Description

Technical Field

[0001] This invention relates to the field of liquid cooling technology, and in particular to a liquid-cooled charging pile replenishment device and method, electronic equipment, and computer-readable storage medium. Background Technology

[0002] Compared to traditional air-cooled chargers, fully liquid-cooled chargers offer advantages such as lower noise, lower failure rate, longer lifespan, higher efficiency, and better customer experience. Fully liquid-cooled chargers rely on coolant for heat dissipation. Insufficient coolant can severely impact charger cooling, leading to overheating, reduced output power, and in severe cases, overheating protection shutdown, even affecting module performance and reliability. Currently, coolant replenishment is mostly done manually on-site when coolant is insufficient. However, this method is costly and carries the risk of adding too much or too little coolant, affecting stable power output. Summary of the Invention

[0003] This invention aims to at least partially address one of the technical problems in the prior art. To this end, this invention proposes a liquid-cooled recharger replenishment device and method, electronic equipment, and storage medium, which can improve the operational stability of the liquid-cooled recharger replenishment device.

[0004] In a first aspect, embodiments of the present invention provide a liquid-cooled charging pile replenishment device, comprising: The coolant reservoir is used to supply coolant. The liquid cooling system water tank is equipped with a first liquid level reed switch, which is used to detect the real-time liquid level of the liquid cooling system water tank. A water pump is connected to both the replenishment water tank and the liquid cooling system water tank. The control unit is connected to the water pump and the first liquid level reed switch, respectively, and is used to control the water pump to replenish liquid according to the detection status of the first liquid level reed switch.

[0005] Optionally, in one embodiment of the present invention, a second liquid level reed switch is provided in the replenishment tank, the second liquid level reed switch being used to detect the real-time liquid level of the replenishment tank; the second liquid level reed switch is connected to the control unit.

[0006] Optionally, in one embodiment of the present invention, the control unit is provided with a first detection interface and a second detection interface, the first detection interface being connected to the first liquid level reed switch, and the second detection interface being connected to the second liquid level reed switch.

[0007] Optionally, in one embodiment of the present invention, the water pump and the control unit communicate via RS-485.

[0008] In a second aspect, embodiments of the present invention provide a liquid replenishment method for the liquid-cooled charging pile replenishment device as described in the first aspect, comprising: When the control unit determines that the real-time liquid level of the liquid cooling system tank is at the first preset liquid level based on the detection of the first liquid level reed switch, the control unit starts the water pump to replenish the coolant provided by the replenishment tank into the liquid cooling system tank.

[0009] Optionally, in one embodiment of the present invention, after starting the water pump based on the control unit, the method further includes: Once the real-time liquid level change of the liquid cooling system tank is detected to be at the second preset liquid level, the water pump is shut down based on the control unit.

[0010] Thirdly, embodiments of the present invention provide an electronic device, comprising: At least one processor; At least one memory for storing at least one program; When at least one of the programs is executed by at least one of the processors, the liquid replenishment method of the liquid-cooled charge stack replenishment device as described in the second aspect is implemented.

[0011] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a processor-executable program, which, when executed by a processor, is used to implement the liquid replenishment method of the liquid-cooled charge stack replenishment device as described in the second aspect.

[0012] The liquid-cooled recharger replenishment device, method, electronic equipment, and storage medium proposed in this invention provide coolant to the liquid-cooled system tank by setting up a replenishment tank. Since the liquid-cooled system tank is equipped with a first level reed switch for detecting the real-time liquid level, and the control unit is connected to both the water pump and the first level reed switch, when the control unit determines that the real-time liquid level of the liquid-cooled system tank is at a first preset level based on the detection data from the first level reed switch, the control unit can start the water pump to replenish the coolant provided by the replenishment tank into the liquid-cooled system tank. This achieves timely and effective intelligent replenishment. Compared with existing technologies, this not only improves the operational stability of the liquid-cooled recharger replenishment device but also reduces the workload of maintenance personnel performing on-site replenishment, thus lowering maintenance costs.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0015] It should be noted that although functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0016] like Figure 1 As shown, the liquid-cooled charging pile replenishment device may include, but is not limited to: The coolant tank 100 is used to supply coolant; The liquid cooling system water tank 200 is equipped with a first liquid level reed switch 210, which is used to detect the real-time liquid level of the liquid cooling system water tank 200. Water pump 300 is connected to liquid replenishment tank 100 and liquid cooling system tank 200 respectively; The control unit 400 is connected to the water pump 300 and the first liquid level reed switch 210 respectively, and is used to control the water pump 300 to replenish liquid according to the detection status of the first liquid level reed switch 210.

[0017] The coolant stored in the replenishing tank 100 can be pre-configured. When replenishment is needed, the water pump 300 connected to the replenishing tank 100 can draw the coolant from the replenishing tank 100 into the liquid cooling system tank 200. It should be noted that the specifications and parameters of the replenishing tank 100 and the liquid cooling system tank 200 can be set according to the actual application scenario, and there are no restrictions here.

[0018] In one embodiment, the control unit 400 may be, but is not limited to, a PLC control cabinet or an integrated industrial control module. Its specific architecture can be set according to the actual application scenario. It is only necessary to ensure that it is connected to the water pump 300 and the first liquid level reed switch 210 respectively, so as to effectively obtain the real-time detection status of the first liquid level reed switch 210.

[0019] In one embodiment, the first liquid level reed switch 210 may, but is not limited to, achieve liquid level monitoring through a linkage structure between the reed switch and the magnetic float. The float triggers the magnetic reed switch to operate as the liquid level changes, thereby outputting a liquid level signal to the control unit 400. In this embodiment, the first liquid level reed switch 210 supports an operating environment from -10℃ to 100℃ and has a maximum pressure resistance of 1.5MPa.

[0020] In one embodiment, the replenishment tank 100 may be equipped with, but is not limited to, a second liquid level reed switch 110. The second liquid level reed switch 110 is used to detect the real-time liquid level of the replenishment tank 100. The second liquid level reed switch 110 is connected to the control unit 400. That is, by setting the second liquid level reed switch 110 to further monitor the liquid level in the replenishment tank 100, when the liquid level is detected to be too low, the control unit 400 can issue a prompt signal, such as uploading an alarm signal to the backend cloud platform, to remind the cloud platform's maintenance personnel to replenish the liquid in the replenishment tank 100.

[0021] In one embodiment, such as Figure 2 As shown, the control unit 400 is internally provided with a first detection interface 420 and a second detection interface 410. The first detection interface 420 is connected to the first liquid level reed switch 210 through the liquid cooling system water tank 200, and the second detection interface 410 is connected to the second liquid level reed switch 110 through the replenishment water tank 100. By setting the first detection interface 420 and the second detection interface 410, it is ensured that the control unit 400 can be electrically connected to the first liquid level reed switch 210 and the second liquid level reed switch 110, thereby realizing stable signal interaction between the control unit 400 and each liquid level reed switch.

[0022] In one embodiment, the water pump 300 and the control unit 400 can communicate via, but are not limited to, RS-485. Specifically, the RS-485 bus standard specifies the electrical characteristics of the bus interface, namely, the definition of two logic states: a positive level between +2V and +6V represents one logic state; a negative level between -2V and -6V represents the other logic state; the digital signal uses differential transmission, which can effectively reduce the interference of noise signals.

[0023] The liquid-cooled recharger replenishment device and application scenarios described in the embodiments of the present invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those skilled in the art will know that with the evolution of liquid-cooled recharger replenishment devices and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0024] It will be understood by those skilled in the art that Figure 1 or Figure 2The liquid-cooled charging pile replenishment device shown does not constitute a limitation on the embodiments of the present invention. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0025] based on Figure 1 or Figure 2 The structure of the liquid-cooled charge stack replenishment device is shown in the figure, and various embodiments of the replenishment method of the present invention are proposed.

[0026] Figure 3 This is a flowchart of a liquid replenishment method for a liquid-cooled charging pile replenishment device according to an embodiment of the present invention. The replenishment method may include, but is not limited to, step S1.

[0027] Step S1: When the control unit determines that the real-time liquid level of the liquid cooling system water tank is at the first preset liquid level based on the detection of the first liquid level reed switch, the control unit starts the water pump to replenish the coolant provided by the replenishment water tank into the liquid cooling system water tank.

[0028] In this step, a replenishment tank is set up to supply coolant to the liquid cooling system tank. Since the liquid cooling system tank is equipped with a first level reed switch to detect the real-time liquid level, and the control unit is connected to both the water pump and the first level reed switch, when the control unit determines that the real-time liquid level of the liquid cooling system tank is at a first preset level based on the reed switch's detection, the control unit can start the water pump to replenish the coolant supplied by the replenishment tank into the liquid cooling system tank. This achieves timely and effective intelligent replenishment, which, compared to existing technologies, not only improves liquid cooling charging... The stable operation of the liquid cooling system replenishment device can also reduce the workload of maintenance personnel in on-site liquid replenishment, thereby reducing maintenance costs. It can be seen that the real-time liquid level of the liquid cooling system tank in the liquid-cooled charging pile replenishment device can be detected. When insufficient coolant is detected, the water pump is started through the control unit to automatically replenish the liquid cooling system tank, ensuring that there is enough coolant in the tank and sufficient coolant flow during operation. This is conducive to the normal heat dissipation of the liquid cooling system tank and the realization of stable power output. Especially for unmanned stations, automatic liquid replenishment can be carried out at the first time when the liquid is insufficient, without the need for maintenance personnel to handle on-site, thus reducing the operating costs of the charging station.

[0029] like Figure 4 As shown in one embodiment of the present invention, step S1 may be followed by, but is not limited to, step S2.

[0030] Step S2: Once the real-time liquid level change of the liquid cooling system water tank is detected to the second preset liquid level, the water pump is shut down based on the control unit.

[0031] In this step, once the real-time liquid level change of the liquid cooling system tank is detected to be at the second preset liquid level, it indicates that the real-time liquid level of the liquid cooling system tank has reached the expected level, and there is no need to continue to replenish the liquid. Therefore, the water pump can be turned off based on the control unit to avoid over-replenishment, which could affect the normal operation of the liquid cooling system tank.

[0032] In one embodiment, when the liquid level in the liquid cooling system tank reaches a first preset liquid level or a second preset liquid level, the resistance of the first liquid level reed switch will change. Therefore, the control unit can determine the current liquid level status of the liquid cooling system tank by detecting the change in the resistance of the first liquid level reed switch. Similarly, the change in the resistance of the second liquid level reed switch can also characterize the current liquid level status of the replenishment tank.

[0033] In one embodiment, the actual definitions of the first preset liquid level and the second preset liquid level can be various, such as defining them according to the real-time range of liquid level values, with the first preset liquid level being between the first liquid level and the second liquid level, and the second preset liquid level being between the third liquid level and the fourth liquid level, etc. There is no limitation here.

[0034] Figure 5 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present invention. For example...
