摘　　要：目前锂离子蓄电池缺少有效的可靠性验证和评估方法,本文针对该问题,结合型号应用经验,分析和研究了对锂电池产品开展无模型可靠性增长试验的方案和基于试验数据进行可靠性评估的方法。本文主要对试验时间计算、应力施加、和配套充放电设备的使用等锂电池可靠性增长试验中,不同于其他产品的要点进行了探讨和研究。此外,锂电池组由不同形式的单体串并联而成,因此在基于试验数据的可靠性评估上,本文探讨了对单体进行可靠性增长试验后,通过可靠性建模等方法进一步对锂电池组进行可靠性评估的工程可行方案。本文可为锂电池产品进行可靠性验证和评估提供思路。The single-used lithium ion battery is lack of effective method for the reliability verification and assessment now.So combined with the experience of the other electronic products in reliability growth test without models,the paper studied the key points in the scheme design for lithium battery products reliability growth test.The research includes total test time calculation,definition of electrics stress and other conditions in test,test results evaluation,and the battery pack reliability evaluation from the battery cell.The paper can provide ideas for lithium battery products reliability verification and evaluation.
