Introduction To One Pedal Driving
Of the many benefits offered by electric vehicles (EVs), one-pedal driving often goes relatively overlooked. Since EVs don’t use traditional powertrains, some models are configured to take advantage of their simplicity. One-pedal driving uses regenerative braking, which is common on many EVs and hybrids, such as those made by Tesla and Chevy, to recapture energy usually lost during braking.
How One-Pedal Driving Works
One-pedal driving, commonly used in EVs, uses only the accelerator pedal. It’s touted as both an easier way to drive and a way to maximize electric range, with regen capabilities helping extend your EV’s efficiency. Though it can take some time to acclimate, it will only become more common as more EVs are sold. Auto manufacturers and experts recommend practicing one-pedal driving in a parking lot before attempting it in traffic. Remember, the brake pedal is still there if you need to stop quickly.
Activating One-Pedal Driving In Your EV
To use one-pedal driving, first turn the feature on, which may vary by make and model but is usually controlled by a button near the gearshift or through the drive mode settings. When the feature is on, it will work in both drive (forward) and reverse. Ensure to check with your manufacturer for exact instructions.
Operating One-Pedal Driving
Press the accelerator to drive as usual, or engage cruise control for a steadier speed. To slow down gradually, lift your foot to remove pressure from the accelerator, allowing the vehicle to coast. To slow quickly,
Safety Features
With one-pedal driving engaged, the car’s brake lights will illuminate when the car is slowing down. This ensures that drivers behind you are aware that you are decelerating, especially when you coast or prepare to come to a complete stop.
Benefits of One-Pedal Driving
Though getting used to one-pedal driving will take some practice, it’s worth it. According to the U.S. Department of Energy, this system helps maximize an EV’s range and prolongs not only battery life but also brake life, as you aren’t using the brakes to slow the car. Using one-pedal driving can add about 13 miles to an EV’s range.
What is Regen or Regenerative Braking?
Regenerative braking is a key feature in electric vehicles that allows them to recover energy during deceleration and braking, which would otherwise be lost as heat in traditional vehicles. By converting the vehicle’s kinetic energy back into electrical energy and storing it in the battery, regenerative braking enhances efficiency and increases the overall range of electric vehicles. This technology not only contributes to a more sustainable driving experience but also improves control and responsiveness, providing drivers with a smoother and more intuitive driving feel. Additionally, regenerative braking reduces wear on traditional friction brakes, leading to longer-lasting brake systems and lower maintenance costs over the vehicle’s lifespan.
When Not to Use One-Pedal Driving
However, one-pedal driving should not be used when towing or carrying a heavy load, on slippery surfaces, driving down steep hills, or when you need to come to a complete stop. One-pedal driving can be highly convenient and efficient in many driving scenarios, particularly in electric vehicles equipped with regenerative braking and coast features. However, there are specific situations where it is advisable to avoid using this feature, such as when driving a Tesla on a steep hill:
Towing or Carrying a Heavy Load
When your vehicle is towing a trailer or carrying a significant amount of weight, the braking dynamics change. The added mass can affect how the vehicle responds, and relying solely on regenerative braking may not provide the necessary stopping power, potentially compromising safety, especially if the vehicle cannot come to a complete stop.
Driving on Slippery Surfaces
On surfaces with reduced traction, such as ice, snow, or wet roads, the sudden deceleration from regenerative braking could lead to skidding or loss of control. Conventional braking allows more gradual and adjusted deceleration, reducing the risk of slipping.
Driving Down Very Steep Hills
While regenerative braking can help control speed when driving downhill, relying entirely on one-pedal driving may not be sufficient for very steep or prolonged descents, requiring the use of the brake pedal to come to a complete stop. Prolonged regenerative braking can also cause the system to overheat or become less efficient. Using engine braking (in a traditional vehicle) or traditional brakes in conjunction with regenerative braking will offer more effective speed control and safety.
Can eMotorbikes Use One Pedal Driving?
Not yet! But perhaps soon. LiveWire have patented an idea to introduce it into electric motorbikes. This will allow people to get the benefits of one pedal driving on a motorbike. The idea is still just speculation as nothing official has been said but it will be interesting to see how the technology develops. This combined with the Polestar 10 minute charging technology might lead to interesting things in the future!
Conclusion
As more EVs hit the market, one-pedal driving will become a standard feature that drivers will appreciate for its ease and efficiency, especially in Chevy and Tesla models and perhaps soon emotorbikes. When uses one pedal driving, take your time as practice makes perfect, so get used to this beneficial feature in a safe environment before using it on busy roads.
One-Pedal Driving FAQs
What is One-Pedal Driving and How Does It Work?
One-pedal driving is a feature in electric vehicles (EVs) that allows drivers to accelerate and decelerate using only the accelerator pedal. When you lift your foot off the pedal, the car uses regenerative braking to slow down and can even come to a complete stop without the need to touch the brake pedal. This driving style can make driving more intuitive and can enhance the efficiency of your electric car by capturing energy that would otherwise be lost during braking.
What are the Benefits of One-Pedal Driving?
The benefits of one-pedal driving include increased efficiency and energy recovery through regenerative braking. This can extend the range of your electric vehicle (EV). It can also reduce wear and tear on the brake pads, since friction brakes are used less frequently. Moreover, many drivers find it more convenient and straightforward because it requires fewer inputs, thus potentially reducing fatigue during long drives.
How Do I Activate One-Pedal Driving in My EV?
Activating one-pedal driving generally involves changing the drive mode settings in your EV. For instance, in a Tesla Model 3 or a Chevy Bolt, you can navigate to the settings on the display screen and select the specific mode for one-pedal driving. Make sure to consult your vehicle’s owner manual for precise instructions, as the process may vary by manufacturer and model.
Do All EVs Offer One-Pedal Driving?
Not all electric vehicles (EVs) come equipped with one-pedal driving capabilities. However, many modern EVs such as Tesla models, the Chevy Bolt, and others do offer this feature. It’s essential to check the specifications of the electric car you’re interested in to confirm whether it includes one-pedal driving mode.
Can I Use Cruise Control with One-Pedal Driving?
Yes, you can use cruise control with one-pedal driving in many electric vehicles. However, the specifics may vary depending on the make and model of your EV. Here are some key points to consider:
Compatibility: Not all EVs support the use of one-pedal driving and cruise control simultaneously. Check your vehicle’s manual or consult with the manufacturer to ensure compatibility.
Functionality: When cruise control is activated, some EVs may temporarily disable one-pedal driving features such as regenerative braking. This is because cruise control typically maintains a constant speed, and regenerative braking could interfere with this function.
Safety Features: Modern EVs often come equipped with advanced driver assistance systems (ADAS) that work in conjunction with cruise control. These systems can include adaptive cruise control, which adjusts your speed based on traffic conditions, and may still utilize regenerative braking to some extent.
Driver Preferences: Some drivers prefer to disengage one-pedal driving when using cruise control for a smoother experience, especially on highways or during long trips.
To summarize, while it is possible to use cruise control with one-pedal driving in many EVs, it’s essential to understand how your specific vehicle handles the integration of these features. Always refer to your vehicle’s user manual for detailed instructions and safety guidelines.
