MUNICH: Porsche will soon be offering wireless charging technology for electric cars.
Porsche 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 maturity.
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, all-electric generation of the Cayenne will be the first Porsche model series that can be ordered with the vehicle-side equipment.
At the IAA Mobility in Munich (Sept 9 to 14), a Cayenne Electric prototype with fluorescent paint will demonstrate the innovative technology.
The world premiere of the new Cayenne Electric is 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," says 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.
The user-friendly Porsche Wireless Charging floor plate (length/width/height: 117/78/6 cm) can be installed in a garage, carport or open-air parking space and connected to the mains.
In order to be able to charge contactlessly, hardware is also required on the car.
The new Cayenne Electric (internal abbreviation: E4) 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.
For the charging process, the Cayenne then only 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 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 timer charging with preconditioning, are also available for wireless charging.
The floor plate, which weighs 50kg, is equipped with an LTE and WLAN module as standard, so that remote software updates and infrastructure support are also guaranteed in the future.
Porsche Wireless Charging will initially launch in Europe in 2026. Other markets worldwide will follow.
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.
