6 FAQs about [New energy battery collision deformation]

Does a battery pack undergo significant deformation under ball impact?

By analyzing the simulation results, the deformation, stress, and strain distribution at the bottom of the battery pack under ball impact were obtained, as well as the related variation patterns. It was observed that the battery pack underwent significant deformation under impact load, and stress concentration also occurred in certain areas.

Do prismatic Lithium-ion batteries fail under dynamic impact?

Battery modules of new energy vehicles are frequently exposed to dynamic impacts during traffic accidents. However, current research on the mechanical safety of prismatic lithium-ion batteries (PLIBs) primarily focuses on quasi-static states, and the failure mechanism of batteries under dynamic impact remains incompletely understood.

What happens if a battery pack is impacted by a collision?

During the period of 40 ms-60 ms, the maximum stress values of all lifting ears exceeded a certain limit and significant plastic deformation occurred. This means that in the case of bottom collision impact, the lifting ears of the battery pack will experience huge stress, and there is a high possibility of fracture failure.

What happens if a battery fails under dynamic loading conditions?

The load corresponding to these points is the destructive force of the PLIB, and it can be seen that the destructive force when the battery fails under dynamic loading conditions is lower than that under low-velocity conditions, which is consistent with the results of the 18650 batteries in reference [ 35 ].

What is the dynamic response of a battery under three-point bending conditions?

Dynamic response of the battery under three-point bending conditions. Compared with the battery failure under quasi-static experiments, the peak load increases rapidly with the increase of the speed and the corresponding inertia factor and strain rate.

Do dynamic battery shocks deform?

Experiments on dynamic battery shocks are accompanied by violent deformation and heating, and it is difficult to observe the deformation pattern of PLIBs in experiments.
