Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Battery boosters have also been around for many years and are generally utilized to provide power to a vehicle battery for starting the vehicle in cases where the vehicle battery is substantially drained. Conventional battery boosters generally lose a charge over time, thus forcing the user to continually purchase new battery boosters, which can be expensive. In addition, conventional battery boosters are generally large, bulky, and heavy. Because of the inherent problems with the related art, there is a need for a new and improved portable battery booster for efficiently providing a compact, light, and energy efficient reserve activated battery to jump start a vehicle.
A system for efficiently providing a compact, light, and energy efficient battery to jump start a vehicle. The invention generally relates to a reserve battery which includes a housing, a battery means adapted to be received by the housing, a pair of cable means, each of the cable means having a proximal end and a distal end, the proximal end electrically connected to the battery means and the distal end detachably connected to a discharged battery of the vehicle. The battery is generally comprised of one or more batteries having the type of primary lithium-metal, rechargeable lithium-ion, and/or lithium-polymer and more specifically preferably comprised of lithium iron phosphate for fast charging, small size, and high performance. The battery may also be connected to one or more supercapacitors, an internal CPU, DC/DC converter, etc. to increase performance. The cable means includes jaws that detachably connect to the housing in a flush and sleek manner.
There has thus been outlined, rather broadly, some of the features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction or to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
The housing 20 also generally includes slots 24 along a rear end of opposing sides 23 for receiving the proximal end 31 of the cables 33 (positive and negative cables) and a retaining element 25 spaced laterally from the sides 23 of the forward end of the housing 20 for receiving the jaws 36c, 38c of the clamps 34. The housing 20 may further include a recharge port 27 for charging the battery pack 40, the port 27 being electrically connected to the cells 41 of the battery pack 40. The housing 20 may further employ a pivotal handle 28 for carrying, wherein the handle 28 is received within a slot 29 of the housing 20. The handle 28 may also serve as a stand or support.
The cable means 30 generally includes the cables 31 electrically connected to the battery pack 40 for transferring power and a clamp 33 connected to each cable 33 forming the distal end 32. Generally, a pair of clamps 33 are utilized, one for positive and one for negative (ground). The clamp 34 includes a first section 35 and a second section 37, the first section 35 pivotally connected to the second section 37 near a longitudinal and lateral center pivot point 39 of the clamp 34, each section 35, 37 having an integral jaw 36c, 38c and handle 36a, 38a being comprised of a plastic injection molded structure, and each jaw 36c, 38c having copper clamping teeth 36d, 38d electrically connected to the cable 33 and battery pack 40. The handles 36a, 38a may include gripping means, such as gnp indentations 36b, 38b, for more easily maneuvering and operating the clamp 34. The exterior contour of the clamps 34 also generally includes rounded ends to follow the shape of the housing 20. The upper surface of the clamp 34 along the upper section 35 and the lower surface of the clamp 34 along the lower section 37 are generally flat and when the clamp 34 is detachably connected to the retainer element 25 of the housing 20, the upper surface and the lower surface of the clamp 34 is flush and parallel with the upper surface and the lower surface of the housing 20 as illustrated in
The power supply of the present invention is generally comprised of a battery pack 40 having a plurality of battery cells 41 electrically connected for transferring power to the cables 33 to provide power to the discharged battery of the vehicle. The battery pack 40 is generally detachably connected to the housing 20 within an inner chamber 26. The battery pack 40 may be completely contained within the housing 20 or the inner chamber 26 be comprised of an indentation in the housing 20 and thus the battery pack 40 having exterior walls that integrally follow the exterior shape of the housing 20 and form an exterior surface (i.e. be flush with the exterior of the housing 20). Alternately, a plurality of battery cells 41 may be separately inserted and contained within the housing 20.
The battery cells 41 are generally small in size, thus allowing for the housing 20 to be small in size. Generally, each of the battery cells 41 employs a 26 mm×65 mm size, thus being substantially small so that the housing 20 may maintain a slim profile. The battery cells 41 are generally comprised of a primary lithium-metal type, a rechargeable lithium-ion type, and/or a lithium-polymer type. A preferably type of the battery cell 41 is a lithium iron phosphate (LiFeP04) type thus allowing for fast charging, small in size, and having high performance. In one embodiment, four cells 41 meet the specifications of a DOW-KOKAM cell being SLPB 9543140H5. Other embodiment includes an OMNICEL ER 18505HD lithium thionyl chloride cell and cells manufactured by A123 SYSTEMS, such as A123 ANR26650M1A. In further alternate embodiments, the cells 41 may include rechargeable battery cells combined with primary (non rechargeable) battery cells to enhance the overall performance of the batteries. Alternately, or additionally, the present invention may employ a hybrid system wherein the battery cells 41 may be combined with one or more supercapacitors 60 to store energy and provide quick jolts of power to the discharged battery. Alternately, a reserve battery cell(s) 41 may be utilized, such as a reserve battery that requires manual activation prior to use.
Additionally, the present invention generally employs a heat sink that uses minimal space and is light weight to maintain battery surface temperature that does not exceed 50 degrees Celsius during operation. Additionally, a wiring harness to individually connect each of the battery cells 41 is utilized. Further, an electronic circuit board that uses minimal space and is light weight is used to protect the battery cells 41 by providing features such as detecting a shorted load, preventing electric current from flowing through the terminals and into the lithium ion battery stack, detecting a low lithium ion battery voltage and not allowing discharge and related safety and performance features.
