Energy recovery system, referred to as: KERS system (Kinetic Energy Recovery System)
It will collect the heat energy generated by the car during braking to enhance overtaking. F1 cars usually brake to slow down, and the energy generated by the brakes is released in the form of heat. This is why we can always see red brake discs. For racing cars equipped with the KERS system, the gearbox will assist in taking on part of the braking task. The KERS system in the gearbox stores part of the energy generated during braking. When the car needs to accelerate, it is released as an auxiliary force to reuse energy. This is the working principle of the KERS system. This means that the fuel used when the car accelerates will be recovered when the car decelerates. It is expected that using the KERS system will allow the car to have 110% power nearly one-tenth of the time. As time goes by, the recovery and release capabilities of the KERS system have been further improved, and F1 racing cars will become less and less dependent on the engine and demand for fuel. However, unlike hybrid cars such as the Toyota Prius, F1 cars equipped with a KERS system must operate both the engine and the KERS system at the same time. The KERS system alone does not provide power to the car. The KERS system consists of three key parts, electronic motor, battery and energy control unit. The three parts belong to different technical categories, but they all need to be "tailor-made" for the F1 car.
