基于半经验法的锂离子电池衰减模型
Decay Model of Lithium-ion Battery Based on Semi-empirical Method
摘要
Abstract
On the basis of considering the multi-factors model,combined with the solid electrolyte interface(SEI)film forma-tion mechanism,a semi-empirical lithium-ion battery life decay model is proposed.Taking graphite/LiFePO4(LFP)lithium-ion bat-tery as the research object,the parameters of the model are tuned using battery degradation data.Based on the proposed model,the accuracy of the prediction of capacity degradation by different decay models under certain operating conditions is experimentally ver-ified.The results show that the proposed model fits the battery fade data well,and the estimation error of the battery capacity degrada-tion can be kept within 3%.关键词
