Many friends are very puzzled about the low-speed warning sound system for electric vehicles. Why install such a system on electric vehicles? Electric vehicles already have horns, but they also need to install a low-speed warning sound system, which shows that this system plays a different role than horns. When the speed of the electric vehicle is below 25 miles per hour, it emits a warning sound to remind pedestrians to avoid.

Compared to traditional fuel vehicles, electric vehicles are quieter during operation, especially when driving at low speeds. It is not an exaggeration to describe them as "elusive", but it is precisely because they are too quiet that pedestrians are less likely to notice vehicles nearby. In order to further protect travel safety, electric vehicles are equipped with an electric vehicle low-speed warning sound system. Whenever the speed is below 25 miles per hour, the vehicle's electric vehicle low-speed warning sound system will automatically emit a beeping sound to remind pedestrians.
But isn't using a horn enough? Many friends have told us that the horn often scares them, especially when they are close to the car, the sound of the horn is even more harsh. The low-speed warning sound system of electric vehicles is continuous and will not suddenly startle. When the crowd is dense, pedestrians can also perceive that the electric vehicle is nearby.
According to the "Technical Conditions for Motor Vehicle Operation Safety" GB7258 regulation, which was officially implemented on January 1, 2018, electric vehicles should be able to emit appropriate warning sounds to people outside the vehicle when the speed is below 20km/h after starting, and when the driver leaves pure electric vehicles or plug-in hybrid vehicles, if the vehicle drive system is still in "drivable mode", a clear signal device should be used to alert the driver. After cutting off the power supply, pure electric vehicles should not produce unexpected driving caused by their own electric drive system.
Simply put, the officially implemented "Technical Conditions for Motor Vehicle Operation Safety" stipulate that new energy vehicles should issue audible warnings when traveling at speeds below 20 kilometers per hour, and the low-speed warning sound system of Surabaya electric vehicles should alert everyone that the vehicle is in motion. Although the document does not explicitly state 'mandatory installation', domestic car companies attach great importance to it. In terms of passenger cars, this regulation has already been implemented first, and pure electric commercial vehicles are expected to follow closely behind.
