UQM Technologies will supply PowerPhase electric propulsion systems as part of an Audi test-fleet build and vehicle development process for the Audi A1 e-tron electric car.
The UQM PowerPhase engine range is a lightweight electric drive motor and controller. This power-dense, brushless, permanent-magnet engine range can be supplied with up to 300 Nm of peak torque and 125 kW of peak power. The controller features CAN bus, serial communications and diagnostic capability.
In addition to a full line of electric propulsion systems, UQM recently completed the validation of its volume production lines with annual capacity of 40,000 units.
The Audi A1 e-tron has a range of more than 50 kilometers (31 miles) in city traffic and a peak power output of 75 kW (102 hp). A compact internal combustion engine recharges the battery when its energy is depleted.
A small, single-rotor Wankel engine in this near-series vehicle increases the range in exceptional circumstances. This “range extender” powers a generator that produces 15 kW of charging power. If the range extender is used to recharge the battery, the A1 e-tron can cover an additional 200 kilometers (124.27 miles) of range. According to a draft standard for the computation of fuel consumption for range extender vehicles, this represents a fuel consumption of 1.9 l/100 km (123.80 mpg) – a CO2 equivalent of only 45 g/km (72.42 g/mile). Top speed is 130 km/h (80.78 mph).
