Battery charging device using solar panel and coreless generator
By: Hemank lahir
BACKGROUND
1. Field of the Invention
The invention relates generally to battery charging device using solar panel
and
coreless generator
2. Background
Currently, there are a number of solutions for charging batteries (on a micro
level) using green energy solutions. Some of these solutions attempt to charge
batteries using inconsistent natural resources but these solutions fail to
meet
the needs of the industry because intense sunlight or wind are never
consistent.
Hydro power solutions lack portability. These solutions are very land
intensive,
pollute, require large distribution systems, which are not conducive for small
scale individual level energy consumers.
Other solutions attempt to increase battery storage capacities so that power
can
be stored when produced at the mercy of inconsistent weather, but these
solutions are similarly unable to meet the needs of the industry because
incorporating huge battery storage capacities to neutralize weather
inconsistencies is not at all cost effective.
Still, other solutions seek to use micro green energy solutions if consumers
happen to live closer to a falling water source, but these solutions also fail
to
meet industry needs because it is land intensive, and costly. It also requires
some level of competence for the upkeep and regular servicing of the
generator.
SUMMARY OF THE INVENTION
It would be desirable to have a green electricity source to charge batteries
which consistently provides power irrespective of weather conditions which is
non polluting, does not burn anything, has a long life with minimal
maintenance.
Furthermore, it would be desirable to have an electricity source which is
scalable , portable and is not land intensive. Still, further, it would also
be
desirable to have an electricity source which is economical in terms of
finances
and natural resources, which does not need a high technical expertise and can
be made with abundantly available recyclable resources. The disclosed device
advantageously fills these needs and addresses the aforementioned
deficiencies by providing an electricity solution which can be customized as
per
the individual application need ranging from a small electric vehicle to
household power requirements.

Disclosed is a solar powered, coreless generator battery charger, which is
made up of the following components: a 35 watt or higher solar panel, 4 AA
batteries, high torque motor, coreless generator, wind charge controller.
These components are connected as follows: The solar Panel is connected to
the 4 AA batteries which are charged continuously in daylight. These AA
batteries are used in series to turn a high torque motor. The high torque
motor
shaft is then connected using a connector to the shaft of the coreless
generator.
the coreless generator rests on bearings set on base to rotate freely. The
three
phase AC output of the coreless generator is connected to the wind charge
controller which converts AC to DC and this output charges 12 or 24 volt
batteries using its output clips.
The device may also have one or more of the following:
The coreless generator can be set directly on an extended shaft of the high
torque motor instead of connecting shafts to minimize potential energy losses.
The coreless generator shaft can also have a rounded side set on glass to have
a point friction base instead of bearings, this can help align the generator
with
its center of gravity to maximize output. The solar panel can be sized based
on
output requirements. The AA batteries connected to the solar panel can be
potentially replaced by capacitors or super capacitors to even further extend
the
life of the unit. The entire unit can be also have an encasement with the
solar
cells on the outer exposed side to make it portable. this can be made in
various
esthetic versions or visual or artistically pleasing encasements. The coreless
generator can have a different shape magnets, the coil can have thickness of
varying gauge. The rotor plates can have a varying diameter or even an a
visually different design. The coreless generator magnets can be of any type
available with varying size. The design can incorporate switches in different
areas to start and stop its working as needed. the design can also incorporate
indicator lights. The solar panel and AA batteries can be directly connected
to
the high torque motor or the charged AA batteries can be manually placed at
the terminals of the high torque motor. A second coil in the coreless
generator
can increase the availability of the charging options of the AA batteries
along
with the solar panel. A circuit connecting the solar panel and the second coil
of
the generator can also be created. The wind charge controller can be an
optional feature if a speed controller is added to the high torque motor, this
will
provide a steady output to match the charge requirements of the final
batteries
being charged. The high torque motor can be designed to internally incorporate
gears to achieve higher rotational speeds to match the required output needed
to charge batteries.
The disclosed device is unique when compared with other known devices and
solutions because it provides:
(1) A constant source to charge batteries using just day light even in
overcast
conditions;
(2) It is portable, requiring very minimal maintenance. Bigger household units
that use green energy solutions can potentially charge their battery banks in
a

few square feet instead of covering entire or sections of roofs. This also
reduces
the need for bigger battery banks and
(3) does not burn any fuel or have any harmful chemical biproduct, can be
made using non polluting abundantly available natural resource.
The disclosed device is unique in that it is structurally different from other
known
devices or solutions. More specifically, 1) this is a box shaped devise which
does not require land intensive solar panel array installation or tall wind
energy
towers. The outer shell can be designed as per application needs and is
portable unlike currently available solutions.
2) It is unique because it generates adequate electricity to charge 12 or 24
volt
batteries from just day light even in overcast conditions.
3) The rotation movement of the coreless generator is what produces the
electricity and the motion is sustained by the solar panel which constantly
charges the 4 AA batteries. The 35 watt and above solar panel only needs to
perform at approximately a tenth of its capacity and hence, this devise
overcomes the shortfalls of inconsistent weather.
This disclosure will now provide a more detailed and specific description that
will refer to the accompanying drawings. The drawings and specific
descriptions
of the drawings, as well as any specific or alternative embodiments discussed,
are intended to be read in conjunction with the entirety of this disclosure.
The
Battery charging device using solar panel and coreless generator may,
however, be embodied in many different forms and should not be construed as
being limited to the embodiments set forth herein; rather, these embodiments
are provided by way of illustration only and so that this disclosure will be
thorough, complete and fully convey understanding to those skilled in the art.

The solar panel steps down its charge to continuously charge the 4 AA
batteries
that are connected to the high torque motor's input leads. An on/off switch at
this juncture will turn on the high torque motor which will rotate the rotor
plates
of the coreless generator since their shafts are connected. The coreless
generator's shaft is suspended on a pair of bearings on each side. The
magnetic flux of the permanent magnets rotating around the coil of the
coreless
generator produces the desired electrical output. This output is AC current
which needs to be adjusted to match the DC charge requirement of the battery
to be charged. Commonly available wind charge controllers not only provide
this
function but also automatically detect 12 or 24 volt batteries. This generator
is
encased in a visually attractive outer shell with the solar panel being
outside.
The outer casing will be multi purpose of being visually attractive, ability
to be
set as a portable unit in EV applications with required fixtures etc., and be
made
out of environmentally friendly materials.
It should further be noted that: This is a battery charger only and not
designed
to run mechanical loads directly, this design is only to charge batteries.
Each of
individual component of this battery charger can be made from non polluting
materials.
Fig 1 shows the top view of the battery charging device using solar panel and
coreless generator, which is made up of the following components: a 35 watt or
higher solar panel (6), 4 AA batteries (1,2), high torque motor (7), coreless
generator comprising of its coil (9) and its rotor plates with magnets (13)
detailed in Fig 3 , wind charge controller (10).
These components are connected as follows: The solar Panel is connected to
the 4 AA batteries (1,2) which are connected in series to the high torque
motor
(7). The high torque motor shaft is then connected using a connector (11) to
the
shaft of the coreless generator. The coreless generator rests on bearings (12)
(detailed in fig 3) on each side which are set on a base (8) to rotate freely.
The
three phase AC output of the coreless generator is connected to the wind
charge controller (10) which converts AC to DC and this output charges 12 or
24 volt batteries (4) using its output clips (3,5).
Fig 2 shows the top view of the solar panel along with the side view of the
generator component, configuration details same as fig 1 description.
Fig 3 shows the details of the generator components of the battery charger.
A connector (11) joins the high torque motor (7) shaft with the shaft of the
coreless generator (12) . The shaft of the coreless generator extends outwards
to rest on bearings (12) on both sides so it can freely rotate. The rotation
causes electricity to be generated in the coil (9) which is 3 phase AC, when
the
magnetic flux of the magnets in the rotor (13) cuts the coil turnings from the
side. This is then corrected to 12 or 24 volt DC using a wind charge
controller
(10). The wind charge controller's output has battery clips (3 and 5 ) as
shown
in fig 1 and fig 2. This entire structure rests on a base (8) to give it
stability. The
solar panel can be fitted anywhere depending on the structural and space
availability of the 12 or 24 volt battery that is being charged.
