This work package solidifies the science-to-technology transition by demonstrating the proof-of-concept of the prototype BTMS.
- Based on the LVG designs, an optimization procedure will be performed for the most promising features. Deterministic (e.g. 1D modelling coupled to Response Surface Methodology) and non-deterministic (e.g. genetic algorithms) approaches will be followed, according to which an objective function is derived encompassing all design parameters.
- The CFD models developed and validated in WP2 based on the benchmark configurations, which include already optimized parameters, will be coupled to electrochemical/thermal models to account for the battery transient thermal behavior and employed in simulations of the realistic BTMS layouts. A series of simulations will provide input to the design procedure for the evolution of the device macroscopic layout (e.g. battery stacking density, overall dimensions) to its final form.
- A prototype BTMS will be manufactured. The prototype should be designed considering the optimal geometry (LVG designs mentioned above) and attractive surface features from WP1.
4. The prototype BTMS will be evaluated in terms of battery performance and parasitic power. A battery test station will be developed and used to control the charge/discharge of the cells at rates up to 10C. The hydraulic flow loop and instrumentation developed in WP1 will be employed. In both experimental tasks, the BTMS performance will be compared against baseline cases with conventional geometries and heat transfer fluids.
