초록

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...
