(1) The rise of high voltage and high current fast charging mode has achieved a breakthrough in high power
In recent years, fast charging technology has been rapidly popularized in the smart phone market. Mobile phone brand manufacturers and third-party charger manufacturers continue to invest in R & D and strive to promote faster charging products with higher power and safety through technological upgrading. After years of technological development, the continuous optimization of cell, data line and interface makes the whole charging link can withstand greater charging current and voltage; With the gradual improvement of charge pump technology, the voltage conversion efficiency of step-down circuit can be improved to nearly 99%, and the fast charging scheme with higher power can be realized with very low loss. On this basis, fast charging is no longer limited to the traditional high-voltage low current and low-voltage high current mode. Major mainstream mobile phone manufacturers continue to adopt high-voltage high current mode to break through the power limit of fast charging, from 20W, 30W, 65W to more than 100W. In July 2020, oppo released 125w flash charging technology, which can be charged in 20 minutes; In August 2020, Xiaomi released 120W wired second impulse technology to realize the commercial use of 120W power fast charging; It is expected that more manufacturers will break through the 100 watt bottleneck in the future. (2) Application of new materials to promote the upgrading of fast charging technology
As the third generation wide band gap semiconductor material, GaN has extremely strong stability. Compared with the traditional Si semiconductor material, GaN has the characteristics of large band gap, high thermal conductivity and high temperature resistance. The gallium nitride switching device made of Gan can greatly improve the switching frequency and reduce the loss, so that the charger can use smaller transformers and other inductive elements, so as to effectively reduce the volume, reduce heating and improve the efficiency, Gan charger effectively solves the contradiction between volume and power and improves the sense of user experience. Therefore, with the advantages of smaller volume, lighter weight and higher efficiency, Gan charger has become the mainstream development trend of the fast charging market. At the same time, with the rapid increase of fast charging power, higher requirements for the safety of the charging link are put forward. The new materials with outstanding thermal conductivity such as Shi Moxi and high conductivity heat dissipating gel are applied to the physical heat dissipation of the terminal battery. On the other hand, when introducing higher power fast charging, manufacturers provide a complete temperature control solution to improve the safety of fast charging applications in an all-round way.
