Description

Technical Field

[0001] This utility model relates to the technical field of automotive emergency starting equipment, specifically to a supercapacitor starting power supply with battery charging capability. Background Technology

[0002] Existing emergency jump starters primarily use lithium battery technology, which has the following drawbacks: they require regular charging and maintenance (long-term neglect of charging can lead to permanent damage to the lithium battery), they cannot be stored for extended periods in the extreme temperature environments inside a vehicle (high temperatures inside the vehicle can cause bulging or spontaneous combustion), they cannot be used in extreme temperature environments (supercapacitors can operate in environments ranging from -40℃ to 70℃), and their lifespan is relatively short (supercapacitors have a lifespan of over 10 years). Furthermore, commercially available products only provide a single emergency starting function and cannot be used to start or assist starting the vehicle after charging it with an external power source when the battery is severely depleted. For example, in cold weather, when the battery of a high-displacement vehicle is completely dead, traditional lithium battery jump starters cannot function due to the extremely low temperature, requiring roadside assistance. The document mentions that there is currently no two-in-one product combining a supercapacitor and battery charging functions.

[0003] Therefore, there is an urgent need for a new type of starter power supply that is safe, reliable, maintenance-free, and integrates charging functionality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a supercapacitor-based starting power supply with battery charging. It adopts supercapacitor technology and combines it with an intelligent switching circuit to realize the dual functions of emergency vehicle starting and battery charging. It aims to solve the problems of existing emergency starting power supplies, such as safety hazards (e.g., lithium battery spontaneous combustion), high maintenance costs, inability to adapt to extreme temperature environments, and inability to assist in starting the vehicle through charging when the battery is severely depleted.

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

[0006] To achieve the above objectives, this utility model provides a supercapacitor-based startup power supply with battery charging capability, comprising a startup power supply housing, a supercapacitor group disposed within the startup 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 interface for connecting to an external charging source, a switching circuit for power path switching management, and an MCU control circuit.

[0007] The alligator clip output interface connects to the vehicle battery via an alligator clip; the switching circuit includes a capacitor bank charging switching circuit and a battery charging switching circuit; the capacitor bank charging switching circuit is electrically connected to the supercapacitor bank and the USB-C charging interface connected to the external charging source, and the battery charging switching circuit is electrically connected to the alligator clip output interface and the USB-C charging interface connected to the external charging source; the MCU control circuit is electrically connected to the control terminal 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 control signals to the power path management switching circuit; when the USB-C charging interface is connected to the external charging source and the alligator clip output interface is connected to a depleted vehicle battery, the MCU control circuit controls the switching circuit to be configured in battery charging mode, guiding the charging current from the external charging source to the vehicle battery to charge the vehicle battery.

[0008] As a further embodiment of this utility model, the switching circuit also includes a capacitor bank charging switching circuit and a battery charging switching circuit. The power input connection point of the switching circuit is the USB-C charging interface of an external charging source, and the power output connection point of the switching circuit is controlled by the MCU control circuit to switch the switching circuit to the supercapacitor bank or the vehicle battery.

[0009] As a further embodiment of this invention, the MCU control circuit is used to detect the status of the starting power supply and the vehicle battery, and send control signals to control the switching circuit.

[0010] As a further embodiment of this utility model, the switching circuit can switch in at least one of NMOS, PMOS or relay switches, supporting three switch types: NMOS, PMOS or relay.

[0011] As a further embodiment of this invention, the supercapacitor starting power supply supports three operating modes: automatic start, manual start, and battery charging start.

[0012] As a further embodiment of this invention, the supercapacitor-based starting power supply with battery charging has an automatic start-up mode:

[0013] When the alligator clip output interface is connected to a depleted vehicle battery, the remaining power of the vehicle battery is used to charge the supercapacitor bank in reverse. After charging is completed, the vehicle battery is automatically discharged to assist in starting the vehicle when the user performs the vehicle ignition operation.

[0014] As a further embodiment of this invention, the supercapacitor-based starting power supply with battery charging has a manual start mode:

[0015] A manual mode switch is provided, which is used to activate the main control circuit board to enter manual control mode when the vehicle battery is severely depleted and the vehicle cannot be started. This forces the supercapacitor bank to discharge a large current to the vehicle battery in order to start the vehicle.

[0016] As a further embodiment of this invention, the supercapacitor starting power supply with battery charging has a battery-charged starting mode:

[0017] When the vehicle battery is severely depleted or completely dead, an external power source can be connected through the USB-C charging port. The main control circuit board and switching circuit will then charge the vehicle battery with the power from the external power source. Once the vehicle battery voltage has recovered to the allowable starting level, the vehicle can be started directly.

[0018] As a further embodiment of this utility model, in the battery charging and starting mode, if the capacity of the external mobile power supply is insufficient to directly start the vehicle, after the vehicle battery is fully charged, the external mobile power supply is disconnected, and the system switches back to the mode where the vehicle battery charges the supercapacitor bank. Finally, the vehicle battery and the supercapacitor bank work together in a two-in-one mode to provide power to start the vehicle.

[0019] Compared with existing technologies, the supercapacitor starting power supply with battery charging proposed in this utility model has the following advantages:

[0020] This invention integrates battery charging functionality into a supercapacitor starting power supply, enabling rapid charging of the supercapacitor and assisting in starting vehicles with depleted batteries. In extreme scenarios where the starting power supply is insufficient for emergency vehicle starting, an external power source can charge the battery. Once the battery has regained some charge, the vehicle can be started, achieving emergency starting functionality in extreme situations. Furthermore, the MCU-controlled switching circuit supports NMOS, PMOS, and relay modes. When both an external charging source and the vehicle battery are present, the charging mode is automatically activated, and the charging source output can be switched to either the supercapacitor bank or the battery. This overcomes the limitations of traditional single-function products and offers significant advantages over lithium battery starting power supplies. This power supply can withstand extreme temperatures without the risk of bulging or spontaneous combustion. The switching circuit ensures safe current during the starting of ultra-large displacement vehicles. The supercapacitor can be fully charged simply by connecting to a depleted battery, eliminating the need to wait for roadside assistance. When the battery is severely depleted, a long press of the button triggers a manual start mode. When the battery of an ultra-large displacement vehicle is completely dead, it can be charged by an external power bank. After charging, it can be started directly or in a two-in-one start mode. Multiple charging modes adapt to different power depletion scenarios. It has significant benefits in terms of safety, reliability, service life, applicable scope, adaptability to working environment, and starting efficiency, meeting the market's demand for efficient, safe, and multifunctional emergency jump starters.

[0038] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] See Figures 1 to 9 As shown, an embodiment of this utility model provides a supercapacitor starting power supply with battery charging, including a starting power supply housing 1, a supercapacitor group 4 disposed in the starting power supply housing 1, a main control circuit board 5, and an alligator clip output interface 10; the main control circuit board 5 also includes a USB-C charging interface 7 for connecting to an external charging source, a switching circuit for power path switching management, and an MCU control circuit. The alligator clip output interface 10 is connected to the vehicle battery 3 via the alligator clip 2; the switching circuit includes a capacitor bank charging switching circuit and a battery charging switching circuit; the capacitor bank charging switching circuit is electrically connected to the supercapacitor bank 4 and the USB-C charging interface 7 connected to the external charging source, and the battery charging switching circuit is electrically connected to the alligator clip output interface 10 and the USB-C charging interface 7 connected to the external charging source; the MCU control circuit is electrically connected to the control terminal of the switching circuit; the MCU control circuit is configured to monitor the status of the external charging source and the vehicle battery 3, and output control signals to the power path management switching circuit; when the USB-C charging interface 7 is connected to the external charging source and the alligator clip output interface 10 is connected to the depleted vehicle battery 3, the MCU control circuit controls the switching circuit to be configured in battery charging mode, guiding the charging current from the external charging source to the vehicle battery 3 to charge the vehicle battery 3.

[0041] See Figure 1 and Figure 2 As shown, in the battery-charged supercapacitor starting power supply, the alligator clip output interface 10 of the starting power supply housing 1 is connected to the vehicle battery 3 via alligator clip 2. The starting power supply housing 1 houses a supercapacitor group 4 and a main control circuit board 5 connected to the supercapacitor group 4. Optional features on the side of the starting power supply housing 1 include a charging interface, an alligator clip output interface 10, a display screen 9, and a manual mode switch 8, all connected to the main control circuit board 5. The charging interface on the side of the starting power supply housing 1 includes a DC charging interface 6 and a USB-C charging interface 7. The manual mode switch 8 is a power switch connected to the main control circuit board 5 for controlling charging and discharging. The USB-C charging port 7 is used to connect an external power bank 11. The alligator clip output port 10 of the power bank housing 1 is equipped with a high-current output female connector (such as an EC5 female connector). The wires of the alligator clip 2 are equipped with matching male connectors (such as EC5 male connectors). The female connector and male connector are not limited to EC5, but can also be any other connector that can meet this current requirement, such as XT90, Anderson Powerpole and other mainstream high-current interfaces.

[0042] In this embodiment, the switching circuit further includes a capacitor bank charging switching circuit and a battery charging switching circuit. The power input connection point of the battery charging switching circuit is the USB-C interface 7 of the external charging power supply, and the power output connection point is the alligator clip output interface 10 of the power supply. When the USB-C charging interface 7 is connected to an external charging power supply and the alligator clip output interface 10 is connected to a depleted vehicle battery 3, the MCU control circuit controls the switching circuit to be configured in battery charging mode, directing the charging current from the external charging power supply to the vehicle battery to charge it.

[0043] In this embodiment, the MCU control circuit is used to detect the status of the starting power supply and the vehicle battery 3, and send control signals to control the switching circuit. The switching circuit uses at least one of NMOS, PMOS, or relay switches, supporting three switch types: NMOS, PMOS, or relay.

[0044] This embodiment of the farad supercapacitor starting power supply can be used as an emergency starting power supply for vehicles that cannot be started after a 12V battery has run out of power. It is also applicable to motorcycles, agricultural vehicles, motorboats, etc., and is suitable for both gasoline and diesel vehicles that use 12V batteries. Designed using farad supercapacitor technology, compared to lithium battery starting power supplies, it can be stored in the vehicle for many years without the need for regular charging and maintenance. It is safe and reliable and will not bulge or spontaneously combust; its service life exceeds ten years; it can operate in extreme temperature environments from -40℃ to 70℃; and it has the characteristic of being ready to use immediately after charging, fully charging in 3 minutes for emergency vehicle starting without waiting for roadside assistance. This invention adds the function of charging lead-acid batteries. Whether using a lithium battery or a supercapacitor, this is the first starter power supply to combine emergency starter power and battery charging functions. Besides independently charging batteries used in night market stalls or construction equipment, this starter power supply can also be used in extreme situations, such as when a large-displacement vehicle's battery is severely depleted in cold weather and the starter power supply fails to start the vehicle. By connecting an external power bank via USB and using the battery charging function of this invention, the severely depleted vehicle battery can be charged. Once the battery is charged to a certain level, the vehicle can be started normally, or it can be used in conjunction with the starter power supply to start the vehicle.

[0045] In this embodiment, the supercapacitor starting power supply supports three operating modes: automatic start, manual start, and battery charging start.

[0046] like Figure 3 As shown, the supercapacitor-based starting power supply with battery charging has an automatic start-up mode:

[0047] When the alligator clip output interface 10 is connected to the depleted vehicle battery 3, the remaining power of the vehicle battery 3 is used to charge the supercapacitor group 4 in reverse. After charging is completed, the vehicle battery 3 is automatically discharged to assist in starting the vehicle when the user performs the vehicle ignition operation.

[0048] like Figure 4 As shown, the supercapacitor-based starting power supply with battery charging has a manual start mode:

[0049] A manual mode switch 8 is provided, which is used to activate the main control circuit board 5 to enter manual control mode when the vehicle battery 3 is severely depleted and cannot start the vehicle. This forces the supercapacitor group 4 to discharge a large current to the vehicle battery 3 in order to start the vehicle.

[0050] If the vehicle cannot be started in manual start mode, it may be due to a severely depleted battery, requiring the use of manual mode.

[0051] like Figure 5 As shown, the supercapacitor-based starting power supply with battery charging is characterized by having a battery-charging starting mode:

[0052] When the vehicle battery 3 is severely depleted or completely out of power, a mobile power supply 11 is connected to the USB-C charging port 7, and the main control circuit board 5 and the switching circuit charge the vehicle battery 3 with the power of the mobile power supply 11. After the voltage of the vehicle battery 3 rises back to the allowable starting level, the vehicle can be started directly.

[0053] In the battery charging start mode, it is recommended to use a power bank with a capacity of 20000mAh or above. If the capacity of the external power bank 11 is insufficient to start the vehicle directly, after charging the vehicle battery 3, disconnect the external power bank 11 to switch the system back to the mode in which the vehicle battery 3 charges the supercapacitor group 4. Finally, the vehicle battery 3 and the supercapacitor group 4 provide power to start the vehicle in a two-in-one mode.

[0054] like Figures 6 to 9 As shown, the switching circuit supports three switch types: NMOS, PMOS, or relay. When performing automatic start, manual start, and battery charging start, under the control of the MCU control circuit of the main control circuit board 5, the external charging source is connected to the input connection point (CHA_OUT) of the switching circuit through the charging DC-DC circuit. It is connected to the supercapacitor charging switching circuit and the battery charging switching circuit in the switching circuit. The output terminal of the supercapacitor charging switching circuit is connected to the supercapacitor group, that is, the supercapacitor group set in the starting power supply, and is connected to the positive terminal of the alligator clip by the MOS output ignition circuit; the output terminal of the battery charging switching circuit is connected to the positive terminal of the alligator clip.

[0055] See Figures 6 to 9 As shown, 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 control signals to control the switching circuit. Through the control signal, the power output connection point of the switching circuit is controlled by the MCU control circuit to switch the switching circuit to the supercapacitor bank or the vehicle battery. NMOS, PMOS and relay are used as switching switches respectively. The switching circuit uses the NMOS channel switching circuit, PMOS channel switching circuit and relay channel switching circuit to realize the switching of three working modes: automatic start, manual start and battery charging start.

[0056] This invention integrates battery charging functionality into a supercapacitor starting power supply 1, enabling rapid charging of the supercapacitor to assist in starting a vehicle with a dead battery. It can also independently charge a lead-acid battery or, via an external power source 11, replenish the battery 3 of a severely depleted vehicle, providing emergency starting capability in extreme scenarios. Furthermore, based on an MCU-controlled switching circuit, it supports NMOS, PMOS, and relay modes. When an external charging source and the vehicle battery 3 are both present, the charging mode is automatically activated, and the charging source output can be switched to either the supercapacitor bank or the battery. This overcomes the limitations of traditional single-function products and, compared to a lithium battery starting power supply 1, can adapt to extreme conditions. With temperature-limited design, there is no risk of bulging or spontaneous combustion. The switching circuit ensures safe current during the start-up of ultra-large displacement vehicles. The supercapacitor can be fully charged simply by connecting to a depleted battery, eliminating the need to wait for roadside assistance. When the battery is severely depleted, a long press of the button triggers a manual start mode. When the battery of an ultra-large displacement vehicle is completely dead, it can be charged by an external power bank. After charging, it can be started directly or in a two-in-one start mode. Multiple charging modes adapt to different power depletion scenarios. It has significant benefits in terms of safety, reliability, service life, applicability, adaptability to working environment, and starting efficiency, meeting the market demand for an efficient, safe, and multifunctional emergency jump starter.
