Truck & Off-Highway Engineering - October 2021 - 14

ORIGINAL EQUIPMENT
Hino's Class 8 XL8
prototype employs two
Toyota fuel cells under
the hood, a top unit
and a bottom unit.
assembling the integrated dual fuel cell
modules for use in heavy-duty commercial
trucks. The modules weigh approximately
1,400 lb (635 kg) and can deliver
up to 160 kW of continuous power.
" We're bringing our proven electric
technology to a whole new class of
production vehicles, " said Tetsuo
Ogawa, president and CEO, Toyota
Motor North America. " Heavy-duty
truck manufacturers will be able to buy
a fully integrated and validated fuel
cell electric drive system, allowing
them to offer their customers an emissions-free
option in the Class 8 heavyduty
segment. "
The second-generation Toyota fuelcell
system delivers more than 300
miles (483 km) of range at a full load
weight of 80,000 lb.
" From our Project Z announcement
ecosystem solution that will allow our
customers to seamlessly integrate our
EVs into their fleets and are confident the
eMV will provide an extremely positive
total ownership experience. "
Heavy-duty hydrogen prototype
Hino Trucks announced less than a year
ago that it was building a Class 8 hydrogen
fuel cell electric truck in collaboration
with Toyota. The result of this joint
development was revealed at the ACT
Expo, Hino's first Class 8 XL8 prototype.
" It's amazing what our team has been
able to accomplish in a relative short
period of time. I know our customers
are going to be extremely impressed
with this fuel cell electric truck, " said
Glenn Ellis, Senior Vice President
Customer Experience, Hino Trucks. " We
are looking forward to validating the
performance, reliability and efficiency
of our hydrogen fuel cell electric system
in the XL Series chassis. "
In a pre-event video introduction of
the XL8 FCEV in Ann Arbor, Michigan,
Toyota engineer Jonathan Sander provided
some details of the truck's fuel-cell
(FC) kit. Under the hood where a diesel
engine would typically reside are two
Toyota fuel cells designed specifically for
commercial vehicles, a top unit and a
bottom unit. The prototype has a 12-volt
battery system with shutoff similar to a
14 October 2021
diesel truck, plus a high-voltage battery
that works with the fuel cells to provide
comparable power to a traditional Class
8 truck. The hydrogen tanks are inside a
cabinet behind the cab. At the rear center
of the vehicle is a two-motor system
and transmission and a prop shaft leading
to the rear differential. Torque output
also is comparable to a Class 8 over-theroad,
80,000-lb application, Ellis said.
Toyota announced in August that
starting in 2023, a dedicated line at
Toyota Motor Manufacturing Kentucky
in Georgetown, Kentucky, will begin
last October, we have received significant
interest from customers and now
we have something tangible to show
them in our prototype FCEV, " said Bob
Petz, senior vice president of vehicle
and parts sales, Hino Trucks.
Next-gen electric trucks
BYD unveiled two battery-electric heavyduty
trucks, the Gen3 8TT and 6F, that
feature cabs styled by Wolfgang Josef
Egger, the renowned former Audi chief
designer. The cabs offer improved aerodynamics
and energy efficiency. The
Starting in 2023,
a dedicated line
at Toyota Motor
Manufacturing
Kentucky
will begin
assembling
integrated
dual fuel cell
modules for use
in heavy-duty
commercial
trucks.
