Wireless charging technology overview and outlook
One,
the
history
of
wireless
charging
technology
actually
idea
of
wireless power supply have emerged as early as one hundred years ago,
in 1890, nikola tesla, the founder of the modern alternating current (ac)
system began to idea of wireless power supply method, and finally put
forward
a
very
ambitious
plan
-
the
earth
as
the
inner
conductor;
Between
the
earth
and
the
ionosphere
established
about
8
hz
low
frequency
resonance,
recycled
around
the
earth's
surface
electromagnetic wave to transmit power at a distance. At the time, tesla
is a series of experiments are carried out using coil, created the wireless
power
transmission.
In
1990,
and
tesla
began
his
research,
and
try
to
make
electricity
like
broadcast
across
oceans,
afterwards
because
of
huge
investment,
the
technology
of

Although
tesla
research
ultimately no results, but his original wireless power technology idea is
bold enough.
Second, the development of wireless charging technology tesla coil
at the time didn't get, but in the mid - 1920 - s, Japanese H.Y agi and S.U
da
theoretically
confirmed
this
solution
is
a
completely
different
from
special
power
supply
way
of
cable
transmission,
the
wireless
power
supply
technology,
photoelectric
coupling,
electromagnetic
coupling
main magnetic resonance, etc. Three different ways.
A
power
supply,
the
current
wireless
power
supply
technology,
photoelectric
coupling,
electromagnetic
coupling
main
magnetic
resonance,
etc.
Three
different
ways.
1,
electromagnetic
coupling,
electromagnetic
coupling
for
power
engineers,
in
the
familiar,
the
transformer
is
to
use
this
principle
to
transfer
energy.
If
separate
two
winding
transformer,
is
something
of
a
wireless
power
supply.
Rechargeable
electric
toothbrush
is
a
typical
case,
but
the
use
of

.
electromagnetic
coupling
way
has
a
lot
of
disadvantages,
not
high
magnetic
permeability
of
magnetic
core
as
a
medium,
the
lines
of
magnetic
force
can
lead
to
serious
spread
into
the
air,
resulting
in
a
decline
in
transferring
efficiency,
especially
when
two
coil
from
down
badly. So this way is only suitable for small power, close communication,
for high-power, long-distance wireless power supply is not so good this
way.
2,
photoelectric
coupling
photoelectric
coupling
is
to
convert
electrical
energy
to
light
energy,
such
as
laser,
energy
transfer
to
the
destination
by
light
into
electricity.
The
wireless
power
supply
technology is more intuitive, photoelectric coupling also can well restrain
interference,
and
the
application
of
the
photoelectric
conversion
technology
is
relatively
wide.
The
unidirectional,
but
made
by
light
transmission determines its transfer path has certain defects, there can
be no obstacles in the transfer path. So this kind of technology, also has
the
corresponding
defects.
3
people
on
magnetic
resonance
and
magnetic
resonance
coupling
has
a
noun
is
unknown,
its
principle
is
similar
to
the
principle
of
sonic
resonance,
if
the
two
media
have
the
same
resonance
frequency,
can
be
used
to
transfer
energy.
Magnetic
resonance chamber are currently studying a way of power transmission.
In
2008,
Intel
engineers
had
to
the
technology
as
the
foundation,
in
according to the power three feet lit a 60 w light bulb.
In
September
2010,
Fujitsu,
wireless
charging
technology
using
magnetic
resonance
between
the
charger
and
the
device
of
the
air
transport
charge,
the
coil
and
capacitor
in
resonance
between
the
charger and the device. Fujitsu said the system can be widely used in the
future, such as for electric car charging area and the power chip, power
transmission,
adopting
the
technology
of
the
charging
system
the
required charging time is only about one over one hundred and fifty of
the current. At present, Japan plans to set the charging points in 2012.
Also
developed
by
Fulton
eCoupled
technology
originated
in
the
19th
century
Faraday
discovered
electromagnetic
induction
principle,

.
when
the
current
through
the
coil
generates
magnetic
field,
the
corresponding equipment will be affected by magnetic field creates an
electric current, electric transmission is completed in
eCoupled technology can also be from of different functions of the same
electrical
appliances,
and
the
corresponding
power
adapter.
Initially,
Fulton
will
develop

on
the
power
of
new
technology,
companies
have
also
launched
their
own
research.
In

To
start,
as
numerous
manufacturers
and
research
institutions
in
order
to
achieve
the

power
practical,
also
began
to
actively
research
and
development.
In

Windows 7 in 2009 conference, Microsoft CEO Steve ballmer is brought
in the latest wireless video output and wireless power supply technology.
Wireless charging technology in city transport, also in March 2010, the
wireless charging of electric cars in Seoul, South Korea, large amount of
the first trial run in the park.
Fiver 1 wireless charging technology outlook, wireless charging on a
mobile phone application is one of the biggest mobile phone market in
China, and 60% of the world's mobile phones are made in China, so the
wireless charging technology is bound to take root in China. To realize
wireless
charging

the
current
must
have
two
parts:
transmitter,
connected
to
the
power

are
also
likely to be bundled with mobile phones for sale.
the first goal, after PMP/MP3 players, digital cameras, laptops, etc all can
use the new low energy consumption, high compatible wireless charger.
Is expected to realize long-distance wireless charging within five years.
How
in
the
future,
wireless
charging
technology
will
change
our
lives?
Convenient since needless to say, in addition, wireless charging is more
secure,
without
connector
leakage,
leakage,
electric
leakage
and
other
security
hidden
danger
can
be
completely
avoided.
Someone
worry
about
radiation,
this
technology
was
first
used
in
water
purifiers,
until
now already has eight years time, security has been validated by the 36
countries,
will
not
bring
harm
to
the
human
body
and
environment.
According
to
introducing,
wireless
charging
generally
is
through
the
electromagnetic
field
energy,
and
human
and
the
human
side
of
the
majority of items are magnetic. At present, the efficiency of the accept
rate continues to improve, will soon be able to achieve 98%. 2, wireless
charging technology application in medical equipment power supply of
implantable medical device at present rely mainly on implanted battery,
its biggest drawbacks is to deal with the problem after the battery runs
out,
whether
replacement
batteries
or
buy
permanently,
there
exist
hidden danger, therefore, the portable external for wireless charging can
be
implemented
as
low
power
wireless
sensor
network
(WSN),
can
be
recharged and patients medical devices implanted in the body, also can
recharge under the special circumstance of automatic test system. Some
implants volume is very small, can't accommodate the battery. Such as
cochlear, it needs to be surgically inserted instead of inner ear hair cells
play
a
role
of
an
electronic
device.
The
use
of
external
power
wireless
charging
methods
for
continuous
provide
high
can
for
implantable
medical
electronics.
Using
radio
frequency
links,
not
only
can
achieve
energy
transfer,
also
can
control
and
query
for
implantable
medical
devices. In addition, implantable medical electronics the service life and

.
storage life are no longer limited by the battery. For example, a cardiac
pacemaker (necessary power supply signal activation of cardiac recovery
and maintain normal), at present, the cardiac pacemaker implantation in
the human body, after 8 to 10 years or so need to replace the battery.
That
is
to
say,
although
installed
pacemakers,
then
every
eight
to
ten
years
will
also
need
to
be
an
operation
to
replace
pacemaker
cells.
Imagine if a pacemaker used the wireless charging technology, it is more
convenient? More don't happen surgical failures, chest infection, etc., the
postoperative quality of life of patients could get great improvement. 3,
the
wireless
charging
technology
application
in
mobile
intelligent
terminal
equipment
in
the
league
of
wireless
charging
technology
planning, the future of around 125 w high power electronic equipment
will
also
support.4,
wireless
charging
technology
in
electric
vehicle
application along with the rapid development of economy in our country,
the national corresponding preferential policies, the subsidy policy, still
in the new policy and a series of policies introduced gas energy, further
promoted
the
private
cars
increase,
the
international
energy
and
environment
has
become
the
world's
most
current
concerns,
and
alternative energy shortage, environment pollution and protection to the
developing of the new environmental protection. The electric car is the
first developed a kind of environmentally friendly new energy vehicles,
including
battery
electric
vehicles,
hybrid
electric
vehicles
and
fuel
cell
electric cars. The battery electric vehicle technology has matured, many
manufacturers
have
begun
to
production,

also
in
the
construction
of
charging
stations.
But
the

has
been
the
researchers
have
a
headache,
and,
therefore,
solution
of
charging
technology,
will
greatly
promote
