1, fast charging is a charging method that can make the battery reach or close to the fully charged state within 1~5h. Commonly used in traction batteries need to restore the full state of charge in a relatively short period of time when charging. Normal charging of the battery takes about 10 ~ 20h, how to quickly charge without harming the performance and life of the battery, is a popular research topic of concern.
2, cell phone fast charging principle is to improve the charging voltage or current input value. However, to truly realize the fast charging of cell phones, supporting circuits and hardware are also needed. The current fast-charging technology mainly includes Qualcomm's Quick Charge and MediaTek's Pump Express.
3. Fast charging will reduce battery life to a certain extent, and long-term fast charging may lead to electrolyte decomposition, resulting in deposits on the electrodes. At the same time, the high temperatures generated by fast charging may damage the battery cells. Even ordinary charging reduces battery life, and the damage to the battery from fast charging is usually acceptable compared to the speed of cell phone replacement.
