing the vehicle. Here, the "battery pack" is an example of an "energy storage device" disclosed in the present invention.

[0062] Figure 1 1 is a diagram showing the configuration of a vehicle 100A to which charging equipment (optional equipment) is added. Figure 1 Vehicle 100A includes a vehicle body 10A and a battery pack 20. Vehicle 100A is configured to travel using the power output from battery pack 20. Vehicle 100A is, for example, an electric vehicle (BEV) without an internal combustion engine. However, this is not limiting and vehicle 100A may be a PHEV (plug-in hybrid electric vehicle) with an internal combustion engine or another electric vehicle (xEV).

[0063] Vehicle body 10A includes circuits CR11A and CR12. Battery pack 20 includes circuits CR21 and CR22. Circuit CR12 includes auxiliary battery 17. Circuit CR21 includes battery 21. Auxiliary battery 17 functions as a low-voltage power source that outputs power at a voltage lower than that of battery 21. Circuit CR21 applies the voltage (high voltage) supplied by battery 21 to circuit CR11A. Circuit CR11A receives the voltage (high voltage) from battery 21. Circuit CR12 applies the voltage (low voltage) supplied by auxiliary battery 17 to circuit CR22. Circuit CR22 receives the voltage (low voltage) from auxiliary battery 17. A DC / DC converter 16 is provided between circuits CR11A and CR12.

[0064] Circuit CR11A within vehicle body 10A includes a motor generator (MG) 11a, an inverter 11b, a DC charging relay 14a, a DC charging inlet 14b, an AC charger 15a, and an AC charging inlet 15b. Circuit CR11A is equipped with a leakage detector 12. Circuit CR21 within battery pack 20 includes a battery management system (BMS) 22a and a leakage detector 22b. Vehicle body 10A also includes a terminal T11, from which the battery pack 20 can be attached and removed, and an SMR 13, located between terminal T11 and circuit CR11A. Circuit CR11A (high-voltage power line) is connected to terminal T11 via SMR 13. Battery pack 20 also includes a terminal T21, from which the battery pack 20 can be attached and removed from vehicle body 10A, and an SMR 23, located between terminal T21 and circuit CR21. Circuit CR21 (high-voltage power line) is connected to terminal T21 via SMR 23. "SMR" means System Main Relay.

[0065] The battery 21 is a secondary battery such as a lithium-ion battery, a nickel-metal hydride battery, or a sodium-ion battery. The secondary battery can be either a liquid secondary battery or an all-solid secondary battery. A plurality of secondary batteries can also form a battery pack.

[0066] The vehicle body 10A further includes a terminal T12. The circuit CR12 (low voltage power line) in the vehicle body 10A is connected to the terminal T12. In addition, the communication line CL1 ( Figure 1 The battery pack 20 also has a terminal T22. The circuit CR22 (low voltage power line) in the battery pack 20 is connected to the terminal T22. The communication line CL2 ( Figure 1 The dotted line in FIG) is also connected to terminal T22.

[0067] Auxiliary battery 17 supplies power for driving auxiliary equipment mounted on vehicle 100A. Auxiliary battery 17 outputs DC power to circuit CR12. Circuit CR12 includes ECUs 18a, 18b, 18c, and 18d in addition to auxiliary battery 17. Circuit CR22 also includes ECUs 28a and 28b. Auxiliary battery 17 supplies power to ECUs 18a through 18d, and 28a and 28b, connected to a low-voltage power line, for example. "ECU" stands for Electronic Control Unit.

[0068] ECU 18a corresponds to the control device (EV-ECU) that oversees various controls related to vehicle 100A. ECU 18b corresponds to the control device (Plg-ECU) that detects the status of the DC charging inlet 14b and the AC charging inlet 15b. Each of the DC charging inlet 14b and the AC charging inlet 15b has a terminal that detects whether a charging cable (charging plug) is connected and outputs a signal indicating whether a charging cable is connected to ECU 18b. ECU 18c corresponds to the control device (Bat-C-ECU) that controls the DC charging relay 14a and the AC charger 15a. ECU 18d corresponds to the control device (first leakage ECU) that monitors the leakage status of circuit CR11A. ECU 28a corresponds to the control device (Bat-ECU) that monitors the status of battery 21 and controls SMR 23. ECU 28b corresponds to the control device (second leakage ECU) that monitors the leakage status of circuit CR21.

[0069] Each ECU includes a processor and a storage device. The storage device is configured to store information. In addition to programs, the storage device also stores various information used by the programs. In this embodiment, the processor executes the programs stored in the storage device to perform various controls. However, these processes can also be performed solely by hardware (electronic circuitry) without using software.

[0070] In vehicle 100A, the ECUs are interconnected and communicative via an in-vehicle network. An example of the in-vehicle network is a CAN (Controller Area Network). ECU 18a receives information from other ECUs to control inverter 11b, DC / DC converter 16, and SMR 13, and sends control commands to ECU 18c and ECU 28a.

[0071] The leakage detector 12 detects the leakage state (e.g., insulation resistance) associated with circuit CR11A and outputs the detected leakage state to ECU 18d. The BMS 22a detects the state of battery 21 (current, voltage, temperature, SOC, capacity, etc.) and outputs the detection results to ECU 28a. The SOC (State of Charge) indicates the remaining charge, for example, expressing the ratio of the current charge to the charge at a fully charged state on a scale of 0 to 100%. The battery capacity corresponds to the amount of charge (kWh) stored in the battery at a fully charged state. The leakage detector 22b detects the leakage state (e.g., insulation resistance) associated with circuit CR21 and outputs the detected leakage state to ECU 28b. ECU 18a obtains information indicating the battery state and leakage state from ECUs 18d, 28a, and 28b.

[0072] The DC / DC converter 16 transforms DC power between circuit CR11A and circuit CR12. Specifically, the DC / DC converter 16 steps down the DC power from the battery 21 and outputs the low-voltage DC power to the auxiliary battery 17. The ECU 18a can also control the DC / DC converter 16 so that when the remaining charge in the auxiliary battery 17 decreases, power is supplied from the battery 21 (main battery) to the auxiliary battery 17. The capacity of the battery 21 is greater than that of the auxiliary battery 17. Furthermore, the SMRs 13 and 23 each switch between connecting and disconnecting the circuits CR11A and CR21. When the battery 21 voltage is applied to circuit CR11A, the ECU 18a closes both SMRs 13 and 23 (connected). When the battery 21 voltage is not applied to circuit CR11A, the ECU 18a opens at least one of the SMRs 13 and 23 (disconnected).

[0073] Terminals T21 and T22 of the battery pack 20 are configured to be removable from terminals T11 and T12 of the vehicle body 10A, respectively. By connecting terminals T21 and T22 to terminals T11 and T12, the battery pack 20 is mounted on the vehicle body 10A, completing the vehicle 100A. In vehicle 100A, circuit CR11A within the vehicle body 10A is connected to circuit CR21 within the battery pack 20 via SMRs 13 and 23. Furthermore, circuit CR12 within the vehicle body 10A is connected to circuit CR22 within the battery pack 20. Communication lines CL1 and CL2 are also interconnected. These communication lines constitute the in-vehicle network.

[0074] The MG 11a functions as a motor for driving. The inverter 11b functions as a PCU (Power Control Unit) for the MG 11a. The inverter 11b drives the MG 11a using power supplied from the battery 21. The MG 11a converts the power into torque, rotating the drive wheels of the vehicle 100A. Furthermore, when the vehicle 100A is decelerating, for example, the MG 11a generates regenerative power to charge the battery 21.

[0075] The vehicle body 10A further includes an HMI (Human Machine Interface) 19a and a communication device 19b. The HMI 19a and the communication device 19b also receive power from the auxiliary equipment battery 17. The HMI 19a includes an input device and a display device mounted on the vehicle body 10A. The communication device 19b is configured to be able to communicate with the mobile terminal 200 and the server 380 (described later). Figure 3) for wireless communication. Mobile terminal 200 corresponds to a portable terminal that can be carried by a user. For example, mobile terminal 200 is a smartphone equipped with a touch panel display. However, mobile terminal 200 is not limited thereto; laptop computers, portable game consoles, wearable devices, electronic keys, and the like can also be used as mobile terminal 200.

[0076] The vehicle body 10A is also equipped with various sensors (onboard sensors 19c), not shown. These sensors 19c may include sensors that detect the status (current, voltage, temperature, etc.) of the auxiliary equipment battery 17, sensors that detect charging power (charging voltage and charging current), sensors that detect the input and output power of the inverter 11b, and sensors that detect whether the battery pack 20 is connected and / or fixed to the vehicle body 10A. The ECU 18a is configured to obtain the detection results of these sensors directly or through other ECUs.

[0077] Figure 2 1 is a diagram showing the configuration of a vehicle 100B without adding charging equipment (optional equipment). Figure 2 The vehicle 100B includes a vehicle body 10B and a battery pack 20. The vehicle 100B has Figure 1 The vehicle 100A shown in the figure is a structure in which the DC charging relay 14a, the DC charging socket 14b, the AC charger 15a and the AC charging socket 15b are removed. The vehicle body 10B includes a circuit CR11B. The circuit CR11B includes a vehicle drive device (MG11a and inverter 11b), but does not include charging equipment (DC charging relay 14a, DC charging socket 14b, AC charger 15a and AC charging socket 15b). The vehicle 100B is configured to be able to use the power stored in the battery pack 20 to travel by having a vehicle drive device. The vehicle 100A and the vehicle 100B have a common control system. The vehicle body 10B involved in this embodiment is provided with ECUs 18b and 18c, similar to the vehicle body 10A. This makes it easy to install charging equipment later. However, it is also possible to start from Figure 2 The illustrated structure of the vehicle body 10B omits the ECUs 18b and 18c.

[0078] Vehicles 100A and 100B each include replacement equipment for attaching and detaching a replaceable battery pack 20. The battery packs (battery packs 20) mounted on each vehicle 100A and 100B can be replaced with other battery packs. Hereinafter, unless otherwise specified, vehicles 100A and 100B are each referred to as "vehicle 100," and vehicle bodies 10A and 10B are each referred to as "vehicle body 10."

[0079] Figure 3 This is a diagram showing an example of the configuration of a battery replacement system for replacing a battery pack. Figure 3The battery replacement system 300 shown is installed, for example, at a battery replacement station. Figure 3 The battery replacement system 300 is configured to remove the battery pack mounted on the vehicle 100 from the vehicle body 10 and install another battery pack on the vehicle body 10. Hereinafter, the battery pack (first power storage device) recovered from the vehicle 100 will be referred to as "battery pack B1". In addition, the battery pack (second power storage device) installed on the vehicle 100 instead of the battery pack B1 will be referred to as "battery pack B2". The battery pack B2 is equivalent to a replacement battery pack (replacement energy storage device) that can be installed on the vehicle 100 instead of the battery pack B1. The battery packs B1 and B2 each have the same Figure 1 、 Figure 2 The battery pack B2 mounted on the vehicle body 10 serves as the battery pack 20 ( Figure 1 、 Figure 2 ) to perform its function.

[0080] The battery replacement system 300 involved in this embodiment includes a first storage device 310, a second storage device 320, a collection device 330, a filling device 340, a replacement device 350, a server 380, and a display device 390. The first storage device 310 stores multiple battery packs supplied to vehicles. In addition to a pack storage unit (such as a storage warehouse), the first storage device 310 also includes a charger and a supply device. The second storage device 320 stores multiple battery packs collected from multiple vehicles. In addition to a pack storage unit (such as a storage warehouse), the second storage device 320 also includes an inspection device and a sorting device. The server 380 includes a processor, a storage device, and a communication device. The storage device stores information related to each battery pack present in the battery replacement system 300, distinguishing them by their identification information. The display device 390 displays information according to instructions from the server 380.

[0081] Figure 4 350 is a diagram showing an example of a replacement device 350. Figure 4The replacement device 350 is configured to replace a battery pack mounted on a vehicle body with another battery pack. Specifically, the replacement device 350 includes a vehicle body retaining portion 351, a battery retaining portion 352, a battery adjustment portion 353, and a battery fixing portion 354. The battery retaining portion 352 includes a plate-shaped member, positioning pins 352a provided on the plate-shaped member, and a conveying portion 352b. The conveying portion 352b may include rollers capable of rising, falling, and rotating, for example. The battery adjustment portion 353 is configured to adjust the position and angle of the battery pack held in the battery retaining portion 352 by changing the position and angle of positioning members (e.g., L-shaped blocks located at the corners of the battery pack). The battery fixing portion 354 is connected to the battery retaining portion 352. The battery fixing portion 354 is configured to secure the battery pack held in the battery retaining portion 352 to the vehicle body, or to release the battery pack from the vehicle body using an electric tool. The battery fixing portion 354 may also include an electric tool for tightening or loosening screws. Although not shown in the drawings, the replacement device 350 further includes an actuator (eg, a motor) for driving each component.

[0082] The replacement device 350 replaces the battery pack of the vehicle 100 by, for example, the following process. Before the replacement operation starts, the replacement device 350 becomes Figure 4 State A shown. That is, the vehicle body holding portion 351 and the battery holding portion 352 are located below the vehicle 100. The replacement device 350 may also use various sensors and / or cameras to detect the position of the vehicle 100. When the replacement device 350 receives the battery pack removal instruction from the server 380, the vehicle body holding portion 351 and the battery holding portion 352 rise toward the vehicle 100, and the replacement device 350 becomes Figure 4 State B shown. Although omitted in the figure, in state B, the battery adjustment part 353 also rises to the same height as the battery holding part 352. In state B, the vehicle body 10 is held by the vehicle body holding part 351. The vehicle body holding part 351 can also lift the vehicle body 10 to a state in which the vehicle body 10 is floated and hold it. On the other hand, the battery pack 20 (battery pack B1) is held by the battery holding part 352. At this time, the positioning pin 352a is inserted into the hole provided on the bottom surface of the battery pack 20. As a result, the battery pack 20 and the battery holding part 352 (and the battery fixing part 354) are in a predetermined positional relationship. In addition, the battery fixing part 354 releases the fixation (for example, screw connection) between the vehicle body 10 and the battery pack 20. As a result, the vehicle body 10 and the battery pack 20 can be separated. After the fixation is released, the battery holding part 352 descends away from the vehicle body 10 while holding the battery pack 20 as it is, and the replacement device 350 becomes Figure 4The battery pack 20 is thus removed from the vehicle body 10. Although not shown, in state C, the battery adjustment unit 353 also descends to the same height as the battery holding unit 352. Next, the conveying unit 352b separates the battery pack 20 held in the battery holding unit 352 from the positioning pin 352a, and conveys the battery pack 20 to the collection device 330 ( Figure 3 ).

[0083] Then, according to the battery pack installation instruction from the server 380, the first storage device 310 ( Figure 3 ) The battery pack 20 (battery pack B2) is supplied to the battery holder 352. The battery adjuster 353 adjusts the position and angle of the battery pack 20, inserting the positioning pin 352a into the hole provided on the bottom surface of the battery pack 20. Next, the battery holder 352, still holding the battery pack 20, rises toward the vehicle body 10, and the replacement device 350 returns to state B. As a result, the battery pack 20 held in the battery holder 352 is mounted on the vehicle body 10. When the replacement device 350 receives a battery pack securing instruction from the server 380, the battery securing unit 354 secures (e.g., with screws) the battery pack 20 held in the battery holder 352 to the vehicle body 10. After securing is complete, the vehicle holder 351 and the battery holder 352 descend away from the vehicle body 10, and the replacement device 350 returns to state A. The replacement operation is thus completed. At this point, the display device 390 may indicate that the replacement operation is complete. The above-described replacement device structure and replacement operation process are merely examples and may be modified as appropriate. Automation of the replacement process is not essential. Users can also manually replace the replaceable battery pack (power storage device).

[0084] Regarding the removed battery pack B1, the recycling process is executed. Specifically, Figure 3 As shown, the recovery device 330 transports (recovers) the battery pack B1 from the replacement device 350 to the second storage device 320. Furthermore, the multiple battery packs stored in the second storage device 320 are inspected sequentially by the inspection device, and the selection device selects these battery packs for each use based on the inspection results. Each battery pack is reused for the corresponding use (on-vehicle use, stationary use, etc.). However, battery packs that cannot be directly reused are disassembled and recycled as materials or discarded. The battery packs (for on-vehicle use) reused in the battery replacement system 300 are transported to the first storage device 310 by the filling device 340. The transported battery packs are filled in the first storage device 310.

[0085] exist Figure 3, an example of removing the battery pack and installing the battery pack at different positions is shown. The position of the vehicle can also be adjusted before removing the battery pack, before installing the battery pack (after removing the battery pack), or both before and after removing the battery pack. The vehicle can also be moved by a conveying device (such as a conveying device using a conveyor belt) or a conveying robot not shown in the figure. However, the battery pack can also be removed and installed at the same position. The battery pack can also be replaced (removed and installed) while the vehicle is stationary. The conveying method of each of the recovery device 330, the supply device, and the filling device 340 is also arbitrary. These conveying methods can be either a conveyor belt method or a method using a conveying robot.

[0086] In this embodiment, the vehicle 100A ( Figure 1 ) have replacement equipment (e.g. can use Figure 4 The replacement device 350 shown is a vehicle-mounted device for loading and unloading the battery pack 20 and a charging device (e.g. Figure 1 The DC charging relay 14a, DC charging socket 14b, AC charger 15a and AC charging socket 15b shown in the figure). Therefore, the vehicle 100A can use both the replacement base and the supply base. On the other hand, the vehicle 100B ( Figure 2 ) has replacement equipment but no charging equipment. Therefore, vehicle 100B can use the replacement equipment but cannot use the supply base. A replacement base is a location (location) where the battery pack is replaced. For example, a replacement base is a location where the replacement equipment 350 is installed (such as a battery replacement station). A supply base is a location where an EVSE is installed (such as a charging station).

[0087] Figure 5 This is a diagram used to explain the replacement and supply locations. Figure 5 , each of the replacement points P1-1, P1-2, P1-3, P1-4, P1-5, ... is equipped with Figure 3 The battery swap system 300 shown (including a swapping device 350) has a DC-EVSE 400A installed at each of the supply locations P2A-1, P2A-2, ..., that outputs DC power. An AC-EVSE 400B is installed at each of the supply locations P2B-1, P2B-2, P2B-3, ..., that outputs AC power. Each EVSE is connected to an external power source (e.g., a power grid) (not shown).

[0088] The replacement sites P1-1 and P1-2 are used by the vehicle 100A and the vehicle 100B, respectively. Figure 3 as well as Figure 4 ) Replace the battery pack.

[0089] The supply base P2A-2 is used by the vehicle 100A. Specifically, in the vehicle 100A, Figure 1 The ECUs 18a to 18c shown collaborate to perform charging control. ECU 18a obtains information indicating the status (connected / disconnected) of the DC charging inlet 14b from ECU 18b and sends control commands to ECU 18c. The DC charging inlet 14b is connected to the DC-EVSE 400A, for example, via a charging cable, and receives DC power from the DC-EVSE 400A (external to the vehicle). The DC power input from the DC-EVSE 400A to the DC charging inlet 14b charges the batteries 21 within the battery pack 20. At this time, ECU 18a closes the SMRs 13 and 23 (connected), and ECU 18c closes the DC charging relay 14a (connected). After charging is complete, ECU 18c opens the DC charging relay 14a (disconnected).

[0090] The supply base P2B-3 is used by the vehicle 100A. Specifically, in the vehicle 100A, Figure 1 The ECUs 18a to 18c shown collaborate to perform charging control. ECU 18a obtains information indicating the status (connected / disconnected) of the AC charging inlet 15b from ECU 18b and sends control commands to ECU 18c. The AC charging inlet 15b is connected to the AC-EVSE 400B via a charging cable, for example, and receives AC power from the AC-EVSE 400B (external to the vehicle). The AC charger 15a performs AC / DC conversion. When both SMRs 13 and 23 are closed (connected) and AC power is being input to the AC charger 15a from the outside of the vehicle via the AC charging inlet 15b, ECU 18c controls the AC charger 15a. Following the control commands from ECU 18c, the AC charger 15a converts the AC power into DC power and outputs the DC power to the battery 21 within the battery pack 20. This charges the battery 21. After charging is complete, ECU 18c shuts off the power (charging power) supplied by the AC charger 15a.

[0091] However, when recharging the energy of the vehicle 100A or 100B, it may be possible to improve the convenience of the user by guiding the vehicle (vehicle 100A or 100B) to the above-mentioned replacement location or supply location. Figure 5 The position P shown AIf the energy storage capacity of the vehicle 100A (e.g., the amount of energy stored in the battery pack 20) is low, it is considered to guide the vehicle 100A to the replacement base P1-5, the supply base P2A-1, and the supply base P2B-1. This makes it easier for the vehicle 100A to receive energy replenishment provided by the replacement device 350, the DC-EVSE 400A, or the AC-EVSE 400B, thereby improving the convenience of the user of the vehicle 100A. Figure 5 The position P shown B If the energy storage capacity of vehicle 100B decreases, it is considered to guide vehicle 100B to the replacement base P1-3, supply base P2A-1, and supply base P2B-2. However, vehicle 100B does not have equipment for receiving power supply from DC-EVSE 400A and AC-EVSE 400B to battery pack 20. Therefore, when vehicle 100B is guided to supply bases P2A-1 and P2B-2, there is a possibility that the convenience of the user of vehicle 100B will be impaired. Therefore, the vehicle 100 (vehicles 100A, 100B) involved in this embodiment has Figure 6 Navigation system 500 is shown. Figure 6 It is a diagram for explaining the configuration and operation of a navigation system 500 according to this embodiment.

[0092] Reference Figure 6 In this embodiment, the navigation system 500 is included in the vehicle 100A ( Figure 1 ) and vehicle 100B ( Figure 2 The navigation system 500 includes a control device 510 , a storage device 520 , a reporting device 530 , an input device 540 , a position detector 550 , and a wireless communication device 560 .

[0093] Control device 510 includes, for example, a processor 511, such as a CPU (Central Processing Unit), and a RAM (Random Access Memory) 512 for temporarily storing data. Storage device 520 pre-stores a control program and map information. The map information includes information (e.g., location information and specifications) regarding multiple replacement locations and multiple supply locations. Processor 511 executes the program stored in storage device 520, executing process flow F1, described below. However, process flow F1 can also be performed solely by hardware (electronic circuitry) rather than software.

[0094] Reporting device 530 includes a display 531 and a speaker 532. Display 531 is, for example, a touch panel display. Display 531 may also include an instrument panel or a heads-up display. Display 531 may also change its display orientation in response to instructions from control device 510. Display 531 may also display content based on XR technologies (techniques that combine real physical space with virtual space), such as VR (virtual reality) or AR (augmented reality). Speaker 532 may also include a buzzer.

[0095] Input device 540 outputs a signal corresponding to the user's input to control device 510. Input device 540 may also include an intelligent microphone that accepts voice input. Input device 540 may also include an identification device that identifies the user's status. The identification device may also include a camera that captures images from within the vehicle. When the identification device recognizes a predetermined signature input by the user (e.g., a handwritten signature such as a V signature), a signal corresponding to the recognized signature may be output from input device 540 to control device 510. With such an identification device, the user can send a prompt to input device 540 using their hand, etc., to make a predetermined request to control device 510.

[0096] Position detector 550 may be a sensor that uses a positioning system such as a GPS (Global Positioning System) to detect the current position (e.g., longitude and latitude) of vehicle 100. Alternatively, position detector 550 may use a gyroscopic sensor (not shown) that detects the rotation (orientation) of vehicle 100 to calculate the position of vehicle 100.

[0097] Wireless communication device 560 is a communication device capable of wireless communication with the outside of the vehicle. Control device 510 can also access a communication network via wireless communication device 560 to obtain arbitrary information (eg, the latest map information) from a data center (not shown) within the communication network.

[0098] The control device 510 executes Figure 6 Processing flow F1 (S101-S106) in the following. Hereinafter, the vehicle equipped with navigation system 500 (vehicle 100A or 100B) is referred to as the "target vehicle." Regardless of whether the target vehicle is vehicle 100A or 100B, control device 510 of navigation system 500 installed in the target vehicle executes processing flow F1. For example, processing flow F1 begins after navigation system 500 is started.

[0099] In S101, the control device 510 determines whether the charge level (e.g., SOC) of the battery 21 within the battery pack 20 has fallen below a predetermined reference value. The control device 510 may also obtain detection results from the BMS 22a within the battery pack 20 from the ECU 18a. While the charge level of the battery 21 is above the reference value ("No" in S101), the determination in S101 is repeated. Furthermore, if the charge level of the battery 21 falls below the reference value ("Yes" in S101), the control device 510 controls the notification device 530 in S102 to cause it to perform notification processing for the user. For example, the control device 510 displays a screen Sc1 on the display 531 (touch panel display). Screen Sc1 displays operation components M3 and M4, a message M1 indicating that the charge level of the battery pack 20 (battery 21) has decreased, and a message M2 urging the user to select whether to request guidance from the navigation system 500. The operation component M3 receives guidance requests from the user. The display 531 functions as both a display device and an input device.

[0100] In the following S103, the control device 510 determines whether the display 531 has received a guidance request. Specifically, if the user has operated the operating unit M3, the display 531 is determined to have received a guidance request ("Yes" in S103), and the process proceeds to S104. If the user has operated the operating unit M4, the display 531 is determined not to have received a guidance request ("No" in S103), and the process returns to the initial step (S101). Alternatively, the input device 540 may receive a guidance request from the user, in place of or in addition to the display 531.

[0101] In S104, the control device 510 determines whether the target vehicle has charging equipment (equipment for receiving power supplied to the battery pack 20 from an EVSE external to the vehicle). For example, the control device 510 may obtain information indicating whether the target vehicle has charging equipment from the ECU 18a. The ECU 18a may also determine whether the target vehicle has charging equipment based on information obtained from at least one of the ECUs 18b and 18c (particularly information regarding the DC charging relay 14a, the DC charging inlet 14b, the AC charger 15a, and the AC charging inlet 15b). Alternatively, specification information indicating the equipment (particularly the presence or absence of optional equipment) of the target vehicle may be pre-stored in the storage device of the onboard ECU (e.g., the ECU 18a) or the storage device 520 of the navigation system 500. Alternatively, the user may input specification information regarding the equipment (particularly the presence or absence of optional equipment) of the target vehicle via the input device 540. The control device 510 may also refer to this specification information to determine whether the target vehicle has charging equipment.

[0102] If the target vehicle is determined to be without charging equipment (e.g., the target vehicle is vehicle 100B) (No in S104), the control device 510 controls the notification device 530 in S105, referring to map information, to guide the target vehicle (first guidance). Specifically, the control device 510 guides the target vehicle to a replacement location in S105 and does not guide the target vehicle to a supply location. If the target vehicle is determined to be equipped with charging equipment (e.g., the target vehicle is vehicle 100A) (Yes in S104), the control device 510 controls the notification device 530 in S106, referring to map information, to guide the target vehicle (second guidance). Specifically, the control device 510 guides the target vehicle to both a replacement location and a supply location in S106. A replacement location is a location where a replacement device capable of replacing the target vehicle's battery pack 20 is installed. The supply location is a location where an EVSE capable of supplying power to the target vehicle's battery pack 20 is installed. Control device 510 continues guidance in each of S105 and S106 until receiving a request from the user to terminate guidance. The user can also request the control device 510 to terminate guidance via display 531 (touch panel) or input device 540. Upon receiving the request from the user, control device 510 terminates guidance. Process flow F1 thus ends.

[0103] Figure 7 exemplifies the guidance styles in S105 and S106. Figure 6 Refer to it together Figure 7The display 531 displays information to the user U of the target vehicle (vehicles 100A, 100B). In S105, the display 531 displays screen Nv11 to guide the target vehicle driven by user U. Screen Nv11 displays the replacement location on the map using image D1. Screen Nv11 does not display the supply location. In S106, the display 531 displays screen Nv12 to guide the target vehicle driven by user U. Screen Nv12 displays the replacement location on the map using image D1 and the supply location on the map using image D2. Screen Nv12 displays both the replacement location and the supply location in a manner that allows the user to distinguish between them. For example, screen Nv12 displays the replacement location and the supply location on the map using different graphics, such as images D1 and D2. Screens Nv11 and Nv12 each display a map of the target vehicle's surroundings and indicate the target vehicle's current location on the map using image P. The surrounding map and current location of the target vehicle are sequentially updated. When the user U selects and designates a location from at least one location displayed on screen Nv11 or Nv12, the control device 510 may search for a route from the target vehicle's current location (image P) to the designated location (destination), and display the search results on the display 531. Furthermore, the control device 510 may control the speaker 532 to provide voice guidance to the user U based on the search results. The user U may also designate a destination by operating the touch panel of the display 531.

[0104] As described above, the navigation system 500 according to this embodiment is configured to execute Figure 6 The navigation system 500 guides the user to use the replacement device 350 (see Figure 3 、 Figure 4 ) The battery pack 20 of each vehicle 100A, 100B is loaded and unloaded (refer to Figure 7Navigation system 500 includes a guidance device that presents information for guiding the target vehicle (vehicles 100A, 100B) to at least one of a replacement location and a supply location. In this embodiment, control device 510, storage device 520, and reporting device 530 cooperate to function as a guidance device. The guidance device guides the target vehicle to the supply location when a guidance condition is met, and does not guide the target vehicle to the supply location when the guidance condition is not met. In this embodiment, the guidance condition is met if the target vehicle has charging equipment ("Yes" in S104), and is not met if the target vehicle does not have charging equipment ("No" in S104). For example, if the target vehicle is vehicle 100A, the guidance condition is met, and navigation system 500 guides the target vehicle to both the replacement location and the supply location. If the target vehicle is vehicle 100B, the guidance condition is not met, and navigation system 500 guides the target vehicle only to the replacement location, which is the replacement location or the supply location.

[0105] Navigation system 500 having the above-described structure can be installed in either vehicle 100A or 100B. Vehicle 100B cannot use the supply base, so it is expected that the convenience for the user of vehicle 100B will be reduced when vehicle 100B is guided to the supply base. Therefore, in navigation system 500, if it is expected that the user's convenience will be reduced when guiding the vehicle to the supply base, the guidance condition is not met. This can prevent the reduction in user convenience. On the other hand, vehicle 100A, which can use the supply base, is guided to the supply base. This improves the convenience for the user of vehicle 100A.

[0106] The guidance device of the navigation system 500 according to the above embodiment provides the first information (see FIG. 1 ) to guide the target vehicle to the replacement location and not to the supply location when the guidance condition is not satisfied. Figure 7 In the screen Nv11 in FIG), when the guidance condition is satisfied, the second information for guiding the target vehicle to both the replacement base and the supply base is prompted (refer to Figure 7 However, the guidance device is not limited thereto, and may be configured to present third information indicating that the target vehicle is to be guided to the supply location and that the target vehicle is not to be guided to the replacement location.

[0107] The control device 510 of the navigation system 500 may also replace Figure 6 The processing flow F1 shown in FIG. Figure 8 The processing flow F2 is shown. Figure 8 It shows Figure 6The flowchart of the first modified example of the process flow F1 is shown. The process flow F2 is the same as the process flow F1 except that S107, S108A, S108B, and S108C are added.

[0108] Reference Figure 8 In this variation, if it is determined that the target vehicle does not have charging equipment ("No" in S104), the process proceeds to S108A. If it is determined that the target vehicle has charging equipment ("Yes" in S104), the process proceeds to S108B. In each of S108A and S108B, the control device 510 determines whether the replacement equipment (equipment for attaching and detaching the battery pack 20) of the target vehicle is functioning properly. If an abnormality occurs in the replacement equipment, a "No" determination is made in each of S108A and S108B. For example, if an onboard sensor used in replacing the battery pack 20 fails, a "No" determination is made in each of S108A and S108B.

[0109] If the determination in S108A is "No," in the following S108C, control device 510 causes reporting device 530 to execute a predetermined reporting process, and then terminates processing flow F2. In S108C, for example, display 531 may display a message to the user informing them that, despite the reduced energy reserve of the target vehicle, the target vehicle cannot be recharged due to an equipment malfunction. Alternatively, speaker 532 may emit a warning sound.

[0110] If the determination in S108B is "No," the process proceeds to S107. In S107, the control device 510 of the navigation system 500 controls the reporting device 530 by referring to the map information to guide the target vehicle (third guidance). Specifically, in S107, the control device 510 guides the target vehicle to the supply point and does not guide the target vehicle to the replacement point. For example, the display 531 displays screen Nv13 to guide the target vehicle driven by the user. Screen Nv13 displays the supply point on the map using image D2. Screen Nv13 does not display the replacement point.

[0111] If the replacement of the target vehicle is normal, the answer is "yes" in each of S108A and S108B. If the answer is "yes" in S108A, the display 531 displays the screen Nv11 (see Figure 7 If the result of the determination in S108B is “Yes”, then in the subsequent S106, the display 531 displays the screen Nv12 (see Figure 7 ).

[0112] In the above Figure 8In the modified example shown, when the guidance condition is not satisfied and the replacement of the equipment of the target vehicle is normal, the navigation system 500 presents the first information (see Figure 7 If the guidance condition is satisfied and the replacement of the equipment of the target vehicle is normal, the navigation system 500 displays the second information (see Figure 7 When the guidance condition is satisfied and an abnormality occurs in the replacement of the equipment of the target vehicle, the navigation system 500 displays the third information (see Figure 8 (Screen Nv13 in the figure). With this configuration, if the target vehicle cannot use the replacement device, the target vehicle will not be directed to the replacement location. This prevents a reduction in user convenience. Furthermore, in this case, the target vehicle is directed to the supply location, thereby improving user convenience. Furthermore, in this variation, the guidance condition is met if the target vehicle has charging equipment.

[0113] The navigation system 500 may be configured to be able to acquire information regarding a plurality of replacement locations (replacement location information) and information regarding a plurality of supply locations (supply location information). Figure 9 This is a diagram for explaining an example of replacement location information and supply location information.

[0114] Reference Figure 9 , the server 900 maintains location information and inventory information related to a plurality of replacement bases registered to the server 900. In the inventory information, the replacement base corresponding to the inventory information indicates the inventory status of replacement battery packs (battery pack B2) that can be installed on the target vehicle instead of the battery pack 20 (battery pack B1) installed on the target vehicle at the current time point. The inventory information indicates, for example, the number of replacement battery packs possessed by the corresponding replacement base and the storage capacity (for example, SOC) and specifications (for example, maximum output power, maximum regenerative power, and capacity) of each replacement battery pack. The location information and inventory information are stored in a storage device (not shown) of the server 900. The server 900, for example, receives information from the server 380 ( Figure 3 ) information, and updates the inventory information of the corresponding replacement location. The storage device of server 900 stores location information and inventory information related to multiple registered replacement locations, distinguished by replacement location identification information. This information is equivalent to an example of replacement location information.

[0115] Server 900 also stores location information and EVSE information related to multiple supply locations registered with server 900. The EVSE information indicates the current number of users and specifications (e.g., charging method and rated output) for each EVSE (e.g., DC-EVSE 400A and / or AC-EVSE 400B) located at the supply location corresponding to the EVSE information. The charging method can also be indicated by the charging specifications. The location information and EVSE information are stored in the storage device of server 900. For example, server 900 updates the EVSE information for the corresponding supply location based on information from each EVSE located at each supply location. The storage device of server 900 stores the location information and EVSE information related to the multiple registered supply locations, separated by supply location identification information. This information constitutes an example of supply location information.

[0116] The navigation system 500 mounted on the target vehicle (vehicle 100A, 100B) is configured to be able to communicate with the server 900. For example, the control device 510 communicates wirelessly with the server 900 via the wireless communication device 560. The control device 510 can obtain the above information from the server 900. Moreover, the control device 510 of the navigation system 500 having such a configuration can also replace Figure 6 The processing flow F1 shown in FIG. Figure 10 The process flow F3 shown, or Figure 11 The process flow F4 is shown.

[0117] Figure 10 It shows Figure 6 The process flow F3 is similar to the process flow F2 (except that S109A to S109C and S110A are added). Figure 8 )same.

[0118] Reference Figure 10 In this variation, if display 531 determines that a guidance request has been received ("YES" in S103), processing proceeds to S110A. In S110A, control device 510 searches for replacement and supply locations within a predetermined search area. The search area may also be the area surrounding the target vehicle. If the search fails to find a replacement or supply location, the search area may be expanded and the search performed again. Furthermore, control device 510 obtains location information and EVSE information for at least one supply location found within the search area. Processing then proceeds to S104.

[0119] If it is determined in S104 that the target vehicle has charging equipment ("YES" in S104), the control device 510 determines in S109A-S109C whether other requirements related to the guidance conditions are met. In S109A, the control device 510 determines whether the target vehicle's charging equipment is functioning properly. If at least one of the target vehicle's DC charging equipment (DC charging relay 14a and DC charging inlet 14b) and AC charging equipment (AC charger 15a and AC charging inlet 15b) is functioning properly, the determination in S109A is "YES." In S109B, the control device 510 determines, for example, based on EVSE information, whether one of the at least one supply locations found through the search has an EVSE compatible with the target vehicle. The EVSE compatible with the target vehicle may also meet pre-defined requirements for the target vehicle (e.g., requirements related to the charging method and rated output). However, if an abnormality occurs in either the DC charging equipment or the AC charging equipment of the target vehicle, only the EVSE (DC-EVSE 400A or AC-EVSE 400B) corresponding to the normal charging equipment is determined to be compatible with the target vehicle. In S109C, the control device 510 determines, based on the EVSE information, whether any of the at least one supply base found by the search includes an EVSE with a user count of less than a predetermined number.

[0120] In this variation, the guidance condition is met if all of the following conditions are met: the target vehicle has charging equipment (first requirement), the target vehicle's charging equipment is functioning properly (second requirement), a supply base with energy supply equipment corresponding to the target vehicle is located within a predetermined area (third requirement), and a supply base containing energy supply equipment with a user count of no more than a predetermined number is located within a predetermined area (fourth requirement). If any of these conditions are not met, the guidance condition is not met. If at least one of the first through fourth conditions is not met ("No" in any of S104 and S109A-S109C), the process proceeds to S108A. If all of the first through fourth conditions are met ("Yes" in all of S104 and S109A-S109C), the process proceeds to S108B.

[0121] If the result of the determination in S108A is "Yes", the control device 510 determines that the location change is the target of the guidance, and in the subsequent S105, the display 531 displays the screen Nv11 (see Figure 7However, the screen Nv11 displays the replacement base (guidance target) found in the search of S110A. If the judgment in S108B is "No", the control device 510 determines the supply base as the guidance target, and in the next S107, the display 531 displays the screen Nv13 (refer to Figure 8 However, screen Nv13 displays the supply base (guidance target) that meets the third and fourth requirements. If the judgment in S108B is "Yes", the control device 510 determines the supply base and the replacement base as guidance targets, and in the next S106, the display 531 displays screen Nv12 (refer to Figure 7 However, the screen Nv12 displays the supply bases (guidance targets) that satisfy the third and fourth requirements and the replacement bases (guidance targets) found in the search in S110A.

[0122] In the above Figure 10 In the illustrated variation, the guidance conditions include the first through fourth requirements. However, this is not limiting, and the guidance conditions may be modified as appropriate. For example, at least one of the second through fourth requirements may be omitted. The third and fourth requirements may also be omitted. Furthermore, the guidance conditions may include only one requirement selected from the second through fourth requirements in addition to the first requirement.

[0123] Figure 11 It shows Figure 6 The process flow F4 is similar to the process flow F1 ( FIG. 1 ), except that S104A and S104B are used instead of S104, and S107, S110B, S111, and S112 are added. Figure 6 )same.

[0124] Reference Figure 11 In process flow F4, if it is determined that display 531 has received a guidance request ("YES" in S103), processing proceeds to S110B. In S110B, control device 510 searches for replacement locations and supply locations within the predetermined search area. Furthermore, control device 510 obtains location information and inventory information for at least one replacement location found within the search area. Processing then proceeds to S111. In the navigation system 500 of this variation, control device 510, storage device 520, and reporting device 530 cooperate to function as both a guidance device and a search device.

[0125] In S111, control device 510 uses inventory information to determine whether any of the at least one replacement locations found through the search has a replacement battery pack for the target vehicle. If a replacement battery pack for the target vehicle exists within the search area ("YES" in S111), control device 510 uses the inventory information to determine a replacement battery pack for guidance in S112. Specifically, control device 510 selects a replacement battery pack that meets predetermined requirements from among the one or more replacement locations (candidates for guidance) that have a replacement battery pack for the target vehicle. The predetermined requirements are determined regarding at least one of the storage capacity, maximum output power, maximum regenerative power, and capacity of the replacement battery pack (power storage device). For example, with respect to a replacement battery pack, the predetermined necessary conditions may also include at least one of the storage capacity (e.g., SOC) being above a predetermined first reference value, the maximum output power being above a predetermined second reference value, the maximum regenerative power being above a predetermined third reference value, and the capacity (the amount of power in a fully charged state) being above a predetermined fourth reference value.

[0126] After determining the replacement location for guidance in S112, the process proceeds to S104B. If a replacement location with a replacement battery pack for the target vehicle is not within the search area ("No" in S111), the process proceeds to S104A. In S104A and S104B, the control device 510 determines whether the target vehicle has charging equipment.

[0127] If the judgment result in S104A is "Yes", the control device 510 determines the supply base as the guidance target, and in the next S107, the display 531 displays the screen Nv13 (see Figure 8 However, the screen Nv13 displays the supply base (guidance target) found in the search of S110B. If the judgment in S104B is "No", the control device 510 determines the replacement base as the guidance target, and in the next S105, the display 531 displays the screen Nv11 (refer to Figure 7 However, the screen Nv11 displays the replacement base (guidance target) determined in S112. If the judgment in S104B is "Yes", the control device 510 determines the supply base and the replacement base as guidance targets, and in the next S106, the display 531 displays the screen Nv12 (refer to Figure 7 However, the screen Nv12 displays the supply base (guidance target) found in the search in S110B and the replacement base (guidance target) determined in S112.

[0128] The target vehicle may also include multiple battery packs (power storage devices). Alternatively, the vehicle 100A ( Figure 1 ) and will Figure 12 The vehicle 100C shown is used as the target vehicle instead of the vehicle 100B ( Figure 2 ) and will Figure 13 The illustrated vehicle 100D is used as the subject vehicle. Figure 12 It shows Figure 1 FIG. 1 is a diagram showing a modified example of vehicle 100A. Figure 13 It shows Figure 2 FIG. 1 is a diagram showing a modified example of vehicle 100B.

[0129] Reference Figure 12 The vehicle 100C includes a plurality of battery packs and a vehicle body 10C. Figure 12 In the example shown, vehicle 100C includes at least three battery packs (first through third battery packs). The number of battery packs may be greater than three and less than ten. However, this is not limiting; the number of battery packs may be two or greater than ten. Vehicle body 100C includes terminals T11A and T12A for detachably attaching a first battery pack, terminals T11B and T12B for detachably attaching a second battery pack, and terminals T11C and T12C for detachably attaching a third battery pack. Vehicle body 10C is configured to allow at least the first through third battery packs to be detachably attached. Vehicle body 10C also includes a parallel circuit CR13. Parallel circuit CR13 connects terminals T11A, T11B, and T11C (high-voltage power lines) in parallel, and also connects terminals T12A, T12B, and T12C (low-voltage power lines) in parallel. The parallel circuit CR13 connects the plurality of battery packs (including the first to third battery packs) connected to the vehicle body 10C in parallel. However, the connection pattern of the plurality of battery packs can be modified as appropriate, and they may also be connected in series.

[0130] Reference Figure 13 The vehicle 100D includes a plurality of battery packs and a vehicle body 10D. Figure 12 The vehicle 100C shown in the figure does not include the DC charging relay 14a, DC charging inlet 14b, AC charger 15a, and AC charging inlet 15b. The parallel circuit CR13 provided in the vehicle body 10D connects a plurality of battery packs (including the first to third battery packs) connected to the vehicle body 10D in parallel.

[0131] Vehicles 100C and 100D each have Figure 6 However, the navigation system 500 mounted on each of the vehicles 100C and 100D replaces Figure 6 The processing flow F1 shown in FIG. Figure 14 In the description of this modification, the vehicle (vehicle 100C or 100D) including the navigation system 500 that executes the processing flow F5 is referred to as a "target vehicle."

[0132] Figure 14 It shows Figure 6 The process flow F5 is similar to the process flow F4 except that S112, S105, and S106 are replaced with S112A, S105A, and S106A. Figure 11 ) are the same. Figure 14 In the process, steps before S110B are omitted.

[0133] Reference Figure 14 In this variation, if it is determined that a replacement location with replacement battery packs for the target vehicle exists within the search area ("YES" in S111), control device 510 classifies the replacement locations in S112A using inventory information. Specifically, control device 510 classifies each of at least one replacement location within the search area (more specifically, a replacement location with replacement battery packs for the target vehicle) as either a full replacement location or a partial replacement location. A full replacement location is a replacement location (a first replacement location) that can replace all of the multiple battery packs in the target vehicle. In other words, a full replacement location can replace all of the battery packs in the target vehicle. A partial replacement location is a replacement location (a second replacement location) that can replace only a portion of the multiple battery packs in the target vehicle. In other words, a partial replacement location cannot replace some of the battery packs in the target vehicle.

[0134] Next, in S104B, the control device 510 determines whether the target vehicle has charging equipment. If the determination in S104B is "No," in the subsequent S105A, the control device 510 determines at least one of the full-replacement location and the partial-replacement location identified in S112A as a guidance target, and guides the target vehicle to the guidance target. If the guidance targets include both full-replacement locations and partial-replacement locations, the display 531 displays both full-replacement locations and partial-replacement locations in a manner that allows the user to distinguish between them, in accordance with the control command from the control device 510. Specifically, the display 531 displays screen Nv20, for example. Screen Nv20 displays full-replacement locations and partial-replacement locations on a map, for example, using images D3 and D4 with different patterns to distinguish between these locations. If the judgment in S104B is "yes", in the following S106A, the control device 510 determines at least one of the supply base found in the search in S110B and the full replacement base and partial replacement base identified in S112A as the guidance target, and guides the target vehicle to the guidance target. In the case where the guidance target includes both full replacement bases and partial replacement bases, the display 531 displays both full replacement bases and partial replacement bases in a format that allows the user to distinguish between them in accordance with the control command from the control device 510. For example, the display 531 displays an image D2 (showing the supply base (guidance target)) added to the map on screen Nv20. Figure 7 ) to form a screen (not shown).

[0135] Figure 6 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 14 The processing flow shown can be changed appropriately. For example, the order of processing can be changed according to the purpose, and unnecessary steps can be omitted. In addition, the content of any processing can be changed. For example, in Figure 14 In the processing flow F5 shown, in S112A, the control device 510 identifies all replacement locations and some replacement locations, and in each of S105A and S106A, the display 531 distinguishes and displays all replacement locations and some replacement locations. However, the processing flow F5 is not limited to this, and the processing flow F5 may be modified so that in S112A, the control device 510 identifies replacement locations with high-quality battery packs, and in each of S105A and S106A, the display 531 distinguishes and displays replacement locations with high-quality battery packs and replacement locations with only low-quality battery packs. In addition, in the processing flow F1 ( Figure 6), when a guidance request is received by an input device (e.g., display 531 or input device 540) of navigation system 500 ("YES" in S103), control device 510 determines a guidance destination including at least one of a replacement destination and a supply destination, and guides the target vehicle to the determined guidance destination. However, navigation system 500 is not required to receive guidance requests from the user.

[0136] Figure 15 It shows Figure 6 Flowchart of the fifth variation of the processing flow F1 shown in FIG. Figure 15 , process F6 is from process F1 ( Figure 6 ) The processing flow of S102 and S103 is omitted. In processing flow F6, if the stored energy (energy storage capacity) of battery pack 20 mounted on the target vehicle is lower than the reference value ("YES" in S101), control device 510 determines a guidance destination including at least one of a replacement location and a supply location, and guides the target vehicle to the determined guidance destination.

[0137] In the above-described embodiment and various variations, navigation system 500 is installed in the target vehicle. However, the configuration is not limited to this. At least a portion of the functions of navigation system 500 may be implemented in the cloud through cloud computing. Furthermore, navigation system 500 may be installed in a mobile terminal in addition to or in place of the target vehicle. Figure 16 This figure shows mobile terminal 200A equipped with navigation system 500. In navigation system 500 installed in mobile terminal 200A, display 531 can also display information to user U in a target vehicle (e.g., vehicle 100A, 100B, 100C, or 100D). Display 531 (e.g., a touch panel display) and input device 540 can each also receive requests from user U (e.g., a request for guidance).

[0138] The navigation system 500 mounted on the mobile terminal 200A may also replace Figure 6 The processing flow F1 shown is executed Figure 17 Processing flow F7 is shown. Figure 17 It shows Figure 6 Flowchart of the sixth variation of the processing flow F1 shown in FIG. Figure 17 When the application software installed in the mobile terminal 200A is started, the display 531 of the mobile terminal 200A displays, for example, screen Sc2. Screen Sc2 is a transition from screen Sc1 ( Figure 6 ) The screen of message M1 is omitted. Then, when the user operates the operation unit M3 in the screen Sc2, the control device 510 of the mobile terminal 200A starts the process F7. The process F7 is a process from the process F1 ( Figure 6) The processing flow of S101 to S103 is omitted. Therefore, in processing flow F7, similar to processing flow F1, the control device 510 determines a guidance destination including at least one of a replacement location and a supply location, and guides the target vehicle to the determined guidance destination.

[0139] Screen Nv12 ( Figure 7 ) Display the replacement base and supply base separately on the same map. In addition, screen Nv20 ( Figure 14 ) Differentiate between displaying all or some of the bases changed on the same map. However, this is not limited to this, and the display style of each base can be changed as appropriate. Figure 18 : is a diagram showing a modified example of the display style of the replacement base and the supply base. Figure 18 , for example, in Figure 14 In S106A, the control device 510 may also cause the display 531 to display windows W1 to W3. A map of the same location is displayed on each of windows W1 to W3. However, only the replacement bases (all replacement bases and some replacement bases) are displayed on the map in window W1, only the supply bases are displayed on the map in window W2, and only all replacement bases are displayed on the map in window W3. Figure 18 Window W3 is shown as being in the foreground, with windows W1 and W2 hidden behind window W3. However, the user can arbitrarily select which window to bring to the front. For example, a window (any one of windows W1 to W3) selected by the user via the GUI (Graphical User Interface) on display 531 can be brought to the front.

[0140] In the above-described embodiment and various variations, the types of locations are distinguished by changing the shape or pattern of the markers displayed on the map. However, the method of distinguishing locations may be modified as appropriate. For example, the color or size of the markers may be changed according to the location type. Furthermore, specific locations may be emphasized (e.g., by being more prominent than other locations). Furthermore, the markers displayed on the map are not limited to circular or rectangular shapes; they may also be numbers, text, symbols, icons, or a combination thereof. Display 531 may also utilize XR technology to present information related to each location to the user in an intuitive and easily understood manner (e.g., using three-dimensional VR images).

[0141] Figure 1 、 Figure 2 、 Figure 12 、 Figure 13The structure of the vehicle body and battery pack shown can be modified as appropriate. For example, at least one of SMR13 and 23 can be omitted. For example, SMR13 can be omitted. Alternatively, SMR23 can be omitted. In addition, at least one of the DC charging socket 14b and the AC charging socket 15b can be omitted, and can be changed to a single charging socket shared by AC / DC. The location of the charging socket is arbitrary. The charging socket can also be set on any surface of the vehicle body, front, back, left, right, top, or bottom. The vehicle body can also be configured to enable contactless charging. The vehicle body can also be equipped with solar panels. The battery pack can also have a power supply for starting the control unit (ECU28a) in the battery pack. In addition, the circuit CR22 in the battery pack can also include a temperature adjustment device driven by power from the auxiliary equipment battery 17. The power storage device is not limited to the battery pack and can also have a pack-less structure.

[0142] The energy storage device is not limited to an electricity storage device. The vehicle may also be an FCEV (fuel cell electric vehicle), and the removable energy storage device may also be a hydrogen tank in the FCEV. Figure 19 5 is a diagram showing a fuel cell vehicle equipped with a navigation system 500. Figure 19 The FCEV 100E is configured to include a hydrogen tank 20A and can travel using hydrogen stored in the hydrogen tank 20A. The navigation system 500 mounted on the FCEV 100E has Figure 6 The display 531 can also replace the screen Nv11 ( Figure 7 )、screenNv12( Figure 7 ), screen Nv13 ( Figure 8 ), and screens Nv31, Nv32, and Nv33 are displayed, respectively. In each of screens Nv31 and Nv32, the replacement location shown on the map by image D31 is a location equipped with a replacement device configured to remove hydrogen tank 20A from FCEV 100E and install another hydrogen tank in FCEV 100E. In each of screens Nv32 and Nv33, the supply location shown on the map by image D32 is a location (e.g., a hydrogen station) equipped with energy supply equipment that supplies hydrogen (energy) to hydrogen tank 20A.

[0143] It is also possible to make replacement equipment optional in vehicles. For example, the navigation system installed in a vehicle equipped with charging equipment as standard equipment can be replaced Figure 6 The processing flow F1 shown is executed Figure 20 The process flow shown is F8. Figure 20 It shows Figure 6 Flowchart of the seventh variation of the processing flow shown. Figure 20In S201, the navigation system determines whether the target vehicle has replacement equipment (optional equipment). If the target vehicle is determined not to have replacement equipment ("No" in S201), in S202, the navigation system controls the reporting device to execute the third guidance described above. Specifically, the navigation system guides the target vehicle to the supply location and does not guide the target vehicle to the replacement location. If the target vehicle is determined to have replacement equipment ("Yes" in S201), in S203, the navigation system controls the reporting device to execute the second guidance described above. Specifically, the navigation system guides the target vehicle to both the replacement location and the supply location. S203 can also be modified to execute the first guidance described above instead of the second guidance. Alternatively, a step of determining whether the replacement equipment is normal can be used in place of or in addition to S201.

[0144] Vehicles are not limited to passenger cars; they can also be buses, trucks, or work vehicles (tractors, forklifts, etc.). Vehicles can also be configured to operate unmanned, either autonomously or remotely. They can also be automated guided vehicles (AGVs).

[0145] The above-mentioned various modifications may be implemented in any combination.

[0146] The embodiments disclosed herein are by way of illustration in all points and should not be construed as limiting.
