89 1. TUNABLE FRANGIBLE BATTERY PACK SYSTEM BACKGROUND OF THE INVENTION 1. Field of the Invention The Subject invention generally relates to battery packs, and more particularly relates to a tunable frangible battery pack system for use in a vehicle or other industrial equipment. 2. Description of Related Art Battery packs have been used for numerous years in elec tric vehicles, such as automobiles, boats, aerospace vehicles, and within other industrial equipment applications. Many of the electrical systems used in these prior art vehicles and equipment are designed to minimize the possibility of short circuiting and to reduce the potential of Voltage exposure to emergency responders and other people in the general public. Such precautions help to reduce the possibility of an electro cution or other injury due to high Voltage encounters and situations. There have been many different attempts at pro viding an electric system that will disconnect electrical cir cuits due to a crash of a vehicle or high temperature situations in a vehicle or industrial equipment application. Many of these prior art systems will disconnect the battery from the circuits thus creating an open circuit and protecting any responders and other people from dangerous high Voltage situations. Generally, these prior art disconnect systems for battery packs will disconnect when a predetermined force is applied to the vehicle or equipment or if a predetermined thermal event occurs within the circuitry of the battery and/or electrical system. One of the prior art methodologies for disconnecting bat tery cells uses a conductor wire that is either welded or bonded to a battery cell and is capable of being broken when a mechanical force is applied thereto. However, one problem with these prior art systems is that the mechanical strength of the breakable conductors was excessive and did not allow for the conductor to break unless the most extreme forces or situations acted on the vehicle or industrial equipment. There fore, the disconnecting of the power Supply system from the electrical vehicle or equipment did not occur during all emer gency situations as many designs originally called for. Fur thermore, the prior art methodologies of wire bonding the conductors to the cells did not provide a consistent fusing current mechanism Such that high thermal events would not break the conductor, thus leaving the equipment connected to circuits which may lead to electrocution and other injuries to users or responders to an accident scene. Other types of connecting wire conductors between battery cells and other equipment have been used, including various bonding tech niques for Smaller diameter wires, conductive epoxies for connection between a battery cell and a bus bar or collector plate, Soldering techniques that include solders made of nickel, tin, copper, plated metals, low metal alloys, etc. Fur thermore, other prior art methodologies have tried installation displacement connectors to connect the battery cell to a bus bar or collector plate, mechanical crimping or pressure crimp ing has also been used to connect battery cells to a bus bar. Furthermore, it should be noted that conductor materials used for prior art wire conductors include copper, gold, nickel, solder, indium, tin, aluminum, low melt alloys and the like. However, there have been problems with the prior art dis connect systems and methodologies for an electrical system having a battery pack or like power Source. Some of the problems of the prior art include having the conductors arranged between battery cells and a bus bar or the like connected via bonding techniques that give the conductors US 7,923,144 B very high mechanical strengths that do not allow the conduc tor to break unless the most extreme situations occur Such as very high forces or extremely high heat. Furthermore, many of these prior art methodologies for creating a disconnect system use high cost materials and high cost processes to create Such systems thus increasing the manufacturing costs and overall price structure for the manufacturer. Therefore, there is a need in the art for an improved fran gible battery pack system for use in an electric Vehicle or industrial equipment. Furthermore, there is a need in the art for a tunable frangible battery pack conductor that is capable of being made in various widths and connected via an ultra Sonic wedge bonding process to allow for breaking and dis connecting of the battery pack from the electrical vehicle or industrial equipment at a predetermined force or predeter mined thermal parameters. There also is a need in the art for a low cost and easy to manufacture methodology and appa ratus for creating a tunable frangible battery pack system including aluminum conductor wires. SUMMARY OF THE INVENTION One object of the present invention may be to provide an improved frangible battery pack system. Another object of the present invention may be to provide a tunable frangible battery pack system for use in a vehicle or industrial equipment. Still another object of the present invention may be to provide a tunable frangible battery pack conductor wire made of aluminum with predetermined amounts of magnesium and nickel added thereto. Still another object of the present invention may be to provide a frangible battery pack conductor shaped in the form of a round wire or in the form of a ribbon. Still another object of the present invention may be to provide a frangible battery pack conductor that is a low cost element that has high thermal conductivity and low electrical resistivity. Still another object of the present invention may be to provide a frangible battery pack conductor that has a small cross section but is strong enough to support itself under normal operation conditions while not adding significant strength to the battery pack system. Still another object of the present invention may be to provide a frangible battery pack conductor that has a tunable diameter, length and wire path that is capable of being designed to fatigue and fracture at predetermined vibration levels and thermal levels which may exceed acceptable bat tery pack limits. To achieve the foregoing objects a frangible battery pack system for use in an electric vehicle or with industrial equip ment is disclosed. The frangible battery pack system includes a housing and a plurality of battery cells arranged within the housing. The frangible battery pack system also includes a collector plate arranged on each end of the housing and a conductor arranged between the collector plate and the bat tery cell. One advantage of the present invention may be that it provides a novel and improved frangible battery pack system for use in an electric vehicle or on other industrial equipment. Still a further advantage of the present invention may be that it allows for the use of a tunable frangible battery pack system having a conductor arranged between a collector plate and a battery cell. Still another advantage of the present invention may be that it provides away of creating a tunable frangible battery pack system wherein a conductor is capable of being designed with
90 3 different diameters, lengths, and paths between the battery cells and a collector plate such that a predetermined fatigue and fracture will occur at predetermined force or thermal levels that exceed the acceptable battery pack limits in the vehicle or equipment environment. Still another advantage of the present invention is that it may minimize the possibility of short circuiting in the elec trical system of a vehicle thus reducing the potential Voltage exposure for emergency responders or the like during acci dents of electrical vehicles or industrial equipment. Still another advantage of the present invention is that the conductor for the battery pack system may be mechanically or electrically tuned to fail before a circuit reaches a prede termined threshold. Still another advantage of the present invention is that the battery pack can be applied to various technologies such as aerospace, aviation, marine sectors, automotive sectors and industrial equipment. Still a further advantage of the present invention may be the use of frangible conductors made from aluminum that are ultrasonically bonded to the battery cells and a collector plate. Still another advantage of the present invention may be the use of frangible conductors that are designed to provide cur rent carrying capability and mechanical strength during nor mal operation but are capable of breaking thus disconnecting the power source from the electrical circuit and the power Source from responders to vehicle crashes or industrial equip ment accidents. Other objects, features and advantages of the present invention will become apparent from the Subsequent descrip tion and the appended claims, taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a top view of a battery pack system according to the present invention. FIG. 2 shows a top view of one battery cell connected to a collector plate via a conductor according to the present inven tion. FIG.3 shows apartial cross sectional view of a battery pack system according to the present invention. FIG. 4 shows a top view of a battery cell according to the present invention. DESCRIPTION OF THE EMBODIMENT(S) Referring to the drawings, a battery pack system 10 for use in an electric Vehicle or in other industrial equipment is shown. It should be noted that the battery pack system 10 shown in the drawings is for use in an electric Vehicle, how ever the battery pack system and battery cells may be used in any combination and in any design known for use in any number of industries including but not limited to any type of vehicle and any technology dealing with aerospace, marine, aviation, industrial equipment, and any other electrical sys tem that has a need for protecting emergency responders or everyday users from electrocution and other injuries due to high Voltage applications. The battery pack system 10 has a tunable frangible con ductor/wire 12 arranged between a plurality of battery cells 14 and a collector plate 16. The use of the frangible battery pack conductor 12 will minimize the possibility of short circuiting and reduce potential exposure to high Voltages by emergency responders or others in contact with the electric vehicles and industrial equipment. The battery pack system 10 of the present invention may include connections involv US 7,923,144 B ing the battery cells 14 that will break at a predetermined impact and a predetermined thermal event. In one embodi ment of the present invention the collector plate 16 will be connected to a plurality of battery cells 14 by the use of a narrow and thin conductor 12 Such as a wire bond connection. It should be noted that the present invention may be designed such that the frangible conductor 12 is used within the battery pack system 10 to disconnect all of the battery cells 14 from some or all portions of the electrical circuits of the electric vehicle or to disconnect predetermined portions of the cir cuits from the battery cells 14. Furthermore, the wire conduc tor 12 may be mechanically and electrically tuned to prede termined specifications to fail before the circuit reaches a predetermined threshold of extremely high heat or extreme forces applied thereto such that the battery pack system 10 may be accessible to emergency responders or other users of the electric vehicle without the threat of electrocution or injury. It should be noted that the system 10 generally is designed for use in an electric Vehicle having a high Voltage electric system. It should be noted that any of these vehicles may be any of the known auto vehicles Such as passenger's vehicles, military vehicles, delivery vehicles and the like. Furthermore, the same technology has also been designed for use on aerospace, aviation, and marine sector vehicles and also industrial equipment that have any type of electric sys tem and power Supply. This technology may also be used in any other technologies such as but not limited to mining equipment, cranes, presses or the like. Therefore, the present invention of a frangible battery pack system 10 can be used with any known electric vehicle or electrical system indus trial, personal or otherwise. FIGS. 1 through 4 show a tunable frangible battery pack system 10 according to the present invention. The battery pack system 10 includes a housing 18. The housing 18 is generally a two piece clamshell housing that has a plurality of orifices 20 therethrough. The orifices 20 are generally circular in shape, however any other shaped orifice may be used. The housing 18 has a plurality of counter bores 22 arranged on each piece thereof. Each of the counter bores 22 will be used to hold and arrange therein a battery cell 14. The orifices 20 are arranged at or near a centerpoint of the counterbore 22 of the housing 18. It should also be noted that it is contemplated to have a cooling tube arranged through the housing 18 to allow for cooling of the batteries 14 if need be. It should be noted that in one contemplated embodiment the housing 18 is made of a plastic material that is injected molded into the predetermined shape for the housing 18. However, it should be noted that any other type of material including metal, ceramic, composite, or natural material may be used for the housing 18 depending on the design requirements and envi ronment in which the battery pack system 10 will be used. Arranged within each counter bore 22 of the housing 18 is a battery cell 14. The battery cells 14 generally have a cylin drical shape in the embodiment shown. However, any other shape battery cell 14 may be used depending on the design requirements. The battery cells 14 are arranged within the counterbore 22 such that both ends of the battery cells 14 are exposed via the orifices 20 located at each end of the counter bores 22 through the housing 18. The end of the battery cells 14 will be used for electrical connection between the battery cells 14 and the collector plate 16. The battery pack system 10 also includes a first collector plate 16 arranged on one end of the housing 18 and a second collector plate 16 arranged on another end of the housing 18. In one contemplated embodiment a single collector plate 16 will be used to cover one side of the housing 18. However, it is also contemplated to use multiple differently shaped and
91 5 sized collector plates 16 on one side of the housing 18 and/or multiple collector plates 16 of different size and shapes on the opposite side of the housing 18. The collector plate 16 may have the same shape as that of the housing 18 and the shape may be of any known shape or diameter Such as rectangular, triangular, Square, circular, or any other known shape. Gen erally, the collector plate 16 is made of a metal material. However, it should be noted that the collector plate 16 can be made of any known material such as composite, any known metal, ceramic, natural material, plastic or any other material capable of conducting electricity. In one embodiment con templated an electroless or electrolytic nickel plated alumi num or copper sheet metal will be used for the collector plates 16. The collector plates 16 will have a plurality of orifices 24 therethrough that will align with and mate with the orifices 20 through the housing 18 into the counter bores 22 of the hous ing 18. It should be noted that in one contemplated embodi ment the orifices 24 are generally rectangular in shape, how ever any other shaped orifice 24 Such as Square, circular, triangular, pentagonal or the like may be used depending on the design requirements and environment in which the battery pack system 10 will be used. The collector plate 16 is secured to the housing 18 via any known connecting methodology. In one contemplated embodiment a combination of heat staking and epoxy will be used to connect the collector plate 16 to the housing 18. It should be noted that the orientation of the battery cells 14 within the housing 18, i.e., positive side up or positive side down and the size and shape of the collector plates 16 will allow for different designs and will create a unique and efficient method for creating a combination of parallel and series connections for the battery cells 14 within the electrical system of the electric vehicle. This will allow for many different designs and parameters to be achieved because of the variety of orientation of battery cells 14 within the housing 18 and the size and shape of the collector plates 16 that may be used to create both parallel and series connec tions within the electrical system. Furthermore, the battery cells 14 may be mounted in any other known type of matrix as long as the matrix is clad by a bus bar, collector plate or conductive plate 16. Arranged between the battery cells 14 and the collector plates 16 are a plurality of frangible conductors 12 that create the electrical connection therethrough. Generally, the fran gible conductor 12 is in the shape of a wire, however it is also contemplated to be in any other shape. Such as a ribbon or the like. The conductor 12 generally is bonded to an end surface of the battery cell 14 and to the collector plate 16 at a prede termined position. In the embodiment shown the collector plate 16 may include a recessed portion 26 adjacent to the orifice 24 of the collector plate 16 that exposes the end of the battery cell 14. The recessed area 26 may be of any predeter mined size and shape. In the embodiment shown the recessed area 26 is adjacent to each and every orifice 24 through the collector plate 16. The frangible conductor 12 may also have any type of cross section other than a round or circular such as square, rectan gular, triangular, or any other known cross sectional shape. In one embodiment contemplated the conductor 12 is generally made of an aluminum alloy material. Some aluminum alloy materials that may be used include but are not limited to % aluminum, 99.99% aluminum, 99% aluminum and 1% silicone, or 99.5% aluminum. It should be noted that any other type of metal, ceramic or composite may also be used for the frangible conductor 12 according to the present inven tion. The frangible conductor 12 of the present invention may also include 0.5% by weight magnesium and 50 parts per million nickel along with the aluminums as described above. US 7,923,144 B The use of the magnesium will add strength to the wire 12 which may help bond through any Surface oxide that may be present on the battery cell 14 and collector plate 16. Further more, the nickel may provide a corrosion resistance effect to the frangible conductor 12 for the present invention. It should be noted that any other known Substance may also be added to the conductor 12 along with or in place of one or both of the magnesium or nickel material. It should be noted that the frangible conductor 12 of the present invention generally is in the shape of a round wire that may drawn into any known diameter, however in the embodiment shown the diameter may be anywhere between inches to inches. In particular one diameter may be inches or inches. Furthermore, it is also contemplated that the frangible con ductor 12 may be used in a ribbon form wherein the cross section of the ribbon may be within the range of 0.02 inches by inches to 0.1 inches by 0.01 inches. In one contem plated embodiment a ribbon would have the form of 0.03 inches by inches or 0.08 inches by inches. The frangible conductor 12 is connected to the end of the battery cell 14 and the collector plate 16 via any known connecting methodology both mechanical and chemical. The conductor 12 is bonded to the battery cell 14 and to the collector plate 16 in one contemplated embodiment via an ultrasonic wedge bonding process. However, it should be noted that any other ultrasonic bonding process along with any other type of welding process, mechanical crimping pro cess, conductive epoxy process, Soldering process, installa tion displacement connectors, or any other known bonding process may be used to connect the frangible conductor 12 to both the collector plate 16 and the battery cell 14. In the contemplated ultrasonic wedge bonding process a bonding machine will feed out the conductor 12 either in the form of wire, ribbon or any other shape at a predetermined pace and will have it bonded to both the battery cell substrate and the collector plate Substrate and cut the conductor 12 at an appro priate length. The ultrasonic wedge bonding process uses a computer controlled mechanism that can be programmed to place the wires 12 automatically and then use optical recog nition or other methodology to validate and adjust the posi tions of the conductor 12 with relation to the battery cells 14 and the collector plate 16. It should be noted that aluminum has been chosen as the preferred material for the conductor wire 12 because it is easily tunable to be a frangible conductor 12 for the following reasons. It may be bonded using the ultrasonic process, it is a low cost element and it has high thermal conductivity and low electrical resistivity, which will increase the durability and tunability of the battery pack system 10 in the electric vehicle. It should be noted that high thermal conductivity will allow a Small cross section wire 12 to carry a current Sufficient enough to operate in the high Voltage applications. The Small cross section furthermore is strong enough to Support itself under normal operating conditions of the vehicle and battery pack system 10 but will not add significant strength to the battery pack system 10. This will ensure that the battery pack battery cells 14 will disconnect from the collector plate 16 when a predetermined mechanical force or thermal situation is applied to the battery pack system 10. It should be noted that the diameter, length and path of which the frangible conductor 12 is laid and arranged between the battery cell 14 and collector plate 16 can all be varied to allow for a prede termined fatigue and fracture to occurat predetermined vibra tion levels, mechanical force levels and thermal levels which exceed any predetermined battery pack system 10 limitations throughout the entire electrical vehicle operating system.
92 7 It should be noted that it is contemplated to provide an added level of mechanical support within the battery pack system 10, an added level of corrosion resistance, and arc Suppression by use a silicone dielectric gel to fill the counter bore 22 around the battery cells 14 and cover the frangible conductor wire bond and wire 12. It should be noted that any other type of gel or other gel like Substance may be used to provide the extra mechanical Support, corrosion resistance and arc Suppression as that of a silicone dielectric gel. In operation, the battery pack system 10 will operate within the electric vehicle or industrial equipment to prevent elec trocution and other injuries to first responders or users of such vehicle and equipment. In particular, in the event of an elec tric Vehicle collision, crash or excessive shock, there is a chance that components within the electrical vehicle and specifically the battery cells 14 within the battery pack system 14 could break in a manner which is hazardous to the occu pants of the vehicle, emergency responders, first responders, and any other people involved. In order to combat this poten tial injury situation the frangible conductor 12 is arranged between the battery cells 14 and collector plates 16 and is designed to break or disconnect the collector plate 16 from the battery cells 14 when a predetermined mechanical force is applied to the vehicle in the form of a shock, jolt or other excessive mechanical episode. It should be noted that the two primary hazards within the electric vehicle for which the frangible battery pack system 10 is best used are high Voltages and thermal runaway of the battery cells 14 within the battery pack system 10. It should be noted that for the battery pack system 10 to develop a short, the battery cell parts need to move relative to each other and come in contact with one another. The frangible conductor 12 will break during this relative motion so that if there is contact between the batteries 14, the battery cells 14 will already be disconnected from one another and there will be no short circuit therefrom. Under normal operating conditions of the electric vehicle the high voltage is created by the battery cells 14 are isolated from the occupants and emergency responders. In many fail ure modes the safety systems of the electric vehicle operating system further isolate the high voltages but in the most severe collisions, the high Voltages may become accessible. There fore, the frangible conductors 12 will help reduce the poten tial of electrocution and any electrical danger by disconnect ing the battery cells 14 from the electrical vehicle car system and improve the abuse tolerance of the battery pack system 10. Hence, with the frangible conductors 12 made of, in one contemplated embodiment, aluminum wires from very spe cific alloys that are ultrasonically bonded to the battery cells 14 and to a collector plate 16 the ability to design and adjust the size, length, diameter, and specific materials added to the alloys of the frangible conductors 12 will allow for a variety of breaking points for the frangible conductor 12 tuned to specific mechanical forces encountered in electric Vehicles such that a small five mile per hour bumper collision will not break the frangible conductors 12, however, higher force collisions, both front, rear and side and/or rollovers of an electric vehicle will allow for breaking and disconnecting of the battery cells 14 from the collector plate 16 and hence, the removal of short circuits and possible electrocution by first responders. However, the conductors 12 as designed will still provide adequate current carrying capability and mechanical strength during normal operations of the electrical vehicle. Therefore, the present invention will allow for the mechanical, thermal and electrical behavior of the frangible conductor 12, in this case in the form of a wire, to be cali brated to predetermined values of any known electrical val ues, mechanical values and thermal values based on the US 7,923,144 B design requirements and the environment in which the elec trical vehicle or equipment will be used. Therefore, if mechanical, electrical and thermal scenarios beyond the designed operating conditions of the battery pack system 10 are encountered the conductors 12 will disconnect by some type of mechanical or thermal means. These thermal means may include but are not limited to an over current, runaway combustion products, runaway heating, electrical arcing, reversal of battery cell Voltage and high impedance connec tions. Examples of Such mechanical means or occurrences through which the frangible conductors 12 may disconnect may include but are not limited to cyclic loading and fatigue, ultimate tensile strength and bonding failure in the interface between the battery cells 14 and the collector plates 16. Hence, the tunable frangible battery pack system 10 is capable of being designed for any known electric Vehicle application and will provide piece of mind and safety to first responders responding to accidents involving electric vehicles that have high voltage battery packs from fear of electrocution and other injuries during rescue of occupants within the electric vehicles during Such situations. The present invention has been described in an illustrative manner. It is to be understood that the terminology which has been used is intended to be in the nature of words of descrip tion rather than of limitation.
