The powertrain and batteries are housed in the hull of the boat. With its powerful electric drive, the eFantom quietly reaches top speeds of around 85 kph (46 knots) and transports up to nine people across the water with minimal impact on the climate. It can then be quickly and conveniently charged at the marina with Ads-Tec Energy’s ChargePost.
The eFantom from Frauscher and Porsche was unveiled to the public in an exclusive presentation at Lake Garda, Italy. The first edition of 25 units of the eFantom will be available for delivery by Frauscher in 2024.
Ads-Tec Energy, a global leader in battery-buffered, ultra-fast charging technology, has provided significant support for the low-emission electric sports boat project. ChargePost, a compact, all-in-one ultra-fast charging system with integrated power electronics, battery storage and large monitors, charges the boat in less than 30 minutes. And the fact that it does not require costly grid expansion makes it the ideal solution for harbours. The battery storage can be supplied via a 22-kVA connection, which is available in any harbour, no matter how small. This enables fast, convenient charging of fully electric boats.
The system enables ultra-fast charging at up to 300 kW with one charging point or 150 kW with two charging points used simultaneously. No civil engineering work is required for the installation, meaning ChargePost can even be installed directly on the dock. Despite its minimal footprint of less than 2 m² (17 square feet), the system offers optimal speed and charging power.
The eFantom’s electric motor is based on technology used in the fully-electric Porsche Macan, with the power limited to a maximum of around 400 kW. All high-voltage components – in Porsche’s typical 800-V design – including the battery have also been adopted in the eFantom. According to Philip Ruckert, “eBoot” (electric boat) project manager at Porsche, “Ads-Tec Energy is known for innovative thinking and German craftsmanship. They were able to fully play to these strengths in the design of this project.”
The sports car manufacturer developed the eFantom in cooperation with Austria-based Frauscher Boats and sees it as having the potential to revolutionise an entire industry. Porsche also wants to be a pioneer for sustainable mobility beyond its range of racing and road vehicles. Measuring 2.5 metres (8.2 feet) wide and just over 8.5 metres (27.8 feet) long, the innovative electric boat is particularly stable in the water thanks to the location of the drive and batteries deep in the centre of the hull. It glides almost perfectly flat over the surface and is incredibly easy to manoeuvre. This means that, for the first time ever in an e-boat, it is also perfect for water skiing or wakeboarding.
This is not the first time that the two companies have worked together to open up innovative new fields in electromobility. For instance, Ads-Tec Energy was commissioned by Porsche to develop the ChargeBox fast-charging system which was unveiled at the launch of the Porsche Taycan in 2019. Over 1,000 ChargeBox charging points are now installed at Porsche dealerships around the world.
