摘要： A charge stored in a battery is estimated by multiplying estimated charge currents supplied during charge phases and estimated discharge currents discharged during operational modes by the respective amounts of time of charging and discharge. The state of charge of the battery is calculated from the estimated stored charge. Furthermore, parameters of the battery may be measured to be used to adjust the estimated state of charge of the battery. In a first case, the estimated stored charge may be adjusted to a charge value corresponding to the detected completion of a constant current charge phase. In a second case, the estimated stored charge may be adjusted to a charge value corresponding to the detected completion of a constant voltage charge phase. In a third case, the estimated stored charge may be adjusted to a charge value corresponding to a detected predetermined discharge level of the battery.

摘要： Methods and systems for power and charging control in a Bluetooth headset are disclosed and may include measuring a load current during charging of batteries in a mobile device. A completion time of the charging may be predicted. The charging may be terminated based on a sum of the load current and a known charge complete threshold current of the batteries, which may include lithium batteries. A current or voltage source may be controlled for the charging. A current from the current source may be compared to the sum via a current comparator. A rate of charging may be controlled for charging to a desired end voltage based on the predicted completion time. A user preference based on the predicted completion time may be stored, where the user preference may be utilized to control one or more subsequent charges.

摘要： An electronic device includes a rechargeable battery, an electrical circuit, a battery safety circuit, and a power down mode circuit. The electrical circuit is configured to generate a power mode control signal. The power down mode circuit receives the power mode control signal. If the power mode control signal has a first value, the power down mode circuit is configured to force a voltage at a first port of the battery safety circuit to a voltage value that is less than an under voltage lock out (UVLO) threshold value of the battery safety circuit to transition the electronic device from a normal operating mode to a low current power down mode. The electronic device may further include a wake up mode circuit.
