The invention discloses a charging control system and method, a storage medium and a vehicle comprising the same, and the method comprises the steps: collecting a voltage analog signal and a current analog signal based on a DSP processor; converting the voltage analog signal and the current analog signal, and respectively sending a voltage digital signal and a current digital signal; judging whether analog-to-digital conversion in a sampling period is finished or not, reading the voltage digital signal and the current digital signal according to a judgment result, and outputting a PWM signal corresponding to the sampling period; generating a switching value signal according to the PWM signal; and the output of the charging power is controlled through a switching value signal. According to the method, the number of instructions and the running time are shortened, the processing speed of digital signals is improved, the time of the processes of instruction fetching, decoding, operand fetching and the like is shortened, the processing capacity of the system is enhanced, and the charging efficiency is improved; and a plurality of modules are controlled at the same time, so that the complexity of programming is reduced, and the cost of the system is reduced.
