Abstract

This invention is about advanced version of recharging battery (6) for electric car. Air resistance pressure generated when travelling a car makes the blade (2, 2-1) rotate, and this rotary force is converted into electrical energy by power generator (5) and the battery (6). The rotary force is maximized by increase in air speed through louver-type cylinder (12), interaction between electrical energy converted by coil (14) inside the cylinder and magnet (13) put on the blades (2, 2-1).

Description

Electric power generating system using the air resistance power in driving

During the past hundred years, gasoline has been used as the main source of energy in industrialized countries. With technology innovation in automobile production, research on substitute energy has also been made.

But using the air resistance pressure has been ignored for the economical reason. Research stopped on just only designing streamline shaped frame, and the technique using air resistance pressure to run the power generator inside the car was nothing better than running a windmill.

These kind of techniques are less practical, since such streamline shaped frames are hard to produce, or the latter limits capable travelling distance depending on battery capacity and charging method.

This invention is about self-rechargeable battery for electric car. It is designed to maximize the use of air resistance generated when the car travels, by converting the initial kinetic energy into electrical energy, then to the kinetic energy again. Lots of research using the air resistance as source of energy has been made so far. But none of them have been able to supply its energy 100% independently, because they didn't make full use of air resistance as the further source of energy.

To solve such problems, louver-type cylinder(12) with magnets(13) attached on the number of blades(2) inside it, is put in forepart of the frame. Additional magnet(13-l ) is attached on the induction coil(14) inside the cylinder, which will interact with magnets(13) put on the blade(2). It uses air resistance pressure, which will increase the speed due to the pressure differential. It is self-power-generating system, in which the interactions of magnets(13.13-l) will double the rotary force.

This self-rechargeable battery is designed to maximize efficiency in using air resistance as source of energy by multi-stage conversion.

The car starts with fully charged battery. As car travels, the air resistance pressure passing through the louver-type cylinder(12) makes blades attached to axe(l) rotate. So far has been the initial stage for power generation. The advanced stage of charging the battery will be explained.

The air resistance pressure gathered in the cylinder(12). which is located in forepart of the frame, made the blade(2) attached to axe(l,l-l) rotate. Permanent magnets(13-l) are attached inside the cylinder(12) in clockwise slope, and as these magnets(13-l) and the ones(13) on the blades(2) will have the same polarity(N-N, or S-S), the repulsive force generated through the rotation of axes is added to the air pressure, increasing the rotary force.

An axe( 1 - 1 )of diamagnetic substance, without permanent magnet on it, is designed to put between the magnets(13,13-l) of both on the coil(14) and at the blade(2) in the way it will not smack the blade on the axes of both side, to cut off magnetic attraction. This is to facilitate the rotation of both axes(l), for strong magnetic force will generate stronger magnetic attraction from the same polarity, which is of resistant to easier rotation of axes( 1 ) at slower speed. Namely, it makes the rotation possible even when the car starts, at which the weaker air resistance pressure is likely to be dominated by the existing stronger attraction, by setting apart the magnets(13,13-l).

As magnets with high flux density (rare-earth series) can be used to generate strong rotary force, magnetic attraction is stronger even before the car starts. So, in case when the blades(2) fail to rotate when car begins to travel, electric energy should be directly supplied to the induction coil(14) inside the cylinder(12) to generate torque, which is by the interaction between the energy supplied and the magnets attached, and then this electric energy can be shut off later.

To minimize leaked magnetic flux, diamagnetic substances such as engineering plastics or similar kind can be used for bearings and its plate connected to inside the cylinder(12) and each axe( 1,1-1).

The air resistance pressure passing through the cylinder(12), which is located in front part of the car. makes the blades attached to axe rotate, and accelerates rotary speed at above a certain level of velocity. This impulse reduces air resistance and increases axes( 1.1 -1 ) RPM(Revolutions Per Minute) simultaneously. Next, wind the coil( 14) on the inner side of the louver-type cylinder(12) and attach permanet magnet(13) at the end of the blades(2). This will make electrical rotation possible and maximize RPM.

When the axe(l, 1-1) RPM becomes 300-400(RPM) at above a certain level of velocity(40km/hr), gear box connected to each axe(l, 1-1) will double the RPM. and the power generator will convert the rotary force into electrical energy. 70% of this converted kinetic energy from the rotation will be used to charge the battery(6) by the control timer set in power generator, and the remaining 30% will be sent back to the coil(14) attached inside the louver-type cylinder. The latter interacts with the permanent magnet(13) attached at the end of the blade(2), maximizing axe rotation.

In general, motor RPM is determined by the number of poles. Motor with 4 poles runs at 1750 RPM. and with 6 poles at 1250 RPM as maximum. You can select maximum RPM by controlling the number of blades(2) attached on the axe (1) and its rotary radius in ihe louver-type cylinder.

The following example shows axe with four blades, so it is motor with 4 poles. The power generator can maximize its energy production when the above three processes work instantaneously. The battery car is enabled to produce more amount of energy than it requires for travelling, as well as recharging itself, through such multi-staged energy generating mechanism. The electric car can travel on without additional recharge, except the very first full-charged battery.

In short, by winding the coil(14) with permanent magnet(13-l) inside the cylinder and adding magnet(13) on the blade(2), the cylinder generates stronger energy, since the power generator produced electrical energy is being sent back to the coil.

In addition, each axe has 3 pairs of blades, (you can add more blades according to the length of the axe).

If the diameter of cylinder is /, blade radius of gyration Φ is set between 0.2/ and 0.5/ (0.2/<Φ<0.5/). Making number of axes rotate toward the same direction increases rotary force of axe. <Brief Description of Dra ings>

Currently producing electronic cars have limited travelling distance according to the battery capacity. Besides, they can not recharge themselves while travelling; they need extra time to recharge.

To solve these kind of problems, the invention is designed to self-recharge the battery, putting the louver-type cylinder with number of blades at the forepart of the frame. The air resistance pressure passing through the narrow louver-type cylinder will increase the speed due to the pressure differential. Moreover, magnet on the blade and the coil on the louver-type cylinder will plus the RPM.

Basically, it uses air resistance as source of energy. But it further increases energy as air resistance pressure passes through the louver-type cylinder. Finally, it gets additional kinetic energy through the coil inside the cylinder and blades with magnet. The faster the car travels, the more amount of energy on each process will be produced.

Above mechanisms applied, details of charging the battery for the electric car is explained according to the patent application format and sample figures will be followed.

Electric cars are classified in the way similar to the normal cars. Louver-type cylinder of 1000cc-1400cc as small size, 1500cc-1900cc as medium, and above 2000cc as large, friction considered. Radius of gyration of blade is set according to the size of the cylinder. Following example will present the medium sized car. which takes cylinder diameter of 400mm and blade radius of gyration of 350mm as standard.

The RPM marks very low level from the starting to 5km. due to the weight of the axes and blade(cumulated weight is 5-6kg). This is not enough to generate necessary amount of electrical energy.

Namely, weight of the three axes(l.l-l) set in the louver-type cylinder(12) and 3pairs of blades(2.2-l ) generates bigger friction loss; energy spent is larger than produced. But when the speed gets to 20km/hr, RPM becomes 260, and at 30km/hr, RPM gets beyond 300. Above 40km/hr. due to the centripetal force generated by weight of the blades themselves and impulse from accelerated air speed, RPM increases sharply, (between 20-30km. it shows linear increase of 20RPM for every 5km; it increases by 110% from 30km. 115%) from 40km. and 125% beyond 60km.) The main source of energy to run the blades(three pairs: total 32) attached to each axe set inside the louver-type cylinder is provided by slope of the blades, which generates air-flow pressure.

When the front section of the blade with slope of 35-40 degrees rotates, the rear section push backward the air inside the cylinder, generating impulse as inhaled air speed due to the pressure differential increased enormously. RPM at 80km increases in proportion to the squared rate of speed increase [ RPM at 80km ∞ (rate of speed increase)² ]

In this way, electrical energy can be self-supplied by using air resistance pressure as source of energy, and at the same time, additional rotary force is produced by sending this energy to the coil(14) with magnet(13-l) inside the cylinder, at which it interacts with the magnet(l 3) attached on the blade(2). To protect the system from overcharging, some extra appliance to intercept overcharging can be put.

As seen from the above example, rotary force from air resistance pressure was used (firstly), and secondly, accelerated rotary force from the inhaled air speed increased due to the pressure differential is used. To increase efficiency of rotary force, multiple set of axes are provided with gears.

What this invention looks for is self-recharging technique for electric car, using the above explained louver-type cylinder(12), pairs of blades(2,2-l) attached to the number of axes(l .l-l), coil(14) with magnet(13-l) inside the cylinder and magnets(13) on blades(2).
