A novel complex equivalent circuit model has been proposed for the lithium-ion batteries. The lithium-ion battery pack capacity check method is proposed, which is based on the balance charge and serial-discharge mechanism, aiming to realize the aeronautical battery pack capacity fading and safety judgment. The method achieves the battery pack capacity check and safety anticipation maintenance by recycling balance charge and serial discharge process together with the minimum mean square error method. Experimental results show that, the method can effectively realize the capacity check and security anticipation and the accurate rate is over than 95%. The proposed capacity inspection and safety anticipation method can effectively solve the aeronautical lithium-ion battery pack capacity security prediction problem, effectively ensuring its cruising ability and security in the aero power supply applications.
