Filed:

Jul 25, 2012

Appl. No.:

13/557676

Inventors:

Richard Scott BOURGEOIS - Albany NY, US
Vincent Boccanfuso - Clifton Park NY, US

International Classification:

H02J 7/00

US Classification:

320156

Abstract:

A method for a rechargeable battery is disclosed that includes applying a charge voltage to the rechargeable battery; monitoring a battery voltage and a battery current of the rechargeable battery; and identifying a top of charge condition when for a defined time period the battery voltage is within a voltage tolerance of the charge voltage and the battery current is within a current tolerance of a threshold current. Also disclosed is a rechargeable battery system.

Abstract:

A system and method of use including a controller responsive to a deviation in absolute value or relative slope and operable to terminate a discharge operation in an energy storage device is provided. The absolute value or relative slope is determined at sampling frequency based upon a combination of measured operating parameters, for example, potential and current. Any deviation in the absolute value or relative slope indicates that a threshold limit in the available energy of the system has been reached, for example when active materials in the device are at a point of depletion, indicating a need to cease the discharge operation. The system and method operate on a real-time basis, providing instantaneous SOH information with regard to the device.
