Appropriate EV power
A fresh approach to EV charging infrastructure is making the task of
locating charging stations in and around major cities across the world simpler
The Keywatt charging station incorporates a compact universal charging solution suitable for all users, regardless of vehicle

Atmospheric pollution is a
major concern for all cities,
due to CO emissions but also
related to NOX particles that
adversely a ect public health.
Around the world, many initiatives
are today being considered and put
into action to limit those health risks.
The transition toward green
transportation, either private, public
or shared, is one of the key areas
contributing to cleaner air.
To accelerate such transition, we
can see today decisions from many
cities to restrict, even ban, access to
their centers by ICE vehicles.
Incentives, such as free parking and
access to bus lanes, are also
provided to increase adoption of EV
by urban citizens. However, a
majority of citizen living in our cities
do not own a private car park, or an
access to a plug. In consequence,
charging in the public place needs
to be considered as a key enabler.
The option to set-up a slow
charging infrastructure, where
people could park and charge their
cars in the night is possible, but this
clearly raise the concern of a ecting
the city scape, due to the high
number of charging points needed.
Finding an available on-street
parking space within the city can be
sometimes challenging, finding one
with a charging station, and, on top
of this, free, may be even more
troublesome. Another aspect to be
considered is related to the energy
consumed for daily transportation to
be charged.
On average, citizens commuting
between home to work in cities drive
less than 30km (18 miles) per day.
Therefore, on the basis of 15kWh
consumed every 100km (62 miles),
the amount of energy needed for
charging on a weekly basis is in the
range of 22kWh.
This means that EV owners would
only need to charge their car once a
week rather than every night, while
on the weekends vehicles could be
charged while owners are busy with
other activities. For example,
charging while owners shop in
commercial centers or go to
restaurants and movie theaters
makes the most of the idle time.
Usually, the time spent doing these
activities ranges from one to two
hours, so o ering the opportunity
to charge the 22kWh within this time
would provide a value and
convenience to many EV owners.
At IES, it is introducing new
solutions designed to ease the
deployment of such a charging
infrastructure. Our new Keywatt
with its rated power of 24kW,
provides the right level of charging
speed compatible with this
destination model, and at a much
more a ordable cost compared to
50kW stations considered so far.
Thanks to its lower power,
requiring less powerful electrical
gears to install and less energy to
run, meaning lower subscription
costs, the overall cost of ownership
is much reduced, up to three times
less. In France for instance, the
possibility to use a ‘Tarif Bleu’
subscription (below 36kVA) brings
ease of installation and a muchreduced
energy yearly fee.
With its multi-standard design,
the power station supports all
electric vehicles available on the
market (from Combo, CHAdeMO to
AC 22kW) and provides a truly
universal solution. And thanks to the
possibility of charging both the DC
and AC plugs simultaneously, it
provides two charging points with
more rotation possible.
Designed for use in the city
environment, the new station can be
easily installed against on a wall, on
a curb, with a minimized foot-print
needed. Thanks to its sealed design
which has no air filters, maintenance
needs are greatly reduced and life
time extended. This new concept
has already been selected by La
Metropole du Grand Lyon in France,
with Demeter-IZIVIA set to install
100 stations within this year.
It is clear a new set of services
to encourage EV adoption within
the city are underway, and IES has
the vision and ambition to facilitate
this transition.
