In the lead-up to the IAA Mobility 2025 event in Munich next week, Porsche announced that it will soon be offering more user-friendly inductive vehicle charging. The company says it will be the first car manufacturer to bring an 11-kW 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 all-electric Cayenne will be the first Porsche model that can be ordered with the vehicle-side equipment. In 2026, sales of the floor plate will start at Porsche centers and online. At the IAA, a Cayenne Electric prototype with fluorescent paint will demonstrate the technology, but the world will have to wait for the production vehicle’s unveiling planned for the end of 2025.

“Ease of use, suitability for everyday use, and charging infrastructure are still the decisive factors when it comes to the acceptance of electric mobility,” said Dr. Michael Steiner, Deputy Chairman and Member of the Executive Board, Research and Development, at Porsche. “We are proud that inductive charging will soon be available in series production at Porsche. Charging an electric car at home has never been so easy and convenient.”

With a maximum 11-kW charging power, the company has reached wired AC charging levels with its contactless charging system. The efficiency of energy transfer from the power grid to the battery is up to 90%.

With around 75% of all charging processes in an all-electric Porsche taking place at home, Porsche sees great potential for inductive charging. The Porsche Wireless Charging floor plate can be installed not only in garages or carports but also in open-air parking spaces and connected to electrical mains. When ordered, a Porsche Installation Service electrician will install the inductive floor plate and put it into operation.

While the supplier for the system has not been publicly disclosed, Porsche does partner with other companies for different aspects of its charging ecosystem such as ChargePoint for public charging access and Qmerit for installation services for wired charging hardware.

To charge contactlessly, car hardware is required. The Cayenne Electric will be the first production model that can be ordered with optional wireless charging pre-installation and a wireless vehicle plate. The underbody receiver unit between the front wheels is protected from stone chips and the effects of the weather.

For charging, the Cayenne has to be parked above the floor plate. The contactless transfer of energy between the two charging units takes place over a distance of a few centimeters, so the Cayenne lowers automatically to enable the process.

A special surround view parking function makes it easier to steer the Cayenne to the optimal charging position. As soon as the parking position above the floor plate is reached and the parking brake is activated, the charging process can begin. Convenience functions familiar from AC charging, such as timer charging with preconditioning, are also available for wireless charging.

The base plate has motion and foreign object detectors. The charging process is automatically interrupted if a living creature or metallic object gets between the vehicle and the floor plate. The wireless charging control and tracking will be integrated into the My Porsche app, and several vehicles can be authenticated.

At 117 cm (460.71 in) long, 78 cm (31 in) wide, and 6 cm (2.4 in) tall, the 50-kg (110-lb) floor plate is equipped with an LTE and WLAN module as standard for remote software updates and infrastructure support.

For inductive charging, popularized by smartphones and electric toothbrushes, energy is transferred through the air via a magnetic field. Alternating current flows through a transmitter coil made of copper and ferrites located in the base plate, generating a magnetic field.

In the vehicle’s secondary coil, which acts as a receiver unit, the magnetic field then generates alternating current. A rectifier converts this into direct current so that the Cayenne’s high-voltage battery can store it.

Extensive testing, including by TÜV Süd, has confirmed the robustness of the system. The floor plate is CE- and UL-certified, so it meets EU and U.S.-wide requirements for safety and environmental protection.

The base plate is suitable for outdoor use thanks to all live components being protected from rain and snow. Even driving over the floor plate does not cause any significant damage. Electromagnetic radiation is limited to the underbody of the vehicle during charging.

For the new Cayenne, Porsche promises electric traveling as quickly as possible on long-haul journeys enabled by high charging capacities. Like the electric Macan and Taycan, with 270 and 320 kW, respectively, it says that the electric Cayenne will set new standards, with DC charging power up to 400 kW and Porsche Charging Lounges for optimal recharging.

The IAA Mobility show Cayenne prototype is equipped to catch the eye of attendees with an innovative fluorescent wrap in a pattern designed by Style Porsche. When electricity flows, parts of the body glow brightly in five colors from blue to violet. Individual sections are deliberately left out for contrast.

The coating is composed of over 25 thin layers that include conductive primers, electrodes, and insulating layers, as well as the actual electroluminescent material with the color pigments that emit light. The finish features more than 15 layers of clear coats, a total of 100 L (26.4 gal) of clear varnish, more than 30 sanding cycles, and over 500 m (1640 ft) of cable.

Porsche Wireless Charging will initially launch in Europe in 2026, with other markets worldwide to follow.
