With the widespread adoption of smartphones and the rapid advancement of connected vehicle technology, in-vehicle wireless charging has transitioned from a premium accessory to a standard pre-installed feature in many new cars. The term "pre-installed" refers to components that are integrated by manufacturers into the vehicle's interior before production, typically positioned in easily accessible areas like the dashboard or armrest console. Unlike aftermarket solutions, these pre-installed wireless chargers are seamlessly incorporated into the vehicle's design, ensuring aesthetic harmony. They undergo rigorous automotive-grade testing, with higher standards for safety, stability, and compatibility with the entire vehicle system.
For both automakers and consumers, identifying a high-quality pre-installed in-car wireless charging system is crucial. Below, we will introduce several common wireless charging certifications and highlight their importance in the pre-installed vehicle sector.
1、What are the main authentication methods for wireless charging?
1) Qi certification: the mainstream standard of the world
Introduction: Qi (pronounced 'qi') is the most widely adopted wireless charging standard developed by the Wireless Power Consortium (WPC). Currently, the vast majority of wireless charging-enabled smartphones on the market are compatible with the Qi standard.
Certification requirements: Qi certification mandates that products comply with WPC's stringent specifications, covering charging power, efficiency, electromagnetic compatibility (EMC), and safety features such as foreign object detection (FOD) and temperature rise control.
The significance of pre-installed in-vehicle wireless charging: For automakers, adopting Qi-certified modules enables seamless smartphone compatibility, delivering a worry-free "plug-and-charge" experience. Moreover, Qi certification minimizes electromagnetic interference with other in-vehicle electronics, meeting the industry's stringent electromagnetic compatibility standards and ensuring driving safety. The Qi logo displayed on the dashboard or center console reflects the vehicle's quality and reliability.
2)Powermat certification: a supplementary standard for specific scenarios
Introduction: Powermat is a wireless charging standard based on inductive charging technology, developed by Powermat Technologies.
Certification requirements: The certification specifications also emphasize charging power, efficiency, and device compatibility.
Significance of pre-installed in-vehicle charging: While its ecosystem is less extensive than Qi's, it may be adopted in specific collaborations or early-stage vehicle designs. When automakers adopt this standard, they must also obtain certification to ensure reliable and consistent in-vehicle charging performance.
3)PMA Certification: Another Choice of Technical Route
Introduction: PMA (Power Matters Alliance) is another wireless charging standard, with a technical foundation distinct from Qi and Powermat.
Certification requirements: PMA certification also covers specifications for power, efficiency, and safety.
Significance of pre-installed vehicle systems: Notably, to advance industry standardization, PMA later merged with A4WP (Alliance for Wireless Power) to form the AirFuel Alliance. The new alliance not only promotes magnetic resonance technology but also actively develops related standards. For the pre-installed market, understanding this evolutionary history helps identify the technical solutions adopted by different vehicle models across eras.
2、The Uniqueness of Pre-installed Car Wireless Charging Certification
Unlike wireless chargers in consumer electronics, pre-installed in-vehicle wireless chargers face more severe challenges, making their certification testing more complex.
lExtreme environmental reliability: The system must withstand temperature fluctuations from-40°C to 85°C or beyond, ensuring stable operation in both extreme cold and scorching heat.
lExceptional shock resistance and durability: Maintains charging performance and structural integrity even under vehicle vibrations.
lEnhanced safety standards: The system must feature more sensitive foreign object detection to prevent metal items like keys or coins from being accidentally heated during vehicle jolts, which could pose risks. Additionally, overvoltage, overcurrent, and overheating protection must be fully reliable.
lComplex electromagnetic compatibility (EMC): The system must not interfere with the normal operation of in-vehicle electronic systems such as GPS, car radios, and critical controllers (e.g., ECU), while also being immune to interference from other vehicle components.
Therefore, a high-quality pre-installed in-vehicle wireless charger must not only pass the general wireless charging certification mentioned above, but also comply with industry-specific standards like ISO 16750 (Road Vehicles-Environmental Conditions and Tests for Electrical and Electronic Equipment).
3. Certification is the cornerstone of quality and safety
For consumers choosing a car with pre-installed wireless charging, checking for Qi or similar certifications on the dashboard is a key factor in selecting a safe, efficient, and compatible vehicle. These certifications indicate the system has met international standards, making it a reliable 'energy station on the go' you can trust.
For automakers and Tier 1 suppliers, obtaining authoritative certification for pre-installed in-vehicle wireless charging modules serves not only as a market entry requirement but also as a demonstration of responsibility for brand reputation and consumer safety. In an era where smart cockpits have become a core selling point, a rigorously certified wireless charging system with exceptional user experience is undoubtedly a key detail in enhancing customer satisfaction and brand technological appeal.
