Three charging programs are offered in the EQS - 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 programs 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 also has these intelligent charging functions:

  • ECO Charging is a take-it-easy program for 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.
  • The EQS will also allow bidirectional charging in Japan, 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 can be used as a power bank for energy from the home photovoltaic system or supply the household with energy in the event of a public mains failure, for example.

The charging components of the EQS
A latest-generation charging system sits above the rear axle of the EQS. It can be used to charge the battery via the public power grid 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 preliminary check of the installation conditions, a detailed consultation and of course the installation.

A DC box with a charging capacity of up to 200 kW is fitted on board for (fast) charging via direct current. High charging currents can be maintained for a long time through temperature and charging management. Power for up to another 300 kilometres (WLTP) is recharged in just 15 minutes[1].

The actual charging time depends on the battery size, 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 system (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 also have a separate charging socket for DC charging, as will 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 particularly conveniently (for details, see the chapter on Mercedes me Charge).
