When a vehicle is parked over the charging pad, the transmitter coil inside the pad generates an alternating electromagnetic field. This magnetic field penetrates the chassis gap, inducing current in the onboard receiving coil, with the entire process requiring no physical contact. Modern systems can achieve an effective charging distance of 10-20cm, with some laboratory prototypes even achieving a breakthrough of 30cm.
It is noteworthy that the The BMW i8 prototype has achieved 30kW wireless fast charging, with efficiency comparable to traditional DC charging piles. The recently announced road-embedded system by Volvo further makes dynamic charging possible.
Shenzhen's public transportation system has deployed over 300 wireless charging stations, with operational data showing a 40% reduction in maintenance costs. The autonomous shuttle project at London Heathrow Airport achieves uninterrupted 24-hour operation through embedded charging devices.
In the private sector, Tesla's newly applied snake-shaped coil patent, through adaptive alignment technology, increases the position tolerance rate to ±15cm, significantly reducing parking precision requirements.
Measured data shows that vehicles equipped with wireless charging save an average of 23 minutes of operational time per week. The safety of charging in rainy weather has increased by 87%, completely eliminating the risk of electric leakage. Satisfaction among elderly car owners reaches 94%, significantly higher than traditional charging methods.
The pilot project in the Suzhou Industrial Park embeds the charging module into the lamp post base, allowing charging as soon as you park. The BYD Yunba system enhances vehicle range by 300 kilometers per day through platform charging design.
Wireless charging is not a substitute, but a new paradigm that redefines the charging scenario. — Marc Landy, Director of Technology at the International Energy Agency
Full life cycle assessment shows that wireless systems reduce copper consumption by 23%. Used in conjunction with photovoltaic carports, carbon footprints decrease by 61% compared to traditional charging. Research from the University of Chicago predicts that comprehensive popularization could reduce urban grid load by 18%.
Currently, the efficiency of commercial systems is generally in the range of 88-91%, which still lags 5-7% behind top DC piles. Electromagnetic compatibility issues require installations to meet a 1.2-meter spacing requirement, limiting space utilization.
