    • A portable electronic device employs a method for recovering power to a rechargeable battery used therein when the battery is in a low state of charge. The portable electronic device includes at least a power management subsystem (PMS), a main processor subsystem, and the battery. When the battery is incapable of supplying boot-up power to the processor subsystem, power is provided from a battery charger to the PMS to power-up the PMS. The PMS then determines the battery's type and a state-of-charge (SOC) parameter for the battery, and compares the SOC parameter to a threshold, which is based on at least the battery type. If the SOC parameter is less than the threshold, power is provided from the battery charger to the battery for use in recharging the battery. Otherwise, power is supplied from the battery to the processor subsystem to facilitate general operation of the portable electronic device.
    • 当电池处于低电荷状态时,便携式电子设备采用一种用于恢复其中使用的可再充电电池的电力的方法。 便携式电子设备至少包括电源管理子系统(PMS),主处理器子系统和电池。 当电池不能向处理器子系统提供启动电源时,从电池充电器向PMS提供电源以加电PMS。 然后,PMS确定电池的电池类型和充电状态(SOC)参数,并将SOC参数与至少基于电池类型的阈值进行比较。 如果SOC参数小于阈值,则从电池充电器向电池供电,以便为电池充电。 否则,电力从电池供应到处理器子系统以便于便携式电子设备的一般操作。

    • A method and apparatus for charging a rechargeable battery (110) that takes into account the use patterns of the particular battery. A user may only discharge the battery a little and recharge it frequently which is a low capacity high life cycle use pattern, or discharge the battery almost completely and place the battery on charge less frequently indicating a high capacity low life cycle use pattern. Herein, a battery is installed in an electronic device wherein a battery discharge determination circuit and a discharge determination algorithm determine the discharge level of the battery when a charging circuit is placed on the battery. The measurement algorithm determines from the rechargeable battery discharge level measurement how to recharge the rechargeable battery. The measurement algorithm may also determine how to recharge the rechargeable battery based on a plurality of previous measurements stored either in the electronic device or the battery.
    • 一种用于对可充电电池(110)进行充电的方法和装置,其考虑了特定电池的使用模式。 用户只能稍微放电一次,并且频繁充电,这是一个低容量的高生命周期使用模式,或者几乎完全放电电池,并将电池放电较少,表明高容量的低寿命周期使用模式。 这里,电池被安装在电子装置中,其中当充电电路放置在电池上时,电池放电确定电路和放电确定算法确定电池的放电水平。 测量算法从充电电池放电水平测量确定如何对可充电电池充电。 测量算法还可以基于存储在电子设备或电池中的多个先前测量来确定如何对可充电电池进行充电。
