FIELD OF INVENTION
The present invention relates generally to wireless charging, and more
I1 specifically to devices, systems, and methods related to wireless chargeable device
for vehicles such as two wheelers, three wheelers, and the like.
I The statements in this section merely provide background information related
to the present disclosure and may not constitute prior art(s).
Generally, battery powered chargeable devices such as cellphones, trimmers,
I toys, etc require its own charger and a compatible power source ~~sualcloyn nected to
I an AC power outlet to.get the device charged before the power of the device gets
I depleted. In electric and hybrid vehicles, rechargeable batteries are provided in their
I drive systems that must get charged before the power of the device gets exhausted.
I These electric and hybrid vehicles are connected to an electric charger or any similar
I wired connection for charging the batteries. Hence, charging the cellphones (or other
I similar chargeable devices) during the travel or even charging the rechargeable
I batteries with the electric charger or any similar wired connection becomes tedious
I and impossible for the user too. Further, it becomes unwieldy when many devices
need charging, each requiring its' own separate charger. As an advancement to this
' .kind of technologies, wireless power transmission are being developed between a
transmitter and a receiver coupled with the device. The receiver is provided with a
receiver antenna that collects the radiated power and hrther rectifies the radiated
power to the device to be charged. The receiver antenna further collects the radiated
power and rectifies the radiated power for charging the battery. However, the power
coupling (in this method) falls off quickly with the distance between the antennas, so
charging becomes difficult over a reasonable distance. Moreover, unintentional
radiation may also interfere in the process if not filtered precisely. I:urthermore, the
wireless power transmission is practically not feasible in case o:f vehicles wherein the
charging of the chargeable device sometimes become essential for the operator during
travel. The precision with which wireless power transmission must be implemented,
is extremely important. This limits the use of wireless power transmission of high
energy to very controlled environments, making difficult its use in the power transfer
to moving vehicles. On a general note, chargeable device such as cellphone wired
chargers are constantly subjected to wear and tear due to constant plugging of
chargers that subsequently lead to reduced life of such chargers. In other words, the
more times the plug in the cord is utilized, the sooner that port will quit working.
Broken Charging .ports are a common issue and normally when the charging port
goes bad the phone isn't worth spending the money on to fix it.
Therefore, it is an object of the presdnt invention to provide a n~.ireless
chargers for chargeable devices which does not suffer from the foregoing drawbacks.
Also, we need an advanced wireless charging system without losing the basic
requirements of reliability, safety, less extra cost: customers' satisfaction and the like.

cycle 100. However, the principles of the present invention are also applicable to the
chargeable device 300 that can be placed on a vehicle information display instrument
of two wheelers and vehicles 100'such as three wheelers, four wheelers, and the like.
Upward, lower, front and rear directions of the two wheeler (see the directions
indicated by the arrows in FIG. 1) will be described with respect to directions as
seated by the rider on the motorcycle 100. Also, the present subject matter discusses
the charging of the chargeable device 300 that may, include cellphone, trimmers, toys,
motorized wheelchairs, golf carts, electric bicycles, and the like.
FIG. 1 illustrates a two wheeler .lo0 that may include a fuel tank 102 and an
engine mounted ahead of a rider's seat 1.04, a :frame 106 and two relatively large sized
wheels 108 on which the frame 106 rides. Thd structure is necessarily provided with a
pair o£.lefi and right front fork members rotatably supported by a head pipe 110 on
the front end of the vehicle frame. The steering of the two wheelers 100 is possible
via a front wheel which is mounted on the front fork nlernber whereas the . rear wheel
(drive wheel) is at the rear end. FIG. 1 shows a handlebar 112 secured to an upper
portion of the front fork member, and the front and rear portion of the handle bar 112
is covered with a handle cover which is further .divided into forward and backward
portions. The two wheeler 100 are also with various lights mounted
externally on the vehicle to indicate certain information about the vehicle to other
drivers and pedestrians. These lights mainly include brake lights and tail lights
besides indicator light bulbs which ark provided to indicate the driving direction of
the two wheelers. The two ;heeler 100 is further provided with the intelligent vehicle
information display instrument 114 (as shown in FIG. 2 later) (also known as a
speedometer) located between the handle bars 112 of the two wheeler 100. The
vehicle information display instrument 114 may be viewable by the rider of the motor
cycle 100 when the rider is seated on the seat 104 and operating the vehicle 100. The
vehicle information display instrument 114 may be disposed generally in front of the
rider so that the rider can inspect or view a variety of information that form part of
the behicle information display instrument 114, which information may indicate an
operating condition or conditions of the vehicle. The vehicle information display
instrument 114 may be provided with audio/visual warning indicators comprising
information such as speed, the fuel level, telephone, bluetooth, rpm of the engine, tell
tale symbols, turn signal indicator, hazard warning indicator and 1 or other indicators.
FIG. 1 further shows a headlight 116 provided, as an attachment to the top middle of
the handlebar of the motor cycle, to light the road ahead.
In an embodiment of the present subject matter, FIG. 2 discloses a front
perspective view of the vehicle information display instrument 114 provided. with a
basic outer body onto which a printed circuit board 118 is assembled supported by the
basic body. The printed circuit board 118 iiiainly iiiechanically supports and
electrically connects electronic components using conductive tracks, pads and other
features etched from copper sheets laminated onto a non-conductive substrate. In an
embodiinent of the present subject matter; the printed circuit board 118 also
comprises of atleast a transmitter coil 120 within which an alternating magnetic flus
is created wliicli is subsequently converted into an electric current in a receiver coil
122 as shown in FIG. 2. In an embodiment of the prcsent subject matter, the rcceiver
coil 122 is fitted at the rear end of the chargeable device 300. Depending on the
distance between the transmitter coil 120 and the receiver coil 122, only a fraction of
the magnetic flux generated by the transmitter coil 120 penetrates the receiver coil
122 and contributes to the power transmission. The more flux reaches the receiver
coil 122, the better the coils are coupled. Therefore, the chargeable device 300 must
be kept in close proximity to the transmitter coil 120 in order to achieve a high
transfer efficiency with reduced losses and heating. This is because, only a fraction of
the transmitted flux is captured in the receiver coil 122 in loosely coupled systems.
That means that loosely coupled systems have higher electromagnetic emissions,
making them less suitable for applications with tight E-M1 or EMF requirements. In an
embodiment of the present subject matter, the transmitter coil 120 is placed in contact
with the receiver coil 122 at a distance ranging from 40 cm to 50 cm. In a unique
embodiment of the present subject matter, the chargeable device 300 are placed on a
chargeable device stand 302 provided. on the vehicle information display instrument
1 a- 114 in such a way that the rear portion of the chargeable device 300 (equipped with
receiving coils 122) gets in contact with the transmitter coil 120 provided within the
vehicle information display instrument 114 of the vehicle 100.
FIG. 3 discloses an electronic circuit structure 200 provided to govern the
operation of wireless charging of chargeable device 300 placed on the vehicle
information display instrument 114, in an embodiment of the present subject matter.
The electronic circuit structure 200 illustrates a battery powered ignition switch 202
which when turned therein with an ignition key (not shown) activates an engine (not
shown) of the motor cycle 100. The electronic circuit structure 200 is provided with
an interface 204 that refine and supply a regulated voltage of 5 V (:from the battery
supplying a voltage o:f 13 V) to a micro-controller 206 provided with the electronic
circuit structure 200 of the vehicle information display instrument 1.14. The microcontroller
206 is designed to receives signals after sensing the position o-f the
chargeable device 300 (provided with a receiver coil 122) on the chargeable device
stand 302 (designed with a transmitter coil 120 underneath) providdd on the vehicle
information display instrument 1.14. In an embodiment o:f the present subject .niatter,
the transmitt-er coil 120 and the receiver coil 122 are actually a twin-core copper wire.
In an embodiment of the present subject matter, the transmitter coil 120 'is provided
with the printed circuit board 118 of the vehicle information display instrument 114.
The receiver coil 122 is smartly placed within the rear side of the chargeable device
300 in an embodiment of the present subject matter as shown in FIG. 3. The
electronic circuit structure 200 further explains that the transmitter coil 120 gets
energized with the input from the battery provided with the vehicle 100. In an
embodiment of the present subject matter, the two end of the transmitter coil 120 are
respectively connected to an integrat~d circuit 208 as shown in FIG. 3. The said
transmitter coil 120 comes in contact with the receiver coil 122 as shown in the
electronic circuit structure 200, as explained later. In an embodiment of the present
subject matter, the integrated circuit 208 may bereplaced with a transistor also. -?She
status of the charging of the chargeable device 300 is evident in the .form of a telltale
210 on a dial plate (in a mechanical vehicle information display instrument) and on a
displaying screen 212 (in an electronic vehicle inforn~ation display insrrument). In an
embodiment of the present subjdct matter, the signals received by the microthe
same on an "active-matrix TFT" screen on the vehicle information display
instrument 114 of the vehicle 100. In a unique exemplary embodiment of the present
I subject matter, the vehicle information display instrument 114 may be provided with I I
an exhaust fan (not shown) to vent out the hot air generated while charging the
chargeable device 300.
Operationally, as the chargeable device.300 is placed on the chargeable device
stand 302, the receiver coil 122 comes in contact with the transmitter coil 120.
I Parallely, the transmitter coil 120 receives a pre-calculated voltage from the battery I
I provided with the \~ehicle 100 that s~~bsequentliyn duces a time varying magnetic I
I field in the transmitter coil 120. The voltage flowing within the transmitter coil 120 I
induces the time valying magnetic field which extends to the receiver coil 122
I (necessarily placed within a speci:fied distance). As a result 0.f which, the magnetic I
field generates current within the receiver co'il 122 of the device. The same current
charges the battery o:f the chargeable device 300 placed on the chargeable device
. . stand 302 on the vehicle information display instrument .of the vehicle. In this
en~bodin~eonft the present subject mater, the receiver coil 1.22 is solely responsible to
receive the magnetic field o r generating the, current in the battery of the chargeable
I device 300 placed on the chargeable device stand 302 of the vehicle information I
