In 2009 Formula One regulation changes allowed teams to store and reuse energy for the first time. Since then, Williams has developed world-leading expertise in both flywheel and battery Kinetic Energy Recovery Systems (KERS) for automotive, motorsport, public transport and energy applications.


Williams has developed high power density batteries and electric motors for a range of applications and market sectors where high performance, endurance and predictability are key customer requirements. We have expertise in the design and manufacture of the battery, motor generator unit, inverter and battery management system. But what really sets us apart is our ability to get these components to work together in unison.
