Porsche wireless charging breakthrough now makes home EV recharging as seamless as parking your smartphone on a pad. This revolutionary vehicle wireless charging technology was showcased by Porsche at the recent IAA Mobility show in Munich on its camouflaged electric Cayenne prototype model in bright fluorescent paintwork.
Wireless charging has already made a huge impact on mobile phones, making life much easier. Porsche could now be the first car manufacturer to offer the same user-friendly technology in its future electric cars.
“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.” Says the Deputy Chairman and Member of the Executive Board, Research and Development.
How does wireless charging work?
The basic principle involves the transfer of energy through the air via a magnetic field. To achieve this, copper coils are placed both in the base and receiving unit. When alternating current flows through this base coil, it creates a magnetic field.
This magnetic field then generates an alternating current in the receiving units’ coil. This alternating current is then converted to direct current via a rectifier, which can then be used to charge the batteries in the case of a vehicle.
The Porsche Wireless Charging System
The Porsche Wireless Charging unit consists of a floor plate (length x width x height: 1,170 x 780 x 60 mm) that can be installed in a closed or open-air parking space. It weighs around 50 kg and is connected to the mains. It is suitable for outdoor use and does not get damaged even when driven over.
According to Porsche, the 11 kW charging system has a 90% efficiency in transferring energy from the power grid to the battery, thereby reaching the speed levels of traditional home AC charging via cables.
Once the vehicle is parked over the floor plate and the parking brake is activated, the Cayenne automatically lowers its air suspension for optimal alignment and starts the charging process. The receiver unit is located between the front wheels, and for the energy to transfer, the distance between the floor plate and the receiver should be within a few cm.
The floor plate has a motion and foreign object detector. In case of a living creature or a metallic object getting in between the vehicle and the floor plate, the charging is automatically paused.
The Porsche wireless charging is also integrated into the My Porsche app so that the user can easily track the charging process from his mobile.
The Porsche Wireless Charging Review: In short
The electric Porsche Cayenne could well be the first model to come with an 11 kW wireless charging system. The new Cayenne is planned for a world premiere by the end of 2025, and the Porsche Wireless Charging will first be launched in Europe in 2026.
The Porsche wireless charging redefines convenience for EV owners and would certainly give Porsche models a unique competitive edge. As this inductive technology grows, competitors too will soon catch up.
Also, the wireless charging unit is being offered as vehicle-side equipment with an additional cost of around 8,000 USD. So, will consumers prefer the convenience over the extra cost? Only time will tell.
The electric era is just getting a whole lot more exciting.
