Analysis on the testing techniques of cranking performance of lead-acid battery

起动性能是汽车用铅蓄电池的关键技术指标,在国内外标准中都规定了严格的测试方法与判定要求。对铅蓄电池起动性能测试中的重要参数,如起动电流、端电压、放电时间与温度进行了详细分析,按照标准中规定的技术测试条件研究了检测过程中需要注意的诸多重要影响因素与及相应的解决方法,为保证测试数据的准确性与做出合理的结果判定起到了重要作用。

Cranking performance is an important technical characteristic of lead-acid starter batteries used in the automobiles. In the national and international standards, the test conditions, methods and requirements are clearly described. In this paper, the key parameters including cranking current, terminal voltage, discharge time and test temperature of cranking performance test were analyzed in detail and the impact of main factors which should be paid attention to in the test procedure were investigated. Then the suggestions and solutions to avoid these adverse effects were given which played an important role in ensuring the accuracy of test data and rationality of test results.
