The measured capacity at the end of the accelerated overcharge will be compared to the initial capacity in order to determine capacity fade. The internal impedance is measured at two different loads which will be made after each phase in order to observe how it changes with time. 检测电池的原始性能。快速充满后的标准容量与最初容量进行对比判断容量衰减。为了观察内阻随时间的变化情况，在完成每一个测试步骤后，将会在两种不同的负载下测试内阻。Procedure: 过程Testing starts with a residual discharge (cycle 1) 对残余容量进行放电（循环1）Charging is performed with a constant current of C/10 A for 16h in accordance with IEC61951-2.
