The Working of Regenerative Brakes
A regenerative braking system is a form of supplementary and advanced system that is common in hybrid or electric cars. According to physics, the energy produced is never destroyed. It is hence evident that every time you step on your car`s braking pedal, the kinetic energy accumulated as it moves forward goes somewhere. In most occasions, the power is directly converted into heat and apparently lost to the surrounding.
However, as technology advances, automotive engineers are keeping up with the pace and have as a result found a solution of converting the energy using regenerative kind of brakes. Thanks to the modern braking system, the energy that was prone to be lost is converted to electricity and is used to recharge the batteries of the electric or hybrid vehicles.
But how does the regenerative braking systems work? The motor propelling the car has a dual function of driving and braking. On one direction it operates as a motor hence assisting in the conversion of electric energy into mechanical potential thus driving the car forward. On the other course, it is a braking system, running in an opposite direction and takes charge as a generator and as a result, slows the car down.
At that point, the kinetic energy from the wheels moves into the generator and as it rotates the energy is converted into electric power. The electrical energy accumulated is transferred to the batteries and as a result producing the charge. The regenerative brakes help save up to 70% of the energy that could have otherwise escaped. Complex circuits are brought on board to help determine whether the motor operates in a forward or backward direction. Capacitors are at most occasions used to store the electric energy for use at a later time. It is this saved energy that assists electric vehicles to get a more extensive driving range and help reduce emissions in hybrid motor cars.
