New Energy Bottom Battery Cabinet Damaged

Does bottom impact damage the battery system?

Therefore, under bottom impact forces, internal damage to the battery system occurred [11, 12, 13], as shown in Fig. 1. Fig. 1. Schematic diagram of the power battery system structure for new energy vehicles

What causes battery failure in New energy vehicles?

This study investigated the failure characteristics of the battery system caused by bottom collision of new energy vehicles, analyzes the complex scenario conditions during the bottom impact process, and proposes a new energy vehicle bottom impact simulation method through the connection of data and mechanism models.

Do battery pack bottom plates resist foreign object impacts?

In this study, it was observed that battery pack bottom plates of different materials exhibited varying capacities, resisting foreign object impacts. Results indicated that an impact energy of 150 J was equivalent to a 10 kg foreign object colliding with the bottom of the battery pack at a speed of ~20 km/h.

What happens if a battery is hit by a foreign object?

Results indicated that an impact energy of 150 J was equivalent to a 10 kg foreign object colliding with the bottom of the battery pack at a speed of ~20 km/h. Furthermore, as the impact energy increased, battery cells were prone to compression damage.
