Electric Bicycle with self-recharging Unit

FIELDOFINVENTION

The present invention generally relates to a field of automobile engineering in combination with electrical engineering. The present invention specifically relates to an electric vehicle with self-charging properties.

BACKGROUND OF THE INVENTION

The scarcity of fuel from the past few decades has been challenging to the industrial sector globally and especially to the automobile industry. Since then, there has been research in the development of alternate fuels and which has eventually led to the development of electric vehicle. An electric vehicle in common terms can be defined as a machine operating whether fully or partially on electricity. The electricity in these vehicles which are available in the market is stored in a battery which in turn drives the motor and thereby the vehicle.

For example, the hybrid electric vehicles may combine an internal combustion engine and an electric motor powered by an energy storage device, such as a traction battery, to propel the vehicle. Such a combination may increase overall fuel efficiency by enabling the combustion engine and the electric motor to each operate in respective ranges of increased efficiency. Electric motors, for example, may be efficient at accelerating from a standing start, while internal combustion engines (ICEs) may be efficient during sustained periods of constant engine operation, such as in highway driving. Having an electric motor to boost initial acceleration allows combustion engines in hybrid vehicles to be smaller and more fuel efficient.

The purely electric vehicles use stored electrical energy to power an electric motor, which propels the vehicle and may also operate auxiliary drives. Purely electric vehicles may use one or more sources of stored electrical energy. For example, a first source of stored electrical energy may be used to provide longer-lasting energy (such as a low-voltage battery) while a second source of stored electrical energy may be used to provide higher-power energy for, for example, acceleration (such as a high-voltage battery or an ultracapacitor).

The plug-in electric vehicles, whether of the hybrid electric type or of the purely electric type, are configured to use electrical energy from an external source to recharge the energy storage devices. Such vehicles may include on-road and off-road vehicles, golf carts, neighborhood electric vehicles, forklifts, and utility trucks as examples. These vehicles may use either off-board stationary battery chargers, on-board battery chargers, or a combination of off-board stationary battery chargers and on-board battery chargers to transfer electrical energy from a utility grid or renewable energy source to the vehicle's on-board traction battery. Plug-in vehicles may include circuitry and connections to facilitate the recharging of the traction battery from the utility grid or other external source, for example.

Some battery chargers are important components in the development of electric vehicles (EVs). Historically, two types of chargers for EV application are known. One is a standalone type where functionality and style can be compared to a gas station to perform rapid charging. The other is an on-board type, which would be used for slower C-rate charging from a conventional household outlet. EVs typically include energy storage devices such as low voltage batteries (for range and cruising, for example), high voltage batteries (for boost and acceleration, for example), and ultracapacitors (for boost and acceleration, for example), to name a few. Because these energy storage devices operate under different voltages and are charged differently from one another, typically each storage device includes its own unique charging system. This can lead to multiple components and charging systems because the storage devices typically cannot be charged using charging systems for other storage devices. In other words, a charging device used to charge a low-voltage battery typically cannot be used to charge an ultracapacitor or a high-voltage battery.

However, there is still the case that the fully or partially electric vehicles need to be charged first and then run. This stuff of being charging the vehicle battery is more often time consuming and the vehicle most of the times runs out of battery on the way. Therefore, there is a need to develop a system wherein a vehicle such as a bicycle can self-charge the battery while hitting the road. The present invention overcomes the limitations and disadvantages of the existing technologies by some technical advancements as will be described herein later.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Figure 1 illustrates a block diagram of components installed in a self charging electric bike. The self-charging electric bike mainly includes a main controller unit (104) which coupled to a main body (102) of said electric bike and configured to propel said electric bike, wherein said main controller (104) is configured to receive an input signal from a self-charging unit (122) in order to drive said electric bike main body (102), wherein said main body (102) comprises an accelerator (108) and a pair of brakes (110, 112) with auto-cutoff, a hand throttle with a horn (114), a pair of headlight indicators (106).

A power generating unit (116) is the main component installed herein which charges the bike while propelling or driving over a road. The said unit (116) is coupled to said main controller (104) and operatively connected to a pair of pedals (124), wherein said power generating unit (116) comprises an alternator (118) which is connected to said pair of pedals (124) via a shaft, wherein when said pair of pedals (124) rotate by providing a torque, said torque is transmitted to said alternator (118) and thereby a magnetic field is generated and due to which said alternator (118) rotates and generates electric charge.

A storage unit (120) is operatively coupled to said power generating unit (116) and said main controller (104), wherein said storage unit (120) receives said generated electric charge from said alternator (118) and stores said electric charge, wherein said storage unit (120) transmits said stored electric charge to said main controller (104) in order to propel said main body (102).

An electric motor (126) coupled to said storage unit (120) and operatively connected to said main controller unit (104), wherein said motor (126) is configured to receive said stored electric charge from said storage unit (120) via said main controller unit (104) in order to convert said electric charge into mechanical motion of wheels of said electric bike. The electric motor (126) is mainly DC motor which can propel said vehicle by receiving DC charge stored in said storage unit (120).

Figure 2 illustrates a schematic working block diagram of the main components in said self-charging electric bike. As displayed, the main objective of the present invention is to generate electric charge while driving over a road. This charge is generated by an alternator (206) which is connected to a pair of pedals (204) of the electric vehicle (202). When a user applies torque over the pedals (204), the vehicle moves, and this torque is received by the alternator (206) which thereby generates a magnetic field due to rotation and thereby due to such rotation an electric current is generated. This alternator is connected to a storage unit (208) which includes a battery which can store electric charge. The electric current from the alternator is transmitted to a conversion unit which converts said produced alternating current into a direct current which can be easily stored inside the battery of the storage unit (208). Therefore, the vehicle (202) self-charges itself while driving over the road and there is no need to charge the battery after driving some distance as in case of conventional electric vehicles.

The present invention can be better understood by some steps as; first the existing model of electric vehicle is run on the electric capacity of battery; after that a magnetic alternator is provided to generate power for the battery charging; after rotation of the alternator it generates the electricity at the rpm of near about 3000rpm and when electricity generated after that the battery provided in the vehicle is charged on the electricity which provide by the alternator; for the purpose of alternator rotation torque is provided for the same/conventional bicycle pedal operation to initially rotation of the same alternator after that due to magnetic field effect of the alternator it rotates at near about 3000rpm.

The present invention further states the alternator generates electric charge by rotating at a speed of at least 3000 rpm. When said torque is transmitted to said pair of pedals, said alternator starts generating and transmitting said electric charge to said storage unit and said main controller turns said pair of headlight indicators in on condition indicating said electric bike is in on condition.

The storage unit further comprises one or more energy storage devices coupled to said main body of said electric bike and configured to store electric charge in a form of a DC energy. A power electronic conversion system having a plurality of energy ports, wherein said power electronic conversion system comprising a plurality of DC electrical converters, with each DC electrical converter configured to step up and to step down a DC voltage. Each of said plurality of energy ports is coupled to each of said one or more energy storage devices and each of the plurality of energy ports is coupled to said power generating unit.

The self-charging electric bike further comprises a first terminal pair configured to electrically couple said storage unit to a first voltage domain. A second terminal pair configured to electrically couple said storage unit to a second voltage domain. A plurality of battery cells electrically coupled in series between a first terminal of the first terminal pair and a second terminal of the first terminal pair.

The DC motor coupled to said storage unit is configured to have at least 24 volt rated input power with an output of at least 250 watts, wherein said motor is configured to rotate at least 3300 rpm with a reduction ratio in a range of 9:78.

The main controller is configured to transmit said motor at least 24 volts in DC energy, with a tolerance of around 20 to 05 volt and on at least 21 to 1 Ampere current.

The pair of pedals are configured to initiate said alternator by providing a rotational motion to said alternator in order to generate magnetic field for sufficient electric charge generation in order to drive said electric bike. When the user applies a torque over said pedals for a specific time period, said motion is transmitted to said alternator via said shaft which in turn generates electric charge for said storage unit, and said storage unit transmits said charge to said motor via said main controller in order to drive said bike.

The present invention further states by the application of above mentioned self-charging unit in a conventional bike, there is an increase in a long-term efficiency of the bike. Moreover, there is reduction of cost due to continuous charging and repairing of the conventional bike. The time is reduced as the bike itself charges while driving over the road, therefore, is time saving.

The drawings and the forgoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, orders of processes described herein may be changed and are not limited to the manner described herein. Moreover, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts necessarily need to be performed. Also, those acts that are not dependent on other acts may be performed in parallel with the other acts. The scope of embodiments is by no means limited by these specific examples. Numerous variations, whether explicitly given in the specification or not, such as differences in structure, dimension, and use of material, are possible.
