Abstract: A battery monitoring apparatus that senses battery conditions such as low battery charge, end of battery capacity, and end of battery life, and responds by taking actions such as sending messages to a remote site and/or powering down. A rechargeable battery is coupled to one or more power-consuming electrical components, including battery monitoring equipment. The battery monitoring equipment senses battery charge. In response to a low-battery-charge condition, the battery monitoring equipment transmits a battery status message to a remote site and powers-down some of the electrical components. Whenever the battery nears the end of its capacity, the monitoring equipment powers down all electronic components and awaits the application of external power. The invention also tracks the time required for the battery charge to deplete. Charge duration decreases over time, and whenever it reaches a predetermined minimum, the battery monitoring equipment transmits a representative status message to the remote site.

Abstract translation: 一种电池监视装置，其检测诸如电池电量低，电池容量结束和电池寿命终止的电池状况，并且通过采取诸如向远程站点发送消息和/或断电等动作进行响应。 可充电电池耦合到一个或多个耗电量的电气部件，包括电池监视设备。 电池监控设备检测电池电量。 响应于电池电量低的状况，电池监控设备将电池状态消息发送到远程站点并断电一些电气组件。 每当电池接近电池容量时，监控设备将关闭所有电子元件并等待外部电源的应用。 本发明还跟踪电池充电耗尽所需的时间。 充电持续时间随着时间的推移而减少，并且每当其达到预定的最小值时，电池监视设备向远程站点发送代表状态消息。
