The main conclusions can be summarized as follows. Except for impact energy, the dynamic responses and internal failure modes of LIBs mainly depend upon the impactor types and SOCs. The peak force of the battery under flat-end cylinder head impacting is larger than that under hemispherical one, but the failure displacement is smaller.
When the battery is loaded under ball impactor in the X direction, its main failure behavior is the facture of jellyrolls. Under impact in the Z direction, the shear fracture of jellyroll is beneficial to the batteries from further internal short circuits.
When the battery under ball impactor in the Z direction, its main failure behavior is the fracture of jellyrolls. Furthermore, the homogenous models of LPB are developed to make the crash simulation of full EV feasible.
The batteries tested are one of the most common daily energy storage units of EV. The specific aim of this paper is to construct the homogenous model of battery to make the crash simulation of full EV feasible. Thus, the shape of impactors should be selected according to the impact scenarios of EV.
Although the cylindrical impactor has a larger contact area and therefore a greater increase in force at first, the support for the cells is open in the middle so that the cylinder can move into the cells. This makes it possible for the cells to move out of the way.
The hemispherical impactor is forced into the cell by means of a compression test rig. The impactor itself is wrapped with Kapton and insulating tape to prevent the impactor from short-circuiting the cell. The displacement of the impactor is measured by a linear potentiometer.
