In the next few years, nearly 90% of the people in the world will have mobile phones. Nowadays, most people can't get used to not having mobile phones. Recent research shows that 70% of people use mobile phones while driving. In addition to making phone calls, people also use mobile phones to navigate, listen to music broadcasts, voice messages, video calls, and control the seats and air conditioning of the vehicle through mobile phones. Using mobile phones while driving has prompted many car manufacturers to provide WiFi in their cars.

Charging a smart phone in a car does cause safety risks - sometimes the connector is not suitable, the adapter may be lost, the charging cable may be tangled, it is very dangerous to connect the phone and the charging cable together when driving, and the power supply of the USB connector is also very low. Mobile devices can be quickly and effectively charged through the car wireless charging solution. As long as the mobile device is placed on the charging tray with the multi coil system, the device can be successfully charged.

As the screen size of the mobile phone increases, the use of the mobile phone increases, and the battery consumption increases accordingly. Ten years ago, a fully charged cell phone battery could last about a week. Today, the average battery life of smart phones is. Low battery power can cause people's anxiety. This makes automotive wireless charging solutions an important topic for automotive manufacturers.

Safe use of smart phones while driving has become an important part of measuring the driving experience. Although the mobile and automotive industries have successfully developed advanced automotive wireless charging solution technologies, the power consumption characteristics of these devices pose a new challenge: how to charge smart phones in cars without using cumbersome cables?

Induction charging is a mature technology. As early as 1891, Nikola Tesla demonstrated a technology: wireless "induction" energy transmission for incandescent lamps. It is also applied in daily life. For example, the wireless transmission of energy between the electric toothbrush and its charger - the wireless method converts the input voltage into a constant output voltage, and its effect is the same as that of the standard combination circuit. Applying this method to automotive wireless charging solutions can eliminate potential problems that may interfere with standard charging.
