The new EQS SUV: the charging functions

Apr 19, 2022

Three charging programmes are offered in the EQS SUV - Standard, Home and Work. In these, parameters such as departure time, air conditioning and maximum charge level can be preset. The Home and Work charging programmes can be activated based on location. This means that they are switched on automatically as soon as the vehicle is parked at a charging point at the positions stored in the system. The user is informed about this in MBUX.

The EQS SUV also has these intelligent charging functions:

  • ECO Charging is a programme for preserving the battery. Various measures reduce the battery load during charging and slow down the natural ageing process of the battery. For example, the maximum charging capacity is reduced, a charging limit of 80 percent is observed and charging is delayed based on the set departure time.
  • With the charging interruptions function, the customer can specify time periods during which the AC charging processes are paused. Electricity costs can be saved as a result, for example.
  • In Japan, bidirectional charging will also be possible with the EQS SUV, i.e. charging in both directions. The CHAdeMO ("Charge de Move") charging standard there supports bidirectional charging. This is the prerequisite for the V2G (Vehicle-to-Grid) and V2H (Vehicle-to-Home) applications. This means that the EQS SUV can, for example, serve as a buffer for electricity from the domestic photovoltaic system or supply the household with energy in the event of a failure of the public mains.

The charging components of the EQS SUV

A latest-generation charging system sits above the rear axle of the EQS SUV. It can be used to charge the battery via the public mains with single-phase or three-phase alternating current and an optional charging capacity of up to 22 kW. In addition, intelligent wallboxes from national partners are available to customers in the individual markets. Mercedes-Benz also offers an installation service for these wallboxes. This includes a pre-check of the installation conditions, a detailed consultation and of course the installation.

A DC fast charging system with a charging capacity of up to 200 kW is fitted on board for (fast) direct current charging. High charging currents can be maintained for a long time through temperature and charging management. Power for up to another 250 kilometres (WLTP) is recharged in just 15 minutes.

The actual charging time depends on the current vehicle parameters, the available infrastructure and the country-specific vehicle equipment. The charging socket is located at the rear right of the vehicle and is designed according to market requirements:

  • Europe and the USA will receive the CCS (Combined Charging System), which allows charging with direct and alternating current via the same connection.
  • The vehicles intended for China (GB/T plug standard) on the other hand will have a separate charging socket for DC charging like Japan (CHAdeMO standard). A twin charging socket is used here; it combines the separate AC and DC charging sockets under one charging flap.

With the new Plug & Charge function, Mercedes me Charge customers can charge the EQS SUV particularly conveniently (for details, see the chapter on Mercedes me Charge).

Mercedes me Eco Coach: The personal trainer for environmentally friendly driving

The Eco Coach supports the use and optimisation of the vehicle on the basis of real data by providing helpful tips and explanations on sustainable and resource-saving use with regard to individual driving, charging and parking activities. This effort is rewarded with points that can be redeemed for attractive prizes at a later date. In addition, exciting challenges can be completed to raise the score further. The Eco Coach is integrated into the displays in the EQS SUV.
