The present disclosure generally relates to apparatuses and wearable armor systems including electrical sources, and more specifically, to a conformal battery-integrated armor system.
A significant number of military assets, including multiple types of soldier-worn systems, rely heavily on power provided by rechargeable batteries. As the capabilities of these systems increase, there is an ever-increasing need for batteries with more electrical energy/power. Along with the increasing need for additional electrical capacity to support these growing energy demands comes added weight and mounting space limits due to additional batteries being added to a soldier's already heavy carrying load. Additionally, batteries can be bulky, cumbersome, and restrict body movement for the dismounted soldier.
Conformal batteries (e.g. Conformal Wearable Battery, CWB) seeking to address the space limitations and operator ergonomics have been developed due to the increased need in electrical capacity. However, current conformal batteries offer reduced ballistics protection when combined with soft armor Kevlar® (E.I. du Pont de Nemours and Company, Midland, Mich.) packaging that has limited stopping protection. An alternative approach is to use Small Arms Protective Insert (SAPI) plates with the conformal batteries because of the greater ballistics protection, but such levels of ballistic protection may not be required in every situation, with the SAPI plates only adding to the carrying weight concern.
Accordingly, there is a need for improved apparatuses and wearable armor systems including electrical sources.

In various embodiments, the bottom shell 108 and top shell 110 may be secured together by a friction fit, a removable adhesive, or an external fabric or tape wrap, but any securement means can be used without departing from the scope of this disclosure.
It is noted that the housing case 102 and/or various components thereof may be made from a variety of materials. For example, in one non-limiting embodiment, the housing case 102 is made from a fiber-reinforced composite, such as an aramid fiber (Kevlar® (E.I. du Pont de Nemours and Company, Midland, Mich.)) reinforced composite. In a further non-limiting embodiments, the housing case 102 is made from a rigid plastic such as acrylonitrile butadiene styrene (ABS) or nylon, polycarbonate, UHMWPE. It should be noted that both the bottom shell 108 and the top shell 110 have a curved profile CP1, which allows the housing case 102 to conform to the chest area of a human user. However, it should be appreciated that housing case 102 can also have a flat profile. In some embodiments, the housing case 102 is a rigid or conformal case which may be environmentally sealed against dust and water intrusion (e.g. IP67 or IP68 in accordance with the International Electrotechnical Commission standards). Additionally, the housing case 102 may be rated for MIL-STD-810 shock, vibration, and drop testing in accordance with the Institute of Environmental Sciences and Technology standards of the United States Military. The armor system 100 may be designed to provide additional ballistic protection when worn in front of or behind the interior ballistic panel 116, or may act as standalone ballistic protection (e.g. NIJ Level IIA, II, III, or IV in accordance with the National Institute of Justice standards) when worn without the interior ballistic panel 116.
In some embodiments, the housing case 102 may be made from a thin, impact/ballistic resistant case material which may be a thermoplastic or thermoset resin case, with or without fiber reinforcement. A lightweight, thermally insulated, fire-resistant layer may be arranged between the interior ballistic panel 116 and the bottom shell 108 to protect a user in the event of battery thermal runaway or a fire. Example fire-resistant layers include those formed from dry fibers of Kevlar® (E.I. du Pont de Nemours and Company, Midland, Mich.), and/or carbon fibers, ceramic materials or foam.
In some embodiments, the polymer materials used to make the housing case 102 can be a fiber reinforced thermoplastic or thermoset composite. Non-limiting examples of thermoplastic resin used to make the bottom shell 108 and the top shell 110 are polypropylene, polyethylene, polyether ether ketone, polyphenylene oxide, polyphenylene ether, Noryl, and polyvinylidenefluoride. Non-limiting examples of thermosetting resin used to make the bottom shell 108 and the top shell 110 are epoxy, vinyl ester, polyester, polyurethane. Non-limiting examples of fiber reinforcement materials in the composite include carbon, glass, aramid, polypropylene, polyethylene, and hybrid laminates made with multiple reinforcement materials. The fiber reinforcement used to make the composite may include various material forms, including but not limited to random mats, scrims, chopped fibers, knits, unidirectional plies, three-dimensional weaves, three-dimensional fiber preforms, plain weave fabrics, twill fabrics, harness satin fabrics, prepreg (i.e. pre-impregnated composite fibers where a thermoset polymer matrix material, such as epoxy, or a thermoplastic resin is already present), Tpreg (i.e. thermoplastic prepreg), or combinations thereof. In some embodiments, the polymer materials used to make the housing case 102 can be a fiber reinforced thermoplastic or thermoset elastomer composite. Non-limiting example of thermoplastic or thermosetting resin used to make elastomer composite for the housing case 102 are rubber, polyurea, or polyurethane.
