Testing and simulation expertise
Testing and verifi cation of
high-voltage batteries electric
and hybrid vehicle applications is
a common process, and requires
modern testing systems. Whether
it be performance, lifespan under
defi ned loads or environmental
conditions, the documentation
of charging and discharging
processes, or resistance
measurements, the systems used
for such applications not only need
to deliver the usual standards
of measurability, reliability and
reproducibility, but they must
also be cost-effective, safe and
fl exible. Innovative technology and
short delivery times have ensured
Heinzinger is well prepared to
cope with the increasing demand
of modern applications.
The ERS series from Heinzinger
has been successfully used
for more than 10 years in
sophisticated testing processes.
The series portfolio includes
different bidirectional DC sources
in all power classes. With special
software packages, such systems
can realize all applications for
battery testing and simulation,
including testing of further
powertrain components.
Heinzinger’s latest development
is a power output stage with
voltages up to 1,200V, currents
up to 1,200A and power of up
to 1.2MW in parallel mode.
A compact system for 48V

applications will also be released
in the near future. The system’s
strengths will include dynamics
and smart software functions.
A full range of products is currently
available, and will be expanded in
the future with a test sequencer, a
function generator and predefi ned
test sequences according to LV-
148. The primary technical data for
this is 60V output voltage, 400A
continuous current (500A peak)
and a power of 20kW.
