A method for controlling a Type C USB interface includes disconnecting a shielding housing of a Type C USB interface (J) from the ground of an electronic device, obtaining a level (V) of the shielding housing, determining, based on the obtained level (V), whether an external device is plugged into or unplugged from the Type C USB interface (J); outputting a signal to a CC pin of the Type C USB interface (J) when it is determined that the external device is plugged into the Type C USB interface (J) of the electronic device; and stopping outputting the signal to the CC pin of the Type C USB interface (J) when it is determined that the an external device is unplugged from the Type C USB interface (J) of the electronic device or that no the external device is connected to the Type C USB interface (J).

Electronic device having type C USB interface, method for controlling type C USB interface, and storage medium

A battery charging apparatus and method, a terminal, a power adapter, and a storage medium relate to the electronics field, where the method includes detecting temperature of a charging path in a battery charging apparatus, and when a power adapter supplying charging power for the battery charging apparatus works in a first working mode and a detected largest temperature value is greater than or equal to a preset threshold, instructing the power adapter to switch to a second working mode, decoupling a charging path corresponding to the first working mode, and coupling a charging path corresponding to the second working mode. This reduces impact of local heat accumulation on device performance during charging of a terminal battery, lengthens a device life span, and improves user experience.

Battery charging apparatus and method, terminal, power adapter, and storage medium

Some embodiments of the present invention provide a charger. According to the charger, a detection signal generation circuit actively sends a detection signal; a feedback circuit detects level signals on a sampling component, and generates a feedback signal according to the level signals; a switch component controls, according to the feedback signal, the charger to output a charging voltage; and when the level signals meet a preset condition (the preset condition is a preset condition that the level signals meet when an abnormal short circuit occurs on a charging interface), the switch component controls the charger to stop outputting the charging voltage.
