6 FAQs about [Battery Pack Finite Element Analysis]
How do you model a battery pack based on a finite element?
Finite Element Modeling Process. Firstly, prepare the model, create a model based on the geometric shape and material characteristics of the battery pack, divide the battery pack into discrete finite element elements, and define the nodes and connection relationships of each finite element element element.
What is the design optimization of battery pack enclosure?
The design optimization of battery pack enclosure considers the performance improvement as its objectives, such as minimizing the maximum deformation along the loading direction, maximizing the minimum natural frequency resulting from the vibrations and minimizing its mass.
How to evaluate natural frequency of battery pack enclosure?
The notion behind evaluation of natural frequencies of battery pack enclosure is to check if these are in the range of 7–200 Hz, which is in the range of vibration frequencies of electric vehicle during its normal operation. The purpose is to maximize the minimum natural frequency observed in each of the case.
How to determine the protective effect of a battery box?
6.4. Impact protection strategy In order to evaluate the protective effect of the bottom structure of the battery box, the protective effect (PE) can be calculated by comparing the reduction of the maximum axial compression of the battery under the protective structure with the ratio under the condition of a homogeneous plate.
Does vehicle finite element model impact simulation have similar trends?
Vehicle finite element model impact simulation From the curve trend in Fig. 3, it can be observed that the two curves have similar trends. The time when the first peak appears is about 10 ms, and there is not much difference between the acceleration measured in the experiment and the acceleration calculated in the simulation.
