FIELD OF INVENTION L
The present invention relates to an improved electric power based vehicle
and in particular relates to a three-wheeler electric cycle rickshaw with an
improved battery performance output.
BACKGROUND OF THE INVENTION
The statements in this section merely provide background information
, related to the present disclosure and may not constitute prior art(s).
In a general trend, the automotive vehicles, running on gasoline fuel, are
being transformed either to hybrid vehicles or vehicles that can run on renewable
sources of energy or electric power sources of energy such as batteries. These
electric.power based vehicles are low in an amount of an exhaust gas and good in
fuel consumption. For instance, a lithium ion battery is widely used as a leading
power so,wce in e-rickshaws considering the high energy density of these lithium
ion batteries. However, the electric ,power based 'vehicles are not so popular in
market due to which it is not being easily acceptable by the customers. One of
. these major concerns include the constant and regular need of charging the battery
of these electric power based vehicles. This leads to charging the batteries for
atleast twice a day so that the operatorldriver can earn his living for the day. This
may affect' the profit quotient of the operatorldriver if the charging is required
during the peak hours of the business. Additionally, frequent charging of the
batteries of the electric power based vehicles tend to reduce the lifespan of the
batteries also. Although there may be multiple ways of enhancing the charge
capacity of the batteries such as by using a flywheel for storing the energy, by
carrying a portable power bank for charging the lapsed battery during travel, by
increasing the number of batteries, and many more. However, all these mentioned
solution will simply add to the overall buying cost of the electric power based
vehicles and thus more pressure on the poor buyers. Therefore ky such new
concepts could not be commercially accepted due to other drawbacks such as
complexities involved, less efficiency, non-reliability, robustness, extensive
manufacturing cost, and the like.
I In other words, we must improvise the batteries if we need an efficient and
productive output of the electric bower based vehicles. For instance, as a
guideline, each 8°C (15°F) raise in temperature cuts the life of a sealed lead acid
battery in half.' A Valve regulated Lead Acid battery for stationary applications
that will last 10 years at 25°C (77°F) would only live five years if operated at
33°C (92°F). The same battery would cease after 2% years if kept at a constant
desert temperature of 41°C (106°F). Once the battery is damaged by heat, the
capacity cannot be restored! Further, we should note that the life of the batteries is
more affected in summer than in winters.
Hence, there is an urgeit need to check and control the capacity of the
I
I battery from getting discharged quickly so that the efficiency and productivity of
I the electric power based vehicles may also get enhanced without losing the basic
I
I requirements of reliability, safety, less cost, customers' satisfaction and the like.

The present invention relates to an improved electric power based vehicle
and in particiilar relates to a three-wheeler electric cycle rickshaw with an
improved battery performance output. The following description is merely
exemplary in nature and is not intended to limit the present disclosure,
application, or uses. The present invention will hereinafter be described in detail
below as applied to the three-wheeler electric cycle rickshaw. However, the
principles of the present invention are also applicable to other electric power

electric cycle rickshaw.
FIG. 1 illustrates a perspective view of the three-wheeler electric cycle
rickshaw 100 in an accordance with an embodiment of the present subject matter.
The three-wheeler electric cycle rickshaw 100 include a chassis 102 supported on
an axle hold on the rear wheels 106 mounted rotatably on a rear shaft 108 of the
. .
three-wheeler electric cycle rickshaw 100. In an embodiment.of the present
subject matter, the three-wheeler electric cycle rickshaw 100 is ergonomically
provided with a seat 110 mounted on a battery container 112 placed above a main
chassis frame 114 provided with the three-wheeler electric cycle rickshaw 100.
The battery container 112 is positioned at the main chassis frame 114 in a driver's
compartment separated by a frame tube 124 on the rear portion of the main
chassis fi-ame 114 of the three-wheeler electric cycle rickshaw 100. The frame
tube 124 further spaces a passenger's compartment 126 on the other side of the
driver's compartment 128. The three-wheeler electric cycle rickshaw 100 is
linther provided with a front wheel 136 supported on a front end of a frame 116,
in an embodiment of the present subject matter. The three-wheeler electric cycle
rickshaw 100 is equipped with a switch (not shown) on its handlebar 118 to
control an electric motor (not shown) provided with the three-wheeler electric
cycle rickshaw 100. The three-wheeler electric cycle rickshaw 100 is 'also.
structured with the vehicle information display instrument 122 (as shown in FIG.
2) (also known as a speedometer) located between the handle bars of the threewheeler
electric cycle rickshaw 100. The vehicle information display instrument
122 may be viewable by the rider of the three-wheeler electric cycle rickshaw 100
when the rider is seated on the seat 110 and operating the vehicle 100. The vehicle
information display instrument 122 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
vehicle information display instrument 122, which information may indicate an
operating condition or conditions of the vehicle 100. The vehicle information
display instrument 122 may be provided with audiolvisual 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 andlor
other indicators. Further, the electric power based vehicles 100 is hold by a brake
means such as brake rod 104 mounted on the rear wheel axle to stop the electric
power based vehicles 100 as and when required. Also, a brake lever is provided
with the handle of the electric power based vehicles 100 to actuate the brake
means as required. Additionally, the electric power based vehicles 100 is also
provided with a first-aid box (not shown) and a fire extinguisher (not shown). The
electric power based vehicles 100 is further powered with pluralities of LEAD
acid batteries 120 placed in the battery container 112, as shown in FIG. 1, to
provide electrical energy to the electric motor.
Generally, the battery 120 is structured of a casing encompassing plurality
of positive plates ?lead oxide) and negative plates (Lead) arranged in a pre-defined
required fashion. Further, the battery 120 is also provided with sulfUric acid that
I surrounds the negative and positive plates. Importantly, the battery is provided
with atleast two terminals used to connect a load or a charger to a single cell or
1 multiple-cell battery for supplying power to the devices. In the electric power
based vehicles, 100 the battery 120 is held by a metallic clamp 130 with two
longitudinal supports 132 screwing the metallic clamp 130 to tight-hold the
battery 120 within the battery container 112. FIG. 2 shows a perspective view of
the LEAD acid batteries 120 placed in the battery container 112 as being
implemented in the electric power based vehicles 100 of prior art technologies.
However, the metallic clamp 130 being used in prior art technologies to tight-hold
the battery 120 within the battery container 112 starts behaving like a conductor
once come in contact with the LEAD acid leaking through plurality of blind plugs
(not shown) provided'on the top of the battery 120. Hence, this conductive
metallic clamp 130 subsequently transfers the current to be generated by the
LEAD acid to the ground terminal via the two longitudinal supports, thus forming
an electronic circuit. This leads to the leakage and wastage of important voltage
capacity of the batteries which may be used to drive the electric power based
vehicles 100 more, especially during the deficient power back up in the batteries
of the electric power based vehicles 100.
Nevertheless, in an embodiment of the present subject matter, the above
explained metallic clamp ,130 is replaced with an insulated metallic cap 134 to
tight-hold the battery 120 within the battery container 112 in a similar manner a3
was being done in the prior art technologies, as evident from FIG. 4. The
significant difference is that of the insulated metallic clamp 134 as shown in FIG.
3. The insulated metallic clamp 134 is an insulation of polyvinyl chloride coated
on the metallic clamp 130 in an embodiment of the present subject matter. The
.$, -,z. .- :-* 22- .. ,.. * . I.i'. W - gpu : . -. . - -. . . . .- ..- .- .- ,-

coating may be of other material such as chlorinated polyvinyl chloride and the
like. Therefore, in an embodiment of the present subject matter, the insulated
metallic clamp 134 is holding the battery 120 with the help of two longitudinal
supports 132 screwing the insulated metallic clamp 134 to tight-hold the battery
120 within the battery container 112. The presence of this insulated metallic
clamp 134 diminishes the possibility of the electronic circuit and thus lessens the
'leakage and wastage of important voltage capacity of the batteries 120. This
consequently increases the capacity of the battery 120 which subsequently
increases the running distance of the electric power based vehicles 100 in an
embodiment of the present subject matter. In other words, the replacement of the
metallic clamp 130 with the insulated metallic clamp 134 revamps the long
standing issue of regularly charging the battery 120 so that the insulated metallic '
clamp 134 can go on a longer distance.
In another embodiment of the present subject matter, various tests have
also been conducted by the applicant to physically verify the result of increased
capacity of the battery with and without the implementation of the insulated
metallic clamp for holding the battery within the battery cover. Those tests are
done under the following conditions:
b
A) Nominal Tyre pressure should be 36Psi (250Kpa) in cold condition of Tyre.
B) Battery should be full charge 52V nominal.
'C) Brakes should not get jammed.
D) Road condition is good.
E) The maximum permissible speed limit of the electric power based vehicles.
F) The route of the testing vehicle should not be changed.
G) The rider should not be changed during subsequent testsltrips.
H) The vehicle should always be equipped with vehicle toolkit, multimeter and
other necessary test related equipments.
I) The vehicle should be thoroughly checked before each tests.
The tests and their results are as tabulated below:

Therefore, the above experiment also proves that the implementation of
the insulated metallic clamp raises the overall travel distance of the three- wheeleielectric
cycle rickshaw merely because of the fact that the voltage capacity of the
battery is kept intact. with the control of leakage of LEAD acid from the battery of '
the three-wheeler electric cycle rickshaw. In other embodiment .of the present
subject matter, the improved three-wheeler electric cycle rickshaw provided with
the insulated metallic clamp advantageously facilitates the improvement in the
overall running distance. of the electric power based vehicles from an approximate
travel of 63 km to 78 km per charge of the battery. Further, the control of leakage
of LEAD acid through the insulated metallic clamp and the longitudinal supports
will enhance the safety of these three-wheeler electric cycle rickshaw.
Additionally, the lifespan of the battery also gets automatically increased due to
less frequent charging of the battery. Moreover, since the travel distance of the
three-wheeler electric' cycle rickshaw tend to increase with the application of
insulated metallic clamp, hence the unnecessary cost of multiple batteries can also
be avoided leading to a less costly and yet efficient three-wheeler electric cycle
rickshaw.
It will be appreciated by those skilled in the art that changes could be
made to the embodiments described above without departing from the broad
inventive concept thereof. The present embodiments are therefore to be
considered in all respects as illustrative and not restrictive, the scope of the #
invention being indicated by the appended claims rather than by the foregoing
description and all variations, substitutions and changes which come within the
meaning and range of equivalency of the claims are therefore intended to be
embraced therein.
