Regenerative Brakes Use Sophisticated Technology To Recharge Batteries And Extend The Range Of Electric Cars.

Depending on the power of the car and its electric motors, this auxiliary braking force is so powerful that manufacturers program an electronic module to avoid accidents and ensure better running.

Although regenerative brakes work to give electric cars greater autonomy, it is important to understand how everything actually works to maintain the safety of both the vehicle and the driver.

Regenerative brakes also reduce speed and stop the vehicle, as well as recovering the charge from electric and hybrid car batteries.  Even in more modern car models, this technology has a very simple concept.

Understand how regenerative brakes work

The electric motor, responsible for towing the vehicle, acts as a kind of power generator to power the batteries directly as a way of increasing the autonomy of the vehicle.

In this way, the electric motor begins to power the batteries each time the driver applies the brakes or decelerates.  During braking, the sensor sends signals to an electronic module that converts the thruster into a generator, taking advantage of all the motion of the car’s wheels, called kinetic energy, which generates energy, which is then sent to batteries.

Depending on the electric car and its power, the regenerative braking capability is strong enough to stop the vehicle from applying conventional wheel brakes.

The importance of regenerative breaking

In a brief example, when the driver has to get down, the power regeneration system serves as a very effective “engine brake”, helping to recharge the batteries, generating power and reducing the speed of the car.  .

Another example of the importance and efficiency of regenerative brakes is the sports model Porsche Tacon, where conventional brakes are actually enabled to assist electric motors in moments of strong braking.

According to Porsche data, the power regeneration system accounts for about 90% of the car’s braking performance and has the potential to add another 4 km to the autonomy of the battery, at 200 km / h until braking.  Total of the car.  Regenerative brakes contribute to preserving wheel brakes and increasing the life span of friction components such as discs, pads, drums and lining.

Essential care

If the car is fully charged, 100% charged, regenerative brakes may not work as power generators, but this is more common in hybrid models because the combustion engine acts as a generator.

This is because the battery is not capable of collecting power beyond its limits as a fuel tank.  Therefore, it is important to warn that any attempt to recharge under such conditions may overheat the engine, putting the energy accumulator at risk of exploding.  This limitation is linked to the fact that fast recharges in electrosposts do not exceed 80% efficiency for safety reasons.

FAQ

How does the regenerative brake work?

Regenerative braking recovers some kinetic energy, which otherwise turns into heat, and converts it into electricity instead.

What is regenerative braking in an electric vehicle?

In a battery powered electric vehicle, regenerative braking (also called regeneration) converts the kinetic energy of the vehicle into chemical energy stored in the battery, where it can then be used to drive the vehicle.

How much coverage does regenerative braking add?

Generally regenerative braking adds 10-15% more range with urban driving and a negligible amount with highway driving.

What type of braking is regenerative braking?

Regenerative braking systems (RBSs) are a type of kinetic energy recovery system that transmits the kinetic energy of a moving object into a potential or stored energy to slow down the vehicle and, consequently, increase fuel efficiency.  These systems are also called kinetic energy recovery systems.

What are the benefits of regenerative braking?

Advantages of electric vehicle with regenerative braking system

About 30% savings on energy use.

Increased battery autonomy.

Ideal for activities with frequent stops and goings on.

Use is zero, even if the vehicle is turned on or off.

Maximum efficiency since the electric motor has maximum torque at zero rpm.
