Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a control method, device and electronic equipment for a synchronous cooling system for a vehicle and a charging pile. Background Technology

[0002] With the increasing popularity of electric vehicles, users have higher demands for vehicle safety, practicality, and stability. Among these, the charging status of vehicles affects the user experience and energy conversion efficiency, and has always been a major concern. To meet the growing needs of users, high-power, high-current charging piles are gradually being used, which can improve charging efficiency, but at the same time generate a lot of heat. If not handled properly, this may threaten the safety and stability of the charging pile and the electric vehicle. Therefore, it is essential to cool down the charging pile and the electric vehicle in a reasonable and efficient manner.

[0003] Among related technologies, liquid-cooled charging technology mainly involves connecting a liquid cooling system inside the charging pile or vehicle, and using this liquid cooling system to independently cool and dissipate heat from the charging pile or vehicle.

[0004] However, by independently cooling the charging pile or the vehicle, the cooling efficiency of the charging pile or the vehicle is reduced, thereby affecting the safety and stability of the vehicle and the charging pile. Summary of the Invention

[0005] This application provides a control method, device, and electronic equipment for a synchronous cooling system for vehicles and charging piles, in order to solve the problems of reduced heat dissipation efficiency due to independent heat dissipation of vehicles or charging piles, which in turn affects the safety and stability of vehicles and charging piles.

[0006] The first aspect of this application provides a control method for a vehicle and charging pile synchronous cooling system. The vehicle and charging pile synchronous cooling system includes a temperature acquisition component, a charging gun, a charging pile liquid cooling system, and a vehicle liquid cooling system. The temperature acquisition component is disposed in the vehicle's charging system. One end of the charging system is connected to the charging gun, and the other end is connected to a battery pack. The charging pile liquid cooling system includes a liquid cooling tank and a first liquid cooling pipe. The liquid cooling tank includes coolant. One end of the first liquid cooling pipe is connected to the liquid cooling tank, and the other end is connected to a second liquid cooling pipe inside the charging gun. The vehicle liquid cooling system consists of a charging harness with a third liquid cooling pipe. One end of the third liquid cooling pipe is connected to the second liquid cooling pipe, and the other end is connected to the charging system. The method includes the following steps:

[0007] Determine whether the vehicle and the charging station generate a cooling signal;

[0008] If the vehicle and the charging pile generate the cooling signal, the liquid cooling system of the charging pile is controlled to start based on the cooling signal, so that the coolant in the liquid cooling tank flows into the first liquid cooling pipe, the second liquid cooling pipe and the third liquid cooling pipe in sequence, so as to cool down the vehicle and the charging pile by means of liquid circulation.

[0009] According to one embodiment of this application, determining whether the vehicle and the charging pile generate a cooling signal includes:

[0010] Collect first temperature data of the charging gun and the charging system and second temperature data of the charging system and the battery pack, and receive third temperature data of the charging pile;

[0011] Determine whether the first temperature data is greater than a first preset temperature threshold, or whether the second temperature data is greater than the first preset temperature threshold, or whether the third temperature data is greater than the first preset temperature threshold;

[0012] If the first temperature data is greater than the first preset temperature threshold, or the second temperature data is greater than the first preset temperature threshold, or the third temperature data is greater than the first preset temperature threshold, then the cooling signal is generated.

[0013] According to one embodiment of this application, after controlling the cooling of the vehicle and the charging pile using the liquid circulation method, the process includes:

[0014] Collect the fourth temperature data of the charging gun and the charging system and the fifth temperature data of the charging system and the battery pack, and receive the sixth temperature data of the charging pile;

[0015] Determine whether the fourth temperature data is less than or equal to the second preset temperature threshold, or whether the fifth temperature data is less than or equal to the second preset temperature threshold, or whether the sixth temperature data is less than or equal to the second preset temperature threshold;

[0016] If the fourth temperature data is less than or equal to the second preset temperature threshold, or the fifth temperature data is less than or equal to the second preset temperature threshold, or the sixth temperature data is less than or equal to the second preset temperature threshold, then the liquid cooling system of the charging pile is controlled to shut down.

[0017] According to one embodiment of this application, after collecting fourth temperature data of the charging gun and the charging system and fifth temperature data of the charging system and the battery pack, and receiving sixth temperature data of the charging pile, the method further includes:

[0018] If the fourth temperature data is greater than the first preset temperature threshold, or the fifth temperature data is greater than the first preset temperature threshold, or the sixth temperature data is greater than the first preset temperature threshold, then the charging pile liquid cooling system is determined to be in a fault state.

[0022] According to the control method of the vehicle and charging pile synchronous cooling system in this application embodiment, it is determined whether the vehicle and charging pile generate a cooling signal. If the vehicle and charging pile generate a cooling signal, the charging pile liquid cooling system is activated based on the cooling signal. This allows the coolant in the liquid cooling tank to flow sequentially into the first liquid cooling pipe, the second liquid cooling pipe, and the third liquid cooling pipe, using liquid circulation to cool the vehicle and charging pile. This solves the problem of reduced heat dissipation efficiency due to independent heat dissipation of the vehicle or charging pile, which in turn affects the safety and stability of the vehicle and charging pile. By collecting the temperature of each connection point of the vehicle charging system, the charging pile liquid cooling system is activated when the temperature exceeds a set value. Liquid enters the liquid cooling pipes of the charging pile and the vehicle from the liquid cooling tank, achieving synchronous cooling of the vehicle and charging pile through liquid circulation, thereby improving the heat dissipation efficiency and safety of the vehicle and charging pile.

The vehicle and charging pile synchronous cooling system includes a temperature acquisition component, a charging gun, a charging pile liquid cooling system, and a vehicle liquid cooling system. The temperature acquisition component is disposed in the vehicle's charging system. One end of the charging system is connected to the charging gun, and the other end is connected to a battery pack. The charging pile liquid cooling system includes a liquid cooling tank and a first liquid cooling pipe. The liquid cooling tank includes coolant. One end of the first liquid cooling pipe is connected to the liquid cooling tank, and the other end is connected to a second liquid cooling pipe inside the charging gun. The vehicle liquid cooling system consists of a charging harness with a third liquid cooling pipe. One end of the third liquid cooling pipe is connected to the second liquid cooling pipe, and the other end is connected to the charging system. The device includes:

[0032] The second judgment unit is used to determine whether the fourth temperature data is less than or equal to the second preset temperature threshold, or whether the fifth temperature data is less than or equal to the second preset temperature threshold, or whether the sixth temperature data is less than or equal to the second preset temperature threshold.

[0033] The control unit is configured to shut down the liquid cooling system of the charging pile if the fourth temperature data is less than or equal to the second preset temperature threshold, or the fifth temperature data is less than or equal to the second preset temperature threshold, or the sixth temperature data is less than or equal to the second preset temperature threshold.

[0034] According to one embodiment of this application, after collecting fourth temperature data of the charging gun and the charging system and fifth temperature data of the charging system and the battery pack, and receiving sixth temperature data of the charging pile, the second acquisition unit further includes:

[0035] The determination subunit is used to determine that the charging pile liquid cooling system is in a fault state if the fourth temperature data is greater than the first preset temperature threshold, or the fifth temperature data is greater than the first preset temperature threshold, or the sixth temperature data is greater than the first preset temperature threshold.

[0036] According to one embodiment of this application, after determining that the charging pile liquid cooling system is in a fault state, the determination subunit further includes:

[0037] A generation sub-component is used to generate an acoustic alarm signal and / or an optical alarm signal of the charging pile liquid cooling system based on the fault state.

[0039] According to the control device of the vehicle and charging pile synchronous cooling system in this application embodiment, it determines whether the vehicle and charging pile generate a cooling signal. If the vehicle and charging pile generate a cooling signal, it controls the charging pile liquid cooling system to start based on the cooling signal, so that the coolant in the liquid cooling tank flows sequentially into the first liquid cooling pipe, the second liquid cooling pipe, and the third liquid cooling pipe, using liquid circulation to cool the vehicle and charging pile. This solves the problem of reduced heat dissipation efficiency due to independent heat dissipation of the vehicle or charging pile, which in turn affects the safety and stability of the vehicle and charging pile.

[0049] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0050] The control method, apparatus, and electronic equipment of a vehicle and charging pile synchronous cooling system according to embodiments of this application are described below with reference to the accompanying drawings. Addressing the problem mentioned in the background art where independent cooling of the vehicle or charging pile reduces heat dissipation efficiency, thus affecting the safety and stability of the vehicle and charging pile, this application provides a control method for a vehicle and charging pile synchronous cooling system. In this method, it is determined whether the vehicle and charging pile generate a cooling signal. If a cooling signal is generated, the charging pile liquid cooling system is activated based on the cooling signal, causing coolant in the liquid cooling tank to flow sequentially into the first, second, and third liquid cooling pipes, cooling the vehicle and charging pile through liquid circulation. This solves the problem of reduced heat dissipation efficiency due to independent cooling of the vehicle or charging pile, thus affecting the safety and stability of the vehicle and charging pile. By collecting the temperature at each connection point of the vehicle charging system, the charging pile liquid cooling system is activated when the temperature exceeds a set value. Liquid enters the liquid cooling pipes of the charging pile and vehicle from the liquid cooling tank, achieving synchronous cooling of the vehicle and charging pile through liquid circulation, thereby improving the heat dissipation efficiency and safety of the vehicle and charging pile.

[0051] Specifically, Figure 1 This is a flowchart illustrating a control method for a synchronous cooling system for a vehicle and a charging pile, as provided in an embodiment of this application.

[0052] like Figure 1 As shown, the vehicle and charging pile synchronous cooling system includes a temperature acquisition component, a charging gun, a charging pile liquid cooling system, and a vehicle liquid cooling system. The temperature acquisition component is installed in the vehicle's charging system. One end of the charging system is connected to the charging gun, and the other end is connected to the battery pack. The charging pile liquid cooling system includes a liquid cooling tank and a first liquid cooling pipe. The liquid cooling tank contains coolant. One end of the first liquid cooling pipe is connected to the liquid cooling tank, and the other end is connected to a second liquid cooling pipe inside the charging gun. The vehicle liquid cooling system consists of a charging harness with a third liquid cooling pipe. One end of the third liquid cooling pipe is connected to the second liquid cooling pipe, and the other end is connected to the charging system. The control method for this vehicle and charging pile synchronous cooling system includes the following steps:

[0053] In step S101, it is determined whether the vehicle and the charging pile generate a cooling signal.

[0054] According to one embodiment of this application, determining whether a vehicle and a charging pile generate a cooling signal includes: collecting first temperature data of the charging gun and the charging system and second temperature data of the charging system and the battery pack, and receiving third temperature data of the charging pile; determining whether the first temperature data is greater than a first preset temperature threshold, or whether the second temperature data is greater than the first preset temperature threshold, or whether the third temperature data is greater than the first preset temperature threshold; if the first temperature data is greater than the first preset temperature threshold, or the second temperature data is greater than the first preset temperature threshold, or the third temperature data is greater than the first preset temperature threshold, then a cooling signal is generated.

[0055] The first preset temperature threshold can be set by those skilled in the art according to actual testing needs, or it can be obtained through a limited number of computer simulations, and is not specifically limited here.

[0056] Specifically, in this embodiment of the application, in order to solve the problems of reduced heat dissipation efficiency due to independent heat dissipation of the vehicle or charging pile, and the inability to achieve synchronous cooling of the vehicle and charging pile, thereby affecting the safety and stability of the vehicle and charging pile, this embodiment of the application collects the temperature of each connection point of the vehicle charging system, and controls the start of the charging pile liquid cooling system when the temperature is greater than a set threshold. The coolant enters the liquid cooling pipes of the charging pile and the vehicle from the liquid cooling tank, so as to achieve synchronous cooling of the vehicle and the charging pile through liquid circulation, thereby improving the heat dissipation efficiency and safety of the vehicle and the charging pile.

[0057] Specifically, such as Figure 2As shown, the embodiments of this application mainly include a temperature detection system, a charging pile liquid cooling system, and a vehicle liquid cooling system. The temperature detection system includes a temperature acquisition component, i.e., a temperature sensor, which is installed in the charging system (mainly including a charging socket and connector) of the vehicle's high-voltage charging cable harness. One end of the charging system is connected to the charging gun, and the other end is connected to the battery pack. First, the temperature acquisition component continuously collects first temperature data at the connection point between the charging gun and the charging socket in the charging system, and second temperature data at the connection point between the connector and the battery pack in the charging system, and receives third temperature data sent by the charging pile in real time. Second, the collected and received temperature data are judged. If the first temperature data is greater than a first preset temperature threshold, or the second temperature data is greater than the first preset temperature threshold, or the third temperature data is greater than the first preset temperature threshold, it indicates that the vehicle or charging pile temperature is too high, which will affect the charging efficiency and the charging safety and stability of the vehicle and charging pile. Therefore, it is necessary to cool the vehicle and charging pile. At this time, the temperature acquisition component transmits the data to the VCU (Vehicle Control Unit) and BMS (Battery Management System). The battery management system and each charging interface send a start signal, i.e. a cooling signal, to the charging pile to cool down the vehicle and the charging pile.

[0058] In step S102, if the vehicle and the charging pile generate a cooling signal, the liquid cooling system of the charging pile is controlled to be turned on based on the cooling signal, so that the coolant in the liquid cooling tank flows into the first liquid cooling pipe, the second liquid cooling pipe and the third liquid cooling pipe in sequence, so as to cool down the vehicle and the charging pile by means of liquid circulation.

[0059] The charging pile liquid cooling system includes a cooling module, a liquid cooling box, and a first liquid cooling pipe. The liquid cooling box is placed inside the charging pile and contains the coolant required for cooling (including but not limited to water, ethylene glycol, silicone oil, etc.). One end of the first liquid cooling pipe (e.g., the liquid inlet end) is connected to the liquid cooling box, and the other end of the first liquid cooling pipe is connected to the second liquid cooling pipe inside the charging gun. The first liquid cooling pipe can be connected to the electric vehicle liquid cooling system through the charging gun. The cooling module is used to cool the coolant in the liquid cooling box. The vehicle liquid cooling system consists of a charging harness with a third liquid cooling pipe. The third liquid cooling pipe is located in the center of the charging harness and is uniformly wrapped with copper wire. One end of the third liquid cooling pipe (e.g., the liquid inlet end) is connected to the second liquid cooling pipe, and the other end of the third liquid cooling pipe is connected to the charging socket in the charging system.

[0060] Specifically, such as Figure 2As shown in this embodiment, when the vehicle and charging pile need to be cooled, the temperature acquisition component sends a cooling signal to the charging pile through the VCU, BMS, and each charging interface. After receiving the cooling signal, the charging pile controls the charging pile liquid cooling system to start, so that the coolant in the liquid cooling tank flows into the first liquid cooling pipe of the charging pile liquid cooling system, then flows through the second liquid cooling pipe in the charging gun into the third liquid cooling pipe of the vehicle liquid cooling system, then enters the charging socket in the charging system through the third liquid cooling pipe, then flows into the coolant tank through the cable, then flows through the vehicle charging system, and the heat is carried away by the coolant through heat transfer, and then returns to the charging pile through the outlet. Thus, the vehicle and charging pile are cooled by liquid circulation.

[0061] According to one embodiment of this application, after controlling the cooling of the vehicle and charging pile using a liquid circulation method, the process includes: collecting fourth temperature data of the charging gun and the charging system and fifth temperature data of the charging system and the battery pack, and receiving sixth temperature data of the charging pile; determining whether the fourth temperature data is less than or equal to a second preset temperature threshold, or whether the fifth temperature data is less than or equal to a second preset temperature threshold, or whether the sixth temperature data is less than or equal to a second preset temperature threshold; if the fourth temperature data is less than or equal to a second preset temperature threshold, or the fifth temperature data is less than or equal to a second preset temperature threshold, or the sixth temperature data is less than or equal to a second preset temperature threshold, then controlling the liquid cooling system of the charging pile to shut down.

[0062] The second preset temperature threshold can be set by those skilled in the art according to actual testing needs, or it can be obtained through a limited number of computer simulations, and is not specifically limited here.

[0063] Specifically, in this embodiment, after cooling the vehicle and charging pile through liquid circulation, the fourth temperature data at the connection between the charging gun and the charging socket in the charging system and the fifth temperature data at the connection between the connector and the battery pack in the charging system are collected, and the sixth temperature data sent by the charging pile is received. If the fourth temperature data is less than or equal to the second preset temperature threshold, or the fifth temperature data is less than or equal to the second preset temperature threshold, or the sixth temperature data is less than or equal to the second preset temperature threshold, it indicates that the temperature of the vehicle and charging pile has returned to normal, that is, below the second preset temperature threshold. At this time, the coolant returns to the liquid cooling tank, and the liquid cooling system of the charging pile is controlled to shut down.

[0064] According to one embodiment of this application, after collecting the fourth temperature data of the charging gun and the charging system and the fifth temperature data of the charging system and the battery pack, and receiving the sixth temperature data of the charging pile, the method further includes: if the fourth temperature data is greater than the first preset temperature threshold, or the fifth temperature data is greater than the first preset temperature threshold, or the sixth temperature data is greater than the first preset temperature threshold, then the liquid cooling system of the charging pile is determined to be in a fault state.

[0065] According to one embodiment of this application, after determining that the charging pile liquid cooling system is in a fault state, the method further includes: generating an acoustic alarm signal and / or an optical alarm signal for the charging pile liquid cooling system based on the fault state; performing an acoustic alarm on the charging pile liquid cooling system based on the acoustic alarm signal and / or performing an optical alarm on the charging pile liquid cooling system based on the optical alarm signal.

[0066] Specifically, in this embodiment, after cooling the vehicle and charging pile through liquid circulation, if the fourth temperature data collected at the connection between the charging gun and the charging socket in the charging system is greater than the first preset temperature threshold, or the fifth temperature data at the connection between the connector and the battery pack in the charging system is greater than the first preset temperature threshold, or the sixth temperature data received from the charging pile is greater than the first preset temperature threshold, it indicates that the charging pile liquid cooling system has malfunctioned. After cooling the vehicle and charging pile through the charging pile liquid cooling system, the fourth, fifth, and sixth temperature data have failed to be less than or equal to the second preset temperature threshold. Therefore, an alarm needs to be triggered for this malfunction.

[0067] Specifically, in this embodiment of the application, when the liquid cooling system of the charging pile malfunctions, an acoustic alarm can be triggered based on the acoustic alarm signal of the liquid cooling system, such as through a buzzer or voice broadcast device, and / or an optical alarm can be triggered based on the optical alarm signal of the liquid cooling system, such as an LED (Light-Emitting Diode) display. This alerts the user that the liquid cooling system is in an abnormal fault state and needs to be corrected in time, thereby ensuring the safety of the vehicle and the charging pile.

[0068] In summary, through the detailed discussion of the above embodiments, this application can achieve simultaneous cooling of charging piles and vehicles, thereby meeting the heat dissipation and cooling requirements of high-power charging piles and vehicles, while extending the service life of vehicle batteries and significantly improving the safety and stability of vehicles and charging piles.

[0069] According to the control method of the vehicle and charging pile synchronous cooling system in this application embodiment, it is determined whether the vehicle and charging pile generate a cooling signal. If the vehicle and charging pile generate a cooling signal, the charging pile liquid cooling system is activated based on the cooling signal. This allows the coolant in the liquid cooling tank to flow sequentially into the first liquid cooling pipe, the second liquid cooling pipe, and the third liquid cooling pipe, using liquid circulation to cool the vehicle and charging pile. This solves the problem of reduced heat dissipation efficiency due to independent heat dissipation of the vehicle or charging pile, which in turn affects the safety and stability of the vehicle and charging pile. By collecting the temperature of each connection point of the vehicle charging system, the charging pile liquid cooling system is activated when the temperature exceeds a set value. Liquid enters the liquid cooling pipes of the charging pile and the vehicle from the liquid cooling tank, achieving synchronous cooling of the vehicle and charging pile through liquid circulation, thereby improving the heat dissipation efficiency and safety of the vehicle and charging pile.

[0070] Next, the control device for the vehicle and charging pile synchronous cooling system according to the embodiments of this application is described with reference to the accompanying drawings.

[0071] Figure 3 This is a block diagram of the control device for the vehicle and charging pile synchronous cooling system according to an embodiment of this application.

[0072] like Figure 3 As shown, the vehicle and charging pile synchronous cooling system includes a temperature acquisition component, a charging gun, a charging pile liquid cooling system, and a vehicle liquid cooling system. The temperature acquisition component is installed in the vehicle's charging system. One end of the charging system is connected to the charging gun, and the other end is connected to the battery pack. The charging pile liquid cooling system includes a liquid cooling box and a first liquid cooling pipe. The liquid cooling box contains coolant. One end of the first liquid cooling pipe is connected to the liquid cooling box, and the other end is connected to a second liquid cooling pipe inside the charging gun. The vehicle liquid cooling system consists of a charging harness with a third liquid cooling pipe. One end of the third liquid cooling pipe is connected to the second liquid cooling pipe, and the other end is connected to the charging system. The control device 10 of the vehicle and charging pile synchronous cooling system includes a judgment module 100 and a control module 200.

[0073] Among them, the judgment module 100 is used to determine whether the vehicle and the charging pile generate a cooling signal;

[0074] The control module 200 is used to control the liquid cooling system of the charging pile to start based on the cooling signal generated by the vehicle and the charging pile, so that the coolant in the liquid cooling tank flows into the first liquid cooling pipe, the second liquid cooling pipe and the third liquid cooling pipe in sequence, so as to cool the vehicle and the charging pile by means of liquid circulation.

[0075] According to one embodiment of this application, the determination module 100 includes:

[0076] The first acquisition unit is used to acquire the first temperature data of the charging gun and the charging system and the second temperature data of the charging system and the battery pack, and to receive the third temperature data of the charging pile.

[0077] The first judgment unit is used to determine whether the first temperature data is greater than the first preset temperature threshold, or whether the second temperature data is greater than the first preset temperature threshold, or whether the third temperature data is greater than the first preset temperature threshold.

[0078] The generation unit is used to generate a cooling signal if the first temperature data is greater than the first preset temperature threshold, or the second temperature data is greater than the first preset temperature threshold, or the third temperature data is greater than the first preset temperature threshold.

[0079] According to one embodiment of this application, after controlling the cooling of the vehicle and charging pile using a liquid circulation method, the control module 200 includes:

[0080] The second acquisition unit is used to acquire the fourth temperature data of the charging gun and the charging system and the fifth temperature data of the charging system and the battery pack, and to receive the sixth temperature data of the charging pile.

[0081] The second judgment unit is used to determine whether the fourth temperature data is less than or equal to the second preset temperature threshold, or whether the fifth temperature data is less than or equal to the second preset temperature threshold, or whether the sixth temperature data is less than or equal to the second preset temperature threshold.

[0082] The control unit is used to shut down the liquid cooling system of the charging pile if the fourth temperature data is less than or equal to the second preset temperature threshold, or the fifth temperature data is less than or equal to the second preset temperature threshold, or the sixth temperature data is less than or equal to the second preset temperature threshold.

[0083] According to one embodiment of this application, after acquiring fourth temperature data of the charging gun and the charging system, fifth temperature data of the charging system and the battery pack, and receiving sixth temperature data of the charging pile, the second acquisition unit further includes:

[0084] The determination subunit is used to determine that the liquid cooling system of the charging pile is in a fault state if the fourth temperature data is greater than the first preset temperature threshold, or the fifth temperature data is greater than the first preset temperature threshold, or the sixth temperature data is greater than the first preset temperature threshold.

[0085] According to one embodiment of this application, after determining that the charging pile liquid cooling system is in a fault state, the determination subunit further includes:

[0086] A generation sub-component is used to generate acoustic alarm signals and / or optical alarm signals for the liquid cooling system of the charging pile based on the fault status.

[0087] The alarm sub-component is used to perform acoustic alarms on the charging pile liquid cooling system based on the acoustic alarm signal of the charging pile liquid cooling system and / or to perform optical alarms on the charging pile liquid cooling system based on the optical alarm signal of the charging pile liquid cooling system.

[0088] According to the control device of the vehicle and charging pile synchronous cooling system in this application embodiment, it determines whether the vehicle and charging pile generate a cooling signal. If the vehicle and charging pile generate a cooling signal, it controls the charging pile liquid cooling system to start based on the cooling signal, so that the coolant in the liquid cooling tank flows sequentially into the first liquid cooling pipe, the second liquid cooling pipe, and the third liquid cooling pipe, using liquid circulation to cool the vehicle and charging pile. This solves the problem of reduced heat dissipation efficiency due to independent heat dissipation of the vehicle or charging pile, which in turn affects the safety and stability of the vehicle and charging pile. By collecting the temperature of each connection point of the vehicle charging system, the device controls the charging pile liquid cooling system to start when the temperature exceeds a set value. Liquid enters the liquid cooling pipes of the charging pile and the vehicle from the liquid cooling tank, achieving synchronous cooling of the vehicle and charging pile through liquid circulation, thereby improving the heat dissipation efficiency and safety of the vehicle and charging pile.
