  • Method and system for energy storage capacity estimation of battery cells
    Patent number: 9360530
    Abstract: 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.

  • Residual life indicating system
    Patent number: 7201036
    Abstract: A residual life indicating system for a filter includes a main filter, a sampling filter, and a sensor. Both the main filter and the sampling filter receive an ambient gas meant to be filtered. The sensor connects to the sampling filter and senses the presence of a predetermined chemical in the gas that has been filtered by the sampling filter.
