Here's all the charging information Mercedes released for the AMG EQE.


Short charging times through intelligent thermal management

Another advantage of the new battery generation is the short charging times. The energy storage system can charge with up to 170 kW at fast charging stations with direct current. In this case, electricity for 180 kilometres (WLTP) can be recharged in just 15 minutes3. Thanks to the onboard charger, the electrified AMG can be conveniently charged at home or at public charging stations with 11 kW or optionally 22 kW with alternating current. In Japan, bidirectional charging will also be possible, i.e. charging in both directions. In addition, there are intelligent charging programs that can be activated automatically depending on the location. Functions such as battery-saving charging make operations even more efficient.

The efficient thermal management also plays a part in shortening charging times. If Navigation with Electric Intelligence is activated, the battery is preheated or cooled while driving to reach the optimal temperature for fast charging at the charging point. The desired temperature range of the battery is achieved with the aid of the cooling circuit and a PTC (Positive Temperature Coefficient) booster heater integrated into it.

The battery design aims to ensure the optimum battery operating temperature under all operating conditions. The aluminium 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 also stands out for its durability. The ECO Charging function makes a significant contribution to this: the intelligent control reduces the battery load during charging, and thus slows down the natural ageing process of the battery. Customers can also benefit from "charging interruption" function: the charging process can be paused at freely selectable times so as to use cheaper off-peak electricity at a later time, for example. The battery certificate stands for the long service life of the high-voltage batteries. It is valid for up to ten years or up to 250,000 kilometres.
