Mercedes-Benz EQE SUV makes its debut together with AMG model


Mercedes-Benz revealed the most recent member of its electrical lineup, the EQE SUV—which the corporate positions because the multipurpose variant of the EQE govt sedan. AMG additionally offered the 2024 AMG EQE SUV, the efficiency model of the EQE SUV and the primary all-electric efficiency SUV from Mercedes-AMG.


EQE SUV (European mannequin)

The EQE SUV is among the most spacious representatives of its class, but it’s extra compact than the EQE Sedan; at 119.3 inches, it has a wheelbase that’s 3.5 inches shorter. The exterior dimensions are 191.5/76.4/66.4 inches (size/width/peak).

Because the fourth mannequin after the 2 EQS and EQE Sedans, in addition to the EQS SUV, the EQE SUV makes use of the brand new all-electric platform. Relying on the car gear and configuration, WLTP ranges of greater than 550 kilometers (342 miles) may be anticipated for European autos (except for AMG fashions).

All EQE SUVs have an electrical drivetrain (eATS) on the rear axle. The variations with 4MATIC even have an eATS on the entrance axle. Within the 4MATIC fashions, the Torque Shift perform ensures clever, constantly variable distribution of drive torque between the rear and entrance electrical motors and thus using probably the most environment friendly eATS in every case. The modular drive idea allows excessive total efficiency and an extended vary.

To extend the vary additional, the electrical motor on the entrance axle may be utterly decoupled. This step is undertaken by what is called the Disconnect Unit (DCU). The clever disconnection system works full robotically relying on the driving state of affairs and the required output. At low masses, the DCU switches into 4×2 driving mode, and each the electrical motor and the related transmission on the entrance axle stop operation. This ensures that the drag losses in any other case usually skilled are largely eradicated.

The electrical motors on the entrance and rear axles are completely excited synchronous motors (PSM). On a PSM, the rotor of the AC motor is fitted with everlasting magnets and subsequently doesn’t must be provided with energy. The magnets—and thus the rotor—comply with the rotating alternating present area within the stator windings.

Within the EQE SUV, Mercedes-Benz makes use of a pull-in winding for a very sturdy magnetic area. The motor is known as synchronous as a result of the rotor turns on the similar fee because the magnetic area of the stator. The frequency is adjusted within the energy electronics inverters to the velocity necessities of the driving force. The benefits of this design embody excessive energy density, excessive effectivity and excessive energy fidelity. The motor on the rear axle could be very highly effective as a result of six-phase design: it has two windings with three phases every.

A water lance within the shaft of the rotor cools it from the within. Different cooling components within the cooling circuit are fins on the stator, a needle-shaped pin-fin construction on the inverter and a transmission oil cooler. This additionally brings extra effectivity throughout chilly driving, as a result of the warmth exchanger then serves to warmth the transmission oil and thus reduces friction within the transmission.

The EQE SUV provides a number of variants of power restoration by the use of recuperation. On this course of, the high-voltage battery is charged by changing the mechanical rotary movement into electrical power throughout overrun or braking mode. The driving force can manually choose the deceleration in overrun mode in three levels (D+, D, D-) in addition to the coasting perform through shift paddles behind the steering wheel. Additionally obtainable: DAuto.

ECO Help additionally provides situation-optimized recuperation; deceleration is so sturdy or weak that it finally ends in probably the most environment friendly driving type. Recuperative deceleration can also be used so far as doable for autos detected forward till they arrive to a standstill, for instance at site visitors lights. The driving force doesn’t must press the brake pedal for this; actually one-pedal driving.

The magnets are organized contained in the rotors in an NVH-optimized means (referred to as ‘lamination’). This additionally reduces using uncommon earths. The form of the winding, the stator tilt, additionally causes much less vibration, particularly at low speeds. The coils within the stator are at an angle in relation to the everlasting magnets of the rotor. In any other case, what is called cogging torque might happen, they’d result in slight however disagreeable vibrations when driving very slowly.

As well as, the eATS have a particular foam mat throughout as an NVH cowl. The inverter cowl has a sandwich development of three metallic and plastic layers. The eATS are doubly decoupled from the physique through elastomer bearings: on the entrance axle reverse a supporting body and this in opposition to the physique, on the rear axle with a subframe.

Extremely efficient spring/mass elements present steady sound insulation from the cross member underneath the windshield to the ground of the load compartment. Acoustic foams are inserted into many members throughout development of the bodyshell.

The electrical refrigerant compressor has an NVH cowl as encapsulation. Within the rear-wheel-drive EQE SUVs it is usually soft-suspended, whereas within the 4MATIC fashions it’s bolted on to the entrance eATS. The working technique of the refrigerant compressor additionally contributes to the low noise degree of the car. Sure rpm ranges at which disturbing resonances could also be audible when stationary or in a site visitors jam are prevented or rapidly handed via.

A DC quick charging system with a charging capability of as much as 170 kW is fitted on board for quick charging through direct present along with the usual 9.6 kW charging capability. Excessive charging currents may be maintained for a very long time via temperature and charging administration.

Battery. Within the EQE SUV, the lithium-ion battery consists of ten modules. This technology of batteries takes a giant step in the direction of the sustainability of cell chemistry: the optimized energetic materials consists of nickel, cobalt and manganese in a ratio of 8:1:1. This has decreased the cobalt content material to lower than ten %. The continual optimization of the recyclability is a part of Mercedes-Benz’s holistic battery technique. The intention is to have the ability to dispense solely with supplies comparable to cobalt via using revolutionary post-lithium-ion applied sciences.

The battery is built-in into the EQE SUV’s clever thermal administration system with warmth pump as customary. If the clever Navigation with Electrical Intelligence is activated, the battery is preheated or cooled as wanted whereas driving. Consequently, the temperature on the charging level is in an optimum vary for environment friendly charging. The specified temperature vary of the battery is achieved with the help of the cooling circuit and a PTC (Optimistic Temperature Coefficient) booster heater built-in into it.

The battery administration software program, which was developed in-house, permits updates over the air (OTA). On this means, the power administration of the EQE SUV stays up-to-date all through its complete life cycle.
