Abstract:
1. A system for enabling compatibility of wired charging with wireless charging, comprising: a wireless charging unit and a wired charging unit coupled to a power management unit by an interface circuit; the wired charging unit configured to charge the power management unit using a charging circuit in the power management unit; the wireless charging unit configured to charge the power management unit by using the charging circuit in the power management unit; the wireless charging unit further configured to autonomously turn off an output from the wireless charging unit in response to detection of an access signal of the wired charging unit from the interface circuit, where there are outputs from both the wireless charging unit and the wired charging unit; and the wired charging unit further configured to charge the power management unit via the interface circuit so as to cause a terminal in which the power management unit is located to enter a charging state normally and display the charging state on the terminal, after the wireless charging unit enters a no output state.
