KERS - Kinetic energy recovery system
[attachment=28038]
What is kers?
The acronym KERS stands for Kinetic Energy Recovery System.
The device recovers the kinetic energy that is present in the waste heat created by the car’s braking process.
It stores that energy and converts it into power that can be called upon to boost acceleration
Operation
The system consists of a flywheel connected by a continuously variable transmission (CVT) to the drive-train.
Moving the CVT towards a gear ratio that would speed the flywheel up enables it to store energy, while moving towards a ratio that would slow it down allows it to release energy.
A hydraulic clutch separates the drive if the flywheel’s revs exceed the system’s limits
Parts of a KERS unit:
THE VARIOUS PARTS OF KERS ARE
Braking system: This is the part from where the energy to be stored is collected,
Storage System: This is used in the Electronic KERS where either the generator or motor will take over depending on whether the battery is being charged or discharged. Flywheel is used in Mechanical KERS. It is used to store and release mechanical energy.
KERS Control Unit: This unit is provided apart from the control unit provided by Microsoft. This unit controls the signals and the levels on how much energy should be transferred from one part of vehicle to another, meaning the storing of energy and releasing of energy. It also performs an array of other operations.
Advantages of kers in motor sports
Very high speeds can be achieved.
Very safe.
More efficient transmission of power is ensured by the use of the gearbox via several fixed ratios, a clutch and the CVT
60 kW power boost for 6.67 seconds
400 kJ of usable storage
A total system weight of 25 kg
A total packaging volume of 13 litres
