Kinetic Energy Recovery System
The technology’s outlook across the automotive market
Over the past two decades, the automotive industry has focussed on minimizing powertrain energy losses with advancements in combustion process, transmission design and lightweight material usage. Kinetic Energy Recovery System (KERS) is one of the innovations among energy harvesting and regeneration technologies which has achieved acceptance in mainstream automotive powertrain design. The technology offers a higher cost benefit for pure IC engine vehicles over hybrid-electric vehicles (both mild and full) and is popular across European, Chinese and South-Asian markets. The basic working principle of KERS involves storage of kinetic energy extracted during deceleration of the vehicle, and release the same back into the powertrain on demand. The harnessed energy gives an option of additional boost, which otherwise would have been dissipated into the environment as heat or sound energy.
