What is the application of SMD power inductors in new energy vehicles
- 2020-07-02-

Everyone knows how SMD power inductors are used in new energy vehicles? Xiaoao will analyze this knowledge for everyone so that we can know how to choose when choosing a car;

SMD power inductorIt has a wide range of applications in the electronics industry, but chip inductors not only have a wide range of applications in the electronics industry, but also in the new energy automotive industry. With the rapid development of China's economy, automobiles have become an indispensable means of transportation. At the same time, the environmental problems caused by automobiles also bother us. For example, my country's first-tier cities have begun to implement a policy of restricting motor vehicle licenses. On the one hand, it is to solve the congestion problem, on the other hand, it is also to improve the air quality. At this time, new energy vehicles have entered our lives.

New energy vehicles are not only not affected by local purchase restrictions, but also receive strong support from China. Various subsidy policies have enabled the rapid development of new energy vehicles. At the same time, more and more people are choosing new energy vehicles as a means of transportation.

SMD power inductorIt is widely used in electronic circuits of new energy vehicles and is an important part of automotive electronic technology. According to the function, it can be divided into two categories: one is the vehicle electronic control system, such as sensors, DC/DC converters, etc.; the other is the vehicle electronic control system, such as vehicle CD/DVD audio system, GPS navigation system, etc., inductive solutions are positive Develop towards high efficiency, with small size and low noise, giving full play to the advantages of new energy vehicles.

At present, 70% of automotive innovation comes from automotive electronics. The average ASP of automotive electronics has increased from 4% in the 1970s to about 30% of the total vehicle cost. Among them, new energy vehicles and pure electric vehicles have a higher proportion. , Reaching more than 50%. The fundamental reason for the growth of automotive electronics ASP lies in the rapid increase in the number of electronic components for bicycles, and the ASP for optical magnetic devices can reach 4000-5000 yuan. There are four major directions in the development of automotive electronic information intelligence: 1) integrated safety system, 2) adaptive cruise system, 3) anti-collision and anti-collision alarm system, 4) communication system and electronic navigation. At present, autonomous driving with ADAS as the core technology is the main line that runs through it. How to improve the interaction between the driver and the car depends on the information exchange between the car and the external environment. The key is the car's radar, sound wave and other components.

First of all, the signal generator must have an adjustable frequency ultrasonic or other wave generated by the oscillator. The common domestic frequency is 40KHz or 58KHz. Changing the value of the inductance and capacitance can change the oscillation frequency. In short, inductance and other components It is standard. The second is the receiving end, where the filter can eliminate interference bands, such as after vibration. As a whole, the improvement of detection accuracy and distance places greater demands on the quality and quantity of electromagnetic devices. By 2019, most cars are expected to be equipped with automatic parking functions. By then, the number of bicycle detectors will be further increased, reaching 8-12, requiring a large number of transformers and inductive components.

From the above we can see thatSMD power inductorThere are also many uses in new energy vehicles. Many automotive electronic devices require the help of chip inductors to operate normally. In fact, it is not only the on-board electronic equipment of new energy vehicles, but also the charging piles of new energy vehicles. Maintain the normal operation of the equipment!
