Description

  The present invention relates to a straddle-type electric vehicle that is charged using a charging cable.

  An example of a straddle-type electric vehicle driven by an electric motor is an electric motorcycle. The electric motor is rotated by being supplied with electric power from a battery mounted on the electric motorcycle, and the electric motorcycle can travel (see, for example, Patent Document 1). An example of a straddle-type electric vehicle is a battery-assisted bicycle. In a battery-assisted bicycle, an auxiliary power obtained by multiplying a pedal force applied to a pedal by a predetermined assist ratio is generated in an electric motor, and a resultant force of the pedal force and the auxiliary power is transmitted to driving wheels to assist driving. In the battery-assisted bicycle, by assisting human power with an electric motor supplied with power from a battery, for example, it is possible to reduce the burden on the occupant when traveling on a slope or loading luggage.

  As a method of charging the battery mounted on the electric motorcycle as described above, a method of supplying electric power from a charging station (also referred to as a charging stand) to the battery in the electric motorcycle via a charging cable is conceivable. In such a charging system, there are a mode in which the charging cable is provided on the power feeding side (charging station side) and a mode in which the charging cable is provided on the power receiving side (vehicle side).

  In the former case, since the charging cable is provided on the charging station side, it is only necessary to provide an inlet in the vehicle body, and there is no need to store the charging cable on the vehicle side. However, in the latter case, it is necessary to store the charging cable on the vehicle side. Patent Literature 1 discloses that a charging cable that is fixed to the battery side and extends from the battery side is wound around and stored inside the exterior cover of the electric motorcycle. However, electrical equipment necessary for the vehicle is disposed inside the exterior cover, and a storage box and the like are also disposed. Therefore, when it is going to store the charging cable extended from the battery side, there exists a subject that the layout of those electrical equipments, a storage box, etc. will be affected. Also, if you attempt to store the charging cable by wrapping it inside the exterior cover away from the battery, it will be necessary to run the charging cable from the battery to that position, affecting the layout of other devices. become. Moreover, in the form of a bicycle, since such an exterior cover is not provided, there is a problem that a charging cable cannot be laid out inside the exterior cover.

  The present invention provides a straddle-type electric vehicle that can suitably store a charging cable.

  A straddle-type electric vehicle according to an embodiment of the present invention includes a front wheel and a rear wheel, an electric motor that transmits a driving force to at least one of the front wheel and the rear wheel, a battery that supplies electric power to the electric motor, A charging cable used for charging the battery; an inlet that electrically connects the charging cable and the battery when the battery is charged; and a storage unit that stores the charging cable. The cable can be attached to and detached from the inlet, and the charging cable is housed in the housing portion in a state where it is removed from the inlet. Since the charging cable can be stored separately from the battery, the degree of freedom in the storage position of the charging cable can be improved.

  In one embodiment, the straddle-type electric vehicle may further include a seat on which an occupant sits, and the storage portion and the inlet may be positioned below the seat surface of the seat. Thereby, the connection between the charging cable and the inlet can be easily performed while ensuring the degree of freedom of the storage position of the charging cable. For example, the charging cable is housed on the back side of the seat or below the seat, and the inlet is positioned in the vicinity of the seat, so that the charging cable and the inlet can be easily connected.

  In one embodiment, the storage portion may be provided at a position different from the inlet in the straddle-type electric vehicle. By separating the charging cable from the inlet, the degree of freedom of the storage position of the charging cable can be improved. For example, since the charging cable can be stored at a position away from the inlet and the battery, the degree of freedom of the charging cable storage position can be improved.

  In one embodiment, the inlet may be connected to an external charging cable provided in an external charging device. Thereby, the battery can be charged even in a system in which charging is performed using a charging cable provided in an external charging device such as a charging station. That is, the battery can be charged in both of the form in which the charging cable is provided on the charging station side and the form in which the charging cable is provided on the saddle riding type electric vehicle side.

  In one embodiment, a part other than both ends of the charging cable may be connected to a part of the straddle-type electric vehicle both when the battery is charged and when the charging cable is stored. Since the charging cable is not completely separated from the saddle riding type electric vehicle, loss of the charging cable can be prevented.

  In one embodiment, the charging cable separated from the inlet may be usable as a wire lock. Thereby, the added value of the charging cable provided on the saddle riding type electric vehicle side can be improved.

  In one embodiment, the straddle-type electric vehicle is locked when charging is started, and may not be able to travel until the locked state is released. Thereby, the theft of the saddle riding type electric vehicle can be prevented. For example, by preventing the electric motor from rotating in the locked state, it is possible to prevent the saddle riding type electric vehicle from being stolen.

  In one embodiment, the lock state may be released when a password is input to the operation panel of the saddle riding type electric vehicle. Thereby, the theft of the saddle riding type electric vehicle can be prevented.

  In one embodiment, the straddle-type electric vehicle further includes a dummy socket connected to the charging cable when the charging cable is stored, and when the charging cable is not connected to the dummy socket, The saddle riding type electric vehicle may be in a restriction mode state in which traveling is restricted. Thereby, misplacement of the charging cable can be prevented.

  In one embodiment, the charging cable may include a plug connected to an external charging device during charging, and the plug may be separable from the charging cable. Even when the size of the plug is large, the charging cable and the plug can be separated from each other, whereby the degree of freedom in the storage position of the charging cable and the plug can be improved.

  In one embodiment, the vehicle further includes a front car at least a portion of which is positioned forward of a head pipe of a body frame of the saddle riding type electric vehicle, and the storage portion is closer to the front car in front of the head pipe. May be arranged. By storing the charging cable close to the front car in front of the electric vehicle, there is no need to leave a space behind the center of the electric vehicle where the battery, electric motor and drive system are arranged for the charging cable. Therefore, the freedom degree of arrangement | positioning of the component of an electric vehicle can be improved. In addition, in both models in which the charging cable is provided on the electric vehicle side and in a model that does not have the charging cable, it is not necessary to change the arrangement of the rear components from the center of the vehicle, and a common configuration can be adopted.

  In one embodiment, at least a part of the storage portion may be disposed between the head pipe and the front case. Thereby, the external appearance of the saddle riding type electric vehicle in which the charging cable is housed can be made clear.

  In one embodiment, at least a part of the storage portion may be disposed between the front cage and the front wheel. Thereby, the external appearance of the saddle riding type electric vehicle in which the charging cable is housed can be made clear.

  In one embodiment, at least a part of the storage portion may be disposed between the head pipe and the front car, and between the front car and the front wheel. Thereby, the external appearance of the saddle riding type electric vehicle in which the charging cable is housed can be made clear.

  In one embodiment, the front car may have a region for placing a load, and the storage portion may be provided on an outer peripheral side of the region for placing the load. Thereby, the external appearance of the saddle riding type electric vehicle in which the charging cable is housed can be made clear.

  According to the saddle riding type electric vehicle according to the embodiment of the present invention, since the charging cable can be stored separately from the battery, the degree of freedom of the storage position of the charging cable can be improved.

  A storage box 19 for storing a passenger's helmet and luggage is provided below the seat 27. In the vicinity of the handle 14, a display unit 71 for displaying various information such as a traveling speed, a remaining battery level, and an operation mode is provided.

  A drive unit including a controller 52 and the like and an inlet 57 to which the charging cable 31 is connected are provided near the center of the vehicle. The controller 52 controls the operation of the electric motorcycle 1. For example, the controller 52 controls the operation of the electric motor 53, controls the charging of the battery 56, and the like. The battery 56 has a configuration in which, for example, a positive line, a negative line, and a communication line extend from a battery pack that stores a plurality of cells. These positive line, negative line, and signal communication line are connected to the inlet 57 via the controller 52. When charging the battery 56, the charging cable 31 is connected to the inlet 57, and the charging cable 31 and the battery 56 are electrically connected.

  The seat 27 of the present embodiment is an openable seat, and FIG. 2 shows the electric motorcycle 1 with the seat 27 opened. A hinge 27b (FIG. 3) is provided between the seat 27 and the vehicle body 10, and the seat 27 can be opened and closed. By opening the seat 27, the occupant can take in and out the luggage with respect to the storage box 19.

  FIG. 3 is a view showing the back side of the seat 27 (the side opposite to the seating surface 27a side of the seat 27). In this example, the back side portion of the seat 27 serves as a storage portion 41 that stores the charging cable 31. For example, a plurality of hooks 27f are provided on the back side portion of the seat 27, and the charging cable 31 is wound and stored along each hook 27f. The hook 27f is, for example, an L-shaped hook.

  FIG. 4 is a diagram showing a state of charging of the electric motorcycle 1. The charging station 2 is installed in a bicycle parking lot, for example. The user takes out the charging cable 31 stored in the storage unit 41 on the back side of the seat 27 to the outside. A plug 32 is provided at one end of the charging cable 31, and a connector 34 is provided at the other end. By inserting the connector 34 into the inlet 57 of the electric motorcycle 1 and inserting the plug 32 into the socket 61 of the charging station 2, electric power is supplied from the charging station 2 to the battery 56 of the electric motorcycle 1 through the charging cable 31. Is charged. Charging control can be performed by transmitting and receiving data related to charging between the charging station 2 and the controller 52 of the electric motorcycle 1.

  5A is a diagram showing the shapes of the plug 32 and the connector 34 of the charging cable 31, and FIG. 5B is a diagram showing the shapes of the inlet 57 of the electric motorcycle 1 and the socket 61 of the charging station 2. It is. In the example of FIG. 5, the plug 32 and the connector 34 have the same shape, and the inlet 57 and the socket 61 have the same shape. However, the plug 32 and the connector 61 may have different shapes, and may have different sizes. May be different.

  The plug 32 and the connector 34 have electrode terminals 33a and 33b to which a charging voltage is supplied and a signal terminal 33c that transmits and receives data related to charging. A plurality of electrodes may be provided on the signal terminal 33c depending on the form of data to be transmitted and received. The electrode terminals 33a and 33b and the signal terminal 33c of the plug 32 are inserted into the electrode terminals 63a and 63b and the signal terminal 63c of the socket 61, respectively. The electrode terminals 33a and 33b and the signal terminal 33c of the connector 34 are inserted into the electrode terminals 63a and 63b and the signal terminal 63c of the inlet 57, respectively. Charging is performed by connecting in this way.

  The inlet 57 and the socket 61 have a cover 65. By covering each terminal with the cover 65 except during charging, intrusion of rain and dust and electric leakage can be prevented. Also, a cover may be provided on the plug 32 and the connector 34 of the charging cable 31.

  The plug 32, the connector 34, the inlet 57, and the socket 61 may have any shape and type of terminal, and the shape and the type of terminal corresponding to the form of charging are adopted. Data transmission / reception may be performed by wireless communication (for example, short-range wireless communication).

  In the form in which the electric motorcycle 1 is equipped with the charging cable 31, the charging cable 31 is detachable from the charging station 2, but in this embodiment, the charging cable 31 is also connected to the inlet 57. The charging cable 31 is stored in the storage unit 41 on the back side of the seat 27 in a state where it is detached from the inlet 57.

  Thus, in this embodiment, since the charging cable 31 can be stored separately from the battery 56, the degree of freedom of the storage position of the charging cable 31 can be improved. For example, it becomes easy to store the charging cable 31 in the back side portion of the seat 27 as described above. Since it is not necessary to leave a space in which the drive unit, the various drive mechanisms, the storage box, and the like of the electric motorcycle 1 are disposed for storing the charging cable 31, the degree of freedom in arranging the components of the electric motorcycle 1 is increased. Can be improved. Further, it is not necessary to make the arrangement of the drive unit and various drive mechanisms different in both models including and not including the charging cable 31 on the vehicle side, and a common configuration can be adopted.

  In the above example, the storage portion 41 and the inlet 57 are located below the seating surface 27 a of the seat 27. Thereby, the charging cable 31 and the inlet 57 can be easily connected while ensuring the degree of freedom of the storage position of the charging cable 31. For example, the charging cable 31 is housed on the back side of the seat 27 or below the seat 27, and the inlet 57 is positioned in the vicinity of the seat 27, so that the charging cable 31 and the inlet 57 can be easily connected.

  The form in which the storage portion 41 is provided on the back side of the seat 27 described above is an example, and the storage portion 41 may be provided at another position of the vehicle by taking advantage of the fact that the charging cable 31 is separated from the battery 56. For example, as will be described later, in the form in which the electric motorcycle 1 has a front car, the storage portion 41 may be provided in the vicinity of the front car. Since the charging cable 31 can also be stored at a position away from the battery 56 and the inlet 57, the degree of freedom of the storage position of the charging cable 31 can be improved.

  As described above, the charging system may be provided with a charging cable on the charging station 2 side. The inlet 57 of the electric motorcycle 1 may have such a shape that a charging cable provided on the charging station 2 side can be connected. In this case, the battery 56 can be used even if such a charging system is used. Can be charged.

  FIG. 6 is a diagram illustrating a state in which the electric motorcycle 1 is charged using a charging system in which a charging cable is provided on the charging station 2 side. A connector 39 is provided at the tip of the charging cable 38 provided on the charging station 2 side. The connector 34 of the charging cable 31 mounted on the electric motorcycle 1 and the connector 39 of the charging cable 38 extending from the charging station 2 have the same terminal shape. By inserting the connector 39 of the charging cable 38 into the inlet 57 of the electric motorcycle 1, electric power is supplied from the charging station 2 to the battery 56 of the electric motorcycle 1 to perform charging. Charging control can be performed by transmitting and receiving data related to charging between the charging station 2 and the controller 52 of the electric motorcycle 1.

  As described above, since the charging cable 38 can also be connected to the inlet 57, the charging of the battery 56 can be performed both in the form in which the charging cable is provided on the charging station 2 side and in the form in which the charging cable is provided on the electric motorcycle 1 side. It can be performed. For this reason, it can charge irrespective of the form of the charging station installed in a bicycle parking lot etc., and the convenience of the electric motorcycle 1 can be improved.

  Further, the inlet 57 may be disposed in the storage box 19. FIG. 7 is a view showing the electric motorcycle 1 in which the inlet 57 is disposed in the storage box 19. As described above, when the charging cable 31 is stored in the back side portion of the seat 27, the seat 27 is opened and the charging cable 31 is removed. In this case, if the inlet 57 is disposed in the storage box 19, the charging cable 31 can be removed and immediately connected to the inlet 57, so that the amount of work for the user can be reduced and convenience can be improved. Further, when the charging cable 31 is stored, the charging cable 31 can be stored immediately after being removed from the inlet 57.

  When the inlet 57 is provided in the storage box 19, a gap such as a groove shape is provided in the vicinity of the seat 27 of the vehicle body 10 or in the seat 27 to provide a communication path between the inside and the outside of the storage box 19. The charging station 2 may be connected through 31. Thereby, the sheet | seat 27 can be closed and locked during charge.

  A part other than both ends of the charging cable 31 may be connected to a part of the electric motorcycle 1 both when the battery 56 is charged and when the charging cable 31 is stored. FIG. 8 is a diagram showing the electric motorcycle 1 in which a part of the charging cable 31 is always connected. In the example of FIG. 8, a part of the charging cable 31 is connected to a fastener 27 c provided on the back side of the seat 27. The shape of the fastener 27c is arbitrary. For example, the fastener 27c may have an annular portion, and the charging cable 31 may be passed through the annular portion. Further, a part of the charging cable 31 may be fixed to the back side of the seat 27 by the fastener 27c. Even when both the plug 32 and the connector 34 of the charging cable 31 are released, the charging cable 31 is not completely separated from the electric motorcycle 1, so that the charging cable 31 can be prevented from being lost. The position of the vehicle to which a part of the charging cable 31 is connected is arbitrary, but the charging cable 31 can be easily stored by connecting the charging cable 31 in the vicinity of the storage unit 41.

  Further, a dummy socket may be provided in the storage unit 41, and the plug 32 and the connector 34 of the charging cable 31 may be connected to such a dummy socket during storage. FIG. 9 is a view showing the storage portion 41 in which the dummy socket 35 is provided. The plug 32 and the connector 34 are fixed by inserting the plug 32 and the connector 34 of the charging cable 31 into the dummy socket 35. Thereby, the plug 32 and the connector 34 can be stably held while the electric motorcycle 1 is traveling. In the example of FIG. 9, both the plug 32 and the connector 34 are connected to the dummy socket 35, but the dummy socket 35 may be configured to connect only one of them. Further, the dummy socket 35 for connecting the plug 32 and the dummy socket 35 for connecting the connector 34 may be provided separately.

  The plug 32 and the connector 34 may be separable from the charging cable 31. FIG. 10 is a diagram showing a charging cable 31 in which the plug 32 and the connector 34 can be separated. For example, the size of the plug 32 of the charging cable 31 may be large in accordance with the size of the socket 61 (FIG. 5B) of the charging station 2. In such a case, the degree of freedom of arrangement of the charging cable 31 and the plug 32 can be improved by separating the plug 32 from the charging cable 31 and storing the plug 32 in different positions.

  In addition, when the electric motorcycle 1 is made to correspond to a charging system in which the charging cable 38 as shown in FIG. 6 is provided on the charging station 2 side, the inlet 57 of the electric motorcycle 1 has the size of the connector 39 of the charging cable 38. In some cases, it may be large. In this case, since the connector 34 of the charging cable 31 is also large, the charging cable 31 and the connector 34 can be arranged by separating the connector 34 from the charging cable 31 and storing the connectors 34 in different positions. The degree of freedom can be improved.

  In the example of FIG. 10, small plugs 36 are provided at both ends of the charging cable 31, and small sockets 37 are provided inside the plug 32 and the connector 34. By connecting the small plug 36 and the small socket 37, the plug 32 and the connector 34 and the charging cable 31 are connected. By separating the small plug 36 and the small socket 37, the plug 32 and the connector 34 and the charging cable 31 are charged. The cable 31 is separated.

  FIG. 11 is a diagram illustrating an arrangement example of the separated plug 32, connector 34, and charging cable 31. In this example, the charging cable 31 is accommodated along the vicinity of the outer peripheral portion on the back side of the seat 27, and the plug 32 and the connector 34 are accommodated near the center portion on the back side of the seat 27. As described above, the plug 32 and the connector 34 are separated from the charging cable 31 and stored in different positions, so that the degree of freedom of arrangement of the plug 32, the connector 34 and the charging cable 31 can be improved. In this example, the plug 32 and the connector 34 and the charging cable 31 are housed on the back side of the seat 27. However, the plug 32 and the connector 34 may be housed in another position away from the charging cable 31. Good. For example, the plug 32 and the connector 34 may be accommodated in an arbitrary position from the vehicle central portion to the front portion, or may be accommodated in the vehicle rear portion. In the above example, both the plug 32 and the connector 34 are separable from the charging cable 31, but only one of them may be separable.

  The charging cable 31 may be used as a wire lock. FIG. 12 is a diagram showing a charging cable 31 that can also be used as a wire lock. In this example, the plug 32 of the charging cable 31 is provided with a lock portion 32L, and the connector 34 is provided with a lock portion 34L. The lock part 34L is locked by being inserted into the lock part 32L. Unlocking may be performed by operating the dial 32D of the lock portion 32L, or a key may be used.

  In the above description, the electric motorcycle 1 is exemplified as the straddle-type electric vehicle according to the embodiment of the present invention. However, the above-described embodiment can also be applied to a battery-assisted bicycle.

  FIG. 13 shows a two-wheel battery-assisted bicycle 3 as an example of a straddle-type electric vehicle according to an embodiment of the present invention. The battery-assisted bicycle 3 travels by generating, in an electric motor, auxiliary power obtained by multiplying a pedal force applied to a pedal by a predetermined assist ratio in an electric motor, and transmitting the resultant force of the pedal force and the auxiliary power to driving wheels. As the battery-assisted bicycle 3, there are a form in which the electric motor does not generate power unless the pedal is lifted, and a form in which the electric motor can generate power and travel without the pedal being pushed. Applicable to both forms.

  The battery-assisted bicycle 3 has a vehicle body frame 11 extending in the front-rear direction. A head pipe 12 is provided at the front end of the body frame 11. The handle stem 13 is rotatably inserted into the head pipe 12. The handle 14 is fixed to the upper end portion of the handle stem 13. A front fork 15 is fixed to the lower end portion of the handle stem 13. A front wheel 25 that is a steering wheel is rotatably supported at the lower end of the front fork 15. A front car 21 is provided at a position in front of the head pipe 12.

  A saddle tube 16 extends upward from near the center of the vehicle body frame 11. A saddle pipe 17 is inserted into the saddle tube 16, and a seat (saddle) 27 on which an occupant sits is provided at the upper end of the saddle pipe 17. In the rear part of the vehicle body frame 11, a rear wheel 26 that is a driving wheel is rotatably supported. Further, a stand 29 is provided at the rear portion of the body frame 11 to hold the vehicle upright when parking.

  A drive unit 51 is provided near the center of the vehicle body frame 11. The drive unit 51 includes a controller 52, an electric motor 53, a crank 54, and a pedal 55. The drive unit 51 is equipped with a battery 56 that supplies electric power to the electric motor 53 and the like.

  The controller 52 controls the operation of the battery-assisted bicycle 3. The pedal effort applied to the crank 54 when the occupant rotates the pedal 55 is transmitted to the rear wheel 26 via the chain 28. The controller 52 controls an assist ratio that is a ratio of the occupant's pedaling force and auxiliary power, and the electric motor 53 generates a driving force according to the pedaling force and the assist ratio. The driving force output from the electric motor 53 is transmitted to the rear wheel 26 via the chain 28. In this way, the pedaling force of the occupant and the driving force of the electric motor 53 are added together and become the power of the battery-assisted bicycle 3. In place of the chain 28, a belt, a shaft, or the like may be used.

  The battery-assisted bicycle 3 of this embodiment is equipped with a charging cable 31 used for charging the battery 56. The battery 56 is charged using a charging system that supplies power to the battery 56 in the battery-assisted bicycle 3 from the charging station 2 (FIG. 15) via the charging cable 31. When charging is not performed, the charging cable 31 is stored in the battery-assisted bicycle 3. In the example of FIG. 13, when the charging cable 31 is stored, the charging cable 31 is disposed in front of the head pipe 12 and in proximity to the front car 21. For example, the storage portion 41 is disposed between the head pipe 12 and the front car 21, and the charging cable 31 is stored in the storage portion 41.

  FIG. 14A is a view of the storage unit 41 as viewed from the side surface of the battery-assisted bicycle 3, and the interior of the storage unit 41 is shown in a transparent manner for easy understanding. The storage portion 41 is disposed in front of the head pipe 12 and close to the rear side of the front car 21. The storage part 41 may be fixed to at least one of the head pipe 12 and the front car 21 or may be detachable.

The storage unit 41 has, for example, a box shape along the side surface shape behind the front car 21. The charging cable 31 is accommodated in the box shape. The storage unit 41 may be a hard case type or a soft case type. Moreover, a bag type may be sufficient.

  FIG. 14B is a view of the storage unit 41 as viewed from the front of the battery-assisted bicycle 3, and shows the interior of the storage unit 41 in a transparent manner for easy understanding. In the example of FIG. 14, the charging cable 31 is stored in the storage unit 41 in a meandering state. Here, the meandering state refers to a state in which the charging cable 31 is folded back at least once. By causing the charging cable 31 to meander, the arrangement along the side shape of the front car 21 can be facilitated.

  In the present embodiment, the charging cable 31 is disposed close to the front car 21 in front of the vehicle. Since it is not necessary to leave a space behind the center of the vehicle where the drive unit 51 including the electric motor 53 and the battery 56 and various drive mechanisms are arranged for storing the charging cable 31, the configuration of the battery-assisted bicycle 3. The degree of freedom of element arrangement can be improved. In addition, by arranging the charging cable 31 along the shape of the front car 21, it is easy to secure a space for arranging the charging cable 31. Further, in both models including the model provided with the charging cable 31 on the vehicle side and the model not provided with the vehicle side, it is not necessary to change the arrangement of the rear components from the center of the vehicle, and a common configuration can be adopted.

  Further, by storing the charging cable 31 between the head pipe 12 and the front car 21, the exterior of the battery-assisted bicycle 3 equipped with the charging cable 31 can be made clear.

  Further, as shown in FIGS. 14A and 14B, the height of the upper end of the storage portion 41 may be made lower than the height of the upper end of the front car 21. Further, the width in the left-right direction of the storage portion 41 may be smaller than the width in the left-right direction of the front car 21. As a result, the appearance of the battery-assisted bicycle 3 equipped with the charging cable 31 can be made clear, and the appearance around the front car 21 as seen from the occupant can also be made clear.

  In this example, an inlet 57 to which the charging cable 31 is connected is provided on the saddle tube 16 near the center of the vehicle. When charging the battery 56, the charging cable 31 is connected to the inlet 57, and the charging cable 31 and the battery 56 are electrically connected. The arrangement position of the inlet 57 is arbitrary, and may be arranged, for example, in the drive unit 51.

  FIG. 15 is a diagram showing how the battery-assisted bicycle 3 is charged. The charging station 2 shown in FIG. 15 has, for example, the same configuration as the charging station 2 shown in FIG. 4, and supports charging of the batteries 56 of both the electric motorcycle 1 and the battery-assisted bicycle 3.

  The user takes out the charging cable 31 stored in the storage portion 41 near the front car 21 to the outside. The charging cable 31 mounted on the battery-assisted bicycle 3 has the same configuration as the charging cable 31 mounted on the electric motorcycle 1. A plug 32 is provided at one end of the charging cable 31, and a connector 34 is provided at the other end. By inserting the connector 34 into the inlet 57 of the battery-assisted bicycle 3 and inserting the plug 32 into the socket 61 of the charging station 2, electric power is supplied from the charging station 2 to the battery 56 of the battery-assisted bicycle 3 via the charging cable 31. It is supplied and charged. Charging control can be performed by transmitting and receiving data related to charging between the charging station 2 and the controller 52 of the battery-assisted bicycle 3.

  The direction in which the charging cable 31 is taken in and out of the storage unit 41 is arbitrary, and the charging cable 31 may be taken in or out from the side of the storage unit 41 or from the top of the storage unit 41. A portion of the storage portion 41 where the charging cable 31 is taken in and out may be provided with a lid or a fastener such as a fastener.

  Next, operation processing and charging processing of the saddle riding type electric vehicle according to the embodiment of the present invention will be described. In the following description, processing in the electric motorcycle 1 is exemplified, but the same components and processing can be applied to the battery-assisted bicycle 3 as well.

  FIG. 26 is a block diagram showing components of the charging station 2 and the electric motorcycle 1. The electric motorcycle 1 includes a determination unit 81, a motor control unit 82, a battery control unit 83, a connection detection unit 84, and a data transmission / reception unit 85. The controller 52 may be responsible for at least some functions of the determination unit 81, the motor control unit 82, the battery control unit 83, the connection detection unit 84, and the data transmission / reception unit 85. A display unit 71 provided in the vicinity of the handle 14 displays a traveling speed, a remaining battery level, a traveling mode, a charging state, and the like. The user input unit 73 is provided adjacent to the display unit 71, for example, and accepts various inputs from the user. The display unit 71 and the user input unit 73 can also be provided in the battery-assisted bicycle 3. The user input unit 73 may be configured by arranging a plurality of physical buttons, or may be a touch panel. In the case of a touch panel, the user input unit 73 may be formed integrally with the display unit 71. Further, the user input unit 73 may accept various inputs by voice input, gesture input, or the like.

  The determination unit 81 makes determinations in various processes and controls the entire various processes. Information on the amount of motor operation corresponding to the amount of throttle operation of the electric motorcycle 1 and the pedal effort of the battery-assisted bicycle 3 is input to the motor control unit 82. Further, information on the maximum allowable driving force is input from the determination unit 81 to the motor control unit 82. The motor control unit 82 controls the operation of the electric motor 53 according to these pieces of information.

  The battery control unit 83 receives information on whether charging is possible from the determination unit 81 and charges the battery 56. The connection detection unit 84 detects the connection of the plug 32 and the connector 34 of the charging cable 31 to the dummy socket 35 (FIGS. 9 and 23) and outputs the detection result to the determination unit 81. The data transmission / reception unit 85 performs data communication between the charging station 2 and the determination unit 81 and transmits / receives various data (such as the status of the charging station 2 and the electric motorcycle 1).

  The charging station 2 includes a determination unit 91, a charging power output unit 93, and a data transmission / reception unit 95. The determination unit 91 makes determinations in various processes and controls the entire various processes. The charging power output unit 93 outputs and stops charging power in response to an instruction from the determination unit 91. The data transmission / reception unit 95 performs data communication between the determination unit 91 and the electric motorcycle 1 and transmits / receives various data (such as the status of the charging station 2 and the electric motorcycle 1).

  FIG. 27 is a flowchart showing an operation process of the electric motorcycle 1. When the power of the electric motorcycle 1 is turned on, the user inputs a password from the user input unit 73. The determination unit 81 determines whether or not the password matches the correct password (step S10). If the passwords do not match, the electric motorcycle 1 is not started. When the passwords match, the determination unit 81 determines whether or not the connection of the plug 32 and the connector 34 of the charging cable 31 to the dummy socket 35 is detected (step S11). If the connection is not detected, the charging cable 31 may not be stored correctly, so the vehicle mode is set to a limiting mode that limits the speed to a predetermined value or less (step S13). When the connection is detected, it is determined that the charging cable 31 is stored correctly, and the vehicle mode is set to the normal mode (step S12). If the connection to the dummy socket 35 is not detected, the charging mode 31 can be prevented from being left behind by setting the restriction mode.

  Next, the determination unit 81 determines whether the plug 32 of the charging cable 31 is connected to the charging station 2 and the connector 34 is connected to the inlet 57 (step S14). If it is connected, a charging process is performed (step S15). If not connected, other processing (for example, processing according to the vehicle mode at that time) is performed, and the process proceeds to step S16. Next, the determination unit 81 determines whether or not the user has performed an operation for terminating the system (step S16). If the system termination operation has not been performed, the processing from steps S11 to S16 is repeated. When an operation for terminating the system is performed, the electric motorcycle 1 is turned off.

  FIG. 28 is a flowchart showing details of the charging process in step S15. Charging is started after the motor control unit 82 stops the operation of the electric motor 53 in response to an instruction from the determination unit 81 (step S21). Determination unit 81 determines whether data is received from charging station 2 (step S22). If no data is received for a predetermined period, it is determined that charging cannot be performed normally, the vehicle mode is set to “charger abnormality mode”, and “charger abnormality” is displayed on the display unit 71 (steps S24 and S24). S25). Then, the process proceeds to step S30.

  In step S22, when data is received from charging station 2, the content of the received data is analyzed (step S23). When the received data content indicates charging abnormality, charging is interrupted, the vehicle mode is set to “charger abnormality”, and “charger abnormality” is displayed on the display unit 71 (steps S24 and S25). Then, the process proceeds to step S30.

  In step S23, if the content of the received data indicates that charging has ended normally, the vehicle mode is set to “normal charging end”, and “normal charging end” is displayed on the display unit 71 (steps S26 and S27). ). Then, the process proceeds to step S30.

  In step S23, when the content of the received data indicates that charging is in progress, the vehicle mode is maintained as “charging”, and it is confirmed whether there is an instruction to stop charging from the user (step S29). If there is no charge stop instruction, the process returns to step S22. If there is an instruction to stop charging, the process proceeds to step S30.

  In step S <b> 30, the user inputs a password from the user input unit 73. The determination unit 81 determines whether or not the password matches the correct password. If the passwords do not match, the user does not start the electric motorcycle 1 and asks the user to re-enter the password. If the passwords match, the vehicle mode is set to the normal mode (step S31). Then, the process proceeds to the process of step S16 in FIG. 27, and when the system termination operation is not performed, the processes of steps S11 to S16 are repeated. When an operation for terminating the system is performed, the electric motorcycle 1 is turned off.

  In addition, the electric motorcycle 1 may be controlled so that it is locked when charging is started and cannot travel until the locked state is released. Thereby, the theft of the electric motorcycle 1 can be prevented. For example, it is possible to prevent the electric motorcycle 1 from being stolen by preventing the electric motor 53 from rotating in the locked state. The lock state can be released by inputting a password. Note that a biometric authentication system such as fingerprint authentication or a wireless communication system such as a keyless entry system may be used instead of such password input and password input in steps S10 and S30 in FIGS. It may be used.

  In the above-described embodiment, the charging cable 31 may have a curl cord shape (spiral shape) having elasticity. For example, since at least a part of the charging cable 31 has a curled cord shape, the space required for storage can be reduced.

  Further, the storage unit 41 may be labeled to indicate that it is the storage unit 41 and the storage method. Thereby, the user can easily recognize the position of the storage unit 41 and the storage method.

  Moreover, a lighting part may be provided in the plug 32, the connector 34, the inlet 57, etc., and the charging operation status may be notified to the user by the lighting state. As a result, the user can easily recognize the charging operation status.

  In addition, as described above, the battery 56 may have a configuration in which a positive line, a negative line, and a communication line extend from a battery pack that stores a plurality of cells. The above-described saddle riding type electric vehicle does not have the inlet 57, and the charging cable 31 may be directly connected to the positive electrode line, the negative electrode line, and the signal communication line. In this case, control of charging may be performed by a control circuit in the battery pack. Separating the charging cable 31 from the battery 56 may mean separating the charging cable 31 from the inlet 57, or may mean separating the charging cable 31 and the wiring extending from the battery pack. Good.

  In the above description, the driving wheel to which the driving force of the electric motor is transmitted is the rear wheel 26. However, the driving force of the electric motor is transmitted to the front wheel 25 according to the form of the saddle riding type electric vehicle. Also good. Further, the driving force may be transmitted to both the front wheel 25 and the rear wheel 26.

  The embodiments of the present invention have been described above. The above description of the embodiment is an exemplification of the present invention and does not limit the present invention. In addition, an embodiment in which the components described in the above embodiment are appropriately combined is possible. The present invention can be modified, replaced, added and omitted within the scope of the claims and the equivalents thereof.

  The present invention is particularly useful in the field of straddle-type electric vehicles that are charged using a charging cable.
