Outlook on the Development Trend of Wireless Charging in 2025

From technological breakthroughs, application scenarios to industry ecology, wireless charging will undergo multidimensional changes in 2025. The following is a core trend analysis:

1、 Technological upgrade: high-frequency, efficient, and integrated

1. Popularization of high-frequency materials and devices

-GaN/SiC devices: Drive wireless charging frequency to exceed 1MHz, increase power density by 50%, and fast charging above 15W becomes mainstream.

-High frequency ferrite/nanocrystalline magnetic core: reduces losses to 30% of traditional materials, suitable for high-frequency requirements (such as TDK HF150 series).

2. Multi device charging and spatial freedom

-Multi coil dynamic array: supports placing 3+devices at any position for simultaneous charging (such as Apple MagSafe Duo upgraded version).

-Commercial use of magnetic resonance technology: mid-range (5-10cm) charging landing, solving the pain point of "contactless power supply" for wearable devices and home appliances.

3. Chip level integration solution

-Integrating driver/protection circuits between SoC chips at the transmitter and receiver, reducing module size by 40% (such as Infineon PSoC) ™ Series).

2、 Application scenario explosion: from consumer electronics to the Internet of Things

1. Consumer electronics

-Mobile phone/headphones: 50W+wireless fast charging is popular for mobile phones, and TWS headphone compartment supports reverse charging.

-Smart home: The desktop, desk lamp, and coffee table are equipped with hidden charging areas to achieve "contactless charging".

2. Automotive Electronics

-In car wireless charging for all areas: seats, armrests, and trunk all support charging, with power increased to 30W (meeting tablet/laptop needs).

-V2X wireless charging: Install road induction coils in parking lots/intersections, and automatically recharge electric vehicles when red lights are on (pilot project implemented).

3. Industry and Medical

-AGV robot: Implementing "charging during operation" in factory storage scenarios, with 24-hour uninterrupted operation.

-Implantable medical devices: In vivo blood glucose meters and pacemakers are wirelessly powered through skin patches, reducing the risk of battery replacement during surgery.

3、 Standardization and compatibility reshape the industry ecosystem

1. The Qi standard continues to evolve

-Qi v3.0 release: Integrating magnetic resonance and electromagnetic induction technology, unifying the 15W-30W medium power range standard.

-Private protocol convergence: Huawei SuperCharge, Xiaomi Mi Turbo, and others are gradually compatible with Qi, reducing vendor adaptation costs.

2. The rise of cross industry alliances

-Automotive Home Appliances Mobile Alliance: Jointly develop a home car multi scenario charging protocol (similar to CCS charging pile standards).

-The rise of Chinese standards: promoted by local standards such as GB/T 38775.1-202X, compatible with Qi but strengthening security (such as mandatory FOD detection).

4、 Challenges and coping strategies

1. Thermal management and safety

-At high power, VC heat plates and graphene heat dissipation films must be used, and certified according to AEC-Q200 (automotive regulations) and IEC 62368 (safety regulations).

2. Cost and Supply Chain

-Large scale production can reduce the cost of coils/magnetic materials (such as replacing ferrite with silicone magnetic cores), but it is necessary to deal with the risk of price fluctuations in rare earth materials.

3. User habit education

-Promote the "tailless" lifestyle and cultivate user dependence through the installation of charging boards in public places such as cafes and airports.

Summary and Suggestions

In 2025, wireless charging will present three major characteristics: high-frequency technology, ubiquitous scenarios, and global standards.

To manufacturers: Pre layout GaN/SiC devices and multi coil dynamic control technology;

To consumers: Pay attention to Qi v3.0 certified devices and prioritize products that are compatible with multiple protocols;

To investors: Focus on the automotive grade wireless charging and industrial wireless power supply solutions track.

In the future, wireless charging will not only be a "charging method", but also the cornerstone of space energy networks.
