Simulation Analysis of Different Battery Boxes Under Shock Condition
With the continuous development of the new energy industry,lithium-ion batteries are increasingly widely used in electric vehicles,in this context,the development of new energy,reduce the proportion of fuel vehicles,for the current national de-velopment strategy and reduce the use of non-renewable energy such as oil is of great significance,and the safety of new energy bat-teries urgently needs to be solved.In this paper,through the modeling of SolidWorks,three different arrangement methods are de-signed for the battery cells in the battery box,and three different arrangement of cell modules and corresponding battery bottom plates are constructed,namely long mode,positive mode and clip type.After simplifying the model,Ansys is used to simulate and analyze the three battery substrates to determine their stress under impact conditions,so as to provide suggestions for the design of the battery box.The results show that the deformation of the internal cell module of the battery base plate of the long-mode and posi-tive-mode new energy vehicles is the most obvious after the force is applied on the long side,and the clip type has the most obvious deformation in the corner and middle position although it performs better in the length and width.It can be seen that optimizing the length and width of the battery base plate and the thickness of the clip-on box can improve the safety performance of new energy ve-hicles.It provides a reference for the arrangement of cells in battery boxes and applications designed for electric vehicles.
