OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se puede incluir dentro del campo técnico de la automoción, en concreto, dentro del campo de los automóviles propulsados por motores eléctricos, los denominados automóviles eléctricos. The present invention can be included within the automotive technical field, in particular, within the field of cars powered by electric motors, so-called electric cars.
En particular, el objeto de la invención se refiere a un dispositivo de recarga de las baterías de propulsión de uno de tales automóviles eléctricos. In particular, the object of the invention relates to a device for recharging the propulsion batteries of one of such electric cars.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Las necesidades de reducir el consumo de combustibles fósiles han llevado al desarrollo de vehículos automóviles que incorporan baterías de propulsión adecuadas para alimentar un motor eléctrico responsable de obtener al menos parte de la potencia motriz necesaria para impulsar el vehículo. Una variante de dichos vehículos eléctricos son los denominados vehículos híbridos, que comprenden un motor eléctrico y un motor de combustión interna convencional. En dichos vehículos, el motor eléctrico suministra en exclusiva la potencia necesaria para la propulsión de automóvil eléctrico mientras dicha potencia (o equivalentemente, la velocidad alcanzada por el vehículo) es inferior a un determinado valor predeterminado, de modo que, para potencias o velocidades superiores a dicho valor predeterminado, se hace necesaria la colaboración del motor de combustión interna. The needs to reduce the consumption of fossil fuels have led to the development of motor vehicles that incorporate adequate propulsion batteries to power an electric motor responsible for obtaining at least part of the driving power necessary to drive the vehicle. A variant of said electric vehicles are the so-called hybrid vehicles, which comprise an electric motor and a conventional internal combustion engine. In said vehicles, the electric motor exclusively supplies the power necessary for the electric car propulsion while said power (or equivalently, the speed reached by the vehicle) is less than a certain predetermined value, so that, for higher powers or speeds at said predetermined value, the collaboration of the internal combustion engine is necessary.
A pesar del gran avance en el desarrollo de dichos motores, en la actualidad la autonomía de dichos vehículos manteniendo unas prestaciones razonables está limitada al orden de unos doscientos kilómetros. Habida cuenta de que el número de puntos de recarga habilitados es reducido, aparece el inconveniente del peligro de agotar las baterías de propulsión antes de encontrar un punto de recarga. Despite the great progress in the development of these engines, currently the autonomy of these vehicles while maintaining performance Reasonable is limited to the order of about two hundred kilometers. Given that the number of recharging points enabled is reduced, the drawback of the danger of exhausting the propulsion batteries before finding a recharging point appears.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención resuelve el inconveniente mencionado, por medio de un dispositivo de recarga de las baterías de propulsión destinadas a la propulsión de un automóvil eléctrico, según se explicará seguidamente. The present invention solves the aforementioned drawback, by means of a recharging device for the propulsion batteries intended for the propulsion of an electric car, as will be explained below.
El dispositivo comprende un depósito adaptado para recibir y contener aire a presión. El aire a presión puede provenir por ejemplo, de una de las tomas comúnmente presentes en estaciones de servicio. The device comprises a tank adapted to receive and contain pressurized air. Pressurized air can come, for example, from one of the sockets commonly present in service stations.
Adicionalmente, el dispositivo comprende una turbina conectada con el depósito y alimentada con aire a presión procedente de dicho depósito para obtener energía cinética en el eje de la turbina a partir de la energía de presión del aire del depósito. El dispositivo comprende adicionalmente un generador conectado al eje de la turbina para transformar la energía de giro del eje en energía eléctrica, así como el generador es eléctricamente conectable con las baterías de propulsión, para recargar dichas baterías de propulsión con energía eléctrica. El dispositivo de la invención permite aumentar la autonomía del automóvil eléctrico en casos en los que, por ejemplo, no se dispone de una toma eléctrica de recarga para recargar las baterías de propulsión, pero sí existe disponibilidad de aire a presión, tal como en una estación de servicio en carretera. De acuerdo con una realización preferente de la invención, el dispositivo está integrado en el propio automóvil, si bien no existe inconveniente en considerar la instalación de dicho dispositivo en un lugar fijo, dejando libre una conexión eléctrica para comunicar el generador y las baterías de propulsión. Additionally, the device comprises a turbine connected to the tank and fed with pressurized air from said tank to obtain kinetic energy in the turbine shaft from the pressure air of the tank. The device additionally comprises a generator connected to the turbine shaft to transform the rotation energy of the shaft into electrical energy, just as the generator is electrically connectable with the propulsion batteries, to recharge said propulsion batteries with electrical energy. The device of the invention makes it possible to increase the autonomy of the electric car in cases where, for example, an electric recharge socket is not available to recharge the propulsion batteries, but there is availability of pressurized air, such as in a road service station. According to a preferred embodiment of the invention, the device is integrated in the car itself, although there is no inconvenience in considering the installation of said device in a fixed place, leaving a free electrical connection to communicate the generator and the propulsion batteries.
De manera preferente, el dispositivo de la invención puede incorporar adicionalmente su propia fuente de aire a presión, preferentemente un compresor, que proporciona aire a presión al depósito. La fuente de aire a presión puede ser, para su alimentación, eléctricamente conectable a las baterías de propulsión, si bien se prefiere que la fuente de aire a presión esté alimentada con una fuente de energía independiente de las baterías de propulsión, como por ejemplo, acumuladores empleados para la iluminación o el arranque del vehículo, dispositivos fotovoltaicos, etc. Preferably, the device of the invention can additionally incorporate its own source of pressurized air, preferably a compressor, which provides pressurized air to the reservoir. The source of pressurized air can be, for its supply, electrically connectable to the propulsion batteries, although it is preferred that the source of pressurized air be fed with a source of energy independent of the propulsion batteries, such as, for example, accumulators used for lighting or starting the vehicle, photovoltaic devices, etc.
El empleo de un compresor como particular fuente de aire a presión permite efectuar una pequeña recarga de las baterías de propulsión, solo con disponer de aire, aunque no sea aire a presión, para efectuar una pequeña recarga de emergencia en las baterías de propulsión, o incluso de emplear energía eléctrica de manera indirecta para recargar las baterías de propulsión, en el caso de que el dispositivo sea externo al vehículo y se disponga de una toma eléctrica para alimentar el compresor que no sea apta para recargar directamente las baterías. De manera preferente, la invención incorpora un conducto para reconducir el aire de salida de la turbina hacia el compresor para aprovechar la energía de presión remanente en el aire que abandona la turbina y disminuir el consumo del compresor. The use of a compressor as a particular source of pressurized air allows a small recharge of the propulsion batteries, only with the availability of air, even if it is not pressurized air, to carry out a small emergency recharge on the propulsion batteries, or even using electric power indirectly to recharge the propulsion batteries, in the event that the device is external to the vehicle and an electrical outlet is available to power the compressor that is not suitable for directly recharging the batteries. Preferably, the invention incorporates a conduit to redirect the turbine outlet air to the compressor to take advantage of the remaining pressure energy in the air leaving the turbine and decrease the consumption of the compressor.
Para evitar embalamientos en la conexión turbina-generador, así como, en el motor del compresor, caso de que esté accionado por el motor eléctrico del vehículo, se pueden disponer de cajas de cambio dispuestas entre el motor eléctrico del vehículo y el compresor, así como entre el eje de la turbina y el generador. Dichas cajas de cambio limitan la velocidad máxima a la que pueden girar la turbina y el compresor. DESCRIPCIÓN DE LOS DIBUJOS To avoid packaging in the turbine-generator connection, as well as, in the compressor engine, if it is driven by the electric motor of the vehicle, gearboxes arranged between the electric motor of the vehicle and the compressor can be arranged, as well as between the turbine shaft and the generator. These gearboxes limit the maximum speed at which the turbine and the compressor can turn. DESCRIPTION OF THE DRAWINGS
