Description

[Technical Field]

[0001] This utility model relates to the technical field of automobile emergency starting devices, and specifically to a farad supercapacitor starting power supply with battery charging function. [Background technology]

[0002] Existing emergency start power supplies primarily use lithium battery technology, which requires regular charging and maintenance (prolonged non-charging can cause permanent damage to lithium batteries), cannot be stored for long periods in extreme vehicle temperatures (they are prone to expansion and spontaneous combustion in high-temperature environments inside vehicles), cannot be used in extreme temperature environments (supercapacitors can operate in temperatures between -70°C and -40°C), and have a short service life (supercapacitors have a service life of more than 10 years). Additionally, commercially available products only provide emergency start functionality, and in the event of a severe battery power shortage, they are charged by an external power source before starting or assisting the start. For example, in the case of an ultra-large-displacement vehicle, if the battery is completely discharged in cold weather, the conventional lithium battery start power supply will not function due to the extreme low temperature, requiring rescue. The specification notes that the prior art does not yet have a 2-in-1 product that combines the functions of a farad supercapacitor and battery charging.

[0003] Therefore, there is an urgent need for a new type of starting power supply that is safe, reliable, maintenance-free and has integrated charging function. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of this, this utility model aims to solve the problems of the prior art, such as safety hazards (e.g., spontaneous combustion of lithium batteries) in emergency starting power supplies, high maintenance costs, inability to adapt to extreme temperature environments, and inability to provide assisted starting through charging when the battery is severely low in power, by using farad supercapacitor technology and combining it with an intelligent switching circuit, to provide a farad supercapacitor starting power supply with battery charging function that achieves the dual functions of emergency starting a vehicle and battery charging. [Means for solving the problem]

[0005] To achieve the above objectives, this utility model provides the following technical solutions:

[0006] In accordance with the above objectives, the present invention provides a farad supercapacitor starting power supply with battery charging function, which includes a starting power supply housing, a farad supercapacitor pack installed in the starting power supply housing, a main control circuit board, and an alligator clip output interface, the main control circuit board further includes a USB-C charging port connected to an external charging source, a switching circuit for managing power path switching, and an MCU control circuit; The alligator clip output interface is connected to a vehicle battery through an alligator clip, and the switching circuit includes a capacitor pack charging switching circuit and a battery charging switching circuit; The capacitor pack charging switching circuit is electrically connected to the farad supercapacitor pack and a USB-C charging port connected to an external charging source; the battery charging switching circuit is electrically connected to the alligator clip output interface and a USB-C charging port connected to an external charging source; the MCU control circuit is electrically connected to the control side of the switching circuit; The MCU control circuit is configured to monitor the status of the external charging source and the vehicle battery, and output a control signal to the switching circuit for power path switching management; when the USB-C charging port is connected to an external charging source and the alligator clip output interface is connected to a vehicle battery that is short of power, the MCU control circuit will configure the switching circuit to enter a battery charging mode and control it to guide the charging current from the external charging source to the vehicle battery to charge the vehicle battery, thereby providing a farad supercapacitor starting power supply with battery charging function.

[0007] In a further solution of the present invention, the power input connection point of the switching circuit is a USB-C charging port of an external charging source, and the power output connection point of the switching circuit is controlled by the MCU control circuit to cause the switching circuit to switch to a farad supercapacitor pack or a vehicle battery.

[0008] In a further solution of the present invention, the MCU control circuit is for monitoring the status of the starting power supply and the vehicle battery, and sending a control signal to control the switching circuit.

[0009] In a further solution of the present invention, the switching type of the switching circuit is at least one of an NMOS switch, a PMOS switch or a relay switch, and supports three switch types: NMOS, PMOS or relay.

[0010] As a further solution of this invention, the Farad supercapacitor starting power supply supports switching between three working modes: automatic starting, manual starting and dead battery starting.

[0011] As a further solution of this utility model, the farad supercapacitor starting power supply with battery charging function comprises: When the alligator clip output interface is connected to a vehicle battery that is running out of power, the remaining power of the vehicle battery is used to reverse charge the farad supercapacitor pack, and after charging is complete, when the user ignites the vehicle, the vehicle battery is discharged to assist in starting the vehicle, providing an automatic start mode.

[0012] As a further solution of this utility model, the farad supercapacitor starting power supply with battery charging function comprises: A manual mode switch is provided, and when the vehicle battery is seriously short of power and unable to start the vehicle, the switch is operated to transition the main control circuit board to a manual control state, and the manual start mode is forcibly controlled so that the farad supercapacitor pack discharges a high current to the vehicle battery to start the vehicle.

[0013] As a further solution of this utility model, the farad supercapacitor starting power supply with battery charging function comprises: When the vehicle battery is seriously low on power or completely discharged, the USB-C charging port is externally connected to a mobile power bank, and the main control circuit board and switching circuit charge the vehicle battery with the power of the mobile power bank. When the voltage of the vehicle battery rebounds to a level that allows starting, the vehicle can be started directly. This is the dead battery start mode.

[0014] Another solution of this utility model is that in the dead battery start mode, when the capacity of the externally connected mobile power bank is insufficient to directly start the vehicle, after the vehicle battery is fully charged, the externally connected mobile power bank is disconnected, and the system switches back to the mode in which the vehicle battery charges the farad supercapacitor pack, and finally, the vehicle battery and the farad supercapacitor pack jointly provide power in 2-in-1 mode to start the vehicle. [Effects of the Invention]

[0015] Compared with the prior art, the farad supercapacitor starting power supply with battery charging function proposed in this utility model has the following beneficial effects:

[0016] In this utility model, the battery charging function is integrated into the supercapacitor starting power supply, which can quickly fully charge the supercapacitor and assist in igniting vehicles with insufficient power. In extreme usage scenarios, when the starting power supply is insufficient to start the vehicle urgently, it can be connected to an external mobile power bank to charge the battery, and the vehicle can be started after the battery has recovered a certain amount of power, thereby realizing the emergency starting function in extreme scenarios for the vehicle. The MCU-controlled switching circuit supports three modes: NMOS, PMOS, or relay. When an external charging source and a vehicle battery are present at the same time, it can automatically start the charging mode and switch the output of the charging source to the supercapacitor pack or the battery, solving the limitations of the single function of conventional products and compared with the starting power supply of a lithium battery. All of these are suitable for extreme temperatures and have no hidden dangers or risks of swelling or spontaneous combustion. The switching circuit ensures current safety when starting ultra-large displacement vehicles. The supercapacitor can be connected to a battery that is running out of power and can be fully charged without waiting for rescue. When the battery is seriously low on power, a long press of the button will activate manual starting mode. When the battery of an ultra-large displacement vehicle is completely discharged, it can be connected to a mobile power bank externally to charge it. After charging, it can start directly or use 2-in-1 starting. The multi-mode battery discharge makes it suitable for different power shortage scenarios. It has significant beneficial effects in terms of safety, reliability, service life, application range, adaptability to working environments, and starting efficiency, meeting the market demand for an efficient, safe, and multi-functional emergency starting power source.

[0030] The Farad supercapacitor starting power supply of this embodiment can be used as an emergency starting power supply for automobiles using 12V batteries that cannot be ignited after a power shortage, and can also be used for motorcycles, agricultural vehicles, motorboats, etc., and can be used for any vehicle using a 12V battery, regardless of whether it is a gasoline or diesel vehicle.

By adding the function of charging lead-acid batteries, this utility model is the first to be a starting power supply with 2-in-1 function that combines emergency starting power and battery charging, whether the starting power supply uses a lithium battery or a Farad supercapacitor. The starting power supply of this utility model can not only independently charge the batteries of night market stalls / construction machinery, but also, in extreme situations, such as in cold weather, when the battery of an ultra-large displacement vehicle is severely short of power and the vehicle cannot be started and the starting power supply cannot ignite, it can be connected to a mobile power bank externally via a USB interface and use the battery charging function of this utility model to charge the vehicle's battery that is severely short of power. After the vehicle battery is charged to a certain level, the vehicle can be started normally, or can start the vehicle together with the starting power supply.

[0031] In this embodiment, the Farad supercapacitor starting power supply supports three switching working modes: automatic starting, manual starting and dead battery starting.

[0032] As shown in Figure 3, the farad supercapacitor starting power supply with battery charging function is: When the alligator clip output interface 10 is connected to a vehicle battery 3 that is running low on power, the remaining power of the vehicle battery 3 is used to reverse charge the farad supercapacitor pack 4, and after charging is complete, when the user ignites the vehicle, the vehicle battery 3 is discharged to assist in starting the vehicle, providing an automatic start mode.

[0033] As shown in Figure 4, the farad supercapacitor starting power supply with battery charging function is: A manual mode switch 8 is provided, and when the vehicle battery 3 is seriously short of power and unable to start the vehicle, the switch is operated to transition the main control circuit board 5 to a manual control state, and the Farad supercapacitor pack 4 is forcibly controlled to discharge a high current to the vehicle battery 3 to start the vehicle, thereby providing a manual start mode.

[0034] In manual start mode, if the automatic start mode is unable to start the vehicle, the vehicle battery may be seriously low on power and manual mode must be used.

[0035] As shown in Figure 5, the farad supercapacitor starting power supply with battery charging function is: When the vehicle battery 3 is seriously low on power or completely discharged, the USB-C charging port 7 is externally connected to the mobile power bank 11, and the main control circuit board 5 and the switching circuit charge the vehicle battery 3 with the power of the mobile power bank 11. When the voltage of the vehicle battery 3 rebounds to a level that allows starting, the vehicle can be started directly.

[0036] In the dead battery start mode, it is recommended to use a mobile power bank with a capacity of 20,000 mAh or more. When the capacity of the externally connected mobile power bank 11 is insufficient to directly start the vehicle, after charging of the vehicle battery 3 is completed, the externally connected mobile power bank 11 is disconnected, and the system switches back to the mode in which the vehicle battery 3 charges the farad supercapacitor pack 4, and finally, the vehicle battery 3 and the farad supercapacitor pack 4 jointly provide power in 2-in-1 mode to start the vehicle.

[0037] As shown in Figures 6 to 9, the switching circuit supports three switch types: NMOS, PMOS, and relay. When performing automatic start-up, manual start-up, and dead-battery start-up, under the control of the MCU control circuit on the main control circuit board 5, an external charging source is connected to the input connection point (CHA_OUT) of the switching circuit via a charging DC-DC circuit, and is connected to the farad capacitor charging switching circuit and the battery charging switching circuit in the switching circuit. The output side of the farad capacitor charging switching circuit is connected to the farad capacitor pack, i.e., the farad supercapacitor pack installed in the starting power supply, and is connected to the alligator clip positive terminal by a MOS output ignition circuit. The output side of the battery charging switching circuit is connected to the alligator clip positive terminal.

[0038] As shown in Figures 6 to 9, the MCU control circuit of the main control circuit board 5 detects the status of the external charging source and the vehicle battery 3, and sends a control signal to control the switching circuit. Through the control of the control signal, the MCU control circuit controls the switching circuit to switch the power output connection point of the switching circuit to the Farad supercapacitor pack or the vehicle battery. NMOS, PMOS, and relay are used as switching switches, respectively, and the NMOS channel switching circuit, PMOS channel switching circuit, and relay channel switching circuit of the switching circuit are used to switch between three working modes: automatic start, manual start, and dead battery start.

[0039] In this utility model, the supercapacitor starting power supply 1 is integrated with a battery charging function, which can quickly fully charge the supercapacitor, assist in ignition of a vehicle with insufficient power, charge the lead-acid battery independently, or connect to an external mobile power bank 11 to provide emergency starting for a vehicle battery 3 with a severe power shortage, thereby realizing emergency starting functions in extreme vehicle scenarios. The MCU-controlled switching circuit supports three modes: NMOS, PMOS, or relay. When an external charging source and a vehicle battery 3 are present at the same time, it can automatically start charging mode and switch the output of the charging source to the supercapacitor pack or the battery, solving the limitations of the single function of conventional products and being more adaptable to extreme temperatures than a lithium battery starting power supply. There are no hidden dangers or risks of swelling or spontaneous combustion, and the switching circuit ensures current safety when starting ultra-large displacement vehicles. The supercapacitor can be fully charged by simply connecting it to the battery when it is running out of power, without having to wait for help. When the battery is seriously low on power, a long press of the button will activate manual starting mode. When the battery of an ultra-large displacement vehicle is completely discharged, it will be connected to the mobile power bank 11 from the outside to charge, and after charging, it can be started directly or 2-in-1 started. The multi-mode battery discharge is suitable for different power shortage scenarios, and has significant beneficial effects in terms of safety, reliability, service life, application range, adaptability to working environments, and starting efficiency, meeting the market demand for an efficient, safe, and multi-functional emergency starting power source.
