The TELL project addresses the optimisation and large-scale manufacturing of low and medium voltage electric powertrain solutions, with focus on high efficiency, compact packaging and low cost. Three main applications are targeted:
• Small-to-medium segment electric cars
• Hybrid electric cars with a low voltage add-on electric propulsion system
• The lightweight urban mobility sector, e.g. electric quadricycles
The project aims
• to develop innovative, integrated and modular powertrain solutions targeting the 2030 requirements of urban electric vehicles across different brands and regional markets
• to enhance efficiency, range, reliability, safety, dependability, by applying emerging semiconductor technologies and a low-voltage approach
• to demonstrate the TELL powertrains within an innovative electric vehicle architecture developed in previous projects and featuring high degree of security, user friendliness and acceptance
• to develop production methods targeting high-volume automotive-quality manufacturing at affordable cost
The TELL powertrains will be demonstrated on two electric vehicle platforms: i) a four-wheel-drive vehicle operated at a nominal voltage of 100 V by a Si MOSFET based inverter; and ii) a two-wheel-drive vehicle operated at a nominal voltage of 48 V by an inverter based on GaN and Silicon semiconductor technology, including a comparison of both sources regarding usability in the near future.
