摘要
0.2It放电容量是移动电话用锂离子电池的一项重要测试,按照GB/T 18287-2013《移动电源用锂离子蓄电池及蓄电池组总规范》标准要求,对移动电话用锂离子电池进行0.2ItA放电容量进行测试,然后分别建立A类标准不确定度计算模型和B类标准不确定度计算模型,其中模型B综合考虑了电压测量、电流测量、时间测量误差对不确定的影响,最后对两种模型的计算结果进行分析比较。
0.2It Discharge capacity is an important test of lithium-ion batteries for mobile phones.0.2It Discharge capacity of lithium-ion batteries for mobile phones is tested by GB/T 18287-2013,and then the calculation models of Type A standard uncertainty and Type B standard uncertainty are established respectively.The Type B standard uncertainty considers the inf luence of voltage measurement,current measurement and time measurement error on uncertainty.The calculation results of the two models are analyzed and compared.
