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.
