FIELD OF INVENTION

[0001] Embodiments of the present disclosure relate to a protective casing for batteries, and more particularly to a protective casing for a battery pack of an electric vehicle.

BACKGROUND

[0002] The battery pack is the most important component of an electric vehicle as the battery pack accommodates energy-storing battery cells. Electric vehicles use the energy stored in the battery cells of a battery pack to operate. Hence, it is vital to provide additional protection to the battery pack.

[0003] Conventionally, electric vehicles typically store battery packs within a deck surrounded by a frame of the electric vehicle. Electric vehicle frames protect the battery pack during vehicle operation and various events such as accidents, battery swapping, battery transportation, etc. In this case, the frame of the electric vehicle is damaged, which leads to damage to the battery pack, causing adverse effects. A damaged battery pack can eventually damage the internal battery cells, causing a fire and explosion.

[0004] In one conventional system, a battery module, which is resistant to shock and vibration with robustness is disclosed. This battery module comprises a vibration-shock absorbing part for absorbing vibrations and shocks in elastic contact with end faces of unit batteries, held in insertion-fitted in a battery retainer part of a battery retainer frame.

[0005] In another conventional system, a battery housing device having a plus terminal and a minus terminal, a plus pole spring is disclosed. The battery housing device is resistant to vibration and shock in order to prevent performance degradation of the battery.

[0006] US5393617A provides a bipolar electrochemical battery of stacked wafer cells, wherein the stack of cells is held in compression by means of a layer of sponge rubber between one or both of the metal foil contacts and the end plates, and respectively, of the outer housing. Alternatively, a spring or a gas-filled compressible pad is used instead of the sponge rubber. However, the inclusion of such an additional complaint part in the finished battery assembly is detrimental to the cost, volume, and weight of the resulting battery assembly.

[0007] US5547777A provides a fuel cell having uniform compressive stress distribution overactive area, which uses endplates, ties rods, and compliant pads. Although the mechanical approach for managing the forces on a cell stack is effective, however at the same time, this mechanical approach provides a heavy and bulky solution, which is not cost-effective for mass manufacturing.

[0008] Further, many electric vehicles use the battery swapping technique to recharge the battery pack before usage. The constant manual rough swapping of the battery pack also leads to damage to the battery pack. Damage to the surface of the battery pack ultimately affects the interior battery cells. The battery pack structural casing needs to be improved to minimize such mentioned damage effects.

[0009] Hence, there is a need for an improved protective casing for a battery pack of an electric vehicle, which is lightweight, cost-effective, and therefore addresses the aforementioned issues. Further, there is also a need for a protective casing with ergonomic designs that facilitates extra safety for the electric vehicle’s battery pack.

SUMMARY

[0010] This summary is provided to introduce a selection of concepts, in a simple manner, which is further described in the detailed description of the disclosure. This summary is neither intended to identify key or essential inventive concepts of the subject matter nor to determine the scope of the disclosure.

[0014] The shock absorption casing is disposed of around the housing. The shock absorption casing is configured to safeguard the housing and the battery pack by absorbing the shocks and vibration during detrimental actions. The shock absorption casing is affixed to the outer surface of the housing in a way that, shock absorption casing safeguards the edges of the housing and the surface of the housing expose to the ambient air to dissipate the heat from the battery pack.

[0015] The shock absorption casing is made of a material selected from the group comprised of damping materials including an ethylene propylene diene monomer (EPDM) rubber to safeguard the battery pack from external impacts, shocks, and vibration. Further, the shock absorption casing is equipped with a plurality of protrusions. The plurality of protrusions disposed on the outer surface of the shock absorption casing thereby reducing the thickness of the shock absorption casing.
