The invention discloses a quick charging simulation method. In the charging process of a mobile phone, a programmable power supply is electrically connected with a power connector in the mobile phone instead of a mobile phone battery, the whole charging process is simulated by regulating voltage values of the programmable power supply; in a charging simulation process, the voltage values and corresponding current values are displayed in real time by the programmable power supply. Detection on the whole charging process is completed through the charging simulation method disclosed by the invention, and moreover, the voltage and the corresponding charging current at all stages are monitored in real time; a charging curve is drawn; test time and research and development time are shortened, which is greatly helpful for research and development.
