Charging circuit, electronic device, charging method and charging device

A charging method applied to a charging circuit, wherein the charging circuit comprises a plurality of batteries connected in series, the charging method comprising:

• acquiring an asynchronous charging instruction;
• and
• controlling, according to the asynchronous charging instruction, at least one battery of the plurality of batteries and one or more other batteries of the plurality of batteries to perform asynchronous charging, so that the at least one battery and the one or more other batteries are not in a maximum charging power stage at a same time,
• wherein the controlling the at least one battery and the one or more other batteries to perform asynchronous charging comprises:
• pre-charging the at least one battery;
• judging whether the at least one battery is in a constant current charging stage;
• in response to the at least one battery being in the constant current charging stage, controlling, according to a preset asynchronous charging strategy, the one or more other batteries to perform asynchronous charging;
• judging whether the at least one battery is in a constant voltage charging stage;
• and
• in response to the at least one battery being in the constant voltage charging stage, controlling, according to the preset asynchronous charging strategy, the one or more other batteries to enter a constant current charging stage.

An electronic device, comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor,
• wherein the processor is configured to:
• acquire an asynchronous charging instruction;
• and
• control, according to the asynchronous charging instruction, at least one battery of a plurality of batteries and one or more other batteries of the plurality of batteries to perform asynchronous charging, so that the at least one battery and the one or more other batteries are not in a maximum charging power stage at a same time, wherein the plurality of batteries are connected in series,
• wherein in controlling the at least one battery and the one or more other batteries to perform asynchronous charging, the processor is further configured to:
• pre-charge the at least one battery;
• judge whether the at least one battery is in a constant current charging stage;
• in response to the at least one battery being in the constant current charging stage, control, according to a preset asynchronous charging strategy, the one or more other batteries to perform asynchronous charging;
• judge whether the at least one battery is in a constant voltage charging stage;
• and
• in response to the at least one battery being in the constant voltage charging stage, control, according to the preset asynchronous charging strategy, the one or more other batteries to enter a constant current charging stage.
