Electric FAQs

Depending on the vehicle's equipment, ECO Assist analyzes the expected route data. This allows the system to optimally adjust the driving style for the route ahead, using minimal energy and recuperating as much as possible.

If the system detects an event or vehicle ahead, ECO Assist will calculate an optimized speed based on the distance and available route information.

In this case, releasing the accelerator pedal will activate Override Mode via intelligent recuperation. If ECO Assist detects a vehicle traveling in front or a stationary vehicle ahead, it can apply the brake to bring your vehicle to a standstill. For example, at the end of a traffic jam or if a detected vehicle ahead stops in front of you.

If the deceleration provided by ECO Assist is not sufficient, you must also brake with the service brake. For example, if you begin to accelerate in slow-moving traffic and the distance to the vehicle in front is very short.

Depending on the vehicle equipment and at low speeds (e.g., in a parking garage or on play streets), no adjustment will be made for stationary vehicles and therefore no display will appear.

The three levels indicate different charging speeds, measured in kilowatts (kW), accessible via home chargers or public charging stations.

Level 1

This method uses a standard household outlet that connects using the Mobile Flex Charging cable provided with every all-electric Mercedes-Benz vehicle. This level charges your vehicle at a rate of around 2-4 miles per hour on a 110V circuit. Due to the very limited power output, we do not recommend relying on this method to charge your Mercedes-Benz EV.

Level 2

This method is available for both home and public charging. For charging at home, a wallbox on a dedicated circuit is required. Your dealer can assist with purchasing and arranging installation. As a home charging solution, Level 2 is capable of charging at a rate of around 20-30 miles per hour on a 240V circuit. At a maximum of 9.6 kW, the EQS can charge from 10 – 100% in just over 11 hours.

Level 3

This is called DC Fast Charging, and it is the fastest method of charging with a growing number of public stations available nationwide. The amount of electricity required, and cost of installation makes Level 3 DC Fast Charging impractical for home use. However, DC Fast Charging can be found along highways, in shopping centers and more, making long road trips possible for EVs.

When the Plan Charging Stops route option is enabled, the optimal route based on time is calculated along with the required charging stations.

The charging stops along your route are determined by the route and charging times needed. They are then set as destinations.

Navigation with Electric Intelligence constantly checks numerous influencing variables, such as the vehicle’s interior climate control or changes in the weather. For each section of the route, the current energy requirement is calculated from the high-voltage battery.

The multimedia system determines the ideal charging stations along the route based on availability and charging capacity.

For each charging stop, the required amount of energy and the expected charging time is calculated and displayed.

If the driver wishes, they can receive a mobile phone notification when the required condition of charge is reached.

The high-voltage battery will continue to charge until the process is interrupted by the driver.

You can modify the route calculated by the Navigation with Electric Intelligence. The options “Ignore Charging Station” and “Add Charging Station” are available for this purpose.

There is. For more details, see your certified tax professional or read about the new credits available under the Inflation Reduction Act, passed in 2022.

Many states offer their own incentives, including rebates and other non-monetary incentives like unlimited access to the HOV lane, which saves you time in traffic. To see your state's incentives, visit www.afdc.energy.gov/laws/state.

Yes, but it's much cheaper. Electricity in the United States purchased for your home through your utility is typically around 12 cents per kWh. If you drive 15,000 miles a year, that's about $540. A year of gas, on the other hand, can cost around $1,400. On top of that, the price of gasoline can fluctuate wildly, whereas the price of electricity is relatively stable. To see the average price of electricity in your state, visit the website for the Energy Information Administration. All new Mercedes-Benz EV customers also get 2 years of free, unlimited 30-minute charging sessions through Electrify America. This enables cross-country travel essentially for free.

Charging sessions can be initiated in multiple ways. First, your dealer will make sure your vehicle is activated with Mercedes me Charge. Upon activation, your vehicle will be ready to initiate charging sessions with Plug & Charge, activation through the RFID card, or remote activation through the MMC app, or remote activation through the vehicle’s navigation system. Electrify America stations support Plug & Charge, which is the most convenient and secure way to initiate charging sessions. Simply plug in the activated vehicle and charging will begin automatically. For more information about this and other methods, please visit https://www.mbusa.com/en/charge/on-the-go.

Regenerative braking adds to your charge as you drive. When the vehicle is coasting and the driver touches the brake pedal, the electric motor acts as a generator, slowing the car and pumping electric power back into the battery. Essentially, the momentum of the car is converted into extra power, extending your range as you go. 

You might have heard of three levels of charging electric vehicles: Level 1, Level 2 and Level 3 DC fast charging. Here's what they mean:

• Level 1 charging: This is charging that takes place on a typical electric outlet.
• Level 2 charging: This level of charging utilizes a wallbox that’s connected to a 240-volt outlet. Away from home, most public charging stations are Level 2. Some are free, while others require a paid membership. This is the most common type of charging for electric vehicles.
• Level 3 DC Fast Charging: This is the fastest kind of charging currently available, with a growing number of stations available publicly. The amount of electricity they require, and cost of installation, makes them impractical for home use. DC Fast Charging can also be found along highways, making long road trips possible for EVs

There are over 65,000 charging stations throughout the United States, with more being added practically every day. The best way to find them is with Mercedes me Charge, our charging ecosystem. Mercedes me Charge integrates multiple charging networks into one, giving you more freedom and flexibility. You can view all available places to charge in the Mercedes me Connect app or even in the headunit of your Mercedes-EQ vehicle.

Yes, but it's worth noting that a standard household outlet is a 110V outlet which is far less powerful than a 240V outlet, which is typically found with dryers or can be installed by a licensed electrician. The good news is that having a 240V charging station installed in your home is easy. The ChargePoint Home Flex is the wallbox we’d recommend. Please go to their website to purchase one. In addition, we recommend using Qmerit for installation.

Every Mercedes-Benz electric vehicle has specific features to ensure safe charging. Instead of the electricity flowing as soon as it's plugged in, like a traditional appliance, the vehicle and wallbox converse to make sure it's safe before any electricity flows. Special attention has also been paid to make sure you can safely charge in wet weather.

No. While many electronics benefit from an occasionally empty battery, the lithium-ion battery has no "memory effect," meaning they never have to be drained, nor do they have to be fully-charged. The life of the battery remains unaffected.

Lithium-ion batteries are known for being lightweight, quick to charge, and having a long service life, which makes them perfect for electric cars. Our lithium-ion batteries are automotive grade batteries, unlike the ones that are in our mobile phones, laptops, and other devices, they are engineered for longevity.

No, careful attention is paid by our engineers to ensure that a Mercedes-Benz EQ vehicle meets our high standards of safety. The battery pack is sealed, and high-voltage circuits are protected from casual contact and appropriately marked so you know where they're located. All high voltage cables and circuits are also marked and are in bright orange with warning labels on them.

The same high safety standards that define Mercedes-Benz cars apply to our electric vehicles. The batteries are all safely protected in the event of an accident, and depending on the severity of the accident, the high voltage system is automatically disconnected in fractions of a second.

Just as you would with a gas-powered vehicle, you'll need to take extra steps during long term storage. Instructions can be found in the operator's manual.

Since the battery used in our electric vehicles is automotive- grade, it's extremely durable and engineered for longevity and reliability. Very rarely does a battery need to be replaced during the average ownership period.

In many ways, you'll notice an improvement. Unlike gas cars, electric cars deliver power to your wheels instantly, with no lag time, as soon as you step on the pedal. The result is greater torque and acceleration. They're also exceptionally smooth. There's no gear shift and no shaking when idle. Most drivers are so accustomed to the constant vibration of gas vehicles that it isn't until they experience electric that they realize the remarkable difference.

MPGe is the efficiency number to provide an equivalent to the traditional miles per gallon. Essentially, it's how manufacturers show the efficiency of a vehicle: The higher the MPGe, the more efficient it is. The other way to measure efficiency with an electric vehicle is through Watt-hours (Wh)/mile or kilowatt-hours (kWh)/100 miles. The lower the number here, the better.
