This report is a summary of the Final Technical Report of the OPTELEC project. The report details the project main contractors and their respective contact details, the project aims and objectives, work programme structure, a summary of the results from each work package, and final conclusions. Further technical information may be requested from the project co-ordinator.

The main technical objectives of the OPTELEC project were to completely re-evaluate the electrical traction system format for a typical passenger vehicle, incorporating state-of-art components, specifically :
- a high efficiency, permanent magnet traction machine, and
- a super-capacitor or flywheel peak power source with energy efficient / low cost power electronic conditioning,
and to research higher integration of the traction system power conversion electronics.

The report concludes that use of a peak power buffer can significantly reduce peak currents drawn from the traction battery of an electric vehicle resulting in a marked improvement in vehicle range and battery lifetime. The test data has also illustrated the potential for a reduction of around 40% of power silicon usage, for a given device current rating, by improved thermal integration of the power stage and cooling system.
