Application of Electro-Mechanical Kinetic Energy Regenerative System and E-Lock Differential for an Electric Vehicle: A Review

In this study, research work on electro-mechanical kinetic energy generating systems and e-lock differential is highlighted. Kinetic energy recovery systems (KERSs) only store and restore energy while braking. During braking, kinetic energy is primarily converted to heat and squandered. Vehicles with KERS may utilize part of this kinetic energy to help brake. KERS cars still lose heat while braking, but less because some energy is retained. At the stroke of a button, the stored energy is turned into kinetic energy, providing the vehicle a power boost. KERS needs two things: a mechanism to store and return energy to the powertrain and a location to store this energy. KERS systems are electrical, electro-mechanical, or mechanical. The distinction is in how they convert and store energy. The electronic locking differential is a device housed in the rear axle that allows both rear wheels to turn at the same speed. The electronic locking differential provides additional traction should your vehicle become stuck. We can activate the differential electronically and shift it on the fly within the operating speed range. The electronic differential disengages when the vehicle speed exceeds a set value and it re-engages when the vehicle speed goes below a set value. The electronic locking differential (ELD) is for off-road use only and is not for use on dry pavement. Using the electronic locking differential on dry pavement can result in increased tire wear, noise, and vibration.
