The newest vehicle in the German automaker’s EQ brand (and the latest one based on its Electric Vehicle Architecture platform) will be launched across Europe this August. Alongside this announcement, Mercedes-Benz detailed the technical specifications of the EQS – with a range of up to 479 miles (770km) on a 107.8kWh battery among its most notable features.
The all-electric sedan offers a choice between two battery options, with a usable capacity of either 107.8kWh or 90kWh – the larger of which holds 26% more power than the EQC’s battery. The EQS will also offer multiple powertrain options. The base model will be the rear-wheel drive (RWD) version, with an option available for a dual-motor, all-wheel drive (AWD), powertrain.
The RWD version is called the EQS 450+ and uses a single 245kW motor. The AWD version, the EQS 580 4MATIC, has a combined power of 385kW from its two motors. Additionally, a performance version of the EQS is to be revealed at a later date. With this power output, the vehicle is capable of a top speed of 131mph (210 km/h), although details on its acceleration speeds have not yet been released.
The lithium-ion batteries themselves have several innovative features. The battery has a built-in DC fast-charging system with a charging capacity of up to 200kW. At DC fast-charging stations, the EQS can reclaim 186 miles (300km) of range in 15 minutes of charging. At home, or a public charging station, the vehicle uses on-board AC charging, and has a charging capacity of 22kW. Users in Japan can benefit from bidirectional charging – giving energy back to the grid as and when needed. The EQS is compatible with several charging functions, including Green Charging, ECO Charging, and Charge Interruption (where charge is suspended at times selected by the user). It is also compatible with Plug & Charge, a function which enables quick charging and payment at select charging points, including those in the Mercedes me Charge network (which has over 200,000 points in Europe, alone). At the launch of the EQS, this functionality will also be operational at points operated by IONITY.
Within the battery cells, the proportion of cobalt has been reduced to ten percent – with an 8:1:1 ratio of nickel, cobalt, and manganese in the optimized active material. The vehicle’s battery management software, which comes as a result of the vehicle’s modular battery concept, allows it to receive over-the-air updates (which can provide updates to the battery management system if needed).
One of the EQS’ most significant features is Navigation with Electric Intelligence – an enhanced navigation experience tailored for EVs. When a user enters their destination, the feature automatically plans the fastest, most convenient, route for them – highlighting charging stations along the way to reduce range anxiety. This plan is based on several factors – including the calculated energy demand of the route and active traffic situations along it. Similarly, the feature dynamically reacts to changes that occur on-route (such as new traffic jams or a change in driving style) based on a combination of data supplied both on-board and from the cloud. Furthermore, users can manually edit the route if needed be – adding or excluding charging stations, for example. The EQS’ battery pack utilizes intelligent thermal management to reduce charging times. This feature is activated alongside Navigation with Electric Intelligence as users navigate to a fast-charging station – allowing for the pack to be preheated, or cooled, to the optimum temperature for fast-charging.
