20090094465 | BATTERY PACK FOR PORTABLE COMPUTER - 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. A switch has a first configuration in which communication is established between the portable computer and the first battery assembly and a second configuration in which communication is established between the portable computer and the second battery assembly. | 04-09-2009 |
20090208823 | ESTABLISHING SPACE BETWEEN END OF CENTER GAS PIPE IN BATTERY AND BOTTOM OF BATTERY CAN - The gap between the bottom of a center gas vent pipe in a battery cell and the bottom of the cell can is established to be at least a minimum distance to reduce the risk of battery damage from inadequate gas venting. | 08-20-2009 |
20090233165 | Mitigating Rupture and Thermal Cascading of Battery Cells by Judicious Arrangement of Cells Inside a Pack - 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. | 09-17-2009 |
20120153902 | Controlled Regeneration of Solid Electrolyte Interface for Prolonged Cycling of Lithium Batteries - A system implements a first charging method or a second charging method during one or more charge cycles of a battery. The first charging method includes a first voltage charging level and the second charging method includes a second voltage charging level that is higher than the first charging level. | 06-21-2012 |
20120249053 | BATTERY CHARGING SYSTEM FOR NOTEBOOK COMPUTER - The apparatus includes an AC adapter input, a battery charger coupled to the input to charge a battery, a temperature sensor, and system logic to execute code stored on storage devices. The battery charger provides a charging current that is a function of temperature sensed by the temperature sensor. The charging current may also be a function of sensed barometric pressure, battery age, external temperature, a full charge capacity, and system power demand. | 10-04-2012 |
20120286741 | FAST BATTER CHARGING SYSTEM AND METHOD - A system and method includes detecting whether a fast charger is coupled to a system having a processor and a memory, providing current to a battery from an internal charger circuit if no fast charger is detected, and providing current to the battery from the fast charger if the fast charger is detected. | 11-15-2012 |
20120299532 | FAST CHARGING SYSTEM AND METHOD - A system and method include detecting whether a fast charger module is coupled to a system having a processor and a memory device. If the fast charger module is coupled to the system, a fast charging current is provided from the fast charger module at multiple selectable voltage levels via an internal charger. If the fast charger module is not detected as coupled to the system, a charging current is provided from an AC adapter via the internal charger. | 11-29-2012 |
20140167699 | BATTERY CYCLING AND MANAGEMENT - An aspect provides a method, including: setting a battery pack, in an information handling device having two or more battery packs, as a priority battery pack; discharging the priority battery pack and maintaining one or more other battery packs in an idle state; ascertaining if the priority battery pack satisfies one or more conditions; and in response to the priority battery pack satisfying the one or more conditions, setting one of the one or more other battery packs to be the priority battery pack and maintaining the remaining battery packs in an idle state; wherein the priority battery pack is prioritized in terms of charging. Other aspects are described and claimed. | 06-19-2014 |
