BAE System’s
HybriDrive parallel propulsion system for heavy-duty vocational trucks
features a modular design so as not to affect chassis layout. The new
parallel system benefits from the company’s proven series hybrid in
terms of software, control laws, and energy management, helping to
accelerate market-readiness.
For fleets, going green is a high priority—but making green is an even higher one.
“There is a significant uptick in the
cost [for electric vehicles]. At the end of the day, we are a for-profit
business, and we need to make the bottom line work,” said Steve
Saltzgiver, Group Director of Fleet Operations, Coca-Cola Refreshments, Inc., discussing his company’s partnership with Missouri-based Smith Electric Vehicles at last month’s Green Truck Summit in Indianapolis.
Coca-Cola and other large fleet operators such as Staples, FedEx, and Frito-Lay
are in the process of crunching the numbers to determine if electrified
vehicles make sense in their fleets—and if so, where exactly. “They are
not one-size-fits-all,” Saltzgiver noted. “You want to make sure it’s
in the correct application...and you need to understand the [EV]
limitations.”
The correct application is “almost any
truck” used in an urban environment, according to a recent study
conducted by researchers at MIT’s Center
for Transportation and Logistics. They found that the operational costs
for electric delivery trucks used on a daily basis within cities can be
9-12% lower than with diesel-powered trucks.
Return on investment (ROI) was a hot
topic at this year’s Green Truck Summit, whether experts were discussing
the electrification of vehicles, retrofitting of propane autogas
systems, or other technologies. And eventually—if not now—ROI must be
realized without government assistance.
“The goal again is to produce biofuel
without subsidy…Electric vehicles, without subsidies. We’re talking,
‘This is the best technology; don’t need any help,’” said Dr. Steven
Chu, U.S. Secretary of Energy, during his keynote address that kicked
off the Summit. “Whether it’s going to be 5 or 10 or 15 years from
today, I don’t know, but it’s around the corner.”
According to Mark Greer, Green Fleet Market Manager for Altec Industries,
it can be difficult to monetize all of the benefits that contribute to
payback, such as the environmental stewardship gained by operating a
green fleet. But the main “hard benefit,” he noted, is savings in fuel
costs, particularly as diesel prices climb.
Reduced maintenance can be another
benefit. Longer brake life was one example cited by several experts.
According to Scott Carson, National Sales Director for Smith Electric
Vehicles, one customer discovered that the brakes lasted five times
longer on the EV compared to its conventional diesel-powered trucks,
positively impacting the payback equation.
BAE Systems
discovered through customer research that the “payback requirement” for
heavy-duty hybrid vocational trucks is less than five years. According
to Dr. Mike Mekhiche, Program Director for HybriDrive Solutions, the
company’s new parallel hybrid system offers payback in about three to
five years. Other experts said payback out to seven years or longer—i.e., at some point within the vehicle’s anticipated life—could be enough for fleets to green-light green technology.
But still, a green fleet is attained at a
premium, and the price gap between electrified and conventional
technology must shrink for widespread adoption, stakeholders agreed.
“We really need pricing to come down,
but how do we get there with EVs?” asked Ken McKenney, Sustainable Fleet
Program Manager for Verizon, discussing
the keys for electrification expansion in fleet vehicles. “I think we
need to get standardization in the battery [in terms of size] and BMS
[battery management system] language protocols…If that could be
standardized, it would eliminate some of the anxieties that fleet
managers live with [servicing their vehicles].”
And, importantly, standardization could
help to drive down costs, he added. That’s what will ultimately put more
electrified vocational vehicles to work.
