Depending on your vehicle, you may need an adapter at certain charging stations. This will be flagged in the vehicle’s navigation system under the charging station details. We advise customers use Mercedes-Benz adapters. When using an adapter, always inspect both the adapter and the charger for any damage or debris before connecting. To charge, attach the adapter to the charging cable before plugging into the vehicle. Once charging is completed, remove the adapter from the vehicle before removing from the cable. Please refer to the adapter manual for more information.

Many factors affect charging speed – the battery state of charge, battery temperature, ambient temperature, and station specifications to name a few. EVs generally charge fastest at a low state of charge in moderately warm conditions.
The voltage of the station can also impact the charging speed. Our newest EVs use an advanced 800V architecture. At charging stations that are not 800V capable, the vehicle must decrease the charging speed to accept a charge. This speed varies by model. Consult the vehicle manual for more information.

To help protect the battery and maintain optimal charging performance, EV charging speeds gradually slow as the battery approaches a full charge. At a high-speed charger, charging between 10% and 80% is often the fastest and most efficient portion of the session. Navigation with Electric Intelligence takes this into account when planning a route and will advise you of the target charge level at each stop to reduce total trip time.

Select a charging station in the vehicle’s navigation and start route guidance. The vehicle will prepare the battery to accept the fastest possible charging speed. Plus, at available Mercedes-Benz High-Power Charging stations, your vehicle can reserve a charging stall for you.

Ambient temperature does affect battery range as the battery management system must use energy to maintain an optimal battery temperature, and extreme temperatures place increased demand on the cabin climate control system. To extend range in extreme temperatures, precondition the vehicle while it is plugged in to a power source.

Preconditioning can be initiated on-demand from the Mercedes-Benz app. For added convenience, preconditioning can be scheduled by setting regular departure times either through the Mercedes-Benz app or the vehicle’s center display.

Federal, state, and local incentives are constantly changing. Our EV Savings Calculator can help you find incentives in your area. Consult your local utility provider for additional programs.

The Mercedes-Benz High-Power Charging Network is an ultra-fast DC charging network offering industry-leading speed and reliability. Many stations offer both CCS and NACS chargers, limiting the need for adapters. Plus, new Mercedes-Benz EVs receive two years of complimentary charging at MB HPC stations.^[5] Visit for more information.
