Description

Technical Field

[0001] This utility model relates to a charging data acquisition and simulation device and a vehicle charging data acquisition and simulation system, and particularly to a charging data acquisition and simulation device for acquiring and displaying charging data such as current and voltage when charging electric vehicles and other vehicles, and a vehicle charging data acquisition and simulation system equipped with the charging data acquisition and simulation device. Background Technology

[0002] In recent years, with the rapid development of the new energy vehicle industry, new energy vehicles, represented by electric vehicles, have gained popularity among consumers, and their share in the automotive market has continued to increase. Under this trend, charging technology, as a key technology in the electric vehicle industry, is also constantly being developed and researched.

[0003] In charging technology, the charging efficiency of electric vehicles and other vehicles is one of the important indicators. In the past, when testing the charging efficiency of vehicles, the electricity meter was usually connected to the power grid and the power supply was measured over a certain period of time. At the same time, the actual charging amount in the vehicle during the same period was measured. The charging efficiency of the vehicle was obtained by dividing the charging amount by the power supply.

[0004] However, when measuring power supply data from the power grid and other power systems using electricity meters as in the past, the data obtained is limited to the amount of power supplied from the grid, resulting in a relatively singular data dimension. Furthermore, during actual charging, the power quality from the power grid and other power systems may fluctuate (e.g., voltage and current deviations, frequency and amplitude fluctuations), making it impossible to monitor the quality of multi-dimensional power supply data indicators from the power grid and other power systems in real time. This makes it difficult for automotive or charging pile developers to analyze and address these power quality variations and implement subsequent improvements.

[0005] On the other hand, in the production process of electric vehicles and other vehicles, in order to ensure the safety and reliability of the vehicles during charging, there is a need to test the charging status of the vehicles in the event of power grid power supply failures such as phase loss. Utility Model Content

[0006] This utility model was developed to solve the above-mentioned problems. Its purpose is to provide a charging data acquisition and simulation device that can collect charging data in multiple dimensions and simulate power grid power supply faults such as phase loss, and a vehicle charging data acquisition and simulation system equipped with the charging data acquisition and simulation device.

[0007] To achieve the above objectives, this utility model provides a charging data acquisition and simulation device, which receives power through an input port and outputs power to the outside through an output port. A master control switch is provided on the electrical connection line between the input port and the output port. The charging data acquisition and simulation device includes a detection component, a control component, and a display component. The input terminal of the detection component is connected between the input port and the output port and detects the electrical signal. The first input terminal of the control component is connected to the output terminal of the detection component, and the first output terminal of the control component is connected to the input terminal of the display component. The display component displays the electrical signal detected by the detection component. The charging data acquisition and simulation device also includes an analog switch, which is disposed on at least one of the phase line, neutral line, and ground line constituting the electrical connection line between the input port and the output port.

[0008] According to one embodiment of the present invention, the electrical signal may also include at least one of voltage signal, current signal, power signal, and energy signal.

[0009] According to one embodiment of the present invention, the charging data acquisition and simulation device may also have a housing, with the detection component and the control component disposed inside the housing, and the master control switch, the input port, the output port, the display component and the simulation switch disposed on the outer surface of the housing.

[0010] According to one embodiment of the present invention, the display component may be a touch display and equipped with an analog switch touch button. The output terminal of the display component is connected to the second input terminal of the control component, and the second output terminal of the control component is connected to the analog switch.

[0011] According to one embodiment of the present invention, the analog switch may include at least one of a relay and a contactor.

[0012] According to one embodiment of the present invention, multiple analog switches may be provided, with each analog switch being provided on the phase line, the neutral line, and the ground line constituting the electrical connection line.

[0013] According to one embodiment of the present invention, the charging data acquisition and simulation device may also include a transformer, and the input end of the detection component is connected between the input port and the output port via the transformer.

[0014] According to one embodiment of this utility model, the detection component may also be an AC sensor.

[0015] In addition, this utility model also provides a vehicle charging data acquisition and simulation system, characterized in that the vehicle charging data acquisition and simulation system comprises: the above-mentioned charging data acquisition and simulation device; and a vehicle, wherein the vehicle is connected to the output port of the charging data acquisition and simulation device.

[0016] According to one embodiment of the present invention, the vehicle may also include a vehicle charging detection component and a charging control component. The vehicle charging detection component detects the phase signal of the power from the charging data acquisition and simulation device. The charging control component is connected to the vehicle charging detection component and is input with the phase signal detected by the vehicle charging detection component to control the charging status of the vehicle.

[0017] According to the charging data acquisition and simulation device of this utility model, the current signal, voltage signal, and other electrical signals (power supply data) from the power grid and other power systems are detected by the detection component, and the magnitude of the electrical signals and their changes over time are displayed in real time on the display component via the control component. Therefore, compared with the previous method of using an energy meter to only obtain the power supply from the power grid, this device can monitor the quality of multi-dimensional charging data indicators from the power grid and other power systems in real time. Operators can intuitively and comprehensively obtain charging data and conduct response analysis and subsequent improvements based on changes in power quality. Furthermore, since the charging data acquisition and simulation device also has a simulation switch, operators can easily use the simulation switch to simulate power grid power supply faults such as phase loss, and test the charging status and other operational states of vehicles or charging piles under such fault conditions, which helps improve the safety and reliability of vehicles during charging.

[0030] Reference Figures 1-4 This document provides a detailed description of a charging data acquisition and simulation device 1000 according to one embodiment of the present invention. It should be noted that in the following drawings, identical or similar parts are labeled with the same or similar reference numerals. However, the drawings are schematic, and attention should be paid to the possibility that the ratios of various dimensions may differ from reality. Therefore, specific dimensions should be determined by referring to the following description. Furthermore, the drawings may include parts with different dimensional relationships or ratios.

[0031] like Figure 1 and Figure 2 As shown, the charging data acquisition and simulation device 1000 of this embodiment includes, for example, an input port 110, an output port 120, and a master control switch 100 disposed on the electrical connection line between the input port 110 and the output port 120. The charging data acquisition and simulation device 1000 receives power through the input port 110 and outputs power to the outside (e.g., a charging pile or vehicle) through the output port 120, and uses the master control switch 100 to switch between working and non-working states.

[0032] In this embodiment, the charging data acquisition and simulation device 1000 may include, for example, a detection component 130, a control component 140, and a display component 150. As an example, optionally, the input terminal 131 of the detection component 130 is connected between the input port 110 and the output port 120, and detects electrical signals from a power system such as the power grid. For example, the detection component 130 can be used to detect voltage signals and current signals, or it can be used to detect power signals and energy signals. The electrical signals detected by the detection component 130 are not particularly limited as long as they include at least one of voltage signals, current signals, power signals, and energy signals.

[0033] As an example, the detection component 130 may optionally include various known AC sensors, such as AC current sensors, AC voltage sensors, AC power sensors, and AC frequency sensors, or combinations thereof, depending on the actual measurement requirements. Furthermore, in some embodiments, the type of sensor in the detection component 130 may be an electromagnetic induction sensor, a Hall effect sensor, or a capacitive sensor, as long as it can detect the desired voltage signal, current signal, or other electrical signal; it is not particularly limited.

[0034] In the charging data acquisition and simulation device 1000 of this embodiment, such as Figure 2 As shown, the first input terminal 141 of the control unit 140 is connected, for example, to the output terminal 132 of the detection unit 130. Thus, the control unit 140 receives the desired electrical signal (e.g., voltage signal, current signal, etc.) detected by the detection unit 130 and performs data processing accordingly as needed. On the other hand, the first output terminal 142 of the control unit 140 is connected, for example, to the input terminal 151 of the display unit 150. Thus, the control unit 140 transmits the electrical signal detected by the detection unit 130 and processed accordingly to the display unit 150, and displays the electrical signal on the display unit 150.

[0035] Optionally, the control unit 140 can be, for example, a known microcontroller, microcomputer, PLC (Programmable Logic Controller), FPGA (Field Programmable Gate Array), and ASIC (Application-Specific Integrated Circuit), as well as other programmable circuits. It can also be a computer with a processor, memory, storage devices, I / O, etc. It should be noted that the control unit 140 only needs to be able to receive the desired electrical signal detected by the detection unit 130 and transmit it to the display unit 150 for display; its specific structure is not particularly limited.

[0036] As an example, the control unit 140 may optionally include a data acquisition card, as is known in the art, capable of receiving the desired electrical signal detected by the detection unit 130 from the detection unit 130. Alternatively, the control unit 140 may communicate with the display unit 150 via a communication method known in the art, such as CAN (Controller Area Network) communication or power line communication, thereby transmitting the electrical signal detected by the detection unit 130 to the display unit 150 for display.

[0037] Optionally, the display component 150 can be a display device known in the art, such as a liquid crystal display (LCD), a light-emitting diode display (LED), an organic light-emitting diode display (OLED), or a touch display. The display component 150 is not particularly limited as long as it can receive the electrical signals detected by the detection component 130 from the control component 140 and display them on the screen. Furthermore, if the display component 150 is a touch display, the operator can adjust and set the type and state of the electrical signals displayed on the screen by touching or performing other operations on the display component 150, as needed.

[0038] As an example, the control unit 140 may receive the electrical signal detected by the detection unit 130 in real time and send it to the display unit 150 to display the signal in real time. Alternatively, the control unit 140 may receive the electrical signal detected by the detection unit 130 at predetermined intervals (e.g., milliseconds or seconds) and send it to the display unit 150. Or, the control unit 140 may average the electrical signals received from the detection unit 130 within a predetermined period and send it to the display unit 150. The specific method is not particularly limited. Furthermore, for example, when the display unit 150 displays electrical signals such as current signals and voltage signals in real time, the display unit 150 can not only display the magnitude of the electrical signal in real time, but also display the waveform of the electrical signal over time in real time.

[0039] Furthermore, as for data processing performed by the control unit 140, for example, if the detection unit 130 only includes a voltage sensor and a current sensor, the control unit 140 may optionally obtain a corresponding power signal by multiplying the current signal detected by the current sensor with the voltage signal detected by the voltage sensor. Alternatively, the control unit 140 may optionally obtain an energy signal by performing time integration on the power signal.

[0040] In some embodiments, the charging data acquisition and simulation device 1000 may further include, for example, an analog switch 160. Figure 2As shown, the simulation switch 160 is a switch used to simulate power grid power supply faults such as phase loss. For example, it can be installed on the electrical connection line between input port 110 and output port 120. Specifically, the simulation switch 160 can be installed on at least one of the phase line, neutral line, and ground line constituting the electrical connection line. For example, by having a worker disconnect the predetermined simulation switch 160, the power supply to the specific line where the simulation switch 160 is installed is cut off, thereby simulating power grid power supply faults such as phase loss.

[0041] Optionally, for example, when the charging data acquisition and simulation device 1000 is used in a single-phase three-wire power system, the phase line L1, neutral line N, and ground line PE in the single-phase three-wire power system are respectively connected to the charging data acquisition and simulation device 1000. In this case, such as Figure 3 As shown, the analog switch 160 may include, for example, at least one of the following: a phase line analog switch 161 disposed on the phase line L1, a neutral line analog switch 162 disposed on the neutral line N, and a ground line analog switch 163 disposed on the ground line PE.

[0042] Alternatively, for example, when the charging data acquisition and simulation device 1000 is used in a three-phase five-wire power system, the first phase line L1, the second phase line L2, the third phase line L3, the neutral line N, and the ground line PE in the three-phase five-wire power system are respectively connected to the charging data acquisition and simulation device 1000. In this case, such as Figure 4 As shown, the analog switch 160 may include, for example, at least one of the following: a first phase line analog switch 161a disposed on the first phase line L1, a second phase line analog switch 161b disposed on the second phase line L2, a third phase line analog switch 161c disposed on the third phase line L3, a neutral line analog switch 162 disposed on the neutral line N, and a ground line analog switch 163 disposed on the ground line PE.

[0043] According to the charging data acquisition and simulation device 1000 of this embodiment, the detection component 130 detects electrical signals (power supply data) such as current signals and voltage signals from the power grid and other power systems, and the control component 140 displays the magnitude of the electrical signals and their changes over time on the display component 150 in real time. Therefore, compared to the conventional method of using an electricity meter to only obtain the power supply from the power grid, this device can monitor the quality of multi-dimensional charging data indicators from the power grid and other power systems in real time. Operators can intuitively and comprehensively obtain charging data and conduct response analysis and subsequent improvements based on changes in power quality. Furthermore, since the charging data acquisition and simulation device 1000 also includes a simulation switch 160, operators can conveniently use the simulation switch 160 to simulate power grid power supply faults such as phase loss, and test the charging status and other operational states of the vehicle or charging pile under such fault conditions, which helps improve the safety and reliability of the vehicle during charging.

[0044] Furthermore, in the charging data acquisition and simulation device 1000 of this embodiment, as an example, it is optional that, for instance, Figure 1 As shown, the charging data acquisition and simulation device 1000 also has a housing 200, which can be any shape such as a cuboid, cube, or cylinder.

[0045] In some embodiments, the detection component 130 and control component 140 of the charging data acquisition and simulation device 1000 are, for example, disposed inside the housing 200, thereby protecting the detection component 130 and control component 140 by the housing 200. Alternatively, the master switch 100, input port 110, output port 120, display component 150, and analog switch 160 of the charging data acquisition and simulation device 1000 are, for example, disposed on the outer surface of the housing 200, thereby allowing the operator to conveniently operate the master switch 100, input port 110, output port 120, and analog switch 160 from the outside and obtain relevant data of the desired electrical signal from the display component 150.

[0046] Furthermore, the master switch 100, input port 110, output port 120, display unit 150, and analog switch 160 can be respectively disposed on the same outer surface of the housing 200 or on different outer surfaces, and are not particularly limited thereto. Alternatively, if the display unit 150 is a touch display, the analog switch 160 can also be disposed inside the housing 200 as described later.

[0047] In this way, by arranging the various components of the charging data acquisition and simulation device 1000 in the housing 200, operators can easily move the charging data acquisition and simulation device 1000 to a suitable work site for use, which can help improve the utilization efficiency and measurement efficiency of the charging data acquisition and simulation device 1000.

[0048] In addition, as another example, in the charging data acquisition and simulation device 1000 of this embodiment, such as Figure 5 As shown, the display unit 150 is, for example, a touch display, and is provided with an analog switch touch button 150a. In this case, optionally, the display unit 150 also has an output terminal 152, and the control unit 140 also has a second input terminal 143 and a second output terminal 144, and the second input terminal 143 of the control unit 140 is connected to the output terminal 152 of the display unit 150, and the second output terminal 144 of the control unit 140 is connected to the analog switch 160.

[0049] As an example, alternatively, if an operator wants to simulate a power grid fault such as a phase loss and disconnects the simulation switch 160, the operator can perform a touch operation such as touching the corresponding simulation switch touch button 150a on the display unit 150. After receiving the touch operation from the operator, the display unit 150 generates an indication signal corresponding to the touch operation and sends it to the control unit 140. After receiving the indication signal corresponding to the touch operation, the control unit 140 controls the simulation switch 160 to disconnect the simulation switch 160 in response to the operator's touch operation. On the other hand, if the operator wants to stop simulating a power grid fault such as a phase loss and turns off the simulation switch 160, the operator only needs to operate the corresponding simulation switch touch button 150a on the display unit 150 again, and the display unit 150 will similarly generate an indication signal to cause the control unit 140 to control the simulation switch 160 to turn on.

[0050] It should be noted that the generation of indication signals by the display component 150 in response to the operator's touch operation, and the activation or deactivation of the analog switch 160 by the control component 140 based on the indication signals, can all be achieved through the functions of display devices and control devices known in the art, and are not particularly limited.

[0051] Furthermore, as an example, the analog switch touch button 150a provided on the display unit 150 can optionally correspond to one or more analog switches 160 respectively provided on at least one of the phase lines (phase line L1 in the case of single-phase three-wire system, and first phase line L1, second phase line L2, and third phase line L3 in the case of three-phase five-wire system), neutral line N, and ground line PE in the electrical connection lines constituting the charging data acquisition and simulation device 1000. Thus, operators can conveniently use the analog switch touch button 150a to disconnect or connect each analog switch 160 individually.

[0052] Alternatively, the analog switch 160 may be, for example, a relay or contactor known in the art, or a combination of a relay and a contactor. As described above, the analog switch 160 is controlled by the control unit 140 to open or close in response to the touch operation of the analog switch touch button 150a by the operator.

[0053] In this way, by providing a simulated switch touch button 150a on the display component 150, and controlling the simulated switch 160 via the display component 150 and the control component 140 to perform disconnect or connect actions corresponding to the operator's touch operation on the simulated switch touch button 150a, the simulated switch 160 can be placed inside the charging data acquisition and simulation device 1000 instead of being placed on the outer surface of the housing 200 of the charging data acquisition and simulation device 1000. This effectively prevents accidents such as electric shock caused by the operator directly operating the simulated switch 160 itself, and allows the operator to conveniently and safely disconnect or connect the simulated switch 160 via the simulated switch touch button 150a.

[0054] In addition, in the charging data acquisition and simulation device 1000 of this embodiment, as an example, it is optional that multiple analog switches 160 are provided, and analog switches 160 are provided for the phase lines (phase line L1 in the case of single-phase three-wire system, and first phase line L1, second phase line L2, and third phase line L3 in the case of three-phase five-wire system), neutral line N and ground line PE, respectively.

[0055] By designing the structure in this way, the operators can effectively increase their freedom when simulating power grid faults such as phase loss. It can conveniently and quickly simulate different power supply fault states, efficiently test the charging status of vehicles or charging piles under various power grid fault conditions such as phase loss, and further improve the safety and reliability of vehicles during charging.

[0056] Furthermore, in the charging data acquisition and simulation device 1000 of this embodiment, as another example, such as Figure 6 As shown, optionally, the charging data acquisition and simulation device 1000 may also include a transformer 170, and the input terminal 131 of the detection component 130 is connected between the input port 110 and the output port 120 via the transformer 170.

[0057] In this way, by connecting the input terminal 131 of the detection component 130 between the input port 110 and the output port 120 via the transformer 170, the transformer 170 can be used to step down the high voltage from the power grid and other power systems. This can effectively prevent the detection component 130 from being damaged and malfunctioning due to high voltage fluctuations from the power grid and other power systems, and can help improve the overall reliability of the charging data acquisition and simulation device 1000.

[0058] In addition, such as Figure 7 As shown, the charging data acquisition and simulation device 1000 of this embodiment can, for example, be used together with the vehicle 2000 to form a vehicle charging data acquisition and simulation system S. Optionally, the output port 120 of the charging data acquisition and simulation device 1000 of this embodiment can be directly or via a charging pile (not shown) to the vehicle 2000 to form a vehicle charging data acquisition and simulation system S.

[0059] The vehicle charging data acquisition and simulation system S configured in this way can achieve the same advantageous effects as the charging data acquisition and simulation device 1000 of this embodiment. In particular, when the vehicle charging data acquisition and simulation system S is configured using the charging data acquisition and simulation device 1000 of this embodiment, it is possible to acquire and monitor multi-dimensional data indicators of the actual charging power supplied to the vehicle 2000 in real time, and to more reliably and accurately measure the charging status of the vehicle 2000.

[0060] Alternatively, in some embodiments, the vehicle 2000 may optionally include a vehicle charging detection component 210 and a charging control component 220. The vehicle charging detection component 210 detects the phase signal of the power from the charging data acquisition and simulation device 1000, and the charging control component 220 is connected to the vehicle charging detection component 210 and is input with the phase signal detected by the vehicle charging detection component 210 to control the charging state of the vehicle.

[0061] As an example, the vehicle charging detection component 210 in vehicle 2000 may use a phase sensor known in the art, and is not particularly limited thereto. The charging control component 220 in vehicle 2000 may be composed of known microcontrollers, microcomputers, PLCs (Programmable Logic Controllers), FPGAs (Field Programmable Gate Arrays), ASICs (Application-Specific Integrated Circuits), and other programmable circuits, similar to the control component 140 described above.

[0062] Furthermore, the desired charging state for the vehicle in the event of a power grid failure such as a phase loss is set as follows: (1) In the case of using a single-phase three-wire power system, if any one of the phase line L1, neutral line N, and ground line PE fails and disconnects, the charging control unit 220 cuts off the power supply from the power grid and other power systems, causing the vehicle to stop charging; (2) In the case of using a three-phase five-wire power system, if only one of the first phase line L1, second phase line L2, and third phase line L3 fails and disconnects, the charging control unit 220 disconnects one of the two phases that did not fail. The charging control unit 220 switches the vehicle's charging state to single-phase charging using only the phase line that is not faulty and not disconnected. If any two of the first phase line L1, the second phase line L2, or the third phase line L3 are faulty and disconnected, the charging control unit 220 switches the vehicle's charging state to single-phase charging using only the phase line that is not faulty. If all of the first phase line L1, the second phase line L2, and the third phase line L3 are faulty and disconnected, or if any of the neutral line N or the ground line PE are faulty and disconnected, the charging control unit 220 cuts off the power supply from the power grid or other power systems, causing the vehicle to stop charging.

[0063] The vehicle charging data acquisition and simulation system S, which consists of the charging data acquisition and simulation device 1000 of this embodiment and the vehicle 2000, can simulate various power grid power supply faults such as phase loss, and detect whether the vehicle 2000 to be tested performs the charging operation in the manner set above.

[0064] Specifically, as an example, an operator can operate the target analog switch 160 directly or via the analog switch touch button 150a, causing the power supply to a specific circuit containing the target analog switch 160 to be cut off, thus creating a phase loss fault (i.e., a phase loss fault in the power from the charging data acquisition and simulation device 1000). In this case, the vehicle charging detection unit 210 in the vehicle 2000 detects the phase signal of the power from the charging data acquisition and simulation device 1000 and inputs the detection result to the charging control unit 220, which then controls the charging status of the vehicle.

[0065] Optionally, operators can, for example, determine whether the charging control unit 220 in vehicle 2000 switches the vehicle's charging state to the charging state set above in accordance with the phase loss fault simulated by the operator. This allows the operator to test the vehicle's charging state and other operational states under the condition of a phase loss or other power grid power supply fault.
