The major criticism in customer surveys on Fully Electric Vehicles (FEV) is the strongly limited driving range compared to vehicles with a conventional internal combustion engine. The OpEneR project addresses this so called „range anxiety“ and aims to unlock the FEV market by increasing the driving range. The approach is not the enhancement of battery technologies, but the development of an intelligent energy management and recovery system. This system will provide advanced driver support based on a networked architecture comprising battery, e-machine, regenerative braking, satellite navigation, dashboard displays and predictive cooperative information. An advanced vehicle stability controller and environmental sensing guarantee the safety of the driver. OpEneR brings a new integrated approach where all available and emerging information is used to generate safe and efficient predictions. The project results will be demonstrated in two fully operational FEV in real world conditions.
