BASED ON 260 MILLION KILOMETERS OF DRIVING CONTROL DATA

Different driving habits and accelerated mode at different rates of energy consumption have an impact on the mileage. In the collection of nearly 200 million kilometers of user driving data, NIU electric re-optimized the electronic control parameter. 150,000 respondents of the operational research successfully fit the parameters of real driving habits, which helped optimize the U1 configuration

BRUSHLESS PERMANENT MAGNET MOTOR

In order to improve the efficiency of the engine, NIU and xiāohào electric jointly researched and developed a new brushless permanent magnet motor. The U1 power system for each component has a precise design, in order to achieve a balance of power and energy efficiency, to ensure that the engine provides enough power while reducing energy losses. Up to 92.6% of the motor conversion rate, efficient energy use, covering greater distances

03

DEVELOPMENT OF FOC CONTROLLER

The independent research and development of the FOC (Field Oriented Control) vector controller with a perfect use of the engine in order to ensure a smooth ride of the U1. Compared to the square wave controller, the vector controller is excellent for linear acceleration. Sophisticated algorithms and precise power setting to "10% turn torque ≈ 10% output torque" ensure maximum power with minimum energy losses

04

EBS SYSTEM

Each brake will produce kinetic energy, and cannot be used effectively as waste. EBS brake energy recovery system, which uses kinetic energy, will be converted into electrical energy, and put again into the lithium battery, which extends the U1's mileage

05

CENTRAL SMART CORE

The U1 central smart core, the central control unit, like a private vehicle analyst that helps to collect data on driving, to make a diagnosis and do the processing. After each ride, with the cloud connection for data analysis, it optimizes the riding experience according to the user's habits

06

MEMS SIX-AXIS MOTION SENSOR

The range of the U1 anti-theft alarm is reduced to an incredible 3 meters thanks to the new MEMS (microelectromechanical system) six-axis motion sensor. The gyroscope is used to determine changes in the acceleration of the vehicle along with GPS positioning, so that the anti-theft protection has been increased by 40%, reaching an incredible 3 meters

Apart from warning of theft, the six-axis sensor can be switched on: Roll (left and right tilt), Pitch (front and rear tilt), Yaw (left and right swing), Dynamic information, if the U1 falls or tilts, you will be notified via the NIU App

BMS BATTERY SYSTEM

As an intelligent controller of all batteries, BMS provides more than accurate calculation of electricity and charge and discharge, and also provides current, voltage, temperature, communication and other 10 kinds of protection to ensure that every part of the battery is stable and functions efficiently. The independent research and development of BMS is more consistent with the lithium battery, to give more security

08

KEYLESS

The U1 have a new keyless start program. When the distance from the U1 is less than 50 meters, you can send instructions to the central control unit via remote control. The remote will turn on the U1 and it will be ready to run. When you ride in the car, press the start button on the vehicle, and you can quickly start U1. Fewer keyholes, more convenient

09

U-FRAME

When you first “meet” U1, the stunning steel of 38mm will leave the first impression. Due to the excellent torsional rigidity and low longitudinal stiffness, the yield strength of up to 235Mpa, K235 steel is often used in building construction, such as shelves, bridges and so on. We used the same choice of steel, K235, for the U1 for its sturdy and practical aesthetic appearance

10

DAYTIME LIGHTS

The U1 is still equipped with daytime running lights and 360 ° lighting system, to reduce accidents around pedestrians and drivers. LED lighting system, and great lighting improve the active safety of the driver; all-weather lighting daytime running lights and U-shaped rear taillights, are nice and elegant, but also greatly enhance the passive safety. Always on your side, the U1 also has a duty to protect people

11

E-MOTOR LOCKER

The new electronic engine lock will be activated when the U1 is locked, and when the vehicle suddenly moves; the electronic motor will be locked and will not be able to turn on, to improve the safety of the U1
