in this embodiment, whether the charging condition is satisfied may be determined by the pulse signal, and specifically, the pulse signal with a preset length sent by the wireless charger is received, where the preset length may be set by factory default. For example, the predetermined length may be 8 bits, 10 bits, 16 bits, etc., without limitation. For example, the wireless charger sends a pulse signal with a preset length of 8 bits, for example, the pulse signal with 8 bits is 10111001 (the pulse signal is 100ms as one bit and divided into high and low levels), the first two bits are fixed pulses, the first bit (1) is high, the second bit (0) is low, and the terminal recognizes that the first bit is high, and the second bit is low, so that the wireless charger can be considered to send an authentication sequence.

and step S54, when the target number sequence is consistent with the preset number sequence, determining that the adaptation between the wireless charger and the terminal meets the charging condition.

Further, referring to fig. 8, the step S50 further includes:
step S55, obtaining the matching authentication information of the terminal and the wireless charger;
step S56, in the case that the authentication information is successfully matched, determining that the adaptation between the wireless charger and the terminal satisfies a charging condition.

The user may set the authentication information on the terminal or the trusted third party terminal (e.g. server, etc.) when the terminal or the wireless charger is used for the first time, then send the authentication information to the wireless charger through the terminal or the trusted third party terminal to save as authentication information, and when the wireless charging is needed next time, the user inputs the authentication information in the terminal and sends the authentication information to the wireless charger, so that the wireless charger compares whether the saved authentication information matches with the received authentication information.
Alternatively, the authentication information may be authentication information with a terminal randomly generated number as an intermediary. Specifically, the terminal generates a random number and sends the random number to the wireless charger, the wireless charger carries out digital reply aiming at the random number and returns the digital reply to the terminal, wherein the digital reply comprises one or more kinds of information such as a wireless charger model, a charging voltage range, a charging current range, a chargeable terminal model and the like, the terminal verifies whether the one or more kinds of information are consistent with the information of the wireless charger which is stored in the terminal and can be selected, if so, the wireless charger is successfully matched with the terminal, namely, the adaptation between the wireless charger and the terminal meets the charging condition; if the wireless charger is inconsistent, the wireless charger and the terminal fail to be matched.
