Shyft's commercial BEV chassis
features customizable length and
wheelbase, enabling it to underpin a
wide range of medium-duty trucks
and end uses.
range of medium-duty trucks and end uses,
including last-mile delivery, mass transit and
recreational vehicles. The company states that
the chassis' modular design will accommodate
multiple weight ratings and classifications, with
a payload of up to 5,000 lb. (2268 kg).
The stripped chassis and delivery van share
an 800-volt propulsion system, which is powered
by a 120-240 kWh battery pack. The
lithium-ion battery packs are liquid-cooled and provide
an approximate range of 150 to 175 miles (241 to
282 km). Shyft states that range can be enhanced
through expanded battery options. This system is capable
of Level 2 and DC fast-charging and can be fully
replenished in two to six hours.
Prototypes of the delivery van and chassis are expected
to reach customers for route testing in the
coming months and will be supported by Shyft's R&D
facility in Plymouth, Michigan. Shyft expects to begin
building the chassis and electric delivery vans at a
plant in the southeastern United States by 2023.
Blue Arc's Power Cube also was announced at the
Work Truck Week show. The Power Cube is a fully portable,
remote-controlled charging station with onboard
energy storage to serve a variety of commercial
charging needs. Shyft states that this charger does not
need to be connected to the grid to function and that
it can have vehicles up and charged in 1-2 hours. The
unit is powered by 500-kWh to 3-mWh lithium-ion
batteries that also can be supplemented with wind
and solar power with panels that track the sun for
maximum exposure. The company plans to debut the
Power Cube in April 2022.

SEA Electric
SEA Electric announced its latest stripped chassis, the SV6 EV, which
it intends to sell in the North American market. The SV6 is a Class 6
BEV chassis powered by the company's SEA-Drive propulsion system,
comprised of a 138-kWh battery powering an AC motor with a
peak output of 335 hp and 1,845 lb-ft (2013 Nm) and an unladen
range of 170 miles (274 km). The system also can be fast-charged at
a rate of up to 100 kW.
" With the SV6 EV, we bring to the market a solution that has been
proven by over a million miles of real-world use, with the package set
to revolutionize the important step-van market across North
America, " said Tony Fairweather, founder and CEO of SEA Electric.
Fairweather emphasized that the design of the SV6 resulted in one
of the lightest and most cost-effective BEVs in the last-mile delivery
segment. Of note is the truck's lack of cooling system for the batteries,
which Fairweather stated was found unnecessary to hit performance
targets.
" We've been able to develop a battery solution and a power system
that enables us to operate from -4 deg. Fahrenheit up to 140-deg
Fahrenheit without the need for any active thermal management, " said
Fairweather. " In engineering out the thermal management, we subsequently
reduced a significant amount of weight, cost and inefficiency.
We still have a radiator mounted in the chassis, but because we're only
