High voltage solution
A system of integrated solutions including a cooled charging cable innovation
is helping EVs to charge faster, safer and go further on a single top-up
With an increasing number of
EVs on the road, the pressure
is on to maximize the power
capability of EVs to prepare them for
a long, uninterrupted journey. While
high-power charging infrastructure
is essential, there is also a vital
demand on the performance of high
voltage (HV) distribution in order
to e iciently conduct, hold, distribute
and use electric power after
charging. Huber+Suhner has been
addressing these requirements for
years and accelerated the growth of
EV performance with its innovative
solutions for high power charging
stations for electric cars, trucks and
busses around the world.
Addressing several electric vehicle
requirements, Huber+Suhner
recognizes a co-ordinated system
of integrated solutions is the
way forward.
Charging an EV must be quick,
e icient and reliable for cars to
maximize the distance they can
travel on one charge. With time of
the essence, charging systems must
be super-fast so EV drivers can
conveniently restore power and
continue their journey. With this
requirement in mind, Huber+Suhner
innovated a cooled charging cable
system for CCS1 and CCS2
interface. This provides the
possibility to charge the car for
100km in up to 3 min. The Radox
HPC system guarantees safe
performance for power delivery up
to 500A and 1,000V, is lightweight
and easy to handle. Several
thousand charging stations with
the Radox system are already
installed and in operation in
Europe and the USA.
Once the EV is charged, the
cabling within the vehicle is relied on
to transmit and protect the power as
it is stored in the vehicle. The cables
need to be of a certain quality and
must be resilient to withstand
various harsh environments while on
the move. At the peril of mechanical
abrasion, weather, moisture,
temperature, aggressive fluids,
Huber+Suhner Radox high voltage
cables are created with the Radox
material which solely protects the
cable from persistent environmental
conditions. With no further
protection needed, the high voltage
cables can be used in temperatures
from -40°C to +150°C (-40°F to
302°F) at a lifetime of 3,000 hours
without dissipation of their electrical
properties.
With the protective cabling
prepared to power up in any
environment, EVs must then hold
the high voltage power during a
range of driving conditions. In order
to hold, protect and secure the
power running throughout the
vehicle, high voltage automotive

The Huber+Suhner modular high voltage
distribution unit (mHVDU) addresses the
challenges of powering EVs
connectivity solutions must
withstand wide temperature
fluctuations, vibration and
mechanical impact. The Radox EV-C
cable feed-through protects the
cables from any damage and loss of
electrical performance. It is
designed for high current capacity in
harsh environments and only
requires minimal space.
The central function at the end of
the powering process is to distribute
the electrical power to and from the
HV battery to all electrical
components within the vehicle. The
Huber+Suhner modular high
voltage distribution unit (mHVDU) is
designed for seamless operation
and can be individually configured
to meet the unique requirements of
EVs. The next generation of the
mHVDU comes in a compact
housing and is equipped with
a range of standardized components
and covers a voltage range up
to 800Vdc.
Huber+Suhner has years of
experience in addressing the
challenges of powering EVs and
delivered high voltage solutions
to EV customers worldwide.
Appreciating that an EV requires
a full range of mechanical solutions
to transmit, hold and distribute high
voltage, the firm has developed a
range of advanced HV distribution
solutions which has accelerated the
speed at which EVs can charge and
use power e iciently for a fast,
uninterrupted journey.
