20090230923 | Battery management circuit - A non-rechargeable battery includes a housing with an opening and a cover that closes the opening in the housing. The housing and the cover define a volumetric region within the battery. The battery also includes at least one electrochemical cell and a management component, both located in the volumetric region. The management component includes programmable electrical circuitry that selectively interrupts electrical current output from the cell out of the battery based on an actively monitored state of the battery. The chemistry of the battery is Li—FeS | 09-17-2009 |
20090291332 | System and Method of Controlling Fluid to a Fluid Consuming Battery - A fluid regulating system is provided for controlling fluid to a fluid consuming battery having a fluid consuming cell. The fluid regulating system includes a valve and an actuator for opening and closing the valve. The actuator is controlled to open the valve when greater battery electrical output is required and to close the valve when lesser battery electrical output is required to operate a device. A controller controls operation of the actuator to open and close the valve based on a monitored rate of change in electrical output, such as voltage, compared to a rate of change threshold, wherein the valve is opened when the monitored rate of change exceeds the threshold. | 11-26-2009 |
20090291334 | System and Method of Controlling Fluid to a Fluid Consuming Battery - A fluid regulating system is provided for controlling fluid to a fluid consuming battery having a fluid consuming cell. The fluid regulating system includes a valve having a moving plate disposed adjacent to a fixed plate, and both having fluid entry ports to open and close a valve. The fluid regulating system also includes an actuator for moving the moving plate to open and close the valve. The actuator is controlled to open the valve when greater battery electrical output is required to operate a device and maintains the valve in the open position for a minimum required time to minimize battery capacity loss due to operation of the fluid regulating system. | 11-26-2009 |
20100124687 | Fluid Manager Having Fluid Injection Primer for a Fluid Consuming Battery - A fluid consuming battery is provided that includes a fluid (e.g. air) manager for supplying fluid to the battery. The fluid manager includes a housing member defining a plenum in fluid communication with a fluid consuming electrode of a fluid consuming battery cell. The fluid manager also includes a fluid injection primer in fluid communication with the plenum for injecting fluid into the plenum. The fluid injection primer includes a manually operated air mover that moves upon user actuation to inject fluid into the plenum to the fluid consuming electrode of the battery cell. Additionally, a valve and an actuator may be provided for opening and closing the valve in response to a controller. | 05-20-2010 |
20100124688 | Regulator Valve for a Fluid Consuming Battery - A regulator is provided for supplying fluid, e.g., air, to a fluid consuming battery. The regulator includes a valve housing adapted to be in fluid communication with a fluid consuming electrode of a fluid consuming battery cell. The valve housing has an opening. The regulator also includes a valve member disposed in the opening of the housing and configured to move axial relative to the housing between an open valve position and a closed valve position, wherein fluid is able to pass to the fluid consuming electrode in the open valve position. | 05-20-2010 |

20110121790 | Staggered Multi-Battery Battery Charging - A battery charging method includes generating a plurality of charge profiles, each for a different one of a plurality of batteries, wherein a charge profile indicates a charge current as a function of charge time, and at least two of the charge profiles have a different charge current at a same charge time, and concurrently charging each of the plurality of batteries based on a corresponding charge profile. | 05-26-2011 |
20110274997 | Device Having Fluid Consuming Battery and Fluid Manager - An electronic device having a battery compartment sized to receive one or more fluid consuming batteries is provided. The device includes one or more fluid entry ports, which can be in the cover of the battery compartment. A fluid flow restrictor is compressed between the fluid entry ports in the device and the fluid entry ports in the fluid consuming battery such that a rate of flow of fluid from outside the device to the battery's fluid consuming electrode is controlled by a compressed portion of the fluid flow restrictor. The fluid flow restrictor can include a foam material. A seal can also be provided at or near the periphery of the fluid flow restrictor; the seal can be a more highly compressed portion of the fluid flow restrictor or a separate component such as an O-ring seal. | 11-10-2011 |
