Embedded wireless charging refers to a wireless charging system that is integrated into a surface or object, allowing devices to be charged simply by placing them on that surface without the need for visible cables or connectors.
Seamless Integration:
The charging components (such as coils and circuitry) are embedded within furniture (e.g., desks, tables, nightstands), vehicles (e.g., car consoles), or public infrastructure (e.g., airport lounges, coffee shop counters).
Example: A hotel nightstand with an embedded Wireless Charger lets guests charge their phones by placing them on the surface, with no need for external pads or cables.
Convenience and Aesthetics:
Eliminates clutter from cables and adapters, creating a cleaner, more organized environment.
Enhances user experience by enabling "drop-and-charge" functionality in everyday spaces.
Safety and Durability:
Embedded designs often include protective features like foreign object detection (FOD) to prevent overheating caused by metallic items (e.g., keys, coins) placed on the charging surface.
Enclosed components are shielded from dust, spills, and physical damage, improving longevity.
Versatility:
Supports multiple devices (smartphones, tablets, earbuds) that comply with wireless charging standards like Qi.
Can be combined with other smart features, such as LED indicators for charging status or temperature control for heated surfaces (e.g., keeping coffee cups warm while charging a phone).
Technical Basis:
Electromagnetic Induction: Most embedded systems use coils to generate an alternating magnetic field, which induces a current in the receiver coil of the device being charged.
Standards Compliance: Adheres to protocols like Qi (developed by the Wireless Power Consortium) to ensure compatibility across devices and manufacturers.
Countertop Wireless Charger
This type of product usually adopts a hidden design, which can be directly embedded on the desktop or under the tabletop, and the charging area is marked by indicator lights or table stickers. For example, a certain model supports simultaneous 15W fast charging for three devices (Qi2 standard), with an input voltage of 15V/4.33A, suitable for scenarios such as office desks and coffee tables. Its advantage lies in keeping the desktop clean, no need to plug or unplug cables when charging, and some products integrate NFC function, which can realize device proximity sensing to start vehicles or make payments.
Furniture Wireless Charger
This type of product integrates wireless charging modules into furniture, such as bedside tables, sofas, dining tables, etc. For example:
Wireless charging technology across the air: With a penetration distance of 30mm (made of materials such as wood and marble), the desktop is designed without a charging board. The device is hidden under the table and can be charged simply by placing a mobile phone.
Modular installation: Users can self slot and embed Qi standard modules, and use PD fast charging modules to achieve multi device charging (such as mobile phones and headphones). The power can reach 15W to 50W according to the module configuration.
Additional features: Some products integrate magnetic terminal wires, LED indicator lights, overcurrent and thermal protection, etc., improving convenience and safety of use.
Wireless Charger in Furniture
Similar to 'Furniture Wireless Charger', but emphasizing more on the native integration of furniture and chargers. For example:
Car wireless charging: Supports 50W fast charging (compatible with proprietary protocols such as Huawei and Xiaomi), the coil can be moved to adapt to different device locations, and integrates NFC to start the vehicle function.
Whole house wireless charging deployment: Magsafe module is embedded in the slot of the trimming machine, combined with PD fast charging module to achieve multi scene coverage (such as coffee table, dining table, workbench), and the power supply voltage is adjusted according to the power demand (9V to 20V).
Wireless Charging Surface
Refers to any flat surface with wireless charging function, including but not limited to:
Public area applications: Wireless charging modules are embedded in the desktops of airports and cafes, supporting instant charging.
Technical upgrade direction: Qi2.2 standard is expected to improve charging efficiency and compatibility, and may support higher power (such as over 50W) and longer distances (such as millimeter to centimeter penetration) in the future.
Material innovation: Developing flexible charging coils that can be embedded in furniture, reducing installation difficulty while maintaining surface aesthetics.
Example Use Case:
A restaurant embeds wireless chargers into its tables, allowing customers to charge their phones while dining without searching for outlets or dealing with tangled cords. This enhances customer satisfaction and positions the venue as tech-friendly.
