Circuits, apparatuses, electrochemical device charging methods, and lithium-mixed
metal electrode cell charging methods are provided. According to one aspect, a
circuit includes charging circuitry adapted to apply electrical energy to an electrochemical
device to charge the electrochemical device, and the electrochemical device being
configured to assume an open-circuit condition in a substantially charged state;
shunting circuitry electrically coupled with the charging circuitry and configured
to shunt the electrical energy around the electrochemical device responsive to
the electrochemical device reaching the substantially charged state; and indication
circuitry configured to output a signal responsive to the shunting of the electrical
energy to indicate a charge status of the electrochemical device.
