How to Turn Off an Electric Vehicle That Can Move Without Inserting a Key?

Electric vehicle remote controls have corresponding unlock and lock buttons. Pressing the lock button can secure the electric vehicle. Below is an introduction to the principles of electric vehicle remote controls: 1. Components: Electric vehicle remote controls are mainly divided into a transmitter part and a receiver part. The transmitter part is used to emit signals of a certain frequency, which control the electric vehicle; the receiver part is used to receive signals returned by the electric vehicle and decode them. 2. Working Principle: The principle of remote control for electric vehicles involves the transmitter encoding the control electrical signal first. It then uses infrared modulation or wireless frequency modulation (FM) or amplitude modulation (AM) to convert it into a wireless signal for transmission. The receiver picks up the radio waves carrying the information, amplifies and decodes them to retrieve the original control electrical signal. This signal is then power-amplified to drive relevant electrical components, achieving wireless remote control. 3. Range: For short-range, line-of-sight wireless remote controls, infrared remote control transmitters and receivers are generally used. The transmitting end encodes and transmits, while the receiving end receives and decodes. Examples include remote controls for TVs, air conditioners, etc. For long-distance wireless remote controls, frequency modulation or amplitude modulation transmission and reception technologies are typically employed, somewhat similar to the transmission and reception technologies of walkie-talkies or mobile phones, albeit operating at different frequencies.
