, Description:TECHNICAL FIELD
Embodiments disclosed herein relate to energy generation systems and methods in vehicles and more particularly to generating energy in vehicles using vehicle vibrations.

BACKGROUND
New regulations and competitions require vehicle manufacturers to increase fuel efficiency and decrease exhaust gas emission. An existing solution discloses use of recovering energy from a braking action. However, this can be inefficient at low speeds and can be costly. Another solution uses alternative energy sources (such as solar energy) for charging batteries present in the vehicle; however, the sun is required for charging and there is also an increase in weight.

OBJECTS
The principal object of embodiments herein is to disclose methods and systems for energy recovery in vehicles, which comprises of generating electricity from vehicle vibrations.
Another object of the embodiments herein is to disclose methods and systems for charging batteries in vehicles using electricity generated from vehicle vibrations.

DETAILED DESCRIPTION
The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
The embodiments herein disclose methods and systems for energy recovery in vehicles, which comprises of generating electricity from vehicle vibrations. Referring now to the drawings, and more particularly to FIGS. 1 through 2, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.
The vehicle as described herein can be a vehicle which undergoes vibrations and comprises at least one battery for storing energy, such as vehicles powered by at least one of humans, internal combustion engines, electric vehicles, alternative energy sources, and so on. Examples of the vehicles can be, but not limited to, cars, buses, trucks, scooters, motorcycles, farm vehicles, and so on.
Embodiments herein disclose methods and systems for energy recovery in vehicles, which comprises of generating electricity from vehicle vibrations. Embodiments herein also disclose methods and systems for charging batteries in vehicles using electricity generated from vehicle vibrations.
FIGs. 1a, 1b and 1c depict the energy generation module. The EGM 101 can be of a cylindrical shape, as depicted in FIG. 1a. The EGM 101 can comprise of two portions, a first portion 102 and a second portion 103. The first portion 102 can comprise of at least one piezoelectric crystal 104 and the second portion 103 can comprise of at least one rod 105 arranged such that its axis aligns with the piezoelectric crystal. The number of piezoelectric crystals 104 and the rods 105 can be identical, such that each rod 105 can align with each piezoelectric crystal 104. In an embodiment herein, the rods 105 can be metallic. In an example herein, the first portion 102 can comprise of four piezoelectric crystals 104 (as depicted in FIG. 1b) and the bottom portion 103 can comprise of four corresponding rods 105 (as depicted in Fig. 1c).
A first end of the EGM 101 can be connected to the top portion of a suspension component of the vehicle. A second end of the EGM 101 can be connected to the bottom portion of the suspension component of the vehicle.
FIG. 2 depicts a system for generating electricity from vehicle vibrations. The system 200, as depicted comprises of an energy generation module (EGM) 101, a suspension component 201, and at least one battery 202. The EGM 101 can be connected to at least one suspension component 201 present in the vehicle. In an embodiment herein, the suspension component 201 can be a shock absorber of the vehicle. In an embodiment herein, the suspension component 201 can be a telescopic fork present in the vehicle. The EGM 101 can be connected to the battery, such that the energy generated by the EGM 101 can be used to charge the battery 103.
The motion of the suspension component 201 can be transferred to the EGM 101. The EGM 101 can be actuated such that the first portion 102 and the second portion 103 move in relation to each other, based on the motion of the suspension component 201. The rods 105 can move towards the piezoelectric crystals 104, exerting pressure on the crystals 104, thereby generating electricity. The generated electricity can be used to charge the battery 202.
Consider an example where the piezoelectric crystals 104 can have a circular shape of 24 mm in diameter and 3 mm thick. Consider that the vehicle has 1000kg sprung weight. When the vehicle is moving, each suspension gets an average force of 250 Kg, while considering that the EGM 101 is connected to at least one shock absorber present in the vehicle. Also, consider that the shock absorber vibrates on average with 50 strokes per minute. For a static vehicle, the average travel of the shock absorbers is 80 mm from unladen to laden condition. Therefore the mechanical energy is 200J. The electrical energy generates can be determined using the equation (1) as 218 microjoules.
E_e=(1.08E_m+2.55)*?10?^(-6) (1)
In an embodiment herein, the EGM 101 can be connected to at least one accessory/module present in the vehicle, wherein the electricity generated by the EGM 101 can be provided to the connected accessory/module.
The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.
