As a kind of preferred implementation, in order to guarantee the reliability of opposite end charging/discharging apparatus, can before determining the current mode of operation of wireless charge/discharge unit, judge the identity legitimacy of the transmit leg of wireless signal; Perhaps, whether the transmit leg of judging wireless signal is in the effective range.For example, can judge whether transmit leg is legal by the content of the identification code of in wireless signal, carrying.In this way, reduced the possibility that abnormal conditions take place terminal in charge and discharge process, for example, can avoid terminal when power supply, limited electric weight to be sent to the situation appearance of incorrect opposite end equipment to be charged, thereby save resource.
Wherein, the identification code among the step S104 can be that the user sets in advance, also can arrange by other means, and in the specific implementation, can be to discharge and recharge a end in the two ends identification code is carried to send to opposite equip. in the wireless signal.For example, can be that a side's to be charged equipment sends to opposite equip. with identification code, also can be power supply one side's equipment sends.As a kind of preferred implementation, can also be that charging or the equipment of initiatively initiating a side of powering send above-mentioned identification code, and terminal can judge that the transmit leg of wireless signal is equipment to be charged or wireless charging device according to this identification code after receiving identification code; Transmit leg at wireless signal is under the situation of equipment to be charged, can determine that the current mode of operation of wireless charge/discharge unit is emission mode; Transmit leg at wireless signal is under the situation of wireless charging device, can determine that the current mode of operation of wireless charge/discharge unit is receiving mode.In this way, terminal can be adjusted self working mode according to the needs that discharge and recharge opposite equip. easily, has improved the use flexibility of this terminal.
In the specific implementation, can only arrange one in the terminal and discharge and recharge coil, be that the control of receiving element or transmitting element realizes the switching of wireless charge/discharge unit mode of operation between emission mode and receiving mode by the other end that this coil is linked to each other.For example, link to each other (namely with receiving element discharging and recharging coil, the mode of operation of charge/discharge unit is receiving mode) situation under, can will be converted into direct current signal from the AC signal that discharges and recharges coil by receiving element, and by the wireless charging interface be the battery charge of self; And link to each other with transmitter unit (namely discharging and recharging coil, the mode of operation of charge/discharge unit is emission mode) situation under, can will be converted into AC signal from the direct current signal of external power source by transmitter unit, and send to equipment to be charged by the coil that discharges and recharges that links to each other with transmitter unit.
Wherein, there are two aspects in the AC signal source that discharges and recharges coil:
