Abstract
Official abstract text for this publication.
An apparatus ( 100 ) includes at least one electrochemical cell ( 106 ) and at least one pass element ( 104 ) serially coupled with the electrochemical cell. A control circuit ( 102 ) is operable to open the at least one pass element when a charger ( 105 ) or power supply ( 107 ) is connected to the electrochemical cell for at least a predetermined time and to measure an open circuit voltage of the at electrochemical cell to determine a state of charge. The control circuit can then close the pass element to charge the electrochemical cell, determine an amount of the charge, and store an estimated energy capacity of the electrochemical cell based upon the open circuit voltage and the amount.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of estimating cell capacity, comprising: opening a circuit coupled serially between one or more cells of a battery and a charging terminal in response to detecting a charger coupled to the charging terminal and prior to the charger charging the one or more cells; measuring, with a control circuit, an open circuit voltage of the one or more cells to determine a state of charge of the one or more cells; after the measuring, closing the circuit…
