BATTERY CHARGING DEVICE OF AN ELECTRIC VEHICLE DURING THE

MARCH

D E S C R I P C I O N

OBJECT OF THE INVENTION

The present invention relates to a battery charging device of an electric vehicle during travel, taking advantage of the air flow that affects it to recover energy.

BACKGROUND OF THE INVENTION

Electric propulsion vehicles are known which comprise a frame with wheels, an electric propeller and electric batteries or accumulators for feeding said electric propeller.

A problem that arises, and that significantly delays the implantation of these electric vehicles outside the cities, is the limited autonomy and the difficulty currently existing for them to find charging points during long trips, and to find them the time that Requires recharging the batteries.

The state of the prior art consists of recharging the batteries when their capacity is exhausted, which requires a very precise planning of electric car trips, not only in distance, but in speed, since the electric consumption is a function of is.

This inconvenience is partially solved with the battery charging device of an electric vehicle during the march, taking advantage of the air flow that affects the vehicle to recover energy.

The battery charging device of an electric vehicle during the course of the invention is applied to electric vehicles, which comprise a frame with wheels, an electric propeller and electric batteries or accumulators for feeding said electric propeller, and in accordance with the Invention said device in its most basic embodiment comprises:

-at least, a wind turbine interposed in the aerodynamic flow due to the movement of the vehicle,

-at least, an electric generator mechanically coupled to said turbine or turbines, and -at least, an electric charge regulator electrically intercalated between the generator and the batteries to supply electric power of the electric generator under conditions of charging said batteries.

In this way it is possible to incorporate in the vehicle some autonomous electricity production means consisting of the turbine or turbines, which associated to the electric generators that produce electric energy that charges the batteries that feed the propeller, increasing the autonomy of the electric vehicles when They are moving.

In addition it has been found as an additional advantage that, in electric cars, due to the absence of explosion engines that were in the front compartment of them, when this free space is left it is very easy to locate the turbines in said location, taking advantage of the openings of the car's own calender. Following the turbines, whether axial or centrifugal, the electric generators can be placed, interleaving if a reduction transmission is considered necessary. or multiplier.

In this document, the aerodynamic flow is understood as the flow of air that is generated around and / or by the open parts of the vehicle due to the difference in speeds between the vehicle and the air velocity, when the vehicle travels.

PREFERRED EMBODIMENT OF THE INVENTION

The battery charging device of an electric vehicle (1) during the course of the invention is applicable to vehicles comprising a frame (2) with wheels (3), an electric propeller (4) (in this example a propeller (4 ) on each front wheel) and electric batteries (5) for feeding said electric propeller (4), which according to the invention comprises:

-at least, a wind turbine (9, 10) interposed in the aerodynamic flow (6) due to the movement of the vehicle (1),

-at least, an electric generator (7) mechanically coupled to said turbine (9, 10) or turbines, and

-at least, an electric charge regulator (8) electrically intercalated between the generator (7) and the batteries (5) to supply electric power from the electric generator (7) under conditions of charging said batteries (5).

In this example there is a second regulator (80) that regulates the delivery of energy from the batteries (5) to the motors (5) depending on the use of the accelerator and brake pedals (50). In addition, a reduction or multiplier transmission (12) between the turbine or turbines (9, 10) and the generator (7) can be arranged to adapt the most optimal speeds of both elements.

Ideally, the turbines can be axial (9) with flow directed parallel to the axis, as seen in fig 1 and 2 or centrifugal (10) with flow directed perpendicularly to the axis, as seen in fig 3 and 4. embodiment of figures 1 and 2, in addition, the transmission (12) serves

to couple the five turbines (9) available to a single generator (7).

Very preferably the turbines (9, 10) are arranged in the front part (11) of the front compartment (13) of the vehicle (1), and eventually, if there are, for 5 lateral openings, taking advantage of the space traditionally reserved for the thermal motors of the vehicles, which are dispensed with in electric vehicles. In addition, in this way the turbines (9, 10) can be placed facing the calender (14) of the vehicle (1) and therefore frontally to the aerodynamic flow (6), achieving the highest efficiency. Additionally or in addition, conductive conduits (15) of the flow can be provided

10 (6) aerodynamic towards the turbines (9, 10), as seen in Figs. 3 and 4, where the

channeling (15) directs and concentrates the flow (6) towards the centrifuge turbine (10). The flow of air from the turbines can be used to cool other devices that require it and are in the engine compartment.

15 The possible arrangement of a lubrication circuit for the turbines (9, 10) and possibly for the transmission (12) has also been foreseen. Said circuit would comprise a lubricant pump (21) and some impulse (22) and return lines of the lubricant, the lubricant being able to take the lubricant from a tank or carter (24) through a filter (25).

20 Describing sufficiently the nature of the invention, it is indicated that the description thereof and of its preferred embodiment should be interpreted in a non-limiting manner, and that it encompasses all possible embodiments that are deduced from the content of the present memory and claims.
