Optimized LTO technology: A Battery Thermal Management System will be developed to maintain the battery in ideal conditions, while controlling temperature increase below 45°C, when 5C discharge current occurs. This progress allows to achieve a powerful battery (>20% of the current one) and reducing the investment cost by down size the battery system, with respect a certain reference application.
Optimized AORFB Technology with better environmental performance.
ABMS is a key innovation in order to optimize the operation and management of the HESS. ABMS is a solution for Battery Health Management, providing a full diagnostic/prognostic assessment, including early warnings, for each battery technology to enhance the maintenance and to provide updated models of each battery to allow an optimal management of the HESS with optimal dispatch of the power solicitations. This solution will also correct any information provided by the BMS on the SoH and the SoC.
Power electronics - an innovative Power converter: the novel power converter based on an interleaved configuration allowing power flow sharing and routing with the aim of optimizing components state-of-health (especially relevant for semiconductors which are one of the elements that fails the most on power converters) as well as increase on the efficiency (which is relevant for the round trip of the HESS) through the usage of novel semiconductor technology based on SiC; which is better suited for medium high power and medium-high voltage applications. In addition, such technology will help reducing the thermal losses (thus, reducing cooling requirements) which are positive for battery SOH.
Optimization and validation via HIL based Digital Twin: Given that about 80% of a issues with ESS controls are software based, the Digital Twin for HESS (DTH) technology makes it possible to lower the time necessary to size, develop, validate and pre-commission a HESS. Furthermore, a DTH enables owners
and operator to lower both CAPEX and OPEX by making the optimal decisions in different stages of the of system lifecycle, from choosing the best units and configuration of devices and sub-systems in the design phase, over virtualized interoperability testing in verification stages, to benchmarking various optimization algorithms.
Devoted method for battery-based HESS integration: A bottom-up approach which leverages the use of advanced modelling to achieve a fast apply of the technology with a high flexibility and customization capability. This is contrary to other solutions in the SoA, where a top-bottom approach, mainly focused in the high control layers, leads to weaker performance in terms of the “chemistry”.
Power Management System:
• High focus into the storage technologies, including advanced models with a continuous update during the project.
• Capability of the control system to integrate multiple chemistries in a single system with extended performance.
• Real-time performance, as most of the current EMS approaches are more focused into a schedule level or an operation in periods of minutes.
• Flexible integration of new assets, modularity and interoperability thanks to the virtualization provided by the State of Function.
