A SMART CHARGE AND POWER SUPPLY DEVICE FOR VEHICLES AND
MOTORCYCLES
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention relates to a smart charge and power supply device for
vehicles and
motorcycles, and particularly to a smart charge and power supply device for
vehicles and
motorcycles which provides increased efficiency by extending the run time of
power supply.
2. Description of Related Art
[0002] In face of the global worsening air pollution problem, governments all
over the
world have been actively encouraging industries to develop electric vehicles
and motorcycles
for replacing air-polluting vehicles with combustion engines, which are driven
by
petrochemical fuel, to achieve the purpose of saving energy and reducing
carbon emissions.
As electric vehicles and motorcycles are powered by rechargeable batteries,
charging facilities
such as charging stations are of vital importance for providing battery
recharge. Actually, at
the moment batteries of electric vehicles may be recharged only in charging
stations.
[0003] When a battery of a conventional electric vehicle or motorcycle has run
out of
power, the battery protection circuit will cut off power supply straightaway,
causing the
moving electric vehicle or motorcycle to come to an abrupt stop and get out of
control due to
instant power failure. Therefore, when a battery is running out of power and
the nearest
battery swapping station is too far away, the driver may feel panic or an
accident may be
caused. Further, when an electric vehicle or motorcycle may no longer move due
to power
failure, the driver will need to resort to a cart or a crane truck for help,
which is a waste of
time and money. Therefore, the technology of extending the run time of power
supply is
essential for the popularization of electric vehicles and motorcycles. In view
of this, after
laborious research and experiments, the applicant has devised a smart charge
and power
supply device for vehicles and motorcycles which provides increased efficiency
by extending
the run time of power supply.

SUMMARY OF THE INVENTION
[0004] It is a main objective of this invention to provide a smart charge and
power supply
device for vehicles and motorcycles which provides increased efficiency by
extending the run
time of power supply through the operation of having a first battery and a

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Please refer to Figure 1 and Figures 2 to 3, illustrating
respectively a
three-dimensional view and structural drawings of the invention. As the
figures show, the
invention comprises a transmission 1, a power generator 2 having a free wheel
21, a first
battery 3, a second battery 4, a first switching mechanism 5, and a second
switching
mechanism 6, wherein the transmission 1 is pivotally connected to a
transmission mechanism
7 of a vehicle or motorcycle with a transmission shaft 11 for driving the
transmission
mechanism 7 to make the vehicle or motorcycle move.
[0013] The power generator 2 is pivotally connected to the transmission
shaft 11 with a
support shaft 22 so that the pivotally connected free wheel 21 is driven by
the transmission 1.
With its characteristic of storing rotational energy, the free wheel then
drives the power
generator 2 to generate power.
[0014] The first battery 3 and the second battery 4 are separately connected
to the first
switching mechanism 5 and the second switching mechanism 6, connecting to the
transmission 1 through the first switching mechanism 5 and to the power
generator 2 through
the switching mechanism 6.
[0015] The first battery 3, the second battery 4, the first switching
mechanism 5, and the
second switching mechanism 6 are separately connected to a control circuit 8,
which detects
the capacity of the first battery 3 and the second battery 4 and controls the
switching operation

CA 3070686 2020-02-03
of the first switching mechanism 5 and the second switching mechanism 6
according to the
detected capacity so that the first battery 3 and the second battery 4 may
alternate between
= supplying power and being charged.
[0016] The foregoing components are combined to form a smart charge and power
supply
device for vehicles and motorcycles. The transmission 1 is provided for
driving the
transmission mechanism 7 of an electric vehicle or motorcycle through the
transmission shaft
11 to make the vehicle or motorcycle move. The free wheel 21 is driven through
the support
shaft 21. With its characteristic of storing rotational energy the free wheel
21 has a reduced
fluctuation of rotational speed and therefore has smooth rotational movements,
which may
improve the efficiency of the power generator 2 in generating power to charge
the first battery
3 or the second battery 4. The first switching mechanism 5 and the second
switching
mechanism 6 are provided for switching between having one of the first battery
3 and the
second battery 4 supply power and charging the other, having a fully-charged
battery provide
power to the transmission 1 for driving the vehicle or motorcycle and having
the power
generator 2 charge a weak battery. With the foregoing operation of' having the
first battery 3
and the second battery 4 alternate between supplying power and being charged,
this invention
may achieve the objective of extending the run time of power supply and
increasing the
efficiency of electric vehicles and motorcycles.
[0017] Please
refer to Figure 4, illustrating a view of the invention in operation. As the
figure shows, when the invention is in operation, the transmission 1 drives
the transmission
mechanism 7 of an electric vehicle or motorcycle through the transmission
shaft 11 to make
the vehicle or motorcycle move, and meanwhile through the support shaft 21 the
transmission
1 drives the free wheel 21, whose characteristic of storing rotational energy
improves the
efficiency of the power generator 2 in generating power. In the present
embodiment, the
second battery 4 is providing power to the transmission 1, while the first
battery 3 is being
charged by the power generator 2. The control circuit 8 constantly detects the
capacity of the
first battery 3 and the second battery 4. When the capacity of the second
battery 4 is down to a
low point, the control circuit 8 drives the first switching mechanism 5 and
the second
switching mechanism 6 to have the first battery 3 switched to provide power to
the
4
CA 3070686 2020-02-03
transmission 1, and at the same time have the second battery 4 switched to be
charged by the
power generator 2. With the foregoing operation of having the first battery 3
and the second
battery 4 alternate between supplying power and being charged, this invention
may achieve
the objective of extending the run time of power supply and increase the
efficiency of electric
vehicles and motorcycles.
[0018] Please
refer to Figure 5, illustrating another view of the invention in operation. As
the figure shows, when the first battery 3 is providing power to the
transmission 1, the second
battery 4 is being charged by the power generator 2. The control circuit 8
constantly detects
the capacity of the first battery 3 and the second battery 4. When the
capacity of the first
battery 3 is down to a low point, the control circuit 8 drives the first
switching mechanism 5
and the second switching mechanism 6 to have the second battery 4 switched to
provide
power to the transmission 1, and at the same time have the first battery 3
switched to be
charged by the power generator 2. With the foregoing operation of having the
first battery 3
and the second battery 4 alternate between supplying power and being charged,
this invention
may achieve the objective of extending the run time of power supply and
increasing the
efficiency of electric vehicles and motorcycles.
[0019] The foregoing preferred embodiments of this invention are illustrated

invention rather than limiting of this invention. It is intended to cover
various modifications
and changes included within the spirit and scope of the appended claims, the
scope of which
should be accorded the broadest interpretation so as to encompass all such
modifications and
similar structures.
[0020] In view of the foregoing, this invention is a smart charge and power
supply device
for vehicles and motorcycles including a power generator having a free wheel,
a first battery,
a second battery, a first switching mechanism, and a second switching
mechanism. By having
the first battery and the second battery alternate between supplying power and
being charged,
this invention may achieve the objective of extending the run time of power
supply and
increasing the efficiency of electric vehicles and motorcycles.
