Wireless car charging solution: what is wireless car charging technology

 Providers of wireless charging solutions for automobiles have found that in recent years, the frequency of mobile phone use in people's daily life has gradually increased, and the power consumption of mobile phones has gradually accelerated, especially in daily life. The more we rely on our phone for its capabilities, the faster it drains its battery. Therefore, more and more people will not let go of every place where they can charge their mobile phones, and being able to charge mobile phones in the car is undoubtedly a very good choice. Automotive wireless charging solutions solve this problem.   The car wireless charging solution is that the traditional in-car charging method by using a car charger with a charging cable is not a very convenient and safe way. People need to unplug the cable when answering the phone. When driving, because the attention is occupied, if the cable is inserted into the charging hole, it is actually an operation with potential safety hazards, and the cumbersome and tangled charging also brings a very poor experience to the car owner. In addition, the instability of the cigarette lighter voltage will also cause certain damage to the mobile phone. In-vehicle wireless charging solves this problem.   The car wireless charging solution is the application of mobile phone wireless charging technology in the car. This technology provides a comfortable and convenient experience for charging mobile phones in the in-vehicle charging area. It also solves the problem of traditional charging methods. It is convenient, and there are many troubles such as forgetting to bring the charging cable.   If the car is equipped with a wireless charging launch board (or built in the center console), the user can put the mobile phone into the charging area to start charging, without further operations, just pick up the mobile phone and need to answer the call, and the charging process is interrupted. When you're done using your phone, put it back in the charging area to start the charging process all over again. The mobile phone battery is invisible and fully charged, which is safe and convenient. In addition to the in-vehicle wireless charging module of sensor technology, in addition to integrating sensor technology IPS technology, it can also integrate various modules to provide various in-vehicle intelligence and value-added services.

Wireless charging IC: principle of wireless charging

Wireless charging IC manufacturers recommend the principle of wireless charging : electromagnetic induction The alternating current of a certain frequency in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmitting end to the receiving end. At present, the more common charging solutions use electromagnetic induction. In fact, there is not much mystery in the technical realization of electromagnetic induction solutions. BYD applied for a patent for non-contact inductive chargers in December 2005 . Electromagnetic induction technology. Magnetic resonance It consists of an energy transmitting device and an energy receiving device. When the two devices are adjusted to the same frequency, or resonate at a specific frequency, they can exchange energy with each other. It is a technology currently being studied . radio wave This is a relatively mature technology, similar to the ore radio used in the early days. It is mainly composed of a microwave transmitting device and a microwave receiving device. It can capture the radio wave energy bounced off the wall and maintain a stable DC while adjusting with the load. Voltage. This method requires only a transmitter mounted on a wall plug and a " mosquito " receiver that can be mounted on any low voltage product. Wireless charging technology does sound futuristic, after all, everything is going wireless these days. Although wireless charging is in line with the current technology development trend, a major factor limiting its popularity in the market is the low charging efficiency.

Wireless charging single chip microcomputer scheme: wireless charging is the key link to help the intelligent era

The wireless charging microcontroller solution company analyzes that electric energy is an important basic energy source, which has brought great convenience to daily life and industrial production through continuous development. Today, in the 21st century, the production development of industrial society needs to rely more on electric energy. In the future, electric energy is bound to be one of the protagonists of green technology. Although the current power consumption problem can be solved by the traditional wired charging method, we still find that there are still a large number of disadvantages and charging problems of wired charging, whether in life or in industry. For example, when charging a mobile phone, in addition to the messy and lengthy power cords, it is necessary to find a suitable charging port and repeatedly plug and unplug it, which is really time-consuming and laborious, which makes the whole charging process very cumbersome; Electronic products such as computers, desk lamps, and stereos are undoubtedly the "hardest hit areas" for wired charging. In addition, as a new type of smart helmet, it needs to have multiple functions such as voice acquisition, video image acquisition, GPS positioning, storage, transmission, thermal imaging, night vision, 4G transmission, etc. The supply of electric energy is essential; because of its wide application For special application scenarios such as logistics, fire protection, electric power, coal mine, transportation, oil field, municipal construction, emergency command, etc., it is necessary to seal as much as possible to prevent water and dust. Therefore, how to make smart helmets more effective and safe charging is a major problem that needs to be solved urgently. At the same time, with the advent of the era of intelligence, automated and more convenient power supply methods are required. Traditional wired charging can no longer meet people's expectations for high-tech products, let alone meet the gradually upgraded electricity demand in industrial production. As a new high-tech technology, wireless charging, with its advantages of convenience, safety, durability and good user experience, allows users to completely get rid of the shackles of wires and build a more intelligent charging scene.
