In the new generation of the Audi A8, codenamed D5, the integration of L3 autonomous driving technology has sparked widespread interest. Among its features, the hybrid version also incorporates wireless charging technology—though it's important to clarify that this is not the same as the wireless charging commonly seen in smartphones or other devices. Instead, it’s a vehicle-specific system designed for convenience and efficiency.
The Audi A8L e-tron is powered by a 3.0T turbocharged engine paired with an 8-speed automatic transmission, forming a robust powertrain that aligns with similar hybrid systems from BMW, Mercedes-Benz, and Porsche. What sets it apart is the integration of an electric motor within the automatic transmission, allowing for seamless hybrid operation. This innovation was pioneered by ZF, a German company that played a key role in bringing such advanced transmissions to market.

Compared to Japanese manufacturers' approaches, German automakers still emphasize performance and engineering excellence. Even though the hybrid system allows for short-range electric driving, the car quickly switches back to traditional power when more acceleration is needed. This ensures that drivers experience the dynamic performance expected from luxury vehicles. Meanwhile, Japanese brands like Lexus have started to focus more on balancing fuel efficiency with driving enjoyment, as seen in the 10-speed automatic used in the Lexus LC.

The electrical components of the hybrid system are well-established, with the high-voltage cable connected to a lithium-ion battery. While a 50 km all-electric range may not seem impressive on paper, it meets upcoming European emission standards. The traditional charging methods include engine-driven generators (48V), regenerative braking, and plug-in charging. This model marks Audi’s first attempt at wireless charging, which requires a dedicated parking space equipped with the necessary infrastructure. Although wireless charging is likely to become a standard urban feature in the future, its widespread adoption is still in the early stages.

The wireless charging system delivers up to 3.6 kW of power, using a secondary coil located beneath the front axle to receive energy. When the vehicle is parked, the magnetic field only activates once the charging pedestal is raised. During idle times, the system remains completely isolated, ensuring safety. Audi claims that their wireless charging technology has achieved over 90% efficiency, demonstrating a high level of maturity.
While Audi often refers to its electric models as "e-trons," the pure electric mode in German hybrid technology still lags behind in terms of power and efficiency. In comparison, BYD’s hybrid models are not necessarily inferior. The current market offerings reflect decisions made years ago, but with stricter emissions regulations and potential bans on internal combustion engines in the near future, German manufacturers are accelerating their shift toward electrification. Massive R&D investments are now being redirected from traditional platforms to new energy technologies.
Looking ahead, Audi plans to launch an SUV with a 500 km range, filling a growing gap in the premium electric vehicle market. As consumers seek alternatives beyond Tesla, the demand for high-quality, innovative electric vehicles continues to rise.
Portable Projector
The so-called portable projector, also known as pocket projector, mainly through the 3M LCOS RGB three-color projector and decoding technology, the traditional huge projector is compact and portable, making the projection technology closer to life and entertainment.
Advantages compared with traditional projectors:
1. Small size, light weight, easy to carry.
2. Low calorific value and low noise.
3. The price is relatively cheap.
4. Most models support wireless connection through software projection.
Applicable fields:
1. Replace some functions of TV: some machines can have built-in CMMB function, or can be directly connected to the set-top box to put TV, which can be used as a 21-inch TV during the day and a 60-100-inch TV at night (Note: Because of lumen and resolution issues, lumens during the day If the degree is not enough, it must be projected at a close distance) to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
2. Business trip: Portable projectors are easy to carry because of their small size and light weight. When you need to display computer content or mobile phone content, you only need to connect the portable projector to achieve the demonstration effect.
3. Private space: For dormitory beds or small private spaces, in the absence of a computer, you can use a portable projector to project the content of your mobile phone to watch video pictures, etc., without staring at the mobile phone at close range.
