Description

DESCRIPTION

Eco-friendly battery charger for 100% electric vehicles.

Technical sector

The scope of our invention is in any land, sea, air and / or space vehicle, regardless of the motor system it has, that is, it can be coupled in traditional vehicles, with engines of: explosion (2 and 4 times ), gas, hydrogen battery or radioactive material and in 100% electric vehicles, the latter type of vehicles being the ones that can use it the most, since it is a system that takes advantage of forces outside the vehicle, to help generate energy.

Background of the invention

Formerly for the systems of charge of batteries the dynamos were used.

Currently the alternators are responsible for this charge, the former having been deprecated. Both (dynamo and alternator) are moved from the moving parts of the engine, through belts of different profiles. But these charging systems are those used in current vehicles with explosion engines (whose fuel is gas-oil or gasoline), gas engines (whose fuel is gas or LPG) or hydrogen engines (whose fuel is hydrogen stack). In all cases, when the current generating system (alternator) starts working, there is an electromotive force that opposes the cause that generates it (Lenz's Law). That is why, when the alternators start working, they consume several horsepower of the engine to which they are connected. In engines of a certain power, which are subtracted from some horsepower for this reason, they are not noticed by the driver in question. And in this way we are producing the current to charge the battery and for the own consumption of the different electrical and electronic circuits of the vehicle.

The problem comes in 100% electric vehicles. As the heart and at the same time, the fuel, in these vehicles, are the batteries themselves, if we connect an alternator, which consumes vast horsepower when it is working, we are quickly discharging the batteries. This is because the alternators cannot produce more energy, than that of the source to which they are connected, which in this case are the electric vehicle's batteries. If that were possible we could be talking about the perpetual motive, and this, according to all the principles of physics, is not possible. You cannot produce more than what is consumed.

That is why, so charging batteries in electric vehicles, is a big problem. At the moment they are destined to make fast loads, in those stations and / or points that exist, within the geography where they circulate and during the long stop time, to make them a load less rapid and more prolonged in time. Both one and the other, are charges derived from the connection to the existing power grid. This limits the use and the kilometers to travel.

Explanation of the invention.

The present invention consists in placing one or several turbines in the front or front of electric vehicles (bicycles, mopeds, motorcycles and cars, etc.), taking advantage of the air that hits us in this part of it, when it is subjected to a displacement, that is, when it is circulating. Like, the one that the air gives you, directly in the frontal part, during the displacement, is inevitable, we take advantage of this continuous blow of air, to move the blades of the propeller, of a small rotor, which will produce a small electrical energy, which is also 100% ecological.

In our invention the assemblies of the propellers will be made directly on the axis of rotation of the alternator (figures 1,2 and 3) or with interposition of a multiplier and / or speed reducer and / or torque, between the propeller and the alternator ( figures 1st, 2nd and 3rd).

The amount of small turbines to be placed, as well as the diameter of the propeller will be based on the aesthetics of the vehicle where they will be coupled and the amount of energy we want to take out. The larger the propeller diameter (D) (figure 4) and the greater the air blow (F) (figures 7 and 8), the more torque or force is generated on the rotor shaft (figures 7a and 8) and therefore, greater force Electromotive we can beat.

Our invention consists of three types of propellers to be placed in two different types of mounting:

The first assembly of our invention, is to place one or several turbines with the propellers located on the front (figure 7) and just behind place the rotor or alternator to move, or, place the propeller followed by a multiplier and / or reducer and subsequently the alternator (figure 1a). This type of turbines would be mounted inside circular ducts (figure 7) and whose inner diameter (D1) (figure 7) will vary depending on the energy we intend to take and the aesthetics of the vehicle where they will be coupled. The force (F) (figure 7a) with which the air hits the propeller, multiplied by the radius (r) of this figure (7a), gives us a torque or motorcycle torque (M) on the shaft, capable of overcoming the resistance that opposes us the alternator that we intend to spin (taking into account Lenz's Law), to produce some electrical energy with which to charge the battery.

Using the units of the international system, the force (F) is expressed in Newton (N), the radius (r) is expressed in meters (m) and the torque obtained (M) is expressed in Newton per meter (N-m).

M = F r; (N-m)

The design of the alternator also intervenes in the amount of energy obtained, such as: type of winding, number of poles, diameter of the copper wire used, speed of rotation, type of material of the magnets, among others.

In our case we would have to develop a small alternator, according to the forces with which the air hits the propeller of our turbine, while the vehicle is circulating.

As an example, they can be placed on the lower front of a car, simulating fog lights (figure 13) or in the lower part of a motorcycle, moped and / or electric bicycle, where it would be aesthetically well seen (figure 14).

The second type of assembly of our invention is to place one or more turbines with elongated blades. These blades can be parallel to the axis of rotation (figure 5) or can have a helical shape to the axis of rotation (figure 6). The diameter (D2) (figures 5 and 6) of this type of turbines will be a function of the power we want to draw, as in the previous case, the larger the diameter of the propeller, the greater the torque we will obtain in the axis of rotation and therefore greater strength we can overcome. The force (F) (figure 8) that the air exerts on the blades of this turbine, multiplied by the radius (r) (figure 8) of the propeller that forms the same, gives us a torque or torque (M ) expressed in Newton per meter (Nm).

In these last two types of elongated blade turbines, the alternator will be assembled at any end of the turbine (figures 9 and 9a) and (figures 10 and 10a). Same as him In the previous case, the energy we want to take out, not only depends on the design of the turbine and its blades, but also depends on the design of the alternator that we are going to couple.

As an example, this type of turbines could be placed in the central front part of the vehicle (figure 13), just behind the front grille, grill or grille, where the air currently enters to cool the water and air conditioning radiators . The amount of turbines to be placed will depend on the energy that we want to get to each of them and the space that the vehicle designer leaves.

We will play with the combination of the assembly of some and other turbines, to reach the battery charge values that are needed, depending on the power installed in the vehicle we are treating.

Preferred Embodiment of the Invention

One way to apply our invention is to carry out a front propeller turbine assembly and then an alternator (figure 1) or a turbine, multiplier and / or reducer assembly and the alternator (figure 1a). All this set is mounted inside a circular duct. The purpose of this assembly is to channel the air and make it hit the propeller to make it rotate. In this turn we also rotate the alternator and consequently, this provides us with a small amount of electrical energy, which previously rectified, is suitable for charging the battery.

The type of elongated blade turbine (parallel and / or helical to the axis of rotation) (figures 5 and 6), will be mounted on supports, behind the calender, grille or front grille of the vehicle (figure 8a) and the continuous blow of the air, while the vehicle is moving, makes the blades move and therefore we will move the alternator, providing a small amount of electric energy, which previously rectified, is suitable for charging the battery. Like the previous case, the turbine can be mounted directly on the alternator shaft (figures 2 and 3) or with a multiplier and / or reducer, sandwiched between them (figures 2a and 3a).

The objective of the assembly of both types of turbines, with their respective small alternators, is to charge the battery of the electric vehicle, while it is in motion. This charge gives us greater autonomy, being able to dispense with the current fast charges, which only 10 do is reduce the life of the batteries. In addition to this type of load is 100% ecological to take advantage of an external force, while we move.

The application of the invention in the different electric vehicles is to carry out the assemblies of the different types of turbines described, in the front part of said vehicles. This is to take advantage of the air blow that the vehicle receives during its movement. The type of front turbine (figure 7) can perfectly simulate fog lights, placed in the lower front of the car (figure 13) or in the lower central part of a motorcycle, moped and / or bicycle (figure 14). Its dimensions will depend on how, the aesthetics of the front of the vehicle remain, once these turbines have been integrated and the amount of electrical energy we want to take out. The greater the diameter of the propeller (D) (figure 4), the greater the torque we obtain and therefore the greater the force we can overcome, that is, the greater the alternator we can move and therefore, the more energy we can obtain.

The dimensions of elongated blade turbines, as in the previous case, are exposed to the same reasons. The assembly of these can be horizontal (figures 11 and 12), vertical (figures 11a and 12 a) or with a certain inclination (a) with respect to the ground (figures 11b and 12b) and behind the calender, grill or front trellis carried by vehicles in the front (figures 13 and 14). The fins of the calender will be used to channel the air and force it to hit the blade, so that it rotates and in turn will rotate the alternator that is coupled, producing this electric power (Figure 8a).
