How Porsche Inductive Charging Works

“Inductive charging is known from smartphones, but also from electric toothbrushes. The energy is transferred through the air via a magnetic field. For this purpose, a transmitter coil made of copper and ferrites is located in the base plate. Alternating current flows through this coil, which generates a magnetic field.

“Porsche’s innovative concept uses ultra-wideband technology to determine the vehicle’s relative position above the floor plate. When the optimal parking position is reached, the driver is informed. In the vehicle’s secondary coil, which acts as a receiver unit, the magnetic field then generates alternating current. A rectifier then converts this into direct current so that the Cayenne’s high-voltage battery can store it.

Weatherproof and Comprehensively Tested

“The Porsche Wireless Charging base plate is also suitable for outdoor use. All live components are protected from rain and snow. Even driving over the floor slab does not cause any significant damage. Electromagnetic radiation is limited to the underbody of the vehicle during charging. Extensive tests – including by TÜV Süd – have confirmed the robustness of the system. In addition, the floor plate is CE and UL certified, i.e., it meets EU and US-wide requirements for safety and environmental protection,” Porsche said.
