The Department of Electrical Engineering invites applications for a 3-year PhD position associated with the project TOPChargE, “Variable Topology Battery System for Optimising Grid Load during High-Power Charging of Electric Vehicles” and interacting with the H2020 project InsulaE as well as project BOSS. TOPChargE aims at developing and demonstrating a cost-effective and market-based battery buffered fast charging solution. Based on a new battery management technology the projects highlights a strong innovation motion among academia, local innovation industries (Nerve Smart Systems and Fremsyn Aps) and a large energy stakeholder (OK a.m.b.a.). 

Battery energy storage systems (BESSs) are key to fully sustainable energy systems. Transitioning to a 100% renewable based energy system prompts a paradigm shift in perception and use of battery electric storage systems. New advanced control and innovative technical solutions must be developed in order to meet future needs. 

Advanced battery management & control (AC battery concept) 
A new and proprietary battery management technology, BMT, enabling a modular build, reconfigurable topology and advanced operation, opens for a vast number of new applications and markets. Potentially, the new BMT may change how electric storage is perceived and used. Charging and discharging may be directly adapted a selected voltage by engaging or bypassing individual cells without the need of conventional converters [1].

The PhD student, the candidate, shall investigate the theoretical potential of this technology and through modelling and experiments explore fundamental limitations and challenges of the technology. The candidate shall consider concepts such as AC operation w/o need of converters, short circuit power, voltage ride through and inertia as well as experimental aspects such as generic constraints (switching and communication latency, component dynamics, tolerances, etc.). Further, the candidate should expect to assist in relation to the battery projects TOPChargE, InsulaE and BOSS with testing of BESS according to grid codes relevant for EV fast charging (100kW-1MW) and grid connected batteries (e.g. the Danish TF3.3.1 and IEEE 1547-2018/1547.1-2020), hence knowledge of power system would be beneficial. New ideas and thinking out of the box is encouraged in this PhD study.
