The wireless power receiving coil 101 may wirelessly charge the battery 10 based on a wireless charging method such as electromagnetic induction coupling or magnetic resonance coupling.

The electromagnetic induction coupling means that when the wireless charging coil 102 approaches the wireless power receiving coil 101, the energy signal emitted by the wireless charging coil 102 is coupled to the wireless power receiving coil 101 in an electromagnetic induction manner and is provided to the battery 10.

The magnetic resonance coupling means that a power transmission side resonance capacitor connected with the wireless charging coil 102 in series is arranged in the wireless charging coil 102, so that a power transmission side LC resonance circuit is formed; a power receiving side resonance capacitor connected in series with the wireless power receiving coil 101 is arranged in the wireless power receiving coil 101, so that a power receiving side LC resonance circuit is formed; and the power transmission-side LC resonance circuit and the power reception-side LC resonance circuit have the same resonance frequency. When the wireless charging coil 102 is powered on, the LC resonance circuit on the power transmission side can generate a high-frequency vibration magnetic field; the magnetic field and the electric field at any time at any position in the high-frequency vibration magnetic field are in an orthogonal relation, the phase difference is 1/2 pi, the magnetic field intensity is far higher than the electric field intensity, the space electromagnetic field can store energy, the power flow density of the combined electromagnetic wave is zero, and no energy is transmitted, namely the field cannot radiate outwards and cannot be lost inwards. When the wireless charging coil 102 approaches the wireless receiving coil 101, the wireless receiving coil 101 may fall into the range of the high-frequency vibration magnetic field, and since the receiving-side LC resonant circuit has the same resonant frequency as the transmitting-side LC resonant circuit, the receiving-side LC resonant circuit will generate resonance of the same frequency magnetic field, so that energy is coupled from the wireless charging coil 102 to the wireless receiving coil 101 in the form of magnetic resonance and provided to the battery 10.

In one embodiment, the batteries 10 are identical within each seat. In order to make the batteries 10 in the seats interchangeable, all the batteries 10 may be configured as the batteries 10 of the same specification and the same model, all the batteries 10 can be charged in the battery 10 charging device, and when the remaining capacity of the battery 10 in a certain seat is lower than the alarm value, the charged battery 10 may be directly replaced without checking the size and the model of the battery 10.
