- a lithium polymer battery pack 32 which stores sufficient energy to jump start a vehicle engine served by a conventional 12 volt lead-acid or valve regulated lead-acid battery.
- a high-surge lithium polymer battery pack includes three 3.7V, 2666 mAh lithium polymer batteries in a 35 IP configuration.
- the resulting battery pack provides 11. IV, 2666Ah (8000Ah at 3.7V, 29.6Wh). Continuous discharge current is 25C (or 200 amps), and burst discharge current is 50C (or 400 amps).
- the maximum charging current of the battery pack is 8000mA (8 amps).
- a programmable microcontroller unit (MCU) 1 receives various inputs and produces informational as well as control outputs.
- the programmable MCU 1 further provides flexibility to the system by allowing updates in functionality and system parameters, without requiring any change in hardware.
- an 8 bit microcontroller with 2K x 15 bits of flash memory is used to control the system.
- One such microcontroller is the HT67F30, which is commercially available from Holtek Semiconductor Inc.
- a car battery reverse sensor 10 monitors the polarity of the vehicle battery 72 when the handheld battery booster device is connected to the vehicle's electric system. As explained below, the booster device prevents the lithium battery pack from being connected to the vehicle battery 72 when the terminals of the battery 72 are connected to the wrong terminals of the booster device.
- a car battery isolation sensor 12 detects whether or not a vehicle battery 72 is connected to the booster device, and prevents the lithium battery pack from being connected to the output terminals of the booster device unless there is a good (e.g. chargeable) battery connected to the output terminals.
- a smart switch FET circuit 15 electrically switches the handheld battery booster lithium battery to the vehicle's electric system only when the vehicle battery is determined by the MCU 1 to be present (in response to a detection signal provided by isolation sensor 12) and connected with the correct polarity (in response to a detection signal provided by reverse sensor 10).
- a lithium battery temperature sensor 20 monitors the temperature of the lithium battery pack 32 to detect overheating due to high ambient temperature conditions and overextended current draw during jump starting.
- a 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 from dropping too low during a discharge operation.
- Lithium battery back-charge protection diodes 28 prevent any charge current being delivered to the vehicle battery 72 from flowing back to the lithium battery pack 32 from the vehicle's electrical system.
- Flashlight LED circuit 36 is provided to furnish a flashlight function for enhancing light under a vehicle's hood in dark conditions, as well as providing SOS and strobe lighting functions for safety purposes when a vehicle may be disabled in a potentially dangerous location.
- Voltage regulator 42 provides regulation of internal operating voltage for the microcontroller and sensors.
- On/Off manual mode and flashlight switches 46 allow the user to control power-on for the handheld battery booster device, to control manual override operation if the vehicle has no battery, and to control the flashlight function. The manual button functions only when the booster device is powered on.
- This button allows the user to jump-start vehicles that have either a missing battery, or the battery voltage is so low that automatic detection by the MCU is not possible.
- the manual override button for a predetermined period time (such as three seconds) to prevent inadvertent actuation of the manual mode, the internal lithium ion battery power is switched to the vehicle battery connect port.
- a predetermined period time such as three seconds
- USB charge circuit 52 converts power from any USB charger power source, to charge voltage and current for charging the lithium battery pack 32.
- USB output 56 provides a USB portable charger for charging smartphones, tablets, and other rechargeable electronic devices.
- Operation indicator LEDs 60 provide visual indication of lithium battery capacity status as well as an indication of smart switch activation status (indicating that power is being provided to the vehicle's electrical system). Detailed operation of the handheld booster device will now be described with reference to the schematic diagrams of Figs. 2A-2C. As shown in Fig. 2A, the microcontroller unit 1 is the center of all inputs and outputs.
- the reverse battery sensor 10 comprises an optically coupled isolator phototransistor (4N27) connected to the terminals of vehicle battery 72 at input pins 1 and 2 with a diode D8 in the lead conductor of pin 1 (associated with the negative terminal CB-), such that if the battery 72 is connected to the terminals of the booster device with the correct polarity, the optocoupler LED 11 will not conduct current, and is therefore turned off, providing a “1” or high output signal to the MCU 1.
- 4N27 optically coupled isolator phototransistor
- the car battery isolation sensor 12 comprises an optically coupled isolator phototransistor (4N27) connected to the terminals of vehicle battery 72 at input pins 1 and 2 with a diode D7 in the lead conductor of pin 1 (associated with the positive terminal CB+), such that if the battery 72 is connected to the terminals of the booster device with the correct polarity, the optocoupler LED 11 A will conduct current, and is therefore turned on, providing a “0” or low output signal to the MCU, indicating the presence of a battery across the jumper output terminals of the handheld booster device.
- 4N27 optically coupled isolator phototransistor
- the optocoupler LED 11 of the reverse sensor 10 will conduct current, providing a “0” or low signal to microcontroller unit 1. Further, if no battery is connected to the handheld booster device, the optocoupler LED 11 A of the isolation sensor 12 will not conduct current, and is therefore turned off, providing a “1” or high output signal to the MCU, indicating the absence of any battery connected to the handheld booster device.
- the microcontroller software of MCU 1 can determine when it is safe to turn on the smart switch FET 15, thereby connecting the lithium battery pack to the jumper terminals of the booster device. Consequently, if the car battery 72 either is not connected to the booster device at all, or is connected with reverse polarity, the MCU 1 can keep the smart switch FET 15 from being turned on, thus prevent sparking/short circuiting of the lithium battery pack.
- the FET smart switch 15 is driven by an output of the microcontroller 1.
- the FET smart switch 15 includes three FETs (Q15, Q18, and Q 19) in parallel, which spreads the distribution of power from the lithium battery pack over the FETs.
- FETs 16 are all in a high resistance state, therefore not allowing current to flow from the internal lithium battery negative contact 17 to the car battery 72 negative contact.
- the FETs 16 are in a low resistant state, allowing current to flow freely from the internal lithium battery pack negative contact 17 (LB-) to the car battery 72 negative contact (CB-).
- the microcontroller software controls the connection of the internal lithium battery pack 32 to the vehicle battery 72 for jumpstarting the car engine.
- the internal lithium battery pack voltage can be accurately measured using circuit 24 and one of the analog-to-digital inputs of the microcontroller 1.
- Circuit 24 is designed to sense when the main 3.3V regulator 42 voltage is on, and to turn on transistor 23 when the voltage of regulator 42 is on. When transistor 23 is conducting, it turns on FET 22, thereby providing positive contact (LB+) of the internal lithium battery a conductive path to voltage divider 21 allowing a lower voltage range to be brought to the microcontroller to be read.
- the microcontroller software can determine if the lithium battery voltage is too low during discharge operation or too high during charge operation, and take appropriate action to prevent damage to electronic components.
- the temperature of the internal lithium battery pack 32 can be accurately measured by two negative temperature coefficient (NTC) devices 20. These are devices that reduce their resistance when their temperature rises.
- 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 jumpstarting, adding safety to the design.
- the main voltage regulator circuit 42 is designed to convert internal lithium battery voltage to a regulated 3.3 volts that is utilized by the microcontroller 1 as well as by other components of the booster device for internal operating power.
- Three lithium battery back charge protection diodes 28 see Fig.
- the main power on switch 46 (Fig. 2A) is a combination that allows for double pole, double throw operation so that with one push, the product can be turned on if it is in the off state, or turned off if it is in the on state.
- This circuit also uses a microcontroller output 47 to “keep alive” the power when it is activated by the on switch. When the switch is pressed the microcontroller turns this output to a high logic level to keep power on when the switch is released.
- the microcontroller maintains control of when the power is turned off when the on/off switch is activated again or when the lithium battery voltage is getting too low.
- the microcontroller software also includes a timer that turns the power off after a predefined period of time, (such as, e.g. 8 hours) if not used.
- the flashlight LED circuit 45 shown in Fig. 2B controls the operation of flashlight LEDs. Two outputs from the microcontroller 1 are dedicated to two separate LEDs. Thus, the LEDs can be independently software-controlled for strobe and SOS patterns, providing yet another safety feature to the booster device. LED indicators provide the feedback the operator needs to understand what is happening with the product.
- Four separate LEDs 61 (Fig. 2A) are controlled by corresponding individual outputs of microcontroller 1 to provide indication of the remaining capacity of the internal lithium battery. These LEDs are controlled in a “fuel gauge” type format with 25%,
- An LED indicator 63 (Fig. 2B) provides a visual warning to the user when the vehicle battery 72 has been connected in reverse polarity.
- “Boost” and on/off LEDs 62 provide visual indications when the booster device is provide jump-start power, and when the booster device is turned on, respectively.
- a USB output 56 circuit (Fig. 2C) is included to provide a USB output for charging portable electronic devices such as smartphones from the internal lithium battery pack 32.
- Control circuit 57 from the microcontroller 1 allows the USB Out 56 to be turned on and off by software control to prevent the internal lithium battery getting too low in capacity.
- the USB output is brought to the outside of the device on a standard USB connector 58, which includes the standard voltage divider required for enabling charge to certain smartphones that require it.
- the USB charge circuit 52 allows the internal lithium battery pack 32 to be charged using a standard USB charger. This charge input uses a standard micro-USB connector 48 allowing standard cables to be used.
- the 5V potential provided from standard USB chargers is up- converted to the 12.4VDC voltage required for charging the internal lithium battery pack using a DC-DC converter 49.
- the DC-DC converter 49 can be turned on and off via circuit 53 by an output from the microcontroller 1.
- the microcontroller software can turn the charge off if the battery voltage is measured to be too high by the A/D input 22. Additional safety is provided for helping to eliminate overcharge to the internal lithium battery using a lithium battery charge controller 50 that provides charge balance to the internal lithium battery cells 51. This controller also provides safety redundancy for eliminating over discharge of the internal lithium battery.

- the device 210 has a plug 212 configured to plug into the 12V output port 122 of the handheld device 110.
- a positive battery cable 214 and a negative battery cable 218 are integrated with the plug 212, and are connected, respectively, to the positive battery clamp 216 and negative battery clamp 220 via ring connectors 216A and 220 A, respectively.
- the 12V outlet port 122 and plug 212 are dimensioned so that the plug 212 will only fit into the 12V outlet port 122 in a specific orientation, thus ensuring that positive battery clamp 216 will correspond to positive polarity, and the negative battery clamp 220 will correspond to negative polarity, as indicated thereon.
- the ring terminals 216A and 216B allows the battery clamps 216 and 229 to be disconnected from the battery cables 214 and 218, and then removably connected directly to the terminals of a vehicle battery. This feature may be useful, for example, to permanently attach the battery cables 214 and 218302b to the battery of the vehicle.
- the handheld booster device 110 can be properly connected to the depleted or discharged vehicle battery very simply by plugging in the plug 212 into the 12V outlet port 122.
