1. Field of the Invention The present invention relates in general to the field of electrical energy storage and delivery devices. In particular, the present invention relates to an instant charge battery and method of charging and discharging same.

2. Prior Art The two most common electrical energy storage and delivery devices are batteries and capacitors. Batteries prove to be more practical of the two in the majority of applications of portable electric devices due to the fact that they are able to deliver a relatively constant voltage over an extended period of time. With the increase in popularity and dependency on portable electric devices, chargeable batteries are not only practical, but economical as well. The charging time of chargeable batteries varies greatly - anywhere from approximately an hour to several hours, depending upon the size and type of chargeable battery. This charging time contrasts starkly to the charging time for capacitors - which can charge in a matter of seconds. Although capacitors have the advantage of charging quickly, they have the disadvantage of being unable to deliver a constant voltage over a sustained period of time. To achieve the desirable qualities of both, batteries and capacitors can be combined for specific applications. Battery/capacitor combinations are well known in the art. The most common application of this combination is in the photo flash, hi this battery/capacitor combination, a battery is used to charge a capacitor for the purpose of providing a high intensity burst of electricity to flash the strobe of the camera. Another application of the battery/capacitor combination is in portable radio transmitter/receivers, hi this combination, the battery provides a constant level of power during the receiving/standby mode, hi the transmission mode, however, the radio requires a burst of power to transmit the signal. The capacitor provides that burst of supplemental power during radio transmission, hi both of these applications, the battery is used to charge the capacitor which, in turn, is used to provide energy for the use of an electrical device.

However, there is no prior art of battery/capacitor combinations where the capacitor provides a charging current to the battery. There certainly exists the need for battery/capacitor hybrids combining the quick charge qualities of capacitors with the constant level and extended delivery of electrical energy qualities that batteries posses. SUMMARY OF THE INVENTION

The present invention solves the drawbacks of long charging times for chargeable batteries by utilizing a capacitor or series of capacitors to quickly capture electrical energy - which, in turn, is transferred to a chargeable battery. The capacitor(s) should be of the type to discharge the stored energy over the longest period of time possible - not instantaneously. The prolonged transfer of energy from the capacitor to the battery enables the battery to charge more efficiently. The transfer of the electrical energy from the capacitor(s) to the battery is regulated by the charge circuit. The charge circuit optimizes the amount as well as the rate of transfer of electrical energy from the capacitor(s) to the battery.

The Instant Charge Battery will prove to be useful in a wide range of applications. It will be especially effective in low power consumption portable electronic devices such as, but not limited to, cell phones, PDA's, MP3 players, digital cameras and notebook computers.

In one embodiment of the invention, a single capacitor is utilized for the capacitor portion of the instant Charge Battery apparatus,

In another embodiment of the invention, multiple capacitors comprise the capacitor portion. The size and number of capacitors required for the capacitor portion is determined by the amount of electrical energy required to charge the battery portion. In another embodiment of the invention, the capacitor portion only provides a partial charge to the chargeable battery portion. This embodiment would be an important feature of an electronic device for use in emergency situations.

Ln yet another embodiment of the invention, the capacitor and charge circuit portions are integrated into the electrical device, such that the battery portion is separate and replaceable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a block diagram illustrating the schematic structure of the instant charge battery apparatus according to one embodiment of this invention. The DC power source provides the electrical energy necessary to charge the capacitor portion 1 of the Instant Charge Battery apparatus. It can be in the form of an AC transformer such as to convert household AC electricity into the appropriate DC voltage and current for the charging of the capacitor portion 1. The DC power source can also be in the form of a DC adaptor (such as a car adaptor) so as to convert a DC voltage and current (such as from an automobile power outlet) into the appropriate DC voltage and current for the charging of the capacitor portion 1. The AC/DC converter and/or DC adaptor may be either internal or external to the electrical device utilizing the Instant Charge Battery apparatus.

Capacitor portion 1 comprises singular or multiple capacitors for instantly capturing electrical energy from the DC power source. This captured electrical energy is then transferred to the chargeable battery portion 3 via the charge circuit portion 2. The charge circuit portion 2 regulates the charging of the chargeable battery portion 3 from the capacitor portion 1.

The multiple capacitor configuration of the capacitor portion 1 would allow for a more effective charging of the chargeable battery portion 3 by sustaining the charging current to the chargeable battery 3 over a longer period of time. This prolonged charging time is accomplished as each capacitor transfers its electrical energy in series or parallel. Conceivably, sequential transfer would be the most effective. The chargeable battery portion 3 can be of any chargeable / rechargeable battery cell(s) such as, but not limited to, NiCad, NiMH or Lithium-ion. The chargeable battery portion 3 may consist of either singular or multiple chargeable battery cells.

The electrical device can be any instrument or equipment that requires electrical energy in order to operate. The present invention would be exceptionally useful for portable electronic devices such as cell phones, PDA's, notebook/laptop computers, MP3 players, digital cameras, radios, etc. - especially with the advent of low power consumption technology for these types of devices.
