Cost of charging and autonomy on a long journey of 850 km

Mercedes’ foray into the electric world continues, and today we’re taking a look at the Mercedes EQE electric sedan under the hood. More specifically, we’ll focus on his ability to carve a path using our extensive reference routes.

Electric sedans had a great year in 2022, with plenty of premium models. In addition to the Tesla Model 3 and Model S, we come across several German models in particular: the BMW i4, the Porsche Taycan or the Mercedes EQE, which we will return to in this file.

While everyday life is no problem for an electric car as long as you have a charging solution, long trips that exceed the car’s range require a bit of organization. So we’ll put the Mercedes EQE through its paces using two benchmark routes planned via A Better Route Planner.

As always, the rules are: the start takes place with 100% battery, the finish is 20% and the car must run at the limit speed. After recalling the features of the Mercedes EQE, we will examine the various journeys in detail in terms of duration, number of payments and associated costs. Below, you’ll find summary tables that will quickly show the differences between each car.

Features of Mercedes EQE

Mercedes EQE 300 is one of the electric cars that offer the most autonomy. Indeed, in the WLTP mixed period, Mercedes announces autonomy of up to 639 kilometers. Its 89kWh battery and fast charging capability (170kW peak) is a big plus in our training.

To charge the battery to 80% in about thirty minutes, we use the different charging networks currently available in France: Ionity, Fastned, Allego or Tesla Superchargers, which are open to all. For simplification reasons, we consider the average price of fast charging to be 0.68 euros per kilowatt hour. However, please note that some payments may be more expensive or even cheaper using different subscriptions or payment cards.

As always, A Better Route Planner is used to plan journeys with the default consumption reference for the Mercedes EQE 300.

Route planning

Keeping all vehicles under equal conditions, We start trips with 100% battery, given that you have to pay for this top-up at the average price per kWh in France, currently €0.17. 89 kWh means that 15 euros : we take into account this cost in addition to the fast payment during the balance sheet for each long trip.

The first big trip will simulate a summer vacation from Orleans to Arcachon (530 kilometers). The winter route will start in Caen and end in Chamonix-Mont-Blanc (850 kilometers).

The parameters shown in the Better Route Planner for a summer route are: 25 degrees Celsius outside temperature, no wind, reach a charging station with 10% battery remaining, and reach a destination with 20%. For a winter trip, 0 degrees Celsius is essentially the same except for the weather we choose.

Balance of different routes

530 kilometers twenty minutes charge

With a WLTP range of more than 600 kilometers, a trip of 530 kilometers, as we chose, does not pose any particular problems. However, Arcachon really needs a charge to arrive at 20% battery.

23 minutes on Ionity for €28and here the Mercedes EQE is about 80%, which is enough to reach the destination without incident.

With only 70% battery, A Better Route Planner estimates thatIt is possible to travel with a Mercedes EQE car at a speed of 280 kilometers, this is remarkable. Estimated fuel consumption for this trip is around 203 Wh/km, which corresponds to a 430 kilometers of autonomy with 100% battery.

The total journey time is 4 hours 51 minutes, or an average of about 110 km/h with cargo.

Three small loads and then go

When winter comes, electric cars no longer have the same performance. Conditions are difficult for many cars, whether in terms of increased consumption or non-optimized fast charging as in the summer.

Mercedes EQE is slightly affected by 0 degree temperature and positive slope because A Better Route Planner offers only three payments (14, 24 and 31 minutes) for the 850 kilometer route..

The course uses three different networks: Fastned, Tesla and Allego, it shows The variety of fast charging networks is of great interest to the end customer. Indeed, he can stop where he wants according to his needs and preferences. The costs associated with these three payments are estimated at €97 and, with the addition of the fare from home, the price of this trip is estimated at 112 euros.

Consumption on the side is listed at 240 Wh/km, which gives us a 370 kilometers of autonomy in winter conditions for Mercedes EQE. This fits roughly 20% less than the milder conditions of summer travel.

Consumption, charging cost and range

Mercedes EQE is comfortable on long trips

With a WLTP range of over 600 kilometers, It’s no surprise to see the Mercedes EQE shine in this long-distance exercise. Indeed, it manages to cover itself almost as well in summer as in winter It should be filled for the first time after 300 kilometers. In terms of costs, the summer route is shown at 8 euros per 100 kilometers, and the winter route at 13.20 euros per 100 kilometers..

This corresponds to a respectively A thermal car that consumes about 4.50-7.30 liters per 100 kilometers. Given the range in which the Mercedes EQE is placed, an equivalent thermal car is likely to be significantly more expensive, even on long journeys. Because on a daily basis, there is no possible comparison The Mercedes EQE easily shows a cost of around two euros per 100 kilometers by charging at home during peak hours..

In addition to the thermal car comparison, this exercise allows you to see where the Mercedes EQE stands against its direct competitors. In addition to taking longer to charge, the BMW i4 costs about 30% more over two long journeys. The same goes for, for example, the Porsche Taycan, which can only hold its own against the Tesla Model S and Model 3 EQE.

Despite this, Cars from Elon Musk’s company cannot offer equivalent luxury services : sound insulation, flexibility of the suspensions or the quality of the interior are undeniably the advantages of the Mercedes EQE. For those who put this in the forefront, there is no doubt that a few tens of euros to pay more during long journeys will not be a decisive factor in the choice of car.
