Williams to supply battery system for Gen3 Formula E racecar

Williams Advanced Engineering (WAE) will supply the battery system for the next generation Formula E racecar, which will be used in the 2022-23 season and onwards.

The Gen3 racecar is expected to be more powerful than the Gen2 car (350 kW up from 250 kW) and will recoup more energy thanks to fast-charging rates that’ll enable up to 800kW of power to be utilised for pitstop recharging – a first for the all-electric motorsport.

WAE supplied the first-gen racecar with batteries but fell out of favour when McLaren Applied Technologies supplied a 56kWh battery for the second-generation Spark SRT05e vehicle. The Gen3 car spec is set to showcase a progression of the motorsport; namely when it comes to battery technologies, where improved energy density, lifecycle, durability, fast charging and power capabilities are expected to take centre stage.

“We’re 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,” said Craig Wilson, WAE Managing Director.

“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.”
