EV Electrification Architectures to Know
The Mild-Hybrid architecture has a cranking battery up-sized to
48V and switches to an electric motor for cruising.
The Full-Hybrid architecture uses the combustion engine's
electricity, but the car can run on full-electrical cycles. Both Full-
and Mild-Hybrid use regenerative braking, engine start-stop,
and engine assist systems to increase efficiency.
The Plug-In-Hybrid and Range-Extended architectures switch
the predominant power source to the electric drivetrain and
keep the combustion engine to extend the ride.
The Fully Electric architecture relies not just on the battery
pack but the entire electric chain through to the inverter in the
electric powertrain system.
The electrification market is growing faster than expected.
The Fully Electric powertrain now seems achievable, taking
advantage of the standard features of these different electrification
architectures. The EV sales forecast (Figure 2) is sparking
appeal and is expected to reach a third of sales by 2025.
Understanding how to control the power in electrified systems
efficiently is one key aspect of the EV market: integrating
the long-standing principles of functional safety and security
with the zero-defects quality approach and its high-volume
production. Another slightly new key factor is connectivity;
while previously powertrains were not connected to the outside
world, the EV systems incorporate external data to optimize
battery range and reliability. An example includes looking at the
optimum route toward the planned destination, collecting and
considering sensor data from the car's surroundings.

Figure 2: The expected uptick in electric vehicle sales is largely a result of a drop in the total cost of EV
ownership. Government incentives, tighter regulations of tailpipe emissions, growth of the EV charging
infrastructure and falling battery prices also are significant factors in the increase. (Source: BCG analysis)

Conclusion
Electrification will continue as a
megatrend shaping the automotive
industry. Carmakers must overcome
the challenges of electrification by
selling enough EVs to comply with
the stringent regulatory emissions and
fuel-economy targets while maintaining
profitibility despite the cost of battery
packs. Nevertheless, new potential use
cases for EVs will power new e-mobility
applications: passenger vehicles, light-
commercial vehicles, and medium to
large trucks.
