The project will provide the scientific community with traceable measurements for the characterisation of SCs and banks of SCs. The validity of the proposed measurement techniques will also be verified in operation (i.e., with ripple and harmonics) and consider new types of hybrid SCs. The guidelines for these measurements can be used by other metrologists to meet the measurement needs of the national industries producing and using SCs. The project will provide scientific and technical knowledge on such precision measurement systems to electrical metrologists, researchers in the field of storage and its applications in e-mobility, energy and power electronics from related academic fields for further development. The consortium will provide an overview of the measurement accuracy obtainable with the most well-known DC measurement techniques and Electrochemical Impedance Spectroscopy (EIS) techniques, that currently does not exist either for manufacturers or in scientific publications, except for individual analyses under controlled conditions and generally on a few types or sizes of SCs.
NMIs will deliver a report containing the CMCs concerning the characterisation of SCs, compliant with those published in the KCDB website, which will be ready for use in NMIs depending on market demand in the various countries. These CMCs will be of high relevance to the metrology community, as at the moment no NMIs deal with high capacitance measurements, especially in the 10 F – 3000 F range, which is the one that is receiving great interest in applications.
The two large open access databases that group together a significant amount of relevant data on different type of SCs, will enable academic communities (both metrological and non-metrological with limited or no capabilities to perform measurements and characterisations on SCs) to undertake further research activities including analysis of data and information about SCs’ variability versus charging conditions, versus charging patterns, versus SoC/SoH and related aging.
The development of rapid techniques for the definition of SoC/SoH also requires the development of both analysis and measurement techniques. These developments will benefit both the metrology and scientific community since they can improve and speed up the assessment of these parameters.
