Williams Advanced Engineering (WAE) has been awarded the exclusive contract to supply the Gen3 battery system of the ABB FIA Formula E World Championship.

The announcement revives a highly successful relationship that began when WAE was chosen as the first supplier of batteries to the electric racing series.

The company was instrumental in helping establish Formula E with a global audience, producing a bespoke battery system in just under a year — one that successfully launched and powered the entire grid over four seasons of racing.

The series has progressed year-on-year and there are now 24 cars competing at the highest level. The Gen3 spec will showcase advanced battery technology through improved energy density, lifecycle, durability, fast charging and power capability.

Craig Wilson, WAE’s managing director, said: “We are extremely proud to be appointed the Gen3 battery supplier for the ABB FIA Formula E World Championship, particularly as we have been an integral part of the series from the start.

“High performance batteries are one of WAE’s core competencies and I am confident we will add further value in the areas of energy density, thermal efficiency, overall performance and reliability.

“Racing in such a competitive environment is also a challenge for batteries, but one that we embrace. We look forward to supporting the series as it moves to its next exciting chapter.”
