EV Recuperation: Everything You Need to Know

Today, almost all electric vehicles feature recuperation technology. However, many EV owners are unfamiliar with how it works and how they can maximize energy savings through it.

We’ll simplify the concept of recuperation in this article, discuss the benefits it brings to EV drivers, offer actionable advice for optimizing its use, and feature a selection of EVs with exceptional recuperation systems.

We hope this article provides valuable insights to enhance your daily EV experience.

Most electric motors in EVs utilize the recuperation mechanism. But how does it work? In simple terms, it functions as follows: when you lift your foot off the accelerator pedal, the electric motors begin to resist the rotation of the wheels. This resistance creates two key benefits of recuperation: first, it generates electricity that is sent back to the battery, and second, it slows the car down. In vehicles with a powerful recuperation system, the car can even come to a stop without using the traditional brakes!

When you press the brakes, the electric motor’s resistance increases, generating more energy. However, this also means a shorter stopping distance, which can limit the amount of energy recovered since the recuperation process is cut short. Once the car comes to a complete stop, recuperation ceases entirely.

Another interesting point is how motor configuration affects recuperation: EVs with multiple motors deliver a stronger recuperation effect than those with just one motor. As a result, dual or multi-motor vehicles are more efficient at recovering energy than single-motor models.

The key takeaway is this: the less you rely on the accelerator pedal and avoid coming to a full stop, the more energy you can conserve. We’ll delve into this concept further toward the end of the article.

Now, let’s explore the benefits of using the recuperation system on your EV.

Illustrated Process of Recuperation

As we mentioned earlier, recuperation offers some significant advantages that traditional petrol-powered cars cannot provide. Let’s take a closer look at these benefits:

Saving Energy: The primary advantage of recuperation is the ability to return energy directly to your battery. Imagine gaining 20% or more battery charge after a long downhill drive simply by not using the accelerator pedal — isn’t that a great way to maximize efficiency and range?
One-Pedal Driving: In city driving, where constant braking is common with petrol-powered vehicles, strong recuperation becomes an excellent ally. With an effective regenerative braking system, you can often drive using just the accelerator pedal. The powerful deceleration from recuperation handles most of the braking, leaving the brake pedal necessary only for emergencies.
Reduce Brake Maintenance Costs: As mentioned earlier, regenerative braking significantly reduces the need for using traditional brakes. While this enhances comfort and convenience, it also saves money. With less frequent use, brake pads and other components in the braking system last much longer, lowering maintenance costs compared to vehicles without recuperation systems.
Experience Smoother Braking: Compared to traditional braking systems, regenerative braking offers a smoother and more comfortable experience for everyone. Its predictability allows you to anticipate the braking force applied when you lift your foot off the accelerator pedal. Additionally, many EVs allow you to adjust the level of recuperation, enabling you to fine-tune the braking to achieve an even smoother and more tailored driving experience.
Reduce Energy Waste: Recuperation benefits both you and the environment. Every mile you save using recuperation means less time spent charging your vehicle at a station and less electricity consumed overall. This not only reduces your energy costs but also minimizes the environmental impact of charging your EV.

We hope you now have a better understanding of what recuperation is and the benefits it provides to EV drivers. Let’s explore some practical tips on how to maximize the use of your recuperation system:

Plan Your Route Wisely: If possible, plan your route to include downhill sections. This is the best way to save a significant amount of energy. The more you descend without using the accelerator, the more power your EV will recover. In some cases, this could potentially supply sufficient energy to reach your destination without the need for a charging stop.
Adjust Recuperation Settings: Many modern EVs allow you to adjust the level of regenerative braking. To maximize energy savings, select a stronger recuperation level in the settings. This will enable the electric motors to recover as much energy as possible. However, keep in mind that stronger recuperation also means more pronounced braking. Be sure to adjust the settings to suit your driving preferences and specific needs.
Avoid Sudden Stops: To maximize energy recovery through recuperation, try to minimize the use of the brake pedal, especially if your EV supports “one-pedal” driving. Instead, allow the regenerative braking system to handle most of the deceleration. Use the traditional braking system only when a full stop is required.
Limited Recuperation: Recuperation in EVs is most effective when the battery has charging capacity and the vehicle's systems, particularly the motors and battery, are operating at optimal temperatures. Full battery charge and cold operating conditions can significantly diminish regenerative braking strength and efficiency.
Maintain Your EV’s Technical Condition: The proper functioning of your recuperation system depends on your EV's overall technical condition. Regularly inspect the electric motors and battery to ensure there are no issues affecting their performance. Even something as simple as low tire pressure can impact the efficiency of the recuperation system, so make sure to keep your tires properly inflated as well.

There's no difference between recuperation and regenerative braking in the context of electric vehicles. They are two terms that refer to the same process: capturing kinetic energy during deceleration and converting it into electrical energy to recharge the battery.

Regenerative braking is the more common and widely understood term, especially in North America. It clearly describes the process of "regenerating" energy.
Recuperation is often used in Europe and other parts of the world. It emphasizes the "recuperating" or recovering of energy that would otherwise be lost.

No, recuperation doesn't replace traditional brakes in EVs. While efficient for smooth slowing and energy capture, it's insufficient for emergency stops, low speeds, and as a primary safety system. Traditional friction brakes provide the necessary stopping power in critical situations, working in conjunction with recuperation.

One-pedal driving lets you control acceleration and deceleration primarily with the accelerator pedal. Pressing it accelerates; releasing it engages regenerative braking, slowing the car and recovering energy. In many cases, fully releasing the pedal brings the car to a complete stop. This increases efficiency, smooths driving, and reduces brake wear.

Regenerative braking can help keep the battery within a healthier state of charge. While not the sole factor affecting battery lifespan, it contributes to potentially longer battery life by optimizing battery usage and reducing stress. Think of it as giving your battery frequent "top-ups," which can be better for its long-term health than constantly deep-discharging it.

When an EV battery is full, regenerative braking can no longer send energy back to it. Consequently, the level of regeneration is reduced or disabled, and the car relies more heavily on traditional friction brakes for deceleration. This blending of braking systems ensures smooth stopping while protecting the battery fr om overcharging.

Recuperation is no longer just a feature; it's fundamental to the modern EV driving experience, enhancing both energy efficiency and ride comfort.
