    • An electronic battery tester for testing a storage battery. The tester includes a first connector configured to electrically couple to a first terminal of the battery via a first battery post adapter and a second connector configured to electrically couple to a second terminal of the battery via a second battery post adapter. The tester also includes an input configured to receive a battery-post-adapter-connection indicator. Test circuitry, which is coupled to the input, upon receipt of the battery-post-adapter-connection indicator, determines whether or not the first battery post adapter and the second battery post adapter are faulty.
    • 用于测试蓄电池的电子电池测试仪。 测试器包括第一连接器,其被配置为经由第一电池柱适配器电耦合到电池的第一端子,以及第二连接器,其被配置为经由第二电池柱适配器电耦合到电池的第二端子。 测试器还包括配置为接收电池后适配器连接指示器的输入。 在接收到电池后适配器连接指示器时耦合到输入端的测试电路确定第一电池适配器和第二电池适配器是否有故障。

    • A method and apparatus for simulating a battery tester with a fixed resistance load, such as a widely used Japanese load tester that rates the strength of Japanese batteries that are categorized under the Japanese Industrial Standard (JIS), are provided. This invention simulates such a device without invoking large current loads, yields familiar results, utilizes an existing database and provides more conclusive testing. The method includes estimating a battery load test voltage as a function of a measured battery dynamic parameter, an open circuit voltage, the load resistance value of the load tester and the battery temperature. A bounceback voltage (BBV) of the battery is also predicted. The BBV, load voltage and battery temperature are utilized to rate the strength of the battery. Also, to improve the accuracy of test results for a substantially discharged battery, one embodiment projects the results of recharging discharged batteries without actually doing so.
    • 提供了一种用于模拟具有固定电阻负载的电池测试器的方法和装置,例如广泛使用的日本负载测试仪,其对按照日本工业标准(JIS)分类的日本电池的强度进行评估。 本发明模拟这种设备而不调用大的电流负载,产生熟悉的结果,利用现有的数据库并提供更确定的测试。 该方法包括根据测量的电池动态参数,开路电压,负载测试器的负载电阻值和电池温度来估计电池负载测试电压。 还预测了电池的反弹电压(BBV)。 利用BBV,负载电压和电池温度来评估电池的强度。 此外,为了提高基本放电的电池的测试结果的准确性,一个实施例投射了对放电电池再充电的结果,而实际上并不这样做。
