The breakthrough of wireless transmission technology is to find a way to \"catch\" electromagnetic waves, that is, to use the \"resonance\" principle of physics - two objects with the same vibration frequency can efficiently transmit energy.

The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car. Usually when charging, the main coil with a flat iron core, the coupler, is manually inserted into a gap in the secondary core, so that energy can be transferred from the main circuit located at the bottom to the battery. Nissan Rubik's Cube electric vehicle: Uses electromagnetic induction to provide power between the supply coil and the receiving coil. A receiving coil device is installed on the chassis of the car, and another power supply coil device is installed on the ground. When the electric vehicle drives to the power supply coil device, the receiving coil can receive the current of the power supply coil, so as to charge the battery. Japanese wireless charging hybrid bus: electromagnetic induction, the power supply coil is buried in the concrete of the charging station. After the car is on the charging platform, when the car coil is aligned with the power supply coil (coincidence), there is an indicator on the dashboard of the car will light up, and the driver will press the charging button to start charging.
2: Concise answer provides key information Magton wireless charging principle is a wireless charging technology using the principle of electromagnetic induction.
By establishing an electromagnetic induction field between the charger and the charging device, the electromagnetic wave emitted by the charger is received by the charging device and converted into electrical energy, thus realizing the charging of the device.
