  • Patent number: 8589098
    Abstract: An electrical device is powered by a battery. The device includes transition phase determining circuitry operatively connected to the battery to determine that the battery has entered a transition phase based on the occurrence of a change in direction of current flowing through the battery. Battery capacity determining circuitry is operatively connected to the transition phase determining circuitry and configured to determine, in response the transition phase determining circuitry determining that the battery is in the transition phase, a capacity of the battery based on a transition phase battery capacity model of capacity-vs.-voltage. The transition phase determining circuitry is further configured to determine an end of the transition phase based on the transition phase battery capacity model and a non-transition battery capacity model of capacity-vs.-voltage yielding the same capacity value for a given measured voltage of the battery.

  • Patent number: 7676335
    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.

  • Patent number: 7107161
    Abstract: A method and a system for accurately reporting battery capacity that do not rely on a coulomb counter are disclosed herein. The method comprises the steps of determining if the battery is in a transition phase and determining the battery capacity based on a transition phase battery capacity model when the battery is in the transition phase. The transition phase occurs upon one of attachment of the battery to a power source and disconnection of the battery from the power source. The behaviour described by the transition phase battery capacity model approaches the behaviour of real transition phase battery capacity so as to minimize the error of the determined battery capacity. The method and system accurately report battery capacity during a transition phase from discharging to charging and a transition phase from charging to discharging.
