求大牛開導(dǎo),為什么NASA的電池循環(huán)容量數(shù)據(jù)有躍升現(xiàn)象 已有3人參與

最近在分析NASA的電池數(shù)據(jù),發(fā)現(xiàn)隨著循環(huán)電池容量并不是單調(diào)下降的,而是在一些點會有躍升現(xiàn)象。求大牛開導(dǎo)一下這樣的原因和機理! nasa1.jpg |

隨手搜了幾個用這個數(shù)據(jù)集的幾個論文: Li F, Xu J. A new prognostics method for state of health estimation of lithium-ion batteries based on a mixture of Gaussian process models and particle filter[J]. Microelectronics Reliability, 2015, 55(7):1035-1045. Mo B, Yu J, Tang D, et al. A remaining useful life prediction approach for lithium-ion batteries using Kalman filter and an improved particle filter[C]// IEEE International Conference on Prognostics and Health Management. 2016:1-5. 好像大家都是直接把數(shù)據(jù)拿來用的,而我比較疑惑的是這樣的現(xiàn)象出現(xiàn)的原因,不知道誰能解釋一下。。。 |

Data Description: A set of four Li-ion batteries (# 25, 26, 27 and 28) were run through 3 different operational profiles (charge, discharge and impedance) at room temperature (24 deg C). Charging was carried out in a constant current (CC) mode at 1.5A until the battery voltage reached 4.2V and then continued in a constant voltage (CV) mode until the charge current dropped to 20mA. Discharge was carried out using a 0.05Hz square wave loading profile of 4A amplitude and 50% duty cycle until the battery voltage fell to 2.0V, 2.2V, 2.5V and 2.7V for batteries 25, 26, 27 and 28 respectively. Impedance measurement was carried out through an electrochemical impedance spectroscopy (EIS) frequency sweep from 0.1Hz to 5kHz. 這是數(shù)據(jù)的描述 |
