EMADI – Developing an economical measurement and billing system for dynamic wireless power transfer systems

EMADI aims to develop a prototype for an information and communication system. This system will measure energy use, communicate, and bill users of dynamic wireless power transfer systems. The influence of dynamic wireless power transfer on the aging of vehicle batteries will be investigated using aging models and life expectancy prognosis. The sustainability aspects of such a system will also be examined.

As a partner in this project, the chair of Electrical Energy Storage Technology investigates generic aging models. Conventional aging models are parametrized using the results of aging studies on batteries. The project aims to generate data-driven aging models. These should represent the properties of typical material combinations of lithium-ion-cells (e.g., NMC-cathode and graphite anode). They should be scalable to use them with manufacturer-provided data sheets. Aging and life expectancy could, therefore, be predicted. Laboratory studies validate this with selected cells. Based on the aging models, life expectancy prognoses are generated. These are then used to compare the battery life of inductively charged batteries with inductively charged ones. Life cycle analysis is then done. Strategies to reduce aging while charging inductively are then deduced.

Load profiles are also considered in this project. The load profiles generated by partners are refined into high-resolution battery load profiles. These will be used in the validation mentioned above measurements.

The resulting aging models and battery load profiles will be open-sourced to maximize research and industry benefit.
