Description

[Technical field]

[0001] The present invention relates to an electricity consumption measurement system, an electricity data management device, a driving test management device, an electricity consumption measurement method, and a program recording medium for the electricity consumption measurement system. [Background technology]

[0002] In recent years, with the need for electrification in the automobile market, there has been an increase in testing of vehicles that use electricity as an energy source, such as EVs (electric vehicles) and PHVs (plug-in hybrid vehicles). In testing of such vehicles, it is required to measure the power consumption rate (hereinafter, also simply referred to as "electricity consumption") as one of the evaluation items. In measuring this electricity consumption, as described in Patent Document 1, for example, a running test of the vehicle is performed on a road or on a chassis dynamometer, and the amount of electricity consumed during the running test is measured, and the electricity consumption is calculated using this amount of power consumption and the distance traveled during the running test.

[0003] Conventionally, in measuring such electricity consumption, the amount of power consumption of a vehicle measured during a driving test, for example, is typically manually entered by an operator into a computer that manages the driving test, and the electricity consumption is then calculated based on this manually entered amount of power consumption. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-102221 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned method of measuring electricity consumption, the operator manually inputs the amount of power consumption measured by a power meter or the like into a computer for calculating electricity consumption, so there is a risk of inputting errors into the power data indicating the amount of power consumption. Also, for example, when running tests or charging are performed on multiple vehicles and there are multiple pieces of power data and mileage data indicating mileage, there is a risk of mixing up the power data input into the computer.

[0006] Therefore, the main objective of the present invention is to reduce the occurrence of input errors or mix-ups of power data due to human error in an electricity consumption measurement system that measures the electricity consumption of a vehicle during a driving test, and to improve the accuracy of electricity consumption calculation. [Means for solving the problem]

[0007] In other words, the electricity consumption measurement system of the present invention measures the electricity consumption during a driving test of a vehicle or part thereof that uses electricity as an energy source, and is characterized by comprising a driving data management unit that acquires mileage data indicating the mileage of the vehicle or part thereof during the driving test and stores the mileage data together with a predetermined vehicle identifier assigned to the vehicle or part thereof, a power data management unit that acquires power data indicating the amount of power required to charge a battery provided in the vehicle or part thereof to a predetermined amount before or after the driving test and stores the power data together with the vehicle identifier, and an electricity consumption calculation unit that links the mileage data and the power data that match the vehicle identifier, and calculates the electricity consumption of the vehicle or part thereof during the driving test using the linked mileage data and power data. Note that the vehicle or part thereof that uses electricity as an energy source is not necessarily limited to a complete vehicle, but may be a drive system having a motor.

[0008] In this way, the electricity cost calculation unit is configured to automatically link the mileage data and the power data, which reduces data input errors caused by the operator manually inputting the power data. In addition, since both the power data and the mileage data are stored together with the vehicle identifier, and the electricity cost calculation unit links the mileage data and the power data that have the same vehicle identifier, even if a driving test or charging is performed on multiple vehicles and multiple power data and mileage data exist, it is possible to prevent the power data and mileage data of different vehicles from being erroneously linked. This improves the accuracy of the electricity cost calculation.

[0009] In one embodiment of the electricity consumption measurement system, the amount of electricity is measured by a power meter connected to a charging facility that supplies power to the battery.

[0010] It is preferable that in the electricity consumption measurement system, the power data indicates the amount of power required to fully charge the battery.

[0011] In one embodiment of the electricity consumption measurement system, the battery is charged in a soak room before or after the running test.

[0012] It is preferable that the electricity consumption measurement system is configured such that a symbol representing the vehicle identifier is attached to the vehicle or part thereof, and further includes a reading unit that reads the vehicle identifier from the symbol, the driving data management unit obtains the vehicle identifier read by the reading unit and stores the vehicle identifier in association with the mileage data, and the power data management unit obtains the vehicle identifier read by the reading unit and stores the vehicle identifier in association with the power data. In this way, the vehicle identifier can be obtained by reading the symbol attached to the vehicle with the reading unit when performing a driving test or charging, and this can be linked to the driving data and charging data and stored, thereby reducing the occurrence of human errors such as input errors that can occur when the operator enters the vehicle identifier himself.

[0013] It is preferable that the function of the reading unit in the electricity consumption measurement system is realized by a portable terminal device. In this way, the vehicle identifier can be read by bringing the terminal device close to the vehicle while it is set in the driving test equipment or charging facility, thereby preventing human error such as mistakenly reading the vehicle identifier of a vehicle that is not related to the driving test.

[0014] The electricity consumption measurement system preferably further comprises a running test device for carrying out the running test. Specific examples of the running test device include a chassis dynamometer or a vehicle drivetrain test device.

[0015] In addition, the power data management device of the present invention manages the charging amount before or after a driving test of a vehicle or part thereof that uses electricity as an energy source, and is characterized by having a power data acquisition unit that acquires power data indicating the amount of power required to charge the battery of the vehicle or part thereof to a predetermined amount before or after the driving test, a vehicle identifier acquisition unit that acquires a predetermined vehicle identifier assigned to the vehicle or part thereof, and a power data storage unit that stores the power data in association with the vehicle identifier.

[0016] In addition, the driving test management device of the present invention manages driving tests of a vehicle or part thereof that uses electricity as an energy source, and is characterized in that it comprises a driving data acquisition unit that acquires mileage data indicating the mileage of the vehicle or part thereof during the driving test, a vehicle identifier acquisition unit that acquires a predetermined vehicle identifier assigned to the vehicle or part thereof, a driving data storage unit that links the mileage data to the vehicle identifier and stores it, and an electricity consumption calculation unit that links the mileage data whose vehicle identifiers match with power data indicating the amount of electricity required to charge the battery of the vehicle or part thereof to a predetermined amount before or after the driving test, and calculates the electricity consumption of the vehicle or part thereof during the driving test using the linked mileage data and power data.

[0017] According to the power data management device and the driving test management device of the present invention, it is possible to achieve the same effects as those of the above-mentioned power consumption measurement system of the present invention.

[0018] In addition, the electricity consumption measurement method of the present invention is a method for measuring the electricity consumption during a driving test of a vehicle or part thereof that uses electricity as an energy source, and is characterized in that it includes a driving data management step of acquiring mileage data indicating the mileage of the vehicle or part thereof during the driving test and storing the mileage data together with a predetermined vehicle identifier assigned to the vehicle or part thereof, a power data management step of acquiring power data indicating the amount of power required to charge the battery of the vehicle or part thereof to a predetermined amount before or after the driving test and storing the power data together with the vehicle identifier, and an electricity consumption calculation step of linking the mileage data and the power data that match the vehicle identifier, and calculating the electricity consumption of the vehicle or part thereof during the driving test using the linked mileage data and power data. According to the electricity consumption measurement method of the present invention, it is possible to achieve the same effects as those of the electricity consumption measurement system of the present invention described above.

[0019] In addition, the program recording medium for the electricity consumption measurement system of the present invention is for recording a program for measuring the electricity consumption during a driving test of a vehicle or part thereof that uses electricity as an energy source, and is characterized in that it records a program that causes a computer to perform the following functions as a driving data management unit: acquiring mileage data indicating the mileage of the vehicle or part thereof during the driving test, and storing the mileage data together with a predetermined vehicle identifier assigned to the vehicle or part thereof; acquiring power data indicating the amount of power required to charge the battery of the vehicle or part thereof to a predetermined amount before or after the driving test, and storing the power data together with the vehicle identifier; and linking the mileage data and the power data that match the vehicle identifier, and calculating the electricity consumption of the vehicle or part thereof during the driving test using the linked mileage data and power data.

[0023] Hereinafter, an electricity consumption measurement system according to one embodiment of the present invention will be described with reference to the drawings.

[0024] The electricity consumption measurement system 100 of this embodiment is for measuring the power consumption rate (hereinafter also referred to as electricity consumption) during a running test of a completed vehicle V (hereinafter simply referred to as a vehicle), such as an EV or PHV, that is driven using electricity as an energy source. Specifically, this electricity consumption measurement system 100 calculates the electricity consumption of the vehicle V based on the travel distance of the vehicle V during the running test and the amount of electricity consumed by the driving battery (hereinafter simply referred to as a battery) of the vehicle V during the running test. In this electricity consumption measurement system 100, after a running test is performed on a fully charged vehicle V, the amount of electricity required to charge the vehicle V and return it to a fully charged state is measured, and the measured amount of electricity is used as the amount of power consumed during the running test to calculate the electricity consumption. Below, the configuration of the electricity consumption measurement system 100 will be specifically described.

[0025] Specifically, as shown in FIG. 1, this electricity consumption measurement system 100 includes a driving test device 1 that performs a driving test on a vehicle V, a vehicle charging system 2 that charges the vehicle V before and after the driving test, and a driving test management device 3 that controls the driving test device 1 and calculates the electricity consumption of the vehicle V during the driving test.

[0026] The running test device 1 is specifically a chassis dynamometer, and is arranged in a test room. The chassis dynamometer 1 includes rollers 11 on which the wheels of a vehicle V are placed, and a motor (not shown) connected to the rollers 11. The motor is configured to control the rollers 11 with a predetermined torque.

[0027] The vehicle charging system 2 includes a charging facility 21 that supplies power to the battery of the vehicle V to charge it, a power meter 22 that measures the amount of power supplied by the charging facility 21 to the battery, and a power data management device 23 (also referred to as a power data management unit) that controls the operation of the power meter 22 and manages the amount of power measured by the power meter 22. The vehicle charging system 2 of this embodiment includes a plurality of (two in this case) charging facilities 21 and a plurality of (two in this case) power meters 22 corresponding to each charging facility 21.

[0028] This vehicle charging system 2 is installed in a vehicle storage room called a soak room, which is used to keep the vehicle V at a predetermined constant temperature (for example, around 25°C) depending on the type of driving test. This soak room is configured to be able to simultaneously store multiple vehicles V. Before and after the driving test, the vehicle V is placed in the soak room and charged.

[0029] The charging facility 21 uses an AC power source. The charging facility 21 of this embodiment is a so-called outlet type that includes a charging outlet 211 into which a power plug of a charging cable, one end of which is connected to a charging port of the vehicle V, is inserted, and an AC power source 212 that supplies power to the outlet 211. The charging facility 21 is not limited to this, and may be a so-called charging pole type.

[0030] The power meter 22 measures the power supplied from the charging equipment 21 to the battery of the vehicle V, and has a measurement accuracy that complies with various test methods. The power meter 22 is connected to a power supply line provided in the charging equipment 21, and more specifically, a probe provided in the power meter 22 is connected to an electric wire that connects between the charging outlet 211 and the AC power source 212 provided in the charging equipment 21.

[0031] The power data management device 23 is a dedicated or general-purpose computer equipped with a CPU, an internal memory, an input / output interface, an A / D converter, etc. Based on a predetermined program stored in the internal memory, the CPU and peripheral devices work together to perform at least the functions of a power data acquisition unit 231, a power data storage unit 232, a peripheral data acquisition unit 235, and a peripheral data storage unit 236, as shown in Fig. 2. The power data management device 23 is a portable terminal device such as a tablet, smartphone, or notebook computer, and can be carried between the soak room and the test room.

[0032] The power data acquisition unit 231 acquires power data indicating various information related to power measured by the power meter 22 during charging before and / or after the driving test. The information indicated by this power data includes at least the integrated amount of power required to charge the battery to a predetermined amount (herein, fully charged) before and / or after the driving test (hereinafter also referred to as post-test charge amount). Furthermore, the information indicated by the power data in this embodiment may further include an instantaneous power value, instantaneous current value, instantaneous voltage value, average values ​​of power amount, current, and voltage of the power supplied from the charging equipment 21 during charging, a charging start time, a charging end time, or a charging time. The power data acquisition unit 231 may also have a function of storing identification information (outlet identification information) specific to the outlet used for charging. In particular, when there are multiple power meters 22, the power data acquisition unit 231 may have a function of sending a measurement command to the power meter 22 that matches the outlet identification information acquired by the operator before measurement.

[0033] The power data storage unit 232 is set in a predetermined area of ​​the memory, and stores the power data acquired by the power data acquisition unit 231.

[0034] The surrounding data acquisition unit 235 acquires surrounding information of the vehicle V during a driving test or charging. This surrounding information is, for example, the tire pressure, coolant temperature, lubricant temperature, room temperature, etc. of the vehicle V. The surrounding data acquisition unit 235 may acquire surrounding data by user input, or may acquire surrounding data by receiving measurement results from any measuring device via wired or wireless connection. The surrounding data acquisition unit 235 stores the acquired surrounding data in the surrounding data storage unit 236 set in a predetermined area of ​​the memory.

[0035] The driving test management device 3 is a dedicated or general-purpose computer equipped with a CPU, internal memory, an input / output interface, an A / D converter, etc. Based on a program for the electricity consumption measurement system 100 stored in the internal memory, the driving test management device 3 at least performs the functions of a test device control unit 31, a driving data management unit 32, and an electricity consumption calculation unit 33, as shown in Fig. 2, by the CPU and peripheral devices working together.

[0036] The test device control unit 31 performs a running test on the vehicle V placed on the chassis dynamometer 1 in a predetermined running mode (for example, STP (Shortened Test Procedure) mode or a running mode arbitrarily determined by the user, etc.) defined by a standard. When the test device control unit 31 of this embodiment receives a predetermined operation from a user via an input / output interface, it starts running the vehicle V in the predetermined running mode, and then continues the running until a predetermined termination condition is reached. The predetermined termination condition is, for example, a situation in which deviation from the allowable error of mode tracking continues due to a lack of remaining battery charge, a situation in which the remaining battery charge of the vehicle V falls below a predetermined value, a vehicle stop instruction is issued by a battery remaining charge warning device of the vehicle V, and the like. In addition, the predetermined termination condition may be that the running mode is terminated according to a predetermined coefficient. The predetermined coefficient is, for example, calculated based on an energy requirement, an electric energy, and / or a total fuel input amount. Alternatively, the predetermined termination condition may be when the vehicle ends a predetermined running mode, when the work load of the vehicle reaches a predetermined value, and the like. The test device control unit 31 outputs mileage data indicating the mileage of the vehicle V in the running test. The mileage indicated by the mileage data is the total accumulated distance of the vehicle V from the start to the end of the mode cycle running (i.e., until the termination condition is reached), and is calculated, for example, from the number of rotations of the rollers 11 of the chassis dynamometer 1 and various counts. The mileage data also includes the start time, end time, etc. of the running test.

[0037] The driving data management unit 32 manages information related to driving tests, and has a driving data acquisition unit 321 that acquires driving distance data from the test equipment control unit 31, and a driving data memory unit 322 that stores the acquired driving distance data.

[0038] The electricity consumption calculation unit 33 acquires the mileage data stored in the traveling data storage unit 322 and the power data stored in the power data storage unit 232, and calculates the electricity consumption of the vehicle V in the traveling test using the mileage data and the power data. Specifically, the electricity consumption calculation unit 33 calculates the electricity consumption C [Wh / km] based on the following formula (1) using the traveling distance D [km] in the traveling test indicated by the mileage data and the post-test charge amount E [kWh] indicated by the power data. C = E × 1000 / D (1) As can be seen from equation (1), electricity efficiency means the AC power consumption rate per 1 km traveled.

[0039] Thus, in the electricity consumption measurement system 100 of this embodiment, the traveling data management unit 32 is configured to store the acquired traveling distance data together with the vehicle identifier assigned to the vehicle V, and the power data management unit 23 is configured to store the acquired power data together with the vehicle identifier assigned to the vehicle V. The electricity consumption calculation unit 33 is configured to link the traveling distance data and the power data that have a matching vehicle identifier, and to calculate the electricity consumption based on the linked traveling distance data and power data.

[0040] To achieve this configuration, in the electricity consumption measurement system 100 of this embodiment, as shown in Fig. 1, a symbol Sv representing a vehicle identifier is attached to each vehicle V undergoing a driving test. Here, the vehicle identifier is a vehicle identification number (VIN), and the symbol Sv is a two-dimensional code having information in the horizontal and vertical directions. As shown in Fig. 2, the electricity data management unit 23 is configured to further function as a reading unit 233 and a first vehicle identifier acquisition unit 234, and the driving data management unit 32 is configured to further function as a second vehicle identifier acquisition unit 323.

[0041] The reading unit 233 reads, by contact or non-contact, the vehicle identifier from the symbol Sv attached to the vehicle V. Specifically, the reading unit 233 is configured to read the vehicle identifier based on an image of the symbol Sv captured by a camera provided in the power data management device 23. The reading unit 233 outputs the read vehicle identifier as vehicle identifier data.

[0042] When the first vehicle identifier acquisition unit 234 receives the vehicle identifier data, it transmits it to the power data acquisition unit 231. Then, the power data acquisition unit 231 associates the power data acquired from the power meter 22 with the vehicle identifier data accepted from the first vehicle identifier acquisition unit 234, and stores them in the power data storage unit 232.

[0043] Furthermore, when the first vehicle identifier acquisition unit 234 receives the vehicle identifier data, it transmits it to the surrounding data acquisition unit 235. Then, the surrounding data acquisition unit 235 associates the surrounding data acquired by the user's input with the vehicle identifier data accepted from the first vehicle identifier acquisition unit 234, and stores them in the surrounding data storage unit 236.

[0044] Furthermore, when the second vehicle identifier acquisition unit 323 receives the vehicle identifier data, it transmits the same to the traveling data acquisition unit 321. Then, the traveling data acquisition unit 321 associates the traveling distance data acquired from the test equipment control unit 31 with the vehicle identifier data accepted from the second vehicle identifier acquisition unit 323, and stores them in the traveling data storage unit 322.

[0045] The electricity consumption calculation unit 33 is configured to receive the electricity consumption data stored in the electricity consumption data storage unit 232, and to compare the vehicle identifier of the electricity consumption data with the vehicle identifier of the mileage data stored in the mileage data storage unit 322. If these vehicle identifiers match, the electricity consumption calculation unit 33 is configured to link the mileage data with the electricity data, calculate the electricity consumption based on the mileage indicated by the linked mileage data and the amount of electricity indicated by the electricity data, and output this as electricity consumption data. The electricity consumption calculation unit 33 may output the calculated electricity consumption data by linking it to the vehicle identifier.

[0046] The electricity consumption calculation unit 33 is also configured to receive the surrounding data stored in the surrounding data storage unit 236, and to compare the vehicle identifier of the surrounding data with the vehicle identifier of the mileage data stored in the travel data storage unit 322. If these vehicle identifiers match, the calculated electricity consumption data and the surrounding data may be linked and output.

[0047] The electricity cost calculation unit 33 also functions as an alarm unit that notifies the user when the received power data does not match the mileage data stored in the travel data storage unit 322. Specifically, the alarm unit checks the vehicle identifier of the received power data against the vehicle identifier of the mileage data stored in the travel data storage unit 322, and notifies the user when they do not match, when at least one of the power data and the mileage data is not linked to a vehicle identifier, or when the time indicated by the power data does not match the time indicated by the mileage data. For example, the alarm unit displays a message such as "Data does not match" on a display provided in the travel test management device 3, or emits a warning sound from a speaker.

[0048] In the electricity consumption measurement system 100 of this embodiment, as shown in Fig. 1, the outlet 211 may be provided with a symbol Sc representing outlet identification information. Here, the symbol Sc is a two-dimensional code having information in the horizontal and vertical directions. The reading unit 233 is configured to read the outlet identification information from the symbol Sc provided on the outlet 211 in a contact or non-contact manner. Specifically, the reading unit 233 is configured to read the outlet identification information based on an image of the symbol Sc captured by a camera provided in the power data management device 23. The reading unit 233 outputs the read outlet identification information to the power data acquisition unit 231 as outlet identification data.

[0049] When the power data acquisition unit 231 receives the outlet identification data, the power data acquisition unit 231 may link the outlet identification data to the power data acquired from the power meter 22 and the vehicle identifier data accepted from the first vehicle identifier acquisition unit 234, and store this in the power data storage unit 232. Furthermore, the power consumption calculation unit 33 may link the outlet identification data when calculating the power consumption of the vehicle V in the driving test.

[0050] Next, an electricity consumption measurement operation using the electricity consumption measurement system 100 of this embodiment will be described with reference to the flow chart of FIG.

[0051] (1) Road test process First, a running test of the vehicle V is performed. Specifically, the completed vehicle V stored in a soak room in a fully charged state is moved to a test room and set on the chassis dynamometer 1 (step S1). The two-dimensional code attached to the vehicle V is photographed by the camera of the power data management device 23 to read the vehicle identifier, which is then transferred to the running data management device (step S2). Then, the rollers 11 are controlled by the chassis dynamometer 1 to perform a running test on the vehicle V in a predetermined running mode (step S3). After the start of the mode running of the vehicle V, when the remaining battery charge of the vehicle V falls below a predetermined value, the mode running is terminated. Based on the cumulative number of rotations of the rollers 11 of the chassis dynamometer 1, the running distance of the vehicle V from the start to the end of the mode running is calculated, and is stored in association with the vehicle identifier obtained before the start of the running test (step S4). Note that, if the vehicle V is a PHV (plug-in hybrid car), the running test in step S3 is performed in a state where the operation of the engine of the vehicle V is stopped.

[0052] (2) Charging process Next, the vehicle V after the running test is charged to be fully charged again. Specifically, after the running test, the vehicle V on the chassis dynamometer 1 is moved to a soak room within a predetermined time and set in the charging equipment 21 (step S5). The two-dimensional code attached to the vehicle V is photographed by the camera of the power data management device 23 to read the vehicle identifier (step S6). Communication is established between the power meter 22 connected to the charging equipment 21 and the power data management device 23, and the power data management device 23 is operated to start integrating the amount of power by the power meter 22 (step S7). Then, the vehicle V is connected to the charging outlet 211 by a charging cable, and charging of the vehicle V is started (step S8). Thereafter, when the rate of change of the integrated amount of power measured by the power data management device 23 becomes less than a predetermined value and it is determined that the battery of the vehicle V is fully charged, the power data management device 23 is operated to end the integration of the amount of power by the power meter 22 (step S9). Then, the integrated amount of electric power from the start of the integration until the rate of change of the integrated amount of electric power becomes less than a predetermined value is stored in association with the vehicle identifier obtained before the start of charging (step S10).

[0053] (3)Electricity cost calculation process Finally, the electric power consumption of the vehicle V in the running test is calculated based on the measured mileage and the integrated power consumption. Specifically, communication is established between the power data management device 23 and the running test management device 3 to enable data transmission and reception. Then, the operator operates the running test management device 3 to select and acquire from the power data management device 23 the electric power data whose vehicle identifier matches the mileage data stored in the running test management device 3. The electric power data imported into the running test management device 3 is linked to the mileage data whose vehicle identifier matches (step S11). Then, when the operator operates the running test management device 3 to click a button such as "calculate electric power consumption" displayed on the display of the running test management device 3, the electric power consumption is calculated based on the mileage indicated by the mileage data and the amount of power indicated by the power data, which are linked to each other, and the calculation result is displayed (step S12).

[0054] According to the electricity consumption measurement system 100 of the present embodiment configured as described above, the electricity consumption calculation unit 33 is configured to automatically link the mileage data and the power data, so that the occurrence of data input errors caused by the operator manually inputting the power data can be reduced. In addition, both the power data and the mileage data are stored together with the vehicle identifier, and the electricity consumption calculation unit 33 links the mileage data and the power data that have the same vehicle identifier. Therefore, even if a driving test or charging is performed on multiple vehicles V and multiple power data and mileage data exist, it is possible to prevent the power data and mileage data of different vehicles V from being erroneously linked. This improves the accuracy of the electricity consumption calculation.
