Behind the wheel of an eActros – interview with TruckTrainer Jean‑Luc Merck

Interview

Have a nice drive!

Strong torque from the word go, more peace and quiet in the cab – the eActros makes driving even more effortless and stress-free. TruckTrainer Jean‑Luc Merck gives some tips for getting started with electric driving.

Jean‑Luc Merck, everything is in place, and the new eActros is ready. So, is it now time to get in and drive off?

Well, the driver first gets all the help they need for the new drive. This includes learning a little about the high-voltage technology, taking a look around the eActros and checking out the inside of the cab. Theory is then followed by practice with an initial drive, where we accompany the driver, give them some tips and answer any questions they have.



How big are the changes in the cockpit?

The new drive means that some new features are required, but it’s all very manageable. On the main display, for example, the eActros has a power meter instead of a rev counter. When the engine needs impetus, the power meter will display the power consumption. However, when the eActros is rolling or braking, the electric motors can be used as power generators. The power meter then shows how much energy has been gained during this recovery process.

Instead of the fuel gauge, there is now a battery charge indicator, which also includes range information. And if required, a menu showing the charging settings can be accessed on the secondary display.

“I can recover energy by using the continuous brake.”

What’s important when it comes to charging?

As the routes are always planned out, charging can also be well prepared. So, what I need to know is: How many kilometres are to be covered? What uphill and, in particular, downhill stretches are along the route? “Filling up” is never necessary, as I can recover energy by using the continuous brake. The vehicle’s kinetic energy is converted into electrical energy and supplied back to the batteries. This can also be precisely regulated through the five levels of the continuous brake. Also, by not charging the batteries up to 100 per cent every day, you can extend their service life. This is just the same as with smartphones.

Does the driving experience feel any different?

Driving feels even more pleasant. The noise level is much lower than in the case of a combustion engine, and interruption to power delivery is far more rare since the eActros only has two gears. Thanks to the installation of the battery packs under the chassis, the eActros also has excellent road holding. Anticipatory driving is also very important, as well as making optimum use of the continuous brake to ensure maximum energy recovery.


The plug can only be removed when the vehicle is unlocked and the safety button is pressed.


How safe are the high-voltage batteries?

We have taken all possible safety precautions. These include the battery management system, temperature monitoring, crash sensors and permanent insulation testing, to name but a few.

Everything about the eActros is designed to make the use of high-voltage technology as practical and safe as possible. For drivers, this means: get on board and enjoy the new driving experience!
