Green Packaging Design and Drop Simulation Test of Cylindrical Power Lithium Battery

目的对圆柱形的车用动力锂电池进行运输包装设计及跌落仿真试验分析。方法运用运输包装设计五步法,根据产品特性、运输包装要求与流通环境条件,分析现有包装的不足,提出包装解决方案,并依据包装设计方案设计包装材质、结构尺寸,对设计的包装进行强度校核,最后对包装件进行跌落仿真试验,分析和评价所设计的包装方案。结果设计的运输包装解决方案分为内外包装两部分,内包装使用材质为EPE发泡聚乙烯塑料材料,结构为多孔结构,外包装使用的材质为C楞瓦楞纸板,结构为0201型箱型结构,对所设计的包装方案进行底面跌落模拟仿真试验,锂电池产品所受到的最大等效应力值为5.865 MPa,低于圆柱形动力锂电池材料的许用应力值132.2 MPa。结论所设计的圆柱形动力锂电池运输包装方案合理,对锂电池类危险品的运输包装设计具有一定的借鉴意义。

The work aims to conduct transportation packaging design and drop simulation test analysis of cylindrical lithium batteries for vehicle power.By using the five-step method of transportation packaging design,according to the product characteristics,transportation packaging requirements and circulation environment conditions,the shortcomings of existing packaging were analyzed.Packaging solutions were put forward.And the packaging materials and structural dimensions were designed according to the packaging design scheme.The strength of the designed packaging was checked.At last,the drop simulation test on the packaging pieces was conducted and the designed packaging scheme was analyzed and evaluated.The designed transportation packaging solution consisted of two parts:inner and outer packaging.The inner packaging was made of EPE foamed polyethylene plastic material with porous structure,and the outer packaging was made of C corrugated cardboard with 0201 box structure.The bottom drop simulation test of the designed packaging solution showed that the maximum equivalent stress of lithium battery products was 5.865 MPa,which was lower than the allowable stress of cylindrical power lithium battery materials of 132.2 MPa.The transportation packaging scheme of cylindrical power lithium batteries is reasonable,which has certain guiding significance for the transportation and packaging design of dangerous goods such as lithium batteries.
