At the core of the NQi-Series sits the BOSCH-developed 1500W Motor. The NIU proprietary Field Oriented Control* delivers the ultimate driving experience.
This mash-up of technology and hardware strikes the perfect balance of performance and power consumption.
*Field Oriented Control is abbreviated as FOC below.
Extending the ride and performance
In real-time, the FOC is monitoring the overall electricity demand on the system so that the BOSCH motor performs at a peak level while efficiently using all resources available.
To enhance overall vehicle performance, the Electric Brake System (EBS) and FOC optimize power conservation and output, effectively recycling power during certain periods of braking and limiting power output during select periods of acceleration.
We have been able to reduce braking distances by up to 60% and recycle 6% of the battery capacity back into the system through our intelligent braking system.
We have collaborated with BOSCH to develop the NQi-Series motor. With 65 Nm of torque at its disposal, the NQi-Series provides the “get-up-and-go” you need to feel safe on a car dominated road. Couple this with a 1500W power output to easily reach a top cruising speed of 45km/h.
BOSCH’s state-of-the-art motor technology is a key component in optimizing energy efficiency by reducing motor abrasion and power wastage that can be found in a typical motor. Compared to typical motors under the same driving conditions, the NQi-Series motor is at least 10% more efficient.
The NIU FOC (Field Oriented Control) system was built in collaboration with BOSCH to create a state-of-the-art power train. Striking a fine balance between performance and energy consumption, the FOC is key in balancing range and speed.
You can think of the FOC as the brain controlling the motor in real-time. It recognizes your riding conditions and instantly calls on the motor for optimal performance. The FOC measures scooter diagnostics, which you as a driver cannot see, and then decide how to respond to your driving inputs.
Our FOC taps into the performance of a vector controller, which is far superior to the standard square-wave controllers on the market. When people get off the bike after their first or fiftieth ride, they always say, “I cannot believe how smooth this scooter is.” It’s all because of the FOC.
The NIU brakes are engineered from a high-manganese steel composite, lubricated with BOSCH brake fluid, and equipped with a threaded brake line to extend the life of the entire system.
Not only does the EBS make your ride more safe, it also recycles energy back into the system. On average the EBS provides an additional 6% of battery power, or 4km of riding range.
