Abstract
A method for charging a battery includes (a) applying a charging current pulse to the battery, (b) after the step of applying the charging current pulse to the battery, measuring a first voltage across the battery, (c) estimating an equilibrium voltage of the battery, (d) determining a Nernst voltage of the battery from a difference between the first voltage and the equilibrium voltage, and (e) controlling charging of the battery at least partially based on the Nernst voltage.
