    • A system (200) includes a battery charger (278) and a battery (202). The battery (202) includes a thermistor (230), a voltage identifying element (240), a switch (244), a memory device (232), and a battery data contact (228), connected to a data port of the memory device (232) and the voltage identifying element (240). The voltage identifying element (240) determines a voltage that controls the switch (244). When the switch (244) is enabled, the thermistor (230), connected to a battery clock contact (224), is active and a microprocessor (102) on the battery charger (278) reads the value of the thermistor (230) via an analog-to-digital converter. When the switch (244) is disabled, the thermistor (230) is switched out and the battery clock contact (224) is used to clock the memory device (232). The battery charger (278) has a data contact (226) for receiving the battery data contact (228) and a clock contact (222) for receiving the battery clock contact (224). The battery charger (278) further includes at least two switches (204,206), and the microprocessor (102) is programmed to selectively operate the switches (204,206).
    • 系统(200)包括电池充电器(278)和电池(202)。 电池(202)包括连接到存储器的数据端口的热敏电阻器(230),电压识别元件(240),开关(244),存储器设备(232)和电池数据触点(228) 装置(232)和电压识别元件(240)。 电压识别元件(240)确定控制开关(244)的电压。 当开关(244)被使能时,连接到电池时钟触点(224)的热敏电阻(230)被激活,并且电池充电器(278)上的微处理器(102)通过 一个模数转换器。 当开关(244)被禁用时,热敏电阻(230)被切断并且电池时钟触点(224)被用于为存储器件(232)提供时钟。 电池充电器(278)具有用于接收电池数据触点(228)的数据触点(226)和用于接收电池时钟触点(224)的时钟触点(222)。 电池充电器(278)还包括至少两个开关(204,206),并且微处理器(102)被编程为选择性地操作开关(204,206)。
