Background & Policy context

In order to guarantee the success of electric vehicles as main means of transport, energy storage systems should also be addressed.


iZEUS (intelligent Zero Emission Urban System) develops concepts and application examples for the integration of electromobility into private transport and urban commercial transport. The aim is to develop a uniform traffic and energy management concept, which will be tested and demonstrated on the basis of fleet tests with a significant number of vehicles. Research priorities include, for example, innovative billing and fleet management systems as well as decentralised energy and charging management using stationary storage facilities for the improved integration of renewable energy sources and for the stabilisation of distribution networks.


1. Creating the incentive signal: To create the incentive signal, a simulation is made of possible future energy situations taking into account framework conditions like the installed power of fluctuating energy producers and fuel prices derived from existing energy scenarios. A marginal cost-based tariff for load and feed-in management is calculated using the agent-based market equilibrium model PowerACE. Moreover, a field trial evaluation, the effect of the signal with regard to the integration of renewable energies is analysed and assessed in a simulation environment.

2. Developing/Testing hardware for electric vehicles: Deriving decisions about charging/feed-in behaviour and grid support functions from the grid situation monitored by the vehicle and an energy-sector incentive signal given by specialised algorithms that still have to be developed.

3. Deriving ICT products that conform with customer requirements: Designing and further developing methods to assess the acceptance of ICT products. Customer acceptance is studied based on two main pillars

3.1. Accompanying the field tests in the project, especially the vehicle fleet provided by Daimler

3.2. Representative survey of population

The project has shown that electromobility can work in everyday urban life. iZEUS takes electromobility a big step forward with a whole bundle of solutions for fleet and energy management, mobility and billing services as well as network-friendly charging strategies.

Moreover, a bi-directional charger with integrated function for real-time analysis of distribution networks was developed and tested with an Opel Meriva electric vehicle at the Energy Smart Home Lab of the KIT. Due to the fluctuating feed-in of renewable energies into the electricity grid, such an intelligent, two-way information exchange during the charging process is necessary to avoid bottlenecks in the distribution network. Using a stationary lithium-ion battery storage device, renewable energies are to be integrated into the energy system in the future and the regulating power, voltage and load in the grid are to be controlled independently. Thanks to the efficiency of the system, charging costs for users can also be reduced and emissions from electric mobility avoided through energy savings.
