    • A system and method for testing a battery having an internal impedance by generating digital battery parameter values corresponding to the battery parameters at different points in time by means of current, voltage and temperature measurement circuits and an analog-to-digital converter. An electrical load is periodically placed on the battery and the battery is also charged between loadings in order to provide battery parameter values during different battery conditions. A microprocessor coordinates the testing of the battery and the measuring of the battery parameter values, as well as the calculation of test criteria based on those values in order to quickly and accurately analyze the condition of the battery.
    • 一种用于通过利用电流,电压和温度测量电路以及模拟 - 数字转换器在不同时间点生成对应于电池参数的数字电池参数值来测试具有内部阻抗的电池的系统和方法。 周期性地将电负载放置在电池上,并且电池在负载之间也被充电,以便在不同电池条件期间提供电池参数值。 微处理器协调电池的测试和电池参数值的测量,以及基于这些值的测试标准的计算,以便快速准确地分析电池的状况。
