Abstract
A method includes monitoring the voltage of a power source connector for charging a battery. A determination is made that the battery has entered a transition phase based on sensing an abrupt change in the voltage. 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 that defines the battery's capacity as a function of the battery's voltage.
