It is connected and fixed to the side of the shelf board 41. Thereby, in the mounting base 40, shelf boards 41 can be connected by the connection board 43, and it can prevent that this shelf boards 41 shift | deviate mutually. When disassembling the mounting table 40, first, after removing all the connection plates 43, each shelf plate 41 may be removed.

  Further, the mounting table 40 is provided with wheels 44 at the four corners of the lower surface of the shelf 41 located at the bottom. By providing these wheels 44, the mounting table 40 can be easily moved.

  The shelf board 41 is provided with two handle portions 45 side by side at each end in the longitudinal direction. Thus, as will be described later, when the shelf board 41 of the mounting table 40 is disassembled, the shelf board 41 can be easily carried and the disassembling work of the mounting table 40 can be performed efficiently. In the present embodiment, as shown in FIG. 4, in the mounting table 40, the shelf 41 positioned at the top is provided with a large handle portion.

  The configuration of the mounting table 50 is the same as that of the mounting table 40 described above except that all the columns 52 have the same length and the shelves 51 are arranged at the same interval. Is omitted. In FIG. 4, reference numeral 53 is a connection plate for connecting the shelf boards 51, reference numeral 54 is a wheel, and reference numeral 55 is a handle provided on each shelf board 51.

  In addition to the charging device 5 disposed on the bottom shelf 41, the mounting table 40 includes a switch box 15 having disconnection test switches 15a to 15c, a DC power supply unit 19, a leakage test unit 20, and a power switching unit. 14 and a resistor 18 are arranged. In addition, the quick charger connection portion 11 a and the normal charger connection portion 11 b are attached to the shelf 41 so as to be located on the side of the mount 40. Specifically, the quick charger connecting portion 11a and the ordinary charger connecting portion 11b are provided on different shelf boards 41, and between the two handle parts 45, 45 in each shelf board 41. Is arranged. Furthermore, a computer that functions as the charging evaluation control unit 13 is also arranged on the mounting table 40. This computer is, for example, a general-purpose computer with a display screen. In this embodiment, the sensor signal output unit 17 shown in FIG. 1 is arranged in the switch box 15.

  The bottom shelf plate 41 of the mounting table 40 on which the charging device 5 is disposed is provided with a hole 41a through which a cooling pipe 61 for supplying cooling water to the charging device 5 is inserted. The cooling pipe 61 is connected to a pump 62 disposed in an external water tank 60. Thereby, the water in the water tank 60 sent by the pump 62 flows into the charging device 5 through the cooling pipe 61 and cools the charging device 5.

  A plurality of electronic loads 12 are arranged on the mounting table 50. These electronic loads 12 are separately arranged on each shelf board 51. The electronic load 12 arranged on the mounting table 50 is connected to the resistor 18 arranged on the mounting table 40 by a DC power line 21. In the present embodiment, five electronic loads 12 are provided. However, the number is not limited to this, and may be four or less, or may be six or more.

  In addition, in this embodiment, although each component of the charging evaluation apparatus 1 for moving bodies is divided and arrange | positioned on the mounting bases 40 and 50, it is not this limitation, A component is arrange | positioned on one mounting base. Alternatively, it may be divided into three or more mounting tables.

(Operation of charging system and charging evaluation device for moving body)
Next, when evaluating the charging system 10 including the charger 4 and the charging device 5 using the mobile charging evaluation device 1 having the above-described configuration, the charging system 10 and the moving body The operation of the charging evaluation device 1 will be described.

  First, when the power supply of the mobile charging evaluation apparatus 1 is turned on, the mobile charging evaluation apparatus 1 selects rapid charging or normal charging. The selection of the charging mode is performed, for example, by an input operation to a computer that functions as the charging evaluation control unit 13.

  In addition, you may perform selection of the above-mentioned charge mode based on the connection of the charger 4 with respect to the charge evaluation apparatus 1 for mobile bodies. That is, when the charger 4 is connected to one of the quick charger connection portion 11a and the normal charger connection portion 11b in the mobile charging evaluation device 1, the connection is detected by the charge evaluation control portion 13. The charging mode in the mobile charging evaluation apparatus 1 may be switched. In such a configuration, whether the charger 4 is connected to the quick charger connection portion 11a or the normal charger connection portion 11b may be determined based on a fitting signal described later.

<For quick charging>
First, the operations of the charging system 10 and the mobile charging evaluation apparatus 1 during rapid charging will be described with reference to FIGS. 5A and 5B.

  As shown in FIG. 5A, the evaluation start switch (SW) of the mobile charging evaluation apparatus 1 is turned on by an input operation or the like on the computer (SA1). Thereby, in the charge evaluation control part 13 comprised virtually in a computer, it will be in a charge start preparation state (SA2). This charge start preparation state means that the charge evaluation control unit 13 enters a standby state so that a charge start signal can be output to the charging device 5 as described later.

  Thereafter, by connecting the quick charger side connector of the quick charger 70 to the quick charger connection portion 11a (SA3), a fitting signal is output from the quick charger 70 to the charging device 5 (SA4). When receiving the fitting signal, the charging device 5 detects that the connection portion of the quick charger 70 is electrically connected (SA5).

  Further, when the charging start switch of the quick charger 70 is turned on (SA6), preparation for starting charging is started in the quick charger 70 (SA7). This charge start preparation means that the quick charger 70 is in a standby state so that power can be supplied. The quick charger 70 outputs a start pressing signal to the charging device 5 after preparation for starting charging (SA8). When the charging device 5 receives the start pressing signal (SA9), the charging device 5 outputs the start pressing signal to the charging evaluation control unit 13 (SA10). When the charging evaluation control unit 13 receives the start pressing signal (SA11), it outputs a charging start signal to the charging device 5 (SA12).

  Note that the charging evaluation control unit 13 may be configured to output a charging start signal to the charging device 5 when the charging start is turned on by an input to the computer, for example.

  When the charging device 5 receives the charging start signal from the charging evaluation control unit 13 (SA13), the charging device 5 transmits / receives a charging information signal to / from the quick charger 70, and performs charging with the quick charger 70. Necessary information is exchanged (SA14, SA15). Here, the information necessary for charging is, for example, output power of the quick charger 70 or the like.

  The quick charger 70 performs an insulation test when the transmission / reception of the charging information signal to / from the charging device 5 is completed (SA16). In this insulation test, it is detected whether the DC power line 21 is grounded.

  The quick charger 70 outputs a supply start signal to the charging device 5 after the end of the insulation test (SA17). Thereafter, the quick charger 70 starts supplying charging power to the mobile charging evaluation apparatus 1 (SA18). On the other hand, the charging device 5 that has received the supply start signal from the quick charger 70 (SA19) turns on the first relay unit 14a and the second relay unit 14b of the power switching unit 14 (SA20).

  As a result, the charging power supplied from the quick charger 70 to the mobile charging evaluation apparatus 1 is supplied to the electronic load 12 via the power switching unit 14, and therefore, the mobile charging evaluation apparatus 1 uses the electric vehicle. 2 can simulate the state of charge.

  When charging is stopped in the mobile charging evaluation apparatus 1, a charging stop signal is output from the charging evaluation control unit 13 to the charging apparatus 5 as shown in FIG. 5B (SA21). The charge evaluation control unit 13 may be configured to output a charge stop signal after a predetermined time has elapsed after outputting the above charge start signal, or according to an operation on the computer. May be output.

  When the charging device 5 receives a charge stop signal from the charge evaluation control unit 13 (SA22), it outputs a supply stop signal to the quick charger 70 (SA23). Then, the charging device 5 turns off the first relay unit 14a and the second relay unit 14b of the power switching unit 14 (SA24). On the other hand, in the quick charger 70 that has received the supply stop signal from the charging device 5 (SA25), the supply of charging power to the mobile charging evaluation device 1 is stopped (SA26).

  Thereby, the supply of electric power from the quick charger 70 to the electronic load 12 in the mobile charging evaluation apparatus 1 is stopped.

  Thereafter, when the quick charger side connector of the quick charger 70 is separated from the quick charger connecting portion 11a of the mobile charging evaluation apparatus 1 (SA27), a fitting signal is input from the quick charger 70 to the charging device 5. Therefore, the charging device 5 detects that it is in a non-fitted state (SA28).

  The charging evaluation control unit 13 outputs the evaluation result on the computer screen after the above-described operation is completed (SA29). An example of the items displayed on the charge evaluation control unit 13 and the evaluation results are shown in FIGS. In this embodiment, as shown in FIGS. 6 and 7, the charging evaluation control unit 13 detects the power supply voltage, charging power, charging current, charging voltage, charging abnormality flag, charging error code, and the like of the charging device 5. ing. In the present embodiment, these values are output from the charging device 5 to the charging evaluation control unit 13 by a CAN signal.

  Moreover, in this embodiment, the charge evaluation control part 13 has detected each above-mentioned item in each area (each state) shown by I-VII at the left end of FIG. 5A and FIG. 5B. These sections have a plurality of the entire period of the above-described charging operation (a period from when the evaluation start switch is turned on in the charging evaluation control unit 13 until the evaluation result is displayed in the charging evaluation control unit 13). In this embodiment, it is obtained by dividing into 7) as an example. Note that the number of sections and the range of sections shown in FIGS. 5A and 5B are examples, and other sections and sections may be used, or may be set as appropriate by the charging evaluation control unit 13. .

  In the example of the present embodiment, the section I is from when the evaluation start switch is turned on in the charging evaluation control unit 13 until the quick charger side connector of the quick charger 70 is connected to the quick charger connection unit 11a. Between. Section II is after section I until the charging start switch is turned on by quick charger 70. Section III is a period after section II until the charging device 5 receives a charging start signal. Section IV is after section III until charging device 5 receives a supply start signal. The section V is a period after the section IV until the charging device 5 receives the charge stop signal. Section VI is a period after section V until the quick charger side connector of the quick charger 70 is separated from the quick charger connecting portion 11a. The section VII is a period until the evaluation result is displayed by the charging evaluation control unit 13 after the section VI.

  Each section described above is determined by the charging evaluation control unit 13 detecting a signal (charging status signal) transmitted from the charging device 5.

  The charging evaluation control unit 13 determines whether or not these detection results are within a preset reference range based on the detection results as shown in FIG. An example of the result is shown in FIG. In FIG. 7, a circle indicates a case where the detection result is within the reference range, a mark X indicates a case where the detection result is outside the reference range, and a case where the hatched portion is not determined. Note that the above-described determination may be performed for each sampling point in each section, or may be performed using an average value of consecutive sampling points.

  An example of the case where the above-described determination result is displayed on the display screen of the computer is shown in FIG. In the example shown in FIG. 8, the determination result of each determination item is displayed as a signal. That is, in FIG. 8, if the detection result is within the reference range, the signal display portion is lit in, for example, green (indicated by hatching in FIG. 8), while if the detection result is out of the reference range, the signal display is performed. The portion is lit in red (not shown), for example. In addition, when a detection result is not obtained or when determination is not performed, the signal display portion is not lit (white circle in FIG. 8). In FIG. 8, BAT indicates the power supply voltage of the charging device 5, CHGPWR indicates charging power, and CHGCUR indicates the charging current.

  In the example of FIG. 8, if all the detection results for each item are within the reference range, the characters “PASS” are displayed. On the other hand, if at least one of the detection results of each item is out of the reference range, “FAIL” is displayed.

  By displaying the determination result as shown in FIG. 8, the operator can easily grasp the determination result by the mobile charging evaluation apparatus 1.

  In the present embodiment, the charging evaluation control unit 13 detects and determines the power supply voltage, charging power, charging current, charging voltage, charging abnormality flag, charging error code, and the like of the charging device 5. However, the present invention is not limited to this, and other values related to charging control of the charging system 10 may be detected and determined, or only detection may be performed. In the present embodiment, a display example of the determination result is shown, but the detection result may be displayed. Furthermore, the charging evaluation control unit 13 may detect input / output signals of the charging device 5 in addition to the power supply voltage, charging power, charging current, charging voltage, charging abnormality flag, and charging error code of the charging device 5.

  Further, the disconnection test switches 15a to 15c provided in the mobile charging evaluation apparatus 1 are operated so that various signals are not transmitted between the charging apparatus 5 and the quick charger 70. Good. By doing so, the mobile charging evaluation apparatus 1 can detect the state of charge at that time.

<For normal charging>
Next, operations of the charging system 10 and the mobile charging evaluation apparatus 1 during normal charging will be described with reference to FIG.

  As in the case of quick charging, the evaluation start switch of the mobile charging evaluation apparatus 1 is turned on by screen input or the like on the computer (SB1). Thereby, in the charge evaluation control part 13, it will be in a charge start preparation state (SB2). This charge start preparation state means that the charge evaluation control unit 13 enters a standby state so that a charge start signal can be output to the charging device 5 as described later.

  Thereafter, the normal charger-side connector of the normal charger 80 is connected to the normal charger connecting portion 11b (SB3), whereby a fitting signal is output from the normal charger 80 to the charging device 5 (SB4). When receiving the fitting signal, the charging device 5 detects that the normal charger side connector of the normal charger 80 is electrically connected to the normal charger connecting portion 11b (SB5).

  The normal charger 80 outputs a fitting signal to the charging device 5, and then outputs a power information signal to the charging device 5 (SB6). This power supply information signal is a signal related to the output of the power supply. The power supply information signal output from the normal charger 80 is received by the charging device 5 (SB7).

  On the other hand, when the charging evaluation control unit 13 detects that the fitting signal is output from the normal charger 80 to the charging device 5, it outputs a charging start signal to the charging device 5 (SB8).

  The charging evaluation control unit 13 may be configured to output a charging start signal to the charging device 5 when the charging start is turned on by an input to a computer, for example, or a signal other than the fitting signal ( For example, when a power supply information signal) is detected, a charging start signal may be output to the charging device 5.

  When the charging device 5 receives the charging start signal (SB9), the second relay unit 14b is turned on (SB10). Thereafter, the charging device 5 outputs a supply start signal to the normal charger 80 (SB11).

  The normal charger 80 that has received the supply start signal from the charging device 5 (SB12) starts supplying AC charging power to the charging device 5 (SB13).

  Here, in the case of normal charging, AC charging power supplied from the normal charger 80 is converted to DC in the charging device 5 and boosted to a predetermined voltage. Therefore, as described above, by turning on the second relay unit 14b, the charging power converted into direct current by the charging device 5 is supplied to the electronic load 12. Thereby, it becomes possible to simulate the charging state in the case of normal charging in the electric vehicle 2.

  When charging is stopped in the mobile charging evaluation apparatus 1, the charging evaluation control unit 13 outputs a charging stop signal to the charging apparatus 5 (SB14). The charge evaluation control unit 13 may be configured to output a charge stop signal after a predetermined time has elapsed after outputting the above charge start signal, or according to an operation on the computer. May be output.

  When the charging device 5 receives the charge stop signal from the charge evaluation control unit 13 (SB15), it outputs a supply stop signal to the normal charger 80 (SB16). Then, the second relay unit 14b of the power switching unit 14 is turned off from the charging device 5 (SB17). On the other hand, the normal charger 80 that has received the supply stop signal from the charging device 5 (SB18) stops the supply of charging power to the mobile charging evaluation device 1 (SB19).

  Thereby, the supply of electric power from the ordinary charger 80 to the electronic load 12 in the mobile charging evaluation apparatus 1 is stopped.

  Thereafter, when the ordinary charger side connector of the ordinary charger 80 is separated from the ordinary charger connection portion 11b of the mobile charging evaluation apparatus 1 (SB20), the fitting device outputs a fitting signal output from the ordinary charger 80. 5, the charging device 5 detects that it is in a non-fitted state (SB21).

  As in the case of the quick charge described above, the charge evaluation control unit 13 outputs the evaluation result to the computer screen after the above-described operation is completed (SB22). In the case of normal charging, there are parts that differ in operation from the case of rapid charging, such as the fact that AC power for charging supplied to the charging device 5 is detected by the power quality monitor 16. Therefore, items detected and determined by the charging evaluation control unit 13 are slightly different from those in the case of rapid charging.

  In the case of the present embodiment, as shown in FIGS. 10 and 11, the charging evaluation control unit 13 includes the power supply voltage, the charging power, the charging current, the charging voltage, the AC input voltage, the charging abnormality flag, and the charging device 5. A charging error code or the like is detected. Note that the charging evaluation control unit 13 may detect an input / output signal of the charging device 5 in addition to the power supply voltage, charging power, charging current, charging voltage, charging abnormality flag, and charging error code of the charging device 5.

  Even in the case of normal charging, as in the case of rapid charging, the charging evaluation control unit 13 detects each item described above in each section (each state) indicated by I to VI on the left end of FIG. The number of sections and the range of sections shown in FIG. 9 are merely examples, and the number of sections and the range of sections other than this may be used, and may be set as appropriate by the charging evaluation control unit 13.

  In the example of the present embodiment, the section I is from when the evaluation start switch is turned on in the charging evaluation control unit 13 until the ordinary charger side connector of the ordinary charger 80 is connected to the ordinary charger connection unit 11b. Between. Section II is after section I until charging device 5 receives the charging start signal. Section III is a period after section II until the charging device 5 outputs a supply start signal. Section IV is a period after section III until the charging device 5 receives a charge stop signal. Section V is a period after section IV until the ordinary charger side connector of the ordinary charger 80 is separated from the ordinary charger connecting portion 11b. The section VI is a period after the section V until the evaluation result is displayed by the charging evaluation control unit 13.

  Each section described above is determined by the charging evaluation control unit 13 detecting a signal (charging status signal) transmitted from the charging device 5.

  Even in the case of normal charging, as in the case of quick charging, the charging evaluation control unit 13 determines whether or not those detection results are within a preset reference range based on the detection results shown in FIG. An example of the result is shown in FIG. In FIG. 11, a circle indicates a case where the detection result is within the reference range, a mark X indicates a case where the detection result is outside the reference range, and a case where the hatched portion is not determined. Note that the above-described determination may be performed for each sampling point in each section, or may be performed using an average value of consecutive sampling points.

  The determination result in FIG. 11 is output to the screen as shown in FIG. 8, for example, as in the case of the quick charge. As in the case of rapid charging, other values related to charging control of the charging system 10 may be detected and determined, or only detection may be performed. Further, the detection result may be displayed.

  Further, the disconnection test switches 15 a to 15 c provided in the mobile charging evaluation apparatus 1 are operated so as to simulate a state in which various signals are not transmitted between the charging apparatus 5 and the normal charger 80. Good. By doing so, the mobile charging evaluation apparatus 1 can detect the state of charge at that time.

(Effects of the first embodiment)
As described above, in this embodiment, the charging system 7 constituted by the charger 4 and the electric vehicle 2 can be reproduced using the mobile charging evaluation apparatus 1. This makes it possible to simulate a charging system for charging the electric vehicle 2 without using the actual electric vehicle 2. Therefore, the charging state of the charging system can be evaluated without using the actual electric vehicle 2. Therefore, the charging system can be evaluated using the mobile charging evaluation apparatus 1 even in a remote place or a remote place.

  Moreover, the mobile charging evaluation apparatus 1 can detect various data when the charging apparatus 5 mounted on the electric vehicle 2 performs a charging operation. Therefore, it becomes possible to easily grasp the state in the charging system in the charging operation of the electric vehicle 2 by the mobile charging evaluation apparatus 1.

  In the mobile charging evaluation apparatus 1, the charging evaluation control unit 13 is provided with a determination unit 32 that determines whether the detected data is within the reference range. By outputting and displaying the determination result, the operator can easily recognize the state of charge.

  Furthermore, the mobile charging evaluation apparatus 1 includes disconnection test switches 15a to 15c for connecting and disconnecting the quick charge control signal line 22, the normal charge control signal line 23, and the control signal line 26, respectively. Therefore, in the mobile charging evaluation apparatus 1, it is possible to reproduce the case where each signal line is disconnected or the case where no signal is input to the charging apparatus 5. Therefore, the mobile charging evaluation apparatus 1 can reproduce various charging states and detect and evaluate data in those states.

  The mobile charging evaluation apparatus 1 of the first embodiment includes a quick charging circuit and a normal charging circuit so that both quick charging and normal charging can be supported. Therefore, as compared with the case where different devices are used according to the charging mode, the charging evaluation device for the electric vehicle 2 can be downsized and the convenience can be improved.
