Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to an adaptive current home AC charging pile. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. With the explosive growth of new energy vehicles, public charging piles can no longer meet people's needs, and more and more people are starting to install home charging piles. AC charging piles refer to charging piles that convert AC power into DC power to charge electric vehicles.

[0003] However, existing adaptive current home AC charging piles have the following shortcomings: However, in existing technologies, traditional charging piles typically only monitor voltage to determine whether derating is necessary. This ignores the actual "health status" and carrying capacity of the power grid (affected by transformer capacity, line aging, connection impedance, and other loads). Voltage drops may already be a delayed manifestation of overload. At the same time, there is a lack of efficient energy conversion mechanisms. For example, ordinary DC / DC converters have significant losses during voltage conversion, resulting in an overall charging and discharging efficiency of only about 85% to 90%. During charging, the charging strategy cannot be flexibly adjusted according to the voltage status, which can easily lead to overcharging and undercharging, thus limiting the overall performance of the charging pile.

[0004] Therefore, we propose an adaptive current home AC charging station to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive current home AC charging pile. By embedding a signal disturbance measurement unit, the complex online power grid impedance measurement technology is miniaturized, reduced in cost, and integrated into the home charging pile. This allows for the perception of the power grid's carrying capacity from the source, achieving true "adaptiveness," far exceeding simple voltage monitoring. Furthermore, through a micro supercapacitor module, it flexibly switches between boost and buck modes based on the power grid status, achieving efficient power conversion and solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive current household AC charging pile, including a heat dissipation mechanism, a cabinet door mechanism on one side of the outer wall of the heat dissipation mechanism, a wire harness mechanism on the back of the heat dissipation mechanism, and a control module, a charging module and a micro supercapacitor module respectively disposed inside the heat dissipation mechanism. The control module includes: The main control unit, Bluetooth unit, 4G communication unit, power management unit, and temperature detection unit are used to control the entire charging pile. The charging module includes: The signal disturbance measurement unit, EMI filtering unit, power correction unit, AC / DC power supply unit, and output switching unit are used to charge the vehicle. The miniature supercapacitor module includes: The supercapacitor array, bidirectional conversion unit, battery management unit, and equalization unit are used to solve the problems of charging and discharging efficiency and speed.

[0007] Preferably, the heat dissipation mechanism includes a heat dissipation shell, with a set of heat dissipation vents on both sides of the outer wall of the heat dissipation shell, a protective shell welded inside the heat dissipation shell, a phase change plate disposed inside the protective shell, heat dissipation fins attached to the back of the phase change plate, a bracket mounted on one side of the outer wall of the protective shell, and a set of fans mounted on one side of the outer wall of the bracket.

[0008] Preferably, three sets of magnets are installed on both sides of the inner wall of the protective shell, and three support plates are embedded in the inner wall of the protective shell. The three support plates are all in contact with one side of the outer wall of the phase change plate. A set of grooves is opened on both sides of the outer wall of the three support plates, and each set of grooves is fitted with each set of magnets. The control module, the charging module and the micro supercapacitor module are respectively installed at the bottom of the three support plates.

[0009] Preferably, a sealing plate is installed on one side of the outer wall of the protective shell, a sealing strip is embedded on the top of the protective shell, a back plate is installed on the back of the heat dissipation shell, and an emergency stop switch is provided on the top of the heat dissipation shell.

[0010] Preferably, the cabinet door mechanism includes a cabinet door, with a display module and an NFC sensing module respectively installed on one side of the outer wall of the cabinet door, and the cabinet door is connected to one side of the outer wall of the heat dissipation shell via a hinge.

[0011] Preferably, a metal plate is installed on one side of the inner wall of the cabinet door, and a set of wiring terminals and a surge protector are installed on one side of the outer wall of the metal plate.

[0012] Preferably, a charging gun port is embedded on one side of the outer wall of the cabinet door, and two wiring ports are provided at the bottom of the cabinet door.

[0013] Preferably, the wire harnessing mechanism includes a fixed plate, an L-shaped plate welded to one side of the outer wall of the fixed plate, a motor mounted on one side of the outer wall of the L-shaped plate, a wire harnessing roller mounted on one side of the inner wall of the L-shaped plate, the output end of the motor being fixedly connected to one end of the outer wall of the wire harnessing roller, and a set of fixing frames welded to one side of the outer wall of the fixed plate.

[0014] Preferably, the fixing plate is installed on one side of the outer wall of the back plate by bolts.

[0015] Preferably, the micro supercapacitor module is electrically connected to the AC / DC power supply unit of the charging module through a bidirectional conversion unit, and both the micro supercapacitor module and the charging module are electrically connected to the control module.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a built-in signal disturbance measurement module enables precise grid state perception and adaptive control. Before charging begins, and during charging intervals and low-power charging periods, this module injects non-invasive test signals of specific frequency and amplitude into the grid, such as specific harmonics or pseudo-random sequences. Simultaneously, a high-precision ADC samples the grid's response to the injected signals, acquiring data such as voltage changes and phase shifts. Based on this data, the charging pile uses an online system identification algorithm to calculate the equivalent grid impedance of the charging point in real time. Combined with the real-time voltage, the control module accurately calculates the maximum safe current carrying capacity of the current grid branch. This value is dynamically updated according to the grid state and serves as the charging pile's adaptive current. The charging pile automatically reduces the maximum allowable charging current when the grid impedance increases, indicating a weak grid. Conversely, it moderately increases the current within a safe range when the grid impedance decreases, thus establishing an active and reliable protection mechanism based on grid condition awareness. In addition, when a short-term grid voltage drop is detected, the micro supercapacitor module in the charging pile can respond quickly and use the bidirectional conversion unit to inject active power into the local load (including vehicles that are being charged) with the energy stored in the supercapacitor, supporting the voltage of critical loads and improving power reliability. Furthermore, the charging pile can also actively perform power quality management work such as harmonic compensation and reactive power compensation during the idle time after the vehicle is fully charged or before the scheduled charging begins, improving the overall performance of the charging pile.

[0017] 2. In this invention, a multi-level safety protection system is constructed through a systematic heat dissipation and protection design. At the core functional module level, phase change plates are integrated at the bottom of the control module, charging module, and micro supercapacitor module. These phase change plates utilize high latent heat storage materials, which can absorb and store heat during equipment operation, effectively suppressing sudden local temperature rises. Heat dissipation fins are tightly attached to the back of the phase change plate, forming an active heat dissipation structure in conjunction with an intelligent speed-regulating fan. When the temperature detection unit detects that the internal temperature rise has reached a threshold, the fan automatically increases its speed to accelerate air convection and quickly dissipate heat, achieving efficient heat dissipation. This also enhances the protection... In terms of structural design, each functional module is encapsulated in a high-strength protective shell, which, together with the sealing plate, forms an IP65-level protection, effectively resisting the intrusion of dust and water splashes. At the same time, an independent air duct design is adopted, with airflow entering and exiting through a dedicated channel to prevent external dust from contacting electronic components, thus physically eliminating the risk of short circuits caused by dust accumulation. In addition, the back of the heat dissipation shell uses a metal mesh grid to construct a Faraday cage structure, which can effectively shield external electromagnetic interference and ensure the stable operation of core functions such as signal transmission of the control module, power conversion of the charging module, and charging and discharging control of the micro supercapacitor module, thereby comprehensively improving the safety and reliability of the charging pile.

[0018] 3. In this invention, to balance structural stability and ease of maintenance, the control module, charging module, and micro supercapacitor module are all equipped with a magnetic quick-release structure. Each module has an independent support plate at its bottom, with magnetically conductive material embedded in the plate. This plate forms a stable adsorption connection with a powerful permanent magnet pre-installed on the inner wall of the protective shell. While ensuring the module is securely installed, it effectively isolates the impact of mechanical vibration on electronic components. When maintenance is required, technicians can easily separate the module from the protective shell for quick disassembly, significantly improving maintenance efficiency. In addition, the cable management mechanism adopts an adaptive tightening design. The cable management roller is driven by a motor to rotate, automatically adjusting the binding force according to the specifications of the charging cable. This effectively fixes the cable, preventing the interface from loosening due to dragging, and also facilitates quick plugging and unplugging operations for users, balancing practicality and safety.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, such as Figures 1-3 As shown: An adaptive current household AC charging pile includes: a heat dissipation mechanism 100, a cabinet door mechanism 200 on one side of the outer wall of the heat dissipation mechanism 100, a wire harness mechanism 300 on the back of the heat dissipation mechanism 100, and a control module 400, a charging module 500, and a micro supercapacitor module 600 respectively disposed inside the heat dissipation mechanism 100. The heat dissipation mechanism 100 effectively reduces the operating temperature of the internal components, avoids performance degradation or failure due to overheating, and extends the service life of the charging pile. The cabinet door mechanism 200 facilitates daily inspection and maintenance, improves operational convenience, and the wire harness mechanism 300 organizes the wiring, prevents wire tangling and wear from causing short circuits and other safety hazards, and enhances the overall safety and reliability of the charging pile. like Figure 7As shown: The control module 400 includes a main control unit 401, a Bluetooth unit 402, a 4G communication unit 403, a power management unit 404, and a temperature detection unit 405, which are used to control the entire charging pile. In the control module 400, the main control unit 401 coordinates the overall operation of each module. The Bluetooth unit 402 and the 4G communication unit 403 enable local and remote interaction. Users can remotely control charging and check the status through a mobile APP. The power management unit 404 optimizes power distribution and reduces energy consumption. The temperature detection unit 405 monitors the temperature in real time and, together with the heat dissipation mechanism, ensures a stable internal environment. like Figure 8 As shown: The charging module 500 includes a signal disturbance measurement unit 501, an EMI filtering unit 502, a power correction unit 503, an AC / DC power supply unit 504, and an output switching unit 505, which is used to charge the vehicle. Within the charging module 500, the signal disturbance measurement unit 501 monitors the signal quality in real time, and the EMI filtering unit 502 reduces electromagnetic interference to ensure a stable charging signal. The power correction unit 503 improves the power factor and reduces grid losses. The AC / DC power supply unit 504 efficiently converts electrical energy. The output switching unit 505 flexibly adjusts the output mode according to the vehicle's needs to achieve stable and efficient charging. like Figure 9 As shown, the micro supercapacitor module 600 includes a supercapacitor array 601, a bidirectional conversion unit 602, a battery management unit 603, and an balancing unit 604. It is used to solve the problems of charging and discharging efficiency and speed. The micro supercapacitor module 600 provides energy storage support with high energy density and long cycle life through the supercapacitor array 601. The bidirectional conversion unit 602 realizes efficient bidirectional energy conversion with multiple working modes. The battery management unit 603 and the balancing unit 604 work together to accurately monitor and balance the performance of individual cells, solving the problems of low charging and discharging efficiency, slow speed, and large differences between individual cells in traditional energy storage. It can quickly respond in scenarios such as fast charging of vehicles and improve the overall performance of charging piles.

[0023] In this embodiment, the charging pile achieves intelligent adaptive charging through multi-module collaboration. The control module 400 uses an STM32H743VI main control unit 401 as its core, and achieves bidirectional data interaction between the local mobile APP and the remote server through a Bluetooth unit 402 and a 4G communication unit 403. The Bluetooth unit 402 uses a CC2640R2F chip supporting the BLE 5.0 protocol, with a transmission distance of over 10 meters, enabling close-range configuration of the charging pile. The 4G communication unit 403 uses an EC200S module, supporting LTE... The T.1 network, with a download speed of 10Mbps, meets the requirements for remote monitoring and OTA upgrades. The TPS65987A power management unit 404 adopts a multi-output design (3.3V / 5V / 12V) with a conversion efficiency of over 92%. Through dynamic load management, it reduces standby power consumption to below 0.5W. The TMP117 temperature detection unit 405 deploys 6 temperature measurement points in key modules with a measurement accuracy of ±0.1℃. When the temperature of the main control unit 401 exceeds 70℃, it automatically triggers the cooling fan 107 to increase its speed to 5000rpm. When the charging module 500 is working, the signal disturbance measurement unit 501 first injects a specific harmonic signal (amplitude of 0.3% to 1% of the rated voltage) from 200Hz to 2kHz into the power grid. After sampling by a 24-bit high-precision ADC, the main control unit 401 uses a recursive least squares method (forgetting factor 0.995) to calculate the power grid impedance in real time, updating the data every 200ms. The upper limit of the current is adjusted in 0.5A steps to ensure a stable AC input for the on-board charger. The EMI filtering unit 502 adopts a π-type filter structure with a common-mode choke inductance of 20mH, achieving a 65dB suppression ratio for 1MHz interference signals. This ensures that the charging process complies with the CISPR14-1 electromagnetic compatibility standard, avoiding electromagnetic interference to the power grid and surrounding equipment. The power correction unit 503 uses average current mode control with a switching frequency of 100kHz to improve the power factor to above 0.992. This system improves the efficiency of charging piles in obtaining power from the grid by 15%, reduces reactive power loss, and increases grid utilization. The AC / DC power supply unit 504 adopts an LLC resonant topology to provide stable DC power to the micro supercapacitor module 600 inside the charging pile. The efficiency reaches 96.8% when outputting at 12V / 24V. By reducing diode voltage drop loss through synchronous rectification technology, the output voltage ripple is controlled within ±50mV, ensuring the stable operation of the micro supercapacitor module 600 and providing reliable power support for emergency operation and data storage of the charging pile. The output switching unit 505 communicates with the vehicle BMS based on the CAN bus and adjusts the output AC voltage (220V / 380V) and current limit according to the BMS command. It supports the coordination with the on-board charger to complete the CC / CV charging mode switching. The solid-state relay switching time is <5ms and can withstand 600V voltage surge, ensuring the safety and reliability of the charging process. The graphene-based supercapacitor array 601 of the micro supercapacitor module 600, when the grid voltage drops by more than 5%, the synchronous rectification Buck-Boost circuit of the bidirectional conversion unit 602 switches from Buck mode to Boost mode within 20ms, injecting active power into the load with an efficiency of 97% and a continuous support time of ≥30s. The LTC6813-1 chip of the battery management unit 603 collects the individual cell voltage data every 10ms. When the individual cell voltage difference is detected to exceed 50mV, the balancing unit 604 starts active balancing, realizing energy transfer through the energy storage inductor, with a balancing efficiency of over 90%, ensuring that the difference in lifespan of each cell in the array is <5%. During charging intervals or scheduled periods, the system analyzes the grid current waveform through a harmonic detection algorithm, calculates the content of the 3rd to 13th harmonics, and then controls the IGBT module to generate a reverse-phase compensation current, which can reduce the grid THD from 12% to 4.8%, while dynamically adjusting the reactive power output to keep the power factor above 0.99, comprehensively improving grid adaptability and charging efficiency.

[0024] Example 2, as Figures 4-6 As shown, the heat dissipation mechanism 100 includes a heat dissipation shell 101. A set of heat dissipation vents 102 are provided on both sides of the outer wall of the heat dissipation shell 101. A protective shell 103 is welded inside the heat dissipation shell 101. A phase change plate 104 is provided inside the protective shell 103. Heat dissipation fins 105 are attached to the back of the phase change plate 104. A bracket 106 is installed on one side of the outer wall of the protective shell 103. A set of fans 107 is installed on one side of the outer wall of the bracket 106. Three sets of magnets 110 are installed on both sides of the inner wall of the protective shell 103. Three support plates 108 are embedded in the inner wall of the protective shell 103, and the three support plates 108 are all attached to one side of the outer wall of the phase change plate 104. A set of grooves 109 are opened on both sides of the outer wall of the three support plates 108, and each set of grooves 109 is respectively fitted into each set of magnets 110. The control module 400, the charging module 500 and the micro supercapacitor module 600 are respectively installed at the bottom of the three support plates 108. A sealing plate 111 is installed on one side of the outer wall of the protective shell 103, a sealing strip 112 is embedded on the top of the protective shell 103, a back plate 113 is installed on the back of the heat dissipation shell 101, and an emergency stop switch 114 is provided on the top of the heat dissipation shell 101.

[0025] In this embodiment, the heat dissipation mechanism 100 provides efficient thermal management and safety protection for the charging pile through a multi-layer composite heat dissipation design and structural reinforcement. The heat dissipation vents 102 on both sides of the heat dissipation shell 101 are arranged obliquely in a biomimetic fish gill style, combined with an aerodynamic airflow design, which can improve airflow efficiency by 25% under natural convection conditions. After the fan 107 is started, it can form directional forced convection to quickly dissipate internal heat. The internally welded protective shell 103 adopts a high-strength aluminum alloy one-piece molding process with a yield strength of over 200MPa. It not only builds a physical protective barrier for the core components, but also acts as a rigid support for the heat dissipation structure. The phase change plate 104 adopts RT44HC phase change material, which has high latent heat storage capacity. The heat sink can quickly absorb and store heat during equipment startup or high-load operation, slowing down the rate of internal temperature rise and controlling component temperature fluctuations within ±3℃. The heat sink fins 105, which are closely attached to the back, are processed by microchannel milling to form a honeycomb heat dissipation structure, which greatly increases the heat dissipation surface area. Combined with the airflow generated by the fan 107, the heat dissipation efficiency can be greatly improved. In addition, the heat sink 101 and the heat dissipation port 102 form a Faraday cage structure, which can effectively shield external electromagnetic interference and ensure the stable operation of core functions such as signal transmission of the control module 400, power conversion of the charging module 500, and charging and discharging control of the micro supercapacitor module 600, thereby comprehensively improving the safety and reliability of the charging pile. The magnet 110 on the inner wall of the protective shell 103 and the groove 109 of the support plate 108 form a magnetic quick-release structure. Combined with the fixing effect of the sealing plate 111, it ensures that the control module 400, the charging module 500 and the micro supercapacitor module 600 are securely installed. At the same time, they can be separated by applying vertical force during disassembly. Compared with traditional screw fixing, the maintenance efficiency is greatly improved. The sealing plate 111 and the top sealing strip 112 form an IP65-level protective barrier, effectively preventing dust and water stains from entering. The back plate 113 on the back of the heat dissipation shell 101 and the top emergency stop switch 114 further enhance the safety performance. The back plate 113 can prevent foreign objects from entering the equipment from the rear, and the emergency stop switch 114 can achieve power-off protection within 0.5 seconds in an emergency, comprehensively improving the safety, stability and maintainability of the charging pile operation.

[0026] Example 3, according to Figures 1-3 As shown, the cabinet door mechanism 200 includes a cabinet door 201. A display module 202 and an NFC sensing module 203 are respectively installed on one side of the outer wall of the cabinet door 201. The cabinet door 201 is connected to one side of the outer wall of the heat dissipation shell 101 via a hinge. A metal plate 204 is installed on one side of the inner wall of the cabinet door 201. A set of wiring terminals 205 and a surge protector 206 are respectively installed on one side of the outer wall of the metal plate 204. A charging gun port 207 is embedded on one side of the outer wall of the cabinet door 201. Two wiring ports 208 are provided at the bottom of the cabinet door 201. The wire harnessing mechanism 300 includes a fixed plate 301, an L-shaped plate 302 welded to one side of the outer wall of the fixed plate 301, a motor 303 mounted on one side of the outer wall of the L-shaped plate 302, a wire harnessing roller 304 mounted on one side of the inner wall of the L-shaped plate 302, the output end of the motor 303 being fixedly connected to one end of the outer wall of the wire harnessing roller 304, and a set of fixing brackets 305 welded to one side of the outer wall of the fixed plate 301.

[0027] In this embodiment, the cabinet door mechanism 200 and the cable management mechanism 300, through human-computer interaction optimization and intelligent cable management, construct a convenient operation interface and safe wiring system for the charging pile. The display module 202 integrated on the outer wall of the cabinet door 201 displays charging parameters and power grid status in real time. The NFC sensing module 203 supports the ISO14443A protocol and has a card reading distance of 0-5cm, enabling users to start charging by swiping their cards without contact. A set of terminal blocks 205 uses UK10N type terminal blocks, which can carry 60A current. Together with the surge protector 206 (Type 2 surge protector, response time <25ns, current capacity 10kA), it forms a three-level surge protection system. The charging gun port 207 has a built-in electronic locking mechanism. The two bottom terminal blocks 208 use M20 waterproof glands, which are compatible with 6-16mm² cables, ensuring waterproof sealing when installed outdoors. The fixing plate 301 of the cable harness mechanism 300 is fixed to the back of the heat sink 101 by four M6 stainless steel bolts. The motor 303 drives the cable harness roller 304 to automatically rewind the cable, avoiding cable dragging and wear, while keeping the site clean and improving the operation convenience and environmental adaptability of the charging pile.
