The original Flybrid Kinetic Energy Recovery System (KERS) was a small and light device designed to meet the FIA regulations for the 2009 Formula One season.
The key system features were:
- A flywheel made of steel and carbon fibre that rotated at over 60,000 RPM inside an evacuated chamber
- The flywheel casing featured containment to avoid the escape of any debris in the unlikely event of a flywheel failure
- The flywheel was connected to the transmission of the car on the output side of the gearbox via several fixed ratios, a clutch and a Continuously Variable Transmission
- 60 kW power transmission in either storage or recovery
- 400 kJ of usable storage (after accounting for internal losses)
- A total system weight of 25 kg
- A total packaging volume of 13 litres
The layout of the device was tailored exactly to meet the customer's requirement resulting in a truly bespoke solution that fitted within the tight packaging constraints of a F1 car.
