Do not distribute without written consent Conductance, Impedance & Resistance (IEEE Standard 1188-1996) Conductance measurements can be performed by applying a voltage of known frequency and amplitude across a cell / unit and observing the ac current that flows in response to it. The conductance is the ratio of the ac current component that is in-phase with the ac voltage, to the amplitude of the ac voltage producing it. (p.15) Impedance measurements can be performed by passing a current of known frequency and amplitude through the battery and measuring the resultant ac voltage drop across each cell/unit. The ac voltage measurement is taken between the positive and negative terminals of individual cells or the smallest group of cells possible. Compute the resultant impedance using Ohm’s law. (P.15) Resistance measurements can be performed by applying a load across the cell/unit and measuring the step change in voltage and current. The ohmic value is calculated by dividing the change in voltage by the change in current. (p.15) CONDUCTANCE TECHNOLOGY It Starts with the technology Conductance Measurement 1. 2. 3.

(Clause 5.11.3 Regarding Cell Matching) Due to review of the clause 5.11.3 in which conductance measurement instead of impedance measurement have been specified, the word “impedance” has been replaced with word “conductance” in these 2 clauses.
