With the widespread adoption of new energy vehicles and the continuous development of autonomous driving technology, traditional wired charging methods are increasingly exposed to problems such as low efficiency, frequent human intervention, and low automation levels. Wireless charging technology, with its convenience, efficiency, and intelligence, is becoming the key solution for the future energy supply of electric vehicles.
A wireless charging system consists primarily of a ground-based transmitter and an onboard receiver, using non-contact magnetic or electric field coupling principles to efficiently transfer energy. The process works as follows:
1. The ground transmitter converts AC power from the grid into high-frequency AC.
2. High-frequency current forms a magnetic field coupling between the ground transmitter coil and the onboard receiver coil.
3. The receiver converts the received energy into DC to charge the battery.
This process requires no plugging or unplugging of cables, and is fully automatic, making it both convenient and safe.
● Magnetic Field Coupling Wireless Charging (Mainstream Solution)
Currently the most widely used solution, this operates on a transformer-like principle with a transmission distance ranging from a few centimeters to several tens of centimeters, achieving an efficiency of up to 95%. Companies like Tesla have already integrated this technology into their future plans for autonomous electric vehicles.
● Electric Field Coupling Wireless Charging
This method transmits energy via capacitance between two plates. Although it offers high frequency, the transmission distance is limited, making it unsuitable for high-power vehicle charging.
● Long-distance Wireless Charging (Future Trend)
This technology uses microwaves, radio frequency, or lasers to transfer energy over distances of several meters, making it suitable for unmanned delivery vehicles or specific scenarios. However, it is not yet widely commercialized.
Goodbye to Plugging In: Especially suitable for shared vehicles, Robotaxis, and other autonomous vehicles.
Smart City Charging Infrastructure: No manual intervention required, supporting the development of L4/L5 autonomous driving.
Safer Charging: No exposed metal ports, reducing the risk of short circuits and electric shocks, and adaptable to all weather conditions.
High Compatibility: Can be embedded in the ground, parking spaces, or garage floors, without taking up extra space.
Tesla has already been planning wireless charging systems, particularly for its Robotaxi autonomous vehicles.
In the future, vehicles will automatically dock in the wireless charging zone after returning to the charging station, quickly replenishing energy. This method is not only efficient but fully automated, paving the way for a charging network that requires zero human intervention.
Advanced market solutions, such as magnetic resonance-based wireless charging technology, have already achieved efficiencies of up to 95%, which is comparable to wired charging.
