Description

"ASSEMBLY, ELECTRIC POWER GENERATOR BUILT IN WHEEL (S) OF PURE, HYBRID, VEHICLE ENGINE CELLS, OR ANY OTHER AUTOMOTIVE TECHNOLOGIES WHICH PROTECTOR USES A PROTECTOR WHICH VEHICLE ROLLING AUTONOMY "

The present invention relates to a simple, inexpensive power generator set mounted within one or more wheels of any type of automotive electric vehicle, such as automobiles, vans, utilities, buses, trucks, and others, whether they are pure pollutant-free electric vehicles, hybrid electric vehicles, or any other technologies that use electric motors as a propulsion in their design, which can be installed in any mechanical and / or auto-electric workshop, or already factory installed on new electric vehicles (OKM), which requires little or no maintenance in their later operation. This generator set, which will be detailed below, is internally composed of a stator element fixed to the external housing of the generator, which in turn is fixed to the vehicle suspension, a rotor element fixed to the wheel rotation axis, as well as their respective windings. with or without brushless brushes. Also part of the generator set is an external power control and load balancing circuit between the electric motor of the vehicle and its battery bank, or fuel cell, having external computer output, aiming to perform tests and calibration after the installation of the generator set, technical assistance and maintenance if necessary, as well as all other functions that require electrical and / or electronic control, acting as a microprocessor digital electronic central, which will be sufficiently detailed throughout this description. The generator set can be manufactured in various models depending on the voltage and power required by the electric motor used in each vehicle, for the additional charging of electric energy from the batteries in balance with the energy supplied to the electric motor, aiming to further increase the autonomy of the vehicle. , which will also be all described in detail later.

World panorama - It is known that in view of the enormous consequences that the The continuous emission of pollutant gases into our atmosphere, mainly from the burning of fossil fuels in today's fuel vehicles, sets an imperative impetus for 21st century science and technology. Energy, security, national security, environmental security and economic security will probably only be achieved by focusing on the energy problem in the coming decades.

The secret lies in the development of new clean technologies (free from the emission of noxious gases) that can integrate viably and economically with existing technologies, thus enabling their mass adoption by the population, as the technology that will be described at length below. , object of the present invention patent registration, fruit of many years of research of its inventors.

The state-of-the-art on the planet regarding this type of research is driven by the world's largest automakers, whose current focus is on the production of new Hybrid vehicles powered by traditional fossil fuels and / or electric motors. These same automakers today do not have any product advertised as the present electric generator set, which aims to increase the autonomy of electric vehicles, whether they are pure, hybrid or fuel cell electric vehicles, as the generator object of this patent. invention.

Hybrid models - With two engines, one petrol and one electric, it is a slightly cleaner and more economical machine than any of the models produced so far. It averages 28 kilometers on one liter of gasoline, emits slightly less carbon dioxide and one tenth of the other pollutants tolerated by stricter environmental laws. This is possible thanks to a computerized electronic control unit that controls both a gasoline engine and an electric engine, a system called a hybrid. Typically, 58 horsepower from a 1.5-liter gasoline engine and 23 horsepower from the electric motor use the charge of a set of nickel metal hydride batteries located between the rear seat and the trunk.

Pure Electric Vehicle - General Motors, for example, launched in 1997 the two-seater EV1, powered by an electric motor powered by 26 lead-acid batteries, similar to today's cars. In the same year, Honda began selling the four-seater Honda EV Plus in California and Japan. Unified Europe has also set its environmental protection goals, which has led Renault, Citroèn-Peugeot and Fiat to launch electric cars. And to compensate for the Seicento's only 90 km range, Fiat has set up the Eco Parking in Turin: the user leaves his car in a parking lot and rides around the historic city center with an experimental electric model. Recently, the Italian factory brought the idea to Curitiba and intends to create soon another parking lot of the same type in Belo Horizonte. However, it is not yet known that any of these companies are harnessing the rotational kinetic energy of their vehicle wheels to generate additional electrical power and to power both the moving vehicle's electric motor as well as to balance the charge of the battery bank, as the present invention is the subject matter of this patent application.

It is the object of the present invention to provide an electric power generator assembly mounted within the wheel (s) of an electric vehicle, internally composed of a stator element attached to the external housing of the generator, which in turn is fixed to the vehicle suspension means a rotor element fixed to the wheel's axis of rotation, as well as their respective electrical windings with or without brushless brushes, stator and rotor locking rings, calipers, bearings, and other mechanical devices. Also part of the generator set is an external power control and load balancing circuit between the electric motor of the vehicle and its battery bank, having external computer output for testing and calibration after the installation of the generator set, technical assistance and maintenance as necessary, as well as all other functions requiring electrical and electronic control, acting as a microprocessor-based digital switchboard responsible, among other purposes, for balancing the voltage and amperage of the battery bank and the electric motor that drives the vehicle, control the state of the controller's digital electronic circuitry, as well as the messages from the internal microprocessor to the electric vehicle's general control center, indicating which devices are operating at any given moment, and the warning signals that indicate any failures.

The electric generator set according to the present invention is further explained by the accompanying drawings in which Figure 1 schematically shows, in a simplified manner, the operation of a electric power generator for the purpose of powering the vehicle's electric motor, as well as replenishing the battery charge and supplying power to the other electrical components, all consumers connected to the generator, while also maintaining the load balance during the operation of the electric motor, that drives the vehicle. Fig. 1 illustrates the stator assembly (1) attached to the vehicle suspension frame and chassis with only two magnetic poles (2) of opposite magnetic polarity, the movable rotor (3) attached to the moving vehicle wheel, as well as the electromagnetic force (4) resulting from the movement of the rotor (3), which induces by magnetic effect an electric current in the stator windings (1). This is the simple principle that enables the generation of electrical energy from the movement of the vehicle's wheels, inducing an alternating electric current, with frequency proportional to the wheel's rotation speed.

Fig. 2 illustrates the 12-pole stator assembly (1) used in the generator object of this patent application, three-phase with its four sets of electromagnetic-offset windings 120 ° apart in sequence ACB-ACB-ACB-ACB , each set A, B and C with their respective north (N) and south (S) magnetic poles in mechanical opposition. The rotor assembly 3 is shown in the center in Fig. 2 also with its four N-S windings. The number of magnetic poles of both the stator and rotor may vary from design to design depending on the desired characteristics, which is not a limiting factor of the present patent application.

With the evolution of automotive electric vehicles has been incorporated a series of power components that increase the demand for energy consumed. With the increase of traffic in cities, with electric vehicles running at low speeds, would lead to the limits of operation and application of conventional generators (with collector), because the greater the range of rotation variation, the more difficult will be the control of the conversion of the Three-phase alternating current, produced by the generator, for direct current, to supply the required power of consumers and also charge the vehicle's battery bank.

To monitor the evolution in electric vehicles, the obtaining of direct current without the use of a collector was supplied to the system through a three-phase rectifier bridge, based on silicon semiconductor diodes, which can easily be installed on the generator due to their small size. It allows the rectification of three-phase alternating current so that the generator provides direct current. With these characteristics we can call our generator: "three-phase direct current generator, without collector, with electronic circuit voltage control and load balancing, whose system controls the rotor field excitation current in order to maintain the voltage generated in the stator within the specified limits ".

The generator thus constructed is based on the principle of electromagnetic induction to generate electrical energy, which from a conductor (a wire or loop) in the stator windings is crossed by the lines of a magnetic field generated by rotor rotation, thus a Voltage is induced in this conductor, which is independent of movement between the magnetic field and the conductor. Imagine a motionless conductor with a rotating magnetic field, if the ends of that conductor are connected to a voltmeter, you can see that the voltage will take an alternating shape due to the varying position of the loop relative to the poles. If the rotation of this loop is constant, the tension curve by position (angle of rotation) of the loop will be sinusoidal.

The term electromagnetism also includes the physical phenomenon that conductors subjected to an electric current are surrounded by a magnetic field. In the case of a coil, the strength of the generated magnetic field depends on the number of turns and the magnitude of the current flowing through it (in practice, a large number of turns is used, also known as armature). This magnetic field can be enlarged with the use of magnetizable iron cores.

The use of these principles in the generator leads to the fact that the intensity of the magnetic field can be increased or reduced and thus increased or reduced the induced voltage. When the excitation current of an electromagnet stops circulating, the magnetic field of its turns also extinguishes, except for a small residual portion. The excitation current may come from an external power source, for example from the battery or from the generator's own electrical circuit. An advantage of three-phase current is that it allows the most efficient use of generator potential.

In the generator shown in Fig. 2, there are three identical coils (A, C, B), mechanically arranged at 120 ° from each other. In accordance with the principle of induction, as the rotor (3) rotates, three alternating currents of the same frequency and magnitude are generated, but are offset by 120 ° in the stator (1). These three currents are called three-phase alternating current. Normally, a generator would need six wires to conduct the induced current in the three coils. However, it is possible to reduce the number of connections to three by connecting the coils together. There are two possible ways to make this connection: triangle or star.

In our generator, it has been proven to be more advantageous to house this arrangement of coils in the stationary part of the equipment, also called stator (1). The poles of the magnet, which is crossed by the excitation current, are in the moving part of the equipment or rotor (3). This excitation current is a pulsating direct current that generates a magnetic field in the rotor armature (3), which in turn induces a three phase alternating current in the stator (1).

Fig. 3 illustrates the three-phase alternating current (3) generated by the power generator object of the present patent application, which has the disadvantage that it cannot be stored in the battery, and is not suitable for powering the electrical components either. and vehicle electronics as well as its electric motor. To perform this power supply it is first necessary to rectify the current. This rectification is made through the semiconductor diodes shown in Fig. 3 (1) in triangle or star connection, with equivalent electrical circuit (2). The rectifier diode allows the current to flow only in one direction (in the direction of the arrow of the diode symbol), ie it only allows the passage of the positive "half waves" as illustrated in Fig.3 (4), whose result is a pulsating direct current. In the rectification of three phase systems, this method is applied in each of the phases. In order to take advantage of all "half waves", including negative ones, it is necessary to use two diodes per phase: one diode on the positive side and one on the negative side as shown in Fig. 3 (2). This circuit, called a bridge, provides full wave rectification. The result of rectification is the sum of the positive and negative amplitudes of the three-phase current (4). This sum generates a direct current (5) with a certain ripple noise factor. These fluctuations in current can be smoothed out by the battery and capacitors that are connected in parallel with the generator. The excitation current, which has the task of magnetizing the rotor armature poles, comes from the three-phase circuit and also undergoes a rectification. full wave before feeding the armor. This rectification is performed with the aid of the excitation diodes. The generator rectifier diodes not only rectify the excitation current and the current that powers the vehicle's electrical and electronic components, but also prevent the battery from discharging through the three stator coils.

O There are three internal circuits in the generator:

- Pre-excitation circuit;

- excitation circuit (self-excitation), and

- Voltage regulator circuit.

PRE-EXCITEMENT CIRCUIT

Current from the battery bank pre-excites the generator. Pre-excitation is necessary, as in generators, residual magnetism in the iron core is not sufficient at the time of starting. Therefore, the generator is not capable of generating a sufficient magnetic field, and consequently generating the required voltage. In the excitation circuit there is an excitation diode and a power diode in series for each of the phases. Therefore, self-excitation only begins after the generator can generate a voltage greater than at least the voltage drop in both diodes (2 x 0.7 V = 1.4 V). When the wheel of the electric vehicle begins to spin, the flowing current must be large enough to generate a magnetic field capable of initiating the self-excitation process.

EXCITING CIRCUIT

The function of the excitation circuit is to produce a magnetic field in the rotor and thus induce the required voltage across the three stator coils during the entire operating time. Part of the stator current flows to the battery and loads, and part to the regulator and rotor. When the excitation circuit begins to operate (when the warning lamp goes out), the voltage generated in the stator is still too small to feed the loads, so the current flow happens only in the self-excitation circuit. The rotor is powered by the stator and induces a higher voltage than the previous one. This cycle repeats until the induced voltage in the stator is sufficient to drive the main circuit diodes to power, and power the batteries and other loads present in the vehicle. At this point, the regulator prevents the generated voltage from increasing further. Fig.4 illustrates the basic parts of the generator inside the wheel: - Stator inside the wheel (3): consists of three windings (12 poles), arranged at 120 ° from each other;

- Rotor inside wheel (4): is the moving part of the generator coupled to the wheel of the electric vehicle. It has an axis that carries the electromagnet, the rings (6) and collectors, through which the current circulates;

- Internal wheel fan (5): also connected to the rotor shaft, serves to cool the generator.

- Rectifier: has six power diodes and three excitation diodes, which convert three-phase current into direct current;

- Regulator: also mounted inside the generator housing, serves to regulate the generated voltage;

- Rings and collectors (6 and 7): The rings are fixed to the electromagnet poles, while the collectors are pressed against the rings. They serve to protect and secure the internal parts of the generator. Fig. 4 also illustrates parts of the vehicle suspension (1), the attachment of the generator set to the disc (2) and the brake pad calipers (8), finalizing the attachment to the wheel (5) of the electric vehicle.

VOLTAGE REGULATOR CIRCUIT

The function of the regulator, also mounted internally within the generator housing, is to maintain constant the voltage generated for all vehicle operating speed fields reflected in its wheels. Automatic voltage regulation is not a simple task as the vehicle engine constantly changes speed. In addition, many of the vehicle's electrical and electronic devices are switched on for a brief period of time, or manually operated. Therefore, the load that the generator must supply is not constant. When the engine is running at a high speed and there are few loads to be fed, it must be ensured that the voltage is limited to a preset value, usually the value of the battery bank "Tricker Point".

This protects the devices from overloads. In addition, it should be noted that the electrochemical properties of batteries vary with temperature. Therefore, a higher voltage should be generated on cold days.

The voltage generated by the generator increases with both its rotation and magnetic field strength due to the excitation current. If a generator were to operate under maximum excitation current, with no connected loads, the voltage would increase linearly with its axis rotation speed. The principle of voltage regulation is based on the regulation of the excitation current, which in turn regulates the magnetic field of the rotor. The regulator starts when the voltage generated exceeds the preset value. It interrupts the excitation current, causing the rotor's magnetic field to decrease. When the voltage drops below the preset value, the generator excitation starts again and the cycle repeats, this occurs very fast (in milliseconds). Despite this switching on the current, it does not fall or rise abruptly. This is because the winding present on the rotor is a large inductive load. Therefore, its magnetic field generates a counter electromotive force when the current tends to vary, smoothing out the current variation. Generator regulators have the function of controlling voltage only. This is due to the fact that the function of the shunt relay is exerted by the diodes, and current limitation is unnecessary, since from a given rotation the current reaches a maximum value, so it is said that the generators are self-limiting.
