Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and in particular, to a charging pile, an application environment control method and device. Background Art

[0002] A DC distributed charging pile is a charging device independently composed of a host and charging terminals, with a power range covering 360 - 720 kW. All charging terminals share the power of the host, and can dynamically allocate power according to the charging requirements of different vehicles, and perform unified scheduling and management to reduce the impact on the power grid. It is mainly applicable to large-scale centralized charging scenarios and ultra-fast charging demonstration scenarios, and is currently widely used in the field of new energy vehicle charging.

[0003] In the prior art, most DC distributed charging piles use AC and DC fans to achieve the internal cabinet heat dissipation of the charging pile host, thereby changing the application environment of the charging pile. As Figure 1 shown, this method controls the start and stop of the fan FJ through the heat dissipation system controller F3 to adjust the temperature inside the charging pile cabinet, but this method generally has problems such as low heat exchange efficiency, high aging rate and failure rate of components, and excessive occupation of the internal cabinet space resulting in unreasonable layout.

[0004] Moreover, there are many electrical components inside the charging pile host cabinet, and there are relatively strict requirements for the application environment such as temperature, humidity, and protection during its operation. The above application environment control method has a single function and only controls the temperature variable. Facing a complex application environment, it cannot fully meet the requirements of "reliability and stability", and it is difficult to effectively ensure the long-term safe operation of the charging pile.

[0054] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0055] With the booming development of the new energy vehicle industry, the sales volume of new energy vehicles has been increasing year by year, and more and more people choose new energy electric vehicles. However, the construction of the charging network lags far behind the plan, and the technological development of charging infrastructure cannot keep up with the rapid development pace of new energy vehicles.

[0056] The DC distributed charging pile is a charging device independently composed of a host and charging terminals, with a power range covering 360 - 720kW. All charging terminals share the power of the host, and the power can be dynamically allocated according to the charging requirements of different vehicles, with unified scheduling and unified management, reducing the impact on the power grid. It is mainly applicable to large-scale centralized charging scenarios and ultra-fast charging demonstration scenarios, and is currently widely used in the field of new energy vehicle charging.

[0057] In the prior art, most DC distributed charging piles use AC-DC fans to achieve the internal cabinet heat dissipation of the charging pile host, thereby changing the application environment of the charging pile. For example Figure 1 As shown, this method controls the start and stop of the fan FJ through the heat dissipation system controller F3 to adjust the temperature inside the charging pile cabinet. However, this method generally has problems such as low heat exchange efficiency, high aging rate and failure rate of components, and excessive occupation of cabinet space resulting in unreasonable layout.

[0058] Moreover, there are many electrical components inside the charging pile host cabinet, and there are relatively strict requirements for the operating temperature, humidity, protection and other application environments. The above application environment control method has a single function and only controls the temperature variable. Facing a complex application environment, it cannot fully meet the requirements of "reliability and stability", and it is difficult to effectively ensure the long-term safe operation of the charging pile.

[0059] In view of this, the present invention provides a charging pile. See Figure 2 As shown, it is a specific embodiment of a charging pile provided by the present invention. In this embodiment, the charging pile includes:

[0060] A controller 40 (not shown in the figure), a charging unit 60, a power distribution unit 70, and an air conditioning unit 80;

[0061] The charging unit 60 is used to convert the input alternating current into direct current and supply power to the electrical equipment;

[0062] The power distribution unit 70 is used to distribute the output power of the charging unit 60 to match the power requirements of the electrical equipment;

[0063] Wherein, the charging pile further includes an AC input unit 10, an AC input control unit 50, a lightning protection unit 20, an auxiliary power supply unit 30, and a main cabinet 90;

[0064] The AC input unit 10 is used to supply power to the air conditioning unit 80, the charging unit 60, and the power distribution unit 70;

[0065] The lightning protection unit 20 is used to provide overvoltage protection for the charging pile;

[0066] The auxiliary power supply unit 30 is used to temporarily supply power to the charging pile when the AC input unit is interrupted or unavailable;

[0067] The AC input control unit 50 is used to adjust the input voltage of the AC input unit 10 to output a stable voltage;

[0068] The AC input unit 10, the lightning protection unit 20, the auxiliary power supply unit 30, the AC input control unit 50, the charging unit 60, and the power distribution unit 70 are integrally installed in the main cabinet 90;

[0069] The output end of the air conditioning unit 80 is electrically connected to the main cabinet 90.

[0070] The controller 40 is configured to collect the environmental information inside the charging pile; the environmental information includes temperature information, humidity information, smoke information, and water immersion information; and is configured to determine the first operating parameter of the air conditioning unit according to the temperature information and / or humidity information; determine the first environmental control strategy of the charging pile according to the first operating parameter; and control the air conditioning unit 80 by using the first environmental control strategy. The controller 40 is further configured to determine the second operating parameter of the AC input unit 10 according to the smoke information and / or water immersion information; determine the second environmental control strategy of the charging pile according to the second operating parameter; and control the AC input unit 10 by using the second environmental control strategy.

[0071] The air conditioning unit 80 adopts an industrial-grade air conditioner and executes the control instructions of the controller in response to the first environmental control strategy.

[0072] Specifically, the AC input unit 10 in this embodiment is the input interface of the charging stack, which is the bridge for signals to enter the entire charging stack and is used to input electrical signals to other units. The input type can be AC input. The lightning protection unit 20 can use an AC lightning arrester to achieve the guidance, release, and isolation of lightning by utilizing physical properties such as conductivity, dischargeability, and shielding, thereby providing overvoltage protection for the charging stack and achieving the purpose of lightning protection for the entire charging stack and improving safety performance. The auxiliary power supply unit 30 serves as the secondary power supply of the entire charging stack. When the AC input unit 10 is interrupted or unavailable, the auxiliary power supply unit 30 will continue to supply power to the devices in the charging stack to ensure the smooth execution of the key operations of the charging stack. The AC input control unit 50 adjusts the input voltage of the AC input unit 10 by controlling the components (circuit breakers, contactors, relays, etc.) in the control circuit, thereby outputting a stable voltage. The output terminal then transmits the regulated voltage to the charging unit 60, the power distribution unit 70, and other circuits that need power supply. The charging unit 60 is the basic unit for realizing power conversion such as rectification, inversion, and filtering. Its main function is to convert the alternating current in the charging stack power grid into direct current that can be used to charge the battery. The power distribution unit 70 is composed of a certain number and types of power distribution sub-units (PDUs), which can ensure the safe and effective distribution of power to multiple electrical devices, while protecting the electrical devices and realizing the effective management of power usage. Thus, the purpose of distributing the output power of the charging unit 60 to match the power requirements of the electrical devices is achieved. To optimize the structural design layout and ensure the long-term safe operation of the charging stack, the AC input unit 10, the lightning protection unit 20, the auxiliary power supply unit 30, the AC input control unit 50, the charging unit 60, and the power distribution unit 70 are integrally installed in the main cabinet 90. However, various units, especially the charging unit 60 and the power distribution unit 70, will generate a large amount of heat and humidity changes during operation. These heats fill the enclosed space in the main cabinet 90 of the charging stack, and the humidity changes will also affect the stable operation of the internal components of the units. Therefore, the air conditioning unit 80 is required to adjust the temperature and humidity. The air conditioning unit 80 uses a high-power, highly integrated industrial-grade air conditioner to replace the AC and DC fans in the prior art, greatly improving the heat exchange rate between the inside of the main cabinet 90 of the charging stack and the external environment, quickly reducing the cabinet temperature below the critical temperature, and the air conditioning unit 80 can also adjust the humidity. It effectively ensures the stability of the cabinet environment and further ensures the long-term safe operation of the charging stack. The number and power of the air conditioning unit 80 can be increased or decreased according to the power of the charging stack. The chassis of the air conditioning unit 80 can be installed on the outer side of the door of the main cabinet 90, and its output terminal is connected to the main cabinet 90, which does not occupy the space inside the cabinet, can greatly improve the space utilization rate inside the main cabinet 90 of the charging stack, and thus save equipment and construction costs.In addition, the air-conditioning chassis of the air-conditioning unit 80 can be completely embedded in the rear cabinet door of the main cabinet 90, so that the entire charging pile is fully sealed, and the protection level can reach IP56, which can effectively prevent dust and the like from entering the main cabinet 90, avoiding affecting the heat dissipation, insulation and working efficiency of the copper busbars and components in the cabinet. It effectively solves problems such as high surface flashover rate of copper busbars, high aging rate of components, and high failure rate, ensuring the long-term safe operation of the charging pile. The controller 40 can collect the environmental information in the main cabinet 90 through temperature sensors, humidity sensors, smoke sensors, water immersion sensors, etc. arranged in the main cabinet 90. The environmental information includes temperature information, humidity information, smoke information and water immersion information. When the temperature and humidity in the environmental information reach the adjustment conditions, the first operating parameters of the air-conditioning unit can be determined according to the temperature information and / or humidity information, and the first environmental control strategy of the charging pile can be determined according to the first operating parameters, that is, lowering or raising the temperature and humidity. The air-conditioning unit 80 is controlled by using the first environmental control strategy to keep the application environment of the charging pile stable. The controller 40 is also used to determine the second operating parameters of the AC input unit 10 according to the smoke information and / or water immersion information, and determine the second environmental control strategy of the charging pile according to the second operating parameters, that is, shutting off the input of the AC input unit 10, and controlling the AC input unit 10 by using the second environmental control strategy to cut off the power supply of the charging pile in time in the face of special environments such as fire or flooding.

[0073] The above-mentioned constituent units of the charging pile and the controller 40 cooperate together to ensure that the charging pile can maintain a reliable and stable power output environment, and ensure the safe and long-term operation of the charging pile.

[0074] It should be noted that the specific types, quantities and combinations of the AC input unit 10, lightning protection unit 20, auxiliary power supply unit 30, controller 40 (not shown in the figure), AC input control unit 50, charging unit 60, power distribution unit 70, air-conditioning unit 80 and main cabinet 90 can be adjusted according to the actual requirements of the application scenario, and the embodiments of the present application do not limit this.

[0075] It can be seen from the above technical solutions that the beneficial effects of this embodiment are: by adopting an industrial-grade air conditioner, the high efficiency and airtight safety of the heat exchange between the charging pile and the outside world are realized, and at the same time, the humidity adjustment function is added, effectively reducing problems such as high failure rate and component aging caused by too high temperature and poor airtightness in the main cabinet of the charging pile.

[0076] The present invention also provides a method for controlling the application environment of a charging pile. Refer to Figure 3 As shown, it is a specific embodiment of a method for controlling the application environment of a charging pile provided by the present invention. In this embodiment, the method is applied to Figure 2 the charging pile described above, and the method includes:

[0077] Step 101: Collect the environmental information inside the charging pile; the environmental information includes temperature information, humidity information, smoke information, and water immersion information.

[0078] In this embodiment, due to the modular configuration of the charging pile, it has relatively high requirements for its application environment. To ensure the safe and stable operation of the charging pile, it is necessary to monitor the internal application environment of the charging pile in real time, so as to control the operation of the charging pile according to the relevant monitored information.

[0079] Specifically, relevant environmental information is collected through monitoring and measuring devices such as temperature sensors, humidity sensors, smoke sensors, and water immersion sensors arranged in the main cabinet of the charging pile. The environmental information includes temperature information collected by the temperature sensor; humidity information collected by the humidity sensor; smoke information collected by the smoke sensor; water immersion information collected by the water immersion sensor. Among them, the water immersion sensor is a sensor that detects whether there is water leakage in the measured range. Once water leakage occurs, an alarm is immediately issued to prevent water leakage from the air conditioning unit or water leakage from the main cabinet due to poor sealing, causing relevant losses and hazards. The smoke sensor includes various types and can be classified into the following categories: photoelectric smoke sensors, which use the photoelectric effect to detect the presence of smoke; ionization smoke sensors, which use the ionization effect to detect the presence of smoke; thermal smoke sensors, which use thermistors to detect temperature changes to determine whether there is smoke. This embodiment does not limit the type.

[0080] Step 102: Determine the first operating parameter of the air conditioning unit according to the temperature information and / or humidity information.

[0081] By presetting the temperature application threshold and humidity application threshold of the charging pile, determine the temperature adjustment range according to the temperature information and the temperature application threshold, determine the humidity adjustment range according to the humidity information and the humidity application threshold, and determine the first operating parameter according to the temperature adjustment range and / or humidity adjustment range. Specifically, the operating environment of the charging pile has requirements for temperature and humidity. Too high or too low temperature and humidity will affect its stable operation. Therefore, the temperature application threshold and humidity application threshold of the charging pile can be preset. The temperature application threshold and humidity application threshold can be the temperature range and humidity range required for the stable operation of the charging pile. The charging unit and power distribution unit will generate a large amount of heat during operation and fill the enclosed space inside the main cabinet of the charging pile. At the same time, external environmental changes will also affect the temperature and environment inside the main cabinet. When the current temperature and current humidity detected by the sensor exceed the temperature application threshold and humidity application threshold, the controller will receive an alarm message and determine the temperature adjustment range and humidity adjustment range in combination with the exceeded value, that is, determine whether to lower or raise the corresponding temperature and humidity. The indicators of the temperature and humidity that need to be adjusted are the first operating parameters of the air conditioning unit.

[0082] Step 103: Determine the second operating parameter of the AC input unit according to the smoke information and / or water immersion information;

[0083] Specifically, determine the air index in the charging pile according to the smoke information. When the air index reaches the preset first shutdown threshold, determine the first shutdown parameter of the AC input unit; determine the water immersion state in the charging pile according to the water immersion information, and determine the second shutdown parameter of the AC input unit according to the water immersion state. Determine the second operating parameter according to the first shutdown parameter and the second shutdown parameter. The presence of smoke in the charging pile may be due to the ignition of components caused by short circuit and overheating of the internal circuit. Therefore, being able to cut off the fire source in time is also an important indicator for the safe operation of the charging pile. In addition, due to the water-cooled design of the air-conditioning unit or the appearance of condensed water droplets due to a large temperature difference, water leakage occurs at the outlet end of the air-conditioning unit or the main cabinet leaks due to poor sealing during external rain. These water leakages will damage the components running inside the main cabinet. When water leakage occurs and may affect the safe operation of the charging pile, cutting off the power supply in time is also an important indicator for the safe operation of the charging pile. Therefore, the air index can be the smoke concentration in the charging pile, and the first shutdown threshold can be the preset smoke concentration when the charging pile is not allowed to be powered on. When the air index reaches the preset first shutdown threshold, it indicates that there may be a phenomenon of circuit ignition in the charging pile, and the first shutdown parameter of the AC input unit is determined to be 0, that is, the off state. The water immersion state can be whether there is water leakage. When it is detected that there is water leakage, the second shutdown parameter of the AC input unit is determined to be 0, that is, the off state. Combining the first shutdown parameter and the second shutdown parameter, as long as at least one of them appears, the second operating parameter of the AC input unit is 0 (off).

[0084] Step 104: Determine the environmental control strategy of the charging pile according to the first operating parameter and the second operating parameter; control the charging pile to operate according to the environmental control strategy.

[0085] As known above, the first operating parameter mainly controls the normal operating environment of the temperature and humidity of the charging pile, and the second operating parameter mainly controls the emergency operating environment of the charging pile in case of fire and water bubbles. Determine the environmental control strategy of the charging pile according to the first operating parameter and the second operating parameter. This environmental control strategy is to adjust the temperature, adjust the humidity, and turn off the AC input unit.

[0086] Specifically, when the first operating parameter is to increase the temperature, the air-conditioning unit receives the temperature increase instruction from the controller and controls the reversing valve and the auxiliary heater of the air-conditioning unit to work to achieve the purpose of increasing the temperature; when the first operating parameter is to decrease the temperature, the air-conditioning unit receives the temperature decrease instruction from the controller, and the condensation compressor of the air-conditioning unit starts to refrigerate. When the temperature drops to the temperature application threshold, the controller issues an instruction to the air-conditioning unit, and the condensation compressor of the air-conditioning unit stops working to complete the whole machine heat dissipation process.

[0087] When the first operating parameter is that humidification is required, the controller issues an instruction to the humidifier in the air-conditioning unit to achieve the purpose of humidification; when the first operating parameter is that dehumidification is required, the controller issues an instruction to the air-conditioning unit, and the compressor and solenoid valve of the air-conditioning unit work to achieve a constant-temperature dehumidification state.

[0088] When the second operating parameter is that the AC input unit needs to be turned off, there may be a fire or water bubble phenomenon in the main cabinet of the charging pile. The controller issues an instruction to the AC input unit to turn off the switch of the circuit input of the AC input unit, cut off the power in time, and prevent the loss from expanding.

[0089] Operating according to the above environmental control strategy can effectively ensure that the charging pile is in a stable operating environment with constant temperature and humidity, and when a sudden situation occurs, it can respond in time to prevent the situation from expanding.

[0090] From the above technical solutions, it can be seen that the beneficial effects of this embodiment are as follows: By controlling the charging pile to operate according to this environmental control strategy, the environment inside the main cabinet of the charging pile is kept constant. In the face of sudden situations such as fire or flooding, it can cut off the power in time for protection, and can operate safely and effectively for a long time. The application of the environmental control method is diverse, suitable for relatively important conditions with high safety requirements, and has great significance for popularization.

[0091] Figure 3 The shown is only the basic embodiment of the method of the present invention. On this basis, with certain optimization and expansion, other preferred embodiments of the method can also be obtained.

[0092] As Figure 4 shown, it is another specific embodiment of an environmental control method for a charging pile application of the present invention. This embodiment is further described on the basis of the foregoing embodiment. In this embodiment, the method includes the following steps:

[0093] Step 201: Determine the liquid source according to the waterlogging information;

[0094] As can be seen from the above embodiment, when water leakage occurs in the charging pile, it is necessary to quickly cut off the input of the AC input unit. However, if only the power is cut off and the water leakage continues to occur, it is very likely to cause the expansion of the accident. Therefore, it is also necessary to trace back the source of the water leakage and prevent the water leakage from occurring in time.

[0095] Specifically, the waterlogging sensor can detect the waterlogging information. When it is installed, there are key monitoring areas, such as near the water source: under the cooling pipe of the air-conditioning unit, around the humidifier of the air-conditioning unit, and the position where condensate is likely to drip at the top of the main cabinet; low-lying areas: the lowest point on the ground of the main cabinet; the joint area of the main cabinet, etc., to avoid monitoring blind spots. Through the monitoring of the waterlogging sensor, it is possible to determine the area where the liquid appears when water leakage occurs for the first time, thereby identifying the liquid source, that is, the location where the water leakage phenomenon occurs.

[0096] Step 202: Determine the access control status of the main cabinet and / or the valve status of the cooling pipe of the air conditioning unit according to the liquid source;

[0097] Judging from experience, the water leakage in the main cabinet of the charging pile may come from the closing condition of the cabinet door. If it is not closed tightly, water in the external environment may enter the main cabinet. It may also come from the water leakage of the cooling pipe of the air conditioning unit. Therefore, by judging the liquid source, the cause of the water leakage can be determined. For example, when it is monitored that there is water leakage in the joint area of the main cabinet, it may be because the cabinet door is not closed. When it is monitored that there are only condensed water droplets falling from the top of the main cabinet, it may be because the cooling pipe of the air conditioning unit leaks and the water vapor condenses on the top of the main cabinet. At this time, it is necessary to determine the access control status (open / closed) of the main cabinet and the valve status (open / closed) of the cooling pipe of the air conditioning unit.

[0098] Step 203: Determine the third operating parameter of the charging pile according to the access control status and / or the valve status; control the charging pile to operate according to the third operating parameter.

[0099] The third operating parameter is the closing of the main cabinet door and / or the closing of the valve of the cooling pipe of the air conditioning unit.
