[0002] Electric motorcycles, also known as electric vehicles, are electrically powered vehicles. Electric vehicles are categorized as AC and DC. Generally speaking, electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through components such as controllers and motors, and controlling the current to change speed. Electric vehicles are a convenient means of short-distance transportation and have become a commonplace in everyday life. There are a wide variety of electric bicycle brands on the market. High-quality electric vehicles offer stable operation, long battery life, and a safe and comfortable ride.
[0003] Currently, electric vehicles generally have instrument panels, whose main function is to display information such as the remaining battery power and the real-time speed of the vehicle. In addition to needing to know information such as the remaining battery power and the real-time speed of the vehicle, users often need to use the navigation function when using electric vehicles. However, electric motorcycle instrument panels on the market generally do not have this function. If you want to add a navigation function to the electric motorcycle instrument panel, you must also add a SIM card for networking, which greatly increases the production cost of the electric motorcycle instrument panel.
