The battery pack according to the present disclosure is a battery pack mounted under a floor of a vehicle. The battery pack comprises a lower case fixed under the floor and on which a battery stack is placed, an upper case attached to the lower case, and a support member extending upwardly from a rigid body provided inside the lower case to support a back surface of the upper case. The battery pack may further comprise an elastic member disposed on a surface of the upper case and sandwiched between the upper case and a lower surface of the floor. In such a configuration, it is possible to suppress the upper case of the battery pack from vibrating.

This disclosure details mounting systems and associated methods for mounting a battery pack to an electrified vehicle. An exemplary electrified vehicle may include a frame, a battery pack, and a mounting system for mounting the battery pack to the frame. The mounting system may include one or more side rails. Each side rail may include a predefined crush initiator configured to plastically deform for absorbing and transferring energy during vehicle impact loading events.

A vehicle lower portion structure includes a pair of rocker panels and an electric power supply device. The rocker panel is configured to include an outer portion, an inner portion, and a first shock absorbing portion. The outer portion is positioned on an outer side in a vehicle width direction. The inner portion is formed integrally with the outer portion, is positioned inward of the outer portion in the vehicle width direction, and forms a closed sectional portion with the outer portion. The first shock absorbing portion extends in the vehicle width direction from the outer portion to the inner portion in the closed sectional portion and is disposed to overlap the electric power supply device in vehicle side view.

An apparatus for storing electric energy for a motor vehicle includes a plurality of energy storage modules and a main body which can be fastened to the motor vehicle. Each energy storage module includes energy storage for storing the electric energy and a carrier, in which the energy storage is arranged. The carrier is fastened in an individually detachable manner to the main body in the state in which it is fastened to the motor vehicle, with the result that a first one of the energy storage modules can be removed from the apparatus without it being necessary for the carrier of a second one of the energy storage modules to be detached from the main body.

An electric or hybrid sport car comprising a battery pack incorporating at least one structural element of the vehicle frame, and wherein said structural element can be removed from the vehicle frame only together with the battery pack.

A side vehicle body reinforcing structure may include a center floor panel; a side sill respectively combined to both sides of the center floor panel in a width direction of the vehicle body; a seat cross member configured so that a lower end thereof is combined to the center floor panel and both ends thereof in a width direction of the vehicle body are combined to the side sill to cross the center floor panel in a width direction of the vehicle body; a battery case combined to a lower surface of the center floor panel and disposed at an internal to the side sill; and a partition wall panel respectively both side plates of the battery case in a width direction of the vehicle body, wherein a combining bolt sequentially penetrating the seat cross member and the center floor panel is engaged to the partition wall panel.

A method and system for swapping batteries in an electric vehicle is disclosed. The method includes dismounting a first battery assembly, moving to a second battery assembly and mounting the second battery assembly onto the vehicle. Mounting and dismounting are accomplished by an onboard mounting and dismounting system. The method can be used in a zero infrastructure environment such as an underground mine since mounting and dismounting are accomplished by components on the vehicle itself. An auxiliary battery pack powers the vehicle during between dismounting a battery pack and mounting another battery pack.

A motor vehicle that includes a body having a support structure, a high-voltage battery having a battery housing and at least one battery module arranged in the battery housing. The battery housing is arranged on and attached to the support structure to serve as a main floor panel. A battery cover is detachably arranged on the underside of the battery housing to serve as underride protection and facilitate access to the at least one battery module.

Provided are a circumferential locking mechanism, a battery securing device comprising same, a traction battery, and a vehicle. The circumferential locking mechanism comprises: a first component comprising an inner ring gear (10), the inner ring gear (10) having inner straight teeth (11) distributed along an inner circumference; a second component comprising an outer ring gear (20) and a tightening sleeve (30), the outer ring gear (20) having outer straight teeth (21) distributed along an outer circumference, the tightening sleeve (30) being fixed inside the outer ring gear (20) in an embedded manner, wherein the inner straight teeth (11) are adapted to engage with the outer straight teeth (21).

A connector and a decking structure between a vehicle body and a battery including the same are provided. The connector includes a first connector assembly that has a downwardly protruding guide pin and a second connector assembly that is coupled to the first connector assembly in a lower portion of the first connector assembly and includes a guide aperture in which the guide pin is accommodated.
