What happens if you punch a hole in a battery module?

Crack propagation in the armor plate goes through circumferentially around the punch tip, leaving a cap on the punch tip and a hole in the armor plate. Further indentation of the punching object enlarges the diameter of the punctured hole and deforms the plastic enclosure of the battery module.

How does a battery cell deformation differ from a punch tip?

Shortening of the battery cells above the punch tip vs. the indentation distance of the punch is shown in Fig. 17, in which three different stages of the battery cell deformation can be more clearly distinguished. At the first stage, the battery is shortened slightly.

What causes a battery cell to puncture a floor panel?

The gradually concentrated indentation from the punch tip and the resistance from the floor panel cause compression and shortening of the cells exactly above the punching tip. It can also be noticed from the last frame in Fig. 16, that the upward moved battery cell finally punctured the floor panel.

Can a ground impact damage a battery pack?

The “Floor” battery pack configuration is found, amongst others in the BMW i3, Nissan Leafs, Mitsubishi i-Miev, Tesla Model S, SmartBatt prototype vehicle and many smaller experimental cars. To the best of authors' knowledge, no work has been reported in the open literature on predicting damage to the battery pack due to the ground impact.

What happens if a battery pack fractures in the armor plate?

However in the present problem after fracture occurs in the armor plate, other components in the battery pack are inevitably involved into the penetration process and their influence on the global and local response cannot be neglected, which will be shown in Section 7. 7. Results of global numerical simulation of the battery pack 7.1.

How does energy affect shortening of a battery cell?

However, from the point of view of energy, as shown in Fig. 27 b, shortening of the central battery cell in the dynamic case becomes smaller than that in the quasi-static case when dissipation of the reaction force work exceeds a relative low value, saying 1 kJ. This can be explained with the deformation profile comparison in Fig. 28.
