[0037] See also Figure 1-Figure 2 The present invention discloses a fast charging circuit for a bicycle electronic transmission, which includes: an input connection module 10, a charging control module 20, a battery management module 30 and an output connection module 40. The input connection module 10 is used to receive an input power supply and convert the voltage of the input power supply into a stable input voltage. The charging control module 20 is used to monitor the charging state of the battery in real time and adjust the charging parameters according to the current state of the battery and preset parameters. The battery management module 30 is used to detect abnormal conditions of the battery during the charging process and take corresponding protective measures according to different abnormal conditions. The output connection module 40 is used to output current to the battery of the bicycle electronic transmission. The input connection module 10, the charging control module 20, the battery management module 30 and the output connection module 40 are electrically connected in sequence. The charging control module 20 includes a charging efficiency optimization unit, which includes a switching power supply circuit and a pulse charging circuit, and the output end of the switching power supply circuit is connected to the input end of the pulse charging circuit.

[0038] It should be noted that the circuit of the present invention integrates an input connection module 10, a charging control module 20, a battery management module 30 and an output connection module 40, and these modules are electrically connected in sequence to form a complete and efficient charging system. This design not only improves the integration and reliability of the circuit, but also makes the entire charging process more stable and safe. In the charging control module 20 of the present invention, a charging efficiency optimization unit is particularly provided, which includes a switching power supply circuit and a pulse charging circuit. The switching power supply circuit is responsible for converting the input voltage into a voltage suitable for charging, while the pulse charging circuit charges the battery through a pulse signal. This charging method can further improve the charging efficiency and shorten the charging time. At the same time, pulse charging also helps to reduce the polarization phenomenon inside the battery, and improve the charging acceptance and cycle life of the battery. Furthermore, the switching power supply technology and the pulse charging technology can accurately control the energy transfer during the charging process to ensure that the electrical energy is transmitted to the battery in the most efficient way. The switching power supply circuit includes a high-frequency switching device, a transformer and a rectifier circuit. The switching power supply technology is mainly used to improve the energy conversion efficiency and reduce the volume and weight of the charging system. It converts the input electrical energy into high-frequency pulse waves through high-frequency switching devices, and then converts it into direct current suitable for battery charging through transformers and rectifier circuits. This conversion method not only improves the utilization rate of energy, but also makes the charging system more compact and lightweight. The pulse charging technology focuses on the precise control of the charging process. By accurately adjusting the pulse width and frequency of the charging current, the technology can flexibly adjust the charging parameters according to the real-time status of the battery, thereby further improving the charging efficiency. In addition, the pulse charging technology can effectively reduce the polarization of the battery and effectively extend the service life of the battery.

[0039] The input power management module 10 provides a stable input voltage through a voltage stabilization and filtering circuit to ensure the stability of the input voltage during the charging process. In this embodiment, the main function of the input management module 10 is to receive electrical energy from an external power source and process it through a voltage stabilization and filtering circuit to ensure that a stable and reliable input voltage is provided to the entire charging system. Furthermore, the voltage stabilization technology used in this module can stabilize input voltages of different amplitudes within a certain range, thereby ensuring the smooth progress of the subsequent charging process. At the same time, in order to eliminate noise and interference in the external power supply, the module is also equipped with an efficient filtering circuit, which can accurately filter out high-frequency noise and stray interference signals to ensure the stability of the input voltage.

[0040] The charging control module 20 can adjust the charging current and voltage according to the current state of the battery (voltage, current, temperature, etc.), realize intelligent fast charging control, and automatically adjust the charging parameters to avoid overcharging, over-discharging or overheating. The charging control module 20 includes a DC-DC converter, which has an efficient voltage conversion function and can stably, quickly and accurately convert the voltage of the input power supply into a voltage and current suitable for the electronic transmission battery. At the same time, the stable output of the current is ensured. This efficient processing mechanism not only ensures the continuity and safety of the charging process, but also significantly reduces energy loss and improves charging efficiency. In this embodiment, the charging control module 20 also includes user-defined charging mode options. These different charging mode options constitute different charging strategies. Users can adjust the charging strategy according to their own needs. The charging control module 20 also includes an intelligent recognition unit. The intelligent recognition unit integrates the intelligent recognition function and can monitor and accurately grasp the charging state of the battery in real time. When the system detects that the battery charge is about to approach the preset upper limit, the module will automatically start the switching program to smoothly transition the current fast charging mode to a more gentle trickle charging mode. This sophisticated control method can not only effectively avoid damage to the battery caused by overcharging and extend the battery life, but also ensure that the battery is maintained in the best state during the charging process, thereby optimizing the overall charging efficiency. Furthermore, the charging control module 20 can also accurately identify and adapt to the charging needs of different types of batteries. It automatically adjusts the charging current and voltage corresponding to the battery of different models according to the real-time status and preset parameters of the battery of different models to ensure the best charging effect. At the same time, the module can also intelligently adjust the charging voltage according to the voltage characteristics and usage status of different models of batteries to ensure that the battery is charged within the optimal voltage range.

[0041] The battery management module 30 is used to detect abnormal conditions of the battery during the charging process. By accurately monitoring key indicators such as the battery voltage, current and temperature, the battery management module 30 can quickly identify and respond to abnormal conditions that may cause damage to the battery. If the battery temperature is too high or a short circuit is detected, the protection circuit can respond quickly and take corresponding protection measures to ensure that the battery is not damaged. This intelligent protection system can not only improve the service life of the battery, but also enhance the safety and stability of the entire charging process. It should be noted that the battery management module 30 further integrates a special battery protection circuit 31 to ensure the safety of the battery during the charging process and effectively avoid potential dangerous conditions such as overcharging, overheating or short circuit. The battery protection circuit 31 can quickly identify and respond to abnormal conditions that may cause damage to the battery by accurately monitoring key indicators such as the battery voltage, current and temperature. If the battery temperature is too high or a short circuit is detected, it can respond quickly and take corresponding protection measures to ensure that the battery is not damaged. This intelligent protection system can not only improve the service life of the battery, but also enhance the safety and stability of the entire charging process. Furthermore, the battery protection circuit 31 controls the on-off of the circuit through the PMOS circuit 311. The battery protection circuit 31 also includes a thermistor 312, and the thermistor 312 is electrically connected to the PMOS circuit.

[0042] Furthermore, the output connection module 40 is connected to a charging interface, which includes but is not limited to a TYPE-C interface, through which the battery can be directly connected.
