Check Drive: The electrical Volvo VNR
The electrical truck is carving out a distinct segment in stop-and-start and low-mileage purposes, so sending a small fleet of them into California’s ports appears like no-brainer.
Introduced simply greater than a 12 months in the past, the Low Influence Inexperienced Heavy Transport Answer (LIGHTS) partnership teamed collectively Volvo Vans North America (VTNA) fleet clients NFI and Reliable Freeway Specific (DHE) within the deployment of electrical VNR vans to be used at their California port operations – a part of a joint effort to exhibit the power of battery electrical automobiles (EVs) to enhance freight and warehouse efficiencies, scale back emissions and enhance air high quality.
The primary crop of LIGHTS vans have been ordered and delivered, however supply of 1 straight truck particularly might have been a bit of delayed as a result of, final week, I used to be driving it across the Auto Membership Speedway in Fontana, California.
My take a look at unit, one of many first 5 models to be constructed, belonged to DHE and is a part of Volvo’s LIGHTS partnership, which can see a mixture of straight-trucks and tractors service devoted routes in and round California’s Inland Empire. The variety of eVNRs is predicted to swell to greater than 20 by the challenge’s finish and convey together with them an array of electrical help gear, like forklifts and pickups, private and non-private charging infrastructure and dealership-based electrical truck service and upkeep capabilities.
The primary 5 vans have been constructed on the road at Volvo’s New River Valley (NRV) truck meeting plant as a glider earlier than being completed by hand in Greensboro, N.C. When the vans enter manufacturing late this 12 months, the electrical VNR will likely be in-built NRV on the identical line as typical VNR fashions however its electrical driveline will likely be put in on a special manufacturing line.
The electrical VNR’s driveline is time-tested, having began on Volvo’s electrical bus (Volvo has offered greater than 4,000 electrified buses since 2010). It was then built-in into Volvo’s European FE electrical cabover earlier than making its method to the VNR.
The truck’s radiator is useful and retains the system heated and cooled, which helps battery life. A modular energy field – mainly the mind of the entire outfit – sits the place a diesel engine would usually. Packs of batteries flank the cab, every weighing about 1,150 kilos, and provide onboard energy. The battery system is designed like a shelf, permitting packs to be slid out and in for service.
The charging port is positioned on the motive force’s aspect, which prevents the motive force from unknowingly pulling away whereas the truck is charging. You’d virtually must climb over the cable to get into the cab.
The eVNR options center-mounted twin electrical motors with a two-speed gearbox. The truck seamlessly shifts into second gear round 30 mph. It doesn’t take off like a rocket – nor ought to it – however the torque and energy are prompt.
The electrical truck might at some point revolutionize the transportation business, however little or no of what issues to the motive force is slated to get an overhaul. So far as the driving expertise, there’s no horny story to inform. It feels, handles and drives like a truck, which is an efficient factor. Of all of the obstacles to beat – lack of infrastructure, vary anxiousness and battery weight and price – reinventing on-road really feel and efficiency is an pointless warfare to struggle.
Gear selector buttons – impartial, drive and reverse – are mounted within the sprint. To maneuver the truck ahead, you launch the air brake, hit the D button and punch the throttle. There’s no creeping alongside at idle, so hitting the pedal is fairly essential.
The quantity of noise coming from the truck – at the least the absence of it – feels … odd. A whole lot of engineering has gone into a contemporary diesel engine to restrict the quantity of noise it makes, however there’s no mistaking a diesel-powered Volvo VNR for a Tesla Mannequin 3 in a blind take a look at. The one noise coming from the electrical truck, apart from the tires making contact with the pavement, comes from the air compressor.
By putting the truck in reverse, the truck’s electrical motors flip within the different route. There isn’t any “shifting” into reverse. That makes the change in course a lot smoother and simpler on the cargo.
A gauge the place the tachometer would usually be tells you the quantity of load on the battery. At relaxation, it factors to zero. Relying on pace, grade and cargo, it’ll drift to a point of unfavourable.
Coasting downhill, for instance, with the regenerative brake engaged will pump extra energy into the battery and push the needle towards the plus aspect, as you’re making extra vitality than you’re utilizing.
The regen brake is positioned on the stalk the place the engine brake could be, and equally has three phases. Every will have interaction after about 2 seconds of the motive force having taken their foot off the accelerator. An computerized setting takes into consideration the truck’s payload and focused vary to seize essentially the most quantity of vitality wanted within the smoothest stage attainable.
Volvo will use the LIGHTS challenge to assist decide simply how far its electrified VNRs can journey on a full cost underneath load, however the vary demand on these routes is fairly minimal – typically lower than 175 miles.
Volvo has logged about 2,000 take a look at miles throughout the primary 5 vans however they’re about to be handed over full time. These vans aren’t expertise demonstrators. They’re working vans. They’ve actual freight shifting obligations and downtime will likely be an issue.
And that’s precisely how VTNA President Peter Voorhoeve desires it. LIGHTS isn’t a science experiment and Voorhoeve hopes it’ll pave the way in which for a greener, emissions-free electrified future the place electrical vans at a port will likely be as ubiquitous as Maersk containers.
“I wish to capable of say that this LIGHTS challenge actually modified using electromobility,” Voorhoeve stated, noting he has the next goal to the challenge than merely getting orders. “I hope to promote as lots of them as attainable, however that is bigger than promoting vans. That is about shifting the general public opinion that this works. That that is the way in which ahead. If we get that, then LIGHTS was a hit.”
