The Mini QED is a demonstration vehicle that showcases the Quad Electric Drive, a four wheel motor in wheel drive, plug-in electric vehicle, developed by PML Flightlink and its partner Synergy Innovations and unveiled at the British Motor Show. The QED has an all-electric range of 200-250 miles (333-417 km) and has a total range of about 932 miles (1,500 km). The car accelerates from 0-60 mph in less than 5 seconds. Two vehicles have been produced to demonstrate what can be achieved using the companies in wheel motor technology.
Some key features are:
The PML eWheel permanent magnet wheel motor is designed to be rugged and flexible. Based on 5 years of evolution, the eWheel offers exceptional efficiency, coupled with a high power to weight ratio that makes it the ideal solution for battery powered equipment. Extensive attention to detail has been placed in the bearing, sealing and weather proofing arrangements to provide the eWheel with enough build quality to withstand arduous environments. The design features include rugged oversized taper roller bearings, fully waterproof to IP 65, high torque overload rating for fast acceleration, over-temperature thermistors fitted and smooth 12 step commutation for smooth high power performance

Anti-skid - Dynamically monitors wheel to detect skid onset. Manages state to obtain maximum non-skid torque from wheel in either acceleration or braking modes.
Traction control - Dynamically distributes torque when any wheel is in skid management mode to obtain optimum tractive effort and stability.
