New Mercedes EQE Features Aluminum Sheet & Extrusions

The Mercedes-AMG EQE sedan is the latest edition to the OEM’s growing portfolio of battery-electric performance models. The EQE is based on the electric-exclusive Mercedes architecture of the luxury and premium class (EVA2). The new EQE offers a performance-oriented drive concept with two electric motors. The powerful electric drivetrain (eATS), with a motor on each of the axles, also offers fully variable all-wheel drive, which optimally transmits the drive power to the asphalt under all driving conditions. The vehicle produces an impressive power output of 677 hp and 738 lb-ft when equipped with the AMG Dynamic Plus Package and boost function.

“With the new model, we are expanding our range with a purely electrically powered performance vehicle and are thus addressing additional target groups. The AMG EQE focuses on sportiness and impressive driving dynamics,” said Philipp Schiemer, chairman of the board of management of Mercedes-AMG GmbH.

Aluminum is used throughout the design of the EV. Namely, the sedan boasts an aluminum structure, which helps make the vehicle lightweight and flexible. Furthermore, the new aluminum body makes the car more aerodynamic, and the smooth use of aluminum can be seen in the EQE’s stealth exterior bow design.

Battery Protected with Aluminum

The quick charging battery can charge with up to 170 kW at fast charging stations with direct current, so electricity for 112 miles can be recharged in 15 minutes. It also has an onboard charger, so that the battery can be charged at home or public charging stations with alternating current. The battery design aims to ensure the optimum battery operating temperature under all operating conditions. The aluminum extrusions of the battery frame have defined cavities through which the coolant flows. All in all, the intelligent temperature and charging management ensures that high charging currents can be maintained for a long time.

The battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminum profile on the side. During extrusion, a heated block of metal is pushed through the dies and turns into an endless section, which is then cut to fit. This makes highly complex profiles that are precisely tailored to the requirements possible. The housing with energy absorbing structures at the front and side as well as a rigid, double-walled base plate provide additional protection for the modules.

In addition, there is a separate, multi-level safety system for everyday operation. This includes, for example, temperature, voltage or insulation monitoring. If a fault occurs, the battery switches off. Crash monitoring when stationary (during DC charging) is also standard.

High Tech Features

One new feature in the vehicle is the possibility to install updates for the battery management system over-the-air for continuous improvements over the life cycle.  Also, the AMG EQE also features an AMG-specific wiring harness adapted to the higher performance capability. A major advancement in sustainability has been achieved in the cell chemistry: the cobalt content is reduced to ten percent. The optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1.

More Vehicle Specifications

  • The AMG EQE is a new model based on the all-electric EQE 350
  • Two electric motors produce 617 horsepower, and all-wheel drive is standard
  • According to Mercedes, acceleration from 0-60 mph takes 3.2 seconds
  • The car’s estimated range reaches up to 372 miles

The AMG EQE is scheduled to reach U.S. dealerships in early 2023.
