Charging control method and system, and terminal device, charger and storage medium

A system for charging control, comprising a memory, a processor and a computer program stored in the memory and executable by the processor which, when executed by the processor, causes the processor to carry out a method for charging control, applied to the system for charging control connected with a charger and a battery respectively, the method comprising:

• acquiring maximum charging power value of the charger;
• acquiring a first current value according to the maximum charging power value and a preset charging data table;
• wherein
• the preset charging data table comprises a first plurality of sample cutoff current values and a first plurality of sample cutoff voltage values corresponding to a target battery capacity value;
• and
• the first current value is a maximum value of current that the charger charged into the battery;
• determining a target cutoff current value from the first plurality of sample cutoff current values according to the first current value;
• wherein
• the target cutoff current value is less than the first current value;
• determining a target cutoff voltage value according to the target cutoff current value;
• wherein
• the target cutoff voltage value is one sample cutoff voltage value corresponding to the target cutoff current value, among the first plurality of sample cutoff voltage values;
• and
• charging the battery according to the target cutoff current value and the target cutoff voltage value.
