ABSTRACT:
A method includes determining that a battery has entered a transition phase based on the occurrence of a change in direction of current flow through the battery. In response to determining that the battery is in the transition phase, a capacity of the battery is determined based on a transition phase battery capacity model of capacity-vs.-voltage.
