Automatic Digital Battery Cell Capacitance Measurements.

Abstract

An instrument of general applicability constructed to automatically measure the capacitance (or impedance) of battery cells is described. Full, automatic, electrical characterization of a battery cell by a single device is made possible with the instrument's added ability to be programmed to charge and discharge the cells. The capacitance can be monitored with a precision of 0.05% and an accuracy of 1%. Data are presented for the capacitance of the nickel electrode at low states of charge as an example of application of the instrument. (Author)
