Definitions

  • the present invention relates generally to power supplies for electric or hybrid automobiles and, more particularly, to a flywheel/battery for electric or hybrid automobiles.
  • a battery of an electric or hybrid vehicle operates as a flywheel which is rotatably mounted to the automobile to thereby form a flywheel/battery.
  • the flywheel/battery is in mechanical communication with the transmission and drive shaft of the automobile, and is preferably formed in the shape of a rotatable cylinder.
  • the flywheel/battery is stored in the trunk of the automobile. In another embodiment, the flywheel/battery is stored in an engine compartment of the automobile.
  • the drive shaft of the vehicle When the automobile is determined to be decelerating or is about to decelerate (i.e., when a brake is engaged and/or when the driver's foot is removed from an accelerator pedal ⁇ , the drive shaft of the vehicle, through the transmission of the vehicle, engages and causes the flywheel/battery to spin.
  • the flywheel/battery rotates above a threshold rotational speed relative to a speed of the automobile
  • the drive shaft is disengaged from the flywheel/battery so that the flywheel/battery freely rotates.
  • the continued rotational motion or inertia of the flywheel/battery is used when acceleration of the automobile is detected, such as when a brake is disengaged or an accelerator is engaged. If the flywheel/battery is rotating at this time, the rotation is applied to the drive shaft to aid the acceleration of the automobile.
  • the flywheel/battery thus provides a way to utilize the otherwise unused mechanical energy (i.e., rotating mass) of the flywheel/battery of an automobile in an advantageously, mechanically-useful way by transferring rotational energy from the drive shaft to the flywheel/battery for a short time (e.g., while standing still at a stop light, etc.), and by transferring the rotational energy from the flywheel/battery back to the drive shaft during acceleration to assist in commencing motion of the automobile.
  • a short time e.g., while standing still at a stop light, etc.
  • the Figure is an illustrative schematic diagram of a flywheel/battery in mechanical communication with a transmission and drive shaft of an automobile in accordance with an exemplary embodiment of the invention.
  • flywheel/battery 10 shown in mechanical communication with a transmission 12 and drive shaft 14 of an automobile (not shown) .
  • the flywheel/battery 10 is sized to meet the electrical requirements of the particular automobile in which the flywheel/battery 10 is disposed. Therefore, the size of the flywheel/battery 10 will vary depending on the automobile in which it is implemented or disposed.
  • the flywheel/battery 10 is formed in the shape of a rotatable cylinder having an axis and the flywheel/battery 10 is stored in the trunk of the automobile.
  • the flywheel/battery 10 is configured as a rotatable cylinder and is stored in an engine compartment of the automobile.
  • the flywheel/battery 10 is mounted in the automobile and oriented with its axis in parallel to the longitudinal axis of the automobile.
  • the rotation of the flywheel battery 10 is in a direction transverse to the length of the automobile. As a result, the rotation of the flywheel/battery is unaffected by the forward or rearward motion of the automobile .
  • positive and negative electrical contacts 16 and 18 extend outward from the ends of the cylindrical flywheel battery 10 along its axis, and are connected to the alternator of the automobile (not shown) in a manner that is known to those skilled in the art. Insulating (non-conductive ⁇ tubes 20a and 20b are disposed over and shield the electrical contacts 16 and 18. It will be known to those of ordinary skill in the art that both electrical contacts 16 and 18 can, likewise, be positioned on the same side of the battery.
  • First ends 22a, 22b of the non-conductive tubes 20a and 20b are respectively coupled to the outer body of the flywheel/battery 10.
  • the non-conductive tubes 20a and 20b are also provided with second ends 24a, 24b.
  • Located at the second ends 24a, 24b are one or more first gears 26a, 26b configured to rotatably engage one or more second gears 28 and 30, respectively.
  • the second gear 30 couples the flywheel/battery to a shaft 34 that, in turn, is coupled to the transmission 12 of the automobile.
  • the transmission 12 of the automobile is coupled to the drive shaft 14, which is coupled to a wheel axle 36 by a coupling device, such as a rear differential.
  • gear 28 is a freely rotating gear.
  • gear 28 is used to engage a regenerative braking system (not shown) .
  • the gear arrangements can comprise wheel and tooth arrangements.
  • the gear arrangements comprise worm gears or other known gear arrangements, and it is not the intention of the disclosed embodiments to be limited to any one particular gear mechanism.
  • the drive shaft 14 In operation, when the automobile is determined to be decelerating or is about to decelerate (i.e., when a brake is engaged and/or when the driver's foot is removed from the accelerator pedal of the automobile, etc.), the drive shaft 14, through the transmission 12, engages and drives the second gear 30, which engages and drives gear 26b, which causes the flywheel/battery 10 to rotate. In this manner the mass of the flywheel/battery 10 is coupled to the drive shaft 14 to assist in slowing down the driveshaft.
  • Means for engaging and disengaging the first and second gears may be achieved, for example, by way of a transfer case or clutch device 32 controlled by the transmission 12.
  • the power transmittal is achieved with a set of gears.
  • this feature is controlled by the driver, where the driver can place the transfer case into either "two wheel drive” or "four wheel drive” mode. This is sometimes accomplished by a shifter, similar to that in a manual transmission.
  • the switching of the transfer case 32 is electronically operated by an internal switch (not shown) based on a determination of the motion of the automobile, e.g., the automobile is at a stop, is accelerating or decelerating, etc.
  • the engagement and disengagement of the gear 30 is achieved in the same manner in which automatic or manual transmissions engage and disengage their gears. Consequently, the complex mechanical structure associated therewith is not shown for purposes of clarity.
  • the rotational energy that is used to start the rotation of the flywheel/battery 10 is thus subtracted from the rotational energy that is currently being used to provide the forward momentum of the automobile (via the rotational movement of the drive shaft 14 and wheels 38a and 38b) . That is, the drag on the drive shaft 14 due to the mass of the battery detracts from the rotational energy being used to move the vehicle forward. Consequently, an increase in deceleration is created.
  • the rotational energy from the drive shaft 14 is, instead, transferred to the flywheel/battery 10 and, thus, becomes subjected to the parasitic effect caused by the mass of the flywheel/battery.
  • This mechanical action serves to force the rotating drive shaft 14 to rotate the flywheel/battery 10, so that the rate at which the wheels and/or drive shaft 14 lose energy is increased due to the parasitic energy effect cause by the mass of the flywheel/ battery 10 on the drive shaft 14 of the automobile.
  • the mechanical action reduces the energy required for braking and, thus, advantageously reduces wear on the brake components of the automobile, such as the brake discs, rotors and/or brake pads .
  • the gears 30 and 26b disengage from each other and the flywheel/battery 10 will freely rotate.
  • the mass associated with the rotational motion or inertia of the flywheel/battery 10 is used to aid the acceleration of the automobile.
  • the gears 30 and 26b re-engage each other.
  • the rotational motion of the flywheel/battery 10 which is now coupled to the drive shaft 14 assists in the rotation of the drive shaft 14 via the transmission 12.
  • the rotational energy or mass of the flywheel/battery 10 is added to the rotational energy provided by the engine to help turn/rotate the drive shaft 14.
  • the produced mechanical motion helps reduce the mechanical strain or load on the engine or electric motor of the automobile -- which is least efficient in this range -- when accelerating the automobile from a full stop by utilizing the mass of the battery.
  • the mass of the flywheel/battery 10 increases the energy required to move the automobile from a standstill.
  • this effect is negated by the additive nature of the flywheel/battery to the rotation of the drive shaft, i.e., the overall energy consumption is a net positive gain.
  • the battery is required for automobile operation in any event, only now, in accordance with an embodiment of the invention, the battery is also used mechanically as a flywheel .
  • the above-described flywheel/battery 10 provides a way to utilize the otherwise unused mechanical energy ⁇ i.e., mass) of the battery of an automobile in an advantageously mechanically useful way by draining rotational energy from the drive shaft 14 during braking, storing the rotational energy for a short time (e.g., while standing still at a stop light, etc.), and using the stored rotational energy by transferring energy back to the drive shaft 14 during acceleration to assist in commencing motion of the automobi1e .
  • the flywheel/battery 10 is disposed in a housing 40 (indicated in the Figure by dashed lines) which does not rotate with the flywheel/battery and which is surrounded by a mineral or other non-conductive lubricating oil 42. In another embodiment, the flywheel/battery 10 is disposed in the housing 40 and surrounded only by air.
  • the disclosed embodiments of the flywheel/battery 10 advantageously provide a way to improve the operational efficiency of automobiles that are stopped and restarted often, such as buses or garbage trucks. Moreover, the disclosed embodiments of the flywheel/battery advantageously increase the operational range of an automobile because, at points of deceleration, energy is absorbed by the disclosed flywheel/battery .

Abstract

La présente invention se rapporte à une batterie/volant comportant une masse et montée rotative autour d’un axe dans une automobile électrique ou hybride pour augmenter l’efficacité de la batterie dans une telle automobile. Un premier engrenage est relié pour rotation à la batterie autour de l’axe, et un second engrenage est relié à un arbre d’entraînement de l’automobile. Le premier engrenage vient fonctionnellement en prise avec le second engrenage de manière séparable de sorte que, au cours de la mise en prise fonctionnelle, la batterie tourne lorsque l’arbre d’entraînement de l’automobile tourne. Un mécanisme est utilisé pour provoquer la mise en prise et la séparation des premier et second engrenages de sorte que, au cours de la mise en prise, (1) la rotation de l’arbre d’entraînement provoque la rotation de la batterie au cours du déplacement du véhicule et (2) la rotation de la batterie facilite la rotation de l’arbre d’entraînement au cours de l’accélération du véhicule, et de sorte que la masse de batterie facilite le ralentissement du véhicule.
