Objective Objectives and content In order to improve both the energy utilisation and acceleration/regenerative braking performance of Electric and Hybrid vehicles, electro-chemical supercapacitors and electro-mechanical flywheels are being developed for use as peak power buffer units. However, to date, it has been assumed that such units would be interfaced directly to the dc link of a conventional traction system via additional standard power electronic converters, which adds complexity and cost, compromises the potential performance improvement, and limits the scope for integrating the power electronics. This proposal will completely re-evaluate the format of the electric traction system for a passenger vehicle, starting with state-of-art components and more specifically: High efficiency permanent magnet traction motor, Supercapacitor or flywheel as peak power source with energy efficient / low cost power conditioning, Fully integrated power electronics unit to function as traction controller / battery charger. Appraisal and analysis of new traction systems and relevant energy management will be carried out. New schemes are proposed for the optimal use of supercapacitors or flywheel in the system and a selection of the most promising Energy Optimised Traction System with the best efficiency and cost saving capability will be done. It will embody a power electronics unit, which is capable of interfacing to state-of-the-art developments in energy storage batteries, flywheel/supercapacitor peak power sources and high efficiency/high performance traction machines. Expected achievements are a gain of up to 25 % in the range of the vehicle for a given stored battery energy, compared with current traction system technology, and 50 % of cost reduction of the power conversion electronics. Components will be designed and manufactured or provisioned using available material processing technology: magnetic motor will be optimised for high efficiency; power electronics unit will be assembled using full integrated process for low cost and volume, improved EMC compliance and energy management. Battery cells supercapacitor elements and flywheel will be adapted to the new system requirement on the basis of existing components in relation with current E.C. supported projects. The Energy Optimised Traction System will be assembled and tested on a test-bench for range and performances evaluation. The partnership combines the expertise of an end user (car manufacturer), technology providers in electrical equipment (batteries, power systems), manufacturing SME's (drives, controls and machine design) and research developers (power electronics, EV systems). This cooperation will guarantee a highly efficient response to the cost and range improvement of the electric vehicle, thereby offering new solutions to EV car and components manufacturers. This is a key element for penetration in the future growing market of electric and hybrid vehicles, highly competitive due to the presence of American and Japanese manufacturers, who are already prototyping new types of vehicles.
