Invitaiton To Tender - Battery Testing

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 batter…
