Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile startup control method, device, equipment and storage medium. Background Art

[0002] With the popularity of electric vehicles, charging piles are also being rapidly constructed and installed to meet the charging needs of electric vehicles. When the charging pile is used in a low temperature environment, the charging pile may not be able to start normally due to the low ambient temperature. At present, the charging pile is mainly preheated by installing an auxiliary heating device inside the charging pile. Charging is performed after the temperature of the charging components inside the charging pile is raised. However, the installation of a heating device will increase the loss of the electric heat conversion of the charging pile, which increases the operating cost and also causes energy waste. The heating device also needs to occupy a certain space, making the space layout inside the charging pile box compact.

[0042] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0043] Reference Figure 1 , Figure 1This is a schematic diagram of the structure of a charging pile startup control device in the hardware operating environment involved in an embodiment of the present invention.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0045] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the charging pile start control device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0046] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a charging pile startup control program.

[0047] exist Figure 1 In the charging pile start-up control device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the charging pile start-up control device of the present invention can be set in the charging pile start-up control device, and the charging pile start-up control device calls the charging pile start-up control program stored in the memory 1005 through the processor 1001, and executes the charging pile start-up control method provided by the embodiment of the present invention.

[0048] The embodiment of the present invention provides a charging pile startup control method, wherein a vent is provided on the body of the charging pile, and an angle-adjustable closing device is provided on the vent. Figure 2 , Figure 2It is a flow chart of the first embodiment of the charging pile startup control method of the present invention.

[0049] In this embodiment, the charging pile startup control method includes the following steps:

[0050] Step S10: Obtain the internal temperature of the charging pile.

[0051] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a control device, a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a charging pile start control device, etc. The following takes the charging pile start control device (referred to as the control device) as an example to illustrate this embodiment and the following embodiments.

[0052] In this embodiment, the heat exchange between the vents provided on the charging pile body and the external environment can be adjusted by adjusting the angle between the closing device and the charging pile box; the charging pile can establish a charging connection with the vehicle through a charging gun; the internal temperature can be the temperature inside the charging pile box, and the internal temperature can be obtained through N temperature detection points set in the charging pile. In order to improve the accuracy of the internal temperature, a number of temperature detection points can be set in the power conversion module of the charging pile, and the average temperature detected by each temperature detection point is used as the internal temperature of the charging pile.

[0053] Step S20: When the internal temperature is less than or equal to the heating temperature threshold, controlling the closing device to close the vent to form a closed space in the charging pile.

[0054] It is understandable that the heating temperature threshold may be a pre-set temperature threshold for heating the charging pile, and if the internal temperature of the charging pile is less than or equal to the heating temperature threshold, it is determined that the power conversion module in the charging pile cannot charge the vehicle. That is, when the internal temperature of the charging pile is less than or equal to the heating temperature threshold, the charging pile is in a waiting mode or a non-starting mode.

[0055] In this embodiment, controlling the closing device to close the vent may be controlling the closing device to rotate a preset angle to close the vent; the preset angle may be a pre-set angle at which the closing device completely covers the vent; in this embodiment, a rotating shaft may be provided on the closing device, and the rotating shaft may be driven to rotate by a motor, thereby driving the closing device to rotate; after the closing device closes the vent, an enclosed space is formed inside the charging pile, and the heat exchange between the inside of the charging pile and the external environment is reduced, and the heat generated by the internal resistance of the charging pile gathers in the enclosed space, so that the internal temperature of the charging pile can rise rapidly.

[0056] Step S30: The enclosed space is heated by the heat generated by the internal resistance of the charging pile, and when the temperature in the enclosed space is greater than the charging temperature threshold, the closing device is controlled to open the vent.

[0057] It can be understood that the charging temperature threshold can be a pre-set temperature threshold at which the charging pile can charge at full power; if the internal temperature of the charging pile is lower than the charging temperature threshold, the power conversion module in the charging pile cannot charge at full power; controlling the closing device to open the vents can be controlling the closing device to rotate to a preset ventilation angle so that the charging pile can dissipate heat through the vents; the preset ventilation angle can be a pre-set angle between the closing device and the casing of the charging pile.

[0058] In this embodiment, the current weather information can also be obtained, and the closing device is controlled to rotate the ventilation angle corresponding to the current weather information; when the current weather information is sunny, in order to increase the heat dissipation, the closing device is controlled to rotate the first preset angle. After the closing device rotates the first preset angle, the angle between the closing device and the outer box of the charging pile is an obtuse angle, that is, the vent is opened upward, and the hot air flows upward, making it easier for the charging pile to dissipate heat; when the current weather information is rainy, snowy or dusty weather, in order to prevent rain, snow or dust from entering the box of the charging pile and causing damage to the charging pile, the closing device is controlled to rotate the second preset angle. After the closing device rotates the second preset angle, the angle between the closing device and the outer box of the charging pile is an acute angle, that is, the vent is opened downward, preventing rain, snow or dust from entering the box through the vent; when the current weather information is cloudy and rainy, the closing device is controlled to rotate the third preset angle. After the closing device rotates the third preset angle, the angle between the closing device and the outer box of the charging pile is a right angle, while preventing rain from entering the box of the charging pile, the heat dissipation of the charging pile is guaranteed.

[0059] In a specific implementation, a vent is provided on the body of the charging pile, and a closing device with an adjustable angle is provided on the vent. The angle of the closing device can be adjusted by controlling a motor to drive a rotating shaft of the closing device to rotate. A number of detection temperatures are obtained by temperature detection points arranged on the power conversion module, and the average temperature of the several detection temperatures is taken as the internal temperature of the charging pile. When the internal temperature is less than or equal to the heating temperature threshold, the closing device is controlled by a motor to close the vent to form an enclosed space inside the charging pile. The heat generated by the internal resistance of the charging pile gathers in the enclosed space, causing the internal temperature of the charging pile to rise rapidly. When the internal temperature of the charging pile rises to the charging temperature threshold, the current weather information is obtained, and the closing device is controlled to rotate to an angle corresponding to the current weather information to open the vent for heat dissipation.

[0060] Furthermore, in order to enable the charging pile to start normally in a low-temperature environment without setting a heating device inside the charging pile, the step S30 includes: in the process of heating the enclosed space by the heat generated by the internal resistance of the charging pile, obtaining the space temperature in the enclosed space; when the space temperature is greater than the heating temperature threshold and less than or equal to the charging temperature threshold, the charging pile enters a low-power heating mode; when the charging pile is in the low-power heating mode, the charging power of the charging pile increases with the increase of the space temperature; when the space temperature is greater than the charging temperature threshold, controlling the closing device to rotate to a preset heat dissipation position to open the vent for heat dissipation.

[0061] It is understandable that the low-power heating mode may be an operating mode in which the output power of the charging pile gradually increases as the temperature of the space rises until the output power increases to full power. The charging temperature threshold may be a temperature threshold at which charging can be output at full power. The full power may be the rated output power of the charging pile. The preset heat dissipation position may be a pre-set position in which the closing device opens the vents at a certain angle for heat dissipation.

[0062] It should be noted that the charging pile startup control method proposed in this embodiment determines whether the internal temperature of the charging pile meets the normal power startup of the power conversion module in the initial stage of charging. If the internal temperature of the charging pile is less than or equal to the heating temperature threshold, it is determined that the power conversion module cannot be started with normal power. At this time, the internal heat accumulation mode is entered, that is, the closing device is controlled to close the vent to form a closed space inside the charging pile. As the internal temperature of the charging pile rises, the conversion efficiency of the power conversion module gradually increases. When the internal temperature of the charging pile rises to the charging temperature threshold, the power conversion module can turn on the full load power to charge the vehicle. While there is no need to set a heating device inside the charging pile, it solves the problem that the charging pile cannot be started normally to charge the vehicle in an extremely cold environment. Compared with the existing technical solutions, the application cost is lower. The rotation angle of the closing device set at the vent can also be determined according to the current weather information to be suitable for applications in various extreme environments (such as sandstorms, heavy rains, typhoons, etc.).

[0063] In a specific implementation, a vent for heat dissipation is provided on the charging pile body, and a closing device with an adjustable angle is provided on the vent. When the vent is closed, a closed space is formed inside the charging pile. When the charging pile body is powered on, some electrical appliances (such as a control panel, a relay, and a display screen, etc.) inside the charging pile body are in a state of continuous energized operation, and the power loss of these electrical appliances themselves will generate a certain amount of heat. The power conversion module is in a power-off or low-temperature standby state when the charging pile does not supply power to the vehicle. When the internal temperature of the charging pile is less than or equal to the heating temperature threshold, the control closing device closes the vent. At this time, a closed space is formed inside the charging pile for heat accumulation. The accumulated heat is gradually conducted to the power conversion module in the power-off or low-temperature standby state in the charging pile body. When the temperature of the power conversion module reaches the charging temperature threshold, the power conversion module is put into normal charging operation (that is, the conversion power of the power conversion module increases with the increase of temperature), and the power conversion module also emits heat. At this time, the control closing device opens the vent for heat dissipation. A temperature detection point is provided on the charging pile body, and the control device can obtain the temperature information of each temperature detection point in real time, and determine the internal temperature of the charging pile according to the temperature information of each temperature detection point.

[0064] This embodiment proposes a charging pile startup control method, wherein a vent is provided on the body of the charging pile, and a closing device with an adjustable angle is provided on the vent, and the method comprises: obtaining the internal temperature of the charging pile; when the internal temperature is less than or equal to the heating temperature threshold, controlling the closing device to close the vent to form a closed space in the charging pile; heating the closed space by the heat generated by the internal resistance of the charging pile, and when the temperature in the closed space is greater than the charging temperature threshold, controlling the closing device to open the vent. In this embodiment, when the internal temperature of the charging pile is less than or equal to the heating temperature threshold, the closing device is controlled to close the vent to form a closed space in the charging pile, and the heat generated by the internal resistance of the charging pile is accumulated in the closed space, so that the temperature in the closed space rises, and when the temperature rises to the charging temperature threshold, the closing device is controlled to open the vent for heat dissipation, and the low-temperature startup of the charging pile can be achieved by adjusting the angle of the closing device and the internal resistance of the charging pile, without adding a heating device inside the charging pile, and the cost of the charging pile is reduced while achieving the low-temperature startup of the charging pile.

[0065] refer to Figure 3 , Figure 3 This is a flow chart of a second embodiment of a charging pile startup control method according to the present invention.

[0066] Based on the above embodiments, in this embodiment, step S10 includes:

[0067] Step S101: when a remote charging instruction is received or the charging time interval is preset, the power supply temperature is collected by a temperature sensor provided on each power supply module;

[0068] It is understandable that the remote charging instruction may be a scheduled charging instruction sent remotely by a user through a terminal device. The preset charging time interval may be a preset charging peak time. The power module may be a power conversion module in a charging pile.

[0069] It should be understood that the power supply temperature can be the temperature of the power conversion module; the power module can also be called the power conversion module; at least one temperature detection point is provided on each power module in the charging pile to detect the temperature of different power modules respectively, and the power modules in the charging pile are arranged vertically with the upper and lower sides facing each other (or other arrangements suitable for heat conduction), and the specific arrangement order can be from bottom to top, namely, power module N, temperature detection point, power module N+1, temperature detection point, power module N+2, temperature detection point, etc. For charging piles with flexible allocation functions, low-temperature startup can be selectively performed by accurately detecting the temperature of each power module. For example, if only two 10kw power modules are currently needed, it is only necessary to monitor the startup temperature of these two power modules.

[0070] Step S102: determining the internal temperature of the charging pile according to the collected power supply temperature.

[0071] In this embodiment, in order to improve the accuracy of monitoring, the power module that needs to enter the working state can be determined, the power supply temperature can be obtained through the temperature detection point corresponding to the power supply module that needs to enter the working state, and the average temperature value of the obtained power supply temperature is used as the internal temperature of the charging pile.

[0072] Furthermore, in order to reduce the cost of the charging pile, the step S10 further includes: when the charging connection between the charging pile and the vehicle is established, collecting the internal temperature of the charging pile by means of a temperature sensor disposed inside the charging pile.

[0073] In a specific implementation, the charging pile is connected to the vehicle, and after determining that the connection and communication with the vehicle are normal, the charging connection between the charging pile and the vehicle is established. Several temperatures are collected through the power conversion module, vents and temperature sensors installed on the box inside the charging pile, and the internal temperature of the charging pile is determined based on the average temperature of the several temperatures.

[0074] Furthermore, in order to reduce the cost of the charging pile, when the charging connection between the charging pile and the vehicle is established, after the internal temperature of the charging pile is collected by a temperature sensor arranged inside the charging pile, it also includes: when the internal temperature is greater than the charging temperature threshold, controlling the closing device to open the vent, and controlling the charging pile to charge the vehicle at full power.

[0075] In some implementations, for example, the heating temperature threshold is T1, the internal temperature of the charging pile is T0, and the charging temperature threshold is T2. Assuming that T1 is -40 degrees Celsius and T2 is -25 degrees Celsius, at least two temperature sensors are set on the power conversion module in the charging pile, and at least two sampled temperatures are obtained by the at least two temperature sensors. The lowest sampled temperature of the at least two sampled temperatures is used as the internal temperature of the charging pile. Figure 4 , Figure 4 The figure is a flow chart for controlling the startup of a charging pile in a low-temperature environment. When the charging connection between the charging pile and the vehicle is established, charging is started, and the temperature inside the charging pile is detected. When the internal temperature of the charging pile is less than -40 degrees Celsius, the charging pile enters a waiting mode / no-start mode, and the closing device is controlled to close the vents on the charging pile to form a closed space inside the charging pile. The internal resistance of the charging pile generates heat that accumulates in the closed space, and the internal temperature of the charging pile (i.e., the spatial temperature of the closed space) gradually increases. When the internal temperature T0 of the charging pile is greater than or equal to -40 degrees Celsius and less than -25 degrees Celsius, the charging pile enters a low-power heating mode. During the process of increasing the internal temperature of the charging pile, the output power of the power conversion module gradually increases. When the internal temperature of the charging pile is greater than -25 degrees Celsius, the charging pile enters a normal working mode to charge the vehicle at full power, and the closing device is controlled to rotate to a preset heat dissipation position to open the vents for heat dissipation.

[0076] This embodiment collects the power supply temperature through the temperature sensor set on each power module when receiving a remote charging command or in a preset charging time interval; and determines the internal temperature of the charging pile according to the collected power supply temperature. This embodiment can obtain the internal temperature of the charging pile when receiving a remote charging command or in a preset charging time interval, and when the internal temperature of the charging pile is less than or equal to the charging temperature threshold, close the vent in advance to allow the power conversion module to heat up, thereby ensuring that in a low temperature environment, the vehicle can be charged at normal power without waiting after being plugged in, thereby improving the user experience.

[0077] refer to Figure 5 , Figure 5 It is a flow chart of the third embodiment of the charging pile startup control method of the present invention.

[0078] Based on the first embodiment above, in this embodiment, after step S30, the method further includes:

[0079] Step S40: Obtaining the ambient humidity and ambient temperature of the environment in which the charging pile is located.

[0080] In this embodiment, an ambient humidity detection point and an ambient temperature detection point can be set outside the charging pile, and the ambient humidity of the environment in which the charging pile is located can be obtained through the ambient humidity detection point, and the ambient temperature of the environment in which the charging pile is located can be obtained through the ambient temperature detection point.

[0081] Step S50: determining a dew point temperature according to the ambient humidity and the ambient temperature, and determining a temperature difference according to the internal temperature and the ambient temperature.

[0082] It can be understood that, according to the ambient humidity and ambient temperature, the dew point temperature corresponding to the ambient humidity and ambient temperature can be found in the dew point temperature mapping relationship table; the dew point temperature mapping relationship table can be a chart storing the correspondence between ambient humidity, ambient temperature and dew point temperature; the temperature difference is obtained by subtracting the ambient temperature from the internal temperature of the charging pile.

[0083] Step S60: adjusting the angle of the closing device according to the dew point temperature and the temperature difference.

[0084] It can be understood that adjusting the angle of the closing device according to the dew point temperature and the temperature difference can be to compare the dew point temperature with the temperature difference, determine whether condensation exists based on the comparison result, and when there is no condensation, adjust the angle of the closing device according to the weather information; when there is condensation, control the angle of the closing device to be adjusted to a preset drainage angle to discharge the water generated by condensation out of the charging pile box; the preset drainage angle can be a pre-set angle at which the closing device can discharge the water generated by condensation out of the charging pile box, and the preset drainage angle is an acute angle.

[0085] Furthermore, in order to prevent water generated by condensation from flowing into the interior of the charging pile, the step S60 includes: when the temperature difference is less than or equal to the dew point temperature, adjusting the angle between the closing device and the outer box of the charging pile to an acute angle; and when the temperature difference is greater than the dew point temperature, adjusting the angle between the closing device and the outer box of the charging pile to a right angle or an obtuse angle.

[0086] It can be understood that in order to ensure the heat dissipation while preventing the moisture generated by condensation from flowing into the interior of the charging pile box, the final angle between the closing device and the charging pile box can be determined according to the absolute value of the difference between the temperature difference and the dew point temperature and the internal temperature of the charging pile, and the rotation of the closing device is controlled according to the final angle.

[0087] In a specific implementation, when the temperature difference is less than or equal to the dew point temperature, it is determined that condensation exists, the absolute value of the difference between the temperature difference and the dew point temperature and the current internal temperature of the charging pile are obtained, the final angle between the closing device and the box is determined by formula 1, and the rotation of the closing device is controlled according to the final angle, wherein formula 1 can be expressed as: α=a / |Ta-Tb|+k*Tc, wherein α is the final angle, Ta is the temperature difference, Tb is the dew point temperature, Tc is the current internal temperature, a is an integer greater than 10 and less than 50, and k is a constant greater than 0 and less than 1.

[0088] In some implementations, when the temperature difference is greater than the dew point temperature, it is determined that there is no condensation, and the closing device is controlled to rotate, and the angle between the lower surface of the rotating closing device and the outer box of the charging pile is a right angle or an obtuse angle.

[0089] It should be noted that the closing device provided on the vent can specifically refer to the structure of the shutters. The angle between the closing device and the box body of the charging pile can be adjusted by a motor. An ambient humidity detection point (used to detect the ambient humidity outside the charging pile) and an ambient temperature detection point (used to detect the ambient temperature outside the charging pile) are provided on the outside of the charging pile body. When the charging pile is working normally, the internal temperature of the charging pile is higher than the ambient temperature. There is a temperature difference between the internal temperature of the charging pile and the ambient temperature. When the temperature difference is lower than the dew point temperature under the ambient humidity conditions, condensation will occur at the vent. In order to prevent the water generated by condensation from flowing into the box body of the charging pile, the shutters of the closing device need to tilt downward, that is, the angle between the shutters and the outer box body of the charging pile is an acute angle, so as to discharge the moisture generated by condensation to the outside. Conversely, when the temperature difference is higher than the dew point temperature under the humidity conditions, in order to speed up the discharge of heat, the shutters of the closing device need to tilt upward or horizontally discharge the hot air in the charging pile, that is, the angle between the closing device and the outer box body of the charging pile is an obtuse angle or a right angle.

[0090] This embodiment obtains the ambient humidity and ambient temperature of the environment in which the charging pile is located; determines the dew point temperature according to the ambient humidity and the ambient temperature, and determines the temperature difference according to the internal temperature and the ambient temperature; and adjusts the angle of the closing device according to the dew point temperature and the temperature difference. This embodiment adjusts the angle of the closing device by the temperature difference and the dew point temperature, thereby preventing water generated by condensation from flowing into the box of the charging pile, causing damage to the charging pile, and improving the safety of the charging pile.

[0091] In addition, an embodiment of the present invention further proposes a storage medium, on which a charging pile startup control program is stored. When the charging pile startup control program is executed by a processor, the steps of the charging pile startup control method described above are implemented.

[0092] Reference Figure 6 , Figure 6 This is a structural block diagram of the first embodiment of the charging pile startup control device of the present invention. The main body of the charging pile is provided with a vent, and the vent is provided with a closing device with an adjustable angle.

[0093] like Figure 6 As shown, the charging pile startup control device proposed in the embodiment of the present invention includes:

[0094] An acquisition module 10 is used to acquire the internal temperature of the charging pile;

[0095] A control module 20, configured to control the closing device to close the vent to form a closed space in the charging pile when the internal temperature is less than or equal to a heating temperature threshold;

[0096] The control module 20 is further used to heat the enclosed space through the heat generated by the internal resistance of the charging pile, and control the closing device to open the vent when the temperature in the enclosed space is greater than the charging temperature threshold.

[0097] In this embodiment, when the internal temperature of the charging pile is less than or equal to the heating temperature threshold, the closed device is controlled.

[0098] The vents are closed to form a closed space in the charging pile. The heat generated by the internal resistance of the charging pile is accumulated in the closed space, causing the temperature in the closed space to rise.

[0099] When the charging temperature threshold is reached, the closing device is controlled to open the vents for heat dissipation. The low-temperature start of the charging pile can be achieved by adjusting the angle of the closing device and the internal resistance of the charging pile. There is no need to add a heating device inside the charging pile. This reduces the cost of the charging pile while achieving low-temperature start-up of the charging pile.

[0100] Based on the first embodiment of the charging pile startup control device of the present invention, a second embodiment of the charging pile startup control device of the present invention is proposed.

[0101] In this embodiment, the control module 20 is further used to obtain the space temperature in the enclosed space during the process of heating the enclosed space by the heat generated by the internal resistance of the charging pile;

[0102] When the space temperature is greater than the heating temperature threshold and less than or equal to the charging temperature threshold, the charging pile enters the low-power heating mode; when the charging pile is in the low-power heating mode, the charging pile

[0103] The charging power of the electric pile increases as the temperature of the space increases; when the temperature of the space is greater than the charging temperature threshold, the closing device is controlled to rotate to a preset heat dissipation position to open the vent for heat dissipation.

[0104] The acquisition module 10 is also used to collect the power supply temperature through the temperature sensor set on each power supply module when receiving a remote charging instruction or in a preset charging time zone 0; and determine the internal temperature of the charging pile based on the collected power supply temperature.

[0105] The acquisition module 10 is further configured to collect the internal temperature of the charging pile through a temperature sensor disposed inside the charging pile when the charging connection between the charging pile and the vehicle is established.

[0106] The control module 20 is further configured to control the closing device to open the vent when the internal temperature is greater than a charging temperature threshold, and to control the charging pile to charge the vehicle at full power.

[0107] The control module 20 is also used to obtain the ambient humidity and ambient temperature of the environment in which the charging pile is located; determine the dew point temperature according to the ambient humidity and the ambient temperature, and determine the dew point temperature according to the internal temperature

[0108] and determining a temperature difference with the ambient temperature; and adjusting the angle of the closing device 0 according to the dew point temperature and the temperature difference.

[0109] The control module 20 is also used to adjust the angle between the closing device and the outer box of the charging pile to an acute angle when the temperature difference is less than or equal to the dew point temperature; and to adjust the angle between the closing device and the outer box of the charging pile to a right angle or an obtuse angle when the temperature difference is greater than the dew point temperature.
