E-DRIVING CYCLES
and designed. As an example, the
battery size can be perfectly adapted
to the requirement profile. In the
e-drive cycle, the areas in which the
vehicle draws power are shown in
detail, and at the same time the
recuperation phases are shown in
equal measure. The battery capacity
can thus be optimally adjusted on
the basis of the driving cycle.
Another example would be
the electric motors, the power
electronics and ultimately the entire
vehicle. The detailed load
requirements from the e-drive cycle
also make it possible to achieve
weight savings as it can become
apparent the original vehicle is
oversized.
Outlook for electric driving cycles
The comparison of conventional
driving cycles to the required load
requirements / driving profiles of
NRMMs clearly shows a need for
specially adapted driving cycles for
this type of vehicle. The current
driving cycles in the WLTP under
RDE conditions do not yet allow an
exact evaluation of the large
differentiated variety of drive types
and operating conditions. After the
development and research of the
required load requirements,
NRMMs can be developed and
designed more efficiently in the
future. The vehicles can be
optimised with precisely defined
requirements for range, engine
performance, climbing capabilities
and speeds. The performance of the
batteries and the complete power
electronics can be dimensioned
according to the requirements. The
vehicles thus become more energyefficient
and environmentally
friendly overall. CO2 emissions
and environmental pollution
will be reduced and the vehicles
will become part of a more
sustainable future. iVT
