    • A system for charging a battery over a linear or nonlinear circuit. The system includes a first mechanism for receiving a feedback signal and providing a charging signal to the battery over a first electrical path when the feedback signal indicates that the battery is not fully charged. A second mechanism measures a voltage state of the battery via second and third electrical paths and provides the voltage state as the feedback signal to the first mechanism in response thereto. The voltage state accounts for voltage drops occurring over the circuit. In the specific embodiment, the first mechanism is a controllable power supply and the second mechanism is a sensing circuit. The sensing circuit includes a subtractor circuit that subtracts the voltage on the second electrical path from the voltage on the third electrical path and provides the feedback signal in response thereto. The second electrical path includes a wire connected between a first terminal of the subtractor circuit and a positive terminal of the battery. The second electrical path also includes a first sensing resistor connected between an output of the power supply and the first terminal of the subtractor circuit. The third electrical path includes a wire connected between a second terminal of the subtractor circuit and a negative terminal of the battery. The third electrical path also includes a second sensing resistor connected between a ground and the second terminal of the subtractor circuit.
    • 一种用于通过线性或非线性电路对电池充电的系统。 该系统包括第一机构,用于当反馈信号指示电池未完全充电时,接收反馈信号并通过第一电气路径向电池提供充电信号。 第二机构经由第二和第三电气路径测量电池的电压状态,并且响应于此向第一机构提供作为反馈信号的电压状态。 电压状态考虑了电路上发生的电压降。 在具体实施例中,第一机构是可控电源,第二机构是感测电路。 感测电路包括减法器电路,其从第三电路上的电压减去第二电路上的电压,并响应于此提供反馈信号。 第二电路包括连接在减法器电路的第一端子和电池的正极端子之间的导线。 第二电路还包括连接在电源的输出端和减法器电路的第一端子之间的第一感测电阻器。 第三电路包括连接在减法器电路的第二端子和电池的负极端子之间的导线。 第三电路还包括连接在减法器电路的地和第二端之间的第二检测电阻。

    • The battery charging process monitors the battery charging pockets waiting for an indication that a battery or a phone-battery combination has been inserted into their respective pockets. The first battery that is inserted is the high priority battery and is charged first while any subsequent battery inserted into a charging pocket has no power applied until the high priority battery is charged. If the phone enters a call while in the charger, it becomes the high priority battery if it was not already. In this case, power is removed from the individual battery and applied to the phone-battery combination until the call has been completed. At this point, the process returns the high priority status to the battery that had it prior to the call interrupt.
    • 电池充电过程监视电池充电口袋,等待电池或手机电池组合已插入其相应口袋中的指示。 插入的第一个电池是高优先级电池,并且首先充电,而任何后续的电池插入充电口袋中,直到高优先级电池充电才有效。 如果手机在充电器中进入通话状态,那么如果手机尚未成为高优先级电池。 在这种情况下,电源从单个电池中移除并应用于手机 - 电池组合,直到通话完成。 此时,该处理将高优先级状态返回给具有呼叫中断之前的电池。
