Description
NPL requires a combined Potentiostat/Galvanostat/Frequency Response Analyser system for battery testing with at least 5 channels each having electrochemical impedance spectroscopy (EIS) capability incorporated, i.e. not multiplexed. The system shall be able to test batteries at currents ⥠100 A and voltages ⥠50 V, either directly via the system channels or in conjunction with internal or external boosters, to allow fast charge/discharge rates and to study large cells, modules and packs. It is additionally required that the channels can also perform low current and voltage measurements with a minimum current ⤠0.1 mA. We require the ability to characterise performance and lifetime of batteries using such a test system. The test facility will be capable of accurately measuring charge and discharge curves, cycle capacity, state of charge and state of health (via EIS) not only for Li-ion batteries but also other emerging battery chemistries. As a National Measurement Institute, measurement resolution and system performance are a very high priority. A low footprint for expansion of number of channels, the ability to save data in internal memory during long term tests and software for battery analysis are also desirable.
