Kenworth Debuts Range-Extended Semi Truck

MAY 2 2018 BY MARK KANE 17

Kenworth presents at the Advanced Clean Transportation (ACT) Expo its latest prototype T680 semi tractor that is capable of driving 30 miles (48 km) on battery power alone.

The truck is equipped with a parallel hybrid electric propulsion system with a lithium-ion battery pack that enables zero-emissions driving.

It’s not known when Kenworth intends to introduce plug-in hybrid or all-electric vehicles on the market, but clearly the time is near.

Kenworth T680 Hybrid Emission Cargo Transport

“The special Kenworth T680 vehicle is part of the Hybrid Emission Cargo Transport (HECT) demonstration project. The HECT project is funded in part by the Office of Energy Efficiency and Renewable Energy (EERE), the U.S. Department of Energy and the South Coast Air Quality Management District.

The T680 HECT truck uses the Cummins Westport ISL G Near Zero (NZ) emission engine fueled by compressed natural gas (CNG), in combination with a generator to extend the truck’s battery range. The truck has a 30-mile zero emissions range using the electricity stored in the lithium-ion batteries. When the batteries are depleted, the near-zero emission engine turns on to generate more energy and extend the truck’s range up to 250 miles.

Kenworth’s partner in developing the truck’s parallel hybrid electric propulsion system is BAE Systems. The system’s energy management and control capabilities ensure that energy generated by the engine and regenerative braking system is appropriately distributed through the dual-rotor electric motor, resulting in lower fuel consumption.”

Stephan Olsen, Kenworth director of product planning said:

“Our near-zero emission hybrid-electric Kenworth T680 has been developed to evaluate potential alternatives to diesel power for commercial vehicles. We believe that in certain applications, such as drayage and regional hauling, the T680 HECT truck will be an excellent solution for local clean air regulations, while delivering performance our customers expect. Later this year, when the truck is placed into service with Total Transportation Services Inc. (TTSI) at the Ports of Los Angeles and Long Beach, we anticipate it will perform equally, or even better than, current diesel trucks.”

Earlier, Kenworth presented its Zero Emission Cargo Transport (ZECT) – T680 prototype with a 100 kWh lithium-ion battery and a hydrogen fuel cell range-extender. The range of ZETC was 150 miles (240 km).

Another govt subsidy for fool cells and the hydrogen hoax I see.

No, You have confused Kenworth’s HECT extended range CNG-powered tractor with their ZECT hydrogen fuel-cell tractor also mentioned at the end of the article.

So is Nikola going to try and sue them also?

Not likely. The claims against Tesla that I’ve read are about the body design. This looks like a conventional truck body on a modified drivetrain.

I’ll admit it. I LOL’ed 🙂

Looks like they are confused about the HECT name. In the press release the ‘E’ stands for “Emission”, but on the truck it is marked as “Electric”. Still a decent idea, however, with a range of only 150 miles it will be relegated to only around town use. Since it would not be fun to have to fill up every few hours on a long road trip.

Ugly. Tesla is going to crush a lot of companies who will be caught flat footed by a superior product combined with a complete charging network. The formula is so freakin’ simple.

Simple formula…but very expensive. Tesla’s semi comes out next year, and they have zero mega chargers built. I think Elon really wants to show investors that Tesla can be profitable, so they will make money in q3 & q4, then back into the red they will go in q1 2019, while they spend like crazy to build a country wide semi charging infrastructure.

If you listened to the earnings call Elon pretty much ignored the semi.What happened to Nikola? They were supposed to announce their monster customer today, right?

My only question is, do they ALSO get free Hydrogen fueling for 3 full years? If they had to pay the REAL cost of the hydrogen to the truck, there would be no takers. Avg Maintenance cost for the California dispensories per the latest information is $16/ kg H2, and thats not including electricity cost nor the basic fuel cost. If they are smart they’ll put a plug on the side of the cab so that the driver at least can go 30 miles economically, with commercially available electricity.

Most of the FCV semis do have plugs, you might as well fill up the battery if you can.Tesla subsidises SCers the government can subsidies H2.

So a private company like Tesla that subsidizes its SCers is equivalent to the govt using our tax dollars to subsidize H2???

And BTW, there are no FCV Semis in production.

Seeing as the price to use a SuperCharger keeps going up, Tesla isn’t subsidizing them much any more. There’s no comparison between them and Hydrogen Infrastructure, since most charging of ev’s – Teslas included – happens at home fully financed by the ev owner.

Meanwhile current H2 drivers either get totally free Hydrogen, or else Hydrogen at 1/3 its unsubsidized cost.

But even getting 2/3rds off the price of hydrogen is still way too expensive for anyone to seriously buy one of these vehicles, as fueling expense is a significant, important cost in the trucking business.

I would think somebody would start to make hydrogen from solar power in sunny states at least. Many years ago we made hydrogen at the university with solar, and constructed a cheap and probably dangerous hydrogen fuel cell car that we used for at least 3 years after that. We did not have high preassure on this, due to it being a super low cost project. Now I have a tiny hydrogen generator at home that I run of a small solar panel, to get “free” hydrogen for projects I work on. Hydrogen generators are of the shelf units. The expensive part is the compression of the gas. With solar getting cheaper and cheaper I would think places with a lot of sun could generate hydrogen at a fair price, or use excess wind power for example. I have seen a facility in Denmark that does that (use wind energy) for testing. They run a converted CASE farm tractor on hydrogen (fuel cell). They have also a battery in this – so you can charge the tractor up, and the fuel cell kicks in as extra power. I think there may be a place for hydrogen fuel cells in the… Read more »

What is missing that only makes it a semi-truck and not a complete truck?

A Capstone Turbine Microturbine.
