[0001] The present disclosure relates to vehicles. [Background technology]
[0002] Japanese Patent Laid-Open Publication No. 2006-333551 (Patent Document 1) discloses a vehicle capable of generating a commercial AC voltage and supplying it to a load outside the vehicle. In Patent Document 1, the vehicle detects the current position of the vehicle using vehicle position information held by an on-board navigation device, and determines the frequency of the commercial AC voltage based on the detected current position of the vehicle. The vehicle generates a commercial AC voltage having the determined frequency and supplies it to the load. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2006-333551 A Summary of the Invention [Problem to be solved by the invention]
[0004] According to the vehicle described in Patent Document 1, by utilizing the position information possessed by the navigation device, it is possible to generate a commercial AC voltage having an appropriate frequency according to the region. However, on the other hand, in an environment where the frequency or voltage level of the commercial AC voltage differs from region to region, it is necessary to collect and store in advance information on the frequency and voltage level of the commercial AC voltage in each region in order to deal with the difference in frequency or voltage level. In this case, there is a concern that it will be difficult to collect and store all the information because there are a wide variety of types of AC voltage frequencies and voltage levels.
[0005] Here, as a configuration that does not use the position information of the navigation device, a configuration is considered in which the AC voltage supplied to the vehicle is detected and data on the frequency and voltage level of the AC voltage is obtained from the detected value. However, AC voltages are usually classified into single-phase AC voltage and three-phase AC voltage, and the voltage level or frequency may differ between the two. Therefore, in a vehicle that generates a single-phase AC voltage, there is a concern that data that is not suitable for generating a single-phase AC voltage may be obtained.
[0006] The present disclosure has been made to solve such problems, and has as its purpose to appropriately acquire data used to generate a single-phase AC voltage in a vehicle that is capable of receiving a single-phase or three-phase AC voltage from outside the vehicle and generating and supplying a single-phase AC voltage to the outside of the vehicle. [Means for solving the problem]
[0007] A vehicle according to an aspect of the present disclosure includes a power storage device, a power supply device, and a control device. The power supply device generates a single-phase AC voltage using power stored in the power storage device and supplies the single-phase AC voltage to an outside of the vehicle. The control device controls the power supply device. The control device includes a learning unit and a control unit. When the power supply device is connected to a power facility provided outside the vehicle, the learning unit acquires data related to at least one of a power level and a frequency of the AC voltage supplied from the power facility. The control unit generates a single-phase AC voltage to be supplied to the power facility by controlling the power supply device using the data acquired by the learning unit. The learning unit acquires data when the AC voltage supplied from the power facility is a single-phase AC voltage, but does not acquire data when the AC voltage supplied from the power facility is a three-phase AC voltage. Effect of the Invention
[0008] According to the present disclosure, in a vehicle capable of receiving a single-phase or three-phase AC voltage from outside the vehicle and generating and supplying a single-phase AC voltage to the outside of the vehicle, data used to generate the single-phase AC voltage can be appropriately acquired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] 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 designated by the same reference characters and their description will not be repeated.
[0011] <Overall composition> 1 is a diagram illustrating a schematic overall configuration of a power system including a vehicle according to an embodiment. The power system includes a vehicle 10, power equipment 20, a load device 400, a commercial power supply 500, and a switchboard 510. The power equipment 20 includes a power stand 200 and a Home Energy Management System (HEMS) 300. The HEMS 300, the load device 400, and the switchboard 510 are provided in a house 600.
[0012] The vehicle 10 is an electric vehicle that generates driving force for traveling using electric power and can receive and transmit electric power to and from the power station 200. The configuration of the electric vehicle is not particularly limited as long as it can run on electric power. The vehicle 10 includes, for example, a hybrid vehicle and an electric vehicle.
[0013] Vehicle 10 includes a power storage device 100, a connector 112, a power feeding device 110, a power output device 135, an ECU (Electronic Control Unit) 130, a communication device 140, and an HMI (Human Machine Interface) device 145.
[0014] The vehicle 10 is capable of charging the power storage device 100 by using power supplied from the power station 200. The vehicle 10 is also capable of discharging (feeding) the power of the power storage device 100 to the power station 200.
[0015] The power storage device 100 is a power storage element configured to be rechargeable, and is typically a secondary battery such as a lithium ion battery or a nickel-metal hydride battery. Alternatively, the power storage device 100 may be configured using a power storage element other than a battery, such as an electric double layer capacitor.
[0016] The connector 112 is configured to be connectable to a connector 212 provided at the tip of a power cable 214 of the power stand 200. The power supply device 110 is connected between the power storage device 100 and the connector 112. The power supply device 110 is controlled by a control signal from the ECU 130. The power supply device 110 has a charging unit 115 and a power supply unit 120. When charging the power storage device 100 with power supplied from the power stand 200, the charging unit 115 converts the power supplied from the power stand 200 into power that can be charged by the power storage device 100. When discharging from the power storage device 100 to the power stand 200, the power supply unit 120 converts the power of the power storage device 100 into power that can be received by the power stand 200. Configuration examples of each of the charging unit 115 and the power supply unit 120 will be described later.
[0017] The power output device 135 generates driving force for the vehicle 10 by using the electric power stored in the power storage device 100. Specifically, the power output device 135 generates driving force for the vehicle 10 based on a drive command signal from the ECU 130, and outputs the generated driving force to drive wheels (not shown) of the vehicle 10. In addition, the power output device 135 generates electric power when it receives a power generation command signal from the ECU 130, and supplies the generated electric power to the power storage device 100.
[0018] The communication device 140 is an interface for communicating with devices outside the vehicle (such as the power station 200 and the HEMS 300). The communication device 140 is connected to the EUC 130 via a communication line, and transmits information transmitted from the ECU 130 to the devices outside the vehicle and transmits information received from the devices outside the vehicle to the ECU 130.
[0019] The HMI device 145 is a device that provides various information to the user of the vehicle 10 and receives operations from the user of the vehicle 10. The HMI device 145 includes a display equipped with a touch panel, a speaker, and the like.
[0020] Furthermore, although not shown, vehicle 10 includes a plurality of sensors for detecting various physical quantities necessary for controlling vehicle 10, such as a vehicle speed sensor for detecting the vehicle speed and a monitoring sensor for detecting the state (voltage, current, temperature, etc.) of power storage device 100. Each of these sensors outputs the detection results to ECU 130.
[0021] The ECU 130 incorporates a processor 131 and a memory 132, and controls each device of the vehicle 10 based on information stored in the memory 132 and information from each sensor. Note that these controls are not limited to processing by software, and can also be processed by configuring dedicated hardware (electronic circuits). The ECU 130 corresponds to one embodiment of a "control device."
[0022] The ECU 130 communicates, via the communication device 140, wirelessly or via wire with communication devices 240, 350 provided in the power station 200 and the HEMS 300, respectively, which are provided outside the vehicle.
[0023] The power station 200 is a facility for charging and discharging the vehicle 10. The power station 200 includes a power cable 214, a relay 210, a controller 230, and a communication device 240. The power station 200 is electrically connected to a switchboard 510 via the HEMS 300. The power station 200 may be provided inside a house 600.
[0024] A first end of power cable 214 is connected to relay 210, and a second end of power cable 214 is provided with connector 212. When power is supplied to vehicle 10 or when power is received from vehicle 10, connector 212 of power cable 214 is connected to connector 112 of vehicle 10, and relay 210 is closed. The opening and closing operation of relay 210 is controlled by controller 230.
[0025] The HEMS 300 is electrically connected to the switchboard 510 and the power stand 200. The HEMS 300 includes a power conditioning system (PCS) 310, a DC / AC converter 320, a storage battery 330, a CPU 340, and a communication device 350. The PCS 310 and the DC / AC converter 320 are controlled by the CPU 340.
[0026] The DC / AC converter 320 is connected to the vehicle 10 via the power stand 200. The DC / AC converter 320 converts AC power supplied from the vehicle 10 via the power stand 200 into DC power, and outputs the DC power to the PCS 310 and the storage battery 330. The DC / AC converter 320 also converts DC power supplied from at least one of the PCS 310 and the storage battery 330 into AC power, and outputs the AC power to the vehicle 10 via the power stand 200.
[0027] The PCS 310 is connected to the system power supply 500 via a distribution board 510. The system power supply 500 is configured with a single-phase AC or three-phase AC power supply. The PCS 310 converts AC power supplied from the system power supply 500 via the distribution board 510 into DC power, and outputs the DC power to the DC / AC converter 320 and the storage battery 330. Meanwhile, the PCS 320 can convert DC power supplied from at least one of the storage battery 330 and the DC / AC converter 320 (the power storage device 100 of the vehicle 10) into AC power, and output the AC power to the system power supply 500 via the distribution board 510.
[0028] The storage battery 330 is a rechargeable power storage device, and typically includes a secondary battery such as a lithium ion battery, a nickel metal hydride battery, or a lead storage battery. In addition to the power from the vehicle 10, the storage battery 330 may be supplied with power generated by a solar panel (not shown) installed in the house 600. Furthermore, the storage battery 330 may be supplied with power from the system power supply 500.
[0029] The load device 400 is any electric device that operates by receiving power from the switchboard 510. The load device 400 is, for example, a household electrical appliance used in a house 600.
[0030] <Configuration of power supply device> 2 is a diagram showing an example of a configuration of a power supplying device 110 mounted on the vehicle 10. The power supplying device 110 includes a charging unit 115 and a power supplying unit 120.
[0031] Charging unit 115 converts AC power supplied from power equipment 20 via connector 112 into DC power, and outputs the DC power to power storage device 100. Charging unit 115 includes a high power factor converter circuit 117 and a smoothing capacitor C.
[0032] The high power factor converter circuit 117 includes reactors L1 to L3, semiconductor switching elements (hereinafter also simply referred to as "switching elements") Q1 to Q6, and diodes D1 to D6. The switching elements Q1 to Q6 are, for example, IGBTs (Insulated Gate Bipolar Transistors).
[0033] The collectors of the switching elements Q1, Q3, and Q5 are all connected to the DC positive bus PL1, and the emitters thereof are connected to first terminals of the reactors L1 to L3, respectively. Second terminals of the reactors L1 to L3 are connected to the connector 112.
[0034] The collectors of switching elements Q2, Q4, Q6 are connected to first terminals of reactors L1 to L3, respectively, and the emitters thereof are both connected to the DC negative bus NL1. Diodes D1 to D6 are connected in anti-parallel to switching elements Q1 to Q6, respectively.
[0035] The switching elements Q1 and Q2 constitute a "first leg circuit," the switching elements Q3 and Q4 constitute a "second leg circuit," and the switching elements Q5 and Q6 constitute a "third leg circuit." Each of the switching elements Q1 to Q6 is controlled by a gate signal from the ECU 130 (charging control unit 134). The gate signal is a pulse signal train, for example a PWM (Pulse Width Modulation) signal.
[0036] The smoothing capacitor C is connected between the DC positive bus PL1 and the DC negative bus NL1, and stabilizes the DC voltage between the DC positive bus PL1 and the DC negative bus NL1.
[0037] The high power factor converter circuit 117 is controlled by the ECU 130 (the charging control unit 134), and is configured to convert the three-phase AC voltage into a DC voltage when the three-phase AC voltage is supplied via the connector 112. Specifically, the high power factor converter circuit 117 turns on and off each of the switching elements Q1 to Q6 at a predetermined timing by a gate signal, and adjusts the on time of each of the switching elements Q1 to Q6, thereby being able to convert the three-phase AC voltage input to the connector 112 into a DC voltage.
[0038] Moreover, when a single-phase AC voltage is supplied via the connector 112, the high power factor converter circuit 117 is configured to convert the single-phase AC voltage into a DC voltage. Specifically, the high power factor converter circuit 117 turns on and off each of four switching elements included in any two of the first to third leg circuits at a predetermined timing by a gate signal, and adjusts the on time of each of the four switching elements. At this time, the two switching elements included in the remaining leg circuit are turned off. This makes it possible to convert the single-phase AC voltage input to the connector 112 into a DC voltage.
[0039] Power supply unit 120 converts DC power supplied from power storage device 100 into AC power, and outputs the AC power to power equipment 20 via connector 112. Power supply unit 120 includes a single-phase inverter circuit 122.
[0040] The single-phase inverter circuit 122 includes reactors L4 and L5, switching elements Q11 to Q14, and diodes D11 to D14. The switching elements Q11 to Q14 are, for example, IGBTs.
[0041] The collectors of the switching elements Q11 and Q13 are both connected to the DC positive bus PL1, and the emitters thereof are connected to first terminals of reactors L4 and L5, respectively. Second terminals of the reactors L4 and L5 are connected to the connector 112.
[0042] The collectors of switching elements Q12 and Q14 are connected to first terminals of reactors L4 and L5, respectively, and their emitters are both connected to the DC negative bus NL1. Diodes D11-D14 are connected in anti-parallel to switching elements Q11-Q14, respectively. Each of switching elements Q11-Q14 is controlled by a gate signal from ECU 130 (power supply control unit 139). The gate signal is a pulse signal train, for example, a PWM signal.
[0043] The single-phase inverter circuit 122 is controlled by the ECU 130 (power supply control unit 139) and is configured to convert the DC voltage of the power storage device 100 into a single-phase AC voltage. Specifically, the single-phase inverter circuit 122 turns on and off each of the switching elements Q11-Q14 at a predetermined timing by a gate signal and adjusts the on time of each of the switching elements Q11-Q14, thereby being able to convert the DC voltage of the power storage device 100 into a single-phase AC voltage.
[0044] ECU 130 has a voltage detector 133, a charging control unit 134, a learning unit 136, a storage unit 137, and a power supply control unit 139 as components for controlling charging and discharging of power storage device 100. Each of the above units is embodied by processor 131 shown in Fig. 1 executing a program stored in memory 132. However, without being limited thereto, each of the above units may be embodied by dedicated hardware (electronic circuits).
[0045] Voltage detector 133 detects the AC voltage applied to connector 112 from power equipment 20, and provides a signal indicating the detected value to charging control unit 134 and learning unit 136.
[0046] When charging the power storage device 100 with power supplied from the power station 200, the charging control unit 134 controls the charging unit 115 (high power factor converter circuit 117) based on a signal from the voltage detector 133, etc. Specifically, when a three-phase AC voltage is applied to the connector 112, the charging control unit 134 turns on and off each of the switching elements Q1 to Q6 of the high power factor converter circuit 117. As a result, the three-phase AC voltage supplied via the connector 112 is converted into a DC voltage by the charging unit 115, and the power storage device 100 is charged with the DC voltage.
[0047] Furthermore, when a single-phase AC voltage is applied to the connector 112, the charging control unit 134 turns on and off each of the four switching elements (for example, the first and third leg circuits) while maintaining two switching elements (for example, the second leg circuit) in the off state among the switching elements Q1 to Q6 of the high power factor converter circuit 117. As a result, the single-phase AC voltage supplied via the connector 112 is converted to a DC voltage by the charging unit 115, and the power storage device 100 is charged with the DC voltage.
[0048] Based on the signal from the voltage detector 133, the learning unit 136 acquires data regarding the voltage level and frequency of the AC voltage applied to the connector 112. Specifically, based on the detection value of the voltage detector 133, the learning unit 136 calculates the effective value of the AC voltage applied to the connector 112. Based on the detection value of the voltage detector 133, the learning unit 136 also calculates the frequency of the AC voltage applied to the connector 112.
[0049] In this embodiment, learning section 136 is configured to calculate the voltage level and frequency of the AC voltage, but may be configured to calculate at least one of the voltage level and frequency of the AC voltage.
[0050] Fig. 3 is a diagram showing an example of the configuration of the learning section 136. As shown in Fig. 3, the learning section 136 includes a sampling circuit 142, an A / D converter 144, and an arithmetic circuit 146.
[0051] Sampling circuit 142 samples the detection value obtained by voltage detector 133. A / D converter 144 converts the sampled data into digital data and outputs it to arithmetic circuit 146. Arithmetic circuit 146 calculates the effective value of the AC voltage by aggregating and calculating the digital data obtained by sampling during one period of the detection value. Various known methods can be applied to calculate the effective value. For example, a method is used in which the squared values of the digital data are summed up and the square root of the sum is taken as the effective value.
[0052] The arithmetic circuit 146 also calculates the frequency of the AC voltage based on the digital data. Various known methods can be used to calculate the frequency. For example, a method is used in which a zero-cross point at the rising edge of the detection value is detected, and the frequency of the AC voltage is calculated based on the detected zero-cross point.
[0053] Returning to FIG. 2, the learning unit 136 stores the acquired data in the storage unit 137. When discharging from the power storage device 100 to the power stand 200, the power supply control unit 139 controls the power supply unit 120 (single-phase inverter circuit 122) by using the data stored in the memory unit 137. Specifically, the power supply control unit 139 turns on and off each of the switching elements Q11 to Q14 of the single-phase inverter circuit 122 so that a single-phase AC voltage having a voltage level and frequency indicated by the data is output from the connector 112. As a result, the DC voltage supplied from the power storage device 100 is converted into a single-phase AC voltage by the power supply unit 120, and the single-phase AC voltage is supplied to the power stand 200 via the connector 112.
[0054] The learning unit 136 is configured to acquire data on the voltage level and frequency of the AC voltage, using the detection value of the voltage detector 133 during the period from when the AC voltage is applied from the power stand 200 to the connector 112 until the charging unit 115 is started and charging of the power storage device 100 is started. This is because, when the voltage conversion operation in the charging unit 115 (high power factor converter circuit 117) is started, a voltage drop occurs in the AC voltage applied to the connector 112 due to the impedance component of the charging unit 115, and therefore an accurate voltage level (i.e., effective value) cannot be detected.
[0055] Furthermore, the learning unit 136 is configured to acquire the above-mentioned data on the voltage level and frequency when the AC voltage applied from the power stand 200 to the connector 112 is a single-phase AC voltage, but not to acquire the data when the AC voltage applied to the connector 112 is a three-phase AC voltage. This is because the voltage level (effective value) or frequency may differ between a three-phase AC voltage and a single-phase AC voltage.
[0056] For example, a single-phase 100V or single-phase 200V AC voltage is usually supplied to a consumer from the distribution board 510, but a three-phase 200V AC voltage may be supplied depending on the consumer's needs. By calculating the voltage level based on the detection value of the voltage detector 133 when a three-phase 200V AC voltage is applied to the connector 112, a voltage level may not match between the single-phase AC voltage supplied to the house 600 from the power supply unit 120 via the power stand 200 and the single-phase AC voltage supplied from the distribution board 510. In addition, a similar event may occur when the single-phase AC voltage and the three-phase AC voltage applied to the connector 112 have different frequencies. Therefore, when a three-phase AC voltage is applied to the connector 112, the occurrence of such a malfunction can be prevented by configuring the device not to acquire data on the voltage level and frequency of the AC voltage.
[0057] FIG. 4 is a flowchart showing an example of a procedure of a charge / discharge control process executed by the ECU 130 of the vehicle 10. As shown in FIG.
[0058] 4, in step S01, ECU 130 determines whether or not connector 112 of vehicle 10 is connected to connector 212 of power cable 214. If connector 112 is not connected to connector 212, ECU 130 ends the process.
[0059] On the other hand, when the connector 112 and the connector 212 are connected (YES in S01), the ECU 130 determines in step S02 whether learning about the voltage level and frequency of the AC voltage has been completed. In S02, if data about the voltage level and frequency of the AC voltage is stored in the memory 132, a YES determination is made, and if the data is not stored in the memory 132, a NO determination is made.
[0060] When it is determined that the learning is completed (NO in S02), the ECU 130 proceeds to S08. When charging the vehicle 10, the ECU 130 controls the charging unit 115 to convert the AC voltage (single-phase AC voltage or three-phase AC voltage) supplied from the power stand 200 via the connector 112 into a DC voltage. When discharging the vehicle 10 (power supply from the vehicle 10), the ECU 130 controls the power supply unit 120 to convert the DC voltage of the power storage device 100 into a single-phase AC voltage. The ECU 130 controls the power supply unit 120 using data related to the voltage level and frequency of the AC voltage stored in the memory 132. As a result, a single-phase AC voltage having a voltage level and frequency indicated by the data is generated and output from the connector 112 to the power stand 200.
[0061] On the other hand, if it is determined in S02 that the learning is not completed (NO in S02), ECU 130 executes the processes of steps S03 to S07 to execute a learning process for acquiring data related to the voltage level and frequency of the AC voltage.
[0062] Specifically, in step S03, ECU 130 notifies the user that charging of power storage device 100 will be performed in order to apply an AC voltage to connector 112. This notification can be performed using HMI device 145, for example.
[0063] Next, in step S04, the ECU 130 executes a process for turning on the relay 210 of the power stand 200. For example, the ECU 130 can turn on the relay 210 by transmitting an on command for the relay 210 from the communication device 140 to the communication device 240 of the power stand 200.
[0064] When relay 210 is turned on and AC voltage from power station 200 is applied to connector 112, ECU 130 determines in step S05 based on the detection value of voltage detector 133 whether the AC voltage applied to connector 112 is a single-phase AC voltage.
[0065] If a single-phase AC voltage is applied to connector 112 (YES in S05), ECU 130 proceeds to S06 and acquires data related to the voltage level and frequency of the single-phase AC voltage. In step S07, ECU 130 stores the acquired data (learned data) in memory 132. This completes learning of the voltage level and frequency of the AC voltage.
[0066] When the learning is completed, ECU 130 proceeds to step S08 and starts charging or discharging (power supply) vehicle 10. When charging vehicle 10, ECU 130 activates high power factor converter circuit 117 of charging unit 115 to convert the AC voltage (single-phase AC voltage or three-phase AC voltage) supplied from power stand 200 via connector 112 into a DC voltage.
[0067] Furthermore, when discharging the vehicle 10 (power supply from the vehicle 10), the ECU 130 stops the supply of AC voltage from the power stand 200 by communicating with the power stand 200. Then, the ECU 130 controls the power supply unit 120 using data related to the voltage level and frequency of the AC voltage stored in the memory 132, thereby generating a single-phase AC voltage having a voltage level and frequency indicated by the data, and outputs the single-phase AC voltage from the connector 112 to the power stand 200.
[0068] In step S09, ECU 130 determines whether charging or power supply should be terminated. In S09, for example, a YES determination is made when charging or power supply is completed or when connector 112 is detached from connector 212. When it is determined that charging or power supply should be terminated (YES determination in S09), ECU 130 terminates a series of charge / discharge controls.
[0069] As described above, according to this embodiment, in a configuration for acquiring data on the voltage level and frequency used when generating a single-phase AC voltage to be supplied from a vehicle based on the AC voltage applied to the connector 112 of the vehicle, if the AC voltage applied to the connector 112 is a three-phase AC voltage, the data is not acquired. This makes it possible to prevent erroneous data from being acquired when the voltage level or frequency differs between the three-phase AC voltage and the single-phase AC voltage. As a result, it becomes possible to appropriately acquire data used for generating the single-phase AC voltage.
[0070] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects.
