Abstract
The present application provides a charging control method and apparatus, a battery management system and a readable storage medium. The charging control method includes: 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; obtaining a preset waveform characteristic of a pulse charging waveform; where the waveform characteristic includes 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; and generating a charging request according to the pulse charging frequency and the waveform characteristic and transmitting the charging request to a charging device. The method is used for improving charging stability and safety of a battery.
