The present invention refers to a battery group and to a system composed of a plurality of storage batteries for electrical means , to form a rotating mass, which determines a weight reduction of the batteries themselves .

Batteries capable of reducing their weight by rotating the batteries themselves are not known in the art .

Object of the present invention is providing a battery group and a system comprising such storage batteries of reduced weight compared to the static electric batteries of the known art , allowing better performance , greater autonomy for the same energy used .

Another advantage of the present invention is obtaining an improvement in the anti-rollover and anti-roll stability of an aquatic vehicle designed to use such storage battery devices .

The aforementioned and other purposes and advantages of the invention, which will emerge from the following description, are achieved with a battery group and a storage battery system as described in the respective independent claims . Preferred embodiments and non-trivial variant s of the present invention form the subject of the dependent claims .

It is understood that all attached claims form an integral part of the present description .

It will be immediately obvious that innumerable variations and modifications ( for example relating to shape , dimensions , arrangements and parts with equivalent functionality) can be made to what is described without departing from the scope of the invention as appears from the attached claims .

The present invention will be better described by some preferred embodiments, provided by way of non-limiting example , with reference to the attached drawings , in which :

- FIG . 1 shows a perspective view of an embodiment of the battery group according to the present invention ;

- FIG . 2 shows a perspective view of another embodiment of the battery group according to the present invention ;

- FIG . 3 shows a side view of a car equipped with the battery group according to the present invention ; and

- FIG . 4 shows a perspective view of a drone equipped with the battery group according to the present invention .

Referring to the figures , it can be noted that the battery unit 1 according to the present invention comprises at least one element 3 , preferably in the shape of a drum and at least one axis 5 operatively connected to the element 3 by at least one bearing 17 .

In particular, the axis 5 is designed to allow the rotation of the element 3 which can be in light metal such as aluminum, or in composite material .

Advantageously, the element 3 act s as a supporting structure on which a plurality of batteries 7 of any shape , cylindrical or square , are mounted in special niches arranged to compose a battery pack connected to each other through a plurality of conductive tracks 9 , which act from an electric collector, on which a plurality of brushe s 11 slide , suitable for collecting the electric energy given by the batteries 7 and transmitting it to use through at least one positive cable 13 and at least one negative cable 15.

Furthermore, the element 3 thus composed is mounted on the axis 5 rotating on bearings 17 and is driven, at high rotation speed, by at least one electric motor device 19 which is able, once the rotation of the element 3, to decrease its weight by about 80%.

In fact, due to the effect of the well-known principle of the gyroscope, for which a mass rotated at a high number of revolutions on an x, y plane, a force intervenes that pushes upwards and causes a considerable, proportional decrease in weight, at its angular velocity.

In particular, this battery group 1 is advantageous for an application on an aircraft or on an electric vehicle, in which the weight of the batteries is equal to half of the total weight when fully loaded, in which this ballast determines all the performances, decreasing speed and autonomy.

On the other hand, in an aircraft or motor vehicle equipped with such a battery group 1, being able to count on a system that produces a weight reduction of 80%, considerable advantages are obtained, translated into better performance, greater autonomy for the same energy used, easily explained by the fact that on an aircraft such as a drone , the weight of a battery pack which is about 80 kg; using the technology of the rotating mass battery pack 1 result s in a reduction of 65 kg less than the same static battery pack .

In particular, a latest generation electric vehicle , where the battery pack can weigh up to 300 kg, thanks to the use of the rotating storage battery system, due to the ef fect of the rotating mass, can cause a reduction of 240 kg les s , such as to to shoot up all the performances unmatched by any other invention aimed at increasing energy efficiency .

For the applications , some rules or parameters must be respected, for example the rotating mass battery packs must be cylindrical or disc shaped .

Furthermore , in the storage battery system installed on a vehicle , these storage battery devices 1 must always be of an even number and one must always be with opposite rotation to the other, since in addition to the upward force , which decreases the weight , a force is also created that causes the entire mass to rotate clockwise or by rotation of the opposite mass, counterclockwise . Advantageously, each rotating mass battery group 1 has an electric motor device 19 which determines its rotation ; the power of this motor device 19 is negligible and so small that it does not affect the energy balance .

In any case , should the rotation of the mass fail , the battery pack 1 regains its weight and the performance returns to those of a heavier vehicle .

Furthermore , this battery group 1 finds a double-effect use also on water vehicles and/or boats where gyroscopes are normally used to counteract rolling and pitching at sea, with the battery group system 1 the performance of electric boats is improved and at the same time the problem of stability is solved .

In the electric vehicle industry, the weight factor of the batteries determines and affects the entire project in terms of performance and autonomy for the same energy used, with the adoption of the rotating mass battery group 1 it will be possible to have aircraft and vehicles in which the the same autonomy is now obtained with a much lower quantity of batteries , or by maintaining the same weight of batteries , a much greater autonomy is obtained compared to the same vehicle without battery group 1 with rotating mass.
