Battery charging apparatus and method

A battery charging method based on a battery charging system,

• wherein, the battery charging system comprises a power adapter and an electronic equipment, the power adapter comprises a communication interface and charges via the communication interface a battery of the electronic equipment;
• the electronic equipment comprises a communication interface, a charging control assembly and the battery;
• wherein both the charging control assembly and the battery are coupled with the communication interface of the power adapter via the communication interface such that the power adapter communicates with the charging control assembly and charges the battery, and the charging control assembly is also coupled with electrodes of the battery so as to detect a voltage of the battery;
• the battery charging method comprises:
• during charging a battery, first charging, by a power adapter, the battery in a regular charging mode;
• when an output current value of the power adapter is within a regular current range for a predefined time period, sending, by the power adapter, a quick charge inquiry communication with the charging control assembly;
• after receiving a quick charge command sent by the charging control assembly,
• adjusting, by the power adapter, an output voltage according to battery voltage information fed back by the charging control assembly;
• when the output voltage meets a quick charge voltage requirement predefined, adjusting, by the power adapter, an output current and the output voltage according to a quick charge mode so as to charge the battery;
• wherein, performing by the power adapter the quick chare inquiry communication with the charging control assembly comprises the following acts:
• sending, by the power adapter, a quick charge inquiry instruction to the charging control assembly, wherein the quick charge inquiry instruction is configured to instruct the electronic equipment to determine whether the voltage of the battery reaches a quick charge voltage value;
• judging, by the charging control assembly according to the quick charge inquiry instruction, whether the voltage of the battery reaches the quick charge voltage value;
• if yes, feeding back by the charging control assembly the quick charge command to the power adapter;
• and if not, feeding back by the charging control assembly a quick charge rejection command to the power adapter, wherein the quick charge command is configured to instruct the power adapter to enter into a quick charge mode.
