Embodiment
[0209] Take the design of a structure containing 25 18650 lithium-ion power battery packs as an example:
[0210] Power battery structure such as Figure 8 As shown, the overall size of the structure is 18cm×18cm×6.5cm, and 25 power batteries are evenly distributed in the cylinder; the power battery pack structure is made of aluminum alloy, and the heat-conducting silica gel sheet filled between the battery and the structure functions as insulation, heat conduction, and buffer And so on.
[0211] The overall flow of the power battery pack structure design method is as follows: figure 1 As shown, the specific steps are as follows:
[0212] refer to figure 2 , determine the structural design process of the power battery pack, starting from step S200:
[0213] Step S201: the number of discrete units in the x-axis direction and the y-axis direction of the flat plate with a size of 18cm×18cm is 90;
[0214] Step S202: the filtering radius is set to 2.1;
[0215] Step S203: t...
