F1 kers how does it work

Ian Foley who inevented the system explains in this short video. A number of non electrical systems have also been developed for F1, most notably the Flybrid, designed by former Renault F1 engine boss Jon Hilton. The system is based on a flywheel and operates totally differently from the Electronic and Williams systems.

McLaren and Force India are both believed to have investigated similar systems. More F1 technical information can be found here: Racecar Engineering F1. Subscribe Newsletter. Your special offer X.

Illustration 1 KERS is based around the fact that energy cannot be created or destroyed, but it can be endlessly converted. When you drive down the road your car has kinetic energy, when you brake that kinetic energy is mostly converted into heat energy. With KERS, that wasted energy from the car's braking process is stored and then reused to temporarily boost engine power. Illustration 1 is a CAD image showing one type of recovery device installed on top of the gearbox at the rear end of the car.

However, the battery used to store the energy is very prone to battery fires and can cause electric shocks. The mechanical implementation, shown in Fig. To harvest the energy upon braking, the system uses the braking energy to turn a flywheel which acts as the reservoir of this energy. When needed, the redelivery of the energy is similar to that of the electric KERS implementation, the rotating flywheel is connected to the wheels of the car and when called upon provides a power boost.

The mechanical implementation of KERS is known to be more efficient than the electric equivalent due to the fewer conversions of the energy that are taking place. The implementations are similar to that what is used by hybrid passenger cars. The main difference is that in a hybrid car, the redelivered energy replaces the purpose of the engine and powers the car entirely. In Formula 1 this would be infeasible. Instead the energy is used in addition to the current engine.

The CVT subsequently handles the ratio of the torque provided by the motor connected to the engine and the torque from the flywheel. The obvious benefit of KERS is the boost provided. The KERS boost can provide drivers with an additional 80 bhp for up to 7 seconds a lap. This translates to more powerful acceleration which can make all the difference to a Formula 1 race. Drivers have been using it out of slow corners to help reach their top speed sooner as well as on straights to actually go past what would usually be their top speed.
