Porsche introduces wireless charging solution
The device is compact, as Porsche writes that apart from the base plate mounted in the parking space, no wall box or control unit needs to be installed. The new, fully electric generation of the Cayenne will be the first Porsche model series to be available to order with the vehicle-side equipment. Sales of the base plate will also start in 2026.
Porsche also intends to present a prototype with luminous paint to demonstrate the technology at the IAA Mobility in Munich. The world premiere of the new Cayenne Electric is planned for the end of 2025.
With an 11 kW charge, Porsche has reached the level of AC charging wirelessly, which is an impressive feat. Furthermore, the German automotive manufacturer writes that energy transfer efficiency is up to 90 per cent.
In its press release, Porsche estimates that about 75 per cent of Porsche drivers’ charging sessions take place at home. The company sees a lot of potential for ease of use and convenience in this area, and the hardware installation is not obtrusive, as Porsche writes: “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.” The floor plate weighs about 50 kg, and is equipped with LTE and WLAN modules for software updates and infrastructure support. It is also protected from rain and snow, making it suitable for outdoor use, and it is CE and UL certified, so it meets EU and US-wide requirements for safety and environmental protection.
The process for using the charging technology is also simple: the plate uses wideband technology to determine the car’s position, after which it informs the driver when it is appropriately parked. “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.”
“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 Dr. 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.”
In 2018, Porsche also announced plans regarding its charging technology, stating that the company is pursuing three options. First: charging at home – possible via a charging station or inductively via a floor panel. Second: charging in cities, conceivable via the existing infrastructure.
