Abstract

A crash elements structure in an electric vehicle for reducing the damage to a vehicle battery caused by a vehicle collision. The crash elements structure may be situated near a corner of the vehicle battery, and may channel energy received by the vehicle away from the vehicle battery. The crash elements structure includes an upper structure positioned above and laterally offset from a lower structure, and a “W” structure that interfaces between the vehicle battery and the upper and lower structures. The upper and lower structures include several shells coupled together to form hexagonal apertures. The specific arrangement of the shells and the upper and lower structures influences the transfer of energy through the crash elements structure in the event of a collision.

Dependent claims

An electric vehicle comprising:

a vehicle battery for powering the electric vehicle, the vehicle battery including a battery top surface and a battery side surface, the battery top surface and the battery side surface forming an angle along a battery corner of the vehicle battery;
a crash elements structure comprising:
an upper structure coupled vertically above the battery top surface;
a lower structure coupled laterally to the side of the battery side surface and vertically below the upper structure;
and
a “W” structure including:
a first side being substantially vertical and coupled laterally to the side of the upper structure;
a second side being substantially horizontal and coupled vertically below the upper structure and vertically above the battery top surface;
a third side being substantially vertical and coupled laterally to the side of the battery side surface and laterally to the side of the lower structure;
and
a fourth side being substantially horizontal and coupled vertically below the lower structure.
