An objective of the present invention is to eliminate vehicle range anxiety of the users by providing an onboard system and method for charging of the electric vehicle, wherein the onboard system comprises a pair of batteries, keeping one of the batteries for continuous charging by the system and utilizing the other battery for driving the vehicle. Another objective of my invention is to provide an onboard system and method for charging of the electric vehicle, which is economical, light-weight and easy to implement for new as well as existing vehicles. Another objective of my invention is to provide an onboard system and method for charging of the electric vehicle, which eliminates the dependency of external source (such as charging station) for charging of the electric vehicle The system may comprise a pair of batteries, one or more hub motors and Electric Ducted Fans (EDF). the batteries may be selected as Lithium Iron Phosphate batteries, the EV utilizes first battery for driving the EV, while the second battery gets charged simultaneously. The EV is driven through the hub motors. The hub motor (also referred as wheel motor) is an electric motor, incorporated into the hub of a wheel of the EV. The hub motor drives the wheel directly by utilizing the power from the battery. These hub motors can also function as a generator, converting the mechanical energy into electrical energy, when the electric motors are used in reverse manner, The primary principle of the present invention is based on Electric Ducted Fans(EDF). The EDF are capable of generating huge and massive thrust. Furthermore, the output of the EDF primarily depends on the number of blades installed over the fan and the power supply. More the number of blades, higher will be the thrust and lower will be the noise and vibrations from the EDF. Furthermore, the thrust generated from the blades of the EDF can be increased by maintaining higher pitch angle. he EDF comprises of twelve to fourteen blades and fans (similar to turbine fan of a jet engine). As the high blade pitch angle and high motor speed provide much higher thrust force for the electric vehicle to move ahead, the motor used in the EDF is axial flux motor. It is well known that the axial flux motor is the most preferred motor for generating higher thrusts. The axial motors have higher torque and are also light in weight. The axial motors provide high power to torque ratio. Also, the fan blades of these motors rotate are capable of running at high speeds and RPM, eventually generating higher thrust. Hence, the axial flux motors are usually preferred for the EVs. As regards to the functioning, the axial flux motors is pretty much similar to BLDC motors, by energizing separate windings. Hence, at certain intervals the motor is capable of generating attraction and repulsion force which makes the motor rotate. Additionally, the axial flux motors are highly efficient as they are directly connected to the shaft of the fan blades of EDF Furthermore, the thrust of EDF can be increased by installing plurality of fan blades and turbines, such that the fan blades and turbines also rotate in counter direction. For example, if the first fan blade is rotating in clockwise direction then the second fan blade and turbine will rotate in anticlockwise direction, and generating higher thrust from the EDFs. If a single EDF generates the thrust of 10 kgs, then due to installation of multiple fan blades with opposite and counter direction movement, the multiple EDFs will generate a thrust of 20 kgs. Additionally, each fan blade and turbine may be connected to a separate axial flux motor. Overall, the system is designed in such a way that as soon as the first battery is fully utilized and discharged, the power source from the first battery is disconnected and is further connected to the second battery. It can be said that, the first battery will switch to charging mode after it is discharged and the second battery will initiate the driving the vehicle. Furthermore, the hub motors will act in reverse mode, acting as a generator, generating an electric current and charge the first battery. In an embodiment, the power source from the second battery is supplied to the EDF, thereby rotating the fan blades and eventually generating thrust for driving the EV in forward direction. In this manner, the electric energy from the battery is converted into a kinetic energy of the vehicle. the working of the on-board system and method for charging the
EV is discussed as below. The system enables switching to the second battery as a power source to the EDF, when the first battery gets discharged completely. When
the EDF motor is powered through the second battery, the EDF facilitates movement 5 of the EV, instead of the hub motors. Further the hub motors will act as a generator,
generating the electric current, by utilizing kinetic energy of the vehicle for transforming into the electrical energy. Hence, the mechanical energy is instead
converted into the electrical energy and supplied to the first battery for its charging. Moreover, the EDF facilitates (as shown in figures 4a and 4b) the movement of the
vehicle through generation of the high thrust.
Furthermore, the present invention can be implemented for all types of vehicles, but not limited to, two-wheelers, cars, trucks, buses, trailers, tractors, earth movers,
aircrafts, ships, etc.
