A few days ago, the Mercedes-Benz VISION EQXX concept car visited China for the first time and came to Shanghai. Mercedes-Benz VISION EQXX declares the attitude of Mercedes-Benz . In the new energy industry, the leadership is not catching up, but leading! The attitude of the inventor of the car - this is the electric car I want to make and bring the concept of "energy efficiency is hard currency".
In the Science and Technology Day lecture that day, we did not hear the usual words of electric vehicles, did not talk about intelligent driving on large screens, nor did we have the best within millions. What we heard the most was Mercedes-Benz’s thoughts on electric vehicles and future travel.
, energy efficiency is the new hard currency. It does not rely on the accumulation of batteries to achieve a range of 1,200 kilometers.
VISION EQXX concept car has a new electric drive system independently developed. The new 900-volt high-voltage battery pack jointly developed by the Mercedes-Benz F1 team. With the advanced anode chemical process, an amazing energy density of nearly 400 watt-hours/liter is achieved with an ultra-low weight of 495 kg. The powerful electric drive system can directly transfer 95% of the battery energy to the wheels. At the same time, the roof of 117 solar cells can reserve electricity equivalent to 25 kilometers for long-distance travel. The VISION EQXX concept car is also equipped with an "energy efficiency assistant system", which can give the most efficient travel and driving suggestions based on information such as energy flow, terrain, electricity, and even the direction and intensity of the wind and the sun, and improve driving efficiency. Thanks to the above-mentioned high-energy-efficient technology, the VISION EQXX concept car achieved an extraordinary performance of 1,202 kilometers on a single charge in the real road conditions challenge in June this year with an ultra-low power consumption of 8.3 kWh per 100 kilometers. The reason why the energy density of
has increased significantly is partly due to the rapid development of the anode chemical process. Thanks to its higher silicon content and advanced ingredients, such batteries can store more energy than conventional batteries. Another factor driving the increase in energy density is the highly integrated battery pack. This platform, jointly developed by Mercedes-Benz R&D department and High Performance Power Systems Co., Ltd., creates more space for the battery and further reduces the overall weight.
VISION The aerodynamic optimization of the EQXX concept car perfectly presents the fusion of technology and aesthetics. Digital simulation technology further helps it to create an astonishing wind resistance coefficient as low as 0.17. The retractable active rear diffuser is seamlessly integrated into the body after being folded. It is combined with tires with ultra-low rolling resistance and aerodynamic optimization, effectively improving range. At the same time, the VISION EQXX concept car has an advanced thermal management system. Thanks to the innovative "on-demand cooling" thermal management concept, it achieves excellent energy efficiency and cooling effects through passive cooling of external airflow and timely active cooling system. Its multi-source heat pump fully absorbs heat from the drive system and externally, and generates heat from the cockpit with extremely low energy consumption.
2. Luxury is not the accumulation of luxury materials, environmentally friendly materials bring more ways to play.
VISION EQXX concept car adopts the eye-catching silver appearance of Alubeam, with the roof just like a smooth greenhouse dome, flowing to the rear of the car gracefully like water droplets. At the same time, the VISION EQXX concept car is equipped with a large 47.5-inch screen with a resolution of 8K (7,680×660 pixels), which can allocate power according to the needs of specific areas of the screen and reduce screen power consumption. The human-computer interaction system , created by the game engine interface, operates in a "neuromorphic computing" way that simulates the human brain, effectively reducing the energy consumption of information processing and doubles the response speed.
In addition, the VISION EQXX concept car is widely equipped with sustainable materials, such as the door handles are made of biodegradable pure plant materials, the seats are made of cacti raw materials or mushroom mycelium, and the carpet is woven with 100% bamboo fiber . VISION EQXX concept car also widely uses recycled and reprocessed environmentally friendly materials, such as the glossy fabric of floors and door trims derived from the recycled PET bottle . The designer applied Dinamica (38% recycled PET) material to the ceiling, connecting the upper edge of the integrated screen to the door and ceiling to create a wraparound effect.The interior also features UBQ materials, a sustainable plastic alternative made from waste recycled from home and urban landfills.
, BIONEQXX™ casting + Bioric simulation
BIONEQXXTM integrated casting is currently the largest aluminum structural casting of Mercedes-Benz and is also the main component of the rear of VISION EQXX. Mercedes-Benz uses pure digital technology and uses unique software methods in the automotive industry to complete internal independent development. The castings were finally loaded into the compact interior space and achieved the best functional results. The most important criterion for measuring structural parts is to achieve extremely high stiffness and excellent collision performance. The advantage of BIONEQXXTM integrated casting is that it enables functional integration in a single, extremely light component without the need to connect to multiple components.
, Neuromorphic calculation - think like the human brain
Although this time, the system's response capacity has not been mentioned, the system's response capacity has been improved by 5 to 10 times. The hardware can run pulse neural network , dispersing pulses to program and calculate the information process, and trigger energy consumption only when the pulse signal appears, effectively reducing energy consumption by orders of magnitude.
VISION EQXX concept car uses a 47.5-inch screen, which makes it unique in the way it works intuitively and imitates the thinking of the human brain. The thin and light mini LED display is equipped with 8K (7680x660 pixels) resolution, which is the door connecting the drivers and passengers in the car to the outside world. As a powerful car guide, Nebula Assistant recalls Mercedes Jelinek, the same name as the Mercedes brand. This function can be adjusted according to the driver's needs and carries care for the driving experience of each passenger.
From this car, Mercedes-Benz also demonstrated a breakthrough in the process. The full stack self-development is driven by new "cross-departmental, overall collaborative promotion" and digital drive. Therefore, the whole vehicle was launched in 18 months, and there are no shortcomings in the core indicators of the vehicle, and it has met the conditions for mass production vehicles. Faced with such innovations, there are still fewer models that can compete with it at present.
You can see that there is no shortcut to mechanical manufacturing, and what is required is long-term accumulation and precipitation. The traditional powerful technical moat is still stunning, with strong potential energy!
