Abstract
Description
Technical Field
[0001] This application relates to the field of charging piles, and in particular to a 240kW European standard dual-gun DC charging pile with multi-dimensional protection functions. Background Technology
[0002] Traditional vertical DC charging piles primarily have detection functions for charging power, safety, communication, user identification, remote monitoring, and management. However, they lack corresponding detection and protection functions for their external environment. This can lead to a series of problems, such as: continuous operation in high-temperature environments will affect the lifespan of the charging pile; in flood-prone areas, failure to cut off power in time during floods can cause irreversible damage to the charging pile; after long periods of inactivity in low-temperature environments, restarting may cause some components to malfunction, resulting in charging failure; under force majeure events such as earthquakes, ground subsidence, or ground cracking, the charging pile may tip over, and if it is charging at the time, it is prone to leakage and other accidents, leading to significant safety hazards. Utility Model Content
[0003] To address the issue that vertical DC charging piles struggle to cope with special environmental conditions, this application provides a 240kW European standard dual-gun DC charging pile with multi-dimensional protection functions.
[0004] This application provides a 240kW European standard dual-gun DC charging pile with multi-dimensional protection functions, which adopts the following technical solution:
[0005] A 240kW European standard dual-gun DC charging pile with multi-dimensional protection functions includes a pile body for placing and installing electrical equipment. The pile body is equipped with a main control module, a liquid level module and an execution unit. The liquid level module is used to sense whether the liquid level in the pile body has reached a height threshold. If the height threshold is reached, the liquid level module outputs a flood threshold to the main control module. After receiving the flood threshold, the main control module disconnects the circuit in the pile body through the execution unit.
[0006] By adopting the above technical solution, the circuit can be automatically disconnected in the event of a flood, thus providing protection and improving safety.
[0007] Optionally, a radar module is also provided inside the pile body, and a display module and a transparent plate are provided on the pile body. The display module is used to display the working status of the electrical equipment inside the pile body to the user for viewing. The radar module performs radar detection through the transparent plate and outputs the radar signal to the main control module. The main control module controls the display module to turn on and off according to the radar signal.
[0008] By adopting the above technical solution, the display module lights up when someone approaches, and turns off again after a period of time when no one operates it. The power consumption of the radar sensor is significantly lower than that of the display module, which can reduce unnecessary power consumption of the charging pile in the long run.
[0009] Optionally, a smoke detection module is also provided inside the pile body. The smoke detection module is used to detect the smoke concentration inside the pile body, obtain a smoke signal and output it to the main control module. The main control module determines whether there is a fire based on the smoke signal. If there is a fire, the execution unit disconnects the circuit inside the pile body.
[0010] By adopting the above technical solution, the circuit can be automatically disconnected in the event of a fire, thus providing protection and improving safety.
[0011] Optionally, a temperature module is also provided inside the pile body. The temperature module is used to detect the temperature inside the pile body, obtain a temperature signal and output it to the main control module. The main control module determines whether the temperature is too high based on the temperature signal. If the temperature is too high, the execution unit disconnects the circuit inside the pile body.
[0012] By adopting the above technical solution, the circuit can be automatically disconnected when the temperature is too high, such as in the event of an overload, thus providing protection and improving safety.
[0013] Optionally, the detection end of the temperature module is installed inside the air inlet and air outlet of the pile body.
[0014] By adopting the above technical solution, the temperature of the air inlet and outlet determines the heat dissipation efficiency of the charging pile, thus enabling more accurate detection of heat dissipation efficiency.
[0015] Optionally, the detection end of the temperature module is also installed on the main control module.
[0016] By adopting the above technical solution, the temperature of the main control module determines the normal temperature inside the charging pile, enabling more accurate detection of the operating temperature of electrical equipment.
[0017] Optionally, a heating module is also provided inside the pile body. When the main control module determines that the temperature is too low based on the temperature signal, it controls the heating module to heat the electrical equipment inside the pile body.
[0018] By adopting the above technical solution, a suitable operating temperature is provided for the electrical equipment in the charging pile, enabling the charging pile to charge normally and operate within a better temperature range, thereby improving work efficiency.
[0019] Optionally, the pile body is also provided with a tilting module, which is used to detect the tilt of the pile body, obtain a tilting signal and output it to the main control module. The main control module determines whether the pile body is tilted based on the tilting signal. If it is determined to be tilted, the circuit in the pile body is disconnected through the execution unit.
[0020] By adopting the above technical solution, the circuit can be automatically disconnected when the charging pile tilts, thus providing protection and improving safety.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. It can automatically disconnect the circuit when the charging pile experiences overheating, overload, flooding, or tipping over, thus providing protection and improving safety.
[0023] 2. Long-term use can reduce unnecessary power consumption of charging stations. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0033] This application discloses a 240kW European standard dual-gun DC charging pile with multi-dimensional protection functions. (Refer to...) Figure 1 and Figure 2 and Figure 3 The 240kW European standard dual-gun DC charging pile with multi-dimensional protection functions includes a pile body 1 for placing and installing electrical equipment. The pile body 1 houses a main control module 11, a liquid level module 2, and an execution unit 12. A 380V three-phase AC power supply is input to a molded case circuit breaker via a three-phase five-wire connection. An AC contactor is connected to the rear end of the molded case circuit breaker. The execution unit 12 is either a molded case circuit breaker or an AC contactor, directly controlling the on / off state of the three-phase AC power input. The liquid level module 2 uses a reed switch and a float with magnets on both sides. With gravity pointing downwards, the float is positioned at the lower end of the pile body 1. The liquid level affects the height of the float, thus changing the on / off state of the reed switch via the magnets. When the liquid level in the pile body 1 reaches a height threshold, the float reaches the designated height. Under the influence of the float magnets, the reed switch conducts and outputs the flood threshold to the main control module 11. Upon receiving the flood threshold, the main control module 11 disconnects the three-phase AC power input to the pile body 1 via the execution unit 12.
[0034] Reference Figure 1 and Figure 3 The main control module 11 includes a processor and a circuit board used in conjunction with the processor. The processor may include a central processing unit such as a CPU or MPU or a host system built around a CPU or MPU, including hardware or software.
[0035] Reference Figure 1 and Figure 3 and Figure 4 A radar module 3 is also installed inside the pile body 1. A display module 31 and a transparent plate 32 are installed on the pile body 1. In this embodiment, the transparent plate 32 is made of acrylic sheet. Both the display module 31 and the transparent plate 32 are installed through the cabinet door of the pile body 1. That is, the transparent plate 32 is embedded through the cabinet door of the pile body 1. The display module 31 can be a touch screen. The display part of the display module 31 is installed on the side wall of the transparent plate 32 facing the outside of the pile body 1, such as the screen part, while the data calculation part of the display module 31 is installed on the side wall of the transparent plate 32 facing the inside of the pile body 1, such as the circuit board. The display module 31 is used to display the working status of the electrical equipment inside the pile body 1 to the user for viewing. The radar module 3 is installed on the side wall of the transparent plate 32 facing the inside of the pile body 1, that is, inside the pile body 1. It performs radar detection through the transparent plate 32 and outputs the radar signal to the main control module 11. The main control module 11 controls the display module 31 to turn on and off according to the radar signal. The radar module 3 can be a model with a power consumption of 0.24W, and the display module 31 can be a model with a power consumption of 2.64W.
[0036] Reference Figure 3 and Figure 4 A smoke detection module 4 is installed on the top wall inside the pile body 1. The smoke detection module 4 can be a smoke sensor. The smoke detection module 4 is used to detect the smoke concentration inside the pile body 1, obtain the smoke signal and output it to the main control module 11. The main control module 11 determines whether there is a fire based on the smoke signal. For example, if the smoke signal is greater than the smoke threshold, it can be determined that there is a fire. If there is a fire, the three-phase AC power input of the pile body 1 is disconnected through the execution unit 12.
[0037] Reference Figure 1 and Figure 3 and Figure 4 A temperature module 5 is also installed inside the pile body 1. The temperature module 5 can use a temperature sensor PT1000 to obtain a temperature signal and output it to the main control module 11. The main control module 11 determines whether the temperature is too high based on the temperature signal. For example, if the temperature signal exceeds the temperature threshold, it can be determined that the temperature is too high. The temperature threshold can be set according to the performance or working range of the electrical equipment. If the temperature is too high, the three-phase AC power input of the pile body 1 is disconnected through the execution unit 12.
[0038] Reference Figure 1 and Figure 4 and Figure 5 The number of temperature sensors PT1000 is at least three. These three PT1000 temperature sensors are respectively located at the air inlet of pile body 1, the air outlet of pile body 1, and the main control module 11, to more comprehensively detect the temperature inside pile body 1. Figure 4 To highlight the air intake, attached Figure 5 To highlight the air vent, attached Figure 1 To highlight the location of the main control module 11, in this embodiment, the temperature sensor PT1000 detects the temperature of the fixing screw of the main control module 11 closest to the center of the pile body 1.
[0039] Reference Figure 2 and Figure 3 A heating module 51 is also installed inside the pile body 1. The heating module 51 mainly consists of a fan and a heating resistor. The heating module 51 can be installed at the bottom of the pile body 1. When the main control module 11 determines that the temperature is too low based on the temperature signal, it controls the heating module 51 to heat the electrical equipment inside the pile body 1. The heating module 51 is mainly oriented towards the main control module 11 to heat the main control module 11.
[0040] Reference Figure 6 and Figure 7A tilting module 6 is also installed on the inner wall of the pile body 1. The tilting module 6 is installed at the upper part of the pile body 1. The tilting module 6 is used to detect the tilt of the pile body 1, obtain the tilting signal and output it to the main control module 11. The main control module 11 determines whether the pile body 1 has tilted based on the tilting signal. For example, if the tilting signal exceeds the tilting threshold, it is tilted. If it is determined to be tilted, the circuit inside the pile body 1 is disconnected through the execution unit 12.
[0041] The implementation principle of a 240kW European standard dual-gun DC charging pile with multi-dimensional protection function in this application embodiment is as follows: in the event of overheating, flooding, or overturning, the main input is automatically disconnected to protect the electrical equipment inside the pile body 1, while also protecting the surrounding equipment and personnel.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
