Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle teaching, and particularly to a simulation system and method for the charging strategy of a DC charging pile. Background Art

[0002] At the present stage, the automotive industry has developed rapidly, especially the rise of new energy and pure electric vehicle technologies. With the rapid development of the automotive industry, automotive vocational education has also received great attention.

[0003] Currently, the convenience of driving is one of the important factors affecting the popularization of new energy electric vehicles. During driving, it is necessary to consider the remaining battery power of the vehicle and the problem of convenient charging. Existing DC charging piles and AC charging piles on the market provide charging services for new energy electric vehicles. Among them, the AC electric vehicle charging pile, commonly known as "slow charging", is fixedly installed outside the electric vehicle and connected to the AC power grid to provide AC power for the on-vehicle charger of the electric vehicle (i.e., the charger fixedly installed on the electric vehicle); the DC electric vehicle charging station, commonly known as "fast charging", is fixedly installed outside the electric vehicle and connected to the AC power grid, and can provide DC power for the non-vehicle-mounted power battery of the electric vehicle. During actual driving, new energy electric vehicles usually choose DC charging piles for fast charging.

[0004] As the charging speed increases, the current and voltage will also increase linearly, which easily causes extremely high heat to be generated during the charging process of the DC charging pile. Moreover, due to environmental characteristics such as region, season, and weather, the DC charging pile has extremely high requirements for humidity. If the humidity is not removed and heat is not dissipated in time, it will accelerate the aging of the equipment, reduce the service life of the DC charging pile, and even seriously endanger the safe operation of the DC charging pile.

[0005] Regarding the safe DC charging strategy for electric vehicles, especially the process of removing humidity and dissipating heat during the charging of the DC charging pile, considering that the currently used DC charging pile has too high a voltage level and a large size, it is not conducive to directly transporting it to the classroom for explanation and training. It is often necessary to organize students to an off-campus site for explanation, which is time-consuming and laborious. Moreover, directly improving the DC charging pile to solve the problem of removing humidity and dissipating heat has a high cost and a low safety factor, and it is difficult to ensure the personal safety of teachers and students. Summary of the Invention

[0038] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0040] Embodiment 1

[0041] The moisture removal and heat dissipation of existing DC charging piles are divided into two parts: module moisture removal and heat dissipation and overall chassis moisture removal and heat dissipation. Since the charging modules are built into the charging piles, the protection measures are mainly reflected in the design of the overall chassis moisture removal and heat dissipation. Usually, the air inlet and outlet of the box are made into a louver type, and a fan is installed at the air outlet to discharge heat through the fan, so as to play a certain protective role.

[0042] Considering that the voltage level of the currently used DC charging piles is too high and the equipment is huge, it is not conducive to directly moving them to the classroom for explanation and training. Moreover, it is complex, costly, and has a low safety factor to explain the DC charging strategy directly on the DC charging pile, making it difficult to ensure the personal safety of teachers and students. Therefore, this embodiment provides a DC charging pile charging strategy simulation system, as Figure 1 shown, which includes a heating and humidification simulation module, a temperature and humidity acquisition module, a season selection module, a data processing and control module, a heat dissipation simulation module, and a display module.

[0043] Among them, the heating and humidification simulation module is used to simulate the heating and humidification inside the DC charging pile. The temperature and humidity acquisition module is electrically connected to the data processing and control module, and is used to collect real-time temperature and humidity data and upload the collected real-time temperature and humidity data to the data processing and control module. Considering the large volume of the on-site DC charging pile equipment, which is not convenient for carrying and displaying, the temperature and humidity acquisition module set in this embodiment of the system uses a temperature and humidity sensor. The heating and humidification simulation module includes a hair dryer, wet tissue, etc. The temperature and humidity sensor is set inside the shell of the simulated DC charging pile to collect temperature and humidity. The inside of the shell is heated by the hot air of the hair dryer to simulate the overheating state of the DC charging pile. The wet tissue is placed on the temperature and humidity sensor to simulate the over-wet state inside the DC charging pile, so as to realize the simulation of the temperature and humidity change of the DC charging pile.

[0044] The above-mentioned season selection module is electrically connected to the data processing and control module, and is used to select different seasons and upload the selected season information to the data processing and control module, so as to simulate the moisture removal and heat dissipation conditions during the charging of the DC charging pile in different seasons through the season selection module; the above-mentioned heat dissipation simulation module is used to simulate the heat dissipation of the charging pile, and a small fan can be driven for heat dissipation simulation. In this embodiment, the small fan is set on the shell of the simulated DC charging pile.

[0045] The above-mentioned data processing and control module is used to receive the real-time temperature and humidity data and the selected season information, and control the output of the simulated charging current value of the DC charging pile and the heat dissipation simulation drive level according to the real-time temperature and humidity data, the preset humidity threshold, and the multi-level temperature threshold range corresponding to the selected season; the heat dissipation simulation module performs the heat dissipation simulation of the charging pile according to the received heat dissipation simulation drive level.

[0046] Further, regardless of the season set by the season selection module, when the real-time humidity is greater than the preset humidity threshold, the output DC charging pile simulated charging current value is controlled to be 0, and the heat dissipation simulation drive level is controlled to be high, that is, the heat dissipation simulation module is driven to operate at the highest power for heat dissipation; when the real-time humidity is less than the preset humidity value, the temperature is judged according to the real-time temperature and the multi-level temperature threshold interval corresponding to the selected season.

[0047] Further, different seasons correspond to different multi-level temperature threshold intervals. According to the multi-level temperature threshold interval corresponding to the selected season, judge the temperature threshold interval where the real-time temperature is located, and determine and output the DC charging pile simulated charging current value and the heat dissipation simulation drive level based on the DC charging pile simulated charging current value and the heat dissipation simulation drive level corresponding to the temperature threshold interval. Taking the selected season as spring as an example, a six-level temperature threshold interval is set, including: ≤35°C, 35°C ≤ 42°C, 42°C ≤ 50°C, 50°C ≤ 55°C, 55°C ≤ 60°C, and >60°C. As shown in Table 1 below, when the real-time temperature ≤ 35°C, the output DC charging pile simulated charging current value is 115A - 120A, and the output heat dissipation simulation drive level is low; when 35°C ≤ real-time temperature ≤ 42°C, the output DC charging pile simulated charging current value is 95A - 100A, and the output heat dissipation simulation drive level is medium; when 42°C ≤ real-time temperature ≤ 50°C, the output DC charging pile simulated charging current value is 75A - 80A, and the output heat dissipation simulation drive level is medium; when 50°C ≤ real-time temperature ≤ 55°C, the output DC charging pile simulated charging current value is 55A - 60A, and the output heat dissipation simulation drive level is high; when 55°C ≤ real-time temperature ≤ 60°C, the output DC charging pile simulated charging current value is 35A - 40A, and the output heat dissipation simulation drive level is high; when the real-time temperature > 60°C, the output DC charging pile simulated charging current value is 0A, and the output heat dissipation simulation drive level is high.

[0050] In this embodiment, by selecting the dehumidification and heat dissipation conditions in different seasons of spring, summer, autumn, and winter, the authenticity and reliability of the simulation are guaranteed. Similarly, this embodiment gives the multi-level temperature threshold intervals when the selected seasons are summer, autumn, and winter as shown in Tables 2, 3, and 4 below, and the corresponding output DC charging pile simulated charging current values and heat dissipation simulation drive levels.

[0057] As another implementation, it further includes a heat dissipation simulation adjustment module for manually adjusting the heat dissipation simulation drive level and outputting the heat dissipation simulation drive level to the heat dissipation simulation module, that is, by manually adjusting the three - speed rotation speed or power of the small fan.

[0058] As another implementation, it further includes a dehumidification simulation module for simulating the dehumidification of the charging pile. The dehumidification simulation can be carried out by driving the small fan. The control method of this dehumidification simulation module is the same as that of the above - mentioned heat dissipation simulation module.

[0059] The above - mentioned display module is electrically connected to the data processing and control module, and is used to display the real - time temperature and humidity data received by the data processing and control module and the selected season information. At the same time, it also displays the simulated charging current value of the DC charging pile and the heat dissipation simulation drive level output by the data processing and control module in real time. By displaying the real - time temperature and humidity through the display module, the change of the temperature and humidity inside the DC charging pile under different simulation conditions can be intuitively observed. Specifically, when the temperature inside the DC charging pile is too high, the control principle of automatically increasing the rotation speed gear of the heat dissipation fan and reducing the output current at the same time to reduce heat generation and ensure the safe operation of the DC charging pile is simulated. Through the displayed data, different dehumidification and heat dissipation schemes and effects of the DC charging pile under different temperature and humidity conditions can be more intuitively understood, ensuring the safety of the staff and experimental equipment during the simulation experiment, and being more convenient for daily teaching work.

[0060] In addition, the system described in this embodiment further includes a power supply module for supplying power to each module.

[0061] As another implementation, the system described in this embodiment further includes a data storage module. This data storage module is electrically connected to the data processing and control module and is used to store the real - time temperature and humidity data received by the data processing and control module and the selected season information. At the same time, it correspondingly stores the simulated charging current value of the DC charging pile and the heat dissipation simulation drive level output by the data processing and control module in real time. In this embodiment, the data is synchronously stored in an Excel spreadsheet, ensuring the integrity of the simulation experiment data. Students can more intuitively understand different dehumidification and heat dissipation schemes and effects of the DC charging pile under different temperature and humidity conditions through the data in Excel.

[0062] The system described in this embodiment can simulate the principle of timely dehumidification and heat dissipation during the charging of a DC charging pile by changing the fan speed under different seasons, temperatures, and humidities through a small number of devices and simple settings. It can be directly transported to the classroom for explanation and training, facilitating learners to more intuitively understand the charging strategy of the DC charging pile, improving the training effect of DC charging pile operation and maintenance, enriching the teaching form, with low cost and high safety factor.
