This helps ensure the charging and discharging device's electric starting function enables the motorcycle to start electrically and meets the needs of connecting external electrical devices such as mobile phones, dashcams, or spotlights. Furthermore, the charging and discharging device also features a second conductive wire. One end of the second conductive wire is connected to the external structure, and the other end is connected to the battery. This ensures that the circuit between the battery and the external structure remains connected even when the ignition switch is off, allowing the user to directly connect an external power source to charge the battery.

[0032] Existing motorcycle battery charging methods typically involve users notifying repair shops for on-site service, transporting the motorcycle to the shop for charging, or removing the battery and transporting it to the repair shop for charging. These methods are time-consuming and labor-intensive, negatively impacting the user experience. This application provides a charging and discharging device and motorcycle that eliminates the need to notify repair shops for on-site service, transport the motorcycle to the shop for charging, or remove the battery and transport it to the repair shop for charging. The charging and discharging method is simple and reliable, saving repair time and costs, improving the user experience, and facilitating application and promotion.

[0033] One embodiment of this application provides a motorcycle that includes a charging and discharging device 1.

[0034] Specifically, in combination Figure 2 As shown, the charging and discharging device 1 can be connected to, but is not limited to, the starting system 2 of the motorcycle for starting the motorcycle engine. Additionally, the charging and discharging device 1 can also be connected to, but is not limited to, the motorcycle's ignition system, lighting system, signal system, charging system, and other electronic devices such as the dashboard or anti-theft system.

[0035] This application makes the following improvements to the above-mentioned charging and discharging device 1.

[0036] For details, please refer to the appendix. Figure 1 One embodiment of this application provides a charging and discharging device 1, which may include a battery 100, a first conductive line 200, an ignition switch 300, an external structure 400, and a second conductive line 500. The ignition switch 300 is connected in series with the battery 100 and electrically conductive through the first conductive line 200. One end of the external structure 400 is connected to the first conductive line 200, and the other end of the external structure 400 is used to connect an external electrical device. One end of the second conductive line 500 is connected to the external structure 400, and the other end of the second conductive line 500 is connected to the battery 100.

[0037] The ignition switch 300 of the charging and discharging device 1 is connected in series with the battery 100 through the first conductive line 200 and electrically conductive. One end of the external structure 400 is connected to the first conductive line 200, and the other end of the external structure 400 is used to connect external electrical devices. This helps to ensure the electric starting function of the motorcycle and meet the needs of external electrical devices of the motorcycle. In addition, the above-mentioned charging and discharging device 1 is also provided with a second conductive line 500. One end of the second conductive line 500 is connected to the external structure 400, and the other end of the second conductive line 500 is connected to the battery 100. This helps to achieve circuit connection between the battery 100 and the external structure 400 when the ignition switch 300 is off. Then, the user can directly connect an external power source through the external structure 400 to charge the battery 100. This charging method does not require notifying the repair shop for on-site service, taking a motorcycle to the shop to charge the battery 100, or removing the battery 100 to the repair shop for charging. It is simple and reliable, saves repair time and costs, improves the user's vehicle experience, and is easy to apply and promote.

[0038] It is worth noting that the external structure 400 is connected to the first conductive line 200, thus associating the conduction of the external structure 400 with the ignition switch 300. Specifically, the battery 100 has a charging mode and a discharging mode. When the ignition switch 300 is on, the battery 100 automatically switches to the discharging mode. In the discharging mode, only the circuit "battery 100 - ignition switch 300 - external structure 400 - battery 100" is active, allowing the battery 100 to provide power to external components through the external structure 400. When the ignition switch 300 is off, the battery 100 automatically switches to the charging mode. Since the ignition switch 300 is off, other components on the motorcycle (such as the components of the starting system) are de-energized. In this mode, only the battery 100 is electrically connected to the external structure 400 through the second conductive line 500, allowing the user to directly connect to an external power source through the external structure 400. This helps improve charging safety and efficiency.

[0039] For example, the external structure 400 can be implemented as a USB charger, but is not limited to. The external structure 400 can make full use of the power role confirmation function (Source or Sink) of the CC line in the protocol chip that supports the Type-C interface. Then, the external structure 400 can determine whether the battery 100 is in charging mode or discharging mode according to the external power supply or other electrical devices connected in the usage scenario, and adapt to the switching of the usage scenario of the battery 100.

[0040] Optionally, the charging power of the battery 100 can be set to greater than or equal to 18 watts. For example, the charging power of the battery 100 can be set to 18 watts, 19 watts, or 20 watts, etc.

[0041] Optionally, the battery 100 has a control module (not shown). When the ignition switch 300 is turned on, the control module controls the battery 100 to switch to discharge mode. When the ignition switch 300 is turned off, the control module controls the battery 100 to switch to charging mode. This can improve the stability of the battery 100 when switching between charging and discharging modes, protect the structure of the battery 100, and improve the service life of the battery 100.

[0042] Optionally, the charging / discharging device 1 further includes a wiring structure 600, which is disposed on the first conductive line 200. One end of the external structure 400 and one end of the second conductive line 500 are both connected to the wiring structure 600. Thus, the wiring structure 600 helps to connect both the wiring structure 600 and the second conductive line 500 to the first conductive line 200, thereby improving structural compactness.

[0043] Specifically, the wiring structure 600 can be implemented as a T-type wiring, which is simple and reliable.

[0044] Optionally, combined Figure 2 As shown, the second conductor 500 is configured to conduct in one direction, so that the current flows unidirectionally in the direction of flowing into the battery 100. This ensures that in the discharge mode, the current flows only through the line from the battery 100 to the ignition switch 300 to the external structure 400 and not through the second conductor 500. Only in the charging mode of the battery 100, when the external structure 400 is connected to an external power source, does the current flow unidirectionally in the direction of flowing into the battery 100 through the second conductor 500, so as to charge the battery 100.

[0045] Specifically, the second conductive line 500 can, but is not limited to, use a specific electronic component 510 to achieve unidirectional current flow, that is, the current can only pass in one direction and is blocked in the reverse direction. More specifically, the aforementioned electronic component 510 can, but is not limited to, be implemented as a diode or a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), etc. It should be noted that any scheme that can achieve unidirectional current conduction along the second conductive line 500 in the direction of flowing into the battery 100 falls within the protection scope of this application, and will not be elaborated further here.

[0046] Optionally, the external structure 400 may include a third conductive line 410 and an external connector 420. One end of the third conductive line 410 is connected to the first conductive line 200, and the other end of the third conductive line 410 is connected to the external connector 420, which is used to connect external electrical components. In this way, the user can adjust the length of the third conductive line 410 to position the external connector 420 in a preset location, thereby optimizing the arrangement of external components and improving the user experience.

[0047] Optionally, the external connector 420 may be equipped with a detection module (not shown). The detection module is used to detect the power level of the battery 100, thereby enabling the monitoring function of the battery 100 power level and timely reminding the user to charge the battery 100. This prevents the battery 100 from failing to start due to insufficient monitoring function, thus improving the user's vehicle experience.

[0048] Optionally, the external connector 420 is also provided with an alarm structure (not shown), which is connected to the detection module and is used to issue an alarm signal based on the power level of the battery 100.

[0049] Optionally, the alarm structure can be implemented as an audible alarm or a warning light alarm, etc. In this way, the low battery alarm function of the battery 100 and the function of external components of the battery 100 are integrated into the external connector 420, which improves the compactness of the structure and makes it easier for users to find the alarm structure when using external components, thus improving the warning effect.

[0050] Optionally, the battery 100 may be equipped with a charging capacity threshold. When the battery 100 reaches the charging capacity threshold, the external structure 400 is automatically disconnected. This helps to protect the structure of the battery 100, improve the service life of the battery 100, and enhance charging safety.

[0051] It should be noted that the battery 100 of this application is also connected to the motorcycle's charging system. The charging system can replenish the battery 100's charge through the engine's power output after the motorcycle is electrically started. However, the external charging structure 400 of the charging and discharging device 1 of this application is generally used as an emergency measure when the battery 100's charge is insufficient to start the motorcycle, and is not suitable for fully charging the battery 100 through an external charging power source. Therefore, according to the above embodiments of this application, the battery 100 has a charging capacity threshold. When the battery 100 reaches the charging capacity threshold, the external structure 400 automatically disconnects. This helps protect the battery 100 structure, improves the battery 100's lifespan, and enhances charging safety.

[0052] Optionally, the battery 100 includes a positive terminal and a negative terminal. The first conductive line 200 may include a positive wire and a negative wire. The ignition switch 300 is connected to the positive terminal via the positive wire and to the negative terminal via the negative wire. One end of the external structure 400 is connected to the negative wire. One end of the second conductive line 500 is connected to the external structure 400, and the other end of the second conductive line 500 is connected to the positive terminal. This ensures the accuracy of the circuit connection and ensures that when the ignition switch 300 is off and the external structure 400 is connected to an external charging power supply, the current from the charging power supply can flow into the positive terminal of the battery 100 through the second conductive line 500 to charge the battery 100.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
