Williams Advanced Engineering has been given the contract to exclusively supply the battery system for the Gen3 Formula E car by the FIA World Motor Sport Council.
But the current Gen2 deal was awarded to McLaren Applied Technologies – supplier of the Gen1 motor and control unit – and its battery partner Atieva.
The Gen3 FE car will be boosted to 350kW – equivalent to 450bhp – from the current 250kW maximum and is set to be introduced for the 2022-23 season ahead of a minimum three-year cycle.
Craig Wilson, managing director of WAE, said: “We’re extremely proud to be appointed the Gen3 battery supplier, 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.”
