cost of charging and autonomy over a long journey of 850 km


Can the Renault Mégane E-Tech be the main vehicle of a household? This is the question we will try to answer in this dossier, which will be put to the test in both summer and winter during our main reference trips. Let’s see where the Renault Mégane E-Tech stands compared to the others.

An electric vehicle is very suitable for the daily life of those who have a home charging solution, which allows them to drive cheaply and without restrictions. If this description indeed applies to the vast majority of journeys, it no longer applies to long journeys that exceed the car’s theoretical range.

That’s why we started this series of files on different connected cars, to put them to the test during our reference trips. The Renault Mégane E-Tech will have to do a lot to place itself among the vehicles that have already been examined, such as the Kia EV6 58 kWh, the Tesla Model Y Propulsion or the MG MG4.

As usual, the rules are as follows: the start is at 100% battery, the finish at 20%, and the vehicle must be driven at the limit speeds. We remember the characteristics of the vehicle (autonomy, battery, payload) and compare them with the reality on the ground. Let’s see what the Renault Mégane E-Tech has in store for us on long journeys!

The characteristics of the Renault Megane E-Tech EV60

We select for this file the Renault Mégane E-Tech EV60, which is therefore equipped with a 60 kWh battery, with a WLTP range of 450 to 470 kilometers, depending on the configuration. We also have a buying guide to help you see more clearly across the range.

The maximum permitted charging power is 130 kW and a charge of 10 to 80% is announced by Renault at 37 minutes in ideal conditions. Thanks to the CCS Combo port of the Mégane E-Tech, it can navigate through all the fast charging networks available, such as Ionity, Fastned, Totalenergies or the Tesla Superchargers accessible to everyone.

As always, we rely on the simulations of the excellent A Better Route Planner, which will be used to plan the routes, with the standard reference consumption inherent in the Renault Mégane E-Tech EV60.

Route planning

To respect the rules of this exercise, we start traveling at 100% battery, since you have to pay for this filling at the average price per kWh in France, currently 0.17 euros. The 60 kWh then represent €10.20which must be added to the balance for each long journey.

The first major route corresponds to the summer holiday from Orléans to Arcachon (530 km), while the winter route starts in Caen and ends in Chamonix-Mont-Blanc (850 km).

For the summer route, the parameters indicated in Een Betere Routeplanner are as follows: 25 degrees Celsius outside temperature, no wind, arrival at a charging station with 10% battery charge and arrival at destination 20%. For the winter trip, it’s essentially the same, apart from the weather, where we’ve chosen a temperature of 0 degrees Celsius.

The balance of the different routes

Charging for almost an hour for 530 kilometers

During this great summer journey that connects Orléans to Arcachon, two charging stops are required. The first is performed after 222 kilometers covered, for 38 minutes on the Poitiers Supercharger. At the current rate of €0.79/kWh for non-Tesla subscribers, this rate will cost €36.50.

The second charge is on the Ionity network, this time for 18 minutes and costs 20 euros. In total, the charging time is 56 minutes, for a price of 56.50 euros. By adding the cost of charging at home, this journey of 530 kilometers therefore costs 66.70 euros. The estimated consumption is 219 Wh/km, which corresponds to a range of about 275 kilometers.

Charge for 30 minutes every 150 kilometers in winter

The winter reference route we use poses many challenges for electric vehicles. It combines three factors that have a major impact on range: temperature, speed and altitude gain. Thereby, don’t imagine getting anywhere near WLTP autonomy cars we consider on this route between Caen and Chamonix-Mont-Blanc with 0 degrees: it’s impossible.

With the Renault Mégane E-Tech EV60, the greatest distance traveled between two charges is 166 kilometers on this reference path. It takes five charging stops to arrive at the destination with a battery of 20%, and total charging time is two hours and twelve minutes.

However, due to the different charging networks used, this journey can be made without any problems, as the density of fast chargers available is quite high. Tesla, Ionity, and even Kallista Energy are on the track, making this trip doable if we accept the load restrictions.

A free charging station is currently available in Sauvigny-le-Bois, and there are other charging stations nearby, including the Tesla Supercharger in Avallon, if this station is not available. In total, the costs related to fast charging vary between 93 and 129 euros, which is a total price of the trip including departure tax between 104 and 139 euros for 850 kilometers. Finally, the estimated consumption is 257 Wh/km, which corresponds to an average range of 230 kilometers on a full charge in these conditions.

Consumption, charging costs and range

We summarize the costs and charging times (including home charging at EUR 10.20) in the table below. As we go through our examples, you can see where the vehicle you’re interested in is in relation to the other vehicles on a similar trip.

Is the Renault Mégane e-tech suitable for long journeys?

As you can see, the Renault Mégane E-Tech is quite capable of cutting the road, but you have to accept both frequent and long charging. Indeed, with almost an hour’s charge before the summer holidays, it’s at the bottom of the table, behind the MG4, which is much cheaper.

Naturally, it’s not a few extra minutes of charging that will help you make a decision about a particular electric car, but it’s interesting to see where the Megane E-Tech stands among the rest. And it is clear that she is not one of the good students.

In terms of travel expenses, with 12.65 euros per 100 kilometers for the summer ride and 16.35 euros per 100 kilometers for the winter ride, traveling in a Renault Mégane E-Tech at current rates remains relatively expensive compared to other electric vehicles.

ICONIC VERSION – RAFALE GREY

Consumption is indeed flying off at high speed, making it mandatory to top up approximately every 150 kilometers, which does not allow to keep costs low enough over long distances. Some optimization options may appeal to heavy rollers, such as the Ionity Passport subscription or membership for $12.99 per month with Tesla. In the first case, the obligation is annual, but with Tesla there is no obligation, and the subscription is reimbursed by the savings of charging, as soon as more than 100 kWh have been charged on the Superchargers accessible to everyone.

In conclusion, we have to admit that even if the Renault Mégane E-Tech has many advantages, long journeys are not its strong point. Compared to vehicles that offer comparable autonomy on paper, it does less well in this exercise: the Tesla Model Y Propulsion or the Hyundai Ioniq 5 indeed make it possible to arrive at your destination faster. Finally, the MG4, which is significantly cheaper, loses only 11 minutes on the winter route and is equal on the summer route. It remains to be seen whether these lost minutes on long journeys are decisive for you or not.

Is buying an electric car still worth the cost and effort?

Wouldn’t it already be “too late” to buy an electric car? Indeed, prices are only rising, fast charging is becoming very expensive and the availability of public charging infrastructure is struggling to…
