SYSTEM AND METHOD FOR CHARGING A BACK-UP BATTERY OF A RUNNING TWO-WHEELER WITH WIND TURBINE

Abstract

The present invention relates to a system and method for charging battery of a running two-wheeler with wind turbine unit. The two-wheeler is run by a first battery B1 and as the speed of the running vehicle increases, the channelized air from the air vent (5) via a Y-shaped channel (24) strikes the turbine (18). The turbine (18) starts rotating, and this rotation of the turbine (18) is used to charge a back-up or a second battery B2 (17). When the charge of the first battery (16) goes beyond a minimum level, an automatic switching module in the BMS (Battery Management System) changes the power source from the first battery (16) to the second battery (17). This process continues, allowing the user to move freely on the road without frequently stopping to charge the battery now and then. Using this innovative design and power through wind energy to charge a battery, it is just needed to charge the battery once in a home or a parking space using electricity, and then when running on the road, wind energy will be mainly used to charge the battery.

A First Battery B1 (16), in the explanation of the above components, is used to start a two-wheeler by running the electric motor (10) fitted in the two-wheeler. When the two-wheeler gains the minimum speed of 30-40 km/h, the air from the vents (5) starts getting momentum, and this air is channelized to move to another vent under the seat, i.e., the air vent receiver (8).
As the speed increases, the turbine (18) starts rotating, and this rotation of the turbine (18) is used to charge a second battery B2 (17). When the charge of the first battery (16) goes beyond a minimum level, an automatic switching module in the BMS (Battery Management System) changes the power source from the first battery (16) to the second battery (17). This process continues, allowing the user to move freely on the road without frequently stopping to charge the battery now and then. Using this innovative design and power through wind energy to charge a battery, it is just needed to charge the battery once in a home or a parking space using electricity, and then when running on the road, wind energy will be mainly used to charge the battery.
Figure 1a shows the proposed invention with the front air vents (5) for receiving air. They can be cone or pyramid shaped as illustrated in figure 1b. The front air vents (5) receive the air with pressure when a vehicle (two-wheeler) moves at a speed greater than 30km/h, and these vents (5) provide the air a passage to strike the turbine (18) as shown in the Figure 2. The air coming in through front vents (5) gets pressurised in the channel (24) located inside the front portion of the two-wheeler and then this air again goes through a Y- shaped channel. As this channel is fully closed and properly channelised so the whole air coming from the front two vents (5) gets properly channelised into the air receiver (8) and moves the turbine (18).
Figure 2 shows the various components of the two-wheeler for the utilization of the innovative idea to increase the efficiency of an EV. As the flow of air from the front vents (5) take at speed greater than 30 km per hour, the wind turbine (18) moves, and the wind turbine rotation is used to charge the second battery B2 (17) while the first battery B1 (16) is used for running the motor of the two-wheeler.
Figure 3 shows the schematic diagram of an Archimedes Turbine (18). It is a turbine which converts the deficient speed of air, i.e., approximately 5m/s, to electricity, and with an average speed of the two-wheeler or bike of 40 to 50 km per hour, can be utilized to generate electricity.
Figure 4 shows the battery system (15) with the batteries (B1, B2) and the generator (21). Movement of the turbine (18) is used to generate electricity which is stored in the battery system (15) which has both a first and second battery (B1, B2) as well as a BMS circuit which switches the power source for the motor from the first battery (B1) to the second battery (B2) when the power in first battery (B1) level gets below specified, i.e., below 20%.
Figure 5(a, b)-6 show the motor (10), and gear system (19) attached to a belt (13) which is used to run the vehicle (two-wheeler). The charge from the battery (B1) is utilized to run the motor (10), and the rotatory motion of the motor (10) is transferred to the belts (13) attached to the rear wheel (3), which in turn is used to run the two-wheeler.
In case of Conventional Electric Vehicle, the electric motor takes power from the battery, which is charged through a cable, or sometimes regenerative braking is used to generate some energy, which cannot improve the efficiency so much that we do not need to charge on the go for long rides.
In the proposed invention, using the wind energy, i.e., the pressurized airflow through the front air vents (5), and then using this pressurized air to rotate the turbine (18), which in turn charges the second battery (B2) as the first battery (B1) is used to run the vehicle and when the charge in the first battery (B1) goes beyond a particular set level let's say below 20%, in that case, BMS (15) comes into play and switches the power source from the first battery (B1) to the second battery (B2) and when this second battery (B2) is used to run the two-wheeler then the first battery (B1) is charged through the same process that is the rotation of the turbine (18) through the wind generated through the movement of the two-wheeler as shown in the figures.
The motor (10), and gear system (19) attached to the belt (13) are attached to the rear wheel and are used to run the vehicle (Scooty). The charge from the batteries (16, 17) is utilized to run the motor (10), and the rotatory motion of the motor (10) is transferred to the gears (19), which in turn is used to run the scooty.
Figure 7 shows the Battery Management System (BMS) (15), which manages the electronics of a rechargeable battery, whether a cell or a battery pack, thus becomes a crucial factor in ensuring electric vehicle safety. It safeguards both the user and the battery by ensuring that the cell operates within its safe operating parameters. It slows down the vehicle when it gets overheated to prevent damage. Also, it helps shift the first battery B1 to the second B2, and vice versa. The electric vehicle transmission systems consist of a motor, inverter, controller, battery, spur gear and carbon fibre belts play a major role in the overall working mechanism. Here there is a spur gear (19) is added in between the transmission between the belt (13) and motor (10), which produces better torque.
The air passes through the vents (5) created in front of the deck frames (20). As the speed of vehicles increases to 25 m/s the Archimedes turbine (18) present in the deck/support (9) starts rotating. The turbine (18) is connected to the generator (21) in series. The generator (21) comprises of carbon brushes which on rotation of turbine (18) starts generating electricity. This electricity is passed through the battery management system (15) which regulate and transfer a certain amount of power which is required for charging of a second battery (B2) which is not working. As the charging of the previously discharged battery (B1) is completed a sensor indicates it on meter. The user can switch between batteries using a switch (6) and the fully charged battery (B2) will start working as the primary source of power while the discharged battery (first battery B1) will start charging.
When a 3-phase input is given to the stator (22), it creates a rotating magnetic field and hence induces a current in the rotor (10), and it starts rotating. The speed of induction motor depends on the frequency of the AC supply by changing the frequency of power supply, the speed of the drive can be changed. This EV uses two stage transmission because it produces more torque and can easily climb up on inclines, which is tough for single-step transmission system.
The present invention shows the two-stage transmission system. Rated voltage: 60V Top Speed: 80 km/h Rated current: 20-23A Torque: 26 Nm.
The novel and the inventive part of the invention are as follows:
Firstly, The Design-It is the most novel and inventive part of the invention. The aim of the invention is to convert the kinetic energy of the wind into the source of charge of the battery for EVs on the go so we can increase the efficiency of the two scooty/scooter or bike, or any two-wheeler designed on the proposed technical features.
In this invention a channelized source for the flow of air in the front portion of the scooty/bike has been generated which provides a proper channel to air passing through theses vents so that air directly fall on the blades of turbine and these vents have nozzle-like structure, as illustrated in figure 1b, which increases the pressure of the air flowing through these vents and hence the kinetic energy of air increases which in turn increases the rotation of the turbine fans fitted just behind the seat of the scooty.
Secondly- The switching technology between one battery (B1) on which the bike runs or scooty runs to another battery(B2) which is getting charged due to rotation of the turbine.
To make this possible an electrical sensor is used in the BMS (Battery Management system) which tracks the level of charge in the main battery (B1) and there a certain minimum level of charge is fixed for eg-5% for the main battery (B1). When charge drops to 5% the sensor will change the source of charge from (B1) to (B2) which is being charged by rotation of the turbine by the kinetic energy of wind.
As seen in the figures both the batteries (B1, B2) are combined in one with the help of a battery management system.
Thirdly, proper utilization of air flow or proper flow of air is ensured. An air passing by the bike or two-wheeler is utilized to flow into the proper channel and then the high-pressure air is used to rotate the turbine and then flow out through exhaust vent smoothly giving much resistance to the two-wheeler or the bike.
The technical advancements achieved by the present invention:
Incorporation of additional battery to increase the efficiency of two-wheeler by 30-40 %. Reducing the charging time as one battery constantly gets charged when the vehicle is moving.
