BFH-CSEM Energy Storage Research Centre

The BFH-CSEM Energy Storage Research Centre develops solutions for the energy production of tomorrow. These solutions make it possible for renewable energies from decentralised production to be integrated into the supply grid, and to replace fossil fuels for transportation. The objective is to better exploit the potential of sustainable energy sources such as photovoltaic and wind power.

Current projects

«SwissTrolley plus»

The «SwissTrolley plus» is a flagship project supported by the Swiss Federal Office of Energy and aims to build a 100% electromobile vehicle made in Switzerland with sustainable components and controls. Its high-performance traction battery permits operation without a trolley system. Moreover, up to 15 percent of energy can be saved through regenerative braking. As a result, the «SwissTrolley plus» enables more cost-efficient, reliable and flexible operation of trolleybus lines.

Prosumer lab project

The Prosumer lab project is a pilot and demonstration project financed by the Swiss Federal Office of Energy (SFOE) and the industry partner BKW Energie AG. The main priority is a test installation, which is currently under construction in the laboratory of the BFH-CSEM Energy Storage Research Centre. The installation is designed to replicate in a reproducible way the electrical energy flows in a single or multiple dwelling house using photovoltaic and battery storage systems. In this way, system components such as energy managers, power inverters and battery storage systems can be compared and tested.



The team at evolaris aviation, a spin-off company of BFH, has set itself the task of developing and commercialising high-tech electrical drive systems for single-engined aircraft. With regard to a new drive concept, Switzerland's reputation for reliability and precision will play an important role. Development of the high-performance electric motor and the electrical system, battery, management, charging unit, etc. represents the initial stage of the process. The most suitable aircraft for the initial application has proven to be the Votec evolaris from MSW Aviation.


ESReC-SBB battery

Project manager: Andrea Vezzini 

A battery used to supply continuous battery power in railway carriages was completely redesigned and developed. The project aimed to reduce the weight and size of the battery and increase system efficiency.

armasuisse report

At the end of 2015, armasuisse commissioned the BFH-CSEM Energy Storage Research Centre to carry out a technology assessment of batteries containing lithium (LIB). The assessment addresses the issues of inspection guidelines and standards relevant to the use of LIB in the army. This resulted in the study entitled "Technology Assessment and Inspection Guidelines for Batteries Containing Lithium" which has recently been published in the printed version V1.1.

This report is not only of interest to armasuisse and army logistics personnel, but also to anyone who deals with LIBs and is responsible for their procurement, transport, storage, application or disposal.


The Swiss Federal Department of Defence, Civil Protection and Sport (DDPS) financed the projects for this study. The printed version (124 pages) is available from the BFH-CSEM Energy Storage Research Centre in return for a contribution towards costs of CHF 30.00.



The BFH-CSEM Energy Storage Research Centre has a leading position in research and consultancy, thanks to the most modern laboratory facilities for storage research in Switzerland.
