2. SMART GRIDS
The networks of the future
There is no doubt that we are witnessing a
moment like never before in our society due
to the computer revolution and the advance
that this has brought to society. However,
sometimes we can ignore the true applica-
tions that this digital progress can have in
daily life.
The electricity industry is not excluded from
the digital advance, it is increasingly called
for a transformation: an evolution from a
centralized network to a more derived one
that would require greater interaction by the
consumer. This is where smart grids come
into play, a new way of understanding and
managing electricity efficiently.
a future version of our electrical networks;
This would suppose a new paradigm at the
time of consuming electrical energy.
To provide intelligence to traditional electrical
networks, telematic readout meters are added
that allow real-time consumption to be known,
both for the company and the end user. In
addition, with these data you can learn con-
sumption habits and improve the efficiency of
the network, as well as contribute to energy
savings.
To carry this out, the smart grids shall incorpo-
rate an automated computer system, capable
of automatically responding to fluctuations in
energy production, but also in demand. Thus, a
situation will be reached in which both the end
user and the distributor have more information
about consumption, and in which more respon-
sible use is made throughout the cycle: from
generating
plants to the
domestic
system.
An ideal combi-

Smart grids and
smart meters,
allow consumers to know in real time how
much energy they are consuming and at what
price, to decide if they want to disconnect from
the grid to self-build energy of their own gene-
ration.
Smart grids are “crawling”, and there is still a
long way to go. However, these are the lines to
follow in terms of energy efficiency and
savings, within the growing desire to build a
sustainable world.Any gesture in our hand can
make a difference in terms of efficiency. And
smart grids will definitely be the grids of the
future.

Using the internet, a Smart grid uses compu-
ting and home automation tools, as well as
the most cutting-edge technology and the
most innovative equipment, to give a firm
response to the volatile demand for electrici-
ty. And we must remember that electricity has
a particular nature: it has to be consumed
simultaneously at the time of its generation.
This is why the energy that is not consumed
is often lost, and at a time like this, when we
seek maximum energy efficiency, we must
seek solutions. And the smart grids are, since
they will be the emblem of a transition toward

3. Electric vehicles are here to stay, just look at
the increase in production of the automotive
industry with previous years. High-performan-
ce cars like the Tesla model S or the BMW i3
are already seen strolling the streets. And
this will be seen more frequently in the near
future.
Factors such as the decrease in prices as the
degree of penetration of electric vehicles in
the market increases, the prohibitions in the
horizon in Europe (2040) for the registration
of combustion vehicles, the increase in envi-
ronmental awareness or restrictions on Pollu-
ting car traffic encourages slow but safe
progress towards this technology and a new
paradigm shift.
In order to understand this concept of mobili-
ty and how electric car recharges are carried
out, it is
worth clarif-
ying certain
principles.
On the one
hand we have
the type of
recharging,
on the other
the types of
connectors
and finally,
the rechar-
ging mode.
Type of recharge in the domestic
sphere
Cars support various types of recharging.
Standard slow recharging is typically common
and would fully charge an electric car battery
in about 6-8 hours.
Given that in the domestic environment most
people enjoy a single-phase supply and a
contracted power that does not exceed 10kW,
the power of the recharging point is usually
3.7kW (16A at 230V).
But recharging the car can also be done using
a conventional plug (called a Schuko). Howe-
ver, in this case the intensity of it will not
exceed 13A, extending the charging process
up to about 10 hours.
If the supply has sufficient contracted power
and the cart allows it, quick standard rechar-
ges can be performed. In this case, the pro-
cess would take just over 3 hours.
Types of recharging on public roads
In this area (large dwellings, public parking
lots, etc. that have a three-phase supply)
there are semi-fast recharges. In just an hour
they can recharge an electric vehicle.
In this case the powers are 11kW (16A at
400V) and 22kW (32A at 400V). Depending on
the vehicle model, said recharging could be
done alternately, continuously or both.
For its part, fast recharging is offered in elec-
trolineras with a power of 50kW or even
higher. In just 25 minutes you can recharge
80% of the battery.
In order to enjoy this type of recharging, the
car must be compatible with the ChaDeMo or
CSS combo connectors.
