Of the megatrends shaping the automotive industry, electrification is
certainly one that has full government attention. Regulations for emissions
have been revised on a global scale, pushing auto makers to drive down
Global Electric Car Fleet Size(ii)
The cost to attain fleet targets is estimated at around €15
billoni. The move towards electrification isn’t just about
the change from a combustion engine to a hybrid or fully electric model, but
also about changing and updating vehicle production lines, deploying an
electrification infrastructure and increasing production capacity for
Vehicle Electrification Architectures
As the growth of hybrid and electric vehicles spreads, the market looks
increasingly fragmented. This means that a variety of approaches is needed to
fulfill the different needs present through the individual sections of the
Mild-Hybrid architecture is the first step in the chain:
where the cranking battery is up-sized to 48 V and switching to an electric
motor for cruising.
In a Full-Hybrid architecture, electricity is generated by
the combustion engine, but the car can run on full electrical cycles. Both
Full- and Mild-Hybrid use regenerative braking, engine start-stop and engine
assist to increase efficiency. Today, approximately 20% of electrified
vehicles sold are in the Mild- or Full-Hybrid categoryiii.

Plug-In-Hybrid and Range-Extended EVs switch
the predominant power source to the electric drivetrain and keep the
combustion engine to extend the ride. Compared to a traditional ICE engine,
CO² reductions range from 50 to 75 percent with this approach.
The Fully-Electric vehicle varies according to battery pack
size. Overall, battery pack capacity is increasing. Today, typical capacity is
around 10-13 kWh, or 50-65 km of driving range. The expectation is for it to
expand to around 70-80 kWh to deliver the 350-400 km driving range that
consumers wantiv. However, it is not just the battery pack capacity
that plays a role, but the entire electric chain through to the inverter in
the electric powertrain system.
Although these approaches present different electrification architectures,
there are common features that make moving seamlessly through to Fully
Electric powertrains achievable. Taking a new approach to designing for
electrification and combining the needs with inherent
is how we can move the market forward.
