Summary of the Invention

Problems to be Solved by the Invention

[0004] During the battery replacement operation by the battery replacement system disclosed in Patent Document 1, a situation may occur where it is necessary to evacuate the electric vehicle from the battery replacement station due to external factors such as disasters. However, if the battery replacement is not completed, the electric vehicle cannot self-drive and cannot evacuate from the battery replacement station.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide an electric vehicle capable of self-driving even without power supply from a battery to a vehicle drive unit 11 of the electric vehicle.

Means for Solving the Problems

[0006] The electric vehicle of the present disclosure includes a first battery, a drive unit, and an auxiliary battery configured to be able to supply power to the drive unit. The first battery mounted on the electric vehicle can be replaced with a second battery by a battery exchange station provided outside the electric vehicle. The electric vehicle can drive the drive unit by supplying power from the auxiliary battery to the drive unit.

[0007] According to the above configuration, the electric vehicle can drive the drive unit by the auxiliary battery. Thereby, even if there is no power supply from the first battery or the second battery to the drive unit, the electric vehicle can run on its own.

[0008] The above electric vehicle further includes a control unit, an input device operated by a user, and a switching device that switches the electrical connection between the first battery or the second battery and the drive unit. When the control unit determines that an input indicating starting from the user is input to the input device during the period from the start to the end of the replacement of the first battery by the battery exchange station, the control unit causes the switching device to disconnect the electrical connection and supply power from the auxiliary battery to the drive unit.

[0009] By configuring in this way, it is possible to start supplying power from the auxiliary battery to the drive unit due to an input indicating starting from the user.

[0010] In the above electric vehicle, the input device includes a display unit and an input unit operated by a user. After being replaced with the second battery by the battery exchange station, when the control unit determines that there is an abnormality in the second battery, the control unit displays a first inquiry display asking the user whether to start on the display unit.

[0011] By configuring in this way, when an abnormality occurs in the battery after replacement, it is possible to start supplying power from the auxiliary battery or to ask for the user's judgment.

[0012] In the above electric vehicle, the input device includes a display unit and an input unit operated by a user. When the control unit receives a system abnormality signal from the battery exchange station, it displays a second inquiry display on the display unit to inquire of the user whether to start.

[0013] By configuring in this way, when there is a system abnormality from the battery exchange station, it is possible to ask for the user's judgment on whether to start the power supply from the auxiliary battery.

[0014] In the above electric vehicle, when the control unit determines that an input indicating that the user wants to start has been input to the input device, it transmits a start signal to the battery exchange station. When the battery exchange station receives the start signal, after making the electric vehicle in a startable state, it transmits a startable signal to the electric vehicle. When the control unit receives the startable signal, it causes the power from the auxiliary battery to be supplied to the drive unit.

[0015] By configuring in this way, even when the electric vehicle is in a state of being restricted by the battery exchange station, due to a signal from the electric vehicle, the battery exchange station releases the restriction of the electric vehicle and makes the electric vehicle transmissible.

Effect of the Invention

[0016] According to the present disclosure, it is possible to provide an electric vehicle that can run on its own even without power supply from a battery to the vehicle drive unit of the electric vehicle.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their description will not be repeated.

[0019] <Configuration of Battery Exchange System> FIG. 1 is a diagram showing a battery exchange system including an electric vehicle according to the present embodiment. Note that the Z direction shown in the figure indicates the moving direction of the battery mounting table 231 described later.

[0020] Referring to FIG. 1, this battery exchange system 1 includes an electric vehicle 100 and a battery exchange station 200.

[0021] The electric vehicle 100 includes a communication device 17 and a battery 101. The communication device 17 is formed to be communicable with the battery exchange station 200. The electric vehicle 100 is, for example, a battery electric vehicle (BEV) that does not include an internal combustion engine. Note that the battery 101 is an example of the "first battery" of the present disclosure.

[0022] The battery replacement station 200 includes a battery replacement station main body 200a where battery replacement is performed, and a storage 200b in which at least one battery 201 is stored. The battery replacement station main body 200a is a device that performs battery replacement for replacing the battery 101 mounted on the electric vehicle 100 with the battery 201. The storage 200b is provided adjacent to the battery replacement station main body 200a. An entrance / exit 202 for the electric vehicle 100 to enter and exit is provided in the battery replacement station 200 (battery replacement station main body 200a). Note that the battery 201 is an example of the "second battery" of the present disclosure.

[0023] After the battery 201 stored in the storage 200b is moved to a temporary placement area 240 provided in the underfloor area U, it is transported to the electric vehicle 100. A drive device 230 is provided in the underfloor area U.

[0024] The battery replacement station 200 (battery replacement station main body 200a) includes a control device 210 and a drive device 230. The drive device 230 includes a battery mounting table 231, a lifting unit 232, and a transport unit 233. The drive device 230 further has various sensors (not shown) for detecting occurrence of a malfunction.

[0025] The control device 210 includes a processor 211, a memory 212, and a communication unit 213. In addition to the program executed by the processor 211, information used in the program (for example, maps, mathematical formulas, and various parameters) is stored in the memory 212. Battery information, which is information regarding the battery shape, battery arrangement direction, voltage, output power, and capacity (remaining capacity) of each battery 201, is further recorded in the memory 212. Note that the information regarding the battery arrangement direction of each battery 201 includes the position information of the connector for connecting the battery 201 to the electric vehicle 100. The processor 211 controls the drive device 230. When the processor 211 receives a signal related to a system abnormality detected by the drive device 230 or the like, it notifies the electric vehicle 100 of the system abnormality via the communication unit 213.

[0026] The communication unit 213 includes various communication I / Fs. The processor 211 controls the communication unit 213. The communication unit 213 communicates with the communication device 17 of the electric vehicle 100. Communication is possible in both directions between the communication unit 213 and the electric vehicle 100 (communication device 17). The communication unit 213 can further communicate with the mobile terminal 300 owned by the user of the electric vehicle 100. Note that this embodiment shows an example in which various information is exchanged between the communication device 17 of the electric vehicle 100 and the communication unit 213 of the battery exchange station 200.

[0027] The battery exchange station 200 is provided with a vehicle stop area 203. When an operation to instruct the start of the battery exchange operation is performed by the user on the HMI device 18 of the electric vehicle 100 shown in FIG. 2 described later while the electric vehicle 100 is stopped in the vehicle stop area 203, the communication unit 213 receives an instruction signal to start the battery exchange operation from the electric vehicle 100. Based on the communication unit 213 receiving the above instruction signal, the processor 211 starts controlling the battery exchange operation by the drive device 230.

[0028] The lifting unit 232 raises and lowers the electric vehicle 100 by holding the electric vehicle 100 from below and moving it up and down. The lifting unit 232 includes a pair of lifting bars 232a. The electric vehicle 100 is supported from below by the pair of lifting bars 232a. The battery exchange (attachment and detachment of the battery) is performed while the electric vehicle 100 is horizontally held by the pair of lifting bars 232a.

[0029] The battery mounting table 231 is configured to be able to move up and down in the Z direction. When the battery mounting table 231 rises to the height position of the bottom of the electric vehicle 100, the battery 101 removed from the electric vehicle 100 is placed on the battery mounting table 231. Also, when the battery mounting table 231 on which the battery 201 is placed rises to the height position of the bottom of the electric vehicle 100, the battery 201 is attached to the electric vehicle 100.

[0030] The conveying unit 233 is configured to be able to convey the batteries 101 and 201. Specifically, the conveying unit 233 conveys the battery 101 removed from the electric vehicle 100 and placed on the battery mounting table 231 to the temporary storage place 240. Further, the conveying unit 233 conveys the battery 201 conveyed from the storage 200b to the temporary storage place 240 to the battery mounting table 231.

[0031] FIG. 2 is a diagram showing the configuration of an electric vehicle according to an embodiment of the present disclosure. With reference to FIG. 2, the details of the electric vehicle 100 will be described.

[0032] The electric vehicle 100 includes a vehicle body 10 and a battery 101.

[0033] The vehicle body 10 is a part of the electric vehicle 100 other than the battery 101. The vehicle body 10 includes a vehicle drive unit 11, an SMR 12, an auxiliary battery 13, a DC / DC converter 14, a relay 15, an EV-ECU 16, a communication device 17, an HMI device 18, and a terminal 19A. The terminal 19A is formed to be electrically connectable to a terminal 19B formed on the battery 101, and the vehicle body 10 is formed to be electrically connectable to the battery 101 via the terminals 19A and 19B. Note that the vehicle drive unit 11 is an example of the “drive unit” of the present disclosure. The SMR 12 is an example of the “switching device” of the present disclosure. The EV-ECU 16 is an example of the “control unit” of the present disclosure. The HMI device 18 is an example of the “input device” of the present disclosure.

[0034] The vehicle drive unit 11 includes an MG (Motor Generator) 11a and an inverter 11b. The vehicle drive unit 11 is configured to run the electric vehicle 100 using the electric power output from the battery 101.

[0035] The MG 11a functions as a motor for running. The MG 11a is electrically connected to the battery 101 via the inverter 11b. The MG 11a converts the electric power from the battery 101 into torque and rotates the drive wheels of the electric vehicle 100. Further, the MG 11a performs regenerative power generation, for example, when the electric vehicle 100 decelerates, and charges the battery 101.

[0036] Inverter 11b functions as a PCU (Power Control Unit) for MG11a. Inverter 11b drives MG11a using the power supplied from battery 101.

[0037] SMR12 functions as an on-off switch for the electrical circuit between inverter 11b and battery 101 according to an instruction from EV-ECU16. SMR12 is provided between inverter 11b and battery 101. Note that "SMR" means System Main Relay.

[0038] Auxiliary battery 13 supplies power for driving auxiliary devices mounted on electric vehicle 100, such as communication device 17, EV-ECU16, and HMI device 18. Also, auxiliary battery 13 is connected to the wiring that connects inverter 11b and SMR12 via DC / DC converter 14.

[0039] DC / DC converter 14 boosts the voltage of the direct current supplied from auxiliary battery 13 to MG11a and supplies it to inverter 11b. DC / DC converter 14 is provided between auxiliary battery 13 and the wiring that connects SMR12 and inverter 11b.

[0040] Relay 15 functions as an on-off switch for the electrical circuit between auxiliary battery 13 and inverter 11b according to an instruction from EV-ECU16. Relay 15 is provided between DC / DC converter 14 and the wiring that connects SMR12 and inverter 11b.

[0041] The EV-ECU 16 has a processor (not shown) and a memory. The processor controls each device of the electric vehicle 100 based on the information recorded in the memory and the information acquired through, for example, the communication device 17 described later. The EV-ECU 16 is communicably connected to each device (SMR 12, relay 15, communication device 17, HMI device 18, Bat-ECU 23) via an in-vehicle network (for example, CAN (Controller Area Network)). The EV-ECU 16 communicates with the communication unit 213 using the communication device 17.

[0042] The communication device 17 is an interface for communicating with devices outside the vehicle (such as the communication unit 213 and the mobile terminal 300) via a network. The communication device 17 transmits the information transmitted from the EV-ECU 16 to the devices outside the vehicle, or transmits the information received from the devices outside the vehicle to the EV-ECU 16.

[0043] The HMI device 18 includes a display unit 18a and an input unit 18b provided in the vehicle interior. The HMI device 18 may include a touch panel display. The input unit 18b may be a hard key provided adjacent to the display unit 18a, or may be operated on the touch panel display. The HMI device 18 outputs a signal corresponding to the input to the input unit 18b by the user to the EV-ECU 16.

[0044] The battery 101 includes a battery 21, an SMR 22, a Bat-ECU 23, and a terminal 19B.

[0045] The battery 21 is a secondary battery such as, for example, a lithium-ion battery, a nickel-metal hydride battery, or a sodium-ion battery. The type of the secondary battery may be a liquid secondary battery or an all-solid-state secondary battery. The battery 21 is formed to be electrically connectable to the vehicle body 10 by connecting the terminal 19A and the terminal 19B.

[0046] SMR22 functions as an on-off switch for the electrical circuit between the battery 21 and the terminal 19B in accordance with an instruction from the Bat-ECU23 described later. SMR22 is provided between the battery 21 and the terminal 19B.

[0047] Bat-ECU23 has a processor (not shown) and a memory. The processor controls SMR22 based on the information recorded in the memory and the information acquired from the EV-ECU16. Bat-ECU23 is communicably connected to the EV-ECU16 and SMR22 via an in-vehicle network (for example, CAN (Controller Area Network)). Bat-ECU23 switches the on-off switch of SMR22 based on an instruction from the EV-ECU16. Note that the configuration of the battery 201 is the same as that of the battery 101.

[0048] <Auxiliary Battery Startup Flow> Next, with reference to FIGS. 3 and 4, the auxiliary battery startup flow executed by the electric vehicle and the battery exchange station will be described.

[0049] In step S10 shown in FIG. 3, the electric vehicle 100 transmits an instruction to start the battery exchange operation to the battery exchange station 200. Specifically, in step S10, the electric vehicle 100 is arranged in the vehicle stop area 203. Thereafter, the electric vehicle 100 instructs the battery exchange station 200 to start the replacement operation of the battery 101 mounted on the electric vehicle 100 based on the user input on the HMI device 18.

[0050] In step S20, the battery exchange station 200 checks whether it has received a notification of the battery exchange operation start instruction from the electric vehicle 100. If it has received the notification of the battery exchange operation start instruction (Yes in step S20), the process of the battery exchange station 200 proceeds to step S30. If it has not received the notification of the battery exchange operation start instruction (No in step S20), the battery exchange station 200 processes step S20 again.

[0051] In step S30, the battery exchange station 200 starts the battery exchange operation. In the battery exchange operation, the electric vehicle 100 is restrained by a wheel lock (not shown). Alternatively, the electric vehicle 100 is held and restrained from below by the lifting part 232.

[0052] In step S40, the battery exchange station 200 determines whether a system abnormality in the battery exchange operation has been detected. Specifically, various sensors provided in the drive device 230 of the battery exchange station 200 detect the system abnormality and transmit a system abnormality signal to the processor 211. The processor 211 determines whether a system abnormality has occurred in the battery exchange station 200 based on the presence or absence of the signal. If a system abnormality has occurred (Yes in step S40), the process of the battery exchange station 200 proceeds to step S60. If no system abnormality has occurred (No in step S40), the process of the battery exchange station 200 proceeds to step S50.

[0053] In step S50, the battery exchange station 200 determines whether the battery exchange operation has been completed. If the operation has been completed (Yes in step S50), the battery exchange station 200 transmits a battery exchange operation completion notification to the electric vehicle 100 and completes the process (step S55). If the operation has not been completed (No in step S50), the battery exchange station 200 processes step S40 again.

[0054] In step S60, the battery exchange station 200 aborts the battery exchange operation.

[0055] In step S70, the battery exchange station 200 notifies the electric vehicle 100 that a system abnormality has occurred.

[0056] In step S80, the electric vehicle 100 checks whether it has received a battery replacement work completion notice from the battery replacement station 200. If the notice is received (Yes in step S80), the electric vehicle 100 completes the process. If the notice has not been received (No in step S80), the process of the electric vehicle 100 proceeds to step S90.

[0057] In step S90, the electric vehicle 100 checks whether it has received a notice indicating that a system abnormality has occurred from the battery replacement station 200. If the notice is received (Yes in step S90), the process of the electric vehicle 100 proceeds to step S100. If the notice has not been received (No in step S90), the electric vehicle 100 processes step S80 again.

[0058] In step S100, the electric vehicle 100 displays a second inquiry display on the HMI device 18. An example of the second inquiry display is shown in FIG. 5. The second inquiry display is displayed on the HMI device 18 of the electric vehicle 100, asking the user of the electric vehicle 100 to determine whether to perform emergency EV driving. The user selects and indicates the corresponding action that the electric vehicle 100 should take from the options displayed on the HMI device 18.

[0059] Referring to FIG. 4, in step S110, the electric vehicle 100 checks whether the user has input that emergency driving is to be performed in response to the second inquiry display. If the input indicating the need for implementation is confirmed (Yes in step S110), the electric vehicle 100 notifies the battery replacement station 200 that emergency start is required (step S120), and the process of the electric vehicle 100 proceeds to step S170. If the input indicating the need for implementation cannot be confirmed (No in step S110), the process of the electric vehicle 100 proceeds to step S112.

[0060] In step S112, the electric vehicle 100 checks whether the user has input that emergency driving is unnecessary in response to the second inquiry display. If it is confirmed that an unnecessary input has been made (Yes in step S112), the electric vehicle 100 notifies the battery exchange station 200 that emergency start is unnecessary (step S114), and ends the process.

[0061] In step S130, the battery exchange station 200 checks whether it has received a notification from the electric vehicle 100 that emergency start is required. If it has received the notification (Yes in step S130), the process of the battery exchange station 200 proceeds to step S140. If it has not received the notification (No in step S130), the process of the battery exchange station 200 proceeds to step S132.

[0062] In step S132, the battery exchange station 200 checks whether it has received a notification from the electric vehicle 100 that emergency start is unnecessary. If it has received the notification (Yes in step S132), the battery exchange station 200 ends the process. If it has not received the notification (No in step S130), the battery exchange station 200 processes step S130 again.

[0063] In step S140, the battery exchange station 200 shifts to a form in which the vehicle can start. During the battery exchange operation, the electric vehicle 100 cannot start because it is restrained by the drive device 230.

[0064] In step S150, the battery exchange station 200 checks whether the shift to a form in which the vehicle can start has been completed. If it can be confirmed that the shift has been completed (Yes in step S150), the process of the battery exchange station 200 proceeds to step S160. If it cannot be confirmed that the shift has been completed (No in step S160), the battery exchange station 200 processes step S150 again.

[0065] In step S160, the battery replacement station 200 notifies the electric vehicle 100 that the vehicle can start, and the battery replacement station 200 completes the process.

[0066] In step S170, the electric vehicle 100 checks whether it has received a notification that the vehicle can start. If it has received the notification (Yes in step S170), the process of the electric vehicle 100 proceeds to step S180. If it has not received the notification (No in step S170), the electric vehicle 100 processes step S170 again.

[0067] In step S180, the electric vehicle 100 starts supplying power from the auxiliary battery to the vehicle drive unit 11. Specifically, the EV-ECU 16 that has confirmed the completion of the transition to the vehicle start mode of the battery replacement station 200 via the communication device 17 checks that the SMR 12 is OFF and checks that the relay 15 is on. The power from the auxiliary battery 13 is boosted by the DC / DC converter 14, converted into three-phase alternating current by the inverter 11b, and supplied to the MG 11a.

[0068] As described above, in this embodiment, when a system abnormality occurs during the battery replacement operation by the battery replacement station 200, the battery replacement station 200 asks the electric vehicle 100 whether an emergency start is necessary. When the battery replacement station 200 receives a notification that an input indicating the necessity of an emergency start has been given, the battery replacement station 200 releases the restraint of the electric vehicle 100 so that the vehicle can start. Thereafter, the battery replacement station 200 notifies the electric vehicle 100 that it can transmit, and the electric vehicle 100 that has received the notification starts supplying power from the auxiliary battery to the vehicle drive unit 11.

[0069] In the above embodiment, an example in which power is supplied from the auxiliary battery 13 when a system abnormality occurs during the battery replacement operation has been shown, but the present disclosure is not limited thereto. For example, when the electric vehicle 100 determines that the battery 201 is abnormal after the replacement operation of the battery 201 by the battery replacement station 200 is completed, the electric vehicle 100 may start supplying power from the auxiliary battery 13 to the vehicle drive unit 11.

[0070] Referring to FIG. 6, the processing from the determination of the abnormality of the battery 201 to the power supply by the auxiliary battery will be described.

[0071] In step S500, the electric vehicle 100 checks whether the replacement of the battery 201 is completed. If it is confirmed that the replacement is completed (Yes in step S500), the processing of the electric vehicle 100 proceeds to step S510. If it cannot be confirmed that the replacement is completed (No in step S500), the electric vehicle 100 processes step S500 again.

[0072] In step S510, the electric vehicle 100 checks whether it is possible to drive by the battery 201. The case where the drivability cannot be confirmed is assumed to be insufficient SOC of the battery 201, poor connection of the terminals 19A and 19B, malfunction of the SMR12 and SMR22, and poor communication between the EV-ECU 16 and the Bat-ECU 23. If it is possible to drive (Yes in step S510), the electric vehicle 100 completes the processing. If it is not possible to drive (No in step S510), the processing of the electric vehicle 100 proceeds to step S520.

[0073] In step S520, the electric vehicle 100 causes the HMI device 18 to display a first inquiry display. An example of the first inquiry display is shown in FIG. 7. The first inquiry display is displayed on the HMI device 18 of the electric vehicle 100, and asks the user of the electric vehicle 100 to determine whether to perform emergency EV driving. The user selects and instructs the corresponding action that the electric vehicle 100 should take from the options displayed on the HMI device 18.

[0074] In step S530, the electric vehicle 100 checks whether the user has input a need for emergency driving in response to the first inquiry display. If it is confirmed that there is an input for emergency driving (Yes in step S530), the process of the electric vehicle 100 proceeds to step S550. If the input for emergency driving cannot be confirmed (No in step S530), the process of the electric vehicle 100 proceeds to step S540.

[0075] In step S540, the electric vehicle 100 checks whether the user has input a non - need for emergency driving in response to the first inquiry display. If it is confirmed that there is an input for non - emergency driving (Yes in step S540), the electric vehicle 100 completes the process. If the input for non - emergency driving cannot be confirmed (No in step S540), the electric vehicle 100 processes step S530 again.

[0076] In step S550, the electric vehicle 100 starts supplying power from the auxiliary battery to the vehicle drive unit 11 and completes the process.

[0077] In the above - mentioned embodiment, an example is shown in which, upon confirmation of whether the electric vehicle 100 has received a system abnormality notification from the battery exchange station 200 or whether driving by the battery 201 is possible, the user is asked to determine whether to perform an emergency EV drive. However, the present disclosure is not limited to this. For example, the electric vehicle 100 may ask the user to determine whether to perform an emergency EV drive when the user of the electric vehicle 100 turns on a hardware key provided on the vehicle.

[0078] In the above - mentioned embodiment, the inquiry display is shown on the HMI device 18 of the electric vehicle 100. However, the present disclosure is not limited to this. For example, the electric vehicle 100 may display the inquiry display on the mobile terminal 300.

[0079] In the above embodiments, the vehicle body 10 and the first battery 101 each have their own SMR, but the present disclosure is not limited thereto. For example, as shown in FIG. 8, the electric vehicle 100A includes a vehicle body 10A and a battery 101A. The vehicle body 10A does not have an SMR, and only the battery 101A may have an SMR22A. Similarly, as shown in FIG. 9, the electric vehicle 100B includes a vehicle body 10B and a battery 101B. Only the vehicle body 10B has an SMR12B, and the battery 101B may not have an SMR. Note that regarding other configurations and controls, since they are the same as those in the above embodiments of the present disclosure, repeated descriptions will not be given.
