Renault Twizy Upgrade Project

Integration of High-Frequency Combined Winding Induction Motor & VFD Drive Technology

Stock Configuration

Factory induction motor setup with standard controller, limited range, and restricted thermal performance at peak loads.

Dynamometer & Road Testing

Real-world testing showcasing high-frequency motor response, smoother acceleration, and extended driving range.

Advanced Stator Technology

Custom multi-pole high-frequency stator winding design optimizing field weakening modes without rare-earth magnets.

Drive System Efficiency Comparison

Stock Motor System Efficiency (Peak) ~65%

ASPP High-Frequency Drive Efficiency (Peak) 92%

Technical Specifications & Comparison

Parameter	Stock Renault Twizy 80	ASPP Modernized Version	Improvement
Motor Type	Standard Induction Motor	High-Frequency Combined Winding	Optimized Electromagnetic Design
Peak Torque	55 Nm	83 Nm	+51%
Top Speed	90 km/h	90 km/h	0
Energy Consumption	~63 Wh/km	~48 Wh/km	-23% Energy Saved
Range per Charge	~70 km	~104 km	+48,5 % Range
Cooling System	Air Cooled	Enhanced Passive Thermal Dissipation	Reduced Heat Loss

The calculations are based on a five-year-old battery and a chassis with the specifications of a used Renault Twizy—given that the actual Twizy, prior to modification, had a maximum range of 70 km.

____________________

Over 20% more range from the original motor – and that’s just the start.

Our ASPP upgrade pushes your Twizy to 18 kW and stretches every kilometre, even with a 5‑year‑old pack (typical annual loss: 2‑5%).
Fit a new battery and you’ll multiply that gain by up to 25% more – because we’ve eliminated the motor’s inefficiency, so the battery’s true capacity finally shines.
Test it in Monaco – and watch the reserve stay above 10% after 100 km.

Real Road Testing with Range more as 100 km

Real‑world trial: our ASPP‑upgraded Twizy covers 100 km on a 5‑year‑old battery – and still comes back with >10% charge. Standard range drops significantly with age, but our motor control technology squeezes every watt out of aged cells. See for yourself – test it on your routes and compare the remaining range.
