Daimler & Amazon Are Testing Electrical Lengthy-Haul Vans In Germany

One of many robust issues about designing any sort of machine is that the actual world is usually a little extra punishing than the maths. It’s not that math isn’t an excellent device for determining how issues work in the actual world, however that it’s simple for people to not know what they missed when doing the maths and operating laptop simulations. The factor about the actual world is that you simply’ll work out fairly rapidly in the event you didn’t account for one thing.

Desire a loopy instance of this? Right here’s a brief YouTube video exhibiting what occurs when the actual world lets that you simply didn’t get the maths proper.

On this case, the stunt’s planners received a cable that was sturdy sufficient for the mixed weight of the individuals who have been going to swing from the bridge. However, they forgot concerning the G forces that occur when swinging, which multiply the quantity of power that the cable wants to resist. After they swung, the cable broke, and the daredevils have been despatched plummeting into the water that was far under. Fortunately, none of them died, however a number of of them sustained extreme accidents.

Daimler & Mercedes Gained’t Make This Mistake

Even probably the most expert and proficient engineers know that the job isn’t finished till you’ve received suggestions from real-world testing, and people working for Daimler Truck are not any exception. They designed a very nice electrical long-haul truck, however now it’s time to ship the prototypes into hurt’s solution to see how they will take the actual world.

On a single cost, the Mercedes-Benz eActros LongHaul could have a spread of 500 kilometers and may obtain megawatt charging. In September in Hanover, Mercedes-Benz Vans will debut a “prototype prototype” of the eActros LongHaul as the primary attraction at this yr’s IAA Transportation present.

“As with all our e-trucks, we are going to depend on early sensible assessments with prospects for our eActros LongHaul,” mentioned Michael Scheib, Head of Product Administration, Mercedes-Benz Vans. “By doing so our engineers will be capable of incorporate beneficial information gained from real-world operations – particularly with regard to high-performance charging – immediately into the event of the series-production automobile. We’re very happy with the deliberate partnerships with Amazon and Rhenus.”

Amazon and Rhenus are planning to check the eActros LongHaul as a part of a brand new venture known as “Excessive efficiency charging for long-haul trucking” (aka “HoLa”). HoLa is a analysis venture that goals to develop, function, and research a high-performance charging infrastructure for battery-powered lengthy distance transportation. Along with Daimler Truck, different firms and analysis establishments are concerned on this venture.

To energy the vans, CCS charging stations might be arrange at a number of spots on the A2 between Berlin and North Rhine-Westphalia initially. Because the venture continues, deliberate websites might be geared up with megawatt charging station (MCS) charging stations that assist the brand new MCS charging commonplace as a member of CharIN — the worldwide affiliation for standardizing charging infrastructure. Daimler Truck is actively concerned in CharIN’s improvement of a brand new MCS charging specification, serving as an lively participant inside CharIN.

The HoLa charging factors might be positioned alongside the A2 at a number of websites. These are distributed throughout each motorways and logistics facilities. Consequently, the system could also be examined beneath real-world circumstances, in addition to acquiring real person expertise. The fast charging of battery electrical automobiles is one space of testing: battery-powered automobiles ought to be capable of cost quick sufficient that they will full the 45-minute statutory break interval.

Why They’re Doing This As an alternative Of Skipping To Truck Gross sales

Clients might be accompanied by a staff from Mercedes-Benz Vans to make sure their satisfaction all through the venture. The drivers of the e-truck might be educated in methods to function the automobile and charging system extensively. Drivers’ feedback might be recorded throughout common interviews and questionnaires, which might be compiled and evaluated for future prototype improvement and charging expertise enchancment.

By putting in measuring gadgets within the e-trucks, they’re able to gather knowledge factors whereas these automobiles drive. These transmitted knowledge units will then be evaluated by Mercedes-Benz Vans earlier than sharing chosen data with their partnering analysis establishments.

It’s this knowledge assortment that makes the distinction in not solely finalizing designs (to repair no matter isn’t working nice), but in addition for adequate information to promote and assist future mass manufacturing.

Dealing with Some Critical Juice

The eActros LongHaul makes use of batteries with lithium-iron phosphate cell expertise (LFP). These are most notably characterised by their lengthy service life and better usable power. At a charging station with an output of 1 megawatt, the batteries might be charged from 20 to 80% in beneath half-hour. The truck’s lengthy vary on a single cost, mixed with megawatt charging, leads to total ranges that match these of standard vans — enabling two-shift operations.

The eActros LongHaul, in keeping with Mercedes-Benz and Daimler, delivers a very well-balanced driveline for an excellent driving expertise. As well as, the eActros LongHaul comes commonplace with quite a lot of security options supplied by the producer. The idea behind the Mercedes-Benz Vans battery-electric long-distance transport is to offer prospects with a complete bundle that features automobile expertise, consulting, charging infrastructure and providers. Clients ought to select the eActros LongHaul as a result of it’s economically viable, environmentally accountable, and dependable.

Wait, What? A Megawatt!?

Instantly, it’s fairly clear that we’re coping with plenty of energy, each for batteries to retailer, for motors to make use of, and for the truck to maneuver to the wheels. It’s fairly clear why Mercedes and Daimler want to check these in the actual world to ensure they aren’t breaking or having electrical issues.

On the identical time, although, it’s not an otherworldly determine. A Tesla Semi can generally be seen charging utilizing 4 Supercharger stalls, which produce 250 kW. That’s a megawatt, in whole. So, we’re speaking concerning the power wanted to fast cost 4 vehicles, which is fairly small when you think about {that a} semi-truck can weigh as a lot as 15-20 vehicles.

Both means, this will likely give us a clue as to why different long-haul electrical vans aren’t on the market and on the highway with prospects but. The event course of must iron out the entire kinks earlier than severe enterprise operations can rely upon them.
