The economic viability of reusing lithium-ion batteries obtained from electric vehicles is highly sensitive to increasing inner resistance and capacity fading of lithium-ion cells. For decision making after removal of the batteries, it is necessary to consider the uncertainties in prediction of the remaining battery lifetime. The purpose of this ar...
Optimum drivetrain design is the key objective for achieving climate and economy improvements in the long-haul industry. The approach introduced focuses on the optimization of electronic component design. Not only are the longitudinal dynamics and the energy consumption included, but a detailed cost model of the components is also applied. The obje...
This paper gives an overview of prices for components of both conventional and electric vehicles, including energy storage, drivetrain as well as interior and exterior vehicle body components. In particular, prices for electric vehicle traction battery packs are analysed, which are estimated to drop remarkably until 2030. In addition, fuel and elec...

Battery aging in electric and hybrid vehicles is a major issue, and one which has to be taken into consideration during all stages of the vehicle lifecycle. It depends on many factors, such as the cell chemistry, the cell design and stress factors as well as the current rate, ∆DOD and temperature. The stress factors have been identified as being cr...
Today’s electric vehicles (EV) use a high system voltage due to the reduction of the appearing current. This results in a much more complex electrical system (high-voltage side: IT topology) compared to that of a conventional car with an internal combustion engine. This can be explained by the need to ensure the safety of the passengers, the mainte...
Motivation Grid energy storage systems have vast potential to enable more renewable and decentralized energy supply in the grid. This has resulted in an increasing demand for more battery energy storage in order to buffer power oversupply or overcome energy shortage. With decreasing costs of lithium-ion batteries, they have become more and more int...
This document presents a tool which assesses the economic performance of different powertrain technologies in various vehicles classes and for several key markets. Vehicles with petrol and diesel engine, vehicles using compressed natural gas (CNG) and electric vehicles are analyzed for being used in Germany, the European Union, the United States of...

The Research Project EEBatt “Distributed stationary battery storage systems for the efficient use of renewable energies and support of grid stability” is a multidisciplinary project run by the TUM’s Munich School of Engineering (MSE).
Combining the strength of 13 chairs and departments of the Technische Universität München, the industry partner VARTA Storage GmbH and the Bavarian Center for Applied Energy Research (ZAE Bayern), a multidisciplinary team of researchers works together on a wide range of issues concerning stationary storage of electrical energy. Driven by the actual evolution in the energy market, the main goal of the project is to investigate, develop and produce a decentralized energy storage device, which ensures that locally generated electrical power can be consumed locally. Based on the actual and expected results for lithium-ion technologies, EEBatt uses Lithium Iron Phosphate (LFP) and Lithium Titanate Oxide (LTO) chemistry for the setup. Together with the KWH Netz GmbH, a regional power supplier company in Haag/Upper Bavaria, the obtained results of the research project will be evaluated and implemented.
The energy turnaround implicates not only a change in the technologies used for energy production, it also means a structural change towards a large number of decentralized time-dependent production facilities. The resulting fluctuations in the power production and imbalanced charging of the power grid make the use of storage technologies essential. To identify and explore possible storage solutions Bayerisches Staatsministerium für Wirtschaft und Medien, Energie und Technologie enables the EEBatt research project.
