Condition Tester For A Battery
US Patent:
5627472, May 6, 1997
Filed:
Jan 26, 1995
Appl. No.:
8/378688
Inventors:
David Ofer - Newton MA

Assignee:
Duracell Inc. - Bethel CT
International Classification:
G01N 27416, G01R 3136
US Classification:
324435
Abstract:
A tester for determining the condition of an electrochemical power source, e. g. a battery or main cell, is disclosed. The tester may comprise an electrolytic (coulometric) cell connected in series to a auxiliary cell. The auxiliary cell is a miniature electrochemical power cell. The electrolytic (coulometric) cell may have no electromotive force of its own and may comprise an anode and cathode of the same material, desirably silver, with an electrolyte contacting at least a portion of both the anode and cathode. The tester may be permanently connected in parallel to a main cell being tested and is thin enough to be integratable into a label for the main cell. As the main cell discharges, the electrolytic cell anode clears proportionally to the discharge of one of the electrodes of the main cell to provide a continuous visually discernible indication of the state of charge of the main cell.

Filed:
Jan 20, 2009
Appl. No.:
12/356151

Assignee:
SOLARONE SOLUTIONS LLC - Framingham MA
International Classification:
G06F 17/00
US Classification:
705412
Abstract:
A method for optimizing an LED lighting system cost includes steps of determining LED costs, power source costs, and total costs associated with a plurality of LED quantities, and identifying a lowest total cost as an optimal cost. A LED lighting system includes an LED operated by a constant-current driver at less than its maximum current capacity. A programmable controller including a feedback routine is used to compensate for intensity drift as an LED ages. Other embodiments of LED lighting systems include multiple LEDs producing light having various spectrums to optimize the lighting system efficiency and the effectiveness. A charge controller including an MPPT routine is advantageously employed with a LED lighting system powered by a limited-capacity power source.
