[0008] An example configuration of a vehicle 1 according to this embodiment (hereinafter simply referred to as "vehicle 1") will be described below with reference to the drawings. This embodiment is merely an example and does not limit the contents of this disclosure. Furthermore, the size, scale, aspect ratio, etc. of each part shown in the drawings can be changed as appropriate based on the knowledge of a person skilled in the art.

[0009] [First embodiment] <1. Example of vehicle 1 configuration> An example configuration of a vehicle 1 according to the first embodiment will be described with reference to Fig. 1-2. In one embodiment, the vehicle 1 is an electric motorcycle. The vehicle 1 is capable of traveling by supplying power from a battery to a motor and transmitting the power of the motor to tires.

[0010] The vehicle 1 includes a main frame 10 and a control system 42. The main frame 10 is a framework for attaching each part to the vehicle 1. The main frame 10 is provided with a handlebar 5, a front light 24, a board 14, a seat 12, a fork 48, a first battery storage section 32a, a second battery storage section 32b, and a two-wheel support frame 18a. Other parts such as safety equipment may also be provided on the main frame 10. Each part may be provided directly to the main frame 10, or indirectly via connecting parts or the like.

[0011] The handlebars 5 are a part that allows the rider to operate the vehicle 1. The handlebars 5 are connected to the main frame 10 via a stem. The rider can rotate the fork 48 by rotating the handlebars 5 around the axial direction of the stem, thereby controlling the direction of travel of the vehicle 1. The handlebars 5 have a throttle 26 and a brake lever 28. By opening the throttle 26, the rider can operate motors 31a and 31b, which will be described later, and cause the vehicle 1 to travel. By pulling the brake lever 28, the rider can operate a brake 22, which will be described later, and cause the vehicle 1 to slow down.

[0012] The front light 24 is a part that emits light ahead of the vehicle 1. The front light 24 may be controlled to be turned on at least when the vehicle 1 is traveling. The front light 24 may be controlled to be turned on when the vehicle 1 is in an activated state (for example, when a physical key is inserted into the vehicle 1, and when the vehicle 1 has authenticated the passenger using the passenger's terminal device, electronic key, etc.).

[0013] The board 14 is a curved, plate-like part in which a luggage carrier 140, a floorboard 142, and a leg shield 144 are continuously formed. The luggage carrier 140 is a portion on which luggage or a housing for carrying luggage can be placed. The floorboard 142 is a portion on which a passenger seated in the seat 12 can place their feet. A portion of the floorboard 142 may be detachable, thereby allowing a small battery SB (described later) to be detachably attached to the first battery housing 32a. The leg shield 144 is a portion that can protect the passenger's legs from headwinds while traveling and from sand and gravel flying from the direction of travel. The board 14 may be formed such that the luggage carrier 140, the floorboard 142, and the leg shield 144 are integrally formed, or may be formed so that the surfaces are flush when connected.

[0014] The fork 48 supports the front wheel 16a and the brake 22. The brake 22 is connected, for example, via a wire, to a brake lever 28 on the right side of the handlebars 5. The fork 48 may have a suspension.

[0015] The first battery storage section 32a is configured to allow one small battery SB to be attached and detached. The first battery storage section 32a is provided on the surface of the main frame 10 opposite the floor board 142. That is, the first battery storage section 32a can be in the following state (1) or (2). (1) The small battery SB is not stored. (2) The small battery SB is stored. The first battery storage section 32a may include a sensor capable of detecting whether or not the small battery SB is stored therein.

[0016] The second battery storage section 32b is supported by the two-wheel support frame 18a and the main frame 10. The second battery storage section 32b is configured to allow up to two small batteries SB to be attached and detached. The second battery storage section 32b is also configured to allow one large battery LB, which will be described later, to be attached and detached. In other words, the second battery storage section 32b can be in any of the following states (1) to (4). (1) No batteries are stored. (2) When one small battery SB is stored. (3) Two small batteries SB are stored. (4) When one large battery LB is stored. The second battery storage section 32b may include a sensor capable of detecting whether the large battery LB and the small battery SB are stored therein.

[0017] Hereinafter, the first battery storage section 32a and the second battery storage section 32b will be collectively referred to as the "battery storage section 32." Furthermore, the small battery SB and the large battery LB will be collectively referred to as the "battery."

[0018] The two-wheel support frame 18a has two pairs of swing arms. The two pairs of swing arms support the rear wheels 16b1 and 16b2, respectively. The two-wheel support frame 18a is configured to be detachable from the main frame 10. The rear wheels 16b1 and 16b2 each have a built-in motor 31a, 31b. The motor 31a receives power from a battery stored in a battery storage section 32 to rotate the rear wheel 16b1. Similarly, the motor 31b receives power from a battery stored in the battery storage section 32 to rotate the rear wheel 16b2. Although not shown in the figures, each of the two pairs of swing arms may support a brake. This brake may be connected to a brake lever 28 on the left side of the handlebars 5, for example, via a wire.

[0019] Hereinafter, the motors 31 will be collectively referred to as "motors 31." Also, hereinafter, the rear wheels 16b1, 16b2 will be collectively referred to as "rear wheels 16b."

[0020] The control system 42 controls the operation of the motor 31 based on whether or not a battery is stored in the battery storage section 32. The control system 42 is not shown in Figures 1-2. The configuration and operation of the control system 42 will be described later with reference to Figures 10-13.

[0021] Although not shown, the vehicle 1 may further include a charging port. The charging port can be connected to an external power supply device and is configured to be able to charge the small battery SB and the large battery LB stored in the battery storage section 32.

[0022] 2. Configuration example of battery storage section 32 3-9 shows an example of the configuration of the battery storage unit 32. FIG. 3-4 shows an example of the configuration of the first battery storage unit 32a. FIG. 5-9 shows an example of the configuration of the second battery storage unit 32b.

[0023] 3(A) and 3(B) are diagrams showing configuration examples of the first battery housing 32a when the small battery SB is not stored and when the small battery SB is stored, respectively. As described above, the first battery housing 32a is configured so that the small battery SB can be attached and detached. That is, the occupant can change the first battery housing 32a to the state shown in FIG. 3(B) by inserting the small battery SB through the opening of the first battery housing 32a in the state shown in FIG. 3(A) (i.e., the surface of the first battery housing 32a in the negative y-axis direction). Conversely, the occupant can return the first battery housing 32a to the state shown in FIG. 3(A) by removing the small battery SB from the opening of the first battery housing 32a in the state shown in FIG. 3(B).

[0024] Although not shown in the example of Fig. 3, the opening of first battery storage section 32a may have a lid. When the opening of first battery storage section 32a is located on the floorboard 142 side, a part of floorboard 142 may be configured to serve as the lid of first battery storage section 32a.

[0025] 4 is an example of a cross-sectional view along the xy plane of the first battery housing 32a in the state of FIG. 3(B). The first battery housing 32a has a positive contact 34a and a negative contact 34b therein. In contrast, the small battery SB has a positive terminal 36a and a negative terminal 36b. The positive contact 34a is electrically connected to the positive terminal 36a. Similarly, the negative contact 34b is electrically connected to the negative terminal 36b.

[0026] Figures 5-7 are diagrams showing examples of the configuration of the second battery storage section 32b when no battery is stored, when two small batteries SB are stored, and when one large battery LB is stored, respectively.

[0027] The large battery LB is larger than the small battery SB in at least one of width, length, depth, and discharge capacity. In one embodiment, the large battery LB is configured so that at least one of width, length, depth, and discharge capacity is approximately an integer multiple of the small battery SB. For example, the width of the large battery LB may be within a range of 1.8 to 2.2 times, or 1.9 to 2.1 times, the width of the small battery SB. Alternatively, the width of the large battery LB may be within a range of 2.7 to 3.3 times, 2.8 to 3.2 times, or 2.9 to 3.1 times, the width of the small battery SB. Hereinafter, at least one of the width, length, depth, and discharge capacity of the battery will be referred to as the "battery size."

[0028] As shown in Fig. 6, the second battery storage section 32b is configured to allow up to two small batteries SB to be attached or detached. That is, the occupant can change the second battery storage section 32b to the state shown in Fig. 6 by inserting two small batteries SB through the opening of the second battery storage section 32b in the state shown in Fig. 5 (i.e., the surface of the second battery storage section 32b in the negative y-axis direction). Conversely, the occupant can return the second battery storage section 32b to the state shown in Fig. 5 by removing both small batteries SB from the opening of the second battery storage section 32b in the state shown in Fig. 6. Note that the second battery storage section 32b may store only one small battery SB.

[0029] As shown in Fig. 7, the second battery storage section 32b is configured to allow one large battery LB to be attached and detached. That is, the occupant can change the state of the second battery storage section 32b to the state shown in Fig. 7 by inserting one large battery LB through the opening of the second battery storage section 32b in the state shown in Fig. 5. Conversely, the occupant can return the second battery storage section 32b to the state shown in Fig. 5 by removing the large battery LB from the opening of the second battery storage section 32b in the state shown in Fig. 7.

[0030] Although not shown in the examples of Figures 5-7, the opening of second battery storage section 32b may have a lid. If the opening of second battery storage section 32b is located on the cargo bed 140 side, a part of cargo bed 140 may be configured to serve as the lid of second battery storage section 32b.

[0031] 8 is an example of a cross-sectional view of the second battery compartment 32b along the C1 section in the state shown in FIG. 6. The second battery compartment 32b has therein a positive contact 34a1, a positive contact 34a2, a positive contact 38a, a negative contact 34b1, a negative contact 34b2, and a negative contact 38b. The positive terminals 36a of the two small batteries SB are electrically connected to the positive contact 34a1 and the positive contact 34a2, respectively. Similarly, the negative terminals 36b of the two small batteries SB are electrically connected to the negative contact 34b1 and the negative contact 34b2, respectively.

[0032] 9 is an example cross-sectional view of the second battery storage section 32b taken along the C2 section in the state shown in FIG. 7. The large battery LB has a positive terminal 40a and a negative terminal 40b. The positive terminal 40a is electrically connected to the positive contact 38a. Similarly, the negative terminal 40b is electrically connected to the negative contact 38b.

[0033] When removed from the battery storage section 32, the small battery SB and the large battery LB can be charged by connecting them to an external electrode supply device.

[0034] <3. Configuration example of control system 42> An example of the configuration and operation of the control system 42 will be described with reference to FIGS.

[0035] FIG. 10 is a functional block diagram showing an example of the relationship between the control system 42 and other components of the vehicle 1. The control system 42 has a control circuit 42a and a power circuit 42b. The control circuit 42a acquires various information related to the vehicle 1 and controls the power circuit 42b based on the information. The power circuit 42b controls the operation of the motor 31 based on input from the control circuit 42a. The control system 42 may be at least a part of the electrical system provided in the vehicle 1. The control circuit 42a may have a computer 70 that controls the power circuit 42b. The control circuit 42a may have an analog electronic circuit that controls the power circuit 42b.

[0036] 11 is a flowchart showing an example of the operation of the control system 42. The control system 42 first acquires the storage status of the battery in the first battery storage section 32a (S10). Specifically, the control system 42 acquires information indicating whether the first battery storage section 32a is in the following state (1) or (2). (1) The small battery SB is not stored. (2) The small battery SB is stored. The information indicating whether the first battery storage section 32a is in the above-mentioned state (1) or (2) may include information regarding the power supplied from the first battery storage section 32a, may include information regarding the potential difference between the positive electrode side contact 34a and the negative electrode side contact 34b of the first battery storage section 32a, and may include a measurement value of a sensor capable of detecting the storage of the small battery SB in the first battery storage section 32a.

[0037] Next, the control system 42 acquires the storage status of the batteries in the second battery storage section 32b (S12). Specifically, the control system 42 acquires information indicating which of the following states (1) to (4) the second battery storage section 32b is in. (1) No batteries are stored. (2) When one small battery SB is stored. (3) Two small batteries SB are stored. (4) When one large battery LB is stored. The information indicating which of the above states (1) to (4) the second battery storage section 32b is in may include information about the power supplied from the second battery storage section 32b, and may include information about at least one of the potential difference between the positive electrode side contact 34a1 and the negative electrode side contact 34b1 of the second battery storage section 32b, the potential difference between the positive electrode side contact 34a2 and the negative electrode side contact 34b2, and the potential difference between the positive electrode side contact 38a and the negative electrode side contact 38b, and may include a measurement value of a sensor capable of detecting the storage of at least one of the small battery SB and the large battery LB in the second battery storage section 32b.

[0038] Next, the control system 42 determines whether or not at least one battery is stored in the battery storage unit 32 (S14).

[0039] If it is determined that at least one battery is stored in the battery storage section 32 (YES in S14), the control system 42 enables the motor 31 (S16a). If the motor 31 is enabled, the control system 42 operates the motor 31 based on the opening of the throttle 26. This drives the rear wheel 16b.

[0040] If it is determined that no battery is stored in the battery storage section 32 (NO in S14), the control system 42 limits the operation of the motor 31 (S16b). The control system 42 may limit the operation of the motor 31 in either of the following cases (1) and (2). (1) The motor 31 is not operated regardless of the opening of the throttle 26 (that is, the motor 31 is stopped). (2) Lowering the maximum output, etc. of the motor 31 based on another power source compared to when it is determined that at least one battery is stored in the battery storage section 32. Note that the other power source may be, for example, a non-removable battery mounted on the vehicle 1 (i.e., a battery stored outside the battery storage section 32).

[0041] 12 is a diagram showing an example of the relationship between the battery storage status in the battery storage section 32 and whether the motor 31 is operable. The control system 42 enables the motor 31 to operate in both a state where one small battery SB or one large battery LB is stored in the battery storage section 32 (patterns p4, p5, p7) and a state where a total of two or more small batteries SB and large batteries LB are stored in the battery storage section 32 (patterns p1, p2, p3, p6). On the other hand, the control system 42 restricts the operation of the motor 31 when no small batteries SB or large batteries LB are stored in the battery storage section 32 (pattern p8).

[0042] The control circuit 42a may include a computer 70. An example of the hardware configuration of the computer 70 when the control circuit 42a includes the computer 70 will be described with reference to Fig. 13. Note that the functions of each device can also be realized by dividing them into multiple devices.

[0043] As shown in FIG. 13, a computer 70 includes a processor 700 , a storage device 702 , an input I / F 704 , a data I / F 706 , a communication I / F 708 , and a display device 710 .

[0044] The processor 700 controls various processes in the computer 70 by executing programs stored in the storage device 702. For example, each functional unit included in the control circuit 42a can be realized by the processor 700 executing the programs stored in the storage device 702.

[0045] The storage device 702 is a storage medium such as a RAM (Random Access Memory), etc. The RAM temporarily stores the program code of the program executed by the processor 700 and data required when the program is executed.

[0046] The storage device 702 may also be a non-volatile storage medium such as a hard disk drive (HDD) or flash memory. The storage device 702 stores an operating system and various programs for implementing the above-described configurations. The storage medium storing the various programs may be a non-transitory computer-readable medium. The storage device 702 may also store tables that register various types of information and a DB that manages the tables. Such programs and data are loaded into the storage device 702 as needed and referenced by the processor 700.

[0047] The input I / F 704 is a device for receiving input from a user. Specific examples of the input I / F 704 include a camera, a button, a microphone, a keyboard, a mouse, a touch panel, various sensors, and a wearable device. The input I / F 704 may be connected to the computer 70 via an interface such as a USB (Universal Serial Bus).

[0048] The data I / F 706 is a device for inputting data from outside the computer 70. A specific example of the data I / F 706 is a drive device for reading data stored in various storage media. The data I / F 706 may be provided outside the computer 70. In this case, the data I / F 706 is connected to the computer 70 via an interface such as a USB.

[0049] The communication I / F 708 is a device for performing data communication via a communication network, either wired or wirelessly, with devices external to the computer 70. The communication I / F 708 may be provided external to the computer 70. In this case, the communication I / F 708 is connected to the computer 70 via an interface such as a USB.

[0050] The display device 710 is a device for displaying various types of information. Specific examples of the display device 710 include a liquid crystal display, an organic EL (Electro-Luminescence) display, and a display of a wearable device. The display device 710 may be provided outside the computer 70. In this case, the display device 710 is connected to the computer 70 via, for example, a display cable. Furthermore, when a touch panel is adopted as the input I / F 704, the display device 710 can be configured as an integral part of the input I / F 704.

[0051] <4. Actions and Effects> Vehicle 1 can store a total of two or more small batteries SB and large batteries LB, and can travel as long as it has at least one small battery SB or one large battery LB (see patterns p4, p5, and p7 in Figure 12). This allows for both long-distance travel and efficient battery use. Vehicle 1 can, for example, travel using the large battery LB while charging the small battery SB with an external power supply device, then swap the used large battery LB with the charged small battery SB, and resume traveling using the small battery SB while the large battery LB is charging. This configuration is particularly useful in businesses such as package delivery, where the vehicle travels for long periods of time per day and returns to a base where a power supply device is installed multiple times a day.

[0052] Furthermore, the vehicle 1 is configured to have a detachable small battery SB, and also has a second battery storage section 32b configured to have a detachable large battery LB. This configuration allows the passenger to select and use a battery depending on their purpose and the charge status of the battery. For example, if the destination is nearby, the passenger can start traveling with one small battery SB stored. If the destination is remote, the passenger can start traveling with two small batteries SB or one large battery LB stored.

[0053] [Second embodiment] 14-15, an example configuration of a vehicle 1 according to the second embodiment will be described. The vehicle 1 according to the first embodiment has been described as having a two-wheel support frame 18a attached to the main frame 10. However, the vehicle 1 according to the second embodiment is provided with a single-wheel support frame 18b instead. The two-wheel support frame 18a has been described as having two sets of swing arms, each supporting a rear wheel 16b. However, the single-wheel support frame 18b has one set of swing arms and supports one rear wheel 16b. In other words, the vehicle 1 according to the first embodiment is a tricycle (one front wheel and two rear wheels), whereas the vehicle 1 according to the second embodiment is a two-wheel vehicle (one front wheel and one rear wheel). The single-wheel support frame 18b, like the two-wheel support frame 18a, is configured to be detachable from the main frame 10. In other words, the rider (or the manufacturer of the vehicle 1) can choose whether the vehicle 1 is a tricycle or a two-wheel vehicle.

[0054] Furthermore, the second battery storage section 32b of the vehicle 1 according to the second embodiment has a lid 33 on the rear wheel 16b side. By opening the lid 33, the passenger can attach or detach a battery to or from the second battery storage section 32b.

[0055] [Third embodiment] Another example of the configuration of the second battery housing section 32b and the battery will be described with reference to FIG.

[0056] In the first embodiment, the second battery storage section 32b has been described as having the positive contacts 34a1, 34a2, and 38a and the negative contacts 34b1, 34b2, and 38b in separate locations. In contrast, the second battery storage section 32b shown in Fig. 16 has a first contact 44 in which the positive contact 34a1 and the negative contact 34b1 are integrated, a second contact 45 in which the positive contact 34a2 and the negative contact 34b2 are integrated, and a third contact 46 in which the positive contact 38a and the negative contact 38b are integrated.

[0057] In the first embodiment, the small battery SB has been described as having the positive terminal 36a and the negative terminal 36b in separate locations. In contrast, the small battery SB shown in Fig. 16(A) has a terminal 36 in which the positive terminal 36a and the negative terminal 36b are integrated. The terminal 36 is electrically connected to the first contact 44 or the second contact 45. The first contact 44 and the second contact 45 may be shaped like a socket, and the terminal 36 may be shaped like a plug for them.

[0058] In the first embodiment, the large battery LB has been described as having the positive terminal 40a and the negative terminal 40b in separate locations. In contrast, the large battery LB shown in FIG. 16(B) has a terminal 40 in which the positive terminal 40a and the negative terminal 40b are integrated. The terminal 40 is electrically connected to a third contact 46. The third contact 46 may be shaped like an outlet, and the terminal 40 may be shaped like a plug for it.

[0059] This configuration allows the structure of the second battery storage section 32b to be simplified.

[0060] [Fourth embodiment] Another example of the configuration of the second battery housing section 32b and the battery will be described with reference to FIG.

[0061] In the first embodiment, the second battery housing section 32b has the positive and negative contacts on the same side, but this is not limited to this. In contrast, the second battery housing section 32b shown in Fig. 17 has positive contacts 34a1 and 34a2 on one side and negative contacts 34b1 and 34b2 on the other side. The small battery SB and the large battery LB are inserted into the second battery housing section 32b shown in Fig. 17 from the positive z-axis direction toward the negative z-axis direction.

[0062] In the first embodiment, an example was described in which the positive and negative terminals of the battery are provided on the same side, but this is not limited to this. Specifically, the small battery SB shown in Fig. 17(A) has a positive terminal 36a on one side and a negative terminal 36b on the other side. Furthermore, the large battery LB shown in Fig. 17(B) has positive terminals 40a1 and 40a2 on one side and negative terminals 40b1 and 40b2 on the other side.

[0063] In the first embodiment, an example was described in which the contact for the small battery SB and the contact for the large battery LB in the second battery housing section 32b are different, but this is not limited to this. Specifically, the positive terminal 36a of the small battery SB can be connected to the positive contact 34a1 of the second battery housing section 32b in FIG. 17, and the positive terminal 40a1 of the large battery LB can also be connected. Furthermore, the positive terminal 36a of the small battery SB can be connected to the positive contact 34a2 of the second battery housing section 32b in FIG. 17, and the positive terminal 40a2 of the large battery LB can also be connected. In other words, the positive contact for the small battery SB in the second battery housing section 32b may be common to the positive contact for the large battery LB.

[0064] The negative terminal 36b of the small battery SB can be connected to the negative contact 34b1 of the second battery housing section 32b in Fig. 17, and the negative terminal 40b1 of the large battery LB can also be connected. The negative terminal 36b of the small battery SB can be connected to the negative contact 34b2 of the second battery housing section 32b in Fig. 17, and the negative terminal 40b2 of the large battery LB can also be connected. In other words, the negative contact for the small battery SB in the second battery housing section 32b may be common to the negative contact for the large battery LB.

[0065] This configuration allows the structure of the second battery storage section 32b to be simplified.

[0066] [Fifth embodiment] The control system 42 may be configured to be able to control the maximum output of the motor 31.

[0067] 18 is a flowchart showing an example of the operation of the control system 42 when controlling the maximum output of the motor 31 based on information related to the vehicle classification. The information related to the vehicle classification includes information indicating the vehicle classification of the vehicle 1. First, the control system 42 acquires the information related to the vehicle classification (S20). The information related to the vehicle classification may be acquired from a storage unit included in the control system 42, from an external information processing device, or by communicating with a terminal device (e.g., a smartphone) held by the passenger.

[0068] Next, the control system 42 determines the vehicle classification based on the information acquired in S20 (S22). For example, if the vehicle classification is a "Class 1 moped," the control system 42 may determine the maximum output of the motor 31 so as to satisfy the safety standards for a Class 1 moped (S24a). Also, if the vehicle classification is a "specified small moped," the control system 42 may determine the maximum output of the motor 31 so as to satisfy the safety standards for a specified small moped (S24b).

[0069] 19 is a flowchart showing an example of the operation of the control system 42 when controlling the maximum output of the motor 31 based on the type of frame attached to the main frame 10. First, the control system 42 acquires information about the frame attached to the main frame 10 (S30). The information about the attached frame may be acquired from a sensor attached to the main frame 10, from a memory unit included in the control system 42, from an external information processing device, or by communicating with a terminal device held by the passenger.

[0070] Next, the control system 42 determines the attached frame based on the information acquired in S30 (S32). For example, if the attached frame is the one-wheel support frame 18b, the control system 42 may determine the maximum output of the motor 31 so as to satisfy the safety standards for specific small mopeds (S34a). If the attached frame is the two-wheel support frame 18a, the control system 42 may determine the maximum output of the motor 31 so as to satisfy the safety standards for minicars (S34b). The control system 42 may determine the vehicle classification of the vehicle 1 based on the attached frame, and may determine the maximum output of the motor 31 so as to satisfy the safety standards for the determined vehicle classification.

[0071] This configuration allows the specifications of vehicle 1 to be changed to meet the safety standards of a specific vehicle classification, thereby improving convenience. In addition to the examples shown in Figure 18, the information related to vehicle classification may include information indicating whether vehicle 1 is a second-class motor bicycle, a minicar, a standard automobile, a large automobile, a standard two-wheeler, a large two-wheeler, or an electrically assisted bicycle, for example.

[0072] In the fifth embodiment, an example was described in which the control system 42 controls the maximum output of the motor 31, but the control system 42 may further control the operation of safety equipment such as turn signals depending on the vehicle classification or the type of frame attached.

[0073] [Additional Notes and Modifications] The details described in the above embodiment may be modified as appropriate within a consistent range. In the above embodiment, the large battery LB is described as being approximately twice the size of the small battery SB, but this is not limited to this. The large battery LB may be approximately three times the size of the small battery SB, or approximately 1.5 times the size. If the large battery LB is approximately three times the size of the small battery SB, the second battery housing 32b may be configured to accommodate up to three detachable small batteries SB and one detachable large battery LB. If the large battery LB is approximately 1.5 times the size of the small battery SB, the second battery housing 32b may be configured to accommodate up to three detachable small batteries SB and two detachable large batteries LB.

[0074] In the above embodiments (e.g., FIG. 16 and the third embodiment), an example has been described in which the terminal 40 of the large battery LB is electrically connected to the third contact 46 of the second battery housing section 32b. However, this is not limiting, and the third contact 46 may be configured to allow connection to the terminal 36 of the small battery SB. FIG. 20 is a diagram showing a state in which the terminal 36 of the small battery SB is connected to the third contact 46 of the second battery housing section 32b. In such a case, the passenger can connect the terminal 36 of the small battery SB to any of the first contact 44, the second contact 45, and the third contact 46 of the second battery housing section 32b.

[0075] In the above embodiments (e.g., FIG. 16 and the third embodiment), an example has been described in which the first contact 44 and the second contact 45 of the second battery housing section 32b, to which the small battery SB is connected, are independent, but this is not limited to this. The first contact 44 and the second contact 45 may be configured as a common contact. In this case, the third contact 46 of the second battery housing section 32b, to which the large battery LB is connected, may also be configured as this common contact. FIG. 21 is a diagram showing an example in which the first contact 44, the second contact 45, and the third contact 46 are configured as a common contact 47. As shown in FIG. 21A, terminals 36 of multiple small batteries SB can be connected to the common contact 47. Furthermore, as shown in FIG. 21B, the terminal 40 of the large battery LB can be connected to the common contact 47.

[0076] In one embodiment, the common contact 47 is a rail-shaped contact that extends along the direction in which the small batteries SB are arranged (the x-axis direction in the example of FIG. 21). When the common contact 47 is rail-shaped, the common contact 47 may include a positive rail and a negative rail that is arranged parallel to the positive rail. The positive electrode portions of the terminal 36 of the small battery SB and the terminal 40 of the large battery LB can be connected to the positive electrode rail. The negative electrode portions of the terminal 36 of the small battery SB and the terminal 40 of the large battery LB can be connected to the negative electrode rail.

[0077] When the common contact 47 is rail-shaped, the common contact 47 can be configured so that at least one of the terminal 36 of the small battery SB and the terminal 40 of the large battery LB can be connected to any position along the x-axis direction. In other words, the passenger can freely select, for example, whether to connect the small battery SB to a position closer to the positive x-axis direction of the common contact 47, a position near the center of the x-axis direction, or a position closer to the negative x-axis direction.

[0078] In the above embodiment, the vehicle 1 has been described as being primarily an electric motorcycle, but is not limited to this. The vehicle 1 may be, for example, an electric car, an electric two-wheeled vehicle, an electric three-wheeled vehicle, an electric bicycle, or a vehicle that is configured to be switchable between at least two of these.

[0079] In the above embodiment, the control system 42 is described as being provided in the vehicle 1, but this is not limited to this. The control system 42 may be an external information processing device (for example, a server device), and in that case, the vehicle 1 may control the operation of the motor 31 by communicating with the control system 42, which is the external information processing device.
