    • The invention concerns a method (300) and system (100) for selectively charging a battery (112). In one arrangement, the method can include the steps of coupling (311) the battery to a first power supply (114), coupling (311) the battery to a second power supply (116), determining (312) an available charging current parameter for the battery and selectively enabling (314) a charging circuit (120) for the first power supply and a charging circuit (122) for the second power supply based on the available charging current parameter of the battery. The selectively enabling process can be based on maximizing (316) an available charging current of the battery and minimizing (320) a power dissipation of the battery. As an example, the first power supply can be a hard-wired charger (114), and the second power supply can be a wireless charger (116).
    • 本发明涉及用于为电池(112)选择性充电的方法(300)和系统(100)。 在一种布置中,该方法可以包括将电池耦合(311)到第一电源(114),将电池耦合(311)到第二电源(116),确定(312)可用充电电流参数 以及基于电池的可用充电电流参数选择性地启用(314)用于第一电源的充电电路(120)和用于第二电源的充电电路(122)。 选择性启用过程可以基于使电池的可用充电电流最大化(316)并且使电池的功耗最小化(320)。 作为示例,第一电源可以是硬线充电器(114),并且第二电源可以是无线充电器(116)。

    • A protection circuit (100) for use with a battery operated device (50) which includes an over temperature detector (110), a controller (130), and a voltage divider circuit (102 and 106). The voltage divider circuit includes a multi-use thermistor (102) for monitoring a temperature of a battery cell (104), a battery charger, or a battery operated device. Further, the thermistor can be operatively connected to the over temperature detector. An input voltage at the input (114) of the over temperature detector can vary relative to a variance in the monitored temperature. The temperature detector can signal the controller to terminate the charging of the battery cell if the temperature exceeds a predefined value. The device discharge detector can signal the controller to terminate the discharging of the battery cell if the battery operated device determines a specific event such as water intrusion, circuit failure or a software problem.
    • 一种与电池驱动装置(50)一起使用的保护电路(100),其包括过温度检测器(110),控制器(130)和分压器电路(102和106)。 分压器电路包括用于监视电池单元(104),电池充电器或电池供电装置的温度的多用热敏电阻(102)。 此外,热敏电阻可以可操作地连接到过温度检测器。 过温度检测器的输入端(114)处的输入电压可以相对于所监视温度的变化而变化。 如果温度超过预定值,温度检测器可以通知控制器终止电池单元的充电。 如果电池供电装置确定特定事件,例如水入侵,电路故障或软件问题,装置放电检测器可以通知控制器终止电池单元的放电。
