Mercedes-Benz announced that its concept car, the Vision EQXX, has a range of more than 1,000 kilometers. Mercedes-Benz accomplished this on a single charge.
Test drives are held in Europe, and this street connects the Mercedes-Benz Sindelfingen R&D center in southwestErn Germany with the Côte d'Azur in the resort city of southern France. Mercedes explained that since the vehicle had to pass through the Alps, this section of the road was not an easy challenge.
Moreover, this kind of driving has considerable significance, because it focuses on daily driving rather than measuring brush miles. On highways, the acceleration exceeds 140 km / h, and driving on general national highways is also driven according to the speed limit. In addition, the temperature when driving is quite low at 3 to 15 ° C.
EQXX successfully traveled 1008 km to its destination. The driving time is 11 hours and 30 minutes, the average speed is 87.4 km / h, and the efficiency reaches 11.5 km / kWh. In terms of fuel economy, it's almost twice as much as the hyundai Ioiq 5 (5.1 km/kWh) and Tesla Model 3 (6.1 km/kWh).
The fact that it is capable of traveling more than 1,000 kilometers has also attracted attention. After driving, the EQXX has about 15% of its remaining battery and is able to continue for more than 100 kilometers.
The secret of efficiency lies in light weight and aerodynamic performance. The battery pack of the EQXX is 100kWh, which is similar to EQS, but increases the energy density, reducing the battery volume by 50% and the weight by 30%. The body consists of a lightweight chassis with F1 technology and a drag coefficient of only 0.1716 cd, which is lower than the EQS (0.20 cd).
In addition, 117 ultra-thin solar cells are installed on the roof, which can increase the range of about 25 kilometers, and the electrical energy generated by the power generation panels is used for air conditioning, lighting and infotainment systems, minimizing energy losses in the car.
Marcus Schaefer, Member of the Board of Directors of Mercedes-Benz and Chief Technology Officer (CTO) of Mercedes-Benz, said: "Maximizing the range of electric vehicles is most importantly efficient design. "Instead of increasing the capacity of the battery.
Foreign media predict that with the development of technology, there will be more and more cars in the future to be able to complete more than 1000 kilometers of endurance, although EQXX is only a concept car, its research and development and birth, is to travel 1000 kilometers on a single charge as the "goal", and to actually drive to achieve 1000 kilometers of endurance, not what test endurance. Therefore, Mercedes-Benz has made efforts in studying the strength of long endurance.
