1. A charging control method, comprising:
obtaining a battery temperature and a battery state of charge;
determining a pulse charging frequency according to the battery temperature, the battery state of charge and a pre-calibrated corresponding relationship, wherein the pre-calibrated corresponding relationship is a corresponding relationship between a battery temperature, a battery state of charge, and a pulse charging frequency;
obtaining a preset waveform characteristic of a pulse charging waveform, wherein the waveform characteristic comprises a ratio range of an area of a positive pulse waveform to an area of a negative pulse waveform in each pulse cycle of the pulse charging waveform, an upper limit of the ratio range is 10 and a lower limit of the ratio range is 1;
generating a charging request according to the pulse charging frequency and the waveform characteristic; and
transmitting the charging request to a charging device.
