The model electric car from Mercedes-Benz recently traveled 1,000 miles without recharging, with a battery of the same size as the current designs, a job celebrated by the manufacturer as a “pioneer” in the liberation war. The model, dubbed EQXX, “was first tested as a technology that would begin to arrive in a series of two to three years”, assured Markus Schäfer, head of research and development at the German group’s management board.
The vehicle traveled 1,008 kilometers between the group’s research center in Sindelfingen in southern Germany and Cassis on the French Riviera, Mercedes-Benz said. It arrived after about 12 hours on the road, equivalent to about 140 kilometers of remaining distance. With a 100-kilowatt hour (kWh) battery, the best model used an average of only 8.7 kWh per 100 km, less than half of the current comparable models. This experience shows that going down “around 10 kWh” is “quite real, even for a production vehicle in the near future”, said Mr. Schäfer.
A catalyst for success: aerodynamic profile, improved brake energy recovery, lighter batteries, solar panels on the roof to light board systems, new lighter material and transmission system with minimal energy loss. A car similar to the “most efficient fuel engine” could use “of course three to four liters” of fuel per 100 kilometers, according to the official. The electrical energy used is equivalent to “about a liter”, but the efficiency of traditional transmission is less profitable than electrical technology. The new battery chemistry actually allows it to make it thicker, thus being smaller and heavier with more capacity. This is the “next generation of chemistry” that the manufacturer intends to distribute more widely by 2024.
The electric S (EQS), the current leader of a German luxury car dealership sold for more than 100,000 euros, uses according to authorization between 16 and 17 kWh more than 100 kilometers – more often than not. . The distance is 780 km according to the WLTP standard. The Tesla competitor 3 and S model shows up to 650 kilometers of freedom according to this standard, for consumption which is generally estimated between 16 and 20 kWh per 100 kilometers.
