As shown in fig. 2, the charging unit 1 further includes a power supply processor 13, wherein:
the wireless charging emitter 11 and the wireless charging receiver 12 are arranged separately and are provided with matched electromagnetic coils or energy devices;
and the power supply processor 13 is respectively connected with the wireless charging receiver 12 and the battery unit 2, and is used for boosting the charging voltage and transmitting the boosted voltage to the battery unit 2.
In fig. 2, the wireless charging power supply module of this embodiment may be an electromagnetic induction type or a magnetic field resonance type in terms of a wireless charging manner. In the electromagnetic induction type, the wireless charging transmitter 11 of the charging unit 1 is set as a primary coil, the wireless charging receiver 12 is set as a secondary coil, and alternating current with a certain frequency in the primary coil can generate a certain current in the secondary coil through electromagnetic induction, so that energy is transferred from the primary coil to the secondary coil, that is, electric energy is transferred from the wireless charging transmitter 11 to the wireless charging receiver 12.
