Study on Chaotic of Discharge Voltage of Parallel Power Battery for Electric Vehicles
To understand the discharge voltage chaos mechanism of the parallel battery pack of electric vehicles,master the non-linear law of discharge,provide theoretical basis for the study of battery discharge mechanism and im-prove the experience and blindness of the battery pack equalization and difference fault warning,we established a model for parallel battery pack and verified it by experiments.Based on the chaos theory,the chaotic rules of dis-charge voltage of parallel battery pack were studied.The following conclusions can be drawn:the chaotic phenomenon can be occurred in the power battery,but not the hyperchaotic phenomenon;The chaotic condition is caused by the short-term effect of the battery;The chaotic behavior has a negative effect on the battery system which is needed to be suppressedtheoretically,and thechaotic occurrence time during the discharge of parallel battery pack is affected by the cause of the battery packinconsistent;The priority of parallel battery equalization and battery difference fault warning is different because of different reasons.
