FIELD OF INVENTION

The invention generally relates to Energy Generation and Management system & more specifically to the energy generation and management of electric vehicles which are on board drive and consume energy from energy storage within the batteries, reduces the sizing of battery banks, the batteries get less drain & bypass during on-board drive, removes regular external charging & are having longer life & are economical.

BACK GROUND OF INVENTION

As a result of the fossil fuel crisis and increase C02 emission in atmosphere, switching to alternate of source of energy have recently attracted greater interest.

Vehicle pollution (also transport pollution, motor pollution) is the introduction of harmful material into the environment by motor vehicles. These materials, known as pollutants, have several bad effects on human health and the ecosystem. Examples of such pollutants include Carbon monoxide, Hydrogen, Nitrogen Oxide, particulate matter, Ammonia and Sulphur Dioxide. Transportation is a major source of air pollution in many countries around the world due to the high number of vehicles that are available on the roads today. An increase in purchasing power means that more people can now afford cars and this is bad for the environment. Vehicles introduce toxic materials into the atmosphere through different ways. Given that they are machines, they emit several substances as waste products, and these substances are the ones that cause environmental pollution. Vehicles using both electric motors and internal combustion engines are examples of hybrid electric vehicles, and are not considered pure or all- electric vehicles because they cannot be externally charged (operate in charge-sustaining mode) and instead they are continually recharged with power from the internal combustion engine (ICE) and regenerative braking.

Hybrid vehicles with batteries that can be charged externally to displace some or all of their internal combustion engine power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and run as BEVs during their charge-depleting mode. PHEVs with a series power train are also called range-extended electric vehicle electric vehicles and conventional internal combustion engine vehicles, to one of the two categories. Plug-in electric vehicles, together with hybrid electric vehicles are called new energy vehicles (NEVs)

The concept of battery electric vehicles is to use charged batteries on board vehicles for propulsion.

SUMMARY OF INVENTION

TECHNICAL PROBLEM

As a result of the fossil fuel crisis and increase C02 emission in atmosphere, switching to alternate of source of energy have recently attracted greater interest. Vehicle pollution (also transport pollution, motor pollution) is the introduction of harmful material into the environment by motor vehicles. These materials, known as pollutants includes Carbon monoxide, Hydrogen, Nitrogen Oxide, particulate matter, Ammonia and Sulphur Dioxide, have several bad effects on human health and the ecosystem.

An electric car propelled by one or more electric motors, using energy stored in batteries. The battery banks are normally to on board drive around sized for Kilometers driving requires in single charge, the charging take around 3 -10 hours to recharge, depending on batteries sizing, the life reduces to rated cycles.

TECHNICAL SOLUITON

Electric Vehicles usually also show significantly reduced greenhouse gas emissions, depending on the method used for electricity generation to charge the batteries, battery electric do not produce C02 emissions at all, but only if their energy comes from renewable electricity or low carbon sources like nuclear.

Energy generation and management system of electric vehicles which are on board drive, makes it zero carbon emission vehicles with reduction in battery bank sizing less than ½ the rated power required by front and rear wheels.

The Energy Generation are using wind energy & solar perovskite cells. The self- generation of energy using dynamo geared with motors during onboard will bypass batteries will require zero energy from batteries, remove regular external battery charging.

The wind energy used during onboard to generate energy, controls and maintains the battery banks from very low drain cycle, controls temperature of battery bank, increase the life of battery bank & maintains temperature of motors and dynamo using thermoelectric cooling and heating.

The energy generated from wind energy will maintain climatic control of air using Thermoelectric cooling & heating & Phase Change Material.

The Electrical Generation & Management system can be installed in new electrical vehicles and retrofit within existing electric vehicle & conversions of hybrid electric vehicles of all conventional internal combustion engine vehicles, zero carbon emission vehicles have zero expenses on electrical battery charging.

Hereinafter, a configuration of operation of an exemplary embodiment of the Present invention will be described in details with reference to accompany Figures.

Figure 1 illustrate Electrical Generation & Management of Electrical Vehicles (EV) (2, 3, 4 wheeler), EV (four wheels 1, 2, 3, 4) geared with front (1, 3) and rear (2, 4) wheels driven by BLDC motors. Each wheel is geared with a Brushless DC (BLDC) motor (20, 24, 9, 12) & dynamo (21, 25, 8, 11) using bevel gear box.

The wheels (1, 3) are powered from battery bank (5) and wheels (2, 4) are powered from battery bank (6) for few minutes for first on-board drive.

Before onboard drive of electrical vehicles for the battery bank (5, 6,) are fully charged from external battery charging station. Further the battery bank (5,6) are charge maintaining low drain, maximum of (10%) between duty cycle 100-90%, controlled by wind energy generated from wind energy wheel (13) coupled with flywheel(14) to maintain steady output rpm which drive dynamo (14-a)with constant output , regulated controlled power(19) to battery bank (15). The battery bank(15) output is given to controller Variable Speed drive(26) to BLDC motor(16) geared with dynamo (17) to controller (18), which provides changing to battery bank (5,6) to drain less than 10%, (100-90% duty cycle) and energy required for plug in load within electrical vehicle during on board drive. The wind energy is sized depending on the maximum energy required for plugin loads (27). The wind energy wheel can be locked at 99% of charging of battery bank (15) and unlocked when the battery bank (15) is below 90%. The wind energy wheel can installed as per total sizing of electrical vehicle required.

When the electrical vehicles are on board drive, the wheel (1,3, 2, 4) utilized the power from battery bank(5, 6) for few minutes, simentenously dynamo (21, 25) start generating total electrical energy 2 time with depending on rotation per minute (rpm) for two rear wheels (2, 4) required for two wheel drive electrical vehicles with power supply to wheels (1,3, 2, 4). In four wheel drive simentenously dynamo ( 21,25,8,11) starts generating 1 times energy required by four wheels(l,3,2,4) with depending on rpm of wheel (1, 3, 2, 4) for front and rear wheels.

The electrical motor rpm geared with dynamo rpm using bevel gear box, the power required by each wheels, the dynamo rating can be selected for required time the total power generation required with the electrical vehicles. In most of electrical vehicle will required 4 time the energy required by single wheel.

Once the electrical vehicle are on board drive, first few minutes the all four wheel (1, 3, 2, and 4) get the energy form battery bank (5, 6), the dynamo (21,25) geared with bevel gear box will generate 4 (2+2) times (2x ,2x) the energy required by each wheel motor(l,2,3,4) ,of total 4x energy generated, 2x (x+x) feedback to motor (20,9) geared with wheel (l,2)and other 2x(x+x) feedback to motor (24,12) geared with wheel(3,4). The battery bank (5) is in parallel to motor (20, 24) which maintains all time the required power to wheel (1, 2). The battery bank (6) is in parallel to motor (9, 12) which maintains all time the required power to wheel (2, 4). The rpm of wheels (1, 2, 3, and 4) are same rpm for dynamo with maximum twice the gear ratio. The energy generated maximum of 2x for each dynamo in two wheel drive and lx for each drive four wheel drive. Once the self-generation of energy using dynamo geared with motors during onboard will bypass batteries will require zero energy from batteries. The Electrical Generation & Management system, will remove the external charging. The electrical vehicle is zero carbon vehicle (Figure 1).
