Description
Technical Field
The present invention relates to a jump starter (jump starter) having a battery detection system for providing safety, and a system and method for detecting when the jump starter is connected to a depleted or discharging battery being jump started.
The present invention also relates to a jump starter, system and method having a shunt (i.e., power switch) device and a safety switch. For example, a power or safety switch (e.g., a smart switch) across the starter includes a primary current path and one or more secondary bypass current paths to provide the one or more bypass current paths to the safety switch to protect the primary current path through the safety switch from damage by current overload (e.g., a welded contact of the safety switch).
Background
There are multiple jump starters for charging or boosting a depleted or discharged battery (e.g., a vehicle battery).
In addition, high currents are required to bridge across a battery (e.g., a vehicle battery) that is starting to run out or discharge. Generally, the larger the vehicle, the higher the current. The cold weather makes the problem worse because the mechanical parts of the starter and engine are more difficult to move in cold conditions. Problems arise in how to deliver high currents to the vehicle battery and starter. If not properly designed, the power transfer of lithium batteries increases to the point that they may damage conductors and switching devices.
In order to provide safety in a jump starter, a safety switch must be provided in the design. Such safety switches, when turned off, do not allow power to be transferred to a jump starter clamp connected to a depleted or discharged battery. When the safety switch is closed, the power required to start the vehicle across is provided. The safety switch is typically a relay or FET design.
The advantage of the relay is that it is very durable. The disadvantage is that the contacts can stick and are relatively slow when turned off or closed. Another disadvantage is that it generally takes up a lot of space.
The advantage of FETs is that they are small and that they switch on and off very quickly. Their disadvantages are more fragile (e.g. thermal runaway and load sharing are critical).
The present invention also relates generally to an apparatus for cross-starting a vehicle having a depleted or discharged battery. Devices of the prior art are known which provide a pair of electrical connector cables connecting a fully charged battery of another vehicle to an engine starter circuit of a battery-less vehicle, or a portable booster device comprising a fully charged battery which can be connected to the engine starter circuit of a vehicle by a pair of cables.
Problems of the prior art occur when the crossover terminals or clamps of the cable inadvertently contact each other while the other end is connected to the rechargeable battery, or when the positive and negative terminals are connected to opposite polarity terminals in the vehicle to be bridged for bridging, resulting in a short circuit, resulting in sparks and potential damage and/or physical damage to the battery.
Various attempts to eliminate these problems have been made in the prior art. Us patent No. 6,212,054 issued 4/3/2001 discloses a battery booster set that is sensitive to polarity and is able to detect correct and incorrect connections before providing a path for current flow. The device uses a set of LEDs connected to an optical coupler that is oriented by a control circuit. The control circuit controls a solenoid assembly that controls the path of the power current. The control circuit causes power current to flow through the solenoid assembly only if the contact points of the booster cable clip connection have been properly formed.
Us patent No. 6,632,103 issued 10/14/2003 discloses an adaptive booster cable connected to two pairs of clamps that are attached to two batteries, respectively, to transfer power from one battery to the other. The adaptive booster cable includes a polarity detection unit, a switching unit, and a current detection unit connected to each clamp, both of which are disposed between two pairs of clamps. After the polarity detection unit senses the polarity of each clamp, the switching unit creates an appropriate connection between the two batteries. Therefore, the positive electrode terminal and the negative electrode terminal of the two batteries are correctly connected based on the detection result of the polarity detection unit.
Us patent No. 8,493,021 issued 2013, 7, 23 discloses an apparatus that monitors the voltage of the battery of a vehicle to be cross-over started and the current delivered by the cross-over starter battery to determine if a proper connection has been established and to provide fault monitoring. The system can only operate if the proper polarity is detected. The voltage is monitored to determine open circuit, open conductive clamps, shunt cable faults, and solenoid fault conditions. The current through the shunt cable is monitored to determine if there is a risk of battery explosion, and for an over-current condition that exhibits an over-temperature condition, this may lead to a fire. The system includes an internal battery for providing power to a battery of a vehicle to be cross-over started. Once the vehicle is started, the unit is automatically electrically disconnected from the battery of the vehicle.
Us patent No. 5,189,359 issued 2.23 1993 discloses a jumper cable apparatus having two bridge rectifiers for generating a reference voltage, a four-input decoder for determining which terminals to connect based on a comparison of the voltage at each of the four terminals with the reference voltage, and a pair of relays for achieving a correct connection according to the determination of the decoders. Unless only one terminal of each battery has a higher voltage (indicated as "positive" terminal) than the reference voltage and one has a lower voltage (indicated as "negative" terminal) than the reference voltage, no connection will be made, and therefore, two high voltage terminals may be connected and two low voltage terminals may be connected. Once the appropriate relay device is closed, current flows. The relay device is preferably a MOSFET combined with a series array of photodiodes that produce a MOSFET gate-on potential when the decoder output causes the LED to emit light.
U.S. patent No. 5,795,182 issued 8 and 18 in 1998 discloses a set of polarity independent battery jumper cables for bridging a first battery to a second battery. The apparatus includes a relative polarity detector for detecting whether the two batteries are in a cross configuration or a parallel configuration. The three-position high current capacity crossover pivot switch is responsive to a relative polarity detector for automatically connecting the positive terminals of the two batteries together and connecting the negative terminals of the two batteries together, whether the detected configuration is crossover or parallel, and an under-current detector and delay circuit for returning the device to its ready and unconnected state after the device has been disconnected from one of the batteries. The cross-pivot switch includes two pairs of contacts, and a pivot arm that pivots about two separate points to ensure complete electrical contact between the pairs of contacts. The invention can also be used to produce a battery charger that can be connected to a battery regardless of the polarity of the battery.
Us patent No. 6,262,492 issued 7/17/2001 discloses a car battery for precisely coupling an active power source to a faulty or uncharged battery across its cable that includes a relay switch circuit connected to the power source and the battery by two current conductor pairs. The first voltage polarity recognition circuit and the second voltage polarity recognition circuit are connected to the power supply and the battery through respective pairs of voltage conductors to recognize polarities of the power supply and the battery, respectively. The logic recognition circuit generates a control signal influenced by the polarity of the power supply and the battery, and the driving circuit controlled by the control signal from the logic recognition circuit drives the relay switch circuit to enable the two poles of the power supply to be accurately connected to the two poles of the battery.
U.S. patent No. 5,635,817 issued 6/3 1997 discloses a vehicle battery charging device that includes a control housing having a cable that includes a current limiting device to prevent exceeding a predetermined maximum charging current of about 40 to 60 amps. The control housing comprises polarity detection means for verifying the correct polarity of the connection of the terminals of the two batteries and electrically disconnecting the two batteries if there is an incorrect polarity.
Us patent No. 8,199,024 issued 6/12 2012 discloses a safety circuit in a low voltage connection system that disconnects two low voltage systems until it is determined that the connection is safe. When the safety circuit determines that an unsafe condition does not exist and it is safe to connect the two low voltage systems, the safety circuit may connect the two systems through a "soft start" that provides a connection between the two systems for a period of time that reduces or prevents an induced voltage spike on one or more of the low voltage systems. When one of the low voltage systems has a fully discharged battery incorporated therein, a method is used to detect the proper polarity of the connection between the low voltage systems. The polarity of the discharged battery is determined by passing one or more test currents through the discharged battery and determining whether a corresponding voltage rise is observed.
5,793,185 issued 8.11.1998 discloses a hand-held jump starter having a control assembly and circuitry to prevent overcharging and improper connection to a battery.
While the prior art attempts to solve the above-described problems, each of the prior art solutions has other drawbacks, namely complexity, cost or likelihood of failure. Accordingly, there is a need in the art for further improvements in vehicle jump starting devices.

Safety switch
The invention also relates to a jump starter with a safety switch, i.e. a power switch, and also to a specific safety switch for a jump starter. The safety switch includes a first current path in combination with one or more additional current paths (e.g., one or more additional bypass current paths) to split (share) the current through the switch, e.g., at least protect the first current path through the switch.
For example, the safety switch may comprise a primary relay in parallel with a secondary bypass relay. Alternatively, the safety switch may comprise a primary relay connected in parallel with one or more secondary bypass FETs. Alternatively, the safety switch may comprise one or more primary FETs in parallel with a secondary bypass relay.
The use of a combination of both relays and FETs (e.g., relays, FETs) in a switch structure may take advantage of and focus on the use of at least one relay and at least one FET while helping to eliminate the drawbacks of using only relays or FETs. At least one FET may be added in parallel with at least one relay to help split current and help minimize the space required for a larger relay. The at least one may be turned on and off as needed, and may also be pulse width modulated (PMW) to control how much current is split.
The primary and secondary current paths (e.g., relays, FETs, or a combination thereof) may equally share the amount of current through each device in a parallel arrangement. However, the switches may be arranged, for example, such that the primary current path handles or accommodates more or most of the current, and the secondary current path handles or accommodates less or minimal current through the switch (e.g., a smart switch) when activated or turned off.
For example, the primary current path is configured to handle or hold eighty to eighty-five percent (i.e., 80% to 85%) of the total current through the switch when activated or turned off, and the secondary current path is configured to handle or hold ten to fifteen percent (i.e., 10% to 15%) of the total current through the switch when activated or turned off.
Relay/FET conductor
Conductors (e.g., heavier gauge conductors, copper conductors, aluminum conductors, bus bars) may connect the at least one relay and the outlet end of the at least one FET. The size or rating of the conductor may control the amount of current flowing through each of the at least one relay and the at least one FET. Also, the conductors may be copper, aluminum or some other conductive or highly conductive metal, and may be shaped (e.g., stamped, formed, cut, machined) for optimal connection between the at least one relay and the at least one FET.

A programmable microcontroller unit (MCU) 1 receives various inputs and generates information and control outputs. The programmable MCU 1 also provides flexibility to the system by allowing updates of functions and system parameters without requiring any changes in hardware. According to one example embodiment, an 8-bit microcontroller with a 2K 15-bit flash memory is used to control the system. One such microcontroller is HT67F30, which is commercially available from Holtek semiconductor Inc.
The vehicle battery reverse sensor 10 monitors the polarity of the vehicle battery 72 when the hand-held battery booster device is connected to the electrical system of the vehicle. As described below, the booster device prevents the lithium battery pack from being connected to the vehicle battery 72 when the terminal of the battery 72 is connected to the wrong terminal of the booster device. The car battery isolation sensor 12 detects whether the car battery 72 is connected to the booster device and prevents the lithium battery pack from being connected to the output terminal of the booster device unless there is a good (e.g., rechargeable) battery connected to the output terminal.
The smart switch FET circuit 15 switches the hand-held battery booster lithium battery to the electrical system of the vehicle only when the vehicle battery is determined by the MCU 1 to be present (in response to the detection signal provided by the isolation sensor 12) and connected with the correct polarity (in response to the detection signal provided by the reverse sensor 10). The lithium battery temperature sensor 20 monitors the temperature of the lithium battery pack 32 to detect overheating due to high ambient temperature conditions and excessive current consumption during a jump start. The lithium battery voltage measurement circuit 24 monitors the voltage of the lithium battery pack 32 to prevent the voltage potential from rising too high during a charging operation and falling too low during a discharging operation.
The lithium battery reverse charge protection diode 28 prevents any charge current delivered to the vehicle battery 72 from flowing back from the electrical system of the vehicle to the lithium battery pack 32. The flash LED circuit 36 is provided to provide a flash function for enhancing the light under the hood of the vehicle in dark conditions, and to provide SOS and flash lighting functions for safety purposes when the vehicle may be disabled in potentially dangerous locations. The voltage regulator 42 provides for regulation of the internal operating voltage for the microcontroller and sensors. The on/off manual mode and flash switch 46 allows the user to control the powering on of the hand-held battery booster device, to control manual override operation if the vehicle is battery-free, and to control the flash function. The manual push button is only active when the booster device is energized. This button allows the user to jump start the vehicle with a missing battery or a battery voltage that is so low that it cannot be automatically detected by the MCU. When the user presses and holds the manual override button for a predetermined period of time (e.g., three seconds) to prevent accidental activation of the manual mode, internal lithium ion battery power is switched to the vehicle battery connection port. The only exception to manual override is the reverse connection of the car battery. If the car battery is connected in reverse, the internal lithium battery power will never switch to the vehicle battery connection port.
The USB charging circuit 52 converts power from any USB charger power supply into a charging voltage and charging current for charging the lithium battery pack 32. The USB output 56 provides a USB portable charger for charging smart phones, tablets, and other chargeable electronic devices. The operation indicator LED 60 provides a visual indication of the lithium battery capacity status as well as an indication of the intelligent switch activation status (indicating that power is being provided to the electrical system of the vehicle).
Detailed operation of the hand-held booster device will now be described with reference to the schematic diagrams of fig. 2A-1, fig. 2A-2, fig. 2A-3, fig. 2A-4, fig. 2B-1, fig. 2B-2, fig. 2B-3, fig. 2B-4, fig. 2C-1, fig. 2C-2, and fig. 2C-3. As shown in fig. 2A-2, the microcontroller unit 1 is central to all inputs and outputs. The reverse battery sensor 10 includes an optically coupled isolator phototransistor (4N 27), the optically coupled isolator phototransistor (4N 27) being connected at input pins 1 and 2 to the terminal of the vehicle battery 72 through diode D8 in the lead conductor of pin 1 (associated with negative terminal CB-such that if the battery 72 is connected to the terminal of the booster device with the correct polarity, the optical coupler LED 11 will not conduct current and thus be disconnected providing a "1" or high output signal to the MCU 1. The automotive battery isolation sensor 12 includes an optically coupled isolator phototransistor (4N 27) that is connected at input pins 1 and 2 to the terminal of the vehicle battery 72 through diode D7 in the lead conductor of pin 1 (associated with positive terminal CB +) such that if the battery 72 is connected to the terminal of the booster device with the correct polarity, the optical coupler LED 11A will conduct current and thus be turned on providing a "0" or low output signal to the MCU indicating the presence of a battery across the output terminal of the hand-held booster device.
If the car battery 72 is connected to the hand-held booster device with the opposite polarity, the optical coupler LED 11 of the reverse sensor 10 will conduct current, providing a "0" or low signal to the microcontroller unit 1. Furthermore, if no battery is connected to the hand-held booster device, the optical coupler LED 11A of the isolation sensor 12 will not conduct current and therefore be disconnected, providing a "1" or high output signal to the MCU indicating that no battery is connected to the hand-held booster device. Using these specific inputs, the microcontroller software of MCU 1 can determine when it is safe to turn on smart switch FET 15, thereby connecting the lithium battery pack to the crossover terminal of the booster device. Thus, if the car battery 72 is not connected to the booster device at all, or is connected in the opposite polarity, the MCU 1 can keep the smart switching FET 15 turned on, thereby preventing spark/short-circuiting of the lithium battery pack.
As shown in fig. 2B-2, the FET smart switch 15 is driven by the output of the microcontroller 1. The FET intelligent switch 15 includes three FETs (Q15, Q18, and Q19) in parallel that distribute the power distribution from the lithium battery pack to the FETs. When the microcontroller output is driven to logic low, FET 16 is in a high resistance state and therefore does not allow current to flow from internal lithium battery negative contact 17 to the vehicle battery 72 negative contact. When the microcontroller output is driven to logic high, FET 16 (Q15, Q18, and Q19) is in a low resistance state, allowing current to flow freely from internal lithium battery pack negative contact 17 (LB-) to automobile battery 72 negative contact (CB-). In this manner, the microcontroller software controls the connection of the internal lithium battery pack 32 to the vehicle battery 72 to cross-start the vehicle engine.
Referring back to fig. 2A-1, the internal lithium battery pack voltage can be accurately measured using one of the analog-to-digital inputs of the microcontroller 1 and the circuit 24. The circuit 24 is designed to sense when the voltage of the main 3.3V regulator 42 is on and to turn on the transistor 23 when the voltage of the regulator 42 is on. When transistor 23 is on, it turns on FET 22, providing a conductive path to voltage divider 21 for the positive contact (lb+) of the internal lithium battery, allowing a lower voltage range to be brought to the microcontroller to be read. Using this input, the microcontroller software can determine whether the lithium battery voltage is too low during a discharging operation or too high during a charging operation, and take appropriate action to prevent damage to the electronic components.
Still referring to fig. 2A-1, the temperature of the internal lithium battery pack 32 may be accurately measured by two Negative Temperature Coefficient (NTC) devices 20. These are means to reduce their resistance when their temperature increases. The circuit is a voltage divider that brings the result to two analog-to-digital (a/D) inputs on the microcontroller 1. The microcontroller software can then determine when the internal lithium battery is too hot to allow for a cross-over start, thereby increasing the safety of the design.
The main voltage regulator circuit 42 is designed to convert the internal lithium battery voltage to a regulated 3.3 volts, which regulated 3.3 volts is utilized by the microcontroller 1 and other components of the booster device for internal operating power. Three lithium battery reverse charge protection diodes 28 (see fig. 2B-1) are in place to allow current to flow only from the internal lithium battery pack 32 to the car battery 72, rather than from the car battery to the internal lithium battery. In this way, if the automotive electrical system is charged from its alternator, it cannot back charge (and thus damage) the internal lithium battery, providing another level of safety. The main power on switch 46 (fig. 2A-1) is a combination that allows for double pole, double throw operation such that if the product is in an off state, the product can be on with one push or if the product is in an on state, the product can be off with one push. The circuit also uses the microcontroller output 47 to "keep the power on" when the power is activated by the on switch. When the switch is pressed, the microcontroller transitions the output to a high logic level to keep the power on when the switch is released. In this way, the microcontroller maintains control of when the power is turned off when the on/off switch is again activated or when the lithium battery voltage becomes too low. The microcontroller software also includes a timer that turns off power after a predetermined period of time (e.g., such as 8 hours) if not used.
The flash LED circuit 45 shown in fig. 2B-3 controls the operation of the flash LED. The two outputs from the microcontroller 1 are dedicated to two separate LEDs. Thus, the LEDs may be software controlled independently for gating and SOS modes, providing another safety feature for the booster device. The LED indicators provide feedback that the operator needs to understand what the product is happening. Four individual LEDs 61 (fig. 2A) are controlled by respective individual outputs of the microcontroller 1 to provide an indication of the remaining capacity of the internal lithium battery. These LEDs are controlled in a "fuel gauge" format with 25%, 50%, 75% and 100% (red, yellow, green) capacity indications. The LED indicator 63 (fig. 2B-4) provides a visual warning to the user when the vehicle battery 72 is connected in the opposite polarity. The "boost" and "on/off" LEDs 62 provide visual indications when the booster device provides a cross-over start power and when the booster device is on, respectively.
A USB output circuit 56 (fig. 2C-1) is included to provide a USB output for charging a portable electronic device (e.g., a smart phone) from the internal lithium battery pack 32. The control circuit 57 from the microcontroller 1 allows switching on and off the USB output 56 by software control to prevent the capacity of the internal lithium battery from becoming too low. The USB output is brought outside the device on a standard USB connector 58, the standard USB connector 58 comprising the standard voltage divider required to allow for charging of certain smartphones that require it. The USB charging circuit 52 allows the internal lithium battery pack 32 to be charged using a standard USB charger. The charge input uses a standard micro USB connector 48 that allows the use of standard cables. The 5V potential provided from a standard USB charger is up-converted to the 12.4V DC voltage required to charge the internal lithium battery pack using a DC-DC converter 49. The DC-DC converter 49 may be switched on and off via a circuit 53 by an output from the microcontroller 1.
Thus, if the a/D input 22 measures that the battery voltage is too high, the microcontroller software may turn off the charge. Additional safety is provided to help eliminate overcharging of the internal lithium battery using a lithium battery charge controller 50 that provides charge balancing to the internal lithium battery cells 51. The controller also provides safety redundancy for eliminating overdischarge of the internal lithium battery.
Fig. 3 is a perspective view of a handheld device 300 according to an exemplary embodiment of the present invention. 301 is an on switch. 302 shows an LED "fuel gauge" indicator 61. 303 shows a 12 volt output port connectable to a cable device 400, as will be described further below. 304 shows a flash control switch for activating the flash LED 45. 305 is a USB input port for charging an internal lithium battery and 306 is a USB output port for providing charge from the lithium battery to other portable devices (e.g., smart phones, tablets, music players, etc.). 307 is a "boost on" indicator that power is being supplied to the 12V output port. 308 is a "reverse" indicator that shows that the vehicle battery is connected incorrectly with respect to polarity. Reference numeral 309 is an "on" indicator that the device is powered on to operate.
Fig. 4 shows a jumper cable apparatus 400 specifically designed for use with the handheld apparatus 300. The device 400 has a plug 401 configured to plug into the 12 volt output port 303 of the handheld device 300. A pair of cables 402a and 402b are integrated with the plug 401 and connected to battery terminal holders 403a and 403b through ring terminals 404a and 404b, respectively. The port 303 and plug 401 may be sized such that the plug 401 will fit into the port 303 only in a particular orientation, thereby ensuring that the clip 403a will correspond to a positive polarity and the clip 403b will correspond to a negative polarity, as shown above. In addition, the ring terminals 404a and 404b may be disconnected from the jig and directly connected to terminals of the vehicle battery. This feature may be used, for example, to permanently attach the cables 302 a-302 b to the battery of the vehicle. In case the battery voltage becomes depleted, the handheld booster device 300 can be connected to the battery correctly, very simply by inserting a plug 401 into the port 303.
Shunt switch arrangement and safety switch
A cross-over starter 510 according to the invention is shown in fig. 5 with a power switch 511 (e.g. a smart switch), the power switch 511 having a shunt arrangement according to the invention. The intelligent switch may be connected to and controlled by a microcontroller of the crossover starter 510.
The crossover starter 510 includes a lithium ion rechargeable battery 522, a power switch 511, a conductor 520 (e.g., heavy duty conductor, conductive metal plate or strip, bus bar), a positive (+) battery clamp 24, and a negative (-) battery clamp 526, as shown in fig. 5.
The positive (+) terminal of the lithium-ion rechargeable battery 522 is connected to the positive (+) battery terminal, and the negative (-) terminal of the lithium-ion rechargeable battery 522 is connected to the power switch 511.
The power switch 511 includes a relay 512 (i.e., a primary switch) having a switch 512a and a coil 512b, and FETs 514, 516, 518 (i.e., secondary switches) arranged in parallel with the relay 512. FET1 514, FET2 516, and FETN 518 include gate 1, gate 2, gate N, respectively. The outputs of the relay 512 and FETs 514, 516, 518 are connected to a common conductor 520.
Conductor 520 is constructed or arranged to accommodate a large amount of current. For example, the conductor 520 is a heavy-duty conductor made of a conductive metal such as copper or aluminum and is configured as a large gauge wire, plate, rod, bar, tube, bus bar, or other suitable configuration for handling or accommodating large currents without being damaged. For example, the conductor 520 may be configured, designed, or customized to accommodate the same, similar, or different current levels or current levels (current rates) output from the relay 12 and FETs 514, 516, 518 to the conductor 520 leading to the negative (-) cell clamp 524. For example, due to the configuration of the conductor 520, the FETs 514, 516, 518 may deliver increased or decreased current levels from different FETs to minimize damage to the relay 512 and/or FETs 514, 516, 518 due to high current levels and/or power surges.
The relay 512 may be configured to accommodate the same or similar amounts of current as the FETs 514, 516, 518. Alternatively, the relay 512 may be configured to accommodate a much larger current than the FETs 514, 516, 518. For example, FETs 514, 516, 518 are bypass switches that accommodate approximately ten percent (10%) to fifteen percent (15%) of the current through power switch 511, and relay 512 is configured to accommodate approximately eighty-five percent (85%) to ninety percent (90%) of the current through power switch 511.
To begin a charging operation across starter 510, relay switch 512a is closed to charge the depleted or discharged battery properly connected to positive battery clamp 524 and negative battery clamp 526. For example, a portion of the current from the lithium ion battery 522 begins to flow through the relay 512, and after a slight delay (e.g., a 1/100 millisecond delay timing), the current begins to flow through the FETs 514, 516, 518. Thus, the switching operation of the power switch 511 may include a sequence of initially closing the relay 512 and then subsequently closing the FETs 514, 516, 518. This sequence prevents the relay 512 and FETs 514, 516, 518 from being damaged by the current through the power switch 511.
Further, the operation may include a sequence of turning off the power switch 511 (e.g., after initial closure) by first turning off FETs 514, 516, 518, and then subsequently turning off relay 512. For example, the relay 512 may be turned off after a slight delay (e.g., a delay timing of 1/100 ms) after the FET turns off.
Thus, the entire sequence of switching the power switch 511 is that the relay 512 is turned off first, FETs 514, 516, 518 are turned off second, FETs 514, 516, 518 are turned on first, and the relay 512 is turned on second.
Current flows through the relay 512 and FETs 514, 516, 518 into the conductor 520 and the current is combined in the conductor 520.
Having thus described the invention, it will be apparent to those skilled in the art that the invention may be varied in many ways without departing from the spirit or scope of the invention. Any and all such modifications are intended to be included within the scope of the following claims.
Battery detection for providing security
The jump starter according to the invention comprises both a battery detector, for example depleted or discharged, and a battery detector, which is actively depleted or discharged. For example, a depleted or discharged battery detector is a vehicle battery detector (e.g., an automotive battery detector), while an actively depleted or discharged battery detector is an active vehicle battery detector (e.g., an active automotive battery detector).
For example, a circuit of a depleted or discharged battery detector 610 according to the present invention for use in a jump starter according to the present invention is shown in fig. 6.
The depleted or discharged battery detector 610 includes one or more opto-isolators 817C to detect the presence of a depleted or discharged battery.
The jump starter according to the present invention includes a system that uses information from the depleted or discharged battery detector 610 and inputs from the short circuit detector, the depleted or discharged battery reverse polarity detector, and the actively depleted or discharged battery detector to decide whether to turn on power from the jump starter to the depleted or discharged battery by closing a jump starter switch (e.g., a smart switch) during a charge or boost cycle (e.g., an automatic boost mode).
If during the boost cycle (e.g., after the smart switch has been closed), the depleted or discharged battery and the internal battery of the jump starter are so close in potential that the auto-depleted or discharged battery detector does not detect current, the system temporarily turns off the smart switch and the depleted or discharged battery detector verifies that the depleted or discharged battery is still attached to the battery clamp of the jump starter.
For example, a circuit of an actively depleted or discharged battery detector 640 according to the present invention for use in a jump starter according to the present invention is shown in fig. 7.
The active depleted or discharged battery detector 640 includes an operational amplifier based circuit for measuring the current flowing through the smart switch (i.e., the current from the internal battery across the starter to the depleted or discharged battery).
The "zero point" is set so that the current can be measured in both directions (i.e., from the internal battery of the across-from starter to the depleted or discharged battery, and from the depleted or discharged battery to the internal battery of the across-from starter).
When the battery clamp is connected to a depleted or discharged battery, the actively depleted or discharged battery detection value (AN 1) is below "zero" when the depleted or discharged battery voltage is above the internal battery voltage of the crossover starter. Thus, after the depleted or discharged battery detector detects a depleted or discharged battery at the battery clamp, and before entering the auto boost mode, the system checks the signal to prevent a high voltage depleted or discharged battery from being connected to the system.
During automatic boosting, the current is measured continuously to ensure that the battery clamp does not suddenly open and short to the vehicle chassis, for example.
Conversely, if the across-starter does not block the diode, current may flow in both directions between the internal battery of the across-starter and the depleted or discharged battery. For example, if a depleted or discharged battery is extremely discharged (e.g., less than a vehicle alternator voltage), an algorithm may be used to allow the internal battery of the across-starter to be recharged by the depleted or discharged battery.
If current flow from the depleted or discharged battery to the internal battery of the jump starter is detected, the algorithm may consider the battery capacity, maximum charge current, and battery temperature of the internal battery of the jump starter to determine how long to allow the flow of the reverse charge current from the depleted or discharged battery to the internal battery of the jump starter.
If the above parameters are met or if an auto-timer expires (e.g., in auto-boost mode), the system may then exit charging or boosting the depleted or discharged battery (e.g., smart switch off).
