Williams Advanced Engineering (WAE) is working with fellow UK firm, OXIS Energy Ltd, on the production of a world-first battery system, designed for an all-new 40ft electric luxury boat. The craft will be the world’s first ever luxury boat to be powered by Lithium Sulfur (Li-S) cell and battery systems technology.

WAE will be responsible for the state-of-the-art 400 kWh battery system, which comprises ultra-light, high-power/high energy density Li-S cells – provided by OXIS Energy Ltd – and the battery management system (BMS). The design and manufacture of the cell modules, the BMS and its installation will be carried out by WAE at its dedicated UK battery facility.

The luxury boat, from Yachts de Luxe (YdL) of Singapore, has been designed by the renowned boat designer, Jean Jacques Coste.

Craig Wilson, Managing Director, WAE, says: “We’re extremely proud to be involved in this exciting initiative which we believe showcases the way in which the UK is positioning itself to be at the forefront of this emerging market. In addition, the application has relevance for a number of additional sectors including aerospace, aviation, urban air mobility, transportation and defence.”

Huw Hampson-Jones, CEO, OXIS Energy, adds: “Williams has a significant level of battery technology expertise and skills across the range of vehicle applications. This expertise, combined with OXIS’s world leading Centre of Expertise in Lithium Sulfur, gives vehicle manufacturers, on land, sea and in the air the confidence to engage with our next generation of rechargeable battery technology, with the necessary assurance to achieve their desired mission profile, at a high level of performance and safety – far in excess than what current technology offers.”

WAE was the original supplier of batteries to the entire grid of FIA Formula E World Championship cars in 2014, a relationship that has been revived for 2022-23 season with WAE being awarded the exclusive contract to supply the Gen3 battery system. WAE also supplies battery systems to ETCR and Extreme-E.
