It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA hybrid energy storage system (10) including a first energy storage device (12), such as a secondary or rechargeable battery, and a second energy storage device (14), such as an electrochemical capacitor. The electrochemical capacitor provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices. The first and second energy storage devices are coupled to a current controller to assure that pulse transients are not applied to the battery cell as a result of charging the capacitor. | InventorsAssigneeApplicationNo. 755620 filed on 11/25/1996US Classes:429/3, HAVING PULSE FEATURE429/7WITH NONBATTERY ELECTRICAL COMPONENT ELECTRICALLY CONNECTED WITHIN CELL CASING OTHER THAN TESTING OR INDICATING COMPONENTSField of Search429/3, HAVING PULSE FEATURE429/7WITH NONBATTERY ELECTRICAL COMPONENT ELECTRICALLY CONNECTED WITHIN CELL CASING OTHER THAN TESTING OR INDICATING COMPONENTSExaminersPrimary: Kalafut, StephenAttorney, Agent or FirmUS Patent References4296461, Battery package with DC to DC converterIssued on: 10/20/1981 Inventor: Mallory , et al.4992340, Intrinsic safe battery having self test capability Issued on: 02/12/1991 Inventor: Tidwell, et al.5587250Hybrid energy storage system Issued on: 12/24/1996 Inventor: Thomas, et al.
