DETAILED DESCRIPTION
[0009] Embodiments of the present invention relate to heated rechargeable electric battery enclosures, particularly for rechargeable electric batteries used to power artillery equipment, and especially howitzers. In preferred embodiments, the batteries are formed of lithium ion battery cells. In other embodiments, the batteries cells may be Pb-acid, Ni- metal hydride, Ni-Zn, and other rechargeable as well as primary or non-rechargeable battery cells.
[0010] Fig. 1 schematically shows a cross-sectional view of a rechargeable electric battery 10 according to an embodiment of the present invention. Battery 10 includes an outer enclosure 12 surrounding a plurality of planar battery cells 14 that are arranged in a stack, four of which are shown in this exemplary embodiment. In other embodiments, the number of cells 14 may be less than or greater than four. Planar battery cells 14 are each separated from one another by a plurality of internal channels 16 in battery 10 in between cells 14. Channels 16 are preferably at least partially filled with porous compressible interconnectors 18, which act to provide an electrically-conducting interconnection between adjacent cells 14. Cells 14 each include a positive and a negative electrode, with the positive electrodes connecting to a positive output terminal 20 (Fig. 2) and the negative electrodes connecting to a negative output terminal 22 (Fig. 2). Positive electrodes of cells 14 may be connected to positive output terminal 20 by a positive current collector 24 and negative electrodes of cells 14 may be connected to negative output terminal 22 by a negative current collector 24. Current collectors 24, 26 may be positioned at ends of the stack of cells 14, extending parallel to cells 14.
Interconnectors 18 may also be provided at the ends of the stack of cells 14, such that one interconnector 18 is provided between positive current collector 24 and a first end cell 14 to form a channel 16 between the first end cell 14 and positive current collector 24 at the first end of the stack, and another interconnector 18 is provided between negative current collector 26 and a second end cell 14 to form a channel 16 between the second end cell 14 and negative current collector 26 at the second end of the stack.
[0011] In order to effectively heat cells 14 in colder environments and to allow cells 14 to reach an optimal temperature quickly after startup, two planar heaters 28 are provided at the planar peripheries of cells 14 and at the peripheries of the interconnectors 18 between cells 14. Heaters 28 are adjacent to opposite peripheries of all of cells 14 such that cells 14 extend parallel to each other from one heater 28 to the other heater 28. In an alternative embodiment, each heater 28 may be replaced by two or more heaters in a planar arrangement at the planar peripheries of cells 14 and at the peripheries of the interconnectors 18 between cells 14.
[0012] Compressible interconnectors 18 may be made any material that has sufficient properties such as, for example a wire mesh, metal or carbon fibers retained in a compressible elastomeric matrix, or an interwoven conducting mat, consistent with the requirement for a compressible flexible electrically-conducting interconnection between adjacent cell plate module surfaces. In preferred embodiments, interconnectors 18 may be porous, corrugated and highly conductive.
[0013J In preferred embodiments, battery 10 contains nanoscale particles which fundamentally allow for high charging rates. The nanoscale particles may be coated with a thin layer of carbon. For example, anodes of cells 14 may be formed of lithium titanium oxide (LTO) nanoparticles and cathodes of cells 14 may be formed of lithium iron phosphate (LFP) nanoparticles.
(0014] Fig. 2 schematically shows another cross-sectional view of a rechargeable electric battery 10 along A-A in Fig. 1. As discussed above, positive electrodes of cells 14 may be connected to positive output terminal 20 by positive current collector 24 and negative electrodes of cells 14 may be connected to negative output terminal 22 by negative current collector 24. A battery management system 30 may be provided between current collectors 24, 26 and respective output terminals 20, 22 to control the supply of current output by battery 10. Battery management system 30 may also control the operation of heaters 28, either automatically in response to the surrounding temperature or in response to inputs by an operator.
[0015] Fig. 3 schematically shows a perspective view of battery 10, with terminals 20, 22, current collectors 24, 26 and interconnectors 18 being omitted for clarity. The dimensions of battery 10 are defined by outer enclosure 12, which is shown having a length L, a width W and a height H. Cells 14 extend parallel to each other in directions of length L and width W and are stacked on top of each other along the direct of height H, with interconnectors 18 in between. Heaters 28, one of which is visible in Fig. 3, are positioned at the peripheries of cells 14 and extend parallel to each other in directions of length L and height H, such that heaters 28 are both positioned perpendicular to cells 14 and both transfer heat to cells 14 at the outer width peripheries of cells 14. Battery management system 30 is located adjacent to cells 14 in the direction of length L.
[0016] In one preferred embodiment, battery 10 is dimensioned such that length L is 9.875 inches, width W is 5.8 inches and height H is 5.4 inches.
[0017] In the preceding specification, the invention has been described with reference to specific exemplary embodiments and examples thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative manner rather than a restrictive sense.
