The charging solution of wireless charging coils

The sales volume of China's new energy vehicles reached 95,000 in 2015, and 67,800 in the first quarter of 2016. The rapid growth of China's new energy vehicle industry makes the market demand for charging piles increasingly large, and it is urgent to solve the charging problem Although there have been car companies and charging companies invested in the construction of charging piles, but the shopping mall is far from saturation and compared with charging piles, the construction cost of wireless charging is lower. It is understood that ZTE's construction of a set of wireless charging facilities costs about 20,000 yuan, and is not affected by site constraints and other factors That small make up today to explain this charge of wireless charging coil for us Wireless charging scheme of wireless charging coil coil can bring all kinds of wireless charger, filling rate can reach more than 85%, QI world wireless charging standard certification, low temperature, high safety Suitable for mobile phone bluetooth headset Electric cars, electric toothbrushes, electric toys Entrance card, etc., wireless charging skills From radio can transmit skills, can be divided into low power wireless charging and high power wireless charging two methods, the eagle electronic wireless charging coil products all choose soft magnetic composite material, disk casting CNC carving, common in the column and retaining wall design, can effectively reduce the signal interference, arrived in the transformation of energy efficiency more quickly Charging efficiency is higher For the feature of more integrated magnetic field, multi-stranded wire is used for all the deployment coils, which dissipates heat better and is not easy to burn. (1) Electromagnetic induction is often used for low-power wireless charging, such as Qi method for charging mobile phones, but induction (2) is used for wireless charging of electric vehicles. High-power wireless charging often uses resonant devices that transmit energy from power supply devices (chargers) to power consumption devices, which use the energy received to charge the battery and together for its own operation (3) Because of the magnetic field between the charger and electrical equipment to transmit energy, there is no need for wire connection between the two, so the charger and electrical equipment can do no conductive contact exposed。
