  • Selecting charging parameter for component in charging system
    Patent number: 11489342
    Abstract: A charging method includes obtaining, by a charging device, a working status of a sensitive component in a terminal device, where the sensitive component interferes with a process in which the charging device charges the terminal device at a sensitive frequency, and the sensitive frequency is within a range of a charging frequency band of the charging device, determining, by the charging device, a safe charging parameter when the working status is an enabled state, where the safe charging parameter includes at least one of a safe charging frequency, a safe charging current, or a safe charging voltage, and charging, by the charging device, the terminal device using the safe charging parameter, where the sensitive component operates in a normal state when the wireless charging device charges the terminal device using the safe charging parameter.
