Potentiostat/Galvanostat for Battery Testing

Tender description

The National Physical Laboratory [NPL] requires a Potentiostat/Galvanostat for Battery Testing with at least 4 channels each having electrochemical impedance spectroscopy (EIS) capability. A maximum current of ? 4 A is required on three channels, with a maximum current of ? 10 A on the other channel. 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 and the ability to save data in internal memory during long term tests are also desirable. Keywords: Battery Test Station
