Description

Technology Field

[0001] The present invention relates to a charger for smartphones and electronic devices, and more specifically, to a multi-functional charger capable of both wired and wireless charging. Background Technology

[0003] As the use of portable electronic devices such as smartphones, tablet PCs, wireless earphones, and smartwatches is rapidly increasing in modern society, various charging devices for charging these devices are being used in daily life.

[0004] Most homes and office spaces are equipped with various types of chargers, and users often use multiple charging cables or plug multiple chargers into a power strip to charge various electronic devices simultaneously.

[0005] However, existing chargers have a structural problem in that charging cables are prone to getting twisted or tangled when multiple cables are present.

[0006] If you move the device or pull the charging cable while it is charging, the wire often twists or gets tangled with other cables, causing it to easily break or the insulation to be damaged.

[0007] This results in reduced charging efficiency or inconveniences such as poor contact during charging causing the device's terminals to shake or charging to stop.

[0008] In particular, the charger's ports (terminals) are vulnerable to repeated attachment and detachment and physical load, so problems frequently occur where the metal terminals become loose or break easily due to poor contact during use.

[0009] In addition, since chargers and cables are parts that users frequently touch with their hands, contaminants such as dust, oil, and bacteria easily accumulate from the outside.

[0010] In particular, the charging cable or the top of the charger is in prolonged contact with hands, making it prone to becoming an environment for bacterial growth, and prolonged use is highly likely to cause hygiene issues.

[0011] Nevertheless, conventional chargers do not have structures or functions that take these hygiene issues into account, making it difficult for users to maintain cleanliness.

[0012] Meanwhile, while the widespread adoption of wireless charging technologies (such as the Qi standard) offers the convenience of charging without a cable connection, a new problem arises when wireless and wired chargers are used together.

[0013] The internal coils of a wireless charger generate an electromagnetic field during operation, and this magnetic field can affect the power circuits of adjacent wired chargers, causing electromagnetic interference (EMI) or inducing phenomena such as voltage fluctuations and reduced charging speed.

[0014] In addition, wireless chargers tend to generate significant heat in the coils during charging, and if a wired charger adapter or cable is placed nearby, the accumulation of heat may shorten the lifespan of the charger or cause safety issues due to overheating.

[0015] Furthermore, when multiple chargers are connected to a power strip simultaneously, there is a risk of exceeding the rated current, heat accumulation, and power interference. In particular, when chargers are located close to each other, the heat generated by the power adapters may overlap, or the magnetic field of the wireless charger may interact with the metal parts of the wired port, potentially leading to charging instability, increased heat, and malfunction.

[0016] For these reasons, existing chargers have various limitations, such as the inconvenience of cable management, reduced port durability, hygiene issues due to bacterial contamination, and problems with electromagnetic interference and heat generation when wired and wireless chargers are used simultaneously.

[0017] Therefore, there is an increasing need for a new charging system that allows for the free adjustment of charger placement according to the user environment, enables hygiene management even during charging, and minimizes mutual interference when wired and wireless chargers are used simultaneously. The problem to be solved

[0019] Accordingly, the present invention was conceived in the aforementioned background,

[0020] The main objective is to provide a charging system with structural flexibility that allows cables to not get tangled or twisted even when charging multiple electronic devices simultaneously, the ports or terminals of the charger to not be easily damaged even with repeated use, and the placement of the charger to be freely adjusted according to the usage environment.

[0021] In addition, another objective of the present invention is to implement a charger system equipped with a hygiene management function that minimizes bacterial contamination or hygiene problems that may occur on the charger surface or charging cable area frequently touched by the user's hands even during charging, and prevents unpleasant dust, contamination, and bacterial proliferation that occur during the use of the charger.

[0022] In addition, an important technical objective of the present invention is to implement a power management and interference suppression structure that fundamentally reduces problems such as electromagnetic interference (EMI), heat accumulation, and voltage instability that may occur when wired and wireless chargers are used together in the same space, and enables each charger to maintain a stable power supply without interfering with one another.

[0023] Furthermore, another objective of the present invention is to provide an integrated charging system that maximizes user convenience and space utilization, while simultaneously ensuring power efficiency and safety, by enabling the efficient performance of wired charging, wireless charging, and hygiene management functions within a single system without requiring the user to manage multiple chargers individually or configure the charging space in a complex manner. means of solving the problem

[0025] To achieve these objectives, one embodiment of the present invention is,

[0026] A modular charging station comprising a wireless charging block module, a wired charging block module, and a disinfectant block module, wherein the wireless charging block module is configured to charge an electronic device such as a smartphone according to a wireless power transmission method, the wired charging block module is configured to provide wired charging through a cable, and the disinfectant block module is configured to disinfect the surface of the electronic device using an ultraviolet LED, wherein each block module shares a common power bus and can be freely separated and combined with one another via magnets and alignment mechanisms, and the charging mode and disinfection mode are controlled to be automatically selected according to the position and order of the combination.

[0027] At this time, the wireless charging block module (10) includes a wireless charging coil assembly based on the Qi standard, and the coil assembly includes a magnetic alignment ring magnet to automatically align with the charging coil of the electronic device, and a ferrite sheet and a conductive shielding layer are disposed on the rear surface of the coil to block electromagnetic interference between adjacent block modules.

[0028] In addition, the wired charging block module includes a smartphone stand and a cable separation space, and the cable separation space can store an extra charging cable. A cable exit light-blocking channel is formed in the part where the cable is pulled out to the outside, thereby preventing ultraviolet leakage when combined with a sterilizer block module, and controlling heat generation by gradually reducing the current when the temperature of the port is 55℃ or higher.

[0029] Additionally, the above-described sterilizer block module is formed in a rectangular structure with an open bottom, and the inner surface is provided with a reflector or PTFE liner having a reflectivity of 70% or more, and the ultraviolet LED panel includes a UV-C LED with a wavelength range of 260 nm to 280 nm, and the sterilizer control unit controls the ultraviolet LED to operate only when the block module is completely sealed using an interlock sensor, and it is preferable to stop the operation of the ultraviolet LED when no object to be sterilized is present by a foreign object detection sensor.

[0030] Meanwhile, the modular charging station described above includes a dynamic power management function in which multiple block modules share the same power bus, and power distribution is automatically adjusted according to the operating status of each module.

[0031] The above power bus is configured with a sensor network that detects the current, voltage, and temperature status of each block module in real time, and if heat generation during wireless charging exceeds a reference temperature (50℃), the UV LED output of the sterilizer block module is automatically reduced to 40% or less of the rated value, and

[0032] The disinfector control unit receives an operation signal from a wireless charging block module or a wired charging block module (20), and dynamically calculates the ultraviolet irradiation dose (Dtarget) in the range of 2 mJ / cm² to 20 mJ / cm² when charging and disinfection are performed simultaneously.

[0033] The connection between each block module ensures directionality using neodymium magnets and asymmetric mechanical keys, and

[0034] The inter-block coupling signal is processed into an integrated control signal including temperature, light, and magnetic sensing data, and immediately cuts off the UV LED if heat generation or light leakage is detected during charging.

[0035] It is also desirable that each block module be characterized by autonomously recognizing the operating mode even when separated and stacked, and being controlled to switch to one of a wireless charging mode, a wired charging mode, a disinfection mode, or a simultaneous charging and disinfection mode. Effects of the invention

[0037] According to one embodiment of the present invention,

[0038] According to the present invention, even when multiple chargers or charging cables are used simultaneously, the cables can be kept in an organized state without twisting or tangling each other, so the user can efficiently charge multiple electronic devices without complex cable management work.

[0039] Accordingly, this prevents the cable from getting tangled or twisted around other cables during charging, thereby fundamentally preventing problems such as disconnection or poor connection, and maintaining stable charging efficiency.

[0040] In addition, the present invention improves the structural durability of the charging port and terminal portion so that it is not easily damaged even by repeated attachment and detachment or external force, thereby significantly extending the lifespan of the charger.

[0041] In particular, by including a support structure for holding a smartphone, the load applied to the cable or terminal during charging is distributed, thereby effectively preventing poor contact of the port or internal disconnection.

[0042] Considering hygiene issues regarding the charger surface or cable parts that users frequently touch with their hands, the present invention can be designed to enable ultraviolet (UV) sterilization and disinfection of the smartphone surface or surrounding environment even during charging.

[0043] This inhibits the proliferation of bacteria attached to the charger and smartphone, and maintains the cleanliness of the parts that come into contact with the user's hands, thereby providing a hygienic and safe charging environment.

[0044] This improves practical user convenience by enabling hygiene management during the daily charging process without the need for separate disinfection procedures.

[0045] Furthermore, the present invention can integrate and manage power supply paths so that problems such as electromagnetic interference (EMI), heat accumulation, and power instability do not occur even when wired charging block modules and wireless charging block modules are used simultaneously.

[0046] Through a common power bus and shielding structure, each module operates independently without affecting one another, ensuring that charging efficiency remains constant and the safety of the device is secured even when wired and wireless chargers are used in parallel.

[0047] In particular, through heat management and electromagnetic shielding design, stable operation is possible even during prolonged charging, and multiple charging functions can be performed simultaneously without degradation of power efficiency.

[0048] The charging station according to the present invention adopts a modular structure, allowing the user to selectively combine one or more of wired charging, wireless charging, and disinfection functions as needed.

[0049] Accordingly, charging modules can be freely arranged to suit the shape of the space or the user's lifestyle patterns, and unused functions can be separated for storage, thereby maximizing space utilization. Brief explanation of the drawing

[0051] FIG. 1 is a schematic perspective view showing the exterior of each module constituting a charging station according to an embodiment of the present invention. Specific details for implementing the invention

[0052] Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the invention, such detailed description is omitted.

[0053] In addition, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the present invention. These terms are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that a component is "connected," "combined," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but that another component may also be "connected," "combined," or "connected" between each component.

[0055] The present invention relates to a module-based charging station comprising a plurality of module blocks, wherein the module blocks can be arranged to be separated and combined through a common power bus and alignment mechanism.

[0056] The charging station of the present invention is characterized by implementing wired charging, wireless charging, and ultraviolet disinfection functions in the form of individual blocks, and being designed so that the user can freely combine and separate them as needed.

[0057] A charging station according to one embodiment of the present invention is called a 'Charger Collector' and can be used as a modular combination type charging system rather than a single type charger.

[0058] Hereinafter, the configuration of a charging station according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 1.

[0059] Conventional charger products perform only one of the functions, either wireless or wired charging, or cannot be customized for the user due to their fixed, integrated structure. However, by adopting an independent block structure, the charging station of the present invention allows users to freely arrange it according to the shape of the space or the usage environment, and provides a new concept of an integrated charging and disinfection system in which each block recognizes and functionally interoperates.

[0061] A charging station according to one embodiment of the present invention may include a wireless charging block module (10), a wired charging block module (20), and a disinfectant block module (30) as shown in FIG. 1. Each block module is equipped with an independent power control circuit and function, shares power through a common power bus, and can be stably coupled through an alignment mechanism using magnets and mechanical keys.

[0062] Through this modular structure, users can use a specific block independently as needed, or stack or arrange multiple blocks adjacently to configure an integrated charging environment.

[0063] The charging station according to the present invention includes a shielding layer and a heat dissipation structure in a common design to solve problems of electromagnetic interference, heat generation, and power distribution between blocks. In addition, power recognition and control signals are automatically synchronized when blocks are electrically coupled, which enables the user to simultaneously perform stable charging and disinfection functions without separate operation.

[0065] The wireless charging block module (10) is a rectangular module that includes a wireless power transmission method based on the Qi standard and a magnetic alignment function. The upper surface of the module is formed to allow a smartphone to be placed directly on it. When a smartphone is placed on it, the center of the coil is automatically aligned by a magnetic alignment ring magnet provided inside, thereby minimizing the alignment error between the charging coil and the transmission coil of the smartphone. This improves wireless charging efficiency, and allows the user to charge smoothly without any separate position adjustment.

[0066] A rectangular elastic gasket (14) is provided on the upper charging surface of the wireless charging block module (10), and coupling guide protrusions may be formed on the four corners of the elastic gasket (14) to help align the sterilizer block module (30) in the correct position when coupled. These protrusions absorb shock during coupling and increase the degree of contact between modules, thereby allowing the sterilizer block module to be stably seated in the correct position.

[0067] More specifically, a wireless charging coil assembly having an operating frequency of 110 kHz to 205 kHz is embedded inside the wireless charging block module (10), and the output may include a range of 5W, 10W, 15W, and 30W. The coil is composed of a multilayer Litz wire, a ferrite sheet with a thickness of 0.3 mm to 1.0 mm is placed on the rear side, and a copper foil shielding layer with a thickness of several tens of micrometers is attached to the rear side. This reduces magnetic field leakage to the outside and minimizes interference with adjacent modules.

[0068] For heat dissipation, the lower part of the module may include an aluminum heat spreader with a thickness of 0.8 mm to 2.0 mm, and a base ventilation hole for internal air circulation may be further provided. The wireless charging block module (10) preferably includes an FOD (foreign object detection) function, and can ensure safety by automatically reducing the charging power when a metallic foreign object is detected.

[0069] Additionally, it is preferable to place a shielding layer (40) on the lower part of the wireless charging block module (10). This is to prevent electromagnetic interference or heat generation interactions between upper and lower modules when multiple modules are stacked and used. The shielding layer (40) is composed of a ferrite material or a conductive aluminum composite layer to block wireless charging signals from affecting the electronic circuits of other modules.

[0070] The wireless charging block module (10) according to the present embodiment does not merely perform a charging function, but also includes a module interlocking function capable of synchronizing power supply and control signals when a disinfectant block module (30) is combined on top. Accordingly, the wireless charging output is automatically reduced the moment the disinfectant block module is covered, thereby suppressing heat generation and ensuring safety during UV irradiation. This control method is a feature not found in general wireless chargers and provides a technical effect that simultaneously improves charging efficiency and safety.

[0072] The wired charging block module (20) is a module designed to solve structural problems of existing wired chargers, such as the cable bending excessively or terminal contact failure occurring during use.

[0073] In particular, to fundamentally improve terminal deformation, poor connection, and cable tangling problems that occur when moving or pulling the smartphone while charging, a cable separation space (25) is included. This space allows excess cables to be wound and organized inside, preventing the wires from getting tangled or exposed to the outside, which would spoil the aesthetics.

[0074] Additionally, the wired charging block module (20) includes a smartphone stand (21) on the upper side and is configured to stably support the smartphone while charging. The smartphone stand (21) can be adjusted to an angle desired by the user, such as 30°, 45°, or 60°, and the support surface is formed of rubber, UV-resistant PC, or a silicone anti-slip pad to prevent the smartphone from sliding. A protrusion or an uneven structure can be formed to increase friction, and such a structure prevents the smartphone from falling or shaking due to micro-vibrations while charging.

[0075] Two or more USB-C type ports may be provided for wired charging, and each port supports PD 3.0 or PPS standards to handle a voltage range from 5V to 20V. A cable exit light-blocking channel (23) is provided at the part where the cable comes out of the block, so as to block internal UV light from leaking out when combined with the sterilizer block module (30) described later.

[0076] The wired charging block module (20) preferably includes a protection circuit to prevent overheating and can perform a stepwise current limiting function that reduces the current in increments of 0.5A when the temperature of the port reaches 55℃. This allows for stable control of heat generation to prevent damage to the terminal and overheating.

[0077] The wired charging block module (20) according to the present embodiment goes beyond a simple power supply function and features a cable management and light-blocking structure to organize the user's charging environment and improve safety. In particular, by blocking light leakage that may occur at the cable exit when combined with the disinfectant block module (30), user safety accidents caused by exposure to ultraviolet rays can be prevented. In addition, the heat control circuit inside the module and the material selection of the smartphone stand are designed so that heat is not concentrated even during long-term charging, thereby increasing charging efficiency and extending the product lifespan.

[0079] The disinfector block module (30) is a module configured to allow charging and disinfection of a smartphone via wired or wireless methods. The entire operation of this module is controlled by an internal disinfector control unit (31), and it performs the function of sterilizing and disinfecting the surface of the smartphone using an ultraviolet (UV) LED.

[0080] According to a preferred embodiment of the present invention, the disinfector block module (30) is formed with a structure that is similar in appearance to a rectangular block but has an open bottom. Through this, the user can cover a smartphone that is being charged by placing the module over the top of the wireless charging block module (10) or the wired charging block module (20), and the disinfection function is automatically activated when the cover is closed.

[0081] The main body is constructed of PC-ABS material with excellent heat resistance, and the inner surface is provided with an anodized reflector or PTFE liner having a reflectivity of 70% or more, preferably 80% or more, so that ultraviolet rays are evenly reflected and distributed.

[0082] Inside, a transparent window (32) may be further provided to check the status during disinfection, and the transparent window (32) is made of transparent quartz or a UV-blocking polymer so as not to leak UV to the outside, and includes a light-blocking window with a blind structure that restricts external visibility.

[0083] A disinfection UV-LED panel may be composed of a UV-C LED with a wavelength of 260 nm to 280 nm and an auxiliary UV-A LED with a wavelength of 365 nm to 405 nm, and the total light output of the LEDs is preferably in the range of 20 mW to 400 mW.

[0084] In addition, safety during use is ensured by including various detection devices such as a temperature sensor, a foreign object detection sensor, and an interlock sensor. The temperature sensor is connected to the sterilizer control unit (31) to detect the surface temperature of the smartphone in real time, and the foreign object detection sensor uses an infrared ToF sensor or a photodiode to automatically stop UV emission when the smartphone is not inside.

[0085] The interlock sensor prevents power from being supplied to the UV-LED if the disinfectant block module (30) is not completely sealed, thereby fundamentally preventing accidents in which the user's eyes or skin are exposed to ultraviolet rays.

[0086] The disinfector control unit (31) detects the open / closed state of the disinfector block module (30) in real time and immediately blocks the UV output when it is opened, and can automatically adjust the UV power by comprehensively determining the Foreign Object Detection (FOD) function of the Qi stack of the wireless charging block module and the metal degradation detection result of the wired charging port.

[0087] Additionally, the user can check the progress of charging and disinfection at a glance through the status display window or external LED indicator (33) of the disinfector block module (30), and can visually recognize the external LED lighting pattern when a warning situation, such as a rise in temperature, occurs.

[0088] Unlike a general portable UV sterilizer, the sterilizer block module (30) according to the present embodiment operates in conjunction with a charging function, so it has the unique advantage of being able to perform hygiene management even during the charging process. In addition, by controlling the balance between the ultraviolet output and the charging power in real time, it prevents heat generation and overcurrent problems, and is designed so that the sterilization function operates automatically only when safety conditions are satisfied without user error, thereby ensuring high safety and user convenience at the same time.

[0089] The charging station of the present invention can be operated in a standalone wireless charging mode, a standalone wired charging mode, a disinfection-only mode, and a mode for simultaneous charging and disinfection. Additionally, the user can control the function to automatically terminate by setting a desired time range using a timer.

[0090] In the mode where wireless charging and disinfection are performed simultaneously,

[0091] After the user places a smartphone on the top plate of the wireless charging block module (10) and covers it with the sterilizer block module (30) to seal the elastic gasket (14), the interlock sensor detects the closed state.

[0092] ② When the disinfector block module (30) is completely closed, the interlock signal is activated, and the disinfector control unit (31) recognizes this and prepares to drive the UV-LED.

[0093] ③ The UV-LED can be driven only when the coil temperature (Tcoil) is 50℃ or lower and the estimated smartphone battery temperature (Tbat) is 42℃ or lower, and the temperature detection result is transmitted to the control unit in real time.

[0094] ④ The UV-C output is attenuated linearly according to the wireless charging power, and for example, when the wireless charging power is 10W or more, the UV-C output is automatically limited to 40% or less of the rated power.

[0095] ⑤ The disinfection time and target irradiation dose (Dtarget) can be pre-set by the user and are automatically calculated in the range of 2 mJ / cm² to 20 mJ / cm² by considering the LED light output, irradiation distance, and reflectance.

[0097] Similarly, in the mode where wired charging and disinfection are performed simultaneously,

[0098] ① The user connects the charging cable to the smartphone, places the smartphone on the smartphone stand (21), and covers it with the sterilizer block module (30) to seal it.

[0099] ② When the interlock sensor detects that it is closed, disinfection mode is activated, and

[0100] ③ The UV-LED is driven when the estimated battery temperature of the smartphone is 42℃ or lower.

[0101] ④ When the output power of the port exceeds 27W, the UV-C output is reduced in 25% increments to prevent overheating, and when overheating is detected, the current per port is reduced in 0.5A increments to ensure stability.

[0103] This control logic simultaneously solves the problems of thermal overload and electromagnetic interference during the charging process, while achieving an optimal balance of charging efficiency and disinfection performance. In addition, the control unit (31) can improve the reliability and durability of the entire system by integrally analyzing the status data of each module and adjusting the charging speed and ultraviolet irradiation amount in real time.

[0104] According to a preferred embodiment of the present invention, a plurality of block modules operate independently while sharing a single common power bus. Accordingly, the supply of power and the exchange of control signals between the wireless charging block module (10), the wired charging block module (20), and the disinfectant block module (30) can be integrated. When the wireless charging block module is operating, the disinfectant block module automatically reduces the power consumption, and conversely, when only the disinfectant block module is operating, the priority of the total power is assigned to the disinfectant control unit (31), thereby enabling stable power distribution.

[0105] This dynamic power distribution is a technology not implemented in conventional charger systems, offering the advantage of simultaneously ensuring power efficiency and stability.

[0106] Furthermore, not only are multiple modules simply connected, but the operation mode can be automatically switched by recognizing the connection position and direction of each module.

[0107] For example, when the disinfectant block module is combined with the wireless charging block module, the “Wireless Charging + Disinfection Mode” is automatically selected, and when combined with the wired charging block module, it automatically switches to the “Wired Charging + Disinfection Mode.”

[0108] This structure maximizes user convenience by allowing the operating mode to be switched simply by the arrangement of modules, without the user having to operate or configure separate switches. In addition, through a common power bus design, current, voltage, and temperature data of each module can be shared in real time, enabling the protection circuit of the entire system to operate integrally and making it possible to implement an intelligent charging station that prevents overheating and overload.

[0110] As shown in the embodiment on the right side of FIG. 1, the present invention can be used as a stacked structure of block modules. Since electromagnetic interference or thermal interference may occur between multiple block modules when stacked adjacently, it is preferable to provide a shielding plate (40) at the bottom of each of the wireless charging block module (10), wired charging block module (20), and sterilizer block module (30).

[0111] The shielding plate (40) is composed of a ferrite and aluminum composite material, effectively blocking electromagnetic interference and minimizing high-frequency power loss.

[0112] Since the three types of block modules can be separated independently and utilized in any arrangement, users can freely position them to fit various spatial forms, such as desks, beds, and stands.

[0113] This structure provides a new user experience (UX) as a space-customized charging and disinfection station, rather than a simple charger.

[0114] Small neodymium magnets and asymmetric mechanical keys can be used for joining and aligning each block module, and the magnets help automatically recognize the joining position.

[0115] In addition, power supply and data communication can be immediately activated by using a docking rail / base plate (magnet + mechanical key + power bus) structure in which power contacts are automatically connected simultaneously with magnetic coupling.

[0116] This magnetic alignment structure ensures that blocks are always aligned in the same polarity direction, even if the user combines them arbitrarily, thereby preventing mis-connections or short circuits. Furthermore, the coupling signals between modules are shared along with various sensor data, such as temperature, light detection, and magnetic detection, playing a role in further enhancing the safety and efficiency of the entire system.

[0118] The modular charging station according to the present invention provides wired and wireless charging functions and ultraviolet disinfection functions in a single system, thereby simultaneously achieving technical effects such as ① improved space utilization, ② automation of hygiene management functions, ③ improvement of electromagnetic interference and heat generation problems, ④ autonomous power distribution control, and ⑤ enhanced user safety.

[0119] In particular, through the inter-block coupling structure and autonomous control system, disinfection can be safely performed even during charging, and it provides an intelligent charging environment where the operating mode automatically changes according to the combination of modules without any separate operation by the user.

[0120] This configuration can be applied in various environments, such as homes, offices, and accommodation facilities, and can also be applied to public charging stations or wireless charging systems for vehicles in the future.

[0121] In summary, the present invention goes beyond the concept of a simple charger and proposes a next-generation modular charging infrastructure technology that integrates user-customized hygiene management and energy efficiency.

[0122] Through this, users can experience a clean and efficient charging environment, and manufacturers secure industrial application possibilities to expand their product lineups through various module combinations. Explanation of the symbols
