How Does Regenerative Braking Work?

Can Someone Explain Regenerative Braking? — Jeff’s Auto Repair

Most Lynnwood, Washington, residents appreciate how our local preservationists have saved many historic structures. Keeler’s Corner, for example, is the beloved service station now listed on the National Register of Historic Places. While our locals wanted to save the old gas station, they now also want to save the environment.

More people than ever are turning to electric or hybrid vehicles. This is great, but it comes with a learning curve. If you’re one of those drivers of new technology, perhaps you’re interested in more information about regenerative braking. At Jeff’s Auto Repair, we’re here to help you with that as well as with all your brake service and repair needs.

What is it?

Regenerative braking allows your auto to store and use some of the energy that is lost through conventional braking. Conventional brakes work by using hydraulics to press metal components against each other, generating friction that slows the car. This friction produces a great deal of heat. Carmakers design autos to dissipate heat into the atmosphere because elevated temperatures are detrimental to braking system components. Although this helps maintain your ability to stop safely, a lot of energy is wasted through this heat release.

A regenerative braking system offers two advantages. First, it is a necessary means of reducing speed and motion. It’s also designed to harness some of the kinetic energy that is lost through the friction and heat release process. The kinetic energy that is retained is added back to the battery, helping your vehicle maintain its charge longer.

How does it impact the driver?

Perhaps you’re wondering if you’ll notice any difference between your regenerative braking system and your old car with conventional brakes. Yes, you’ll change your braking habits slightly, but you’ll grow accustomed to it on your first drive. When driving a conventional vehicle, you not only let off the gas to slow down, but you also almost always press the brake pedal to stop.

In a car equipped with a regen system, the driver lets off the accelerator and allows the car to slow more naturally. The electric engine reverses itself, sending the kinetic energy harnessed from the slowed roll forward back to a battery for storage. Many drivers develop a new technique called single or one-pedal driving. You’ll only need to take your foot off the accelerator in many cases. The auto will slow enough on its own. If you do need more or quicker stopping power, however, the conventional brakes are always there to help you.
