Does it make your theoretical range 5% further? 50% further? Even more?Īs you’ve probably already guessed, the effectiveness of regenerative braking varies significantly based on factors including driving conditions, terrain and vehicle size.ĭriving conditions have a large impact. The effectiveness of regenerative braking is a measure of how much it can increase your range. This is where things get really interesting. What should interest us more is the effectiveness of regenerative braking. Someone could be very efficient when they work, but if they only work an hour a day, they probably aren’t accomplishing a lot. This is why only reporting the efficiency of the system doesn’t really mean much. This simply means that 70% of the kinetic energy lost during the act of braking can be turned back into acceleration later. This isn’t going to bump your range from 100 miles to 170 miles. Keep in mind that this 70% does not mean that regenerative braking will give an 70% range increase. This is fairly standard across most electric vehicles including cars, trucks, electric bicycles, electric scooters, etc. Regen usually loses around 10-20% of the energy being captured, and then the car loses another 10-20% or so when converting that energy back into acceleration, according to Tesla. Efficiency of the regenerative braking process varies across many vehicles, motors, batteries and controllers, but is often somewhere in the neighborhood of 60-70% efficient. No machine can be 100% efficient (without breaking the laws of physics), as any transfer of energy will inevitably incur some loss as heat, light, noise, etc. Does it measurably increase your range, or will you not notice much of a difference? Does it waste a lot of energy as heat, or does it turn all of that kinetic energy back into stored energy? Effectiveness, on the other hand, refers to how large of an impact regenerative braking really makes. Efficiency refers to how well regenerative braking captures ‘lost’ energy from braking. Despite sounding similar, the two are quite different. To evaluate regenerative braking, we really need to look at two different parameters, efficiency and effectiveness.

It takes the inefficiency of braking and simply makes the process less wasteful. Since we need to brake often, regenerative braking is the next best thing. Since braking is going to remove energy and require you to input extra energy to get back up to speed, you’d get your best range by simply never slowing down in the first place.īut that obviously isn’t practical. Basically, the most efficient way to drive any vehicle would be to accelerate to a constant speed and then never touch the brake pedal. It doesn’t make electric vehicles more efficient per se, it just makes them less inefficient. It is important to realize that on its own, regenerative braking isn’t a magical range booster for electric vehicles. Then, the next time the car accelerates, it uses much of the energy previously stored from regenerative braking instead of tapping in further to its own energy reserves.

Regenerative braking uses an electric vehicle’s motor as a generator to convert much of the kinetic energy lost when decelerating back into stored energy in the vehicle’s battery. All of that energy was simply lost to the environment.įortunately, we have evolved as a species and developed a better way. Back in the Neanderthal days of internal combustion engine cars, brakes were solely friction based and converted the kinetic energy of the vehicle into wasted heat in order to decelerate a car. Moving vehicles have a lot of kinetic energy, and when brakes are applied to slow a vehicle, all of that kinetic energy has to go somewhere. Join us as we take a deep dive into regenerative braking and its effectiveness in various electric vehicles. But did you know that regenerative braking isn’t only limited to electric cars? These days, you can find it in everything from electric bicycles and skateboards to electric scooters. Ever since the first Toyota Prius rolled off the line over 20 years ago, the concept of regenerative braking has become fairly well-known as a method of increasing range in hybrid and electric vehicles.
