`"A Jump Starter"
`
`INTRODUCTION
`
`5
`
`Field of the Invention
`
`This invention relates to a jump starter system for a battery, especially a vehicle battery.
`
`Prior Art Discussion
`
`10
`
`Jump starter systems for jump starting a flat vehicle battery comprise a pair of leads, each with a
`
`clip such as a crocodile clip at each end to connect with the terminals of the flat battery and a
`
`charged battery of another vehicle. One lead connects the positive terminal of the flat battery to
`
`the positive terminal of a charged battery and a second lead connects the negative terminal of the
`
`15
`
`flat battery to the negative terminal of the charged battery.
`
`Such systems are effective. However in many cases a vehicle with a charged battery is required
`
`and it is often difficult to arrange the vehicles to allow the leads to safely extend between the
`
`batteries.
`
`20
`
`It is also known to provide starter packs comprising a lead acid battery within a battery housing
`
`and leads for extending from the battery housing to the terminal of the flat battery. Such units are
`
`costly, bulky, and heavy, and can generally only be used for large scale commercial applications.
`
`Very often, the unit is not used for some time and the battery charge diminishes so that it is not
`
`25
`
`effective when required.
`
`US5607794, US6002235, US2006/0128209, and US2008/0241653 describe vanous portable
`
`starter systems. In these arrangements, starter cables are connected to a battery.
`
`30
`
`This invention is directed towards providing an engine jump starter system which will address
`
`these issues.

`

`
`Figs. IO to 12 are circuit diagrams for circuits of starter systems of various embodiments.
`
`5 Description of the Embodiments
`
`Referring to Figs. 1 and 2 there is illustrated a jump starter system I according to the invention.
`
`The jump starter system comprises a first crocodile clip 2 having a first handle 3 for connection
`
`to one terminal 4 of a flat vehicle battery 5. The system also comprises a second crocodile clip 7
`
`10
`
`having a second handle 8 for connection to another terminal 9 of the flat vehicle battery 5. An
`
`electrical interconnection lead IO extends between the first clip 2 and the second clip 7. Each clip
`
`has spring biased jaws 11. In the invention there is an on-board starter battery which comprises a
`
`plurality of interconnected batteries 15 which may be of the lithium iron phosphate type. The
`
`battery cells can be of either cylindrical, prismatic or pouch type. The voltage is between 3.2 and
`
`15
`
`3.7 V nominal and of lithium iron chemistry.
`
`As illustrated, the on-board starter batteries 15 extend along the interconnection lead I 0. They
`
`are relatively small and lightweight and can be readily interconnected to form the jump starter
`
`system as illustrated.
`
`20
`
`To jump start a flat battery only one jump lead is required with two simple clip connections 2, 7
`
`to the flat battery 5. Immediate power is supplied to the flat battery 5 without the requirement of
`
`another vehicle with a charged battery. The unit is lightweight and easily stored, for example, in
`
`a vehicle boot or glove compartment. The system has superior starting ability, lifespan, and
`
`25
`
`energy retention than other jump starter systems.
`
`Referring now to Figs. 3 to 5 there is illustrated another jump starter system, 30, according to the
`
`invention. In this case, clips 20, 21 have the clip jaws 11 and have handles 25 of cylindrical
`
`shape. In this embodiment there are two batteries 26 housed within each handle 25, and finger-
`
`30
`
`gripping features 27 are provided to aid user operation. The clips are interconnected by a cable
`
`28, with no need for batteries along the length of the cable in this case.
`
`Referring to Figs. 6 to 9 an alternative jump starter, 50, is shown. The jump starter 50 comprises
`
`a first clip 5 I and a second clip 52 interconnected by a power cable 53. The first clip 51 has a
`
`NOCO Ex. 1007
`Page 7
`
`

`

`WO 2012/080996
`
`PCT/IE2011/000066
`
`- 6 -
`
`housing 55 for a battery of sufficient capacity to provide the full starting power, in this
`
`embodiment of the lithium iron phosphate type. Also, the first clip 51 comprises a pair of jaws
`
`56 having finger grips 57 for pressing together for opening and closing. The housing 55 has a
`
`groove along one side to accommodate the cable 53 during storage. The clip 52 has a similar pair
`
`5
`
`of jaws 56 with finger grips 57.
`
`The starter 50 is used with the clips 51 and 52 separate as shown in Figs. 6 and 7. Power is
`
`provided by the batteries within the housing 55. When not being used, the second clip 52 nests
`
`into the first clip 51 alongside the jaws 56 of the first clip 51, as shown in Figs. 8 and 9.
`
`10
`
`The jump starter 50 involves use of close-proximity high-power batteries of the lithium iron
`
`phosphate type. In this case it is more important to provide safety controls, and this is achieved
`
`by use of a control circuit in the housing 55. Figs.10,11, and 12 illustrate circuits 100,200, and
`
`300 respectively which may be used in the starter of any embodiment. In this case the starter 50
`
`15
`
`employs the circuit 300, however it may employ a different circuit depending on the safety
`
`requirements and battery types and capacities.
`
`Referring to Fig. 10 the circuit 100 comprises batteries 102, a positive lead 103 with a clamp
`
`conductor 104, and a negative lead 105 with a clamp conductor 106. In the positive lead there is
`
`20
`
`a light emitting diode LED2 and a resistor R3 in parallel with a positive thermal coefficient
`
`(PTC) resettable fuse 110.
`
`An integrated circuit IC 1 is connected via a resistor R2 to the positive lead l 03 and is connected
`
`to the negative lead 105 via reverse polarity indicator (LED 1 ). Also, a manual contact switch 115
`
`25
`
`(SWI) is connected on one side to the positive lead 3, and on the other to a Zener diode ZDI, a
`
`resistor RI, in turn linked with a bank of MOSFET switches QI, Q2, and Q3.
`
`The circuit of the jump starter circuit 100 protects from voltage mismatch, reverse polarity, short
`
`circuit, over-discharge, and over-use.
`
`30
`
`The over-current protection element PTC 110 comprises a number of parallel connected positive
`
`thermal coefficient PCB mounted resettable fuses. The number and type thereof is determined by
`
`the power output requirement. The PTC 110 enables normal usage but protects against short
`
`circuit conditions and excessive power demands by achieving a very high resistance, thus
`
`NOCO Ex. 1007

`
`

`

`WO 2012/080996
`
`PCT/IE2011/000066
`
`- 7 -
`
`limiting current flow. Once normal conditions are restored, the PTC 110 drops to a low
`
`resistance. Light emitting diode LED2 and lk 0.25w resistor R3 provide an over-current
`
`indicator. When the PTC 110 goes high resistance, almost all of the jump starter battery l 02
`
`voltage will appear across this device thus providing a current flow to illuminate LED2. When
`
`5
`
`the PTC 110 is in a low resistance state and operating normally, R3 and LED2 are effectively
`
`short circuited.
`
`The battery 102 positive terminal is also connected to the momentary action single pole normally
`
`open switch SWI 115. This switch, the Zener diode ZDI, the resistor RI and Metal Oxide
`
`10
`
`Semiconductor Field Effect Transistors (MOSFETS) QI to Q3 comprise the power-switching
`
`and over-discharge elements.
`
`To activate the jump-starter system it must be connected to a vehicle battery by means of the
`
`positive and negative jaws 56 linked to the conductors I 04 and 106. The activation switch 1 I 5
`
`15
`
`(SWI) is then briefly depressed. This switch may be located at any convenient location of the
`
`housing Current flows from the battery (BAT) via ZD l and RI to the gates of International
`
`Rectifier IRF1324s MOSFETS (or alternates) QI, Q2 and Q3 via their respective gate resistors
`
`R4, R5 and R6. Capacitor Cl is also charged. Once a Vgs of JOY is applied to the MOSFETS
`
`QI, Q2, and Q3 they begin conducting from drain to source with a very low ON state resistance,
`
`20
`
`typically about 0.00033 Ohms for three parallel connected parts.
`
`After the PTC, the positive supply lead 103 is connected to another trio of International Rectifier
`
`IRF 1324s MOSFETS ( or alternates) Q4, Q5 and Q6. These devices are connected in such a way
`
`as to utilise their intrinsic diodes for the purposes of reverse blocking of current. The gate to
`
`25
`
`source is short circuited, thus holding the devices in a permanent OFF state. Should the jump
`
`starter circuit I 00 be connected to a vehicle with a greater voltage than the unit is intended for,
`
`the diodes become reverse biased and no current may flow. This feature protects the jump(cid:173)
`
`starter's internal battery I 02 from potentially dangerous overcharge conditions.
`
`30 Once a successful start has been achieved, the vehicle alternator or charging system will attempt
`
`to return charge to the still-connected jump-starter battery 102 (BAT) via the crocodile clamp
`
`jaws 56. This could be undesirable for certain battery types. Should this situation occur, the
`
`intrinsic diodes in Q4, Q5 and Q6 will become reverse biased, thus preventing this condition
`
`NOCO Ex. 1007

`

`
`PCT/IE2011/000066
`
`- 8 -
`
`A resistor R 7 and a capacitor CI form an RC time constant circuit. When the switch 15 (SW I) is
`
`depressed, CI rapidly charges via R 1. Once in an ON state the gate to source resistance of the
`
`MOS FE TS is very high, in the order of tens of mega Ohms. Thus the run time of the jump starter
`
`circuit 100 can be configured by choice of Cl and R7. Once SWI is released, Cl begins to
`
`5
`
`discharge via R7, When the voltage across Cl drops below the gate threshold voltage of the
`
`MOSFETS, they will rapidly come out of conduction and switch off the output. This auto - off
`
`feature prevents the unit from being left in a constant ON condition with resultant live crocodile
`
`clamps.
`
`10
`
`The RC circuit of R 7 and C 1 provides another important element. As the voltage across C 1 will
`
`require a certain time to reach the gate threshold voltage of the MOSFETS QI, Q2, and Q3, they
`
`will spend a small amount of time in their active region and provide a soft turn on of the jump
`
`starter circuit I 00 power. This prevents transient voltage damage as a result of arcing or high
`
`di/dt induced voltages in the vehicle electrical system.
`
`15
`
`The circuit also protects against accidental reverse polarity connection. Should the operator
`
`inadvertently connect the jump starter circuit 100 backwards to the vehicle battery (i.e. positive
`
`clamp 4 to negative terminal and vice versa), the system offers two levels of protection. The first
`
`level is passive. As the MOSFETS QI through Q3 are non-conductive, no current flow takes
`
`20
`
`place upon connection. This eliminates any potentially dangerous and destructive electrical
`
`arcing at the vehicle battery terminals. Such arcing conditions have been linked with the
`
`destruction of modern vehicle electronic controls. Secondly, current from the vehicle battery
`
`flows via the resistor R2, reverse polarity indicator LED I and the input side of the
`
`semiconductor photo-relay type TLP222 (ICI) thus illuminating LEDI and the input photo LED
`
`25
`
`in ICI. Even if the vehicle battery is severely discharged, the current requirement of ICI is very
`
`small and will in most cases be less than 5 mA. Should the user ignore the reverse polarity
`
`indicator LEDi and depress SW], MOSFET gate current is shunted to ground via an output
`
`MOSFET in ICI thus preventing the successful triggering of Ql-Q3 and damage to the vehicle
`
`or to the jump starter I.
`
`30
`
`The Zener diode ZDI in the gate trigger circuit protects against excessive discharge of the jump
`
`starter battery I 02 (BAT). If the battery has been drained past an acceptable point its potential is
`
`no longer sufficient to overcome ZD I and thus no gate current reaches the MOSFETS QI -Q3.

`
`The jump starter circuit 100 may not then be used until it has been recharged, thus preserving the
`
`life of the battery 102.
`
`Unlike other jump starter protection circuits that require a vehicle battery to be present for
`
`5
`
`correct operation, this jump starter circuit 100 can operate with a completely dead battery or
`
`none at all. However in this case, reverse polarity detection is not available.
`
`The following are advantageous aspects of the invention.
`
`Solid state switching. There are no contacts to weld, burn out, or arc.
`
`10
`
`Soft switching.
`
`Electrical transient protection for modern motor vehicle electronics.
`
`Operator protection from arcing, explosion etc.
`
`Jump starter product protection from misuse.
`
`Battery protection. Ensures long life.
`
`15
`
`Low component count
`
`Cost effective
`
`Passive safety
`
`Visual indicators of fault conditions
`
`No possibility of damage through operator error such as short circuit etc.
`
`20
`
`Low power dissipation. Can be used with traditional lead acid batteries without power
`
`loss.
`
`In other embodiments the role of the switches Q 1-Q3 may alternatively be performed by a device
`
`such as s silicon controlled rectifier for example. This is a simpler circuit, and also would have
`

`
`the benefit of automatic power off upon disconnection and automatic reverse blocking. Referring
`
`to Fig. 1 1 a circuit 200 has a positive lead 203 with a clamp conductor 204 and a negative lead
`
`205 with a clamp conductor 206. There are a PTC fuse 210, a battery 212, and a momentary
`
`switch 215 for performing the same functions as for the circuit 100. However, in this case the
`
`switch 215 is linked with an SCR. Other alternatives may include use of insulated gate bipolar
`
`30
`
`transistors (IGBTs) or standard bipolar transistors.
`
`In a still further embodiment, referring to Fig. 12, a 4-cell Lithium iron battery is connected to a
`
`positive jump-starter clamp by means of a number of parallel connected positive thermal
`
`coefficient (PTC) type resettable fuses. The negative battery lead is directly connected to the

`
`PCT/IE2011/000066
`
`- IO -
`
`negative jump starter clamp. A warning light emitting diode LEDI and its associated series
`
`limiting resistor are connected in parallel with the PTC devices. During normal engine starting
`
`operation the PTC devices are cold and exhibit a low resistance thus permitting normal current
`
`flow. As there is little voltage drop across the devices in this state, LEDI is extinguished.
`
`5
`
`Should any of the following fault conditions occur: clamp short circuit, reverse connection to
`
`vehicle or incorrect voltage selection, then a larger than normal current flow will result causing
`
`the PTC devices to rapidly warm up and exhibit a high resistance thus limiting current flow to a
`
`very low level and preventing damage to the jump starter unit or the flat battery. As most of the
`
`10
`
`battery (BA Tl) voltage will now be developed across the PTC devices, LED I is illuminated thus
`
`informing the user that a fault condition has occurred. Once the fault is removed, LEDI is
`
`extinguished and after a short delay the PTCs return to normal temperature and resistance and
`
`normal operation is resumed.
`
`15
`
`Transient voltage suppression diodes (TVS) DI and 02 are connected across the output leads.
`
`These devices (typical rating of 5kW each) prevent any transient or induced voltages from
`
`damaging the vehicle or the starter. Unlike the typical sure protection employed in a traditional
`
`jump starter which employs voltage dependent resistor (VDR) type devices, the TVS can
`
`respond much quicker and quench much more energy thus providing a better solution.
`
`20
`
`It will be appreciated that the invention provides for much more convenient jump starting. It
`
`allows a user to carry the starter in the vehicle, and avoids need to hook up to another vehicle
`
`and all of the attendant disadvantages.
`
`25
`
`The invention is not limited to the embodiments described but may be varied in construction and
`
`detail.
