At the last, the static strength analysis is carried out on the battery box. By analyzing the modal characteristics and the harmonious response to vibration characteristics of the battery box, the dynamic performance of the battery box has been comprehensively mastered.
By analyzing the modal characteristics and the harmonious response to vibration characteristics of the battery box, the dynamic performance of the battery box has been comprehensively mastered. Finally, based on the static and dynamic analysis results of the battery box, the weak points and unreasonable points are improved.
Finally, based on the static and dynamic analysis results of the battery box, the weak points and unreasonable points are improved. The results show that the modified model has a good improvement effect and has basically reached the established design requirements, which verifies the rationality of the structural improvement scheme.
For the battery pack structure grid, it belongs to a multi degree of freedom vibration system, where each grid unit represents one degree of freedom. Due to the possible number of grid cells reaching millions, the system also has a lot of degrees of freedom.
This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.
