Battery Charging Apparatus and Method, Terminal, Power Adapter, and Storage Medium

A power adapter, electrically coupled to a battery charging apparatus, the power adapter supporting at least two working modes, and the power adapter comprising:

• a communications interface;
• a communications device coupled to the communications interface and configured to communicate with the battery charging apparatus using the interface to receive instruction information from the battery charging apparatus, the instruction information indicating a working mode of the power adapter;
• a power device coupled to the communications interface and configured to supply charging power for the battery charging apparatus using the communications interface;
• and
• a switching switch coupled to the power device and configured to control a working mode of the power device and
• the communications device being further configured to switch among working states of the switching switch according to the instruction information from the battery charging apparatus, to control to control the working mode of the power device.

A terminal, comprising:

• a battery;
• and
• a battery charging apparatus coupled to the battery, the battery charging apparatus comprising:
• a temperature collector configured to:
• detect temperature of a charging path in a charging device;
• and
• transfer the detected temperature to a charging control device;
• the charging device comprising at least two charging paths, the at least two charging paths being coupled in parallel, and the charging device being configured to couple, according to an instruction of the charging control device, a charging path corresponding to a working mode of a power adapter;
• and
• the charging control device being electrically coupled to the temperature collector, the charging device, and the power adapter and configured to:
• indicate a working state of the charging device and a working state of the power adapter according to the temperature from the temperature collector;
• and
• instruct the power adapter to switch to a second working mode and the charging device to decouple a charging path corresponding to a first working mode and couple a charging path corresponding to the second working mode when the power adapter works in the first working mode and a largest temperature value from the temperature collector is greater than or equal to a preset threshold.
