Owners of the latest Xiaomi SU7 electric vehicles and car enthusiasts often encounter a setup called “energy recovery,” which directly affects how the car behaves when the accelerator pedal is released. Understanding how the system works not only saves battery life, but also makes driving more predictable.
Recovery is the process of converting the kinetic energy of a moving car back into electrical energy to charge the battery, so when you take your foot off the gas pedal, the electric motor goes into generator mode, creating braking torque, and that's the intensity of this process, and that's regulated by the degree of recovery in the menu of the multimedia system.
Importantly, misconfiguring this setting can cause discomfort to passengers or even lead to an emergency if the driver is not used to a sharp deceleration. In this article, we will take a closer look at how modes differ, how they affect real range, and why Xiaomi offers flexible settings for different driving scenarios.
Recovery in Xiaomi electric vehicles
The fundamental basis of recovery in the Xiaomi SU7 is to invert the electric motor. Unlike traditional ICEs, where the kinetic energy is simply dissipated as heat in the brake pads, here it accumulates. The battery management system (BMS) takes this current and distributes it safely to the cells.
The degree of recovery determines how aggressively the motor will resist the inertia of the car. The higher the value, the stronger the feeling of "tension" when releasing the accelerator pedal, which allows in many situations to do without using the main braking system, which significantly prolongs the life of brake discs and pads.
However, the recovery efficiency decreases if the battery is fully charged (usually above 95-98%) or if it is too cold, in which case the system will automatically reduce the degree of braking by the engine, relying on hydraulic brakes for safety.
⚠️ Warning: Don't expect to stop the car completely by recuperating in an emergency.The hydraulic braking system must always be ready to work, especially on slippery roads or with a sharp decrease in speed.
The HyperOS technology stack in the car allows you to fine-tune this process by adapting it to your driving style. It's not just fixed modes, but a complex system that takes into account the current speed, the angle of the road and the temperature of the components.
Recovery modes: Low, Medium and High
Xiaomi’s vehicle interface typically has three basic levels of customization, each of which dramatically changes the behavior of the car. The choice of the right mode depends on the driving conditions and the habits of the driver.
Low provides behavior as close as possible to a classic combustion engine car. The car continues to run inertia for quite a long time, barely slowing down. This is ideal for road trips or for those who get rocked in sharp electric cars.
Medium is the middle ground, providing a noticeable slowdown but not causing a sharp jerk, a mode that is most often recommended for mixed driving cycles in and out of the city.
High level (High) or "One-Pedal" mode (one pedal) allows you to almost completely abandon the brake pedal in urban traffic. When you release the accelerator, the car quickly loses speed, up to a complete stop.
How does One-Pedal work?
- 🚗 Low: Ideal for country roads and getting used to electric cars.
- 🏙️ Medium: The optimal balance for daily driving in moderate rhythm.
- ⚡ High: Maximum energy savings in dense urban traffic.
Switching between modes is instantaneous and displayed on the dashboard. The driver can change the settings on the move, but it is recommended to do this only on straight sections of the road to avoid losing concentration.
Effect of degree of recovery on range
The main question that owners are concerned about is: How much does the recovery setting affect the real range? The answer is unequivocal: the impact is significant, especially in urban conditions. The higher the degree of recovery, the more energy returns to the battery with frequent acceleration and braking.
In an urban cycle where stops at traffic lights and traffic jams occur constantly, a high level of recovery can increase the actual mileage on the road. 10-15%. The car is constantly recharged from its own braking, and on a track where speed is constant and braking is low, the difference between modes becomes minimal.
It's important to remember the physical law of conservation of energy, and that's because recovery doesn't create energy out of nowhere, it just returns some of what was spent on acceleration, so a "gas to floor - braking sharp" driving style is going to be less effective than a smooth, predictive driving style, even at maximum recovery.
The Xiaomi Pilot system can also automatically adjust the degree of recovery depending on the selected driving mode (Eco, Sport, Comfort).In Eco mode, the system seeks to maximize energy return, while in Sport, dynamics and responsiveness become the priority.
Setting up options in the HyperOS Car menu
To change the degree of recovery in the Xiaomi SU7 car, you need to consult the central display.The interface is built logically, but it may take time for the beginner to find all the hidden settings.
First, go to the main car settings menu, usually the gear icon or car card icon in the bottom menu, then select the section responsible for driving or driving. In some versions, the path may look like Settings → Driving → Recovery.
In the menu that opens, you'll see a slider or a selection of three preset modes, and some firmware versions allow you to adjust the recovery force more flexibly, giving you a percentage of braking force.
💡
Use Xiao AI to quickly change your settings, just say, "Make recovery stronger" or "Set recovery low."
☑️ Set-up of recovery
After the change in settings, it is recommended to do several test accelerations and braking to get used to the new dynamics.A sharp change in behavior of the car can surprise the driver at the first moment.
Comparison of braking mode characteristics
To better understand the difference between modes, we'll use a comparative chart to help you visualize what to expect from each level of customization in different settings.
| Parameter | Low (Low) | Medium (Medium) | Tall (High) |
|---|---|---|---|
| Pedal sensation | Smooth, like the ICE. | Moderate deceleration | A sharp, strong tension |
| Savings in the city | Low. | Medium | Maximum |
| Comfort of passengers | High-pitched | Medium. | Low (possible motion sickness) |
| Wear of brakes | Standard. | Reduced | Minimum |
As you can see from the table, the trade-off is always between comfort and efficiency. For family trips with children or people prone to motion sickness, it is best to avoid High mode.
Adaptive recovery and intelligent systems
Xiaomi’s current electric vehicles are equipped with advanced adaptive recovery systems, in which the car decides how hard to brake the engine, based on camera and radar data.
If there's an obstacle or a slow-moving vehicle ahead, the system enhances recovery in advance, alerting the driver and saving energy. If the road is free, the drag decreases, allowing the car to roll. This requires complex AI algorithms.
The driver can combine manual adjustments with adaptive functions, such as setting a baseline to Medium, but allowing the system to temporarily increase braking as it approaches intersections, creating a feeling of a "live" car that anticipates the pilot's wishes.
⚠️ Attention: Adaptive recovery may not work properly in heavy snow, fog or sensor contamination, and in such conditions, the system may warn of a temporary shutdown and transition to standard mode.
The constant update of Xiaomi HyperOS software improves the algorithms of these systems, so it is recommended to regularly check for updates in the Settings menu → System → Software Update.
Frequent questions and technical nuances
Owners often ask questions about the durability of the battery when using active recovery. Permanent micro-charges with high currents can theoretically affect the chemical composition of the cells, but the BMS system in the Xiaomi SU7 strictly controls this process, avoiding overheating and overloading.
Another important aspect is the recovery operation at subzero temperatures, and in winter, the energy recovery efficiency is reduced because lithium-ion batteries don't take charge well in the cold, and the car will brake weaker until the battery warms up.
💡
The optimal strategy is to use the high level of recovery in the summer in the city and switch to low in the winter or on the track for comfort.
Understanding these nuances will help you make the most of your electric vehicle, ensuring safety and extending the life of all vehicle nodes.
