Thermal Modeling for
High Power Charging (HPC) of Electric Vehicles
optimized voltage path design and
thus benefits the level of safety be-
cause the simulated thermal load is
based on real-world conditions and
also considers aging effects. The
thermal behavior of components is
simulated within the on-board net by
applying accumulated test profiles
reflecting dynamic loads to com-
ponent testing. The ultimate goal is
to design components for the high
voltage path so they can carry the
short-time dynamic load of HPC DC
(10 minutes) safely over its com-
plete service life without static over-
dimensioning.
The simulation reveals hot spots
(mostly passive components with
low mass) that can be optimized
early on via design changes. This en-
ables systemic thermal simulation of
high voltage components to make a
substantial contribution to advanced
quality validation.
