摘要： The present disclosure relates to a method for checking a charging parameter. The method includes: after a communication channel between a terminal and a charger is successfully established, reading, by the terminal, charging capability information of the charger in a preset manner; comparing a maximum capability value of the charger for each preset charging parameter with a target value that is corresponding to a corresponding preset charging parameter and that is stored in the terminal, and determining a minimum value as a first configuration value for the corresponding preset charging parameter; writing, into the charger, the first configuration value that is obtained by means of comparison and that is for each preset charging parameter; reading a second configuration value of the charger for each preset charging parameter; and sending, by the terminal, a charging acknowledgment instruction to the charger after determining that all preset charging parameters are successfully configured.

摘要： A power adapter, a cable, and a charger, where the power adapter includes an output port, a comparator circuit, and a voltage control and shaping circuit. The output port includes a voltage output terminal, a signal feedback terminal, a first ground terminal, and a second ground terminal. The comparator circuit is electrically connected to the signal feedback terminal, and is configured to compare a reference voltage with a charging input voltage of a to-be-charged device that is fed back by the signal feedback terminal to obtain a comparison voltage and output the comparison voltage to the voltage control and shaping circuit.

摘要： This application provides a power supply system for a terminal device, and a chip, and relates to the charging field. The power supply system includes a battery pack, a bypass circuit, a voltage step-down circuit, and a controller. The battery pack includes at least two batteries. The controller is configured to: when the batteries in the battery pack need to be switched to a series mode, control the voltage step-down circuit to work and control the bypass circuit to stop working, and is further configured to: when the batteries in the battery pack need to be switched to a parallel mode, control the bypass circuit to work and control the voltage step-down circuit to stop working. In the system, switching between the series mode and the parallel mode can be automatically implemented based on an actual situation, so that endurance and stability of the terminal device are improved.

摘要： A motor vibration control method and an electronic device can implement vibration of a motor when a loading capability of a battery is low. A battery status is obtained when a first motor vibration waveform vibration request is received. The battery status includes a battery temperature, a battery temperature and a battery level, or a battery power supply capability. A motor vibration parameter is switched if the battery status meets a preset condition, where the preset condition is that the battery power supply capability is lower than a first threshold, the battery temperature is lower than a second threshold, or the battery temperature and the battery level are lower than a third threshold array. The motor vibration parameter includes a motor vibration waveform or a motor vibration input voltage. The motor is driven to vibrate based on a switched motor vibration parameter.
