[0043] The technical field of electric vehicle charging piles widely covers multiple disciplines such as electrical engineering, automation control, thermal management, and Internet of Things communication. With the rapid growth of the global electric vehicle market, the demand for charging piles has increased sharply, and technological innovation has become a key factor driving the development of this field. The design of charging piles not only needs to meet the basic charging function, but also needs to consider various requirements such as user-friendliness, intelligent management, energy efficiency, and compatibility with the vehicle battery management system (BMS).

[0044] In a traditional charging pile, after being subjected to external vibrations or after long-term use, the internal power module 3 may overheat or even be damaged due to poor contact, posing a safety hazard and having low safety.

[0045] To solve the above problems, the present invention provides a horizontal charging cabinet 100, which includes: a housing 1 having a first compartment 11 and at least one second compartment 12 arranged at intervals and in the same plane, and connection holes provided at each intersection of the housing 1 corresponding to the first compartment 11 and the second compartment 12; a control module 2 disposed in the first compartment 11 for controlling the charging process; at least one power module 3, with the power modules 3 being arranged in the second compartments 12 in a one-to-one correspondence, and the power modules 3 being electrically connected to the control module 2 through the connection holes; and each of the second compartments 12 communicating with the first compartment 11.

[0046] Reference Figures 1 to 3 , in the figure, the left and right parts are the second compartments 12, and the middle part is the first compartment 11. Each compartment can be opened, and after opening the upper cover of each compartment, the corresponding module can be installed and fixed. Since the power module 3 has a low frequency of opening the cover, after the power module 3 is installed in the corresponding position, there is no need to open the cover multiple times, while the control module 2 has high operability and requires frequent operations on the control module 2, such as switching, etc. Therefore, the upper cover of the first compartment 11 is connected to the first compartment 11 in a switchable manner, which can facilitate device management and device maintenance. The first compartment 11 in this embodiment is provided with an anti-theft lock 5 to avoid unnecessary losses when the device is unattended.

[0047] It can be understood that the control module 2 is arranged in the first compartment 11, so that the control center is far from the direct power conversion area, which can better protect the electronic control components from the influence of heat sources and physical interference. The control module 2 is responsible for coordinating the entire charging process, including but not limited to formulating charging strategies, communicating with the vehicle BMS, controlling the user interface, etc.

[0048] In addition, each power module 3 corresponds to a second compartment 12, enabling each module to work independently, greatly improving the maintainability of the system. The power modules 3 are installed in the second compartments 12 one by one, which can more effectively isolate the generated heat, avoid the overheating risk caused by heat accumulation. At the same time, when maintenance is required for the power module 3, it will not affect the normal operation of other modules, and each power module 3 can also be operated independently, making the management of the power module 3 more convenient. In this way, the management ability of the power module 3, especially the thermal management ability, is increased, and the safety of the entire charging cabinet is improved.

[0049] Optionally, by designing good heat dissipation channels between compartments or an independent cooling system (such as liquid cooling or air cooling), targeted heat dissipation can be carried out for high-heat-generating modules to prevent heat from affecting each other, thereby improving the thermal stability of the entire system and enhancing the safety of this charging cabinet.

[0050] It should be noted that the number of power modules 3 is set according to requirements. Each second compartment 12 can selectively install a power module 3, or the number of second compartments 12 can be set according to the number of power modules 3 to be installed. This can expand the applicability of this charging cabinet, and the power of a single module is 30 - 40 kw.

[0051] Connection parts are provided on both sides of this horizontal charging cabinet 100, and positioning holes 13 are provided on the connection parts. This horizontal charging cabinet 100 can be fixed in a certain place through fixing parts such as screws. Sufficient air inlet and outlet space must be ensured on the front and back of this horizontal charging cabinet 100 during the installation process to avoid excessive temperature inside the cabinet body. In this way, each compartment has an independent heat dissipation structure, greatly increasing the heat dissipation performance of this horizontal charging cabinet 100.

[0052] Furthermore, each of the second compartments 12 communicates with the first compartment 11. The power module 3 needs to receive instructions from the control module 2 to start or stop charging and adjust the output power, etc. Therefore, the connection holes between the second compartment 12 and the first compartment 11 are used to achieve the electrical connection between the two. These connection holes allow wires or cables to pass through to establish an electrical connection between the two compartments.

[0053] Therefore, the technical solution of the present invention adopts a horizontal charging cabinet 100, which includes a shell and multiple compartments arranged on the same plane, namely a first compartment 11 and multiple second compartments 12, and each power module 3 is correspondingly placed in a second compartment 12. The overall layout is horizontal, enabling each power module 3 to operate independently without being affected by other power modules 3, facilitating management work, especially thermal management work, while reducing the influence between power modules, and ultimately enhancing the safety of the charging pile and the charging cabinet.

[0054] Optionally, a nameplate 4 is provided on the shell 11, and this nameplate 4 is used to mark the voltage, charging pile model, input and output parameters, etc.

[0055] In this embodiment, a fixing port is further provided on the shell 1 corresponding to the position of the second compartment 12, and one side of the power module 3 is fixed to the fixing port.

[0056] Determine the exact installation position of the power module 3 in the second bin 12. There is a fixing port on one side of this installation position, and the fixing port is used to fix one side of the power module 3. After placing the power module 3 into the second bin 12, insert it into the corresponding fixing port to complete physical fixation. Through physical fixation, even when the charging pile is subjected to external vibration, impact, or minor displacement during long-term use, the power module 3 can remain stable without displacement, reducing the failure rate caused by poor contact and looseness.

[0057] The fixing port can adopt a buckle or other objects with a fixing function. After the power module 3 is inserted into the fixing port, the above-mentioned objects are used to further limit the power module 3.

[0058] In addition, when it is necessary to replace or repair the power module 3, the fixed structural design makes the operation simpler and faster. Technicians only need to loosen the fixing parts to easily remove the module without a complex disassembly process, reducing the maintenance cost. At the same time, as mentioned above, the number of power modules 3 can be increased or decreased as needed, and this fixing port makes it more convenient to replace the power module 3.

[0059] In this embodiment, a lifting platform is provided at the position corresponding to the installation of the power module 3 in the housing. After the power module 3 is fixed to the fixing port, raise the lifting platform to abut against the power module 3; a buffer part is provided on the side of the lifting platform close to the power module 3, and the buffer part is used to slow down the collision of the power module 3.

[0060] In the housing of the charging pile, a lifting platform is provided near the installation position of the power module 3, which allows height adjustment of the power module during installation. When the power module 3 is correctly installed in place through the fixing port, the operator can activate the lifting platform control mechanism to control the lifting platform to move upward, so that the platform rises and closely adheres to the bottom of the power module 3. This process ensures the stable fixation of the power module in the housing, and even when the device is subjected to external vibration or impact, it can maintain good position stability and reduce the risk of displacement.

[0061] The buffer part provided on the lifting platform can absorb and disperse these forces when the charging pile is subjected to external impact or minor displacement caused by internal physical changes, effectively reducing the direct impact on the power module 3 and avoiding mechanical damage caused by vibration or collision, such as solder joint detachment, component cracks, etc., thereby extending the service life of the power module 3 and the overall charging pile.

[0062] In addition, during an earthquake or transportation, the charging pile may experience relatively strong vibrations. The buffer part can act as a shock-absorbing element to reduce the energy of vibrations transmitted to the power module 3, protecting sensitive electronic and electrical components from damage and ensuring the stability and reliability of the charging pile in a harsh environment.

[0063] It should be noted that, in combination with the fixed port and the buffer part described above, the fixed port provides rigid support to ensure the stable installation of the power module 3 inside the charging pile, prevent displacement under normal use or slight external force, and ensure the stability of electrical connection and the continuity of module operation. The buffer part absorbs and disperses external forces such as impacts and severe vibrations through elastic materials or structural designs, reducing the stress directly transmitted to the power module 3. The two together enhance the mechanical stability and impact resistance of the charging pile.

[0064] In this embodiment, referring to Figure 1 , at the position of the housing 1 corresponding to the second compartment 12, there is an air vent 121, and the air vent 121 is provided on the side surface of the housing 1. The air vent 121 includes an air inlet and an air outlet, both of which are arranged on the side surface of the power module 3 (the second compartment 12). Since the power module 3 generates a large amount of heat during operation, effective heat dissipation is the key to ensuring its stable operation and extending its lifespan. By providing the air vent 121 on the side surface of the power module 3 compartment, it can directly guide the external cold air to flow through the power module 3, help carry away the heat, and then discharge the hot air through the air outlet, forming an effective natural convection or auxiliary fan forced convection heat dissipation mechanism.

[0065] In this embodiment, referring to Figures 1 to 3 , the air vent 121 is provided with a pollution prevention part 1211. The pollution prevention part 1211 refers to a filtering or protective structure installed at the air vent 121. Its main function is to prevent external pollutants such as dust, impurities, fallen leaves, and insects from entering the interior of the charging pile. If these pollutants enter directly without being intercepted, they may block the heat dissipation channels, reduce the heat dissipation efficiency, and even cause damage to the internal precision electronic components.

[0066] The air vent 121 can be set in a louver shape. The louvers are special designed ventilation port fittings that can prevent moisture from directly penetrating into the equipment interior while allowing air to flow through. These louvers are usually designed with inclined blades or tiny gaps that can use surface tension and angles to block raindrops from dripping in while maintaining sufficient air circulation. Therefore, this design can avoid the situation where the components are burned out due to abnormal heat dissipation when placed on the ground floor.

[0067] The present invention also proposes a charging pile, including: the horizontal charging cabinet 100 as described above; a monitoring module, electrically connected to the control module 2 and each power module 3, for monitoring the charging process and generating corresponding control instructions according to the monitoring results; sending the control instructions to the control module 2, and the control module 2 executes corresponding charging strategies according to the control instructions.

[0068] Since the charging pile includes a horizontal charging cabinet 100, the specific structure of the horizontal charging cabinet 100 refers to the above-mentioned embodiments. Since this charging pile adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.

[0069] The monitoring module continuously monitors key parameters such as current, voltage, and temperature throughout the charging process to ensure the safe and stable power transmission during charging. Through real-time monitoring, the monitoring module can quickly identify abnormal situations, such as overheating, current overload, voltage abnormality, etc., which may be precursors to fires or equipment damage. Once an abnormality is detected, the monitoring module immediately generates a control instruction. The control module 2 receives the instruction from the monitoring module and adjusts the charging strategy accordingly, such as dynamically adjusting the charging power or cutting off the power supply when necessary, effectively avoiding safety hazards such as overheating, overvoltage, and overcurrent, and protecting the vehicle battery and the charging pile itself from damage.

[0070] The cooperation mode between the monitoring module and the control module 2 is as follows: The monitoring module is responsible for collecting on-site data in real time, which includes but is not limited to current, voltage, temperature, equipment status (such as charging status, fault signal), etc. It continuously monitors these parameters through a sensor network and performs preliminary processing to determine whether they are within the normal operating range. The collected data is sent to the processor or controller inside the monitoring module for analysis and comparison. If any abnormal situation is detected (such as abnormal increase in current, temperature exceeding the preset threshold), the monitoring module will generate corresponding control instructions or alarm signals according to the preset logic or algorithm. When the monitoring module identifies a situation that requires intervention, it will generate specific control instructions, which may include reducing the charging power, starting the cooling system, completely stopping the charging, or sending an alarm message to the operator. Then, these instructions are sent to the control module 2 through a communication interface (such as RS-485, CAN bus, Ethernet, etc.). After receiving the instruction from the monitoring module, the control module 2 performs corresponding actions according to the instruction content. This involves adjusting the states of hardware components such as relays and contactors to change the actual operating state of the system. For example, the control module 2 may close the power circuit to stop charging the electric vehicle or adjust the power management strategy to meet the current safety requirements.

[0071] It should be noted that the monitoring module in this embodiment can cooperate with the first storage bin 11 and the second storage bin 12 to independently monitor each storage bin, so as to reduce potential safety hazards and improve safety. The cooperation methods can be as follows: First, the monitoring module can integrate bin perception technologies, such as RFID, barcode scanning, or wireless sensor networks, to track the storage status, location changes, and inventory levels of items in the bin in real time. This integration can immediately detect the occupancy of the bin, prevent incorrect storage or overweight storage, thereby reducing potential safety hazards; Second, the monitoring module should not only monitor the bin status, but also monitor environmental factors such as temperature, humidity, and gas concentration to ensure that the items in the bin are in a suitable storage environment and prevent safety accidents or damages caused by environmental problems.

[0072] Therefore, the monitoring module in this embodiment realizes the comprehensive intelligent monitoring of the charging pile and its bin environment through highly integrated monitoring and management capabilities, thereby improving the safety of this charging pile.

[0073] In this embodiment, the control module 2 further includes at least one rectification module, and the rectification module is used to control the output voltage value of the charging pile and control the switching between direct current and alternating current; the rectification module is provided with an overvoltage protection function, and when the output voltage exceeds the preset voltage value, the output stops.

[0074] The installation method of the rectification module is as follows: Confirm that the system is powered off to ensure safety during the installation process. When installing the module, use the binary DIP switch to set a unique address for the rectification module. Follow the order from the high bit to the low bit (i.e., from 1 to 6, where 6 is the lowest bit), and set the DIP switch according to needs. For example, if the address is to be set to 000101 (i.e., 5), then turn the fifth switch to the ON position and keep the rest OFF. After ensuring that the DIP setting is correct, carefully align the installation direction of the module, note that the DIP switch faces upward, and then smoothly push the module into the designated slot of the charging pile. Finally, firmly fix the rectification module in the charging pile by tightening the fixing screws located on the module panel.

[0075] The built-in overvoltage protection mechanism of the rectification module can respond quickly when the output voltage rises abnormally, automatically cut off the output, prevent high voltage from damaging the electric vehicle battery, and avoid serious safety accidents such as battery thermal runaway and fire caused by overvoltage, ensuring the electrical safety of the charging process.

[0076] It should be noted that the rectification module is equipped with a short - circuit protection function. When the system detects a short - circuit situation, the rectification module can immediately activate the protection mechanism, interrupt the current output, prevent the large current caused by the short - circuit from damaging the internal components of the charging pile or causing a fire, and ensure the safety of the equipment and personnel. If the fan in the cooling system fails, the rectification module can respond in a timely manner and take measures, such as reducing the charging power or stopping the charging, to prevent the equipment from overheating, extend the service life of the equipment, and reduce the safety hazards caused by poor heat dissipation.

[0077] In addition, the rectification module is also equipped with a fan - failure protection function. If the fan in the cooling system fails, the rectification module can respond in a timely manner and take measures, such as reducing the charging power or stopping the charging, to prevent the equipment from overheating, extend the service life of the equipment, and reduce the safety hazards caused by poor heat dissipation.

[0078] In this embodiment, the monitoring module includes: a rectification monitoring module. The monitoring module monitors the working state of the rectification module, generates corresponding control instructions according to the working state of the rectification module, and sends the control instructions to the rectification module through the CAN interface; wherein, the monitoring module monitors the value of the output voltage of the rectification module, determines whether the value exceeds the preset voltage value, and generates corresponding control instructions. The rectification module reads the control instructions to control the value of the output voltage so that the value is within the preset voltage value.

[0079] The rectification monitoring module in the monitoring module continuously collects the operation data of the rectification module, especially the actual value of the output voltage. Based on the collected data, the monitoring module will analyze in real - time whether the output voltage of the rectification module exceeds the preset safety or operating voltage threshold. Once it is detected that the voltage value deviates from the preset range, the monitoring module will immediately generate corresponding control instructions according to the preset logic or algorithm. These instructions are aimed at correcting the deviation, such as reducing or cutting off the output voltage, to prevent over - voltage from damaging the electric vehicle battery or the charging system. Through the CAN interface, the monitoring module sends these control instructions to the rectification module. After receiving the instructions, the rectification module immediately adjusts its working state to ensure that the output voltage returns to the safe range.

[0080] Therefore, the cooperation between the rectification monitoring module and the rectification module, with real - time monitoring and a rapid response mechanism, significantly enhances the safety of the charging system and effectively prevents safety hazards such as battery damage and fire risks caused by abnormal voltage.

[0081] In this embodiment, the charging pile further includes: a charging gun; an auxiliary power - supply module. The auxiliary charging module is connected to the auxiliary power - supply interface of the new - energy vehicle through the charging gun. The auxiliary power - supply module is used to supply power to the low - voltage system of the new - energy vehicle and to supply power to the charging pile.

[0082] Through the auxiliary power supply module, the charging pile can directly supply power to the low-voltage system of new energy vehicles. Even when the main battery of the vehicle runs out of power or is in a low-power state, the basic electronic systems of the vehicle (such as lights, instrument panels, infotainment systems, etc.) can still operate. This design increases the flexibility of the charging scenario, allowing vehicle owners to charge safely and conveniently even in low-power situations.

[0083] At the same time, the auxiliary power supply module can independently supply power to the battery management system (BMS) of new energy vehicles, ensuring that the BMS can continuously monitor the battery status during charging, including key indicators such as temperature and voltage, and take timely measures to prevent dangerous situations such as overcharging and overheating, thus ensuring the safety of the charging process.

[0084] In this embodiment, the monitoring module includes: a system status monitoring module, which is used to monitor the working status of the charging system, generate corresponding control instructions according to the working status of the charging system, and send the control instructions to the rectifier module through the CAN interface; wherein, the working status of the charging system includes: the working status of the charging gun, the working status of the auxiliary power supply module, the working status of the electronic lock, and the working environment temperature of the charging pile.

[0085] The system status monitoring module is installed and integrated into the control system of the charging pile to ensure that it can communicate effectively with key components such as the charging gun, auxiliary power supply module, electronic lock, and environmental temperature sensor. Through software configuration, monitoring parameters, thresholds, and alarm rules are set, such as setting the detection frequency of the charging gun connection status, the normal range of the output voltage of the auxiliary power supply module, the response time of the electronic lock, and the suitable temperature range of the working environment. The monitoring module continuously collects the working status information of each part of the charging system, such as obtaining whether the charging gun is correctly connected, whether the auxiliary power supply module is supplying power normally, whether the electronic lock is locked, and the real-time temperature of the environment around the charging pile through sensors. The system status monitoring module interacts with the control module 2 to address potential safety hazards that may arise in different scenarios, thereby enhancing the safety of this charging pile.

[0086] In this embodiment, the system status monitoring module further includes a temperature monitoring module for monitoring the working temperature, and the temperature monitoring module has multiple different preset temperature values; the working temperature includes the working temperature of the charging gun, and / or the working temperature of the power module, and / or the battery temperature of the new energy vehicle; when the working temperature reaches each preset temperature value, the temperature monitoring module generates a corresponding reminder signal.

[0087] The preset temperature values with gradients generate corresponding reminder signals with gradients, enhancing the security of the system. The system status monitoring module integrates a temperature monitoring sub-module, which is responsible for continuously monitoring the temperatures of several key parts closely related to the charging process to ensure the safety of the charging operation and the stability of the equipment. These monitored temperature points include but are not limited to: the operating temperature of the charging gun, the operating temperature of the power module, and the battery temperature of the new energy vehicle, etc.

[0088] In this embodiment, the temperature monitoring module has three preset temperature values, which are 80 degrees, 90 degrees, and 98 degrees respectively: When any one of the operating temperatures of the charging gun, the operating temperature of the power module, and the battery temperature of the new energy vehicle reaches 80 degrees, or when any two of them reach 80 degrees simultaneously, or when all three reach 80 degrees simultaneously, the system generates a first reminder signal. This usually means that the temperature is starting to approach the warning level and attention is needed but it does not yet constitute an emergency. The response measures may be to record a log or issue a warning to the operator. If the temperature continues to rise and reaches 90 degrees, the system will generate a second reminder signal. This represents that the temperature has reached a relatively serious level and cooling measures may need to be taken, such as adjusting the charging power or temporarily interrupting the charging to prevent further temperature rise. The most serious situation is when the temperature reaches 98 degrees, at which time the temperature monitoring module will issue a third reminder signal. This signal usually means that immediate action must be taken, such as immediately stopping the charging, and may trigger a higher-level safety response, such as automatically cutting off the power or notifying the fire control system to intervene to prevent fires or other serious accidents.

[0089] Through such a gradient alarm mechanism, the system can take corresponding levels of response measures according to the severity of the temperature change, effectively avoiding safety accidents caused by abnormal temperatures. At the same time, it also provides a basis for the linkage with the lifting board or the third-party fire safety control platform to ensure that problems can be discovered and properly handled in a timely manner.

[0090] In this embodiment, the monitoring module includes: a cloud platform monitoring module, which receives the real-time operation data sent by the charging pile through the Internet, and the user controls the working state of the charging pile according to the real-time operation data.

[0091] In this embodiment, the real-time operation data includes: charging status, working parameters of the power module 3, and working status of the rectifier module.

[0092] The cloud platform monitoring module realizes remote intelligent management of the charging pile by receiving in real time the operation data uploaded by the charging pile (including charging status, working parameters of power module 3, and working status of the rectifier module). The cloud platform monitoring module allows users to conveniently master the working conditions of the charging pile at any time and place through a mobile application or other means, and remotely control the charging process according to actual needs, greatly improving the user experience and flexibility of use. At the same time, when the charging status of the charging pile, power module 3, or rectifier module is abnormal, the cloud platform can immediately identify it and send an alarm to the user or the operation and maintenance team through the mobile APP, enabling the problem to be quickly responded to and processed, effectively preventing small faults from evolving into major accidents.

[0093] Secondly, the cloud platform can analyze based on a large amount of collected data, timely discover and warn of potential faults, optimize the charging efficiency, ensure charging safety, and at the same time provide a data-driven basis for maintenance decisions for operators, reducing the operation cost and improving the service reliability. In addition, this remote monitoring ability also promotes the efficient allocation and utilization of resources, such as dynamically adjusting the charging power to balance the grid load, contributing to achieving a wider range of energy management and sustainable development goals.

[0094] In this embodiment, this charging pile adopts a three-phase five-wire system input. After being protected by a molded case circuit breaker (QFA1), it enters the charging rectifier module and the auxiliary power supply module. The auxiliary power supply module is responsible for providing auxiliary voltage (A+, A-) to the electric vehicle. The class C lightning arrester is connected in parallel at the input end of the charging rectifier module to provide AC lightning protection with a rated discharge current of 20KA. The charging rectifier module converts three-phase alternating current into high-voltage direct current, which is connected to the DC distribution unit through a copper busbar. According to the capacity requirements of the charger, the number of charging rectifier modules can be freely selected. The DC distribution unit connects the output high-voltage direct current to the electric vehicle charging interface through a DC charging gun, thereby charging the electric vehicle. The DC charger consists of a monitoring system and up to 2 charging rectifier modules, with a maximum output power of 60KW and an adjustable output voltage of 200 to 1000Vdc.

[0095] In this embodiment, as Figure 4 shown, a movable operation panel is also provided. Through this control panel, charging piles on different floors can be controlled simultaneously at a certain location, solving the problem of centralized operation in many occasions where the charging piles cannot be operated. The control panels of some exemplary charging piles are integrated on the pile body, and the operator needs to directly perform all settings and monitoring next to the charging pile. The movable operation panel breaks this limitation, enabling an operator to move freely within a certain range and simultaneously monitor and control multiple charging piles, greatly improving the flexibility and convenience of operation, especially in large parking lots or charging stations, saving the time and physical effort of the operator to travel back and forth between different charging piles.

[0096] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
