Xiaomi’s electric vehicle has gained popularity due to its reliability and well-designed ecosystem, but many owners are unaware of the hidden potential of their devices. One of the key features that directly affect range and safety is the regenerative braking system. Activation and proper configuration of this mode allow you to return energy to the battery with each braking, significantly extending the battery life.
Turning on recovery is not just a technical manipulation, but a way to make travel more economical and predictable. Kinetic energy, which is normally dissipated uselessly as heat during normal braking, is converted by the engine into electric current. This is especially true for descents and protracted braking before traffic lights, where the efficiency of energy return reaches peak values.
In this article, we will discuss in detail the algorithm for activating the function through the official application, consider the nuances of the system in different driving modes and answer frequent questions. You will learn how to adjust the braking sensitivity to your driving style and why sometimes the system can temporarily shut down to protect components.
Principle of operation and advantages of the KERS system
The technology used in Xiaomi M365, Pro 2 and newer models is based on the properties of a brushless engine. When you pull the trigger or press the brake, the controller switches the engine windings to generator mode, at which point the rotating wheel creates resistance, which feels like braking, while charging the battery.
The efficiency of the process depends on a variety of factors, including current battery charge and wheel speed. Regenerative braking is most active at medium speeds and at a battery charge level below 95-98%. If the battery is fully charged, the system automatically limits the current charge to avoid overcharging and damage to the cells.
⚠️ Attention: On a fully charged battery (100%), the recovery efficiency will be minimal or zero.
This feature not only saves charge, but also reduces wear on mechanical brake pads, and electronic braking takes up to 70 percent of the work to reduce speed in the urban cycle, which is especially noticeable when frequent stops.
Activate the function through the Mi Home app
The main tool for managing the settings of the scooter is the Mi Home mobile application or the specialized Xiaomi Scooter. It is through the software interface that most hidden options are enabled that do not have physical switches on the device body.
First, you need to connect the scooter to your smartphone via Bluetooth, make sure the device is nearby and the screen displays the status "Connected." After that, go to the control menu of your vehicle, usually the three dots in the upper right corner or the settings button in the profile of the device.
- 📱 Open the Mi Home app on your smartphone.
- 🔗 Select your electric scooter from the list of devices in the main menu.
- ⚙️ Click on the settings icon (cog) in the upper right corner of the screen.
- 🔋 Find the item "Regenerative braking" or "Energy Recovery».
In the menu that opens, you will be asked to choose one of the available modes of operation. Depending on the model and firmware version, the options may be called Low, Medium and High, or have descriptive titles like Comfort and Standard.
Once you have selected the desired setting, be sure to press the Save or Apply button. The scooter can emit a short beep confirming the successful recording of the new settings in the controller's memory.
Adjustment of braking intensity levels
Xiaomi models offer varying braking forces to adapt vehicle behavior to road conditions, and understanding the difference between levels is critical for safe and comfortable driving, especially for beginners.
The low level (Low) provides a very smooth deceleration that is almost not felt by the passenger, ideal for driving on slippery roads, wet pavements or pavers, where a sharp locking of the wheel can lead to skids.
High levels (High) create a tangible resistance immediately after the gas pedal is released. The scooter slows down very intensely, almost like when you press the mechanical brake, which allows you to travel long distances without frequent use of levers, but it requires addiction.
The mid-range mode is a compromise solution that combines energy recovery efficiency with comfort, and it is recommended in most urban situations to balance the savings of charge and smoothness.
Comparison of recovery operation modes
To make it easier for you to decide on the settings, we have prepared a summary table that describes the behavior of the scooter in different modes, which will help you choose the best option for your driving style.
| Parameter | Low (Low) | Medium (Medium) | Tall (High) |
|---|---|---|---|
| Braking force | Minimum | Moderate. | Maximum |
| Saving energy | Low. | Medium | Tall. |
| Comfort of driving | High-pitched | Optimal. | It takes habits. |
| Risk of skidding | Low. | Medium. | Tall on slippery |
When choosing a mode, consider not only your preferences, but also the technical condition of your Xiaomi. On older batteries with high internal resistance, recovery efficiency in High mode may be lower than expected due to the limitations of the BMS (battery management system).
Diagnostics and troubleshooting
Sometimes users are faced with a situation where recovery stops working or is not working smoothly, which can be caused by software failures, operating features or technical problems, and in most cases, the situation can be corrected independently.
One common reason for not braking is the temperature of the engine or battery. If you just completed a long trip or, conversely, went out into the cold, the system may temporarily limit the functionality to protect the components.
- 🔋 Check the charge level: above 98% recovery is not working.
- 🌡️ Make sure the battery temperature is in the operating range (0...40).°C).
- 🔄 Reboot the scooter by turning off and on the power.
- 📲 Update the firmware through the app to the latest version.
⚠️ Warning: If you hear a strong crack or feel jerks during active braking, stop using high recovery mode immediately.This may indicate problems with bearings or controller.
It is also worth checking the integrity of the wiring going from engine to controller, oxidation of contacts or damage to insulation can lead to incorrect operation of the Hall sensors, which knocks down the braking algorithms.

Effects of recovery on battery life
There's a myth that using recuperation to do a lot of damage to the battery. BMS-controllers in Xiaomi devices strictly monitor charging current parameters. The system will not allow the battery to supply current exceeding safe values, even if the engine generates more power.
However, constant maximum recovery on long descents can lead to heating of the battery cells. Lithium-ion batteries are sensitive to overheating, so in hot weather it is recommended to use moderate settings.
On the other hand, the understressing of cells in active discharge is also harmful, and recovery helps to keep the voltage in the packet from falling too deep with frequent accelerations, which prolongs the total life of charge-discharge cycles.
Safe operation tips
Despite the effectiveness of electronic braking, it is not possible to rely solely on it. Mechanical brakes (disc or drum) remain the main means of emergency stopping. Recovery should be considered as an auxiliary system for planned speed reduction.
When driving on wet pavement, leaves or sand, let the gas flow smoothly abruptly. In High mode, instantaneous wheel locking can lead to loss of control and fall. Always predict the road situation in advance.
Check the mechanical brakes regularly, and because recovery reduces the load on the pads, owners often forget to maintain them, which can lead to souring of the machinery or complete failure at a critical moment.
