"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 Porsche Board Member for Development Michael Steiner. "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 charging power of up to 11 kW, the sports car manufacturer has even reached the level of wired AC charging with its contactless charging system. The efficiency of energy transfer from the power grid to the battery is up to 90 percent.
An analysis showed that Porsche EV customers in the US charge approximately 83 percent of the time at home. Therefore, the potential for inductive charging is correspondingly great. The user-friendly Porsche Wireless Charging floor plate (length/width/height: 117/78/6 centimetres) can be installed in a garage, carport or open-air parking space and connected to the mains.
To inductively charge, hardware is also required on the car. The new Cayenne Electric will be the first model series to be ordered with optional Porsche Wireless Charging pre-installation and Porsche Wireless vehicle plate. Protected from stone chips and the effects of the weather, the receiver unit is located in the underbody of the vehicle between the front wheels. To initiate the charging process, the Cayenne simply 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 centimetres. To this end, the Cayenne lowers automatically. The base plate has a motion detector and foreign object detection. The charging process is automatically interrupted if a living creature gets between the vehicle and the floor plate or if a metallic object lies on the latter and heats up.
Porsche Wireless Charging is also integrated into the My Porsche app, so that charging processes can be tracked, and several vehicles can be authenticated. A special view in the 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 begins. Customers don't need to do anything else. Convenience functions familiar from AC charging, such as departure timer with cabin preconditioning, are also available for wireless charging.
The floor plate, which weighs 50 kilograms (110 pounds), is equipped with an LTE and WLAN module as standard, so that remote software updates and infrastructure support can also be provided in the future. Porsche Wireless Charging will initially launch in Europe in 2026. Other markets worldwide will follow.
How inductive charging works in detail
Inductive charging is known from smartphones and 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.
This innovative concept by Porsche 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 high-voltage battery in the Cayenne can store it.
Weatherproof, robust and extensively 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 plate 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.
A new dimension in fast charging
Those who want to travel as quickly as possible on long-haul journeys will be able to further rely on a very high charging capacity with the new Cayenne. Like the Macan and Taycan, which were previously leaders in their segments with 270 and 320 kW respectively, the Cayenne sets new standards, with the DC charging power up to 400 kW.
Conspicuously camouflaged prototype with fluorescent paint
At its first official appearances in the UK, the Cayenne grabbed the attention of many with an eye-catching wrap. The IAA MOBILITY in Munich is now equipped with a very similarly designed, innovative fluorescent paint. As soon as electricity flows, an exciting body image with brightly-coloured surfaces is created: Style Porsche designed the dynamic camouflage pattern. Individual paint sections are deliberately left out and remain dark. Five colour tones, from blue to violet, can be controlled in a targeted manner.
The innovative coating is made up of over 25 extremely thin layers. These include conductive primers, electrode and insulating layers as well as the actual electroluminescent material with colour pigments. Under alternating voltage, it emits light. In addition, there are more than 15 layers of clear coats. A total of 100 litres of clear varnish were applied. More than 30 sanding cycles and over 500 metres of cable are evidence of the effort behind this unique show car paintwork.
The innovative prototype will be on display for the first time at the IAA MOBILITY, which will take place from September 9 to 14, 2025 in Munich.
