EMONI

THE USE OF EMONI IN THE LiVe RESEARCH PROJECT The project The LiVe research project developed among others by the PEM of the RWTH Aachen University for li- fe-cycle cost reduction in electrical distribution aims at the research of modular structures on the basis of customer requirements. The developed modular system of the electrical drive train is validated on te basis of several pilot vehicles and their tests in the field. Currently, the module and the battery system for the following integration into vehicles are struc- tured. Application of EMONI To achieve the aim of the LiVe research project for a cost reduction in electric distribution vehicles over their life cycle, importance has been attached to cost-efficient and powerful materials already during the design and the planning phase of the entire vehicle. For the use as voltage collectors which are to be la- ser-welded for cell monitoring between the cell tabs of two pouch cells, material meeting the requirements for a very good weldability and formability with providing good electrical properties at the same time was looked for. To this effect, the PGW EMONI material distinctly showed good performance data during production and the first qualifying tests of the entire system. With respect to the manufacturing-based and the electrical performance data, the EMONI material of PWG provided excellent re- sults as compared with the materials used in the market to date.

Pickhardt & Gerlach developed the “EMONI“ product to respond to the specific requirements for the new market of e- and micro-mobility. EMONI is excellently suitable for the use in e-mobility and micro-mobility in battery sys- tems of vehicles. To have this material tested neutrally, the RWTH Aachen University was entrusted with an inde- pendent study. 2
