Mercedes  EQXX, The Secret of The Battery

Mercedes EQXX, The Secret of The Battery

The Mercedes Vision EQXX is developed from the ground up to minimize fuel consumption. As the primary component of an electric vehicle, the battery has also been meticulously engineered to maximize its performance.

The 100 kWh battery of the Mercedes Vision EQXX, which has proportions so tiny that it can be installed in the brand’s smallest cars, is capable of 1,000 kilometers of autonomy.

Presented digitally at CES 2022 in Las Vegas, the Mercedes Vision EQXX concept is a laboratory from which innovations suitable to the brand’s series cars will be extracted. In addition to the aerodynamics and all of the components that comprise the vehicle’s drivetrain, the battery plays a crucial role.

It is 30 percent lighter and 50 percent less bulky than EQS, and its chemistry has been thoroughly examined to improve the total vehicle economy. With 100 kWh of capacity, it has a range of one thousand kilometers per charge.

Mercedes said during the unveiling of the EQXX that the battery that powers the vehicle’s electric drive system makes it ” the most fuel-efficient and aerodynamic vehicle it has ever produced” According to Markus Schaefer, Daimler’s chief technology officer, this vehicle represents “the protagonist of technical advancement” for the German company. Mercedes has worked diligently over the last several years; our goal is not merely to stay up with the competition, but to surpass it.

In addition to the technological advancements made to the electric motor and inverter, there have also been advancements made to the battery, its packaging and the thermal management system. Its chemistry has been improved with the assistance of Formula 1 experts from Mercedes-High AMG’s Performance Powertrain section in the United Kingdom.

The result is a battery that is 50% smaller and 30% lighter than the one found in the Mercedes EQS, the brand’s current flagship vehicle. It is also tiny enough to be compatible with the brand’s most compact versions.

Its energy usage will be less than 10 kWh/100 km, which is a substantial improvement over, for instance, the average consumption of the Tesla Model S 60, which is 18.1 kWh/100 km. Schaefer explains that the goal of the initiative was to have our designers and engineers collaborate across a number of fields and professions to share the finest ideas.

To accomplish this efficiency, researchers boosted the silicon concentration in the anode of the battery cells and changed the packaging to accommodate a greater number of cells, hence decreasing the assembly’s total weight. A novel casting technology was employed to build an enormous aluminum component similar to what Tesla is doing at its Shanghai Gigafactory to produce the rear subframe of the Model Y in a single piece.

The thermal management system aids in minimizing the battery’s energy losses. A mixture of aerodynamic shutters, coolant valves, and water pumps maintains the appropriate temperature of the electric transmission. A cooling plate inserted in the vehicle’s floor makes use of the air that runs down the bottom, increasing the range by 19 kilometers.

Specifications on the Mercedes Vision EQXX battery.

The 117 solar cells installed on the Vision EQXX’s roof are connected to a lithium iron phosphate (LFP) battery that is distinct from the traction battery. This battery powers several automotive functions, including the temperature control fan, lighting, infotainment system, and other accessories. Using a separate battery to power these devices decreases the voltage of the primary battery, hence improving the vehicle’s range.

Mercedes will submit the prototype to a variety of real-world settings throughout the middle of this year. In two to three years, certain components of the prototype will be accessible in Mercedes production automobiles.

Schaefer did not say when the 1,000-kilometer autonomy battery would be introduced. He said that “we will likely be the first to demonstrate a vehicle with a range of 1,000 kilometers with such a compact battery”

The introduction of a vehicle with these features is a choice that will be made by the market after client requirements and their willingness to pay for them have been determined.
