The company might have had trouble deciding on where to put the engine in the past (front? mid? roof? – no what about sticking it right out the back!) but when it comes to EV charging Porsche will soon be offering buried wireless inductive charging for electric cars.

The company will be the first car manufacturer to bring an 11kW charging system with a one-box base plate for battery-electric vehicles to market.

One-Box means that apart from the floor plate mounted at the parking lot, there is no longer any need to install a wallbox or control unit.

The new electric generation of the Cayenne will be the first Porsche model series that can be ordered with the equipment. Also in 2026, sales of the floor plate will start at Porsche Centres and online in the Porsche Shop.

With a charging power of up to 11kW, the charging is at the same level as wired AC charging with an efficiency of energy transfer from the power grid to the battery of up to 90 per cent.

The floor plate, which weighs a good 50kg, and works like the inductive charging for smartphones or 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.

Suitable for outdoor use, all the live components are protected from rain and snow. And electromagnetic radiation is limited to the underbody of the vehicle during charging.
