In the automotive industry, relays play an indispensable role.

First, in automotive electrical systems, relays are used to control lights. For example, headlights, fog lights, turn signals, etc., relays can accurately connect or disconnect the corresponding circuits according to the driver's operation to ensure the normal operation of the lights, while preventing the switch from being damaged by high current. In the starting system, the relay can deliver a large current to the starter at the moment of starting, ensuring the smooth start of the engine and protecting the ignition switch.

Secondly, automotive electronic equipment is also inseparable from relays. In the audio system, relays provide the required current for equipment such as power amplifiers, and can also automatically control the power on and off to save power. In the air-conditioning system, relays control the working status of equipment such as compressors and fans according to temperature parameters to improve efficiency and reliability. Safety systems such as airbags and anti-theft systems, relays quickly start the corresponding circuits in emergency situations or illegal intrusions.

In addition, in the field of new energy vehicles, relays control the on and off of charging circuits in electric vehicle charging systems to ensure safe and efficient charging. In hybrid vehicles, relays accurately control power switching, enable the engine and motor to work together, and improve fuel economy and power performance. In short, the application of relays provides a strong guarantee for the safe and reliable operation of automobiles.
