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

[0050] The following describes the control method, device and electronic device of the synchronous cooling system of the vehicle and charging pile of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the heat dissipation efficiency is reduced by the independent heat dissipation of the vehicle or charging pile, thereby affecting the safety and stability of the vehicle and the charging pile, the present application provides a control method of the synchronous cooling system of the vehicle and the charging pile, in which it is judged whether the vehicle and the charging pile generate a cooling signal. If the vehicle and the charging pile generate a cooling signal, the charging pile liquid cooling system is controlled to start based on the cooling signal, so that the coolant in the liquid cooling box flows into the first liquid cooling pipe, the second liquid cooling pipe and the third liquid cooling pipe in sequence, and the vehicle and the charging pile are cooled by liquid circulation. Thus, the problem of the independent heat dissipation of the vehicle or the charging pile to reduce the heat dissipation efficiency, thereby affecting the safety and stability of the vehicle and the charging pile, is solved. By collecting the temperature of each connection point of the vehicle charging system, the charging pile liquid cooling system is controlled to start when the temperature is greater than the set value, and the liquid enters the liquid cooling pipe of the charging pile and the vehicle from the liquid cooling box 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.

[0051] Specifically, Figure 1 A flow chart of a control method for a synchronous cooling system of a vehicle and a charging pile provided in an embodiment of the present 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 arranged in the charging system of the vehicle, one end of the charging system is connected to the charging gun, and the other end of the charging system 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 includes a coolant. One end of the first liquid cooling pipe 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 in the charging gun. The vehicle liquid cooling system is composed 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 of the third liquid cooling pipe is connected to the charging system. The control method of the 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 cooling signals.

[0054] According to one embodiment of the present application, determining whether a vehicle and a charging pile generate a cooling signal includes: collecting first temperature data of a charging gun and a charging system and second temperature data of a charging system and a battery pack, and receiving third temperature data of a 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, a cooling signal is generated.

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

[0056] Specifically, in the embodiment of the present application, in order to solve the problems that the heat dissipation efficiency is reduced due to independent heat dissipation of the vehicle or the charging pile, and the synchronous cooling of the vehicle and the charging pile cannot be achieved, thereby affecting the safety and stability of the vehicle and the charging pile, the embodiment of the present application collects the temperature of each connection point of the vehicle charging system, and controls the charging pile liquid cooling system to start when the temperature is greater than the set threshold. The coolant enters the liquid cooling pipes of the charging pile and the vehicle from the liquid cooling tank 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, if Figure 2As shown, the embodiment of the present application mainly includes a temperature detection system, a charging pile liquid cooling system and a vehicle liquid cooling system, wherein the temperature detection system contains a temperature acquisition component, i.e., a temperature sensor, and the temperature acquisition component is arranged in the charging system (mainly including a charging seat and a connector) of the vehicle charging high-voltage wire harness, one end of the charging system is connected to the charging gun, and the other end of the charging system is connected to the battery pack. First, the temperature acquisition component continuously and in real time acquires the first temperature data of the connection between the charging gun and the charging seat in the charging system and the second temperature data of the connection between the connector and the battery pack in the charging system, and receives the third temperature data sent by the charging pile in real time; secondly, the above-mentioned collected and received temperature data are judged. 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, it means that the temperature of the vehicle or the charging pile is too high, which will affect the charging efficiency and the charging safety and stability of the vehicle and the charging pile. Therefore, it is necessary to cool down the vehicle and the charging pile. At this time, the temperature acquisition component is used through the VCU (Vehicle Control Unit, vehicle control unit), BMS (Battery Management System, battery management system) and each charging interface send a start signal of the liquid cooling system, that is, a cooling signal, to the charging pile to achieve cooling and heat dissipation of the vehicle and the charging pile.

[0058] In step S102, if the vehicle and the charging pile generate cooling signals, the charging pile liquid cooling system is controlled to start based on the cooling signal, so that the coolant in the liquid cooling box flows into the first liquid cooling tube, the second liquid cooling tube and the third liquid cooling tube in sequence, so as to cool the vehicle and the charging pile by liquid circulation.

[0059] Among them, 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 is filled with coolant required for cooling (including but not limited to water, ethylene glycol, silicone oil, etc.). One end of the first liquid cooling pipe (for example, 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 in 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 is composed 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 evenly wrapped with copper wire. One end of the third liquid cooling pipe (for example, 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 seat in the charging system.

[0060] Specifically, Figure 2As shown, in an embodiment of the present application, when the vehicle and the 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 based on the cooling signal, so that the coolant in the liquid cooling box flows into the first liquid cooling pipe of the charging pile liquid cooling system, and then flows into the third liquid cooling pipe of the vehicle liquid cooling system through the second liquid cooling pipe in the charging gun, and then enters the charging seat in the charging system through the third liquid cooling pipe, and then flows into the cooling water tank through the cable, and then flows through the charging system of the vehicle. The heat is taken away by the coolant through heat transfer, and then returns to the charging pile through the liquid outlet, thereby achieving cooling of the vehicle and the charging pile through liquid circulation.

[0061] According to one embodiment of the present application, after controlling the cooling of the vehicle and the charging pile by using liquid circulation, it includes: 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; judging 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; 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 controlling the liquid cooling system of the charging pile to be shut down.

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

[0063] Specifically, after the vehicle and the charging pile are cooled down by liquid circulation, the embodiment of the present application continues to collect the fourth temperature data of the connection between the charging gun and the charging seat in the charging system and the fifth temperature data of the connection between the connector and the battery pack in the charging system, and receives the sixth temperature data sent by 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, it means that the temperature of the vehicle and the 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 charging pile liquid cooling system is controlled to be shut down.

[0064] According to one embodiment of the present 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, it also 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, it is determined that the liquid cooling system of the charging pile is in a fault state.

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

[0066] Specifically, in an embodiment of the present application, after cooling the vehicle and the charging pile by liquid circulation, if the fourth temperature data collected at the connection between the charging gun and the charging seat 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 sent by the charging pile is greater than the first preset temperature threshold, then it means that the charging pile liquid cooling system has a fault, and after cooling the vehicle and the charging pile by the charging pile liquid cooling system, the fourth temperature data, the fifth temperature data and the sixth temperature data are not less than or equal to the second preset temperature threshold. Therefore, an alarm is required for this fault state.

[0067] Specifically, in an embodiment of the present application, when a fault occurs in the charging pile liquid cooling system, an acoustic alarm can be performed on the charging pile liquid cooling system based on the acoustic alarm signal of the charging pile liquid cooling system, for example, an acoustic alarm can be performed on the charging pile liquid cooling system through an acoustic alarm signal such as a buzzer or a voice broadcasting device, and / or an optical alarm can be performed on the charging pile liquid cooling system based on an optical alarm signal of the charging pile liquid cooling system, for example, an optical alarm signal such as an LED (Light-Emitting Diode) display, thereby prompting the user that the charging pile liquid cooling system is in an abnormal fault state and needs to be corrected in time to ensure the safety of the vehicle and the charging pile.

[0068] In summary, through the specific discussion of the above embodiments, the present application can achieve synchronous cooling of the charging pile and the vehicle, thereby meeting the heat dissipation and cooling needs of the high-power charging pile and the vehicle, while extending the service life of the vehicle battery and significantly improving the safety and stability of the vehicle and the charging pile.

[0069] According to the control method of the synchronous cooling system of the vehicle and the charging pile of the embodiment of the present application, it is determined whether the vehicle and the charging pile generate a cooling signal. If the vehicle and the charging pile generate a cooling signal, the charging pile liquid cooling system is controlled to start based on the cooling signal, so that the coolant in the liquid cooling box flows into the first liquid cooling tube, the second liquid cooling tube and the third liquid cooling tube in sequence, and the vehicle and the charging pile are cooled by liquid circulation. In this way, the problem of reducing the heat dissipation efficiency by independently cooling the vehicle or the charging pile, thereby affecting the safety and stability of the vehicle and the charging pile, is solved. By collecting the temperature of each connection point of the vehicle charging system, the charging pile liquid cooling system is controlled to start when the temperature is greater than the set value, and the liquid enters the liquid cooling tube of the charging pile and the vehicle from the liquid cooling box 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.

[0087] An alarm sub-component is used to acoustically alarm the charging pile liquid cooling system based on the acoustic alarm signal of the charging pile liquid cooling system and / or to optically alarm 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 synchronous cooling system of the vehicle and the charging pile of the embodiment of the present application, it is determined whether the vehicle and the charging pile generate a cooling signal. If the vehicle and the charging pile generate a cooling signal, the charging pile liquid cooling system is controlled to start based on the cooling signal, so that the coolant in the liquid cooling box flows into the first liquid cooling pipe, the second liquid cooling pipe and the third liquid cooling pipe in sequence, and the vehicle and the charging pile are cooled by liquid circulation. In this way, the problem of reducing the heat dissipation efficiency by independently cooling the vehicle or the charging pile, thereby affecting the safety and stability of the vehicle and the charging pile, is solved. By collecting the temperature of each connection point of the vehicle charging system, the charging pile liquid cooling system is controlled to start when the temperature is greater than the set value, and the liquid enters the liquid cooling pipe of the charging pile and the vehicle from the liquid cooling box 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.
