Charging control method and apparatus, battery management system and readable storage medium

A battery management system, comprising a processor;

• and a memory communicatively connected with the processor;
• wherein the memory stores an instruction executable by the processor, and the instruction is executed by the processor to cause the processor to perform a charging control method, and the charging control method comprises:
• 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.

A readable storage medium, wherein a computer program is stored on the readable storage medium, and when the computer program is operated by a computer, a charging control method is performed, and the charging control method comprises:

• 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.
