Fellbach ZEROplus

Fellbach ZEROplus

Electromobility in Private Everyday Life

The objective of the Fellbach ZEROplus project is to demonstrate an economic and ecologically meaningful integration of electromobility into the energy management of private households. For this purpose, a group of highly efficient ZEROplus houses will be equipped with house-vehicle energy management systems as well as intelligent quick-charging stations, and this will be scientifically monitored over a period of two years.

Demands and Objectives

For the private use of electromobility, the integration of vehicles into the energy management of residential buildings is of paramount importance. Especially the combination of effective photovoltaic systems and intelligent charging facilities offer great economic and ecological potential. The objective of the Fellbach ZEROplus project is to develop, set up and test such energy management systems and charging stations for a group of seven highly energy-efficient ZEROplus houses. Incorporating charging facilities into the energy management systems will enable financially advantageous and ecological recharging with a maximum amount of self-generated solar electricity. In this way, e-vehicle users do not just save money, but can also actively contribute to the minimisation of peak loads and the stabilisation of the electric grid.

Approach of the Project

The first main focus of the project is the development and testing of the so-called Home-Energy-Management-Systems (HEMS) for the seven ZEROplus houses. The systems will be equipped with an intuitive user interface that has a real time display of the energy flow and allows the regulation of the entire energy management, from the interior climate to the charging of the vehicles. An integrated intelligent algorithm with learning capabilities will also help with the optimisation of the electricity usage taking into consideration energy recovery, economic and ecologic criteria. A second focus of the project will be the development and testing of minimally invasive quick charging points with type-2 plugs that provide a charging performance of 22 KW, that will be installed within the private and semi-private space and are incorporated into the energy management system. The testing of the complete system will be monitored scientifically over a period of two years, so that further optimisation potentials can be researched.
