International Classification:

H01M 1046

US Classification:

320132

Abstract:

Method and apparatus for calibrating a rechargeable battery for mobile telephones and other electronic devices. Calibration is accomplished during a process of completely charging the battery by determining the total amount of charge accepted by the battery during the charging process, and providing a value of total charge capacity of the battery based, at least in part, on the total amount of charge accepted by the battery. The total charge capacity of the battery is used to calculate remaining battery capacity and to predict the remaining operational time of the device. Alternative calibration procedures are provided if the battery is not completely discharged before charging or if the battery is not fully charged by the charging process. The calibration procedures of the invention require no interaction from a user (other than his initiating the normal charging process), and typically permits a calibration to be carried out notwithstanding varying usage habits of different users.

International Classification:

G06F 1/00

US Classification:

713340, 713324

Abstract:

A first battery assembly is in a first battery housing that is mechanically engageable with a portable computer, and a second battery assembly is in a second battery housing that is mechanically couplable to the first battery housing.

International Classification:

H02J 7/00

US Classification:

320134, 320136

Abstract:

The provision of a mode in silver zinc batteries where a user can access extra capacity as an emergency reserve for times when extra capacity is needed. While this temporarily increases capacity, it does not detrimentally affect cycle life over the longer term, and it permits a silver zinc battery to essentially mimic the long term capacity and cycle life characteristics of a lithium ion battery while still affording inherent advantages associated with silver zinc batteries. In a variant embodiment, this ability to temporarily increase capacity is optimally employed at the end of a battery life cycle in a controlled “roll-off” that accords additional cycles of battery service life. In another variant embodiment, the general capability to control capacity is employed to gradually decrease the available capacity of a battery over the life of the battery, to thereby extend the battery service life.

H01M 6/00

US Classification:

429149, 296231

Abstract:

The invention described herein includes a method and apparatus comprising a plurality of battery cells electrically coupled to produce at least one voltage at a terminal, wherein the plurality of battery cells includes a plurality of junction areas. Each junction area comprises two battery cells longitudinally arranged such that an end of one battery cell faces an end of another battery cell. In a majority of the junction areas, the venting end of one battery cell does not face the non-venting end of the other battery cell.
