Technical Field

[0002] Currently, most motorcycle power supplies on the market use lead-acid batteries as their primary energy source. While lead-acid batteries offer the advantage of low cost, they also have several significant drawbacks, such as high self-discharge rate, short cycle life, low energy density, bulky size, and environmental pollution. With the development of lithium battery technology, some products have begun to adopt lithium batteries as an alternative to improve energy density and cycle life.

[0003] However, existing lithium battery power products have relatively limited functionality, mostly only meeting the basic need for vehicle starting and lacking consideration for diverse user scenarios. Furthermore, to achieve multi-functional expansion, existing products typically require additional openings in the casing or the addition of external interfaces, which not only increases product complexity and manufacturing costs but also impacts the overall product design and user experience.

[0004] Therefore, there is an urgent need in this field for a power supply with high integration, rich functionality, and strong intelligence, which can meet the user's needs in multiple scenarios while ensuring basic startup functions. Utility Model Content

[0026] The two ends of the load R1 are connected to the positive output terminal P+ and the negative output terminal P-, respectively. The load R1 is connected to the positive output terminal P+ through a trigger switch K1.

[0027] In this embodiment, the trigger switch K1 is a push-button switch.

[0032] More specifically, the trigger circuit also includes a first Zener diode ZD6, the negative terminal of which is connected to the gate of the first MOSFET Q28, and the positive terminal is connected to the negative output terminal P-.

[0033] Example 2 One implementation method of the starting power supply system of this utility model is as follows: Figures 1 to 5 As shown, the main technical solution of this embodiment is basically the same as that of Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is as follows: The wake-up module also includes a charging wake-up circuit; The charging wake-up circuit includes a first transistor Q8 and a second transistor Q13. The base of the first transistor Q8 is connected to the positive output terminal B+ through resistors R40 and R35.

[0034] Specifically, the base of the first transistor Q8 is grounded through the first diode D4, and the emitter is connected to the negative output terminal P- through the second diode D6.

[0035] More specifically, the first transistor is an NPN transistor; the second transistor is a PNP transistor.

[0036] Example 3 One implementation method of the starting power supply system of this utility model is as follows: Figures 1 to 5As shown, the main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2. Features not explained in this embodiment adopt the explanations in Embodiment 1 or Embodiment 2, and will not be repeated here. The difference between this embodiment and Embodiment 1 or Embodiment 2 is: It also includes an internal power supply module; the input terminal of the internal power supply module is connected to the positive terminal B+ of the battery, and the output terminal supplies power to the control module and the output module respectively, providing operating voltage for the control module and the output module. Specifically, the base and collector of the first transistor Q8, and the base and emitter of the second transistor Q13 are connected to the output terminal (+3V3) of the internal power supply module; the internal power supply module also has a signal feedback terminal, which is connected to the second transistor Q13. The drain of the second MOSFET Q19 is connected to the signal feedback terminal of the internal power supply module.

[0037] According to another aspect of the present invention, a mobile vehicle is provided that employs the aforementioned starting power system.

[0038] The specific working principle of this utility model is as follows: When the battery level is greater than 30%, it is in standby mode. The main control MCU controls the third MOSFET D1 and the fourth MOSFET C1 to turn on normally, and the main control MCU controls POWSAAVE to output a high level. At this time, the battery normally supplies power to the internal power supply module and the external module.

[0039] When the battery level is between 10% and 30%, it is in low-power mode. The main control MCU controls the third MOSFET D1 to turn off and the fourth MOSFET C1 to turn on. At this time, the system can charge but cannot discharge. If the customer presses the button K1 on the external module at this time, connecting the positive output terminal P+ and the negative output terminal P-, a voltage surge will be applied to the negative output terminal P-. When the surge voltage exceeds the breakdown voltage of the Zener diode ZD6, the first MOSFET Q28 will be triggered to turn on, charging the first capacitor C34. During the charging process, the second MOSFET Q19 will be turned on, and the voltage level signal K_DET will change. After the main control MCU recognizes the voltage change in the voltage level signal K_DET, it turns on the third MOSFET D1 to provide emergency power to the battery. After the first capacitor C34 is fully charged, the second MOSFET Q19 will turn off. Therefore, even if the user accidentally presses and holds the button for a long time, the product will not be continuously woken up, thus effectively saving energy and preventing further battery depletion while ensuring normal user operation.

[0040] When the battery level is below 10%, the system enters sleep mode. The main control MCU controls both the third MOSFET D1 and the fourth MOSFET C1 to be turned off, and POWSAAVE outputs a low level. At this time, the system is in a state where it cannot charge or discharge. If the customer connects the charger at this time, since the positive output terminal P+, the battery positive terminal B+, and the charger positive terminal are connected together, and the charger's output voltage is higher than the product voltage, the charger's voltage will flow through the battery B+, the internal power supply module, resistor R35, and resistor R40, thereby triggering the first transistor Q8 to turn on. Then, the current flows through resistor R51 and resistor R40, triggering the second transistor Q13 to turn on, thus causing a voltage change in the level signal C_DET. This allows the internal power supply module to resume powering the main control MCU. At the same time, the main control MCU can be woken up by the level signal C_DET.

[0041] In summary, the above methods can adapt to different power levels and scenarios, ensuring that users can effectively save energy and avoid further battery depletion under normal usage conditions.
