Optimised Modular Range Extender for every day customer usage (OPTIMORE)
Research Project, 2012 – 2014

Worldwide, there is a strong trend towards highly efficient, low (preferably zero) emission vehicles, i.e. electrical vehicles. In order to facilitate the transition from conventional fuel-driven vehicles towards electrically driven vehicles, there is a short(er) term need for advanced electrical vehicles with range extenders and/or advanced plug-in hybrids. For this purpose, highly efficient, compact, clean and low cost engines are required. Such engines are to provide battery charging over longer trips and/or in areas where electric recharge infrastructure is not (yet) available. Moreover, these engines should be able to significantly improve over future Euro 6 standards for noxious emissions. The OptiMoRE project takes on the challenge to develop and optimise the concept of the fully integrated, range-extended, electrified light duty vehicle. Three different RE concepts will be developed and demonstrated to serve the niches from city vehicles, medium sized passenger cars up to light commercial vehicles. The CONCEPT is based upon: 1. Definition of real world driving conditions (driving cycles and comfort requirements) as a baseline for further optimisation and EV assessment 2. Optimisation of components and the whole RE system regarding emission, fuel consumption, cost, weight and exhaust gas after-treatment 3. Modular setup of an EV concept to fulfil a wide range of customer expectations 4. Advanced control strategies as a key for cost reduction and system optimisation 5. Functional and Electrical safety analysis and concept development to define necessary measures to fulfil and implement ISO 26262 6. Build-up and optimisation of three technology demonstrator vehicles covering EV aspects for delivery trucks, all-purpose vehicles and city cars a) City compact Electric Vehicle, with a rotary engine (2020+) b) A family Electric Vehicle either as FEV or EV-RE with a 3 cyl engine (modular) (2020+) c) Light commercial Electric vehicle 2 cyl engine (2015+)...
