Review of Common Types Regenerative Braking System in Cars

Abstract:

The current developments in the automobile industry have prompted the creation of some systems in the car to reduce the losses resulting from it. One of these methods is the innovation of regenerative braking systems to recover the largest possible amount of energy wasted in the car’s traditional braking system. Several types of these systems have appeared since the last century, applying this concept of recovering the energy lost in the car’s brakes. They were systems that converted the lost kinetic energy into electrical energy stored in the car’s battery or mechanical or hydraulic. This research provides a review of the most prominent regenerative braking systems in cars since their appearance in the first half of the twentieth century, the importance of these methods, their features, and the types of cars that are suitable for each method in terms of the fact that they are cars with an internal combustion engine, electric and hybrid. Previous research shows that it is possible to recover 40 to 60% of the energy lost due to the traditional braking system, and accordingly, the energy efficiency of the car increases by an average of 25%, as well as reducing fuel consumption by 15%.
