COVER STORY
required to cover long distances and constantly
pass by the charging station. It is our
assumption that electrified ground support
equipment at airports will rise above their
niche status, " adds Jochen Preßmar, senior
project engineering manager for electric vehicles
at Goldhofer.
With many airports declaring goals to
reduce ground emissions, Webasto and Goldhofer
have partnered to optimized Goldhofer's
cargo and pushback tow tractor, the Sherpa E
New Gen. Introduced in 2017, the Sherpa E
offers quiet and emission-free operation. With
an intelligent charging infrastructure, it offers
additional benefits.
Besides an expanded performance range
and extended service life, the enhanced version
can be charged more quickly and with
greater flexibility and provides for longer
maintenance cycles and lower operating
costs. The new model now comes with a
gearless direct drive that generates a torque
of up to 1,050 Nm. It is powered by a modular
battery system with intelligent temperature
management.
Several factors prompted Goldhofer to turn
to Webasto to supply the battery power necessary
to operate the Sherpa E.
" Imposing exacting requirements and
placing prime importance on the quality and
longevity of our vehicles, we take great care to
only use components that offer great promise
and that allow us to maintain our high standard
of quality, " Preßmar says.
" Depending on the version and in line with
the customer's specific requirements, we equip
the Sherpa E with one or two Webasto batteries,
each generating 35 kWh, " he adds.
Webasto's battery solution has been subjected
to electromagnetic compatibility testing
and therefore does not interfere with radio
or electronic components. Additionally, the
modular design of the battery system allowed
Goldhofer to use the power source across multiple
types of GSE units.
" We have diverse vehicle ranges of different
sizes and requirement levels. We identified
Webasto as an all-rounder for the Sherpa and
Bison product segment, which offers us as a
company the option of modular construction, "
says Rüdiger Dube, head of product management
airport technology at Goldhofer.
Goldhofer currently utilizes lithium-nickel-manganese-cobalt-oxide
batteries. Company
officials note the energy density provided
by these units is ideally suited for their
applications.
" It is our hope that energy density on the
cell level will keep increasing in the future, "
adds Preßmar.
Goldhofer is currently aiming for at least
eight years of battery life from the current
units. After that time, Webasto officials note
the battery should still deliver significantly
more than two-thirds of its original output
capacity.
" It remains to be seen if the customer will
actually switch batteries or merely opt to make
slight variations to their cycle, " notes Preßmar.
