Focus is on application-driven design of battery packs and its thermal management design aiming at creating high-energy / power-dense battery packs in a cost-effective manner. At this moment no universal battery topology exists and functional layout and shape influences largely the overall battery performances and specification. Moreover, automated creation of simulation models that match desired modular pack topology and include (thermal subsystems), e.g. cooling plate connections allowing electrical and thermal response analysis (for fast charging) is researched. Thermal, safety operational and other concurrent system architecture constraints are considered in the design tradeoffs aiming at optimal cell-to-vehicle integration. Current research applications: cars, trucks, buses, drones, planes, ships.
